Problems solved by technology

[0005] The planetary reduction mechanism of the existing double-stage reduction drive axle mostly adopts a spur gear structure. Under the circumstances that the structural size cannot be increased, the same power is transmitted, and the number of planetary gears is the same, the planetary reducer has a limited speed ratio range, a large structural weight, and Insufficiencies such as limited carrying capacity are important factors that limit the carrying capacity and performance of the vehicle

Abstract

The invention discloses a planetary reducing structure of a bevel wheel of a steering drive axle. The structure comprises a thrust bearing(18), a spring (17), a bell-shaped hub (1), a planetary bracket (27), a thrust washer (28), a helical tooth gear ring bracket (26), a kingpin (4), a space ring (2), a fixed steel wire ring spring (6), an adjusting pad (11), a retainer ring (13), a helical toothsun wheel (21), a helical planetary gear (3), a helical internal tooth gear ring (5) and a helical tooth gear ring bracket (26). A straight tooth planetary reducing mechanism is optimized, and meanwhile, a steering function is added to the helical tooth planetary reducing mechanism, so that the axial fore is overcome effectively. Meanwhile, the axial force is converted into a force of rolling friction effectively, so that the power loss is reduced, and furthermore, the helical planetary reducing mechanism of the drive axle with the steering function is additionally arranged.

Description

technical field [0001] The invention belongs to the field of automobile steering drive axles, and in particular relates to a helical gear planetary reduction structure of a drive axle. Background technique [0002] In some important application areas, with the development of the transportation industry, heavy-duty vehicles and special vehicles have higher and higher load-carrying capacity on drive axles and steering drive axles, and require more and more speed ratios. The demand for high load capacity and high speed ratio of drive axle is more and more urgent. [0003] In heavy-duty vehicles and special vehicles, the drive axle often adopts a double-stage reduction structure to obtain a larger transmission ratio. The planetary reduction mechanism of the bridge is the main factor that affects the speed ratio and bearing capacity of the drive axle, that is, it affects the bearing capacity and transmission capacity of the entire bridge. [0004] While ensuring the normal oper...
