Description
SPECIFICATION
Spot-type disc brake
The present invention relates to a spot-type disc
brake, in particularforan automotive vehicle, ofthe
kind comprising a brake caliper straddling the edge of a brake disc which caliper is supported slidably on a guideelementarrangedin paralleltothe brake disc axis, which includes at least one brake cylinder, wherein brake shoes are adapted to be pressed againstthe brake disc from both sides upon brake application, and wherein the disc brake has a brake support membersecured to thewheel axle.
In known floating-caliper disc brakes of this kind, the brake support member has in cross-section the approximate configuration of an L or of a right angle, with one leg being fastened to the wheel axle, for instance to the steering knuckle, in parallel to the brake disc, while the second leg straddles the brake disc at the level ofthe brake caliper, abuts slidably on the brake caliper on a parallel relative to the brake disc axis on the disc entrance side and on the disc leaving side and is therefore able to support the brake caliper in both directions of rotation and to receive the circumferential and the braking forces, respectively.
To guide the brake caliperthat is slidable relative to the brake support member, grooves which are shaped into the brake support member or into the brake caliper on the disc entrance side and on the disc leaving side will suffice in combination with corresponding edges atthe brake caliper or at the brake support member, respectively, which edges engage said grooves, or additional guiding arrangements may be provided.
It is also known alreadyto support the "floating" brake caliper in a slidingly displaceable manner on two bolts arranged in parallel to the brake disc axis radially spaced from one another. The two bolts are secured either directly to the wheel pivot or to a vehicle frame member. In a known design (DE-A1 30 44185), the brake caliper only carries the outer brake pad and is guided by only one of the two bolts. The opposite, that is to say, the inner brake pad, is mounted on a supporting plate which will slide on the second guide bolt during braking. Upon actuation of the brake, the supporting plate will be acted upon by the hydraulically driven brake cylinder that is arranged on the inner leg ofthe brake caliper.Moreover, the innersupporting plate is in engagement with a guiding and transmitting member that bears against the brake caliper on both sides, i.e. on the disc entrance and on the disc leaving side, in such a manner, that, though displacement in parallel to the brake disc axis is possible the circumferential force exerted on the supporting plate will be transmitted onto the brake caliper, too, and through the latter partially onto the second guide bolt. There can be expected an approximately even distribution of the circumferential and the frictional forces, respectively, ontothetwo guide bolts.
The employment of two guide bolts implies manufacturing and mounting effortsthatare not inconsiderable. Besides, it is difficu It to align the guidance in such a way that, in the long run and in any state of wear ofthe pads, the brake forces will be transmitted evenly onto these elements in order to prevent canting orjamming ofthe bolts in the slide bearing and thus a
disadvantageous increase ofthe forces required for caliper displacement.
A disc brake floating on only one guide bolt, which
brake is specifically provided for motorcycles and which is designed as a hinged caliper brake, is likewise
previously known (German printed and published
patent application 2839 195). In this arrangement, the entire brake abuts laterally of the brake disc against a large surface of a supporting member, the guide bolt being inserted about in the middle of the abutment surface and retaining the brake on the supporting member. The brake shoes are retained in the brake caliper by means of an extended portion ofthe guide bolt and by a second shorter boltwhich latter extends through the brake caliper only, the two bolts being required to receive in total the circumferential and the frictional forces, resppectively.One can be sure that even distribution of forces from the brake shoes onto the retaining bolts, from these onto the brake caliper and onto the guide element as well as onto the supporting surfaces will be attainable in this design at the most in the event of relatively small brake forces.
It is an object of the present invention to provide a spot-type disc brake which, compared with known brakes ofthis type, is distinguished by less manufacturing and mounting effort needed. In addition, it is desired that the force to displace the brake caliper that is required forthe application ofthe brake shoes when braking be as small as possible, in order to ensure ease of brake actuation and to prevent canting or jamming ofthe brake-caliper guidance on the guide element even after a longer period of use and in any state of wear.
According to the invention in its broadest aspect, a spot-type disc ofthe kind referred to is characterised in that the brake support member is designed in the shape of a retaining element extending in parallel to the brake disc on one side of the brake disc, that the brake caliper is supported on the brake support member on the disc-leaving side, in respect ofthe main direction of rotation of the brake disc, and that the guide element is arranged close to the discentrance side, in respect ofthe main direction of rotation.
