Abstract
The utility model relates to a driving-axle brake of a large forklift truck, which relates to forklift-truck structures and comprises a brake disk, an end-part axle-housing seat and a brake, wherein the brake disk is fixed on the outer circle of a rear-end shell of a hub of a driving axle; and the driving-axle brake is characterized in that: the brake is a wet-type brake comprising a brake seat, an annular cover, a pair of brake calipers, an oil material filled in the annular cover and a hydraulic cylinder, the brake seat of the wet-type brake is fixedly installed on the end-part axle-housing seat of the driving axle, a central hole of the annular cover of the wet-type brake is hermetically sleeved on the outer circle of the rear-end shell of the hub of the driving axle in the mode of movable fit, and the two caliper mouths of the pair of brake caliper are sleeved with clearances at both sides of the brake disk. The driving-axle brake has the advantages that: after the wet-type brake is installed on the large forklift truck, an overheating phenomenon of brake can not occur, and the driving-axle brake is used for braking in place and is steady to operate.
Description
Technical field:
The utility model relates to fork lift truck structure, particularly the drive axle drg of large-scale fork truck.
Background technology:
The fork truck fork truck is made up of vehicle frame, drive axle (propons), steeraxle (back axle), engine installation, driving system, operating system, hydraulic efficiency pressure system, brake system, door frame and clump weight.Propons is a drive axle, and back axle is a steeraxle.The drg of drive axle is a dry brake.Dry brake is made up of hydraulic actuating cylinder and clipping brake clamp fixing on brake disc, brake mount, the brake mount, and brake disc is fixed on the cylindrical of end housing behind the drive axle wheel hub, and brake mount is fixed on the axle housing seat of drive axle axle housing end.Glancing impact, hydraulic actuating cylinder action promote the brake clamp jaw clamping brake disc enforcement braking in opposite directions of brake disc both sides.Braking force is very big for large-scale fork truck, brake clamp jaw and brake disc friction force are very big, and the dry friction cal val between brake clamp jaw and the brake disc is also very big, overheated easy generation brake failure, make the fork truck operation not in place, even the generation collision wait other cargo accident.
And this problem is considered in the design of large-duty loader, uses oil-immersed multi-disk brake.Oil-immersed multi-disk brake structure and the difference of dry brake structure mainly are to increase a radius cross sectional shape circular cowling and the rotary seal that are U-shaped, circular cowling is wrapped in inner chamber with brake clamp and brake disc sealed type, be full of oil plant in the inner chamber, oil plant plays cooling effect.But this structure is not applied on the fork truck.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of drive axle drg of large-scale fork truck is provided.
Scheme of the present utility model is: comprise fixing brake disc, the end bridge shell block of end housing cylindrical behind the wheel hub of drive axle, and drg, it is characterized in that: drg is the oil plant of filling in brake mount, circular cowling, brake clamp, the circular cowling, the oil-immersed multi-disk brake that hydraulic actuating cylinder is formed, the oil-immersed multi-disk brake brake mount is fixedly mounted on the drive axle end bridge shell block, oil-immersed multi-disk brake circular cowling medium pore running-fit sealed type is linked in behind the drive axle wheel hub on the end housing cylindrical, and brake clamp two jaw gaps are linked in the brake disc both sides.
Advantage of the present utility model is: after large-scale fork truck was installed oil-immersed multi-disk brake, brake did not produce superheat, and brake puts in place, operates steadily.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
The utility model structure comprises fixing brake disc, the end bridge shell block 1 of end housing cylindrical behind the wheel hub of drive axle, and drg, it is characterized in that: drg is the oil plant of filling in brake mount, circular cowling 2, brake clamp, the circular cowling 2, the oil-immersed multi-disk brake that hydraulic actuating cylinder is formed, the oil-immersed multi-disk brake brake mount is fixedly mounted on the drive axle end bridge shell block 1, oil-immersed multi-disk brake circular cowling 2 medium pore running-fit sealed types are linked in behind the drive axle wheel hub on the end housing cylindrical, and brake clamp two jaw gaps are linked in brake disc 3 both sides.
Claims (1)
1. the drive axle drg of large-scale fork truck, comprise fixing brake disc, the end bridge shell block (1) of end housing cylindrical behind the wheel hub of drive axle, and drg, it is characterized in that: drg is the oil plant of brake mount, circular cowling (2), brake clamp, the interior filling of circular cowling (2), the oil-immersed multi-disk brake that hydraulic actuating cylinder is formed, the oil-immersed multi-disk brake brake mount is fixedly mounted on the drive axle end bridge shell block (1), oil-immersed multi-disk brake circular cowling (2) medium pore running-fit sealed type is linked in behind the drive axle wheel hub on the end housing cylindrical, and brake clamp two jaw gaps are linked in brake disc (3) both sides.
