Abstract
The utility model discloses an automobile plate spring with a composite bush. The two ends of a first reed, the two ends of a second reed and the two ends of a third reed are clamped together through a wrapping clamp (5). The composite rubber bush is installed in a spring eye at the rear end of the first reed. The front end of the first reed, the front end of the second reed, the front end of the third reed and the front end of a fourth reed are clamped together through a straight clamp (1). Two clamp gaskets (2) are arranged inside two side plates of the straight clamp respectively. The front end and rear end of each clamp gasket (2) are respectively provided with a covered edge (2a). A gasket positioning hole (1a) is formed in the middle of each side plate of the straight clamp, wherein each clamp gasket (2) is provided with a boss (2b) which extends into the corresponding gasket positioning hole and is matched with the corresponding gasket positioning hole. A rear end bush of the plate spring is replaced by the composite rubber bush, so that the abrasive resistance of the bush is improved; besides, by additionally arranging the straight clamp and the clamp gaskets, the technical problem that vibration and noise are generated due to the fact that the wrapping clamp makes contact with the reeds in the using process is solved.
Description
Technical field
The utility model technical field of automobile parts, is specifically related to a kind of automobile steel sheet spring.
Background technique
Autobody sheet leaf spring (abbreviation leaf spring) is assembled by some reeds.That leaf spring has is simple in structure, reliable operation, the advantage such as with low cost, easy to maintenance, in automotive suspension, is widely used.While assembling single reed, except bolt in the middle of using, also need clip.As shown in Figure 4, the clip on leaf spring mostly is double team 5, and double team is clipped together polylith reed 3, then by rivet 6, the bottom of double team 5 is fixing with a reed 3 of below.Although double team has been reserved a gap between when design and reed, in using process, can contact with reed unavoidably and produce and shake and noise.
In addition, lining before and after leaf spring in grasswort is General Purpose Rubber lining, and because leaf spring normally can only rotate front end grasswort fixed position, rear end grasswort can move and can rotate, therefore the frictional force that aft-end liner in use bears is larger, need to often change.
Model utility content
The purpose of this utility model is to improve the wear resistance of damping effect, working life and the lining of leaf spring.
For this reason, a kind of leaf springs of car with composite bush that the utility model provides, first reed (3a) of described leaf spring, the second reed (3b), the 3rd reed (3c) and the 4th reed (3d) are locked together by middle bolt (4) and nut (7), described the first reed (3a), clip together by double team (5) respectively at the two end part of the second reed (3b) and the 3rd reed (3c), and by rivet (6), double team (5) is fixed on the 3rd reed (3c), key is: before described the first reed (3a), rear two ends are respectively provided with grasswort, General Purpose Rubber lining is housed in front end grasswort, compounded rubber lining is housed in the grasswort of rear end, the front end of described the first reed (3a), the second reed (3b), the 3rd reed (3c) and the 4th reed (3d) is clipped together by straight clip (1), and by rivet (6), straight clip (1) is fixed on the 4th reed (3d), described straight clip (1) becomes " U " shape by steel plate bending, in the biside plate of straight clip (1), is respectively provided with a clip pad (2), and the rear and front end of described clip pad (2) is provided with bound edge (2a), for wrapping up the straight clip (1) of respective side, the middle part of the side plate of described straight clip (1) has pad positioning hole (1a), is provided with and stretches in pad positioning hole (1a) and the boss (2b) mating with pad positioning hole (1a) on described clip pad (2).
Be preferably, described clip pad (2) adopts nylon injection-molding moulding, can be also that other existing vibration-absorptive material is made.
Be preferably, described pad positioning hole (1a) is circular hole, and correspondingly, described boss (2b) is round boss.Circular hole is convenient to be installed and processing, has further reduced manufacture cost, has improved manufacturing efficiency.
The beneficial effects of the utility model are:
(1) aft-end liner of leaf spring is replaced by compounded rubber lining, has improved the wear resistance of lining, reduced the trouble of changing, and front end General Purpose Rubber lining can meet usage requirement, does not therefore need to change, and has saved to a certain extent manufacture cost;
(2) in addition, by setting up straight clip and clip pad, solved in use, double team contacts with reed and produces and shake and the technical problem of noise; Meanwhile, straight clip is compared existing double team, and structure is more simple, processes also convenient.
