Embodiment

[0026] With reference to the accompanying drawings, in a tracked vehicle, there is a full disc brake on the left and right, located between the output shaft of the integrated transmission device in the engine room and the input shaft of the side reducer. Under the action of the control system and its actuators, it undertakes the work of normal braking, emergency braking and parking braking, and can provide a torque that stops the vehicle from the maximum speed and keeps the vehicle on a slope of 60%. The loading method of the full-disc brake is to press the dynamic and static discs under the action of the control oil through the brake cylinder, and achieve the purpose of deceleration or parking through friction.

[0027] The original installation state of the full-disc brake is the parking state of the brake, so the parking function should be released before the vehicle is started; Operate the brake pedal as required to inject the control fluid of the corresponding brake oil c...

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...
