[0004] Patent authorization announcement number is the Chinese invention patent of CN2853471Y. The buffer device is arranged on the shaft of the driving wheel of the motor vehicle. During emergency braking, the pin shaft that closes the force component groove is opened, so that the wheel shaft slides down along the force component groove, thereby decomposing the forward sprint force into downward and upward forces, reducing the forward inertial force of the motor vehicle, although shortened to a certain extent The distance that the vehicle rushes forward after emergency braking, but it cannot achieve fast and smooth braking during emergency braking

Abstract

The invention relates to a brake device. The brake device comprises a pressurization brake mechanism and a controller controlling the work of the pressurization brake mechanism, wherein the pressurization brake mechanism comprises a roller box arranged on a wheel axle, the roller box is pressed on the wheel axle by an elastic component, a transmission sleeve arranged on the wheel axle through a bearing is arranged in the roller box, and a topmost layer of roller serving as a bearing wheel, multiple layers of rollers performing force transmission functions and a bottommost layer of roller serving as a speed variable wheel set are sequentially arranged above the transmission sleeve from top to bottom, wherein the axial directions of all the layers of rollers are consistent with that of the wheel axle. The brake device acts on the wheel axle and brakes a vehicle through rolling friction force, so that an brake impact on the vehicle during emergency brake can be reduced, the forward inertia force of the vehicle can be quickly reduced, rapid brake is realized, and the safety of people in the vehicle during emergency brake are improved.

Description

technical field [0001] The invention relates to a braking device, in particular to an emergency braking device. Background technique [0002] At present, various commonly used brake devices mainly use drum brakes and disc brakes. Drum brakes are equipped with two semicircular brake pads in the wheel hub, and the brake pads and the wheel hub are pushed by the piston of the sub-pump using the principle of leverage. Friction occurs when the inner surface contacts to produce braking; disc brakes are equipped with brake pads on both sides of the brake disc driven by the wheel, and the brake pads are pushed by the sub-cylinder piston to clamp the brake disc on both sides to produce braking. In the above two braking methods, the brake pads and the wheel hub or brake disc generate a large braking force through sliding friction. When the vehicle is running at low speed, it can brake safely, but when driving at high speed, emergency braking is required in case of emergency. At this ...
