Problems solved by technology

[0002] At present, the design and production of trailer axles in the market are relatively chaotic. The manufacturers of each trailer axle make appropriate changes to the relevant parts according to their own actual conditions, resulting in the same trailer axle, the configuration of its related parts, Parameters vary and do not meet standard requirements
The design is very conservative, using the parts of the large-tonnage trailer axle, changing the joint on the hub and the rim to the size of the small-tonnage trailer axle, the total weight is roughly the same as that of the large-tonnage trailer axle, so that the sales price is difficult The reduction is a phenomenon of "big horses and small carts", which cannot optimize the design and make rational use of resources

Abstract

The invention discloses a trailer bridge assembly which is characterized in that hubs are connected and supported at two ends of a spindle through an inner rolling bearing and an outer rolling bearing. A brake hub is fixed on the periphery of each hub through a hub bolt. A brake shoe assembly is fixedly connected inside each brake hub through a brake shoe shaft and a brake camshaft. A roller shaft at one end of a brake shoe is matched with an S-shaped head on the brake camshaft. An adjusting arm assembly is connected to the other end of the brake camshaft. A brake push rod on the adjusting arm assembly is connected with an air chamber support fixed on the spindle through a tension spring. The trailer bridge assembly meets standard requirements, lowers production cost and guarantees product quality.

Description

technical field [0001] The invention relates to an automobile part, in particular to a trailer axle assembly. Background technique [0002] At present, the design and production of trailer axles in the market are relatively chaotic. The manufacturers of each trailer axle make appropriate changes to the relevant parts according to their own actual conditions, resulting in the same trailer axle, the configuration of its related parts, The parameters vary and do not meet the standard requirements. The design is very conservative, using the parts of the large-tonnage trailer axle, changing the joint on the hub and the rim to the size of the small-tonnage trailer axle, the total weight is roughly the same as that of the large-tonnage trailer axle, so that the sales price is difficult The reduction is a phenomenon of "big horses and small carts", which cannot optimize the design and make rational use of resources. Contents of the invention [0003] The object of the presen...
