Wet-type multi-disc brake for heavy truck

Abstract

A wet type multi-disc brake for a heavy truck comprises a body, a composite air chamber, a dynamic friction disc, a static friction disc, a brake piston and a rotating disc. An outer end cover is detachably arranged on the outer side of the body. An inner end cover is detachably arranged on the inner side of the body. A composite air chamber support frame is fixedly arranged on the inner end cover. The composite air chamber is arranged on the composite air chamber support frame. A parking brake air chamber and a service brake air chamber are arranged in the composite air chamber. A force transmission gear shaft is arranged on the composite air chamber support frame. A rotating disc is arranged on the inner side of the inner end cover. A gear ring is arranged on the rotating disc. A slope transmission assembly is arranged on the inner side of the rotating disc. A brake piston is arranged on the other side of the slope transmission assembly. A dynamic friction disc and a static frictiondisc are arranged on the other side of the brake piston. The requirements of laws and regulations for the heavy truck can be met, the braking torque can be adjusted through the set speed on a long slope, the heavy truck runs at a constant speed, and vehicle accidents caused by the brake can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of vehicle control systems, and in particular relates to a wet multi-disk brake for heavy trucks. Background technique [0002] The country has higher and higher requirements for the safety and reliability of medium and heavy transport vehicles, relevant laws and regulations have gradually been improved, and the requirements for the safety and reliability of the complete braking system are also increasing. The brake device is in the form of drum and dry friction plate, which only realizes the functions of driving brake and parking brake. my country's total land area is about 9.6 million square kilometers, of which mountains, hills, plateaus and other terrains account for about 2 / 3, and roads in mountainous areas in my country account for a large proportion. In recent years, my country's infrastructure construction has advanced by leaps and bounds, and the road conditions in mountainous areas have also impro...

AI Technical Summary

Problems solved by technology

[0005] The existing wet brake adopts hydraulic method for braking. It is used on construction machinery. Its braking performance cannot meet the requirements of the national regulations on heavy-duty transport vehicles, and it cannot meet the requirements for braking on long and long slopes.

[0006] Existing heavy-duty vehicle brakes use pneumatic drum brake units. Continuous or repeated braking is required when driving on expressways or western highways with height drops, on gentle slopes or on roads with complex road conditions, and the brakes generate a large amount of Heat, which can cause a tire blowout or a vehicle accident that catches fire in severe cases
