By adopting preceding solution, the beneficial effects of the utility model are: compared with existing fork truck, this clutch coupling device, be arranged at forklift gear-box outside upper, and be communicated with the arrangement of clutch of oil circuit and fork truck, thus the oil body entering arrangement of clutch is cushioned, the vibration of moment can not be formed.Be specially adapted to, on heavy fork truck, reduce the vibration because engine power greatly and easily causes, reduce to cause because of Long-term Vibration part life low, decrease the problems such as the easy damage that causes because of precise structure.Further, by arranging pressure spring, the second piston can being made when moving to left to obtain a resistance, the boost in pressure of oil body during its compression oil body can be slowed down, and the elastic force of pressure spring can be adjusted, to control the pressure of oil body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Now with detailed description of the invention, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1, the present embodiment provides a kind of clutch coupling device, it is outside upper that it is located at forklift gear-box, and be communicated with the arrangement of clutch of oil circuit and fork truck, comprise body 1, a cavity 2 is provided with in described body 1, described body 1 right upper portion is communicated with cavity 2 ground and is provided with oil inlet 3, the right side wall of described body 1 is communicated with cavity 2 ground and is provided with power-transfer clutch oil inlet 4, the lower right side of described body 1 is communicated with cavity 2 ground and is provided with return opening 5, described return opening 5 is located at the left side that oil inlet 4 projects, described body 1 top is communicated with oil inlet 4 ground and is provided with a time delay oil pocket 6, described time delay oil pocket 6 is connected with the left part of cavity 2, the two ends, left and right of described cavity 2 are respectively equipped with first piston 7, second piston 8, spring 9 is connected with between described first piston 7 and the second piston 8, be provided with a step 21 in described cavity 2 to move right to limit first piston 7.The pipe diameter of described time delay oil pocket 6 is less than the diameter of return opening 5.The top described cavity 2 inwall being positioned at return opening 5 is provided with one for the pressure spring 9 ' of control presssure.
A time delay is provided with dull and stereotyped on the change speed gear box of described fork truck and between body, be respectively equipped with the asphalt channel be connected with change speed gear box advance gear, backing car gear, parking gear oil circuit in described time delay flat board, described each asphalt channel is connected with oil inlet, return opening respectively.The currency of oil body can be extended like this, thus the moment vibration produced when reducing shift.
When clutch coupling device is in static, oil inlet, return opening are in connected state.When arrangement of clutch will change gear, oil body is entered by oil inlet, and part oil body enters time delay oil pocket, part oil body passes back into oil circuit from return opening, part oil body enters in arrangement of clutch, and less owing to entering the oil body that arrangement of clutch gathers, the state of gearshift can not be carried out immediately.When the oil body entering time delay oil pocket is abundant, oil body will promote first piston and move to right, thus promotion the second piston moves to right, until blocking return opening, now, the oil body entered by oil inlet will enter in arrangement of clutch and time delay oil pocket.Due to the reason of pressure, second piston is difficult to move to right to cavity right side wall and fits, and due to the existence of step, makes the mobile restricted of first piston, and the movement of the second piston be connected by spring with first piston is limited too, thus power-transfer clutch oil inlet can not be blocked.When the oil body entering arrangement of clutch is abundant, clutch gear-shift success, now oil inlet stops oil-feed, and the impact that is stressed, the oil body of time delay oil pocket flows backwards, thus the second piston moves to left, and return opening is opened.
And spring is set between first piston and the second piston, can prevent from making when oil pressure is excessive, the unexpected oil-feed of oil inlet causes the pressure of time delay oil pocket excessive, instantaneous extruding first piston, instantaneous blocking return opening, make an elastomeric surge time of this process, when on the right side of oil body is full of cavity, this process also can slow down because of the existence of oil body on the right side of cavity.
