Embodiment Construction

[0011] Such as figure 1 Shown: The main components of the wet multi-disc brake are: half shaft housing 1, housing connecting screw 2, adjusting gasket 3, pad 4, stator 5, friction plate 6, spring guide screw 7, compression spring 8, Pressure plate 9, seal ring 10, brake housing 11, parking brake piston seal ring 12, disc spring 13, disc spring seat 14, parking brake piston 15, service brake piston 16, service brake piston seal ring 17. Manually release the brake screw 18, the central housing 19, and the half shaft 20. The half shaft housing 1, the brake housing 11, the sealing ring 10 and the central housing 19 are connected as a whole by sixteen housing connecting screws 2 to form the inner cavity of the brake. The pressure plate 9 is located between the brake housing 11 and the friction plate 6, three sets of compression springs 8 are evenly spaced in the circumferential direction of the pressure plate 9, and the compression springs 8 are pushed against the inner end surfac...

Abstract

The invention provides a multifunctional wet multi-disc brake, which comprises an axle shaft shell, a pallet, a stator plate, a friction plate, a compression spring, a pressure plate, a brake shell, a disc spring, a disc spring seat, a parking brake piston, a driving brake piston, a central shell, an axle shaft and the like, wherein the axle shaft shell, the brake shell and the central shell are connected as a whole through screws to form a brake cavity; the pressure plate is positioned between the brake shell and the friction plate; the compression spring is arranged on the pressure plate; the driving brake piston is arranged between the pressure plate and the brake shell; a parking brake piston is arranged between the brake shell and the disc spring seat; the disc spring is arranged between the disc spring seat and the parking brake piston; the stator plate and the friction plate are alternately arranged in turn between the pressure plate and the pallet; and the pallet and an adjustment washer are arranged in turn between the friction plate and the axle shaft shell. The brake has the advantages of simplifying the transmission system structure of a whole machine and having gentle brake, good safety, convenient operation and easy maintenance.

Description

(1) Technical field: [0001] The invention belongs to the field of engineering machinery and relates to a multifunctional wet multi-disk brake. (two) background technology: [0002] At present, most of the brake mechanisms of construction machinery products in my country use caliper disc brakes. Although caliper disc brakes have stable braking performance, can withstand the influence of temperature, water immersion and vehicle speed, and have good anti-fading performance, they only have Single disk, small friction area, high pressure per unit area, high working temperature, and poor heat dissipation conditions. With the continuous development of construction machinery that requires very strict braking performance, multi-disc wet brakes have been more and more widely used in recent years. Wet multi-disc brakes can be divided into common wet multi-disc brakes, wet multi-disc loss-of-pressure brakes, and multi-functional wet multi-disc brakes according to installation and workin...
