Specific embodiment
Below in conjunction with attached drawing 1, the present invention will be described in detail: the present invention includes at least two hydraulic cylinders 1, hydraulic cylinder 1 Between cooperate and be fixed together by respective cylinder wall, pass through combination formed an entirety hydraulic cylinder mechanism 2；Liquid The sides such as cylinder wall between cylinder pressure 1 and hydraulic cylinder 1 fixed by interference fit, bolt, detent fit, spline fitted or welding Formula is fixed together, wherein more the most commonly used is interference fits, is nested together isolated hydraulic cylinder 1 by external force.Hydraulic cylinder 1 Cylinder body in offer at least one oil pocket 1-1, and moveable piston 3 is installed in oil pocket 1-1；The cylinder wall of hydraulic cylinder 1 On offer the fuel feed hole 1-2 communicated with oil pocket 1-1, and fuel feed hole 1-2 at least offers one, and a pair of with oil pocket 1-1 mono- It should be distributed；The quantity of fuel feed hole 1-2 is equal with the quantity of oil pocket 1-1, can ensure that the oil pocket 1-1 in each hydraulic cylinder 1 is in this way Complete and mutually indepedent arrangement, has the advantages that without string oil, risk of leakage；It, can be with simultaneously in the case where meeting same functional requirement Save CSC arrangement space.
Combination among the above are as follows: when two hydraulic cylinders 1 are arranged, in oil pocket quantity can be 1/1,2/2,2/3 It is arranged Deng such mode；When three hydraulic cylinders 1 are arranged, in oil pocket quantity can for 2/2/2,2/2/3,2/3/3 etc. this The mode of sample is arranged.
Hydraulic cylinder 1 is preferably rotation body structure, and is connected between hydraulic cylinder 1 and hydraulic cylinder 1 by concentric mode, i.e., The axis line location of the axial line of one hydraulic cylinder 1 and another hydraulic cylinder 1 is on same straight line, and the concentric mode connects only The connection being limited between two hydraulic cylinders 1.
Hydraulic cylinder 1 is preferably rotation body structure, and is connected between hydraulic cylinder 1 and hydraulic cylinder 1 by Under Asymmetrical mode, i.e., The axial line of one hydraulic cylinder 1, in parallel distribution, and mutually disjoints, and the off-axis with the axis line location of another hydraulic cylinder 1 Heart mode is connected suitable for the connection between two or more hydraulic cylinders 1.
Embodiment: it such as sets there are three hydraulic cylinder 1, adoptable mode is by the concentric mode phase of two of them hydraulic cylinder 1 Connection, remaining one is connected with other two using the hydraulic cylinder 1 that concentric mode is connect using Under Asymmetrical mode；Or three It is connected between a hydraulic cylinder 1 using Under Asymmetrical mode；Two kinds of above-mentioned connection types can be according to the spatial position CSC in clutch Connection type is arranged and adjusted to required size, have flexible arrangement, it is compact-sized, can save arrangement space, give clutch Device Miniaturization Design is brought convenience.
Embodiment: separate type concentric servo hydraulic cylinder mechanism includes two hydraulic cylinders 1, the intracorporal oil pocket of the cylinder of hydraulic cylinder 1 There are two 1-1 is opened up, and in mutually indepedent distribution between oil pocket 1-1；Concentric mode or off-axis are used between two hydraulic cylinders 1 Heart mode is connected, and is fixed between cylinder wall by interference fit, bolt, the modes such as detent fit, spline fitted or welding It fixes together.
Oil inlet mode one: as shown in Fig. 2, being extended with convex block 4 on the cylinder wall of hydraulic cylinder 1, offers in convex block 4 and oil The fuel feed hole 1-2 that chamber 1-1 is communicated；Convex block 4 is equipped with one or more, i.e., when convex block 4 sets one, at this point, in the convex block 4 On offer the fuel feed hole 1-2 equal with the intracorporal oil pocket 1-1 quantity of the cylinder of hydraulic cylinder 1；When more than one is arranged in convex block 4, At this point, the intracorporal oil pocket 1-1 quantity of the cylinder of hydraulic cylinder 1 is at least in two or more, and at least provided with an oil inlet in every piece of convex block 1 Hole 1-2；The quantity setting of the convex block 4 can according in clutch CSC it is different require and admissible spatial dimension in fitted When setting.
Oil inlet mode two: the oil pipe for fuel feeding is installed in fuel feed hole 1-2, i.e., is directly bored on the casing wall of hydraulic cylinder Oil pipe is stretched to the oil pipe that in hole or grafting is prefabricated by hole, and the processing is simple for this mode, and oil duct arrangement is also more convenient.
The operation principle of the present invention is that: as shown in Fig. 3, when the first oil pocket 1-11 is full of pressure oil, first piston 3-1 It is pushed by pressure oil, toward moving left, the first brake clutch 7 in the executing agency in left side can be pushed, made it combine or divide From (as shown in A in figure)；When the second oil pocket 1-12 is full of pressure oil, second piston 3-2 is pushed by pressure oil, past to move left, The second brake clutch 8 in the executing agency in left side can be pushed, makes it combine or separates (as shown in B in figure)；Work as third When oil pocket 1-13 is full of pressure oil, third piston 3-3 is pushed by pressure oil, toward moving right, by the first angular contact ball bearing 5, The first shift separation clutch 9 in the executing agency on right side is pushed, makes it combine or separates (as shown in C in figure)；When the 4th When oil pocket 1-14 is full of pressure oil, the 4th piston 3-4 is pushed by pressure oil, toward moving right, by the second angular contact ball bearing 6, The second shift separation clutch 10 in the executing agency on right side is pushed, makes it combine or separates (as shown by d in the figure)；It is above-mentioned to relate to And the first shift separation shift separation clutch 10 of clutch 9, second arrived is suitable for automatic gear-box or hybrid power speed change Case.
The above-mentioned oil pocket 1-1 being related to is the pressure oil cavity in hydraulic cylinder 1, and the fuel feed hole to match with oil pocket 1-1 1-2 is pressure oil fuel feed hole.
The present invention is not limited to the above-described embodiments, makees any variation no matter constituting in its shape or material, all to adopt It is designed with structure provided by the present invention, is all a kind of deformation of the invention, is considered as within that scope of the present invention.
