REAR-MOUNTED AND REAR-DRIVE CHASSIS FOR ULTRA-MICRO LOW-SPEED PURE ELECTRIC PASSENGER CAR

摘要

A rear-mounted and rear-drive chassis for an ultra-micro low-speed pure electric passenger car pertains to the technical field of a chassis for an electric vehicle, and includes a frame body (1), a front axle and a rear axle both of which are disposed on the frame body (1). It is characterized in that: front wheels are provided at both ends of said front axle; said rear axle is a drive axle; two motors are symmetrically disposed on the rear axle, one ends of which are connected, and the other ends of which are respectively provided with a transmission; the output end of the transmission drives and connects rear wheels. The present invention has a compact structure, a reasonable design and advantageous effects as follows: 1) novel front and rear suspension designs, both using the designs of simplified linkages and lightweight parts; 2) a lightweight braking system, the parts of which mostly use lightweight materials and small-size designs; 3) a lightweight chassis platform. The weight of the whole chassis system is controlled to be under 150 kg, thus providing a common chassis platform for the development of the ultra-micro pure electric passenger car; 4) motors are symmetrically disposed on the real axle, thus obtaining a short drive line, high efficiency and strong power.
