Abstract
The utility model provides an outloading type clutch valve which comprises a valve body, a valve rod and an offsetting spring; at least one oil inlet and one oil outlet are arranged on the valve body; the oil inlet and the oil outlet are communicated with an inner chamber of the valve body; the valve rod is arranged in the inner chamber of the valve body; one end of the valve rod extends out of the valve body; and the offsetting spring is arranged between the other end of the valve rod and the valve body. In specific application, the clutch valve is arranged between a walking valve and a hydraulic motor of a wheel-type mechanical walking hydraulic system. When a clutch plate is pedaled by feet, the valve rod moves; and high-pressure oil enters the oil outlet from the oil inlet so as to realize outloading, thereby controlling the flow rate and the pressure of the hydraulic motor in order that the wheel-type machine achieves the aims of full clutching and half clutching. In the clutch valve, the wheel-type mechanical walking hydraulic system becomes a hydraulic pump-walking valve-clutch valve-hydraulic motor structure; and the clutch valve achieves the function of a clutch and can realize full clutching and half clutching in order that the starting of the wheel-type machine is smooth, the manipulating performance is improved, and the failure rate is reduced.
Description
Technical field
The utility model relates to the unloading valve that plays clutch action on the wheel machine of fluid motor-driven such as engineering machinery, agricultural machinery walking.
Background technique
At present, the vibration hydraulic system of the wheel machine of fluid motor-driven walking is made up of oil hydraulic pump, walking valve and oil hydraulic motor, directly connect between walking valve and the oil hydraulic motor, there is not engaging and disengaging gear, can not realize full clutch and half-clutch, have that starting is impacted greatly, problem such as flame-out easily, the rate of fault height of motor when loading greatly.
Summary of the invention
The utility model provides a kind of discharging type clutch valve that the wheel machine starting is steady, manoeuvring performance improves, rate of fault reduces that makes at the deficiency of the vibration hydraulic system existence of existing wheel machine.
The utility model adopts following technical solution:
Discharging type clutch valve comprises valve body, valve rod and Returnning spring, valve body is provided with at least one filler opening and oil outlet, and filler opening and oil outlet all communicate with body cavity, and valve rod is installed in the inner chamber of valve body, one end stretches out valve body, between the other end and the valve body Returnning spring is installed.
The support that is used for fixing installation is installed on the valve body.
During concrete the application, the utility model is installed between the walking valve and oil hydraulic motor of wheel machine vibration hydraulic system.When pressing clutch plate, valve rod is moved with foot-operated, high pressure oil enters oil outlet from filler opening, realizes off-load, thereby the flow and the pressure of control oil hydraulic motor make wheel machine reach full clutch and half-clutch purpose.
The utility model makes the vibration hydraulic system of wheel machine become the structure of oil hydraulic pump-walking valve-clutch valve-oil hydraulic motor, the clutch valve plays the effect of clutch, can realize full clutch and half-clutch, makes the wheel machine starting steadily, manoeuvring performance improves, and rate of fault reduces.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, valve body, 2, valve rod, 3, support, 4, Returnning spring, 5, end cap, 6, second oil outlet, 7, first oil outlet, 8, filler opening.
Embodiment
As shown in drawings, discharging type clutch valve of the present utility model comprises valve body 1, valve rod 2 and Returnning spring 4, and valve body 1 is provided with inner chamber and three hydraulic fluid ports, is respectively that first oil outlet 7, second oil outlet 6 and 8, three hydraulic fluid ports of filler opening all communicate with the inner chamber of valve body 1.Valve rod 2 is installed in the inner chamber of valve body 1, and an end stretches out valve body 1.One end of valve body 1 is equipped with end cap 5, between end cap 5 and the valve rod 2 Returnning spring 4 is installed, and the other end of valve body 1 is equipped with the support 3 that is used for fixing installation.Between valve body 1 and the valve rod 2 seal ring is installed.
During concrete the application, discharging type clutch valve of the present utility model is installed between the walking valve and oil hydraulic motor of wheel machine vibration hydraulic system, makes the wheel machine vibration hydraulic system--walking valve----walking valve--clutch valve--structure of oil hydraulic motor that the structure of oil hydraulic motor becomes oil hydraulic pump by oil hydraulic pump.When pressing clutch plate, handle discharging type clutch valve of the present utility model with foot-operated, valve rod 2 is moved to left, high pressure oil enters first oil outlet 7 from filler opening 8, realize off-load, thereby the flow and the pressure of control oil hydraulic motor make wheel machine reach full clutch and half-clutch purpose.Valve rod 2 resets under the effect of Returnning spring 4.
Also second oil outlet 6 can be removed, change into first oil outlet 7 and communicating.
