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 vital effect 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 for the operating control of control 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 reducing speed of motor vehicle or parking.Yet, because self-propelled vehicle is when running at high speed, self can produce powerful inertia, and tire and contact area of ground less, the friction drag of its generation is much smaller than the force of inertia of self-propelled vehicle, and the speed of a motor vehicle is higher, its inertia is larger, 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 occurs, 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 on the one hand the friction material that brake component such as brake shoe are used can directly affect braking procedure, generally select the material with stable friction coefficient and excellent abrasive resistance to make brake component, such as asbestos and powder alloy etc., although 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 simultaneously other 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 in the relatively short interior parking of distance, can not effectively avoid train operation accident; 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-skid 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.
Summary of the invention
