Description

Vehicle bracket assembly

Technical field

The utility model relates to a kind of vehicle bracket assembly.

Background technology

Vehicle bracket assembly is applied in the suspension of car chassis, the bracket body of vehicle bracket assembly is metallic article, usual quality does not have large problem, but the bulb branch unit installed on bracket body, the situation of middle rubber bush and rear rubber bush is then completely different, the structure design of rubber bush affects fatigue resistance and the damping property of lining, the structure design of bulb then affects the rotating mass of bulb, and in prior art, rubber bush and bulb design have problems all in various degree, this is all to the product design of bracket assembly with cause adverse effect service life.

Summary of the invention

In view of the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide that a kind of rubber bush anti-fatigue performance is good, damping performance is good, and bulb rotating mass is good, effectively improves the quality of products and the vehicle bracket assembly in service life.

The utility model takes following technical scheme:

Vehicle bracket assembly, the bulb branch unit comprising bracket body and install on bracket body, middle rubber bush and rear rubber bush, it is characterized in that: described rear rubber bush is managed by injection-compression molding back bush together, back bush rubber and back bush outer tube composition, Guan Weicheng " king " font in back bush Intermediate Gray circular hole, the shaped piece of upper and lower sides band bar hole, back bush outer tube is the pipe part that endoporus left and right sides increases wall thickness, described back bush rubber comprises internal layer colloid, outer colloid and interlayer colloid, internal layer colloid to be wrapped in back bush outside pipe, outer colloid is wrapped in back bush outer tube, deformation space is left between ectonexine colloid, interlayer colloid is located at left and right and is connected by ectonexine colloid.

Described middle rubber bush by injection-compression molding together in lining pipe and middle bushing rubber form, the front/rear end of middle bushing rubber is provided with convex annular edge, and in middle lining, the aft end face of pipe is provided with convex annular edge.

Described bulb branch unit comprises spherical shell, ball seat, bulb, capping and saucer washer, the sphere hole that first sphere of bulb is had by spherical shell supported, the sphere hole that second sphere of bulb is had by ball seat supported, ball seat loads in spherical shell from the bottom opening of spherical shell, saucer washer is located at the bottom of ball seat, capping is located at the bottom of saucer washer, and the bottom opening of spherical shell is provided with in-flanges by spacing to capping, saucer washer and ball seat inner at spherical shell.

The upper shed of spherical shell is stretched in outside the bearing pin be connected with described bulb, the upper shed of spherical shell is sealed by dust boot, the lower end of dust boot is by folder spring buckle tightly at spherical shell cylindrical, and jump ring banding is passed through at bearing pin cylindrical, the sheathed rib in the position that bearing pin is connected with bulb in the upper end of dust boot.

In technique scheme, the utility model from lining and bulb two aspect the structure to bracket assembly improve.First from the structure design of rear rubber bush, utilize the special shape of pipe in back bush, make it specific preferentially stressed in the radial direction, prevent rubber in working process from occurring local ageing, extend the anti-fatigue performance of rear rubber bush on the whole, make the damping performance of rear rubber bush good simultaneously, so, just improve product design and the service life of bracket assembly from lining aspect.Then the rotating mass problem of bulb is solved from the structure design of bulb: work as bulb, ball seat, saucer washer and capping load after in spherical shell, by the flange of spherical shell bottom opening by capping, saucer washer and ball seat spacing inner at spherical shell, the degree of flange can be guaranteed by riveting press equipment, the error of accessory size is then eliminated by the distortion of saucer washer, so just can ensure that the contact between ball seat and bulb is consistent substantially, thus meet the designing requirement of bulb to rotating torque, realize bulb better to rotate, ensure bulb rotating mass, in addition, the setting of dust boot solves dust-proof problem, and arranging when solution bearing pin rotates with bulb of rib collides to spherical shell the damage caused, and also all effectively ensures bulb rotating mass.Product design and the service life of bracket assembly is so just improve from bulb aspect.
