Problems solved by technology

The brake-by-wire system has the advantages of simple structure, quick braking dynamic response and good braking comfort performance. However, in the existing brake-by-wire system, usually only one motor is used to provide braking force. Once the motor fails, the entire brake-by-wire system will The system will lose its braking ability, and its reliability and safety will be lower

Embodiment Construction

[0057]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.

[0058] In the present disclosure, the orientation words such as "inside and outside" used refer to the inside and outside of the outline of the corresponding part unless stated otherwise.

[0059] Such as Figure 1 to Figure 3 As shown, the present disclosure provides a disc brake, including a brake caliper body 1, a first brake block 11, a brake disc 12, a transmission mechanism, a rotating motor 2 and a linear motor 3, the first brake block 11 and the brake disc. The moving disc 12 is arranged in the brake caliper body 1, and the transmission mechanism is used to convert the input rotational torque into a linear torque output. Wherein, the rotary motor 2 c...

Abstract

The invention relates to a disc brake, a brake-by-wire system and a vehicle. The brake comprises a brake caliper body, a first brake block, a brake disc, a transmission mechanism, a rotating motor anda linear motor, wherein the first brake block and the brake disc are arranged in the brake caliper body, the transmission mechanism is used for converting input rotating torque into linear torque tobe output, the rotating motor drives the first brake block to move towards the brake disc through the transmission mechanism, and the linear motor is used for pushing the first brake block to move sothat the first brake block can press the brake disc. By means of the technical scheme, one of the rotating motor and the linear motor can serve as a power source for traveling braking, and the other one can serve as a power source for emergency braking, so that even if any one of the rotating motor and the linear motor breaks down, the other one can normally provide a braking force to achieve braking, and thus reliability and safety performance of the brake system are effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle braking, and in particular, to a disc brake, a brake-by-wire system using the disc brake, 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 m...
