Vehicle balance suspension with balance axles and brackets integrated into one

Abstract

In order to reduce the weight of a vehicle balance suspension, ensure the strength and improve the load condition, the invention provides the vehicle balance suspension with balance axles and brackets integrated into one. A left balance axle functional part is integrally cast and molded at a left bracket to form a left bracket and axle integrated part. A right balance axle functional part is integrally cast and molded at a right bracket to form a right bracket and axle integrated part. Balance axle bushes are integral rubber bushes which are integrally molded and an outer limit annular boss and an inner limit annular boss are respectively arranged at the outer circumference and the inner hole of each of the rubber bushes. Each of the integral rubber bush is provided with an axial opening on the circumference, and the integral rubber bushes are unfolded through the axial openings for assembling. Lower thrust lever mounting parts of the left bracket and axle integrated part and the right bracket and axle integrated part are connected through a reinforcing connection plate. The inner limit annular bosses of the balance axle bushes are matched with fixing grooves on the left balance axle functional part and the right balance axle functional part. The outer limit annular bosses of the balance axle bushes are matched with the fixing grooves on balance hubs.

Description

technical field [0001] The invention relates to an automobile balance suspension, which is applied to a load-carrying double rear axle automobile. Background technique [0002] At present, the balance shaft bracket and the balance shaft split structure used in ordinary balance suspensions are connected to the balance shaft bracket and the balance hub through the balance shaft. There are many connecting parts, the product is heavy, and the structure is complicated; the balance shaft bushing used is a steel bimetal bushing. The sleeve has no cushioning performance, and has high requirements on the strength of the balance shaft and balance hub, and the steel bimetallic bushing is prematurely worn due to poor lubrication. Contents of the invention [0003] In order to reduce the weight of the automobile balance suspension, ensure the strength, and improve the stress condition, the present invention proposes an automobile balance suspension integrated with a balance shaft and a...
