[0004] A claw-type shifting device is used to disconnect and / or close a shiftable connection. In this document, "shiftable connection" specifically refers to a connection in a mechanical power path that allows shifting between an open shifting position (where the mechanical power path is separated and mechanical power flow cannot pass through the connection) and a closed shifting position (where the mechanical power path is closed and mechanical power flow can pass through the connection). In this document, "shifting" specifically refers to disconnecting or closing a shiftable connection and / or changing between an open shifting position and a closed shifting position. Mechanical power includes, in particular, torque and / or angular velocity.
[0005] A shift sleeve is particularly a mechanical element used as a shifting element for shifting at least one shiftable connection. The shift sleeve may have an actuation section for applying actuating force to the shift sleeve, a first connection section for connection to a first machine element, and at least one additional connection section for connection to at least one other machine element. The connection section of the shift sleeve may be toothed. The tooth may be axially movable. The machine element that can be connected by means of the shift sleeve may be a shaft, gear, and / or housing. The shift sleeve may be movable between at least two shift positions. The shift sleeve may be anti-rotatably connected to and movable along a shaft.
[0006] The claw shift mechanism, the first shift sleeve, the connecting element, and the first shaft may share a common axis. The first shift sleeve may be movable along this axis. Unless otherwise stated or indicated in the context, the terms "axial," "radial," and "circumferential direction" refer to the direction in which the axis extends. "Axial" thus corresponds to the direction in which the axis extends. "Radial" thus is the direction perpendicular to and intersecting the direction in which the axis extends. "Circumferential direction" thus corresponds to the direction of an arc about the axis. The axis may be a rotational axis and / or a linear axis. The term "first shift sleeve" does not imply that another shift sleeve must also exist herein.
[0007] The first shift sleeve may extend over a larger axial region than the connecting element. The first shift sleeve may have a sleeve-like, tubular, or hollow cylindrical shape. The first shift sleeve may have axial sections with different outer diameters.

The first shift sleeve and the connecting element may be axially arranged sequentially on the first shaft. The connecting element may be arranged on the central section of the first shift sleeve. The first shift sleeve and the connecting element may each be directly arranged on the first shaft. "Directly" in this context specifically means that no other machine element is arranged between the first shift sleeve and the connecting element (on one hand) and the first shaft (on the other hand).
[0012] The first shift sleeve can be shiftable between a first shift position where the connection between the first shaft and the housing is closed, a second shift position where the connection is detachable, a third shift position where the connection between the first shaft and the second shaft is closed, a fourth shift position where the connection is detachable, and / or a fifth shift position where the connection between the first shaft and the third shaft is closed.

[0015] The through-joint can be configured to have clearance. The through-joint can be adjusted to be unloaded at the first shift position of the second shift sleeve, enabling axial movement of the first shift sleeve for shifting. Thus, the through-joint can be adjusted to be unloaded, i.e., so that no mechanical power flows through the first shift sleeve.
[0016] The second shift sleeve can be mounted on the first shift sleeve. The second shift sleeve can be axially movable and / or rotatably mounted on the first shift sleeve.

[0019] This drive mechanism can be used to drive motor vehicles. The mechanical power path can be used to transmit traction drive power and / or support mechanical power during power shifting. In this document, "power shifting" specifically refers to changing gears in the transmission without interrupting traction or when traction loss is reduced.
[0020] The drive mechanism may have a first drive machine and a second drive machine. The at least one drive machine may be an electric motor. The electric motor may have a stator and a rotor. The electric motor may be operable as a motor and / or generator. The transmission may have gear stages. The gear stages may have different gear ratios.

By means of the claw shifter, the gear stages of the transmission may be power-shiftable. By means of a connecting element, mechanical output power can be supported on the first drive machine during gear shifting. The first shaft, the second shaft, and the third shaft may be mounted among each other. The first shaft may be mounted in the second shaft. The second shaft may be mounted in the third shaft. The first shaft can be implemented as a hollow shaft or a solid shaft. The second and third shafts can be implemented as hollow shafts. Each of these shafts has an end located on the side of the claw shifter. The ends of the shafts are arranged in axial order, so that each shaft is accessible in the radial direction.
[0021] The first shift sleeve, connecting element, and first shaft are interconnected in a rotation-resistant manner and can all rotate about a common axis. The first shift sleeve can be axially movable relative to the connecting element and the first shaft to facilitate gear shifting.

[0023] In summary, and in other words, the present invention primarily relates to a claw-type shifting device having through-joints for assisting shifting.

