Abstract
The utility model discloses an urgent danger prevention braking device for an automobile, which is arranged on an automobile axle and comprises a difunctional spring hydraulic cylinder connected with a control oil circuit. A piston rod of the difunctional spring hydraulic cylinder is hinged with a knife plate at the upper part of a braking plate; connector links on two sides of the braking plate are hinged with a baseframe fixed on the car axle; and shovel teeth are arranged at the edge at the front end of the braking plate and matched with a ground position. The control oil circuit comprises a hand control valve, a one-way valve, a hydraulic pump and an oil tank, which are in closed-circuit connection sequentially; oil pipes are led out of both a front cylinder and a rear cylinder of the difunctional spring hydraulic cylinder and connected with the hand control valve; the difunctional spring hydraulic cylinder is divided into the front cylinder and the rear cylinder through a piston, and an energy storage spring is arranged in the rear cylinder; and the hand control valve is arranged in a driving cab. The urgent danger prevention braking device for the automobile has the advantages of simple structure, practical functions, large brake moment, high efficiency, safety and reliability, sturdiness and durability, simpleness in maintenance and low cost, and is suitable to be installed and used in automobiles of various models and sizes.
Description
Technical field
The utility model relates to a kind of automobile emergency hedging brake equipment.
Background technology
Throughout the year in the driving, unavoidably can run into the influence of sleet, freezing weather and cause the road surface slippery brake failure.Some other hard to guard against unforeseen circumstances (as faults such as air pump, pipeline, brake activation valve, compressed air brake cylinder, brake drum heatings) also can appear simultaneously.At present, existing automobile brake technology does not all have any effective way, particularly heavy-duty truck, motorcoach because of the brake failure problem to above-mentioned situation, and personal injury and vehicle, property accident frequently take place.
The utility model content
The utility model purpose is to provide a kind of automobile emergency hedging brake equipment, and rate of braking is big, effective.
To achieve these goals, the utility model adopts following technical scheme: automobile emergency hedging brake equipment, be arranged on the automobile axle, comprise and control oil channel bonded assembly double-acting spring hydraulic actuating cylinder, the knife plate on the piston rod of double-acting spring hydraulic actuating cylinder and slipper top is hinged, the junction button of slipper both sides is hinged with the support that is fixed on the automobile axle, and the slipper front end edge is along being provided with teeth, and teeth and ground location are equipped with.
Described control oil channel comprises closed circuit successively bonded assembly hand control valve (HCV), check valve, Hydraulic Pump, fuel tank, and the front and back cylinder of double-acting spring hydraulic actuating cylinder is all drawn oil pipe and is connected with hand control valve (HCV).
Described slipper, support and double-acting spring hydraulic actuating cylinder all are hingedly fixed on the automobile axle by steel pin.
Establish one or two spring hydraulic cylinder on the described slipper.
Described double-acting spring hydraulic actuating cylinder comprise by piston be separated into preceding cylinder and the back cylinder, in the back cylinder energy stroage spring is set.
Described hand control valve (HCV) is arranged in the operator's compartment.
Described spring hydraulic cylinder is made as double-acting spring hydraulic actuating cylinder or single-acting spring hydraulic cylinder.
The utility model is simple in structure, function is practical new, reasonable in design, works alone, and not restricted by any objective factor, and brake torque is big, usefulness is high, and is safe and reliable, sturdy and durable, easy to maintenance, with low cost, is applicable to that various models and big roadlice install and use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a birds-eye view of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1 and Figure 2, automobile emergency hedging brake equipment, be arranged on the automobile axle, comprise and control oil channel bonded assembly double-acting spring hydraulic actuating cylinder 2, the piston rod 7 of double-acting spring hydraulic actuating cylinder 2 is hinged with the knife plate 8 on slipper 1 top, slipper 1 front end edge is along being equipped with teeth 9, and teeth 9 is equipped with ground location.Control oil channel comprises closed circuit successively bonded assembly hand control valve (HCV) 6, check valve 5, Hydraulic Pump 4, fuel tank 3, and the front and back cylinder of double-acting spring hydraulic actuating cylinder 2 is all drawn oil pipe and is connected with hand control valve (HCV) 6.Slipper 1, double-acting spring hydraulic actuating cylinder 2, pedestal 12 all are hingedly fixed on the automobile axle 11 by steel pin.Double-acting spring hydraulic actuating cylinder 2 comprise by piston 6 be separated into preceding cylinder and the back cylinder, energy stroage spring 13 is set in the back cylinder.Check valve 5 is arranged on Hydraulic Pump 4 rear ends.Hand control valve (HCV) 6 is arranged in the operator's compartment.
Before the running car, (is example with the double acting hydraulic cylinder) moves hand control valve (HCV) 6 to walking position, hydraulic oil enters double-acting spring hydraulic actuating cylinder 2 front ends by oil pipe 14 and promotes piston rod and move backward and make the withdrawal of cylinder inner spring, the hydraulic oil of double-acting spring hydraulic actuating cylinder 2 rear ends is back to fuel tank 3 by oil pipe 15 through hand control valve (HCV) 6, simultaneously, piston rod 7 pulling slippers 1 leave the road surface, automobile traveling.
During emergency braking, move hand control valve (HCV) 6 to braking position, hydraulic oil is back to fuel tank 3 by oil pipe 14 through hand control valve (HCV) 6 fast under the effect of energy stroage spring 13 in double-acting spring hydraulic actuating cylinder 2, simultaneously, piston rod 7 quick travel under the effect of energy stroage spring 13 promotes the slipper 1 direct road surface of rubbing of shoveling and makes automobile brake.
Strengthen glancing impact if desired, move hand control valve (HCV) 6 to the heavy braking position, hydraulic oil enters the thrust that the hydraulic actuating cylinder rear end further increases piston rod by oil pipe 15, strengthens the lock torque of slipper 1.
If when using single-acting spring hydraulic cylinder, need to change hand control valve (HCV) 6, remove hydraulic pipe 14 and get final product.
