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
The present invention relates to vehicle and engineering field, specifically a kind of lightweight balance shaft assembly.
Background technology
Former balance shaft assembly transmission shaft insufficient space, complete vehicle weight is laid particular stress on, and is mainly reflected in several aspect:
1, adopt general connection shaft structure, to meet load-carrying capacity limited, transmission shaft motion space is narrow and small;
2, adopt general connection shaft structure, balance shaft assembly heavier-weight, complete-vehicle oil consumption is high, and cost is high, can not meet existing lightweight Market Situation.
As shown in Figure 1: the cutaway view of the former balance shaft assembly of Fig. 1, comprise left socle 1 and right support 2, the erection above of left socle 1 and right support 2 has vehicle frame 3, be provided with adapter shaft 6 between, be provided with left half axle 4 and right axle shaft 5 a kind of balance shaft assembly of formation jointly respectively in its outer both sides, this balance shaft assembly in use structure is comparatively complicated, simultaneously because the use of adapter shaft too increases weight, under weight-saving requires, this balance shaft assembly just seems heavy.
Summary of the invention
The present invention seeks to the bright one that provides lightweight, simply non-maintaining lightweight balance shaft assembly is installed.
Technical scheme of the present invention is for this reason, a kind of lightweight balance shaft assembly, comprise vehicle frame, it is characterized in that: vehicle frame two outside be erected between left A-frame, right A-frame respectively, the outside of left A-frame, right A-frame is provided with left bearing hub assembly, right bearing hub assembly.
Further improvement is: the left half axle in left bearing hub assembly, right bearing hub assembly, the outer ring of right axle shaft are respectively equipped with left bearing hub, right bearing hub, and left bearing hub assembly, right bearing hub assembly are outer to be fixed by left and right end cap; Be respectively equipped with left oil seal ring, right oil seal ring outside left bearing hub assembly, right bearing hub assembly, and be respectively equipped with oil sealing inside left bearing hub assembly, right bearing hub assembly, make it to form double sealing structure.
Further improvement is: the left half axle outside left bearing hub, right bearing hub, right axle shaft are also respectively equipped with non-metallic bushings, make it to become self-lubricating structure.
Beneficial effect:
Vehicle frame of the present invention two outside be erected at respectively between left A-frame, right A-frame, there is stability, make vehicle frame while taking on load-bearing, also take the effect of left and right pulling force, ensure that weight-saving is implemented.Make balance shaft assembly at increase transmission shaft motion space, remove former left and right connection shaft connection mode, be adjusted to split type connection, balance shaft assembly carrying and front and back drive axle propulsive effort directly act on vehicle frame by A-frame, without the need to installing Connection Block by crossbeam transmission and the extra propelling rod that increases; Effective minimizing balance shaft assembly weight, supporting structure is adjusted, former for semiaxis cantilever support is adjusted to left and right double bracing form, thus effectively alleviate semiaxis weight, former bearing hub is installed on bottom leaf spring and is raised to leaf spring top, improve bearing hub stressed thus alleviate bearing hub weight.
The installation of non-metallic bushings, bearing hub is rotated can effectively self-lubricating, avoids periodical maintenance charging-up lubricant oil, easy to maintenance.
The enforcement of double oil seal, can ensure that the lubrication of non-metallic bushings can be permanently effective, ensures non-metallic bushings service life.
Structure of the present invention is simple, cost is low, lightweight, simplify the structure, reduce manufacture difficulty.
