Lightweight balance shaft assembly

Abstract

The invention relates to a lightweight balance shaft assembly. The two edges of a vehicle frame are erected between a left triangular support and a right triangular support. The outer side of the left triangular support and the outer side of the right triangular support are provided with a left bearing hub assembly and a right bearing hub assembly. An outer ring of a left half shaft in the left bearing hub assembly and an outer ring of a right half shaft in the right bearing hub assembly are provided with a left bearing hub and a right bearing hub respectively. The outer side of the left bearing hub assembly and the outer side of the right bearing hub assembly are fixed through a left end cover and a right end cover respectively. The mode that double sealing is conducted on the inner side and outer side of oil seal and left and right sealing rings is adopted for sealing of the left bearing hub assembly and the right bearing hub assembly. The left half shaft outside the left bearing hub and the right half shaft outside the right bearing hub are further provided with nonmetal linings respectively to form a self-lubricating structure. The lightweight balance shaft assembly has stability and guarantees lightweight implementation so that the transmission shaft movement space can be increased, the lightweight balance shaft assembly is simple in structure, low in cost and light in weight, the structure is simplified, and the manufacturing difficulty is lowered.

Description

technical field [0001] The invention relates to the field of vehicles and engineering, in particular to a lightweight balance shaft assembly. Background technique [0002] The space of the drive shaft of the original balance shaft assembly is insufficient, and the weight of the whole vehicle is heavy, which is mainly reflected in several aspects: [0003] 1. Adopt the universal connecting shaft structure, which meets the limited carrying capacity and the narrow movement space of the transmission shaft; [0004] 2. Adopting a common connecting shaft structure, the weight of the balance shaft assembly is relatively heavy, the fuel consumption of the whole vehicle is high, and the cost is high, which cannot meet the current lightweight market situation. [0005] Such as figure 1 Shown: figure 1 The cross-sectional view of the original balance shaft assembly, including the left bracket 1 and the right bracket 2, the left bracket 1 and the right bracket 2 are set up with a veh...
