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
[0066] 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.
[0067] 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.
[0068] Such as Figure 1 to Figure 5 As shown, the present disclosure provides a brake-by-wire system, which can be used for braking vehicles, such as passenger cars, commercial vehicles, trains, subways, light rails, trams, and the like. The brake-by-wire system includes a disc brake 100 and a cable operating device 300. The disc brake 100 includes a brake caliper body 101, a first brake block 102, a brake disc 103, a piston 104, a first motor, and a rotating ring 105. ...

The present disclosure relates to a brake-by-wire system and vehicle comprising disc brakes and a cable operator, a first motor for driving a piston towards a first brake pad and causing the first brake pad to press against a brake disc , the thrust assembly is threadedly connected to the rotating ring, and the rotating ring drives the thrust assembly to move along the axis of the rotating ring; the cable manipulation device includes a second motor, a clutch, and a lead screw mechanism, and the lead screw mechanism includes a first lead screw and a first lead screw sleeved on the first lead screw. The nut on the rod, the thread lead angle of the lead screw mechanism is greater than its self-locking angle, one end of the cable is connected with the rotating ring, and the other end is connected with the first lead screw, and the clutch is used to engage or disconnect between the second motor and the nut When the clutch is in the engaged state, the second motor drives the nut to rotate, so that the first lead screw pulls the rotating ring through the cable to overcome the elastic force of the return spring and rotates. When the clutch is in the disengaged state, the rotating ring is reset Rotate and reset under the elastic force of the spring.
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...
