Abstract
The utility model discloses a disk brake for a forklift, which comprises a long half shaft. An axle housing is sleeved on the long half shaft, the front portion of the axle housing is rotatably provided with a wheel hub, and a disk seat of the long half shaft is fixedly arranged on a right end face of the wheel hub. A brake plate sleeved on the axle housing is fixed on an annular end face of the left end of the wheel hub. A tubular spline housing seat is fixedly sleeved in the middle of the axle housing, a disk friction plate seat is sleeved on the spline housing seat, and the friction plate seat is connected with the spline housing seat through matched splines. A friction plate corresponding to the brake plate is fixed on an annular front end face of the friction plate seat. A disk oil cylinder seat is fixedly sleeved at the rear portion of the axle housing, the oil cylinder seat is provided with an oil cylinder, and a piston rod of the oil cylinder is fixed at a rear end face of the friction plate seat. The brake plate is abraded in the whole end face, and contact area is more than 300% of that of a shoe brake. Therefore, brake torque is greatly improved, safety is remarkably improved, and service life is remarkably prolonged. The brake plate nearly doesn't need replacing all the life, clearance doesn't need regulating, and only strokes of the oil cylinder needs regulating.
Description
Technical field:
The utility model relates generally to fork truck drg technical field, relates in particular to a kind of fork truck plate disc brake.
Background technology:
The present shoe brake that the drg in the fork truck brake system all adopts below 7 tons more than 3 tons, the brake plate of shoe brake are ungulate shape structure, contact to be a contact; Contact surface is little, and braking moment is little, so brake plate is highly susceptible to wearing and tearing; Brake clearance is little; After brake plate uses a period of time, very unfavorable adjustment, the life-span is also short.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of fork truck plate disc brake to be provided, and it is big that it has a contact surface, the advantage that lock torque is big.
The utility model is realized through following technical scheme:
A kind of fork truck plate disc brake is characterized in that: include major semiaxis, major semiaxis is set with axle housing outward, and the axle housing front portion is rotatablely equipped with wheel hub, and the dish type seat of said major semiaxis is fixedly mounted on the right side of wheel hub; Be fixed with on the annular end face of said wheel hub left end and be placed in the outer brake plate of axle housing; The middle part fixed cover of said axle housing is equipped with the spline housing seat of tubular, is set with dish-shaped friction bar on the spline housing seat, and the friction bar is connected through the spline that cooperatively interacts with the spline housing seat; Be fixed with and the cooresponding friction lining of brake plate on the front end face of the annular of friction bar; The rear portion fixed cover of said axle housing is equipped with the dish-shaped oil cylinder seat, and oil cylinder is installed on the oil cylinder seat, and the piston rod of oil cylinder is fixed on the aft end face of friction bar.
Described a kind of fork truck plate disc brake, it is characterized in that: fixed cover is equipped with the dust boot of tubular on the annular outer wall of said oil cylinder seat, and dust boot is trapped among the position between oil cylinder seat and the wheel hub.
Described a kind of fork truck plate disc brake is characterized in that: be distributed with some oil cylinders on the front end face of the annular of said oil cylinder seat, the piston rod front end of oil cylinder is fixed on the corresponding position on the friction lining seat ring shape aft end face.
The working process of the utility model is:
When major semiaxis moves to the right,,, brake plate and friction lining are broken away from so move to right through the effect drive brake plate of wheel hub because the dish type seat of major semiaxis is fixedly mounted on the right side of wheel hub.
When major semiaxis moved to the left, the effect through wheel hub drove brake plate and moves to left again, made the opposite face of brake plate and the friction lining realization brake action of fitting each other.
The utility model changes plate disc brake into by original shoe brake.We keep drg and chassis connection dimension and outside dimension constant, the convenient installation, and commonality is very high, simultaneously, has designed hydraulic efficiency pressure system to plate disc brake, has increased by a cover cylinder apparatus.Mechanical brake system by original shoe brake changes hydraulic brake system into.More laborsaving when braking like this, slim and graceful.
The utility model has the advantages that:
Brake plate in the utility model is the circular discoid structure, and brake plate is whole end-face friction, and contact surface is more than 300% of shoe brake, so braking moment improves greatly, safety and service life increase substantially especially, and brake plate almost need not to change throughout one's life.And the gap need not adjust, and only needs the stroke of adjustment oil cylinder to get final product.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Referring to accompanying drawing.
A kind of fork truck plate disc brake includes major semiaxis 3, is set with axle housing 8 outside the major semiaxis 3, and axle housing 8 front portions are rotatablely equipped with wheel hub 9, and the dish type seat of said major semiaxis 3 is fixedly mounted on the right side of wheel hub 9; Be fixed with the brake plate 6 that is placed in outside the axle housing 8 on the annular end face of said wheel hub 9 left ends.
The middle part fixed cover of said axle housing 8 is equipped with the spline housing seat 7 of tubular, is set with dish-shaped friction bar 4 on the spline housing seat 7, and friction bar 4 is connected through the spline that cooperatively interacts with spline housing seat 7.Be fixed with and brake plate 6 cooresponding friction linings 5 on the front end face of the annular of friction bar 4.
The rear portion fixed cover of said axle housing 8 is equipped with dish-shaped oil cylinder seat 1, is distributed with some oil cylinders 2 on the front end face of the annular of oil cylinder seat 1, and the piston rod front end of oil cylinder 2 is fixed on the corresponding position on the friction bar 4 annular aft end faces.
Fixed cover is equipped with the dust boot 10 of tubular on the annular outer wall of oil cylinder seat 1, and dust boot 10 is trapped among the position between oil cylinder seat 1 and the wheel hub 9.
