Grade braking type ceramic base brake pad system

Abstract

The invention discloses a grade braking type ceramic base brake pad system, and relates to the technical field of ceramic base brake pads. According to the system, ordinary brake strength can be adjusted and set freely by a user. The grade braking type ceramic base brake pad system comprises an emergency brake ceramic base friction plate which is fixed at the left end of a steel plate and an ordinary brake ceramic base friction plate which is arranged in a clamping groove in the right portion of the steel plate in a telescopic mode and is controlled by an ordinary brake strength adjusting device. A hydraulic input device is used for pressing a hydraulic agent in a hydraulic agent storage box into a plicated liquid tire band to enable the user to adjust and set the ordinary brake strength freely. A double-pad brake structure with the ordinary brake ceramic base friction plate and the emergency brake ceramic base friction plate being combined is adopted; when a vehicle brakes, only the ordinary brake ceramic base friction plate is used for braking in the ordinary braking condition; the ordinary brake ceramic base friction plate and the emergency brake ceramic base friction plate are used for braking together in the emergency braking condition.

Description

technical field [0001] The invention relates to the technical field of ceramic-based brake pads, in particular to a hierarchical braking type ceramic-based brake pad system. Background technique [0002] At present, the friction force between the ceramic-based friction plate and the brake drum depends entirely on the strength of the driver's depressing the brakes, and the brakes are all based on the driver's feeling. In this way, if only conventional braking is required, driving The driver stepped on the brakes too hard, resulting in sudden braking. Sudden braking not only wears heavily on the vehicle, but also may cause collision damage to the occupants in the vehicle; and the existing ceramic-based friction plates adopt a single-piece brake structure, resulting Users have less freedom to choose the braking effect of ceramic-based friction discs. [0003] The working principle of the brake is mainly from friction, using the friction between the brake pad and the brake disc...

Problems solved by technology

[0007] The present invention aims to solve the problem that the friction force between the existing ceramic-based friction plate and the brake drum depends entirely on the strength of the driver's stepping on the brakes, and the brakes are all based on the driver's feeling. In the case that the driver depresses the brake too hard, a sudden brake occurs. The sudden brake not only wears the vehicle more, but also may cause collision damage to the occupants; and the existing ceramic-based friction plate adopts a single Disc brake structure, leading to the lack of freedom for users to choose the braking effect of ceramic-based friction discs. To provide a graded braking ceramic-based brake pad system, the gap between conventional brake ceramic-based friction discs and brake drums is provided. The maximum friction force between them can be adjusted. When braking under normal braking conditions, it can be realized as long as the friction force generated by the driver stepping on the brake is less than the maximum friction force between the conventional brake ceramic-based friction plate and the brake drum. There will be no sudden braking, conventional braking will cause less wear and tear on the vehicle, and will not cause collision damage to the occupants; and the combination of conventional braking ceramic-based friction plates and emergency braking ceramic-based friction plates is adopted Double-disc brake structure, when braking, if the brake is under normal braking, only the conventional brake ceramic-based friction plate is used for braking; if the brake is under emergency braking, the conventional brake ceramic-based friction plate and The emergency braking ceramic-based friction disc brakes together, and the conventional braking strength of the conventional braking ceramic-based friction disc can be freely adjusted and set by the user
