Mining dump truck wet-type brake

Abstract

The invention relates to the technical field of brakes, in particular to a mining dump truck wet-type brake. The mining dump truck wet-type brake comprises an axle, wherein the axle is sleeved with adisc driving wheel; a friction plate is arranged outside the disc driving wheel; the friction plate is sleeved with a shell; two ends of the friction plate are each provided with a traveling brake piston and a parking brake piston correspondingly; a traveling oil injection port and a parking oil injection port are respectively formed in the traveling brake piston and the parking brake piston; an oil inlet seat is arranged outside the parking oil injection port; an oil return seat is arranged outside the traveling oil injection port; a leak-proof sleeve is arranged between the oil return seat and the traveling oil injection port; one end, connecting with the traveling oil injection port, of the leak-proof sleeve is sleeved with a leak-proof cover; an adjusting mechanism is arranged betweenthe leak-proof cover and the leak-proof sleeve; an installation groove is formed in one side of the oil return seat; a fixing frame is inserted into the installation groove; and a fixing mechanism isarranged at one end, connected with the outer side of the oil return seat, of the fixing frame. The mining dump truck wet-type brake is simple in structure, capable of improving the service life of the brake, and good in braking effect.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a wet brake for mining dump trucks. Background technique [0002] Automobile brakes are one of the important components of automobiles, and their braking performance is directly related to the safety performance of automobiles, especially for mining dump trucks in large-scale open-pit mining industries, where the operating environment is harsh and the road conditions are uneven. The device wears a lot and has a low service life. At the same time, the mining dump truck has a heavy load and is more dependent on the brakes. If the braking effect of the braking system is not good, it will greatly affect the transportation speed of the car body, and even cause Safety accidents, most of the existing mining dump trucks use wet brakes for braking, but the hydraulic oil of wet brakes tends to accumulate impurities during long-term use, which affects the normal operation of the brakes, and ...
