Abstract
The invention relates to a loader brake pump. The loader brake pump comprises a brake pump, and is characterized in that a cylinder body is arranged on one side of the brake pump; a push piston is inserted in the cylinder body; a screw rod is arranged in the center of the push piston; a hydraulic piston is screwed on the screw rod; a hydraulic oil cylinder sleeves the hydraulic piston; a through hole is formed in the upper end of the front part of the hydraulic oil cylinder; a thread is formed in the through hole; an oil tank is screwed on the thread; and a one-way on-off valve is additionally arranged in the through hole. According to the loader brake pump provided by the invention, as fed oil in the hydraulic oil cylinder is arranged at the front part of the hydraulic oil cylinder, the hydraulic piston cannot pass through an oil inlet in movement, a sealing ring cannot be worn, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of improvement of mechanical loader braking pump, especially relate to a kind of mechanical loader braking pump.
Background technology
Loader uses the brake equipment of gas cap oil form, be use in system have air-operated hydraulic brake pump, this brake pump side is provided with a cylinder opposite side and is provided with a hydraulic ram, entering cylinder interior by high pressure gas makes cylinder piston promote the piston of hydraulic ram, and then generation high pressure oil, make brake clamp work, block brake disc to brake, the oil inlet of the hydraulic ram of this brake pump is arranged on the side arm of oil cylinder, seal ring when hydraulic piston movement on piston can with oil inlet friction, use for a long time and will make ring wear, hydraulic oil is made to flow back in petrol storage tank from seal ring, do not produce high pressure oil, make braking failure, the present invention well solves existingly exists technical matters.
Summary of the invention
The invention provides a kind of mechanical loader braking pump, its oil inlet mainly solving the hydraulic ram of existing brake pump is arranged on the side arm of oil cylinder, seal ring when hydraulic piston movement on piston can with oil inlet friction, use for a long time and will make ring wear, hydraulic oil is made to flow back in petrol storage tank from seal ring, do not produce high pressure oil, make the technical matters of braking failure.
A kind of mechanical loader braking pump of the present invention, comprise a brake pump, be primarily characterized in that described brake pump side is provided with a cylinder block, described cylinder block inside is fitted with one and promotes piston, described promotion piston centre is provided with screw rod, described screw rod is screwed a hydraulic piston, described hydraulic piston outer cover is equipped with a hydraulic ram, described hydraulic ram nock is provided with a through hole, its through hole is provided with screw thread, described screw thread is screwed a petrol storage tank, in described through hole, has also been provided with a unidirectional on-off valve.
As preferably: described hydraulic piston is set with seal ring, and described hydraulic ram front portion is also provided with an oil outlet.
As preferably: described unidirectional on-off valve can only flow in hydraulic ram from petrol storage tank.
The invention provides a kind of mechanical loader braking pump, brake solution is poured into petrol storage tank inside, brake solution flows to hydraulic ram inside from petrol storage tank inside by check valve, when stepping on brake pedal, high pressure gas enter in cylinder block, high pressure gas promote piston-advance, be screwedly mounted on the hydraulic piston promoting piston front portion and promote hydraulic oil, hydraulic oil pressurized is made to become high pressure liquid force feed for brake clamp, oil-feed due to hydraulic ram inside is arranged on the front portion of hydraulic ram, hydraulic piston can not through oil inlet when moving, seal ring can not be worn and torn, extend the feature in service life.
