Abstract

A motor drive axle of a double-track vehicle comprises a drive motor, a differential planet set, a hub reduction gear, a steering motor, an electromagnetic brake, a center shell and a reduction bevel gear pair. The driving motor is arranged at the bottom in the center shell, the output ends of the two ends of the driving motor are connected to sun wheels of the differential planet sets, and a planet carrier of each differential planet set is connected with the hub reduction gear. A steering motor is arranged at the top of the center shell, an electromagnetic brake is arranged at the output end of the steering motor, the output end of the steering motor is connected with a speed reduction bevel gear pair, and each bevel gear is connected to outer gear rings of the two differential planet sets through gears. The planet carrier speed reduction and differential process is adopted, the whole structure is simple and small, and the steering problem of the double-track vehicle is well solved through the structure. The whole mechanical stability is high, and through braking of the electromagnetic brake, on the premise that straight movement is guaranteed, the slipping phenomenon in the straight movement process is well guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of motor drive axles, in particular to a motor drive axle of a double-track vehicle. Background technique

[0002] At present, the degree of research on the steering device of dual-track vehicles in my country is not enough. The research content is mostly about the parameter design, structure, and performance of the steering system, and there is not much involved in the drive steering system, especially the drive axle. The structure of the existing known drive axle does not take into account the overall stability, resulting in poor safety and stability. Contents of the invention

[0003] The object of the present invention is to provide a motor drive axle for a double crawler vehicle to solve the above problems.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A motor drive axle for a dual-track vehicle, including a drive motor, a differential...
