A first motor mounting cavity 411 is provided at the first end of the motor and electronic control housing 4, and a second motor mounting cavity 412 is provided at the second end of the motor and electronic control housing 4. The first motor mounting cavity 411 and the second motor mounting cavity 412 are coaxially arranged. The first motor 11 is mounted in the first motor mounting cavity 411, and the second motor 12 is mounted in the second motor mounting cavity 412, and is symmetrical with the first motor 11. The first reduction assembly 2 connects the first motor 11 and the first wheel end, so that the power of the first motor 11 can be transmitted to the first wheel end through the first reduction assembly 2. Similarly, the second reduction assembly 3 connects the second motor 12 and the second wheel end, so that the power of the second motor 12 can be transmitted to the second wheel end through the second reduction assembly 3.

[0028] The first reduction assembly 2 is arranged on the side of the first motor 11 facing away from the second motor 12, and the second reduction assembly 3 is arranged on the side of the second motor 12 facing away from the first motor 11, and is symmetrically arranged with the first reduction assembly 2, so that the first motor 11, the second motor 12, the first reduction assembly 2 and the second reduction assembly 3 form a U-shaped structure.

[0029] In the embodiment of the present application, the axial direction of the first motor 11 and the second motor 12 is the Y direction, that is, the width direction of the vehicle, the length direction of the first reduction assembly 2 and the second reduction assembly 3 is the X direction, that is, the length direction of the vehicle, and the height direction of the distributed drive device is the Z direction.

[0030] The first reduction gear assembly 2 includes a first primary reduction gear group, a first secondary reduction gear group and a first output shaft 26. The first primary reduction gear group is connected to the output shaft of the first motor 11. Along the Y direction, the first secondary reduction gear group is located on the side of the first primary reduction gear group close to the first motor 11, and the first secondary reduction gear group connects the first primary reduction gear group and the first output shaft 26. The first output shaft 26 is used to connect to the external first wheel end.

[0031] The second reduction gear assembly 3 includes a second first-stage reduction gear group, a second second-stage reduction gear group and a second output shaft 36. The second first-stage reduction gear group is connected to the output shaft of the second motor 12. Along the Y direction, the second second-stage reduction gear group is located on the side of the second first-stage reduction gear group close to the second motor 12, and the second second-stage reduction gear group is connected to the second first-stage reduction gear group and the second output shaft 36. The second output shaft 36 is used to connect to the external second wheel end.

[0032] The first end cover housing 5 includes a first end cover surface 51 and a second end cover surface 52. The first end cover surface 51 is close to the first motor 11 and is located outside the first primary reduction gear set; the second end cover surface 52 is located at one end of the first end cover surface 51 away from the first motor 11 in the X direction, that is, the first end cover surface 51 and the second end cover surface 52 are arranged along the X direction. The second end cover housing 6 includes a third end cover surface 61 and a fourth end cover surface 62. The third end cover surface 61 is close to the second motor 12 and is located outside the second primary reduction gear set, and the fourth end cover surface 62 is located at one end of the third end cover surface 61 away from the second motor 12 in the X direction, that is, the third end cover surface 61 and the fourth end cover surface 62 are arranged along the X direction.

[0033] Along the Y direction, since the first and second reduction gear groups are located on the side of the first and second reduction gear groups close to the first motor 11, and the second and second reduction gear groups are located on the side of the second and first reduction gear groups close to the second motor 12, according to the structural shapes of the first reduction assembly and the second reduction assembly, the distance between the second end cover surface 52 and the fourth end cover surface 62 is set to be smaller than the distance between the first end cover surface 51 and the third end cover surface 61, so that the design of the distributed drive device is more reasonable, and the outer contour size of the distributed drive device in the top view direction is reduced, and the structure is more compact, so that when the distributed drive device is installed on the vehicle body, the distributed drive device is prevented from interfering with the longitudinal beams on both sides of the vehicle body in the width direction.

[0034] In detail, the first reduction assembly 2 includes a first gear 21, a second gear 22, a third gear 23, a fourth gear 24, a first output shaft 26 and a first intermediate shaft 27. The first output shaft 26, the first intermediate shaft 27 and the output shaft of the first motor 11 are arranged in parallel. The first gear 21 is connected to the output shaft of the first motor 11, the second gear 22 and the third gear 23 are both fixed on the first intermediate shaft 27, the first gear 21 is meshed with the second gear 22, and the first gear 21 is coplanar with the second gear 22, the fourth gear 24 is connected to the first output shaft 26, the fourth gear 24 is meshed with the third gear 23, and the fourth gear 24 is coplanar with the third gear 23, and the first output shaft 26 is used to connect to the external first wheel end, so that the power of the first motor 11 can be transmitted to the first wheel end through the first gear 21, the second gear 22, the first intermediate shaft 27, the third gear 23, the fourth gear 24 and the first output shaft 26 in sequence.

