Lightweight electric four-wheeler

Abstract

The invention relates to the technical field of electric vehicles, particularly to a lightweight electric four-wheeler. The lightweight electric four-wheeler comprises a vehicle frame, four wheels, a steering system, a damping system, a driving motor, a battery set and a motor controller, wherein a differential mechanism is mounted on a back transmission shaft of the two back wheels, and the driving motor is connected with the differential mechanism; the damping system comprises four arc-shaped steel plates, one end of each steel plate is fixed at the bottom of the vehicle frame, and the other end of each steel plate is locked on a front transmission shaft or the back transmission shaft through steel wires separately. The lightweight electric four-wheeler is simple in structure and convenient to use. As the differential mechanism is mounted, the electric vehicle can turn smoothly; as the battery set is horizontally laid in a battery box in the middle of the vehicle frame, , the battery set can be conveniently replaced, , and the stress on the vehicle frame is uniform, and thus the stability of the vehicle is increased; as the damping system of the lightweight electric four-wheeler adopts the steel plates with elastic deformation, the production cost of enterprises is saved, and the damping system can be mounted rapidly and conveniently.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a portable electric four-wheel vehicle. Background technique [0002] Present portable electric vehicles include two-wheeled electric bicycles, two-wheeled electric motorcycles and electric tricycles. Relevant to this application is a portable electric tricycle. The structure of a portable electric tricycle is to include a frame body, a front wheel, a front fork mounted on the front wheel, a steering handlebar, two rear wheels, a seat, and a power system composed of a battery, a DC motor, and a brake. systems and electronic control systems, etc. The disadvantage of this portable electric tricycle is that the body is unstable, there is no carport, and it cannot shelter from wind and rain; the battery energy is limited, and the continuous driving distance at a time is small; the power is insufficient, and the climbing ability is small.

AI Technical Summary

Problems solved by technology

This technology is mainly improved on the technology of the tricycle, and several driving modes are disclosed, but since the two rear wheels are driven at the same speed, when the electric four-wheel vehicle is turning, the rotational speed of the steering wheel is the same. Under the condition of the same line speed, the two wheels run at the same speed, and the electric four-wheel vehicle will eat tires when turning, or the four-wheel vehicle will lose control when the speed is relatively fast; Vibration measures, users will feel uncomfortable when riding on bumpy roads. Although there are many springs used as shock absorbers in the market, spring shock absorbers need to be installed on all four wheels, which is cumbersome to assemble and expensive.
