Abstract
The utility model discloses an automobile auxiliary brake device, which comprises an air reservoir and an air exhaust pipe, wherein an air exhaust brake valve is installed on the air exhaust pipe, connected to a manual control switch via a guide line and communicated with the air reservoir via an actuating pipeline; an electromagnetic valve is arranged on the actuating pipeline and respectively connected to an accelerator pedal switch installed on an accelerator pedal and a clutch pedal switch installed on a clutch pedal via guide lines; and the accelerator pedal switch and the clutch pedal switch control on-off of the electromagnetic valve, when the accelerator pedal or the clutch pedal is stepped on, the electromagnetic valve is switched off, and when the accelerator pedal or the clutch pedal is released, the electromagnetic valve is switched on. The automobile auxiliary brake device has the advantages of having reliable braking, convenient operation, safety and reliability and low failure rate and being especially suitable for auxiliary brake systems of large and medium-size vehicles.
Description
Technical field
The utility model relates to a kind of automobile brake member, specifically, is a kind of by being the auxiliary brake device for automobile that the exhaust of automobile is not freely braked.
Background technology
At present light-duty truck has generally only disposed the service brake emergency brake system of unifying, when the lower long slope of running car on mine or mountain highway, owing to continue braking, to change into heat energy again by that part of kinetic energy that potential energy changes into, and brake wheel or brake disc temperature are risen rapidly, make brake wheel or brake disc produce certain heat fade phenomenon, cause braking force wretched insufficiency or brake system to lose efficacy when serious, produce serious consequence.
In order to overcome the problems referred to above, Chinese patent CN200981540 discloses a kind of " the slow formula auxiliary brake mechanism of single cylinder automobile exhaust gas ", it comprises and control handle bonded assembly exhaust throttle system and synchronous shutdown systems, by the kinetic energy of automobile slide being converted into the heat energy that produces behind the engine compresses air, then launched machine cooling system consumes, and car speed is reduced or maintenance.Yet, because the brake system of automobile needs driving engine that power is provided, behind engine off, cause the degradation failure of braking, influence traffic safety; In addition, cause some automobile not turn to behind the engine off.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of safe auxiliary brake device for automobile.
In order to address the above problem, auxiliary brake device for automobile of the present utility model, comprise air receiver and freeing pipe, exhaust brake valve is installed on freeing pipe, this exhaust brake valve links to each other with manual switch through lead, described exhaust brake valve is connected with described air receiver through control line, on described control line, be provided with electromagnetic valve, this electromagnetic valve through lead respectively be installed in Das Gaspedal on accelerator pedal switch link to each other with clutch pedal switch on being installed in pedal of clutch, the switch of this accelerator pedal switch and clutch pedal switch control electromagnetic valve, when Das Gaspedal or pedal of clutch are stepped on, described closed electromagnetic valve, when Das Gaspedal or pedal of clutch unclamp, the opening of described electromagnetic valve.
When the needs auxiliary braking, open manual switch, exhaust pipe of engine major part is closed in exhaust brake valve work, and the pressure in the freeing pipe rises to 0.3～0.4MPa, engine piston must overcome this pressure in exhaust stroke, thereby increase the B.P. of driving engine greatly, engine piston is subjected to the counter pressure of gas, is tied to wheel through bent axle by transmission, increase the rolling resistance of wheel, thereby reduced the speed of a motor vehicle; When needs gearshifts or stop, when pedal of clutch was stepped on, clutch pedal switch was closed electromagnetic valve, made exhaust brake valve quit work, and freeing pipe is opened, and had avoided when pedal of clutch is stepped on driving system and disconnected engine off like this.Equally, when the needs acceleration, when stepping on the throttle pedal, accelerator pedal switch is closed electromagnetic valve, makes exhaust brake valve quit work, and freeing pipe is opened.
In technique scheme, described manual switch is installed on the steering column.
In technique scheme, described air receiver is communicated with the air extractor duct of air compressor.
Compared with prior art, the beneficial effects of the utility model are: braking is reliable, at the bottom of easy to operate, safe and reliable, the fault rate, is particularly suitable for adopting in the auxiliary braking system of big-and-middle-sized vehicle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Further the utility model is illustrated below in conjunction with drawings and Examples.
Referring to Fig. 1, auxiliary brake device for automobile mainly is made of air compressor 1, air receiver 2, control line 3, manual switch 4, accelerator pedal switch 5, clutch pedal switch 6, electromagnetic valve 7, exhaust brake valve 8, freeing pipe 9, noise silencer 10, freeing pipe 9 links to each other with noise silencer 10, exhaust brake valve 8 is installed on freeing pipe 9, this exhaust brake valve 8 links to each other with the manual switch 4 that is installed in steering column 13 through lead, simultaneously, this exhaust brake valve 8 is connected with air receiver 2 through control line 3, and this air receiver 2 is communicated with the air extractor duct of air compressor 1.On control line 3, be provided with electromagnetic valve 7, this electromagnetic valve 7 through lead respectively be installed in Das Gaspedal 12 on accelerator pedal switch 5 link to each other with clutch pedal switch 6 on being installed in pedal of clutch 11, the switch of this accelerator pedal switch 5 and clutch pedal switch 6 control electromagnetic valve 7, when Das Gaspedal 12 or pedal of clutch 11 are stepped on, described electromagnetic valve 7 is closed, when Das Gaspedal 12 or pedal of clutch 11 unclamp, the opening of described electromagnetic valve 7.
Principle of work of the present utility model is: when manual switch 4 is opened, and exhaust brake valve 8 work, when Das Gaspedal 12 or pedal of clutch 11 were stepped on, electromagnetic valve 7 was closed, and exhaust brake valve 8 is not worked.