According to an expedient embodiment ofthe present invention, the brake shoe located on the side of the brake support member and the pad carrier of this brake shoe, are supported in the brake caliper and, in addition, directly on the brake support member against the braking forces occurring in the main direction of rotation when braking and transmitted onto the wheel axle. The braking force component to be received by the guide element will thereby be rendered small.
Furthermore, it is provided in accordance with another embodiment that the brake caliper orthe brake support member has a projection on the disc-leaving side, in respect of the main direction of rotation ofthe brake disc, the projection engaging a corresponding notch in the brake support member or in the brake caliper which notch serves as a guide and is designed for example in the shape of a groove in
parallel to the brake disc axis, the projection securing the brake caliper against torsion ortilting due to force components acting radially upon the brake caliper.
It is a further essential advantage ofthe present invention thatthe brake support member, due to its very straightforward design, can be designed integral- ly with the wheel axle or with the wheel housing. This is so because the brake support member is substantially composed of merely one elongated plate or a corresponding clip and does not necessitate any bent-off portions or other parts extending beyond the brake disc.
It is, however, likewise possible to design the brake support member as a separate component and to secure it to a corresponding flange atthe wheel axle or at the wheel housing by means of a fastening element, for example by bolts, arranged close to the discentrance side and close to the disc-leaving side with the fastening element that is close to the disc-entrance side in respect ofthe main direction of rotation being able to serve simultaneously for attachment of the guide element. Suitably, the bolt serving as a guidance carries a guiding sleeve on which latter brake caliperwill be disposed floatingly, i.e. displaceable in parallel to the brake disc axis.
In general, it is assumed to be an advantage to have the brake support member and the portion ofthe brake caliper and of the brake housing, respectively, which contains the brake support member, arranged on the same side of the brake disc, preferably on the inner side of the wheel.
According to another embodiment of this invention, the brake caliper contains an aperture in the portion bridging the brake disc, in which the brake shoes are retained by means of pins, arranged in parallel to the brake disc axis, and by means of spreading springs, the aperture being so dimensioned as to permit the brakeshoesto been outand put back in through the aperture in parallel to the brake disc in a radial direction after detachment or removal of the pins. This simplifies the brake shoe replacement considerably, since the brake and the brake caliper, need not be disassembled or loosened eitherforthis purpose.
Suitably, the brake caliper is slidably guided in the brake support member on the disc-leaving side, in respect of the main direction of rotation of the brake disc, in parallel to the brake disc axis. The caliperdisplacing forces will thus be increased only in the event of heavy braking and in this case onlyto a minor degree. It will be ensured thereby that the braking forceswill betaken on the brake support memberin any position the floating caliper assumes.
In the opposite direction, i.e. when driving backwards, the predominant portion ofthe braking forces will be transmitted onto the guide element, which does not have any effect, however, because the load onthe brake ofan automotivevehicle is in principle considerably higherin the forward direction than it is in the opposite direction.
The comparatively small manufacturing effortfor the disc brake according to the invention stems above all from the very straightforward design ofthe brake support member already described, but likewise from the compact design ofthe brake caliperwhich is secured to the wheel axle by only a single bolt, i.e. the guide bolt, and which combines in itself all the important parts ofthe brake, that is to say, the brake shoes and the the brake-actuating device. Obviously, these features also serve to reduce the mounting effort.
An embodiment ofthe invention will now be described byway of example with reference to the accompanying drawings, in which Fig. is a side view of a spot-type disc brake taken in cross-section along the line A-B in Fig. 2, Fig. 2 is a top plan view on the disc brake of Fig. 1, Fig. 3 is a cross-sectional view ofthe disc brake of
Fig. 1 taken along the line C-D.
Referring to the embodiment of the invention illustrated in Fig. 1, the spot-type disc brake comprises essentially a brake caliper 1 and a brake support member 2. The brake pads 3,4 (compare Fig. 2), which are each secured to a pad carrier 5,6, as well as the wheel brake cylinder7, which latter, upon brake application, presses the brake shoes from both sides against the brake disc (not shown), are united in the brake caliper 1. To retain the brake shoes, retaining pins 8,9 are used which will be inserted into corresponding bores in the brake caliper and will be plugged through corresponding openings 10, 11 in the pad carriers 5,6.
According to the invention, the brake support member has the shape of an elongated retaining element arranged on one side ofthe brake disc which element, as will be appreciated, may be designed likewise as an integral component of the wheel axle and the wheel housing or of the wheel pivot. In the embodiment of this invention shown by way of example in Figs. 1 to 3, the brake support member is secured to the wheel axle by means of two bolts 12, 13.
