And because the front shell 1 is a seamless component with an integrated structure, the power takeoff structure is equivalent to integrating a power takeoff shell and a transmission shell into a common shell, and has the characteristics of compact integral structure, small occupied space, high transmission efficiency and low cost.
Moreover, because the power take-off shaft 6 and the transmission input shaft 23 are arranged in the front shell 1 of the integrated structure side by side and are rotatably connected with the front shell 1, the joint of the rear shell 26 and the front shell 1 is far away from the position where the power take-off driven gear 2 is meshed with the power take-off driving gear 24, so that the connection strength of the joint of the front shell and the rear shell is influenced in the dynamic connection process of the gear meshing position, and the oil leakage risk is avoided.

In specific implementation, in the power take-off structure, the second side surface 112 of the front shell 1 is provided with a second opening 102 for installing the output end of the power take-off shaft 6. As shown in fig. 1, the output end of the power take-off shaft 6 is located within the second opening 102. At this time, the output end of the power take-off shaft 6 and the input end of the transmission input shaft 23 are located on both sides of the housing, respectively.
Alternatively, in other embodiments, an opening for mounting the output end of the power take-off shaft 6 may be provided on the first side 111. At this time, the output end of the power take-off shaft 6 is located on the same side of the housing as the input end of the transmission input shaft 23.
Specifically, a first bearing 9, a sealing structure and a circlip 3 are arranged between the output end of the power take-off shaft 6 and the inner wall of the second opening 102, wherein: the sealing structure is positioned between the power take-off shaft 6 and the inner wall of the second opening 102 and is closer to the outer side of the shell relative to the first bearing 9; the elastic retainer ring 3 is positioned in an annular groove formed in the inner wall of the second opening 102, and is closer to the outer side of the shell relative to the sealing structure, and the elastic retainer ring 3 is used for axially positioning the oil seal seat ring 5.
Specifically, the sealing structure comprises an oil seal 7, an oil seal seat ring 5 and a first sealing ring 4. Wherein: the output end of the power take-off shaft 6 is sealed by the oil seal 7, and the oil seal 7 is closer to the outer side of the shell relative to the first bearing 9; the oil seal seat ring 5 is sleeved outside the oil seal 7, namely the oil seal 7 is arranged in the oil seal seat ring 5; the first sealing ring 4, in particular an O-ring, is located between the oil sealing seat ring 5 and the inner wall of the second opening 102. Further, an adjusting gasket 8 is arranged between the elastic retainer ring 3 and the oil seal seat ring 5, and the adjusting gasket 8 is used for adjusting the axial side clearance of the first bearing 9.
Wherein, one end of the power take-off shaft 6 is rotatably mounted in the second opening 102 of the second side surface 112 of the front shell 1 through the first bearing 9, and the other end is rotatably mounted in the positioning groove of the first side surface 111 of the front shell 1 through the second bearing 19. Thus, as shown in fig. 1, the power take-off shaft 6 is provided with the circlip 3, the adjustment washer 8, the seal structure, the first bearing 9, the inner race 10, the power take-off gear 2, the hub 21, and the second bearing 19 in this order in the axial direction, and the needle bearing 18 is provided between the power take-off gear 2 and the power take-off shaft 6. Wherein, one end of the power take-off driven gear 2 and the first bearing 9 are axially positioned through an inner retainer ring 10, and the other end of the power take-off driven gear is abutted against a gear hub 21; one end of the gear hub 21 is limited by a shaft shoulder of the power take-off shaft 6, and the other end of the gear hub abuts against the second bearing 19.
Preferably, the first bearing 9 and the second bearing 19 may employ deep groove ball bearings. Furthermore, it is preferable that the power take-off driven gear 2 and the power take-off driving gear 24 are both cylindrical helical gears, i.e., a pair of cylindrical helical gears is used to transmit torque between the power take-off shaft 6 and the transmission input shaft 23.
Preferably, the power take-off driving gear 24 is in interference fit with the transmission input shaft 23, and the structure is compact and the axial space is small.
Preferably, the output end of the power take-off shaft 6 is provided with an internal spline; and/or the power take-off shaft 6 is a hollow shaft, and a shaft hole is blocked by a bowl-shaped plug 20 to prevent oil leakage.
Furthermore, the power take-off structure also comprises a clutch mechanism for controlling the power take-off driven gear 2 to synchronously rotate or disengage with the power take-off shaft 6. The clutch mechanism can be used when the vehicle runs or stops.
With particular reference to fig. 1, the power take-off gear 2 is provided with a second ring gear 202, the second ring gear 202 and the first ring gear 201 being arranged axially side by side. The clutch mechanism comprises a piston shaft 12, a gear hub 21, a sliding sleeve 22, a shifting fork 13, a return spring 11 and a signal switch 17. Wherein: the piston shaft 12 is arranged in the shell and is parallel to the power take-off shaft 6; the gear hub 21 is coaxially connected with the power take-off shaft 6 and is adjacent to the second gear ring 202; the sliding sleeve 22 is sleeved outside the gear hub 21 and meshed with the gear hub; one end of the shifting fork 13 is fixedly connected with the piston shaft 12, and the other end is connected with the sliding sleeve 22, and is used for controlling the sliding sleeve 22 to be meshed with or separated from the second gear ring 202.
