Description

Technical Field

[0001] The utility model relates to the technical field of brake equipment for electric tricycles, in particular to a brake system for electric tricycles. Background Art

[0002] The information disclosed in the background technology of the present invention is only intended to increase the understanding of the overall background of the present invention, and shall not necessarily be regarded as an admission or suggestion in any form that the information constitutes the prior art already known to those skilled in the art.

[0003] At present, most electric tricycles use handbrakes to control the front wheel brakes, footbrakes to control the rear wheel brakes, and parking brakes associated with the rear wheel brakes are also provided. Generally, using the rear wheel footbrake alone will cause the vehicle to be unstable when braking suddenly, and it is easy to drift, because the rear wheel brakes too hard and the front wheel lacks sufficient braking force, which affects the vehicle's handling and safety. Conversely, using only the handbrake to control the front wheel brakes may also cause the front end of the vehicle to sink, affecting driving stability. The braking operation using both hands and feet increases the driver's reaction time and difficulty of operation. Especially in an emergency, the driver may not be able to quickly and effectively operate the handbrake and footbrake at the same time due to nervousness or physical limitations. Especially for older people, their reaction speed and physical strength are poor, which can cause a rush, resulting in delayed braking or poor braking effect.

[0004] Therefore, it is necessary to study a brake system for an electric vehicle in which the front and rear wheels can be braked simultaneously. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a braking system for an electric tricycle, which aims to reduce the difficulty of driving the electric tricycle, distribute the braking force more evenly, reduce the braking distance, and improve safety.
