Abstract
The invention discloses a vacuum replenishment system for a brake device of a motor vehicle in an unpowered state. The vacuum replenishment system consists of a vacuum pump, an air guiding pipe, a vacuum tank, an engine connected vacuum pipe, a brake device vacuum pipe, a connection air pipe, a power cord, a gulp valve and a vacuum monitoring switch. The vacuum replenishment system for the brake device of the motor vehicle in the unpowered state has the benefits as follows: when the motor vehicle is shut down accidentally and is in the unpowered state, the vacuum control for the brake device is restored in time, and failure of a brake function of the brake device is avoided; and accordingly, traffic accidents are reduced or prevented due to the fact that the brake device of the motor vehicle is in a safety state all the time. The vacuum replenishment system can be taken as a pneumatic supply and used for inflating a vehicle tyre.
Description
Technical field
The present invention relates to braking device for motor vehicle field, be specifically related to the unpowered state brake gear of self-propelled vehicle vacuum make-up system, the vacuum supply of brake gear system during for self-propelled vehicle accident extinguishing.
Background technology
Braking device for motor vehicle is comprised of three parts such as transmission shaft, fixation hollow axle, high resiliency sealing rubber rings.Wherein fixation hollow axle sleeve, on transmission shaft, leaves larger space between the two, in this space, high resiliency sealing rubber ring is installed.Rubber ring inner ring is fixed with transmission shaft rigid attachment all the time, and outer ring studs with some friction linings, leaves certain gap with fixation hollow axle inside diameter surface.While not being filled with high pressure air in high resiliency sealing rubber ring, there is gap in the inside diameter surface of the friction lining on it and fixation hollow axle, and at this moment, transmission shaft can freely rotate.While being filled with high pressure air in high resiliency sealing rubber ring, rubber ring expands because of inflation, it is large that its external diameter becomes, therefore gap originally and between fixation hollow axle disappears, friction lining becomes rigidity with fixation hollow axle and contacts, now, transmission shaft in fixation hollow axle and stop transmission, is realized the function of brake by rubber ring " swollen dead ".After high resiliency sealing rubber ring internal gas pressure discharges, its internal diameter diminishes, and transmission shaft is free to rotate again.Self-propelled vehicle accident extinguishing is common mechanical breakdown, the thing of the danger close of the self-propelled vehicle accident extinguishing in normally travelling, and flame-out rear braking lost efficacy, power steering lost efficacy, and chaufeur is difficult to grasp vehicle; Above-mentioned braking device for motor vehicle is traditional structure and mode.
In recent years, along with the progress of technology, there is basic change in such structure; As long as braking device for motor vehicle vacuum system is not destroyed, even self-propelled vehicle accident extinguishing, brake system can not lose efficacy.This just needs, on self-propelled vehicle, vacuum make-up system is installed, once self-propelled vehicle accident extinguishing starts vacuum make-up system immediately, to guarantee the supply of braking device for motor vehicle vacuum.Regrettably, existing self-propelled vehicle does not configure this vacuum make-up system.
Summary of the invention
The object of the present invention is to provide the unpowered state brake gear of a kind of self-propelled vehicle vacuum make-up system, the vacuum supply of brake gear system during for self-propelled vehicle accident extinguishing, to prevent the invalid traffic accident causing of the brake gear causing because of self-propelled vehicle accident extinguishing; Another function of the present invention is to serve as the effect of pneumatic supply, for the inflation of motor tire.
For achieving the above object, the present invention has adopted such technical scheme:
State brake gear vacuum make-up system that described self-propelled vehicle is unpowered, is comprised of vacuum pump, ventilation flue, vacuum reservoir, driving engine connection vacuum lamp, brake gear vacuum lamp, connection tracheae, power lead, gulp valve, vacuum monitoring switch; It is characterized in that, one end of vacuum pump is provided with freeing pipe, and the other end is provided with ventilation flue, and ventilation flue's the other end connects one end of vacuum reservoir; The structure sidepiece of vacuum reservoir is provided with driving engine and connects vacuum lamp and brake gear vacuum lamp and gulp valve; The vacuum reservoir other end is provided with connection tracheae; Connecting tracheae and vacuum monitoring switch connects; One end of vacuum monitoring switch is vacuum monitoring shell, and in vacuum monitoring shell, sealing is fixed with rubber bowl, between rubber bowl and vacuum monitoring shell, contact switch is installed, one end of contact switch connecting power line, and the other end of power lead is connected vacuum pump.
Adopt after such structure, during vacuum pump work, make in vacuum reservoir in vacuum state; When vacuum state is in setting threshold, rubber bowl disconnects the contact switch of installing in vacuum monitoring shell, stops the mode of operation of vacuum pump; When vacuum state is not enough, while being in outside setting threshold, rubber bowl makes the contact switch contact of installing in vacuum monitoring shell, makes vacuum pump in running order, makes all the time the vacuum state in setting threshold in vacuum reservoir.Now, the gulp valve of installing on vacuum reservoir is in closed condition.Driving engine connects vacuum lamp and brake gear vacuum lamp difference connecting engine and brake gear, once motor-car accident extinguishing, when unpowered state, recovers vacuum control to brake gear in time, avoids the brake function of brake gear invalid; Thereby guarantee in a safe conditionly all the time because of the brake gear of self-propelled vehicle, reduce or stop the generation of traffic accident.
The gulp valve of installing on vacuum reservoir is in opening, while making vacuum pump in running order all the time, this device can serve as the effect of pneumatic supply, and the freeing pipe that install vacuum pump one end mates with corresponding pneumatic element, can be for the inflation of motor tire.
Beneficial effect of the present invention is, when motor-car accident extinguishing, when unpowered state, in time brake gear is recovered to vacuum control, avoids the brake function of brake gear invalid; Thereby guarantee in a safe conditionly all the time because of the brake gear of self-propelled vehicle, reduce or stop the generation of traffic accident.This device can serve as the effect of pneumatic supply, for the inflation of motor tire.
