The structure, operation principle and advantageous effects of the solution of the present application will now be described in detail with reference to fig. 1 to 5.
The first embodiment:
referring to fig. 1 and 2, the present invention provides a single-engine transmission device including a base 4, a transmission shaft 1 supported on the base 4 so as to be rotatable with respect to the base 4, and a power input member and a power output member 3 disposed at both ends of the transmission shaft 1. In the present embodiment, the power output member 3 includes a primary pulley 32, a second pneumatic clutch 31, and an automatic clutch 33. The power input member transmits power input from the engine to the primary pulley 32, the second pneumatic clutch 31, and the automatic clutch 33 through the propeller shaft 1. Between the power input part and the power output part 3, a bearing assembly is provided, by which the transmission shaft 1 is rotatably supported on the base 4 so that the power of the engine is transmitted to the power output part 3 through the bearing assembly, which is used to counteract the shaking power generated by the power input part and the engine, thereby achieving the purpose of stably transmitting the power of the engine to the power output part 3.
The power input part comprises a first pneumatic clutch 2, and the first pneumatic clutch 2 drives the transmission shaft 1 to rotate synchronously when in work. The first pneumatic clutch 2 of the present embodiment is a pneumatic friction clutch, the working principle is referred to in patent document No. 201720897007.7, and the working state and the non-working state are prior art, which will not be described in detail herein. In the embodiment, the second rotor of the first pneumatic clutch 2 is connected to the transfer case of the engine to input power, and when the first pneumatic clutch 2 works, the second rotor drives the first rotor to rotate so as to drive the transmission shaft 1 to rotate. In the embodiment, power is input through the first pneumatic clutch 2, so that the power input of the engine cannot be directly transmitted to the power output part 3 through the transmission shaft 1, and the purpose of controlling the time of power input at any time is achieved.
The power output part 3 comprises a primary belt wheel 32, a second pneumatic clutch 31 and an automatic clutch 33, wherein the automatic clutch 33 is used for linking a fan, the primary belt wheel 32 is used for linking an oil pump, and the second pneumatic clutch 31 is used for linking the fan. The primary belt wheel 32 and the transmission shaft 1 rotate synchronously, the automatic clutch 33 and the transmission shaft 1 rotate synchronously at a preset rotation speed, and the second pneumatic clutch 31 and the transmission shaft 1 rotate synchronously to drive the water pump to work when working. The primary pulley 32 is disposed between the automatic clutch 33 and the second pneumatic clutch 31 in the axial direction. Wherein the primary pulley 32 rotates in synchronization with the propeller shaft 1 to enable the oil pump to be driven in synchronization with the operation of the first pneumatic clutch 2. The automatic clutch 33 may be a centrifugal clutch, and the automatic clutch 33 rotates synchronously with the transmission shaft 1 when the rotation speed of the transmission shaft 1 reaches a preset rotation speed. The working principle of the centrifugal clutch can refer to the centrifugal clutch with the application number CN 201910449777.9. The second pneumatic clutch 31 is a pneumatic dog clutch, and its working principle can refer to a clutch with application number CN201821619719.3 or a clutch with application number CN 201821619718.9. By arranging the primary pulley 32 between the centrifugal clutch (automatic clutch 33) and the second pneumatic clutch 31 (pneumatic dog clutch), the automatic clutch 33 does not directly interfere with the second pneumatic clutch 31 when switching between the operating state and the non-operating state, and the problem of unstable meshing due to interference does not occur.
The automatic clutch 33, the primary pulley 32, and the second pneumatic clutch 31 are arranged in this order in a direction away from the first pneumatic clutch 2. That is, the automatic clutch 33 (centrifugal clutch) is disposed at a position close to the bearing assembly, that is, at a position close to the bearing assembly on the drive shaft 1, and the stability of the end relatively distant from the bearing assembly is higher, so that the entire drive shaft 1 is not shaken to an excessive extent by the shake at the time of switching the centrifugal clutch between the operating state and the non-operating state.
With reference to fig. 1 and fig. 2, the transmission shaft 1 includes a first shaft segment 11 for being sleeved with the second pneumatic clutch 31 and a second shaft segment 12 for being sleeved with the primary pulley 32, a support ring 7 is disposed on the first shaft segment 11 or the second shaft segment 12, the primary pulley 32 and the pneumatic tooth clutch respectively abut against two end surfaces of the support ring 7 along the axial direction, and the support ring 7 is sleeved on the periphery of the transmission shaft 1. The support ring 7 is used for ensuring that the second pneumatic clutch 31 and the primary pulley 32 are not directly and completely positioned on the transmission shaft 1 in the axial direction, so that the axial machining precision of the transmission shaft 1 is not high, and the second pneumatic clutch 31 and the primary pulley 32 are not over-positioned in an assembling device. In this embodiment, the transmission shaft 1 includes a third shaft section 13 for receiving the bearing assembly, one end of the first rotor of the automatic clutch 33 in the axial direction abuts against an end surface of the third shaft section 13, and the other end of the first rotor abuts against the first rotor of the primary pulley 32. The first rotor of the primary pulley 32 is configured to be long in the direction of the automatic clutch 33 and to abut against the automatic clutch 33 so that the primary pulley 32 and the automatic clutch 33 do not interfere with each other when they are operated.
