Description
Technical field
The utility model relates to a kind of automobile braking equipment, especially a kind of vehicle brake ancillary system.
Background technology
Because the whole society is to the pay attention to day by day of automotive safety, the braking problem of vehicle has become producer needs key problems-solving in design with in producing.The ABS system has become the standard outfit of most manned vehicles at present, this system is mainly by being installed on the variation of the wheel speed sensors supervision vehicle wheel rotational speed on the wheel, and coherent signal passed to the ABS control unit, when the ABS control unit obtains vehicle wheel rotational speed and the signal of fast-descending occurs, will make steerman just in the judgement of emergency braking, the ABS control unit can be pressed into the braking liquid in the master brake cylinder in the brake piping at once, braking force is passed on each car side brake that connects brake piping, carry out emergency braking.Consideration for simplified design and car gut line, the brake piping of vehicle adopts Y shape to arrange mostly, namely two brake pipings are controlled respectively two front-wheel brakes, article three, brake piping is controlled two rear wheeies brake, the shortcoming of this layout is to cause easily the braking force of two trailing wheels not enough under emergency, and the situation such as the direction of traffic that causes because of the difference of front and back wheel braking force is out of control.China national Department of Intellectual Property discloses the utility model patent (notification number: CN201309479Y) of a kind of " based on the automobile assistant braking system of ABS system " by name, content is: comprise the ABS system that is installed on the car body, described ABS system comprises the ABS control unit, wheel speed sensors, electromagnetic valve and the ABS solenoid regulated valve that described electromagnetic valve is regulated, wheel speed sensors connects the ABS control unit, also comprise the pedal displacement sensor that the displacement to brake pedal detects, vehicle auxiliary braking control unit and the active tonifying Qi electromagnetic valve of being controlled by vehicle auxiliary braking control unit, the pedal displacement sensor connects vehicle auxiliary braking control unit, initiatively be communicated with by gas circuit between tonifying Qi electromagnetic valve and the described electromagnetic valve, vehicle auxiliary braking control unit and ABS control unit join.This utility model can be improved braking retardation and the not enough problem of braking under the vehicle emergency situation, but can not solve the unbalanced problem of vehicle front and back wheel braking force.
The utility model content
The purpose of this utility model is to solve the unbalanced problem of front and back wheel braking force that rear-wheel braking force that existing motor vehicle braking system exists is not enough and cause thus, and a kind of vehicle brake ancillary system that can balance front and back wheel braking force is provided.
For achieving the above object, the utility model adopts following scheme: a kind of vehicle brake ancillary system, comprise control setup and the sensing device that is connected with control setup respectively and executive device, described control setup comprises the ABS control unit, described sensing device comprises wheel speed sensors, described executive device comprises master brake cylinder, and described master brake cylinder is connected with the ABS control unit, and described ABS control unit is connected with 4 car side brakes of vehicle respectively by brake piping.Change an original brake piping into connect respectively two trailing wheels two brake pipings, improved the braking force level of trailing wheel under the emergency, and so that the braking force of front and back wheel reaches balance.
As preferably, described wheel speed sensors has 4, is installed on respectively on 4 wheels of vehicle.Can realize like this rotating speed of each wheel accurately being monitored and respectively braking the braking effect and the safety that improve vehicle.
As preferably, described wheel speed sensors has 3, is installed on respectively on two front-wheels and back axle of vehicle.For general vehicle, especially trailing wheel is the vehicle that dependent hangs, and layout can reduce expenditure under the premise that security is guaranteed like this, reduces cost.
As preferably, described ABS control unit also is connected with car speed sensor, between described ABS control unit and the brake piping blowdown valve is installed.Car speed sensor can help the ABS control unit to judge the slippage situation of vehicle, when the descending speed of vehicle wheel rotational speed during faster than the descending speed of the speed of a motor vehicle, the ABS control unit just can be controlled the on-off action that blowdown valve carries out certain frequency, prevents the situation that causes wheel lockup because braking force is excessive and then make vehicle slip.
The beneficial effects of the utility model are: improve the braking force of trailing wheel under the equal conditions, prevented the potential safety hazard that causes because of front and back wheel braking force difference, and simple in structure, promote easily.
Description of drawings
Fig. 1 is the scheme drawing of the utility model embodiment 1;
Fig. 2 is the scheme drawing of the utility model embodiment 2.
Wherein:
The 1-ABS control unit, 2-wheel speed sensors, 3-master brake cylinder, 4-brake piping, 5-car side brake, 6-car speed sensor, 7-blowdown valve.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further:
Embodiment 1: as shown in Figure 1, a kind of vehicle brake ancillary system, comprise ABS control unit 1,4 wheel speed sensors 2 that ABS control unit 1 is connected with car speed sensor 6 and is installed on respectively 4 wheels, ABS control unit 1 also is connected with master brake cylinder 3 and blowdown valve 7, and blowdown valve 7 is connected with 4 car side brakes 5 of vehicle respectively by 4 brake pipings 4.
The wheel speed sensors 2 that embodiment 2:ABS control unit 1 connects is 3, is installed on respectively on two front-wheels and back axle of vehicle, and other is identical with embodiment 1.
When ABS control unit 1 obtains the wheel speed change information that wheel speed sensors 2 transmits, after judging steerman and attempting to implement emergency braking, braking liquid in the master brake cylinder 3 will be pressed into fast 4 brake pipings 4, control 4 car side brakes 5 and carry out emergency braking, 1 pair of speed of a motor vehicle change information and wheel speed change information that transmits from car speed sensor 6 of ABS control unit compares simultaneously, after the danger of judging vehicle generation sideslip, ABS control unit 1 can be opened blowdown valve 7, brake piping 4 is carried out the pressure release operation of certain frequency (being generally 60-120 time/second), prevent wheel lockup, reach the effect of stablizing braking direction and shortening stopping distance.
