Abstract
The utility model discloses a wet-type multiple-disc brake which aims at solving the problem that an existing automobile brake device is not suitable for being used in mines or in pits where flammable and explosive gas is produced. According to the wet-type multiple-disc brake, a covering board (7) is connected with a cylinder body (6) fixed on an axle housing (10) through a plurality of bolts, a brake block base (5) is installed between the covering board (7) and the cylinder body (6), a plurality of disc-type brake blocks (8) are arranged on a hub (3) and on the brake block base (5), the disc-type brake blocks (8) on the hub (3) and the disc-type brake blocks (8) on the brake block base (5) are arranged in a staggered mode, a piston (9) is arranged in the cylinder body (6), and one end, facing outwards, of the piston (9) makes contact with the disc-type brake blocks (8). Therefore, the wet-type multiple-disc brake has the advantages of being capable of being used in the mines or in the pits where the flammable and explosive gas is produced.
Description
Technical field
The utility model relates to a kind of braking device, relates in particular to a kind of wet multi-disc brake.
Background technique
At present, a kind of like this braking device is disclosed on the market, its structural feature is: by expanding the formula brake shoe, expansion formula brake shoe pad, expansion formula brake block and support are formed, expansion formula brake block is connected with expansion formula brake shoe spacers by rivet, one end of expansion formula brake shoe is connected with support by pin, the other end of expansion formula brake shoe and similar cam to be being coupling of flat tactile, when starting braking device, hydraulic pressure or pneumatic mechanism turn an angle axle, at this moment, an end that is flat expands outwardly an end of expansion formula brake shoe, thereby reaches the braking purpose, because this structure is open braking device, when braking, easily produce spark, therefore, this structure is not suitable for the mine haulage vehicle in the mine or the narrow road traveling braking in down-hole, especially is not suitable in the mine that produces flammable explosive gas or the down-hole use.
Summary of the invention
The purpose of this utility model provides a kind of wet multi-disc brake that can use in mine or the down-hole of generation flammable explosive gas.
For achieving the above object, the utility model wet multi-disc brake, formed by disc brake pad, piston, brake bar, cover plate and cylinder body, cover plate is connected with the cylinder body that is fixed on the axle housing by a plurality of bolts, the brake bar also is installed between cover plate and cylinder body, a plurality of disc brake pads are arranged on the wheel hub, a plurality of disc brake pads are installed on the brake bar, disc brake pad on disc brake pad on the wheel hub and the brake bar is staggered the arrangement and arranges, piston is arranged in the cylinder body, and a piston end outwardly contacts with disc brake pad.
Described cylinder body is provided with is convenient to the hole that hydraulic oil enters, and this hole communicates with the cavity that is formed by cylinder body, piston and piston ring, is convenient to promote piston a plurality of disc brake pads have been pushed braking action.
Also be provided with on described cylinder body and be convenient to the hole that lubricant oil enters, this hole communicates with the cavity that is formed by disc brake pad, wheel hub, semiaxis, axle tube, bearing, axle housing, cylinder body and piston, plays lubricated and thermolysis.
Between described cover plate and wheel hub, be provided with the oil sealing that can prevent oil leak.
After adopting this structure, because cover plate is connected with cylinder body by a plurality of bolts, at cover plate and the cylinder body that has been fixed on the axle housing the brake bar is installed also, a plurality of disc brake pads are arranged on the wheel hub, a plurality of disc brake pads are installed on the brake bar, brake block on disc brake pad on the wheel hub and the brake bar is staggered the arrangement and arranges, piston is arranged in the cylinder body, a piston end outwardly contacts with brake block, a plurality of disc brake pads are sealed in by wheel hub, cover plate, in the cavity that brake bar and cylinder body constitute, thereby the spark that produces because of friction between a plurality of disc brake pads when preventing from braking spatters the potential safety hazard that causes outward, reaches the purpose that can use in mine or the down-hole of generation flammable explosive gas.
