Problems solved by technology

The brake-by-wire system has the advantages of simple structure, fast braking dynamic response and good braking comfort performance. However, once the control circuit of the brake-by-wire system fails, the brake-by-wire system will lose its braking ability and its reliability is low.

Embodiment Construction

[0071] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0072] In the present disclosure, in the absence of a contrary statement, the used orientation words such as "inside and outside" refer to the inside and outside of the specific structural outline, and the used terms such as "first" or "second" only refer to It is to distinguish one element from another, and does not have sequence or importance.

[0073] Such as Figure 1 to Figure 5 As shown, the present disclosure provides a brake-by-wire system. The brake-by-wire system may include a disc brake 100 and a cable operating device 300. The disc brake 100 may include a brake caliper body 101, a first brake shoe 102, a brake The moving disc 103, the rotating r...

Abstract

The present disclosure relates to a brake-by-wire system and a vehicle. The brake-by-wire system includes a disc brake and a cable control device. The disc brake includes a brake caliper body, a first brake block, a brake disc, a rotating ring, a thrust assembly, a return spring and a cable, and the thrust assembly is threaded. For the rotating ring, when the rotating ring rotates, the rotating ring drives the thrust assembly to move along the axis of the rotating ring; the cable control device includes a motor, a clutch and a screw mechanism, and the screw mechanism includes a first screw and a nut. The two ends are respectively connected with the rotating ring and the first lead screw. When the clutch is engaged, the motor drives the nut to rotate, so that the first lead screw moves along the axis of the nut, and the rotating ring is pulled by the cable to rotate, so that the thrust assembly deviates from The first brake block moves, and when the clutch is in a disengaged state, the rotating ring rotates and resets under the elastic force of the return spring, pushing the first brake block to press the brake disc.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle braking, and in particular, to a brake-by-wire brake system and a vehicle using the brake-by-wire system. Background technique [0002] In the traditional hydraulic or pneumatic braking system, there are obvious disadvantages such as complex gas-liquid pipeline, difficult maintenance, complex layout structure, slow dynamic response of braking, and low braking comfort performance. For example, in the hydraulic braking system, when the anti-lock braking system operates, the brake pedal will produce rebound vibration, which affects the braking comfort performance. For another example, the conventional hydraulic braking system has not only complex structure and assembly but also large volume due to the use of larger vacuum brake booster, brake master cylinder, oil reservoir and other conventional hydraulic braking system components. 1. The problem of difficult maintenance, and because the sy...
