Abstract

The invention relates to a brake of a high-speed heavy-load vehicle, which has the structure capable of providing a torque enabling the vehicle to stop at maximum speed, enabling the vehicle to be continuously on a slope of 60 percent, meeting the requirements on a high-power heavy-load high-speed vehicle and conveniently enhancing the maneuvering performance of the vehicle. The brake of the high-speed heavy-load vehicle comprises a connecting disc assembly with a C / SiC friction lining, a braking disk assembly with a C / SiC friction lining, a press plate assembly with a C / SiC friction lining, a movable wheel ball bearing, a rotational wheel ball bearing assembly, a spring, the C / SiC friction linings, an insulating plate, a roller, a supporting roller, a connecting disk, a flat key, a spring and an involute positioning block, wherein the spring is used for enabling the movable wheel ball bearing assembly to be reset; the roller provides the axial movement of the movable wheel ball bearing; and the spring is used for enabling a rotational wheel ball bearing to be reset. The invention can ensure that the service life of the brake is greatly prolonged and the braking torque and the reliability of the brake are greatly enhanced, has excellent performance and good reliability and is suitable for batch production.

Description

Technical field:

[0001] The invention relates to a high-speed heavy-duty vehicle brake, which belongs to the field of vehicle brakes. Background technique:

[0002] At present, the brakes that are often used on high-speed and heavy-duty vehicles are band brakes. The structural forms of the brakes used in the transmission system are band brakes and planetary steering gears, which jointly complete the steering, deceleration, parking and parking functions of the vehicle. . This kind of brake has large radial load, uneven wear, laborious operation and low braking deceleration during braking.

[0003] The other is the caliper disc brake that uses copper-based powder metallurgy as the friction component material from the late 1980s to the early 1990s. Vehicles can no longer meet the requirements of high-speed, high-power, and heavy-duty vehicles. Invention content:

[0004] The purpose of the present invention is to provide a high-power full-disc brake for high-speed heavy-du...
