Electronic brake system for lightweight electric vehicles

Abstract

The invention discloses an electronic brake system for lightweight electric vehicles. The electronic brake system comprises an electronic brake device, a wheel speed detection device and a brake switch which are connected with a brake controller; the electronic brake device at least composing of brake motors and brake pads is simple and convenient in overall structure, and the weight of the complete vehicle is favorably reduced; the wheel speed detection device comprises code wheels mounted on wheels; the brake switch is composed of angle transducers installed on brake handlebars. Breaking speed is determined by the brake controller according to the size of an angle numerical signal, and a corresponding control signal is output to the brake motors so that the brake motors can output suitable braking torque to control the brake pads to complete braking; meanwhile, the rotate speed of the wheels is detected in real time through the code wheels of the corresponding wheels, the braking torque of the wheels can be automatically adjusted through the brake controller according to the rotate speed, and constant braking of all the wheels is sustained; compared with a traditional manual brake system, the electronic brake system can effectively avoid side-turning hazards.

Description

technical field [0001] The invention relates to an automatic regulation braking system of a lightweight electric vehicle. Background technique [0002] With the requirements of energy saving and emission reduction, as well as the demand for "last mile" vehicles, lightweight electric drive vehicles are becoming more and more popular. This type of lightweight vehicles that are easy to carry and easy to use, or in other words, the use of lightweight electric vehicles The market demand is very large. [0003] The brake system is divided into drum brakes and disc brakes. The drum brake is composed of a brake device, a brake pad and a tympanum. When braking, the brake device is activated, and a force is applied to the two half-moon-shaped brake shoes to make it press against the inner wall of the tympanum, and the brake drum is prevented from rotating by friction. So as to achieve the braking effect. [0004] At present, the existing braking methods on the market are divided in...

Problems solved by technology

However, this kind of brake system has a huge structure and the brakes are very sudden, which is easy to make passengers feel uncomfortable, so it is not suitable for the brake system of lightweight electric vehicles.

Manual brakes are often used in the brakes of bicycles. The operator manually controls the brakes. If the operation is not done properly at high speeds, only one wheel is braked and rollover is likely to occur.
