Antilock brake system

Abstract

The spot releasing antilock brake system consists of a brake body, a shaft combination penetrating the brake body, a driving wheel slide fitting the shaft combination, a spot release wheel on the driving wheel, a brake fork in the spot release site of the spot release wheel, contacting the rim and with a guide tube, and a spring outside the guide tube and between the brake body and the brake fork. The spot releasing antilock brake system is suitable for different kinds of small vehicles.

Description

Technical field: [0001] The invention relates to an actuating mechanism for a brake, in particular to a device configured on the brake for starting at a predetermined position. Background technique: [0002] Vehicles, especially small vehicles, such as bicycles, mopeds and small motorcycles, usually use the power of the human hand as the braking power. The human hand holds the brake handle, pulls the brake mechanism through the cable or rod, and presses the brake block (or disc) on the rim (or brake disc) of the wheel to establish the braking torque. , so as to stop the rotation of the wheel, realize its braking function, and achieve the purpose of decelerating or parking the vehicle; During the whole process of the end of the dynamic action, the friction pair (brake block or disc or wheel rim or brake disc) is in a sudden press-fit contact.

Problems solved by technology

[0002] Vehicles, especially small vehicles, such as bicycles, mopeds and small motorcycles, usually use the power of the human hand as the braking power. The human hand holds the brake handle, pulls the brake mechanism through the cable or rod, and presses the brake block (or disc) on the rim (or brake disc) of the wheel to establish the braking torque. , so as to stop the rotation of the wheel, realize its braking function, and achieve the purpose of decelerating or parking the vehicle; During the whole process of the end of the dynamic action, the friction pair (brake block or disc or wheel rim or brake disc) is in a sudden press-fit contact. During the braking process, the friction pair may produce relative sliding movement, but the brake block is controlled The force of the disc (or disk) always exists. When the vehicle is moving rapidly, the friction pair suddenly bites, so that the wheels rotating at high speed are locked, the wheels stop, and the vehicle rushes forward or loses balance under the action of inertia, slips or falls sideways. Turning, this phenomenon may cause the occupants to frighten, and may cause personal injury or damage to the vehicle; in the above braking process, the friction pair is continuously pressed together to generate braking torque, the wheels stop and the vehicle coasts. , the result is that the entire braking process is prolonged, that is, the braking efficiency of the above-mentioned braking method is poor, and in an emergency, the driving safety hazard will be generated due to the low braking function; at the same time, the above-mentioned relative sliding will be intensified. The wear of the softer friction block or disc in the friction pair shortens its service life; in order to deal with the above problems such as locking, long braking stroke and short service life of the friction pair, a modern automobile adopts a method to overcome these defects. Braking method - point-release brake, the point-release brake system uses hydraulic or pneumatic power to automatically control the intermittent contact of the friction pair. The structure of this system is relatively complicated. Therefore, in small vehicles such as bicycles and motorcycles etc. cannot be popularized and applied, but point-release braking is undoubtedly the development direction of its braking technology for any kind of vehicle
