It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.

As shown in Figures 1 to 4, the disclosure provides a kind of transmission device, including driving shaft 3 ' and driven shaft 4 ', driving shaft 3 ' It is connected to driven shaft 4 ' by transmission mechanism, transmission mechanism includes the first transmission mechanism 1 and the second transmission mechanism 2, the first transmission The transmission ratio of mechanism 1 is different from the transmission ratio of the second transmission mechanism 2.Above-mentioned transmission device further includes being somebody's turn to do by control 5 by control It can selectively be made transmission device that there is the first working condition and the second working condition by the movement of control 5, in the first work State, driving shaft 3 ' drive driven shaft 4 ' by the first transmission mechanism 1, and in the second working condition, driving shaft 3 ' is passed by second Motivation structure 2 drives driven shaft 4 '.I.e. in the disclosure, can by control by control 5 switch driving shaft 3 ' and driven shaft 4 ' it Between transmission ratio, it is simple and easy.

Specifically, in the optional embodiment of the disclosure, in the first working condition, by control 5 and the first transmission mechanism 1 Engagement, so that driving shaft 3 ' drives driven shaft 4 ' by the first transmission mechanism 1, the second transmission mechanism 2 is relative to driving shaft 3 ' Dally with driven shaft 4 ', in the second working condition, by control 5 and the disengaging of the first transmission mechanism 1, the first transmission mechanism 1 relative to Driving shaft 3 ' and driven shaft 4 ' dally, and driving shaft 3 ' drives driven shaft 4 ' by the second transmission mechanism 2.Here, " idle running " refers to It is that the first transmission mechanism 1 or the second transmission mechanism 2 only operate between driving shaft 3 ' and driven shaft 4 ', but the torque of driving shaft 3 ' Driven shaft 4 ' can not be transferred to by the first transmission mechanism 1 or the second transmission mechanism 2 and driven shaft 4 ' is driven to rotate.Namely It says, in above-mentioned first working condition, the power of driving shaft 3 ' only passes through the first transmission mechanism 1 and is transferred to driven shaft 4 ', driven shaft 4 ' revolving speed is determined by the transmission ratio of the first transmission mechanism 1, and in above-mentioned second working condition, the power of driving shaft 3 ' only passes through Two transmission mechanisms 2 are transferred to driven shaft 4 ', and the revolving speed of driven shaft 4 ' is determined by the transmission ratio of the second transmission mechanism 2.In this way, due to First transmission mechanism 1 and the second transmission mechanism 2 can dally relative to two axis, therefore be not required to especially change two transmission mechanisms Position relative to two axis, it is only necessary to the switching that can realize different working condition is moved by control 5, so that the disclosure mentions The structure of the transmission device of confession is simpler reliable.In other possible embodiments, in the first working condition, the second transmission Mechanism 2 can stall, and in the second working condition, the first transmission mechanism 1 can also be stalled, and the mesh of the disclosure also may be implemented in this way 's.

Through the above technical solutions, the transmission device that the disclosure provides optionally is driven by the first transmission mechanism 1 Or second transmission mechanism 2 drive, make the transmission ratio of transmission device can be in the transmission ratio and the second transmission mechanism of the first transmission mechanism 1 Switch between 2 transmission ratio, since the transmission ratio of the first transmission mechanism 1 is different from the transmission ratio of the second transmission mechanism 2, driven shaft 4 ' revolving speed in the first operative state is also just different from its revolving speed in a second operative state, to realize driven shaft 4 ' Revolving speed is adjustable.

This kind of transmission side that driving shaft 3 ' drives driven shaft 4 ' to rotate all is applied in machinery field, many mechanical equipments Formula, therefore, the transmission device that the various embodiments of the disclosure can be provided are applied in this kind of mechanical equipment, make such machinery The component connected in equipment from driven shaft 4 ' can have different operating conditions.For example, as a kind of application implementation mode, in this public affairs In opening, transmission device can be by application engine, and the drive shaft 3 in engine for driving lubricating oil pump to operate is (for example, crankshaft Or balance shaft) it is equivalent to above-mentioned driving shaft 3 ', machine oil pump shaft 4 is equivalent to above-mentioned driven shaft 4 ', in this way, at 3 turns of drive shaft In the case where fast certain, by adjust the actual condition that can be made the revolving speed of lubricating oil pump axis 4 by control 5 according to engine into Row adjustment, thus enable the oil drain quantity of lubricating oil pump according to low engine speed rotation and different machine oil demands when high-speed rotation into Row is adaptively adjusted, and in favor of reducing the power loss of lubricating oil pump, avoids the waste of machine oil.

In a kind of illustrative embodiments that the disclosure provides, as depicted in figs. 1 and 2, it can axially move by control 5 And be circumferentially mounted on driving shaft 3 ' or driven shaft 4 ' to locking, the first transmission mechanism 1 can be two-way by the first mounting structure It is mounted between driving shaft 3 ' and driven shaft 4 ' with lost motion, the second transmission mechanism 2 can unidirectionally with lost motion by the second mounting structure It is mounted between driving shaft 3 ' and driven shaft 4 ', in the first working condition, is engaged by control 5 with the first transmission mechanism 1, driving shaft 3 ' drive driven shaft 4 ' to rotate by the first transmission mechanism 1, and the second transmission mechanism 2 is by the second mounting structure relative to driving shaft 3 ' dally with driven shaft 4 ', in the second working condition, are detached from by control 5 and the first transmission mechanism 1, driving shaft 3 ' is passed by second Motivation structure 2 drives driven shaft 4 ' to rotate, and the first transmission mechanism 1 is by the first mounting structure relative to driving shaft 3 ' and driven shaft 4 ' Idle running.Herein, " bidirectional idling " although referring to operating, the first transmission mechanism 1 can neither be transmitted from driving shaft 3 ' to driven shaft 4 ' Torque can not transmit torque from driven shaft 4 ' to driving shaft 3 ', " unidirectional idle running " although referring to operating, the second drive mechanism 2 It is only capable of transmitting torque from driving shaft 3 ' to driven shaft 4 ', but torque can not be transmitted from driven shaft 4 ' to driving shaft 3 '.For example, when from When the actual speed of moving axis 4 ' is less than the revolving speed that driven shaft 4 ' drives according to the transmission ratio of the second transmission mechanism 2, driving shaft 3 ' can To transmit torque to driven shaft 4 ' by the second transmission mechanism 2, but driven shaft 4 ' can not be by the second transmission mechanism 2 to driving shaft 3 ' transmitting torques.

That is, being engaged by control 5 with the first transmission mechanism 1 in the first working condition, due to by the circumferential lock of control 5 It only is mounted on driving shaft 3 ' or driven shaft 4 ', is rotated synchronously by control 5 with driving shaft 3 ' or driven shaft 4 ', the first driver Structure 1 realizes the work of transmitting torque (between driving shaft 3 ' and driven shaft 4 ' by that can be released bidirectional idling state by control 5 Torque pass through engaged by control 5), at this point, since the second transmission mechanism 2 has the performance that unidirectionally dallies, even if Driving shaft 3 ' has driven the second transmission mechanism 2 to operate, and also can not transmit torque to driven shaft 4 ' by the second transmission mechanism 2, because This second transmission mechanism 2 will not interfere being driven between two axis by the first transmission mechanism 1 compared with large transmission ratio.For example, at this time The actual speed of driven shaft 4 ' can be greater than the revolving speed that driven shaft 4 ' drives according to the transmission ratio of the second transmission mechanism 2, the second transmission Mechanism 2 dallies, and works without influencing biggish first transmission mechanism 1 of transmission ratio.