The support ring 7 is in clearance fit with the second shaft section 12, so that the support ring 7 cannot abut against the end edge of the second shaft section 12 when being matched with the second pneumatic clutch 31 and the main belt pulley 32 and mounted on the transmission shaft 1, and the technical problem of poor mounting due to over-positioning cannot occur. In the embodiment, a first pressing member 5 is disposed at the end of the transmission shaft 1, and is axially locked at the end of the transmission shaft 1 to abut against the end of the first rotor of the second pneumatic clutch 31, so as to cooperate with the third shaft section 13 to axially clamp the primary pulley 32, the second pneumatic clutch 31, the automatic clutch 33, and the support ring 7. The transmission shaft 1 further has a fourth shaft section 14 for sleeving the first pneumatic clutch 2, a second pressing member 6 is arranged at an end of the fourth shaft section 14, and the second pressing member 6 is axially locked at the end of the fourth shaft section 14 to abut against an end of the first rotor of the first pneumatic clutch 2, wherein when the first pneumatic clutch 2 is pressed between the second pressing member 6 and an end edge of the third shaft section 13, the second pressing member 6 is in clearance fit with the end of the fourth shaft section 14, so that the first pneumatic clutch 2 cannot have the technical problem of axial movement when the second pressing member 6 is fastened at the end of the fourth shaft section 14 due to dimensional errors in assembly or due to dimensional machining errors in the axial direction of the transmission shaft 1.
The bearing assembly may comprise two bearings axially juxtaposed and the two bearings can be tapered, cylindrical roller bearings. In a preferred embodiment, the bearing assembly comprises two tapered roller bearings arranged oppositely, so that the bearing assembly can bear radial force and simultaneously can transmit axial movement to the first pneumatic clutch 2 when the load transfer case drives the first pneumatic clutch 2 to work.
Second embodiment:
unlike the first embodiment, in the second embodiment, the power output member 3 includes two of the primary pulley 32, the second pneumatic clutch 31, and the automatic clutch 33. For example, there may be a combination of,
combination A: the power output part 3 includes a primary pulley 32 and a second pneumatic clutch 31.
Combination B: the power output part 3 includes a primary pulley 32 and an automatic clutch 33.
And (3) combination C: the power output part 3 includes a second pneumatic clutch 31 and an automatic clutch 33.
In the second embodiment, the power input part comprises a first pneumatic clutch 2, and the first pneumatic clutch 2 drives the transmission shaft 1 to rotate synchronously when in operation. In the combination a, the primary pulley 32 is disposed between the second pneumatic clutch 31 and the bearing assembly in the axial direction so that the second pneumatic clutch 31 communicates with the air supply device. In the combination B, the automatic clutch 33 is axially disposed between the bearing assembly and the primary pulley 32, so that when the automatic clutch 33 (centrifugal clutch) is switched between an operating state and a non-operating state, the shaking force in the radial direction is not increased by the installation of the automatic clutch 33 at the end of the transmission shaft 1. In the combination C, the automatic clutch 33 is axially disposed between the second pneumatic clutch 31 and the bearing assembly, so that when the automatic clutch 33 (centrifugal clutch) is switched between the operating state and the non-operating state, the shaking force in the radial direction thereof is not increased by the mounting on the end of the propeller shaft 1, which leads to the problem of the increase in the overall shaking of the propeller shaft 1.
In the combination a, a support ring 7 sleeved on the periphery of the transmission shaft 1 is arranged between the primary pulley 32 and the second pneumatic clutch 31, and the primary pulley 32 and the pneumatic tooth clutch respectively abut against two end faces of the support ring 7 along the axial direction.
Other characteristics not mentioned in the second embodiment may be the same as those of the first embodiment, and the alternative implementation and the advantages thereof may also be the same as those of the first embodiment, and thus are not described again.
The third embodiment:
in a third embodiment, the present invention provides an air-actuated friction clutch, which comprises a first rotor 21, a second rotor 22, a friction mechanism 25, and a cylinder mechanism 23, with reference to fig. 4 and 5.

The axial movable member 212 is pushed by the elastic member 27/elastic component away from the friction mechanism 25, so that the friction mechanism 25 is elastically reset, and the first rotor 21 is switched from the rotating state to the moving state. The elastic element 27 can be a compression spring.
The friction mechanism 25 comprises a copper substrate 251, a steel plate 252 and a disc-shaped elastic sheet. The copper substrate 251 is connected with the second rotor 22, the steel sheet 252 is connected with the inner ring 211, and the friction mechanism 25 elastically deforms the belleville spring when being compressed, so that friction transmission is realized between the copper substrate 251 and the steel sheet 252. When the friction mechanism 25 is not subjected to the axial thrust of the axial movable member 212, the belleville springs elastically return and move the copper substrate 251 and the steel plate 252 away from each other. The specific structure and the working principle thereof are conventional in the art, and are not described in detail herein.
