Abstract
The invention discloses a method for assisting in enlarging the brake contact area of a vehicle. A transmission mechanism installed on a fixed bracket of the vehicle is included. A supporting arm is installed at the output end of the transmission mechanism. A brake disc is installed at the tail end of the supporting arm. The supporting arm swings along with rotation of the output end of the transmission mechanism, and the brake disc is driven to rotate and makes contact with the ground, so that frictional force is generated, and the brake performance is improved; when braking is not needed, the transmission mechanism drives the supporting arm to rotate to lift the brake disc, at the moment, the contact area is reduced, and the maneuvering performance of the vehicle recovers to the original state. By the additional arrangement of an assisting brake system, when braking is needed, the contact area between the vehicle and the ground is enlarged to improve the braking performance; when braking is not needed, the brake disc is separated from the ground, and thus the maneuvering performance recovers. The brake area is enlarged selectively while the maneuvering performance of the vehicle is not damaged.
Description
Technical field
The present invention relates to the brake system of automobile, specifically refer to the method for a kind of donkey engine brake area of contact.
Background technology
Brake system effect is: make the automobile in traveling carry out forced deceleration according to the requirement of chaufeur and even stop; Make the automobile of stagnation of movement steadily halt under different kinds of roads condition; The car speed of descent run is made to keep stable.Master cylinder belongs to automobile brake system, function mainly provides brake power-assisted, brake power-assisted effect is just had after only having vehicle motor to start, the cart such as bus and lorry adopts air pump force aid system, roadlice adopts oil pump force aid system, main oil master cylinder of stopping is vacuum booster pump, when master cylinder power-assisted, chaufeur controls to touch on the brake when wheel cylinder oil pressure acts on brake pressure the dynamics of pedal can be easily a lot, if so automobile is not activated driving engine, even if so with doing the best, the pedal that touches on the brake also cannot be floored.What play brake action to automobile can only be act on automobile and the direction external force contrary with vehicle traveling direction, and the size of these external force is all random, uncontrollable, therefore automobile must be installed a series of special arrangement to realize above-mentioned functions.Brake system of car refers to the safety traffic in order to ensure automobile technically, improves the average velociity etc. of automobile, and on automobile, installs the special stop mechanism of brake equipment.In general brake system of car comprises service braking device and stop device two overlaps independently device.Wherein service braking device is handled by chaufeur pin, therefore also known as foot brake.Stop device is hand-operated by chaufeur, therefore also known as hand brake device.The function of service braking device makes car deceleration just under steam or stops in the shortest distance.And the function of stop device makes the automobile be parked on various road surface keep motionless.But sometimes in case of emergency, two kinds of brake equipments can use and increase the effect of automobile brake simultaneously.The automobile of some special purpose and the automobile travelled through mountain area of being everlasting, for a long time and continually braking will cause service braking device overheated, on these automobiles, therefore often set up the complemental brake system of various different types so that when descending stabilizing speed.
Various existing braking is all rely on the friction force between tire and road surface to realize braking above, when needs increasing friction force improves deceleration and stopping performance time, need the width increasing tire to increase area of contact, but the increase of tire area can cause the maneuvering performance of automobile to decline, therefore, the maneuvering performance of its braking potential and automobile is conflict body, often causes the reduction of maneuvering performance when increasing deceleration and stopping performance.
