Abstract
The utility model relates to an automobile emergency braking device which is composed of a gas tank, a change-over valve, a cylinder and frictional braking blocks, wherein the air collector is connected with a scavenging valve through a pipe, the scavenging valve is connected with the cylinder through a pipe, a piston in the cylinder divides the cylinder into an upper and a lower air chambers, and the piston rod of the piston is connected with the frictional braking blocks. If an emergency occurs, the frictional braking blocks are made to contact the ground hard and fast within two seconds to create favorable braking action. Unless the change-over valve is pulled, the frictional braking blocks can contact the ground forever, which can make automobile difficult to move. Therefore, the utility model can nicely function as theft protection.
Description
The utility model relates to a kind of automobile-use brake auxiliary device, the emergency braking auxiliary device that particularly a kind of automobile is used.
No matter existing automobile is hand evil spirit or foot brake, contacts the generation friction with ground by four tires entirely after all and brakes.Car speed is higher, for the safety of driver and crew's lives and properties, strengthens safety factor, takes to widen tire, solves the loss that the minimizing collision is caused to increase with the way that contacts and install onboard safety air bag of floor area.But the not good enough declaration of an accident that causes of defective brake and effect, the report that air bag is choked to death child, and famous wear or the like, the safety that air bag all is described is extremely limited, crucial one is that self-propelled vehicle is stopped.
The purpose of this utility model is to provide a kind of increase self-propelled vehicle to contact with ground to the public, strengthens self-propelled vehicle brake effect, produces braking and anti-theft effect simultaneously, can avoid or reduce the vapour-pressure type automobile emergency braking device of life property injures and deaths and loss.
This device is by storage tank, and change-over valve, cylinder and friction braking piece are formed, and gas tank is connected with scavenge valve by pipeline, and scavenge valve is connected with cylinder by pipeline, and what cylinder was interior is divided into upper and lower air chamber with plug with cylinder, and the piston rod of piston is connected with the drag friction piece.
Admission port, safety valve, compression indicator, inlet and outlet piping mouth are arranged on the storage tank; Pressure-modulation valve and exhausr port are arranged on the pipeline between storage tank and the hand change over valve; Hand change over valve respectively with gas tank pipeline and cylinder into and out of plumbing connection, with the cylinder bonded assembly into and out of tracheae under the effect of hand change over valve, inlet, outlet are relatively to change.Into and out of tracheae when being connected with two or more cylinders, the inlet, outlet pipeline connects upper chamber or the lower chamber that air chamber or lower chamber, a branching of pipes pipeline can only connect cylinder simultaneously respectively simultaneously, can not the upper chamber that connects this cylinder that the branching of pipes pipeline has, what have connects other cylinder lower chamber.
The cylinder fixed position is on the inboard chassis of four tires, and is parallel with tire when it is highly worked, and highly is higher than the ground of tire contact below, and its height is when tyre in operation is travelled, and the friction braking piece is difficult for being advisable by the finger stone contact.When piston was pushed lower chamber to, friction braking piece kiss the earth can utilize half pressure close proximity to ground of vehicle body at least.
Below in conjunction with description of drawings, principle of work and embodiment the utility model being advanced to do a step introduces.
Fig. 1 is the utility model brake device and plumbing connection scheme drawing thereof.
Fig. 2 is the utility model brake device embodiment scheme drawing.
Wherein: 1, storage tank; 2, safety valve; 3, compression indicator; 4, pressure-modulation valve; 5, hand change over valve; 6, cylinder (6-1 cylinder 1,6-2 cylinder 2,6-3 cylinder 3,6-4 cylinder 4); 7, piston; 8, friction braking piece; 9, pipeline connection; 10, pipeline; 11, exhausr port; 12, lower chamber; 13, upper chamber; 14, motor tire; 15, car chassis.
Principle of work of the present utility model is:
When automobile needs emergency braking, when foot brake can not reach requirement, operate hand change over valve to " B " position, will enter change-over valve " O " mouth from the high pressure gas of storage tank again through " C " mouth, enter the cylinder upper chamber by pipeline, the promotion descent of piston.The gas of lower chamber, is discharged by freeing pipe by " B " mouthful warp " A " mouth through pipeline again.At this moment, four simultaneously rapid kiss the earths of friction braking piece are realized emergency braking.After braking finishes, hand change over valve is lever operated to " C " position, the lower chamber that gas warp " O " mouthful pipeline to " B " mouth enters cylinder promotes piston stroking upward, and the gas of upper chamber is discharged through exhaust riser to " A " mouth by " C " mouth through pipeline, and friction braking piece built on stilts is resetted.Behind the friction braking block reset, hand change over valve is lever operated, and the air inlet/outlet of four cylinders all is closed to " A " position, and upper chamber is in vacuum state, and lower chamber is in the voltage stabilizing state, and four pistons and friction braking piece can not be free movable.
Advantage of the present utility model is:
1, as long as in the driving process of self-propelled vehicle, the storage tank of the full high pressure gas of storage can be depressed into change-over valve by pipeline automatically, one runs into emergency situation, when touching on the brake, pull hand change over valve, can make friction braking piece kiss the earth firmly in a second with the interior time, produce good braking action.
2, because the friction braking piece at urgent kiss the earth, has increased with ground-surface contact surface self-propelled vehicle and reaches more than one times, that is to say that the utility model has increased more than one times than the braking effect of existing self-propelled vehicle at least.
3, no matter technical solutions of the utility model are to use in the car load originating firm is produced, still make behind the product existing self-propelled vehicle improved and install, and all be very convenient.Just will produce corresponding product according to various vehicles installs.
4, because four friction braking pieces kiss the earth firmly, if do not pull change-over valve, it will contact to earth forever, make self-propelled vehicle be difficult to move.So the utility model has played theft-proof effect well.
Embodiment
Key of the present utility model is the intensity of the leakage of high pressure gas and cylinder, piston, piston rod because firmly when kiss the earth and road conditions difference to the cylinder assembly impaction lesion, all be that strength is bigger.So the design of cylinder assembly, processing and assembling, all essential its surplus that strengthens need be done or the like with the casting steel as cylinder block.
