  • the unit 100 Compared to when the second gear 32 rotates integrally with the rotating shaft 23 of the rotating electric machine 20, the unit 100 differs in that the output of the rotating electric machine 20 is reduced in two stages before being transmitted to the second gear 32. In other words, the unit 100 can be set to a large reduction ratio, making it possible to design the rotating electric machine 20 to have a smaller maximum torque, and thus making it possible to reduce the size of the rotating electric machine 20.

  • the protrusion of the gears is suppressed and the radial dimension of the unit 100 can be reduced compared to when the gears do not overlap with the rotating electric machine 20 in the axial view.
  • this contributes to the radial miniaturization of the unit 100.
  • the width of the installation space in the left-right direction of the vehicle becomes a constraint. With the unit 100, such a constraint can be overcome by miniaturizing the radial direction corresponding to the left-right direction of the vehicle.
  • the rotating electric machine 20 and the first gear 31 have a portion sandwiched between the second gear 32 and the sixth gear 36 in the axial direction (a portion sandwiched between portion S1 and portion S2).
  • the first gear 31, the second gear 32, and the sixth gear 36 are arranged in a dispersed manner on both axial sides of the rotating electric machine 20. This makes it easier to design the support walls and bearings provided in the housing 10 in a reasonable arrangement compared to a case in which they are densely arranged on one axial side of the rotating electric machine 20, and increases the design freedom of the layout of the unit 100 itself.
  • the axis of the first axis AX1 is offset from the axis of the third axis AX3.
  • the axis of the first axis AX1 and the axis of the third axis AX3 do not overlap (are offset) when viewed in the axial direction.
  • the rotating electric machine 20 is arranged on the first axis AX1. Therefore, the axis of the rotating electric machine 20 is offset from the axis of the second gear 32 and the sixth gear 36 arranged on the third axis AX3.
  • the axes of the first axis AX1, the second axis AX2, and the third axis AX3 are arranged in a V-shape when viewed in the axial direction.
  • the axis of the first axis AX1 is located at a position that is off the imaginary line that connects the axis of the second axis AX2 and the axis of the third axis AX3.
  • an imaginary triangle is formed with the axis of the first axis AX1, the axis of the second axis AX2, and the third axis AX3 as vertices. It can also be said that the axis of the first axis AX1, the axis of the second axis AX2, and the third axis AX3 are not aligned on a straight line.
  • the axis of the rotating electric machine 20 by aligning the axis of the rotating electric machine 20 with that of the second gear 32 and the sixth gear 36, the axis of each can be arranged in a straight line when viewed in the axial direction, so it is possible to minimize the protrusion of the gears.
  • the rotary electric machine 20 and the second gear 32 and sixth gear 36 are offset in axis, which removes such restrictions and improves design freedom. Even with such offset axis, it is still possible to miniaturize unit 100 to a certain extent, such as to the extent necessary for installation in a converted EV.

This portion is formed in a ring shape around the stepped portion of the rotating shaft 23, and the resolver 40 axially overlaps with the rotor 21 and part of the rotating shaft 23 of the rotating electric machine 20 at this portion, and also overlaps with the second gear 32 in the axial direction.
  • the resolver 40 is also arranged together with the second gear 32 on the opposite side of the rotor 21 of the rotating electric machine 20 from the first gear 31 side in the axial direction.
  • the resolver 40 is placed on the opposite side of the first gear 31 in the axial direction, where the first gear 31 that connects to the rotating electric machine 20 is located, reducing the available space in the unit 100, and the resolver 40 is placed on the opposite side, together with the second gear 32, so that the space on the opposite side is effectively utilized.
  • the second gear 32 is arranged close to the resolver 40.
  • the resolver 40 detects the rotation angle of the rotating electric machine 20 using magnetism, as described below. For this reason, if the second gear 32 is arranged close to the resolver 40, there is a concern that the magnetic field of the resolver 40 will change due to the influence of the rotation of the second gear 32, such as the magnetic field lines of the resolver 40 being disturbed by the rotation of the second gear 32, which may affect the detection of the rotation angle of the resolver 40.

  • a gap G is formed between the resolver rotor 41 and the resolver stator 42, and multiple recesses and protrusions are evenly spaced around the circumference of the resolver rotor 41. Therefore, the spacing of the gap G changes periodically with the rotation angle of the resolver rotor 41.
  • the outer diameter of the resolver rotor 41 can be set to change gradually around the circumference, that is, the outer circumference changes smoothly around the circumference.
  • the resolver coil has an excitation coil and an output coil, and when the gap G changes in response to the rotation of the resolver rotor 41 while excited by the excitation coil, the magnetic permeability also changes. As a result, the output voltage of the output coil changes. Therefore, the rotation angle of the resolver rotor 41 is detected based on the output voltage of the resolver 40, and the rotation angle of the rotating electric machine 20 is detected using magnetism.
  • the unit 100 further has a shield member 50.
  • the shield member 50 is a magnetic shield member that provides magnetic shielding, and is preferably made of, for example, a ferromagnetic material. Examples of materials that make up a ferromagnetic material include materials whose main components are iron, cobalt, and nickel.

  • the shield member 50 axially overlaps the resolver 40 and the second gear 32 in this portion, and is disposed between the resolver 40 and the second gear 32 in the axial direction. Therefore, even if the second gear 32 disposed near the resolver 40 rotates, the shield member 50 provides a magnetic shield between the second gear 32 and the resolver 40, so that the magnetic field of the resolver 40 is prevented from changing due to the influence of the rotation of the second gear 32.
  • the influence of the rotation of the second gear 32 on the magnetic field of the resolver 40 is large when the second gear 32 is made of, for example, a ferromagnetic material.
  • the second gear 32 has an annular protrusion 32a that protrudes toward the rotating electric machine 20, i.e., on one axial side.
  • the annular protrusion 32a is formed on the outer periphery of the second gear 32 and protrudes on one axial side compared to the surface that is radially inward from the outer periphery.
  • the shield member 50 has a portion located radially inside the annular protrusion 32a (the portion on the other axial side from axial position X1, which is the end face position on one axial side of the second gear 32 shown in FIG. 4).
  • the shield member 50 in the unit 100, it is possible to position the second gear 32 and the resolver 40 closer together than in the case where the shield member 50 is not provided. This also shortens the axial length of the unit 100.

  • the reason for providing the bearing 60 and the wall portion 10a in this manner is as follows.
  • the rotating electric machine 20 is also one of the elements that affect the magnetic field of the resolver 40, and the influence of the rotating electric machine 20 tends to be greater than that of the second gear 32. Therefore, the influence of the rotating electric machine 20 is reduced by providing a distance between the resolver 40 and the bearing 60, and is further reduced by shielding it with the wall 10a. It is preferable that the wall 10a is made of a ferromagnetic material, for example.

  • a shield member 50 is interposed between the resolver 40 and the second gear 32, so that the magnetic field of the resolver 40 can be prevented from changing due to the influence of the rotation of the second gear 32. Therefore, the influence of the rotation of the second gear 32 on the resolver 40 is reduced. From another perspective, it can also be said that since the influence of the rotation of the second gear 32 on the resolver 40 can be reduced, it is possible to bring the second gear 32 and the resolver 40 as close as possible.
