Abstract

A track vehicle emergency brake arrangement relating to vehicle machine manufacturing industry, which is mainly composed of an arc-shaped oil cylinder, a piston, a piston rod, a emergency brake folding track and a fixed connecting frame, characterized in that: when the vehicle brakes emergent on the muddy road surface, running with high speed, the vehicle body is towed downwards by quickly inputing emergency brake folding track connecting on the vehicle crossbeam to lower of vehicle tyre, the onward force of the vehicle is translated to the downward force, while increasing friction area, pressure is increased to increase friction force, thereby settleing problem of preventing running take-off and tyre burst when the vehicle brakes out of time on the ice-sliding road surface and running with high speed, and improving security of the vehicle.

Description

The crawl vehicle emergency braking apparatus
Technical field the utility model relates to a kind of crawl vehicle emergency braking apparatus, and it mainly is made up of arc oil gas cylinder, piston, piston rod, the folding crawler belt of emergency braking and the frame of captiveing joint, and it relates to the automobile mechanical manufacturing.Especially by importing the crawler belt that is connected on the car chassis crossbeam down to motor tire, car body is drawn downwards, make automobile power forward change downward pressure into, power forward is big more, it is just big more to change downward power, pressure boost when increasing the friction area, friction is increased, not only played anti-skidding effect, and avoid the directly friction automobile sideslip of blowing out that is heated of tire and road surface again, icing the ways face and running at high speed in emergency circumstances thereby reach automobile, fast the purpose of safety shut-down in time.
Background technology is present, the braking of known various automobiles, great majority all be to adopt to stop that wheel of the bus rotates that rear tyre produces friction with ground and stop motion, also has minority employing deceleration parachute and traction braking, not only be subjected to the restriction of geographical conditions, and brake untimely.Particularly speed is fast more, and the road surface is smooth more, and it is difficult more to brake.Especially just difficult more at muddy and slippery ground-surface emergency brakings such as ice and snow, rainwater, and the very difficult control of direction, therefore can not reach timely braking and guarantee purpose of safety.The automobile emergency of running at high speed braking, tire and road surface be the friction as easy as rolling off a log automobile sideslip of blowing out that is heated directly, causes to meet accident once more or lead to major traffic accidents, thereby works the mischief and lose to people's lives and properties.
The summary of the invention the purpose of this utility model provides a kind of crawl vehicle emergency braking apparatus.Make automobile when running at high speed, on muddy and slippery road surfaces such as ice and snow, rainwater, little from heavy and light, pressure, can not produce under the difficult situation of big friction braking, insert under the tire being connected in the folding emergency braking crawler belt of car chassis crossbeam, make automobile power forward be transformed into downward power, pressure boost when increasing the friction area, friction is increased rapidly, it has not only solved the problem of the anti-skidding automobile sideslips of muddy and slippery road surface emergency braking such as ice and snow, rainwater, reaches the automobile purpose of emergency braking fast and safely of running at high speed.And increased the skidproof function of automobile emergency brake safe again, improved the promptness and the safety of automobile emergency braking.
The purpose of this utility model is to realize like this, emergency braking apparatus is fixedly mounted on the crossbeam on chassis, automotive wheels front upper place, piston-rod lower end is connected with the strap of the folding crawler belt lowermost end of emergency braking, the top strap is connected with the captive joint frame, the captive joint frame is welded on the crossbeam of car chassis, non-emergent glancing impact, the folding crawler belt of emergency braking is folded in the front upper place of wheel, arc oil cylinder advances the oil extraction air valve up and down and is connected with high-pressure pipe with brake pump, open the capable oil of arc cylinder upper end during emergency braking and start the air inlet and exhaust valve gas pressure in piston, promoting piston rod launches the folding crawler belt of emergency braking, rapidly the emergency braking crawler belt is pushed under the wheel, by crawler belt car body is drawn downwards, change automobile power forward into downward power, when increasing the friction area, increased the downward pressure of automobile again, both play anti-skidding effect, and avoided tire and road surface direct friction to be heated again and blown out, thereby reached the emergency braking assurance purpose of safety of braking fast.
Owing to adopt such scheme, not only solved automobile under high-speed travel state, the untimely problem of brake under muddy and slippery road surface situations such as ice and snow, rainwater.Simultaneously, also having solved galloping emergency brake aftercarriage change of direction, emergency braking tire and ground direct friction is heated and blows out and produce dangerous for the second time problem.Thereby reached the fast and safely purpose of brake of automobile under muddy and slippery emergencies on the roads such as ice and snow, rainwater of running at high speed, avoided or reduced the generation of the heavy losses of property and personal injury traffic accident to greatest extent.
Description of drawings further specifies the utility model crawl vehicle emergency braking apparatus below in conjunction with accompanying drawing
Fig. 1, be the urgent front and back wheel emergency braking condition of crawl vehicle emergency braking apparatus scheme drawing.
Fig. 2, be the non-emergent braking of crawl vehicle emergency braking apparatus, the folding figure of the folding crawler belt of the closed emergency braking of oily cylinder.
Fig. 3, be crawl vehicle emergency braking apparatus emergency braking, oily cylinder is opened the folding crawler belt expansion drawing of emergency braking.
Fig. 4, be the non-emergent glancing impact of crawl vehicle emergency braking apparatus, the captive joint frame is welded in automotive frame, the folding figure of the folding crawler belt of emergency braking.
Fig. 5, when being crawl vehicle emergency braking apparatus emergency braking, the captive joint frame is welded in automotive frame, emergency braking folds the crawler belt expansion drawing.
Among the figure: 1, oil extraction air valve 7 is advanced in strap 2, piston rod 3, the folding crawler belt 4 of emergency braking, oil gas cylinder piston 5, arc oil gas cylinder 6, startup to the folding crawler belt of emergency braking bottom, closure is advanced oil extraction air valve 8, the folding crawler belt captive joint frame 9 of emergency braking, motor tire 10, car chassis crossbeam.
Crawl vehicle emergency braking apparatus arc oil gas cylinder (6) startup is advanced oil extraction air valve (7) closure and is advanced oil extraction air valve closure in Fig. 2, arc oil gas cylinder (5) is fixedly welded on the inboard of the preceding car chassis crossbeam of wheel (9) (10), the arc oil gas cylinder is inboard to be connected with captive joint frame (8), captive joint frame (8) upper end directly is welded on the crossbeam (10) of wheel (9) dead ahead car chassis, captive joint frame (8) lower end is connected with the folding crawler belt (3) of axle and emergency braking strap topmost, and emergency braking folds crawler belt (3) strap (1) bottom and is connected with piston rod (2) with axle.
