Description
Technical field
The present invention relates to the brake system in mechanical field, specifically a kind of automobile standby emergency braking system.
Background technology
In passenger and freight work, the brake system performance of automobile is directly connected to people's life and property safety, the malfunctioning traffic accident directly causing of automobile brake system is countless, especially in the long descending section in hill path, because tired driver is driven or misoperation (as do not removed in time the cooling brake facing of cooling tank), brake facing is heated, and to cause brake failure be modal problem in charing.Especially suitable for long-distance tour special-use vehicle more needs to avoid the generation of problems at all.
General passenger vehicle only has a set of brake system, and wherein parking brake and service brake are a set of brake system in fact.Spare braking system generally just has on bold and unconstrained car.Also some has mentioned emergency braking system for subsequent use for existing patent and product, is all generally disposable: as the brake system of boot-foot type, being in an emergency need to brake time, stretch out below the boots foot brake device of fluid control on chassis.Utilize the weight of car body to be pressed onto the very large friction force of generation on boots pin, drawback is one, and hydraulic stroke is long, and reaction is slow; Its two, the boots pin area that lands is too little, when high speed, brake is very unstable suddenly; Its three, because ground contact area is little, speed is fast, impulsive force is large, and road has also been caused to certain injury;
Air bag brake system, being in an emergency need to brake time, ejects an air bag below on chassis, inflation rapidly, forms a large air cushion at vehicle bottom.Its drawback is one, on general coach, there is no source of the gas, needs distribution source again; Its two, air bag does not have directivity, can not control direction, ejects suddenly air bag unavoidably make passenger vehicle out of control and crash into steep cliff yet in the hill path of long descending; Its three, if air bag does is very thickly not easy folding carrying, if very thin being easy to of doing galled in the time of brake;
Cable type brake system, being in an emergency need to brake time, the nailing tools following on chassis directly injected steel nail on road, and the steel nail many hawsers of ining succession, help passenger vehicle slow down and brake.Its drawback is one, and road has been caused to unnecessary injury, needs to repair road afterwards; Its two, hawser brake can not be controlled the travel direction of passenger vehicle, easily continue to cause the accident, its three, this system is also generally disposable, needs to reinstall this system afterwards, and vehicle chassis is keeped in repair with crossing.
Above-mentioned three class emergency braking systems generally all can not repeated usage, and safety is not high yet, all needs to do a large amount of work or maintenance vehicle afterwards, or maintenance road.
Summary of the invention
For solve poor stability that emergency braking system of the prior art exists, easily cause highway or vehicle damage and can not repeated usage etc. problem, the invention provides a kind of automobile standby emergency braking system.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: a kind of automobile standby emergency braking system, mainly formed by oil cylinder and brake casing, the bottom of described brake casing is provided with the brake roller of buffer roll and many groups, and buffer roll is arranged on the front position of brake bottom half, in brake casing, be provided with Pressure Block, the bottom of Pressure Block is provided with friction lining, and there is gap between friction lining and brake roller, the top of Pressure Block is hinged with the piston rod of oil cylinder that is arranged on car beam bottom, the piston rod of oil cylinder tilts towards the front of vehicle, and the angle that piston rod and car beam form is 5-65 °,
Described Pressure Block top is provided with pushing block, and the upper end of pushing block and the piston rod of oil cylinder are hinged;
Described car beam bottom is provided with slideway, is arranged with slide block in slideway, and oil cylinder is arranged on slide block; The bilateral symmetry of described slideway is provided with jagged clamping band, and sawtooth be shaped as right-angled triangle, right angle is towards the rear of vehicle; On slide block, be also provided with jacking block, one end of jacking block is the inclined ramp consistent with sawtooth inclined-plane gradient, and this inclined ramp is fitted on the sawtooth inclined-plane of clamping band, and the other end of jacking block is connected with slide block by spring, and spring is in extended state; The upper articulation of described brake casing front end is provided with front tension bar, and hinged by the other end and the car beam of front tension bar, and brake casing is connected with the winch on car beam by chain;
On described jacking block, be also provided with the push rod for extension spring.
In the present invention, in the time of brake, the piston rod of oil cylinder stretches out, push Pressure Block and the friction lining at the seat end to ground, wipe contact by brake roller and ground plays braking action, and in this process, oil cylinder is fixed on slide block, jacking block on slide block is stuck in jagged clamping band, prevented oil cylinder after move; Spring is extended state, by stuck one end of jacking block in clamping band and prevent its disengaging;
In the present invention, the brake length of casing and the quantity of brake roller can design as required, in like manner, the stuck position in clamping band of the angle of inclination of cylinder piston rod and jacking block also can be adjusted as required, the angle that piston rod and car beam form is in 5-65 ° time, while not only having ensured brake, brake roller, buffer roll contact with the buffering on ground, make brake steadily, simultaneously, also antagonistic force piston rod being subject to is distributed to Che Liangshang, prevent the stressed excessive time fracture of piston rod, extended service life.
Beneficial effect: the present invention compares EMER emergency brake system of the prior art and has the following advantages:
1, owing to adopting brake roller brake, belong on rolling body and brake, the wearing and tearing that road pavement and vehicle cause are little;
2, because brake roller quantity is more, make total ground contact area larger than the wheel ground contact area of vehicle, braking effect is good, meanwhile, brake casing has certain length, makes the rectangular box that is distributed as of brake roller, while making to brake, there is good guidance quality, thereby it is safer to make to brake;
3, this device is packed up by winch at ordinary times, in the time of brake, remove after the braking of winch, this device falls rapidly under Action of Gravity Field, simultaneously, oil cylinder and slide block travel forward along slideway, buffer roll and brake roller kiss the earth successively, the piston rod of oil cylinder extends, and by Pressure Block and friction lining, complete vehicle weight is carried on brake roller, braking effect is obvious, and brake steadily.
