Circulating water internal cold friction drum for brake device

Abstract

The invention discloses a circulating water internal cold friction drum for a brake device, which is suitable for internal expansion and external bundling brake devices and can be used for braking a vehicle retarder, a brake, hoisting equipment and transporting equipment. The circulating water internal cold friction drum comprises an external hub 1, an internal hub 2, a cover plate 3, a guide plate 4, a spoke 5, connecting keys 7, a water inlet 8, a water outlet 9 and the like. The internal hub and the external hub are connected together by using a plurality of keys 7 and a fastening member to form an integral friction drum. The hubs are arranged on a rotating shaft through the spoke and rotate with the rotating shaft. Cooling water enters a friction drum water channel from the water inlet 8 under a certain pressure, flows in the hubs under the guidance of the guide plate 4, and finally enters a heat radiator from the water outlet 9, and the cooling water enters the next cooling circulating process after being cooled by the heat radiator. During the brake, friction heat generated by the hubs and an external bundling brake sheet or / and an internal expansion brake sheet is carried away by the cooling water, thus the temperature of the working surface of the friction drum is lowered.

Description

technical field [0001] The patent of the present invention relates to a circulating water internally cooled friction drum for a brake device, which is suitable for internal tension type and external beam type brake devices, and can be used for retarding and braking of vehicle retarders, brakes, lifting equipment and transportation equipment. moving device. Background technique [0002] The brake cooling system emerged in the 1980s. There are two traditional cooling methods: air cooling and water cooling. The cooling efficiency of the air cooling system is not high, and the temperature of the working surface of the friction drum is high, which is easy to burn the working surface of the friction drum and the brake pads, reducing the service life of the brake device. [0003] Currently widely used electric eddy current automobile retarder, because the heating of the stator itself is affected by the temperature rise of the rotor, and the problem of temperature rise during the o...