The diameter of the first shift sleeve undergoes a sudden change for accommodating the connecting element.
[0024] This invention enables gear shifting while a mechanical power flow exists. It achieves structural and functional integration. It allows the mechanical power flow that crosses through the first shift sleeve to pass through the first shaft. Attached Figure Description

[0068] The drive machine is an electrically driven machine. The transmission 4 has a first shaft 7, a second shaft 8, and a third shaft 9 forming the transmission input, and a transmission output 10. The transmission 4 includes, for example, a first planetary gear set 11 having a sun gear, a planet carrier, and a ring gear, and a second planetary gear set 12 having a sun gear, a planet carrier, and a ring gear. The first shaft 7 drives the sun gear of the second planetary gear set 12, the second shaft 8 drives the planet carrier of the first planetary gear set 11 and the ring gear of the second planetary gear set 12, and the third shaft 9 drives the sun gear of the first planetary gear set 11. The first shaft 7 is mounted in the second shaft 8. The second shaft 8 is mounted in the third shaft 9. Shafts 7, 8, and 9 each have an end located on the side of the claw shifter. The ends of shafts 7, 8, and 9 are arranged in axial order, so that these shafts are each accessible in the radial direction.
[0069] The claw-type shifting device 5 includes: a first clutch element 13, a second clutch element 14, a third clutch element 15 and a fourth clutch element 16, a first shifting sleeve 17, a second shifting sleeve 18, and a connecting element 19.
[0070] The first clutch element 13 is anti-rotatably and axially fixedly connected to the first shaft 7, and is used to enable the connection between the first shift sleeve 17 and the first shaft 7. The second clutch element 14 is anti-rotatably and axially fixedly connected to the second shaft 8, and is used to enable the connection between the first shift sleeve 17 and the second shaft 8. The third clutch element 15 is anti-rotatably and axially fixedly connected to the third shaft 9, and is used to enable the connection between the first shift sleeve 17 and the third shaft 9. The fourth clutch element 16 is anti-rotatably and axially fixedly connected to the third shaft 9, and is used to enable the connection between the second shift sleeve 18 and the third shaft 9.
[0071] The first shift sleeve 17 is shiftable between a first shift position where the connection between the first shaft 7 and the housing 6 is closed, a second shift position where the connection is open, a third shift position where the connection between the first shaft 7 and the second shaft 8 is closed, a fourth shift position where the connection is open, and a fifth shift position where the connection between the first shaft 7 and the third shaft 9 is closed, by means of the first actuator 20. Alternatively, the shift sleeve 17 can be operated only in the three shift positions where a connection is established between the two components.
[0072] The second shift sleeve 18 is shiftable between a first shift position where the connection between the first drive machine 2 and the first shaft 7 is closed, a second shift position where the connection is separated, and a third shift position where the connection between the first drive machine 2 and the third shaft 9 is closed, by means of the second actuator 21.
[0073] The connecting element 19 is anti-rotatable and axially fixed to the first shaft 7. The first shift sleeve 17 and the connecting element 19 are interlocked, so that mechanical power can flow through the connecting element 19 by means of the interlocking part 22, and the first shift sleeve 17 can be adjusted and moved axially without load for shifting.

The first clutch element 13, the second clutch element 14, the fourth clutch element 16, the first shift sleeve 17, the second shift sleeve 18, and the connecting element 19 can be seen. The third clutch element 15 is not shown here. Figure 3 The first shift sleeve 17, connecting element 19, first clutch element 13, second clutch element 14, and fourth clutch element 16 of the claw shift device 5 are shown in a perspective view.

[0077] The first axial section 26 of the first shift sleeve 17 has a smaller outer diameter suitable for receiving the connecting element 19, which corresponds with the inner diameter of the connecting element 19 at the connecting plate section 36 in a clearance manner. The second axial section 27 of the first shift sleeve 17 has a larger outer diameter, which corresponds with the inner diameter of the connecting element 19 at the recess 35 in a clearance manner. The connecting plate section 32 of the first shift sleeve 17 passes through and engages with the recess 35 of the connecting element 18, and the connecting plate section 36 of the connecting element 19 passes through and engages with the recess 31 of the first shift sleeve 17.

The connecting element 19 is axially fixed and anti-rotatable to the first shaft 7. The first shift sleeve 17 is anti-rotatable to the first shaft 7 and is axially movable relative to the connecting element 19 and the first shaft 7. For this purpose, the length of the notch 31 of the first shift sleeve 17 in the axial direction corresponds at least to the shift travel between the first shift position and the fifth shift position.
[0079] The second shift sleeve 18 is tubular and has two connecting sections arranged in axial sequence. One connecting section is assigned to the first drive mechanism 2 and is implemented as an external gear, while the other connecting section is assigned to the connecting element 19 and the third shaft 9 and is implemented as an internal gear. The second shift sleeve 18 is mounted so that it is axially movable and rotatable relative to the first shift sleeve 17.

The fourth clutch element 16 is anti-rotatably and axially fixedly connected to the second shaft 8 and connected to the second drive mechanism 3, and corresponds to the connecting section of the second shift sleeve 17. Clutch elements 13, 14, and 16 can be structurally separate or integrated, and in particular, can be implemented as an integral part of the shaft.
[0081] The through joint 22 formed by the notch 31 and connecting plate section 32 of the first shift sleeve 17, and the notch 35 and connecting plate section 36 of the connecting element 19 is provided with clearance, and the through joint can be adjusted without load at the first shift position of the second shift sleeve 18 so as to realize the shifting of the second shift sleeve 18. At the same time, the mechanical output power is supported on the first drive machine 2 by means of the connecting element 19, so that the gear levels of the transmission device are power-shiftable.
