Control device for emergency stop of truck

Abstract

The invention aims to solve a problem that a braking distance is not easy to shorten when a truck is braked emergently in the prior art. The invention discloses a control device for emergency stop ofa truck. The device comprises a wheel body and a cover plate. A connecting frame is fastened to a left side of an upper surface of the cover plate through screws. A mounting plate is welded at a top end of the connecting frame; a fastening screw is mounted on the mounting plate; and a rack is fastened to the right side of the upper surface of the cover plate through the screws, a first motor is fixedly installed at the top end of the rack, a rotary disc is installed in the middle of the first motor, a second rack is welded to the side surface of the rotary disc, a spiral spring is fixedly connected to the middle of the lower surface of the cover plate, and a sliding rod is arranged in the spiral spring. Through driving of the first motor, alternate friction is performed between wheel bodies through anti-skid layers, braking of a vehicle is accelerated, then through cooperation of air bags and air bag belts, control over the distance between the air bag belts can be achieved, dual braking can be performed on the vehicle conveniently, and the device is safer.

Description

technical field [0001] The invention relates to the field of truck control, in particular to a control device for truck emergency parking. Background technique [0002] A truck is a commercial vehicle designed and equipped primarily for carrying goods, whether it can tow a trailer or not. The large cargo truck is a special flat car used to transport bulky and heavy goods, such as large machine tools, generator and steam turbine rotors, steel rolling equipment, transformers, chemical synthesis towers and complete sets of equipment. [0003] The inertia of the truck is relatively large. When there is an emergency, the truck cannot stop quickly, which will cause serious traffic accidents. It is difficult to stop the truck only through the braking of the truck itself, which prolongs the stopping distance of the truck. This will affect the braking of the truck, and if the brake is directly applied to the tire of the truck, the friction on the tire will be increased, which will c...

Problems solved by technology

[0003] The inertia of the truck is relatively large. When there is an emergency, the truck cannot stop quickly, which will cause serious traffic accidents. It is difficult to stop the truck only through the braking of the truck itself, which prolongs the stopping distance of the truck. This will affect the braking of the truck, and if the brake is directly applied to the tire of the truck, the friction on the tire will be increased, which will cause the tire to blow out too quickly, and the safety factor is poor. Therefore, it is urgent to design A control device for emergency parking of trucks to solve the deficiencies in the prior art
