The utility model is characterized in that the utility model also comprises a hydraulic emergency replacement wheel and a hydraulic system of the hydraulic emergency replacement wheel, wherein the hydraulic emergency replacement wheel is fixed on the automobile frame crossbeam through the fixing bracket, a wheel and a piston rod are mutually connected to the hydraulic emergency replacement wheel and can freely rotate, expand and retract in a cylinder, the hydraulic system of the hydraulic emergency replacement wheel is installed on the automobile frame crossbeam and is connected with the hydraulic emergency replacement wheel to form a control loop. At the very moment of the tire burst of the front wheel, the hydraulic emergency replacement wheel can rapidly extend out and replace the tire-burst front wheel in the utility model, and accordingly, a front axle is instantaneously recovered to the state of parallelism with a road surface; a driver can continue to operate an automobile to turn so that the automobile can stop towards a roadside for repair, PLC causes a brake lamp to be bright simultaneously when the tire-burst front wheel is replaced, and back vehicles are warned of rear collision. Accordingly, the solicitation of serious accidents can be reduced or avoided because of the tire burst.
Description
Technical field
The utility model relates to the hydraulic pressure first aid that a kind of automobile front-wheel tyre-burst moment stretches out automatically and replaces wheel, and it can reduce or turn to out of control bumping and accident such as rollover because of front-wheel tyre-burst causes when avoiding vehicle operating.
Background technology
Known, according to China traffic department statistics, 40% traffic accident is caused that by tire fault wherein the accident of the quick-fried initiation of tire accounts for the total accident of tire more than 70%.Particularly front-wheel tyre-burst can make accident that direction out of control causes far surpass the back axle wheel accident of blowing out, and the propons wheel is blown out slowly becomes " stealthy killer " in the road traffic accident
" 1 "Automobile is in case blow out (particularly bogie), the driver is with the muscle power dish that is difficult to preserve the orientation, it is to take place to head on vehicle to bump against more accident with the left side that right lateral track the near front wheel is blown out, and road surrounded by mountains is the major cause that zanjon is gone in rollover by the limes marginis front-wheel tyre-burst.
At present, the first-aid method of blowing out has " dynamic monitoring tire pressure device " and " automobile flat tire automatic slow down device ", the former is controlled at accident potential before the generation, in case the latter blows out with best rate of deceleration automatic deceleration, still can handle but its condition precedent is an accident generation back bearing circle.In fact seriously blow out (referring to the tire pressure pop-off) its bearing circle many places in runaway condition, in utmost point meeting initiation collision or rollover in the short time, and in the majority with the passenger vehicle and the bogie that exceed the speed limit, overload.
" 1 " China grid motor report-2004.12.10 day
Summary of the invention
Cause propons to tilt to make motor turning out of control for solving automobile front axle revolver or right wheel moment of blowing out, bump against or tumble thereby cause with head-on sending a car, the utility model provides the hydraulic pressure first aid that moment stretches out automatically of a kind of automobile front-wheel tyre-burst to replace wheel, this hydraulic pressure first aid is replaced wheel and can be stretched automatically and replace the wheel of blowing out in the near front wheel (or off front wheel) moment of blowing out, propons is in time returned to and the road surface parastate, allow chaufeur can continue that Control of Automobile turns to so that stop place under repair to the limit, road, and it is simultaneously bright from command of execution stoplight stop lamp, prevention is knocked into the back, thereby reaches minimizing or avoid accident further to enlarge.The hydraulic pressure first aid is replaced wheel and can be repeatedly used.
The technical scheme in the invention for solving the technical problem is: between propons left and right sides tire and vehicle frame, each installs the hydraulic pressure first aid that front-wheel tyre-burst moment stretches out automatically and replaces wheel, when the left side (or the right) front-wheel tyre-burst moment, because of tilting to make the hydraulic pressure first aid rapidly, propons replaces wheel collision ground, when ground reaction force makes the oil cylinder upper cavity pressure be increased to setting value, the first aid of PLC (Programmable Logic Controller) automatic command hydraulic pressure is replaced to take turns to shoot out and is replaced the wheel of blowing out, thereby the propons instantaneous recovery is arrived and the road surface parastate, and knock into the back with the bright prevention of seasonal stoplight stop lamp, finished this process required time＜1 second approximately.In operator's compartment, be provided with left and right urgent hand push button, replace the wheel autonomous cruise speed system when malfunctioning, then can use urgent hand push button to make the hydraulic pressure first aid replace wheel and shoot out when the front-wheel hydraulic pressure first aid of blowing out.Urgent another purposes of hand push button is when vehicle maintenance, and whether wheel work is replaced in the first aid of periodic inspection hydraulic pressure normal and make the changing of tire jack and use.Wheel is replaced in the hydraulic pressure first aid become plurality of specifications, be installed on the various types of automobiles to adapt to by the support loads size design.This device can be repeatedly used.
The beneficial effects of the utility model are, when high-speed running automobile such as a propons left side (or right) wheel blow out moment, hydraulic pressure first aid replacement wheel can be stretched automatically and replace the wheel of blowing out, allow chaufeur can continue to handle motor turning so that stop place under repair to the limit, road rapidly, reduce or avoid causing the more purpose of major accident because of blowing out thereby reach.Automatically it is bright to stretch out the while stoplight stop lamp at hydraulic pressure first aid replacement wheel, and prevention back vehicle rear-end collision accident takes place.
