Integrated power system with steering function, power assembly and vehicle

Abstract

The invention provides an integrated power system with the steering function, a power assembly and a vehicle. The power system comprises a frame, a power assembly, a wheel assembly and a retainer. The power assembly is respectively connected with the frame and the retainer and provides power for the action of the wheel assembly; the wheel assembly is connected with the retainer; wherein the power assembly realizes the steering adjustment of the wheel assembly by adjusting the orientation of the retainer. According to the integrated power system with the steering function, the power assembly and the vehicle, the hub motor and the suspension system are integrated, the mass of the hub motor and the suspension system is completely converted into sprung mass, the unsprung mass brought by the motor and a transmission system is effectively reduced, the chassis space is saved. Meanwhile, driving, braking and steering are combined into a whole, and the power system is convenient to use. The modular level of the chassis walking system can be effectively improved, the chassis space is saved, and the chassis walking system has great advantages when being applied to buses and logistics vehicles with low chassis height requirements.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an integrated power system with a steering function, a power assembly and a vehicle. Background technique [0002] The size of the car's unsprung mass (unsprung mass) affects the driving safety and comfort of the car. At present, the wheel-side and wheel-hub electric power system represented by electric wheels has become a popular vehicle due to its simple power system and vehicle structure, high transmission efficiency, and the torque of each driving wheel can be independently controlled, which is conducive to improving the driving performance under harsh road conditions. Research hotspots. However, due to the fixed connection between the motor and the drive wheel, the unsprung mass of the automobile will be increased. Contents of the invention [0003] The present invention proposes an integrated power system with steering function, which is used to solve the defects in th...

AI Technical Summary

Problems solved by technology

[0004] The present invention also proposes a power assembly, which is used to solve the defects in the prior art that the in-wheel motor and the driving wheel are fixedly connected, which will increase the unsprung mass of the car, thereby affecting the driving safety and ride comfort of the car. It is integrated with the suspension system and completely converts its mass into sprung mass, effectively reducing the unsprung mass brought by the motor and transmission system, and saving chassis space. At the same time, it combines driving, braking, and steering into one body, which can Effectively improve the modularization level of the chassis walking system, save chassis space, and have great advantages when applied to buses and logistics vehicles that require a low chassis height
