Abstract
The utility model discloses a whole highly-sealed wheel cylinder assembly for a disc brake. The whole highly-sealed wheel cylinder assembly comprises a wheel cylinder shell body (1), a wheel cylinder piston (5), a brake block (2) and a shoe guiding pin (8). A shoe spring (3) is arranged on the shoe guiding pin (8). A piston plug (7) is arranged on the wheel cylinder shell body (1) and at the position corresponding to the wheel cylinder piston (5). The wheel cylinder shell body is of an integral structure. A braking oil way (11) is arranged in the wheel cylinder shell body. An outlet of the braking oil way is an air releasing hole (12). Another outlet (13) is sealed by a steel ball (9). The whole highly-sealed wheel cylinder assembly is small in occupied space, mounting of the wheel cylinder assembly can be well achieved, an oil way auxiliary hole of the braking oil way is sealed by the steel ball, position clamping is firm, and sealing performance is good. Accordingly, the quality and the performance of a brake are improved, and the safety of vehicle traveling is greatly improved.
Description
Technical field
The present invention relates to a kind of Brake for vehicle, belong to electric motor car and manufacture field, specifically relate to point pump assembly (being brake calipers) that a kind of electric motor car break is used.
Background technique
Electric motor car is an emerging vehicle, and its load-carrying and F-Zero are between bicycle and motorcycle, and the main flow of its break is that front and back wheels all adopts drum brake substantially at present, and its braking effect is unsatisfactory.Because drum brake heat dispersion is poor, in braking process, produce amount of heat, very easily cause that brake block temperature raises, friction factor declines, cause heat fade, retardation efficiency decline, insensitivity variation and braking in because excess Temperature produces noise; Once rainwater enters drum brake, can make friction factor decline, cause water fade, and water is difficult, and out water is restorative poor, retardation efficiency declines, and the Security of driving reduces.
This electric motor car break is disk type braker, is made up of main pump assembly, point pump assembly (being brake calipers), brake disc etc., and its brake disc is exposed in air and high speed rotating, and radiating effect is good; Braking ability is stable; Brake disc is followed wheel and is rotated together, water or mud can be thrown away, and therefore water is restorative better; Braking ability is stable, has greatly improved the Security of driving; Long service life and at when braking noise free, it is convenient to change.The trend of industry development is to substitute drum brake with disc type brake.But its point of pump assembly generally adopts Split type structure, that its deflating valve reaches is more outside point pump case, compared with long and by bolt seal, take up room large, be unfavorable for point pump case to install in electric motor car and easily swipe, and its oil circuit auxiliary hole is by " 0 " type seal with elastometic washer, sealing is not high, has the possibility of leakage of oil.Thereby affect the overall performance of break.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of favorable sealing property, overall high sealing formula easy for installation to divide pump assembly.
Object of the present invention realizes by following technical solution: overall high sealing formula is divided pump assembly, comprise a point pump case, wheelcylinder piston, brake block, shoe plate pilot pin, on this shoe plate pilot pin, shoe plate spring is housed, in this point of pump case and with wheelcylinder piston corresponding part, piston screw plug is housed, described point of pump case is monolithic construction, in described point of pump case, be provided with brake circuit, an outlet of this brake circuit is that vent hole, its another outlet are sealed by steel ball.
Adopt after structure of the present invention, an outlet of the brake circuit of its point of pump case is that vent hole has replaced the more deflating valve of original protrusion, and this vent hole position is basic and divide pump case in same plane, takes up room less, is conducive to the installation of point pump assembly; Another outlet (being oil circuit auxiliary hole) of this brake circuit is sealed by steel ball, and screens is firm, favorable sealing property.The design of one's duty pump assembly has taken into full account the feature " speed between between bicycle and motorcycle, load-carrying is greater than bicycle and is less than motorcycle, car body strength also between bicycle and motorcycle " of electric motor car.Thereby improve the quality and performance of break, greatly improved the Security of driving.
Brief description of the drawings
Below in conjunction with accompanying drawing and mode of execution, the present invention is described in further detail.
Fig. 1 is the structural representation that the present invention's entirety high sealing formula is divided pump assembly.
Fig. 2 is the rear view of Fig. 1.
Fig. 3 is the plan view of Fig. 2.
Fig. 4 is the B-B sectional view of Fig. 3.
Fig. 5 is the C-C sectional view of Fig. 3.
Embodiment
Known referring to figs. 1 through Fig. 5, the present invention is applied to the overall high sealing formula of the disk type braker in electric motor car and divides pump assembly, comprise point pump case 1, wheelcylinder piston 5, brake block 2, shoe plate pilot pin 8, on this shoe plate pilot pin 8, shoe plate spring 3 is housed, in this point of pump case 1, and with wheelcylinder piston 5 (mounting point) corresponding part, piston screw plug 7 is housed, described point of pump case 1 is monolithic construction, in described point of pump case 1, be provided with brake circuit 11, an outlet of this brake circuit 11 is that vent hole 12 (is sealed by venting screw plug 10, as shown in Figure 1), its another outlet 13 (being oil circuit auxiliary hole) are sealed (as Fig. 3 by steel ball 9, shown in Fig. 5).
Wherein, between wheelcylinder piston 5 and point pump case 1, rectangular seal 4 is housed, between piston screw plug 7 and point pump case 1, seal ring 6 is housed; Vent hole has replaced original deflating valve, and described vent hole 12 is sealed by venting screw plug 10, dismantles this venting screw plug 10 when use.
Claims (2)
1. overall high sealing formula is divided pump assembly, comprise a point pump case (1), wheelcylinder piston (5), brake block (2), shoe plate pilot pin (8), on this shoe plate pilot pin (8), shoe plate spring (3) is housed, in this point of pump case (1), and with wheelcylinder piston (5) corresponding part, piston screw plug (7) is housed, it is characterized in that: described point of pump case (1) is monolithic construction, in described point of pump case (1), be provided with brake circuit (11), an outlet of this brake circuit (11) is vent hole (12), its another outlet (13) is sealed by steel ball (9).
