Assembly type anti-lock brake disc

Abstract

The invention relates to the technical field of automobile brake discs, in particular to an assembly type anti-lock brake disc. The left end of a first brake disc is equipped with a second brake disc;during emergency braking, a brake clamp simultaneously brakes the first brake disc and the second brake disc; under action of the brake clamp, the second brake disc stops rotation; the brake effect of the brake clamp only acts on one surface of the first brake disc, so that the first brake disc does not stop rotation to have a lock phenomenon; the first brake disc continuously rotates to drive amovable disc to automatically move; after a second friction plate is in contact with the first brake disc, the movable disc reversely moves under action of two-way threads while a transient brake effect can be provided for the first brake disc; the movable disc moves back and forth, and intermittent brake effect can be generated on the second brake disc, so that wheels are prevented from being suddenly locked during emergency braking, and therefore, the problems that a car generates sideslip and the car loses direction manoeuverability as the wheels are suddenly locked during emergency brakingare solved.

Description

technical field [0001] The invention relates to the technical field of automobile brake discs, in particular to an assembled anti-lock brake disc. Background technique [0002] Locking is when the brake (whether disc or hub) clamps the tire, and the tire has no relative motion to the brake. In other words, the tire does not turn, and the car slides on the road like a brick; when the car brakes suddenly at a high speed on a wet or icy road, such dangerous situations are likely to occur : The rear of the car deviates from the direction of travel during the braking process. In severe cases, the car will turn around and the car will lose its directional stability. This phenomenon is called sideslip; another situation is that the driver controls the The driving direction of the car is lost, that is, the car loses the maneuverability of the direction. If braking on a curve, the car will slide out along the side of the road or break into the opposite lane. The reason for these da...

In other words, the tire does not turn, and the car slides on the road like a brick; when the car brakes suddenly at a high speed on a wet or icy road, such dangerous situations are likely to occur : The rear of the car deviates from the direction of travel during the braking process. In severe cases, the car will turn around and the car will lose its directional stability. This phenomenon is called sideslip; another situation is that the driver controls the The driving direction of the car is lost, that is, the car loses the maneuverability of the direction. If braking on a curve, the car will slide out along the side of the road or break into the opposite lane. The reason for these dangerous situations is that the wheels of the car are locked during the braking process. At this time, the movement of the wheels relative to the road is no longer rolling, but sliding, and the road acts on the side of the tires. Sliding friction force and longitudinal braking force become smaller, the more slippery the road surface, the more prone to wheel locking; at the same time, the higher the initial speed of the car braking, the greater the risk of wheel locking
