Abstract
The utility model relates to an oil line of a steering clutch of a bulldozer. A central rotating shaft is arranged in a rear axle tank, a steering hydraulic oil tank is formed between two spacer plates of the rear axle tank, and a lubricating oil tank is arranged outside the two spacer plates. Two oil lines led to a clutch are axially arranged in the central rotating shaft and are provided with two oil inlets arranged in the steering hydraulic oil tank. The utility model separates the lubricating oil tank from the hydraulic oil tank and moves the oil inlets and a rotary seal into a middle tank body, so hydraulic oil can not be mixed with lubricating oil when a rotating sealing ring normally leaks oil so that the service life of a steering hydraulic system can be prolonged.
Description
The utility model relates to a kind of oil feeding line of bulldozer steering cluth.
The hydraulic pressure oil feeding line of existing bulldozer steering cluth, its oil-in place is positioned at the outer left and right sides clutch lubrication fuel tank of rear axle box two dividing plates, and hydraulic oil is mixed with lubrication oil, so have to through hole be set on dividing plate, share a fuel tank and uses hydraulic oil.So just cause the severe contamination of hydraulic oil, reduce Hydraulic Elements application life.
The purpose of this utility model is that a kind of bulldozer steering cluth oil circuit that hydraulic oil and lubrication oil are effectively isolated will be provided.
Introduce the technical solution of the utility model below in conjunction with drawings and Examples.
Fig. 1 is the utility model sectional view.
With reference to accompanying drawing, the central rotational axis 5 of steering cluth tie-plate 11 is equipped with at two ends, places in the rear axle box 12, is supporting clutch tie-plate 11 flange shaft bearing 6 outward by two dividing plates 7.Forming steering hydraulic fuel tank 9, two dividing plates between two dividing plates 7 is outward left clutch grease-box 10 and right clutch grease-box 8.In central rotational axis 5, two the left oil circuits 1 and the right oil circuit 4 that lead to clutch axially are set.Two oil-ins 2 are arranged, open on the valve seat 13 of central rotational axis 5, place in the steering hydraulic fuel tank 9, be communicated with steering hydraulic fuel tank 9 and oil circuit 1,4, between the central rotational axis 5 and valve seat 13 of oil-in both sides, be provided with rotating seal ring 3.
The utility model separates grease-box with hydraulic oil container, oil-in and rotatory sealing are changed in the middle housing, when the normal leakage of oil of rotating seal ring 3, hydraulic oil can not occur and mix with lubrication oil, can improve the application life of steering hydraulic system greatly.
