Truck braking device realizing rapid cooling

Abstract

The invention discloses a truck braking device realizing rapid cooling. The truck braking device comprises a large shaft base and a strong plate, the strong plate is perpendicularly and fixedly connected to the large shaft base, a hinging shaft rack is arranged on the edge of the strong plate, two symmetrical hinging shafts are arranged on the hinging shaft rack, two symmetrical half braking shoesare hinged to the two hinging shafts, braking pieces are arranged on the outer surfaces of the two half braking shoes, symmetrical flat-strip-shaped cams are arranged between the free ends of the twohalf braking shoes, after the cams rotate, the two braking pieces are opened to abut against to the inner side of a round-rotation braking drum, the braking drum is fixedly connected to a wheel boss,the wheel boss is rotatably connected to a supporting shaft in the large shaft base through a bearing, the cams movably penetrate through the strong plate through rotating shafts to be connected to adriving mechanism, and a water cooling system is installed on the braking drum. According to the truck braking device, the cams rotate to make the two half braking shoes abut against the braking pieces, braking of a truck is realized stably and reliable, the water cooling system is arranged, in this way, the effect of cooling is good, and braking is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of automobile brakes, and relates to a fast-cooling brake device for large trucks. Background technique [0002] With the development of the transportation industry, large trucks have become an indispensable means of transportation in this industry. [0003] Due to the insurmountable serious problems in the actual operation of the road conditions, the load of the vehicle and the existing design of the vehicle, it is often necessary to use the brakes frequently during long-distance transportation. The system generates a lot of heat due to friction during the whole process, and the high-risk environment The various working parts in the car are easy to oxidize, resulting in thermal recession, which makes the friction coefficient between the brake shoe and the brake shoe smaller, reduces the braking performance, and more seriously leads to brake failure and rollover accidents. Though adopt the method for sprayi...

Problems solved by technology

On the one hand, the traffic control department of the traffic police strictly prohibits the release of brake water at high speeds, and points will be deducted for fines; on the other hand, large trucks cannot go downhill without adding water.

The government once ordered to solve this problem, but it has not been completely solved until now
