Wheel edge drive assembly based on sprung mass

Abstract

The invention relates to a wheel edge drive assembly based on sprung mass. The wheel edge drive assembly comprises a distributed drive system, axle shafts, a steering system and a suspension system; the distributed drive system comprises two motors and two transmissions, the two motors are arranged in a left-right symmetric manner and are fixedly integrated and mounted on a frame, the two transmissions are arranged in a left-right symmetric manner and are fixedly integrated and mounted on the frame, and the motors are connected with the input ends of the transmissions; one ends of the axle shafts are connected to rims, and the other ends of the axle shafts are connected to the output ends of the transmissions; the steering system includes a steering machine fixedly mounted on the frame, and the steering machine is in transmission connection with the rims to control steering of the rims; and the suspension system comprises an upper arm A, a lower arm A and a main pin, one end of the upper arm A is connected to the frame, the other end of the upper arm A is connected to the upper end of the main pin, one end of the lower arm A is connected to the frame, and the other end of the lowerarm A is connected to the lower end of the main pin, and the main pin is connected the rims. According to the wheel edge drive assembly, through optimal design, the drive assembly is improved to be arranged on a spring, the unsprung mass is greatly optimized, the operation stability and comfort of a whole vehicle are improved, the impact of the road surface is transmitted to the drive assembly through the action of the suspension system, the reliability is improved, and the whole vehicle dynamics is further improved.

Description

technical field [0001] The present invention relates, in particular, to a sprung mass-based wheel drive assembly. Background technique [0002] At present, most of the wheel drive assemblies are arranged at the unsprung wheel end, which has poor handling stability and comfort, and the existing unsprung wheel drive solutions occupy a large space around the wheel, and the tire steering space is limited. , and most of the existing wheel-side drive schemes are motors matched with reducer mechanisms, and the power performance is slightly poor. [0003] Although with the advancement of technology, there are already some schemes that arrange the drive assembly as a sprung type, and some wheel drive schemes use motors to match the transmission, but the optimization performance is not good, and it cannot be matched with the vehicle suspension, so it is always Unable to achieve desired results.
