Embodiment Construction

[0046] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

[0047] At present, the brake-by-wire system is a brand-new braking mechanism, which is an innovation in the function and triggering device of the braking drive mechanism. The brake-by-wire system cancels the traditional hydraulic brake system, uses the motor to provide braking energy, transmits the driver's braking intention with electrical signals, and the actuator is an electromechanical brake actuator. When the vehicle is braking, the driver depresses the brake pedal, the brake pedal ...

Abstract

The invention discloses a disc brake and a vehicle with the disc brake. The disc brake comprises a caliper body, a linear motor, an electric locking component and a first brake lining; the linear motor comprises a primary structure and a secondary structure, and the primary structure is fixedly connected with the caliper body; the primary structure is provided with a first motor shaft; the electric locking component is structured for locking or releasing the first motor shaft selectively; and the first motor shaft is applicable for pushing the first brake lining, and the first brake lining canbe driven by the linear motor to move toward a brake disc fixedly arranged on a wheel when the first motor shaft is released. In this way, by adopting the mechanical electronic disc brake, external connection of a hydraulic brake control component is not required; and the disc brake is not only compact in structure and convenient in arrangement, but also higher in brake response speed and more flexible in response.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a disc brake and a vehicle having the same. Background technique [0002] In the related art, air pressure or hydraulic brake pipelines are mostly used in the brakes of vehicles. The quality of the vehicle is high, the braking response is delayed, the braking efficiency is low, and the hydraulic oil needs to be replaced regularly. At the same time, there is a risk of hydraulic oil leakage, which is not conducive to Environmental friendly. When the brake is damaged, it is inconvenient for maintenance and difficult to disassemble. The brake pedal produces rebound vibrations during vehicle braking. Moreover, the above-mentioned brake is not suitable for the control-by-wire system, so it is urgent to design a disc brake suitable for the control-by-wire system. SUMMARY OF THE INVENTION [0003] The present invention aims to solve one of the above-mentioned technical...
