Balancing suspension and automobile applying same

Abstract

The invention discloses a balancing suspension for an automobile. The balancing suspension comprises a balancing shaft (31), a balancing shaft seat (32) and a plate-type spring seat (34), wherein the balancing shaft seat (32) is sheathed outside the balancing shaft (31); the plate-type spring seat (34) is arranged at the outer side of the balancing shaft seat (32) and is connected with the balancing shaft (31) through an outer bearing (35) and an inner bearing (36); lubricating oil for lubricating the outer bearing (35) and the inner bearing (36) is arranged in the plate-type spring seat (34); a shaft shoulder (311) is arranged on the balancing shaft (31); and the inner side wall and the outer side wall of the shaft shoulder (311) are respectively fit to the outer side wall of the balancing shaft seat (32) and the inner side wall of the inner bearing (36). The balancing suspension has the advantages that the lubricating oil in the plate-type spring seat can be prevented from leaking, further the bearings and the balancing shaft are prevented from being abraded, and the service lives of the bearings and the balancing shaft are prolonged. The invention also discloses the automobile comprising the balancing suspension.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a balance suspension for automobiles. In addition, the present invention also relates to an automobile using the above balanced suspension. Background technique [0002] When a multi-axle vehicle encounters bumps or potholes on the road during driving, it will cause uneven loads between the bridges, affect the overall driving force or cause overloading of a single bridge; in addition, when the car brakes, it will also Affects braking performance due to load transfer. In order to solve the above problems, balanced suspension is usually used on multi-axle vehicles. [0003] Please refer to figure 1 , figure 1 A schematic diagram of the assembly of the balanced suspension and the double rear axle. [0004] Such as figure 1 As shown, the balance suspension 3' comprises a balance shaft 31', a balance shaft seat 32', and a leaf spring 33' connected to the top of the balance s...

Problems solved by technology

[0007] However, with the above structure, when the balance shaft 31' and the leaf spring 33' are subjected to upward heavy loads, the balance shaft 31' will be bent upward, and the sealing ring 311' will be gradually worn during use, causing the leaf spring The lubricating oil in the seat 34' leaks along the gap between the retaining ring 312' and the balance shaft 31' - the gap between the inner wall of the retaining ring 312' and the outer wall of the balance shaft seat 32', thereby causing the bearing and the balance shaft 31' to wear failure, shortening the service life of the bearing and balance shaft 31'
