Description
Technical field
The present invention relates to a kind of brake equipment that is installed on the self-propelled vehicle.
Background technology
Self-propelled vehicle in the process of moving, its parking and deceleration are controlled by brake equipment, so brake equipment plays crucial effects to traffic safety.The conventional motor vehicle brake equipment generally include by brake bracket limit be installed in motor-driven axletree or wheel or on brake shoe and be used to control the operating control of brake shoe action.The brake equipment of this kind structure is to drive brake shoe by operating control, is lock torque so that brake shoe can apply resisting moment to high speed shaft or wheel, and this lock torque can make between tire and the ground and produce friction drag, forces self-propelled vehicle to slow down or stops.Yet, because self-propelled vehicle is when running at high speed, self can produce powerful inertia, and tire is relative with contact area of ground less, and the friction drag of its generation is much smaller than inertia force of motor vehicles power, and the speed of a motor vehicle is high more, its inertia is big more, so the brake equipment of said structure is for the self-propelled vehicle of running at high speed, can not in short range, stop, and stopping distance length very easily causes traffic accident; Another problem is that emergency braking is easy to tire locking (wheel stops to roll) after the phenomenon of tire locking takes place, owing to self-propelled vehicle can not turn to, thereby can be caused traffic accident.
In the prior art, solve material and these two aspects of structure that the braking problem is confined to change brake equipment usually, the operating temperature and the programming rate that generally believe the friction material that brake component such as brake shoe are used on the one hand can directly influence braking procedure, generally select material brake component for use with stable friction coefficient and excellent abrasive resistance, as asbestos and powder alloy etc., though select these materials can improve deceleration and stopping performance, but it can not increase the friction drag between tire and the ground, do not add other simultaneously yet and can improve the friction drag parts, simultaneously, when emergency braking, can not thoroughly solve the problem of tire locking, so the brake equipment of this kind structure can not make the self-propelled vehicle of running at high speed stop in short relatively distance, can not avoid train operation accident effectively; Be to adopt the ABS system on the other hand, it is the brake system of protected tyre locking, this system can make self-propelled vehicle can controlling party in braking procedure to, and on wet and slippery road surface, can also reduce stopping distance, but this system can not increase the friction drag between tire and the ground equally, same not additional other can improve the friction drag parts, so this system can not avoid train operation accident effectively.
