Problems solved by technology

[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, the brake pedal will rebound and vibrate when the anti-lock braking system operates, which affects the braking comfort performance
For another example, since the brake pedal mechanism is directly connected with the brake transmission device and the brake actuator, the impact force generated when the vehicle collides will be directly transmitted to the cab through the brake system, which seriously affects the safety performance of the car.
As another example, the conventional hydraulic braking system uses components of the conventional hydraulic braking system such as the vacuum brake booster, the brake master cylinder, and the oil reservoir that are relatively large in size, so it not only has complex structure and assembly, but also has a large volume. , Difficult maintenance, and because the system is equipped with hydraulic brake lines and brake fluid connected to the corresponding components, it is necessary to replace the hydraulic oil regularly and regularly check whether there is a problem of hydraulic oil leakage

Abstract

The invention relates to a disc brake and a vehicle. The disc brake comprises a brake caliper body, a first brake block, a driving braking unit and a parking braking unit, wherein the parking brakingunit comprises a parking motor, a parking screw rod mechanism, a lever mechanism and a push rod; the parking motor drives the push rod to axially move through the parking screw rod mechanism and the lever mechanism in sequence, so that the push rod is enabled to push the first brake block to move so as to compress the brake disc; and the lever mechanism is used for transmitting output force of theparking screw rod mechanism to the push rod. In the brake disclosed by the invention, the driving braking unit and the parking braking unit are arranged so that the brake can achieve two functions ofdriving braking and parking braking at the same time, the function integration level is high, the structure is compact, and the occupied space is small; and compared with hydraulic or pneumatic parking, the braking response is faster, and the safety is better; and in addition, by arranging the lever mechanism, the arrangement mode of all parts in the brake is more flexible, and the structure is more compact.

Description

technical field [0001] The present disclosure relates to the field of brakes, in particular, to a disc brake and a vehicle. 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, since the brake pedal mechanism is directly connected with the brake transmission device and the brake actuator, the impact force generated when the vehicle collides will be directly transmitted to the cab through the brake system, seriously affecting the safety performance of the car. As another example, the conventional hydraulic braking system has complex structure and assemb...