The flange 14 provided therefor and connected directly to the wheel pivot, for instance, is indicated in Fig. 3, however, only its end portion is shown which contains the two fastening lugs 15,16 (see Fig. 2) extending through which arethefastening bolts 12 and 1 3. In 13. lntheembodimentshown,thethreads17,18 have been tapped intothe brake support member2for mating with the bolts 12, 13. twill, however, be likewise possible without difficulty, and will even be favourable in some cases, to shift the position of the flange 14 inwardly and to the brake disc, respectively, by exchanging the location of the flange 14 and that of the brake support member 2, compare Fig. 3.In this case, the screw bolts 12,13 would have to be plugged through the brake support member 2' and screwed intotheflange 14 connected to the wheel axle.
The brake shoes, by which in each case is meant the assembly of brake pad 3,4 and pad carrier 5,6, are prevented from rattling and from undesired parallel displacements by respective spreading springs 19, (see Fig.1 in connection with Fig.3, - in Fig.3the springs are not shown), which resiliently engage the retaining pins 8,9 from below and which admit parallel displacement ofthe brake shoes on the retaining pins, which is in particulardecisiveforthe functioning of the brake shoe 3,Sthatwill be displaced bythewheel brakecylinder7 upon brake application.
Apart from the guidance at the brake support member 2 described hereinbelow, the brake caliper 1 is merely held through the bolt 12. This screw bolt simultaneously serves for fastening the brake support member 2' to the flange 14and as a carrier of a sleeve 20 on which latterthe brake caliper 1 isarranged slidably in parallel to the brake disc axis. This sleeve 20, (compare Fig. 2), extends up to the fastening lug 16 oftheflange 14 and possesses outwardly a smooth surface protected against the ingress of dirt by cup seals 21,22 on both sides. Disposed on one arm or an extension 23 ofthe brake caliper 1 is the bore conformed to the outer diameter of the sleeve, which bore serves to mount the brake caliper onto the sleeve 20.
The guidance and support ofthe brake caliper on the disc-leaving sideofthe brake, which best can be taken from Fig. 1, is of great importanceforthe load capacity ofthebrakes.The main direction of rotation ofthe wheel and ofthe brake disc, respectively, is symbolised bythe arrow 24 in Figs. 1 and 2. When braking from this direction of rotation, the braking and the frictional forces, respectively, will be transmitted from the brake shoes 3,5 and 4,6 respectively, via the contact surfaces 25 onto the brake caliper 1 and from the lattervia the contact surfaces 26 onto the brake support member 2. Moreover, partoftheforceswill be transmitted from the brake shoe 3,5 directly via the abutment surface 27 onto the brake support member 2.The guide element which is composed of the bolt 12, the sleeve 20 and the portion in the arm 23 (Fig. 1) of the brake caliper 1 receiving the sleeve, and which is arranged on the disc-entrance side will thereby be relieved from thefrictional forces to an appreciable degree, as a result whereof, as has been explained previously, the forces for displacement ofthe brake caliperwill become small even in the event of high braking forces. Asa result, the danger of the sleeve 20 canting orjamming in the guide bore of the arm 23 will be reduced considerably.
To guide the brake caliper as well as to receive the forces which a redirected radially outwardly in respect ofthe brake disc and which would tiltthe brake caliper in the guidance 12,20when driving backwards, a guide groove 28 is machined in the brake support member 2, as is illustrated, or atthe same position in the brake caliper, which guide groove extends in parallel to the brake disc axis and thus does not hinder the brake caliperfrom lateral displacement. A corresponding projection 29 atthe brake caliper or atthe brake support member, respectively, engages the guide groove 28.
Pad replacement is particularly simple with the disc brake according to the invention. Arranged in the portion bridging the brake disc, i.e. in the portion of the brake caliper 1 that is disposed over the periphery ofthe brake disc, is an aperture whose dimensions conform to the entire width ofthe brake shoes so that, afterdetachmentand removal ofthe retaining pins 8,9 and ofthe associated spreading springs 19, the brake shoes can be taken out radially outwardly and replaced by new linings in a corresponding fashion, without there being the need for disassembly of the brake caliperfrom the brake disc or even tilting of the brake caliper. The insertion ofthe spreading springs 19 after mounting ofthe new brake shoes is likewise possible without difficulty, as can be seen from Fig. 2 in particular.
