Abstract

The invention provides a battery electric vehicle for the disabled. According to the technical scheme, a supporting frame and a suspension axle are connected through two sets of main springs, so that a damping effect is guaranteed in the vertical direction; and meanwhile, in order to solve the problem that a battery electric vehicle low in self-weight generates severe lateral deviation when jolting, oblique hydraulic cylinders are arranged on the edges of the supporting frame and the edges of the suspension axle, and therefore the damping effect is improved. In addition, a horizontal tray is welded between a chassis and the suspension axle, the tray is surrounded by protruding portions and connecting rods, and thus the tray can be used for fixing a battery pack due to the structure. In this mode, the large-weight battery pack is moved forwards to the vehicle head, the self-weight of the vehicle head is increased, and therefore the dragging stability of an engine is improved, and meanwhile vibration and jolting are further relieved. According to the battery electric vehicle, the damping performance of the battery electric vehicle is greatly improved due to the creative design of a front suspension assembly, and the battery electric vehicle is driven more stably and is particularly suitable for the disabled.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle for disabled persons. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. Pure electric vehicles, compared with fuel vehicles, the main difference (difference) lies in the four major components, drive motor, speed controller, power battery, and on-board charger. Electric vehicles use fuel cells as the power source. The chemical reaction process of the battery will not produce harmful products, so the pollution of electric vehicles is extremely small. Since the energy conversion efficiency of the battery is 2 to 3 times higher than...
