Problems solved by technology

[0005] The purpose of the present invention is to provide a double-wheel-side motor bridge and a new energy vehicle equipped with a leaf spring suspension, so as to solve the problem that the structure of the drive system of the new energy vehicle in the prior art is connected by a central motor or a gearbox through a transmission shaft. The rear axle is poor, the transmission efficiency is poor, and the system constitutes a complicated problem

Abstract

The invention relates to the field of automobile power systems and discloses a double-rim motor axle used for erecting a plate spring suspension and a new-energy automobile. The double-rim motor axlecomprises a drive axle housing, a left motor, a right motor, a left speed reduction mechanism, a right speed reduction mechanism, a left plate spring installation seat and a right plate spring installation seat. The left motor and the right motor are close to the center position of the drive axle housing, the left speed reduction mechanism is connected with the left motor, the right speed reduction mechanism is connected with the right motor, the left plate spring installation seat is fixed to the left speed reduction mechanism, and the right plate spring installation seat is fixed to the right speed reduction mechanism. The double-rim motor axle is simple and compact in structure; the gravity center is lowered, and the vehicle traveling stability is improved; a transmission chain is short, energy consumption is reduced, and economical efficiency is improved; the vehicle traveling dynamics performance is improved; the steering radius is reduced, and steering flexibility and convenienceare improved; and braking energy can be recycled.

Description

technical field [0001] The invention relates to the field of automobile power systems, in particular to a double-wheel motor bridge equipped with a leaf spring suspension and a new energy vehicle. Background technique [0002] The power system of new energy vehicles can be divided into three stages of technological development. The first stage is centralized drive technology, the second stage is wheel motor technology, and the third stage is wheel hub motor technology known as the ultimate solution. At present, the new energy vehicle market at home and abroad is dominated by centralized drive. The wheel-side motor technology is commonly used in passenger cars or commercial vehicles, while the in-wheel motor technology cannot be widely used in electric vehicles due to the difficulty in design. [0003] Most of the new energy drive systems on the market now have a structure in which a central motor is connected to a traditional rear axle through a transmission shaft, which has...