If the piston shaft 12 moves forward (see the vertical upward big arrow in fig. 1), the shifting fork 13 is driven to move forward, so that the shifting fork 13 controls the sliding sleeve 22 to move forward along the axial direction until the sliding sleeve 22 is meshed with the second gear ring 202 of the power take-off driven gear 2, at this time, because the internal spline (or called internal tooth) of the sliding sleeve 22 is meshed with the gear hub 21 and the second gear ring 202 simultaneously, the power take-off shaft 6 and the power take-off driven gear 2 rotate synchronously, and power is transmitted to the power take-off shaft 6 from the transmission input shaft 23, so that power take-off is realized.
If the piston shaft 12 moves in the reverse direction (see the vertical downward large arrow in fig. 1), the shifting fork 13 is driven to move in the reverse direction, so that the shifting sleeve 22 is controlled by the shifting fork 13 to move in the reverse direction along the axial direction until the shifting sleeve 22 is separated from the second ring gear 202 of the power take-off driven gear 2, at this time, as the driven gear 2 is rotatably connected with the power take-off shaft 6 (i.e., the power take-off driven gear 2 is rotatably sleeved on the power take-off shaft 6 relatively), the power take-off shaft 6 does not rotate along with the power take-off driven gear 2, and the power transmission is interrupted.
Specifically, the hub 21 is splined to the power take-off shaft 6 for synchronous rotation therewith.
Specifically, the signal switch 17 is located axially outside the driving end of the piston shaft 12. When the piston shaft 12 moves reversely and the sliding sleeve 22 is separated from the second gear ring 202 of the power take-off driven gear 2, the end face of the piston shaft 12 contacts with the signal switch 17, so that the signal switch 17 is triggered, and the working state of the power take-off is displayed on the display screen through the traveling computer. It can be seen that when the piston shaft 12 is axially returned, it is directly pressed to the contact of the signal switch 17, and there is no friction between the contact and the piston shaft, so that the contact is not easy to wear and is not stressed by radial force.
In a preferred embodiment, a third opening 103 is disposed at a position corresponding to the piston shaft 12 on the first side surface 111 of the front housing 1, and the driving end of the piston shaft 12 is connected to an inner wall of the third opening 103 in a sealing manner by a second sealing ring 15 and can move axially relative to the third opening 103, so that the third opening 103 corresponds to a cylinder body of an air cylinder, which is also called a cylinder bore. An air cylinder rear cover 16 is arranged outside the third opening 103, and an air passage for controlling the axial expansion of the piston shaft 12 is arranged in the air cylinder rear cover 16. Furthermore, the signal switch 17 is installed on the cylinder rear cover 16, separated from the transmission oil, and thus has a long service life.
Furthermore, the third opening 103 of the front shell 1 is embedded with a copper sleeve 14, so that the friction of the piston shaft 12 can be reduced.
Specifically, the return spring 11 is sleeved outside the piston shaft 12. The inner wall of the second side surface 112 of the front shell 1 is provided with a positioning blind hole matched with the positioning end of the piston shaft 12 and a stepped hole for installing the return spring 11; one end of the return spring 11 is abutted against the second side surface 112, and the other end is abutted against the shifting fork 13, and is used for controlling the piston shaft 12 to move reversely and return.
In conclusion, the working process of the power take-off structure is as follows:
when the air passage in the cylinder rear cover 16 is ventilated, the pressure in the cavity between the end face of the piston shaft 12 and the cylinder rear cover 16 is large, so that the piston shaft 12 is pushed to move forward along the axial direction, the shifting fork 13 moves along with the piston shaft 12, and then the sliding sleeve 22 is driven to move and then meshed with the power take-off driven gear 2. At this point, power is transmitted from the transmission input shaft 23 to the power take-off shaft 6 and the power take-off arrangement begins to operate. At this time, the piston shaft 12 releases the contact of the signal switch 17, and the signal switch 17 is closed to send out a signal.
When an air passage in the cylinder rear cover 16 is not ventilated, the return spring 11 props against the shifting fork 13 and the piston shaft 12 to control the piston shaft 12 to move reversely until the driving end of the piston shaft 12 props against a contact of a signal switch 17 arranged on the cylinder rear cover 16. At this moment, the signal switch 17 is in a closed state, the shifting fork 13 pushes the sliding sleeve 22 to be separated from the driven gear 2, and the output end of the power take-off shaft is an internal spline which can be directly connected with the oil pump.
Furthermore, the embodiment of the present invention provides a transmission, and the transmission is provided with the above-mentioned power take-off structure.
