The suction tube of an electric vacuum pump (1) is connected with one end of a vacuum rubber tube A (2), the other end of the vacuum rubber tube A (2) is connected with the orifice of an energy storage tank (3), on which a check valve A (16) is mounted, the other orifice of the energy storage tank (3) is connected with one end of a vacuum rubber tube B (4), the other end of the vacuum rubber tube B (4) is connected with one orifice of a four-way tube (5), another orifice of the four-way tube (5), on which a check valve B (17) is mounted, is connected with one end of a vacuum rubber tube C (6), the other end of the vacuum rubber tube C (6) is connected with the orifice of an intake tube (7), another orifice of the four-way tube (5) is connected with one end of a vacuum rubber tube D (9), the other end of the vacuum rubber tube D (9) is connected with the orifice of a braking booster (10), the internal thread of the last orifice of the four-way tube (5) is engaged with the mounting external thread of a pressure sensor (11), a transmission wire (12) of the pressure sensor (11) is connected with the pressure-sensing wire port of a control relay (13), and a control wire (15) of the control relay (13) is connected with the input port of the electric vacuum pump (1). The vacuum-assisted brake assist is characterized in that: the structure is simple and compact, the effect of the vacuum-assisted brake assist is evident, and the vacuum-assisted brake assist can ensure that driving and vehicle rescue are safer, and is convenient and easy to use.
Description
Technical field
The utility model relates to the automobile brake technology, especially a kind of vacuum-assisted brake auxiliary device.
Background technology
Existing automobile adopts vacuum servo servo brake device, produces vacuum at engine inlets, gives the effect of brake servo unit power-assisted, but has following problem sometimes; 1, vehicle et out of order, driving engine can not the normal operation operations, need use the steel cable trailer, and engine inlets do not have vacuum, and braking effect is poor at this moment, can not guarantee the safety of suing and labouring.2, driver habit fuel-economizing and neutral gear slides, engine idling operation, degree of vacuum is lower, and braking effect descends, if this moment of braking continuously, its effect is poorer; When 3, neutral gear slided, chaufeur was failed in time to pinpoint the problems to take to arrange and is dragged and flame-out naturally if engine idle is unstable, and its traffic safety hidden danger is bigger.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, at the auxiliary vacuum that increases of brake servo unit, guarantees that car brakeing under any circumstance all is in normal condition.
Technical scheme that the purpose of this utility model adopts is, comprise electric vacuum pump, energy storage canister, four-way piece, the driving engine that has air inlet pipe, brake servo unit, pressure sensor, the control relay that has power lead, the aspirate tube of its electric vacuum pump is connected to vacuum hose A one end, another termination energy storage canister of vacuum hose A is equipped with the mouth of pipe of check valve A, another mouth of pipe of energy storage canister connects vacuum hose B one end, another termination four-way piece mouth of pipe of vacuum hose B, another mouth of pipe that four-way piece is equipped with check valve B connects vacuum hose C one end, the vacuum hose C other end taps into the tracheae mouth of pipe, four-way piece also has a mouth of pipe to connect vacuum hose D one end, the vacuum hose D other end is connected the mouth of pipe of brake servo unit, last mouth of pipe negative thread of four-way piece and pressure sensor are installed the outside thread engagement, the transmission line of pressure sensor is connected with the pressure sensing line interface of control relay, and the control line of control relay links to each other with the electric vacuum pump input interface.
Its working process of the utility model, when not having vacuum or degree of vacuum to be lower than safety value in the brake servo unit, the pressure driver passes to control relay with signal, and control relay instruction Motorized vacuum pump startup makes and forms vacuum in the brake servo unit; When degree of vacuum reached normal condition, electric vacuum pump quit work.
The utlity model has simple and compact for structurely, its effect is obvious, makes to drive and more have a sense of security when suing and labouring vehicle, characteristics such as simple and direct simultaneously easy to use.
