Circumferential locking brake device for truck wheel brake axle

Abstract

The invention relates to a circumferential embracing brake device of a wheel type brake axle for a motor truck. The circumferential embracing brake device comprises brake shoes and embracing mechanisms matched with the brake shoes, wherein brake friction linings are arranged on inner peripheral faces of the brake shoes. The circumferential embracing brake device has the beneficial effects that 1) the brake device fit for the wheel type brake axle for the motor truck with a circumferential clamping braking structure is provided; 2) the circumferential embracing brake device provided by the invention is characterized in that a clamping braking effect is achieved by a brake wheel and the brake shoes with reduced circumferential inner diameters, a traditional brake drum is not adopted so that the danger of drum cracking caused by a braking external support force is greatly reduced, and meanwhile, the brake device is arranged on the outer periphery of the brake wheel so that the heat radiating condition is greatly improved, the stability and reliability of the brake device are increased, and the hidden danger of road traffic accidents is further reduced; 3) the circumferential embracing brake device of the wheel type brake axle for the motor truck has the advantages of simple structure, convenience in maintenance, reasonable design, reliable use property, safe and reliable running and long service life.

Description

technical field [0001] The invention belongs to the technical field of automobile axles, and in particular relates to a circumferential locking brake device for a wheel brake axle of a truck. Background technique [0002] Although the existing automobile drum brake has been improved many times and its braking performance has been perfected, there are still some problems in the heat dissipation after friction braking when braking or emergency braking under heavy load or down a long slope , Accidents that easily cause brake failure due to the high temperature generated by the brake often occur, which has become a major safety hazard in vehicle driving. In order to solve the above-mentioned problems, the current heat dissipation and cooling method of automobile drum brakes is to install a water storage tank and a water spray device on the vehicle, and to achieve the purpose of forced cooling by spraying water to the drum brakes. However, adding a water tank increases the extra...

AI Technical Summary

Problems solved by technology

However, adding a water tank increases the extra load of the car on the one hand, reduces the limited carrying capacity of the vehicle, and at the same time brings inconvenience and trouble to road safety and vehicle maintenance, and there are also safety hazards caused by the failure of the sprinkler device or improper operation. Hidden danger

When encountering cold weather, the pipeline of the sprinkler device will often be unable to work normally due to freezing, or the local ice on the road surface will cause traffic accidents due to the cooling of the spraying water

Under high temperature conditions, the sudden cooling by spraying water will easily cause the brake drum to break, and even cause the brake to fail, which will bring serious consequences to the driving of the vehicle and life and property.