[0035] The diameter of the first gear 21 is smaller than that of the second gear 22, and the diameter of the third gear 23 is smaller than that of the fourth gear 24, so that the power of the first motor 11 is decelerated when it is transmitted to the first intermediate shaft 27 through the first gear 21 and the second gear 22, and the power is also decelerated when it is transmitted to the first output shaft 26 through the third gear 23 and the fourth gear 24, that is, the first primary reduction gear set of the first reduction assembly 2 is formed between the first gear 21 and the second gear 22, and the first secondary reduction gear set of the first reduction assembly 2 is formed between the third gear 23 and the fourth gear 24, so the first reduction assembly 2 forms a reducer with secondary reduction.

[0036] Similarly, the second reduction assembly 3 includes a fifth gear 31, a sixth gear 32, a seventh gear 33, an eighth gear 34, a second output shaft 36 and a second intermediate shaft 37. The second output shaft 36, the second intermediate shaft 37 and the output shaft of the second motor 12 are arranged in parallel. The fifth gear 31 is connected to the output shaft of the second motor 12. The sixth gear 32 and the seventh gear 33 are both fixed on the second intermediate shaft 37. The sixth gear 32 is meshed with the fifth gear 31, and the sixth gear 32 is coplanar with the fifth gear 31. The eighth gear 34 is connected to the second output shaft 36. The eighth gear 34 is meshed with the seventh gear 33, and the eighth gear 34 is coplanar with the seventh gear 33. The second output shaft 36 is used to be connected to the external second wheel end, so that the power of the second motor 12 is transmitted to the second wheel end through the fifth gear 31, the sixth gear 32, the second intermediate shaft 37, the seventh gear 33, the eighth gear 34 and the second output shaft 36 in sequence.

[0037] The diameter of the fifth gear 31 is smaller than that of the sixth gear 32, and the diameter of the seventh gear 33 is smaller than that of the eighth gear 34, so that the power of the second motor 12 is decelerated when it is transmitted to the second intermediate shaft 37 through the fifth gear 31 and the sixth gear 32, and the power is also decelerated when it is transmitted to the second output shaft 36 through the seventh gear 33 and the eighth gear 34, that is, the second first-stage reduction gear set of the second reduction assembly 3 is formed between the fifth gear 31 and the sixth gear 32, and the second second-stage reduction gear set of the second reduction assembly 3 is formed between the seventh gear 33 and the eighth gear 34, so the second reduction assembly 3 forms a reducer with two-stage reduction.

[0038] In the above, the first gear 21, the second gear 22, the third gear 23, the fourth gear 24, the first output shaft 26 and the first intermediate shaft 27 correspond one to one with the fifth gear 31, the sixth gear 32, the seventh gear 33, the eighth gear 34, the second output shaft 36 and the second intermediate shaft 37 in the Y direction, so that the first reduction assembly 2 and the second reduction assembly 3 form a symmetrical structure.

[0039] The first end cover housing 5 is fixed to the first end of the motor electronic control housing 4, and the first end cover housing 5 and the first end face of the motor electronic control housing 4 enclose a space for installing the first reduction assembly 2, that is, the first end cover housing 5 is enclosed on the outside of the first reduction assembly 2. The first end cover surface 51 is located on the outside of the first gear 21 and the second gear 22 in the Y direction, and the second end cover surface 52 is located on the outside of the fourth gear 24 in the Y direction (that is, located on the side of the fourth gear 24 away from the first motor 11). Among them, in the Y direction, since the third gear 23 and the fourth gear 24 are located on the side of the second gear 22 close to the first motor 11, if the side of the first end cover housing 5 away from the first motor 11 in the Y direction is set on the same plane, it will cause a larger gap between the second end cover surface 52 and the fourth gear 24. In the present application, the first end cover surface 51 and the second end cover surface 52 are set on different planes, and the plane where the second end cover surface 52 is located is between the plane where the first end cover surface 51 is located and the plane where the fourth gear 24 is located, thereby reducing the gap between the second end cover surface 52 and the fourth gear 24 ( Figure 1 The distance H1 in the middle is reduced, thereby reducing the outer contour size of the distributed drive device in the top view direction.

[0040] The second end cover housing 6 is fixed to the second end of the motor electronic control housing 4, and the second end cover housing 6 and the second end face of the motor electronic control housing 4 enclose a space for installing the second reduction assembly 3, that is, the second end cover housing 6 is enclosed on the outside of the second reduction assembly 3. The third end cover surface 61 is located on the outside of the fifth gear 31 and the sixth gear 32 in the Y direction, and the fourth end cover surface 62 is located on the outside of the eighth gear 34 in the Y direction (that is, located on the side of the eighth gear 34 away from the second motor 12). Among them, in the Y direction, since the seventh gear 33 and the eighth gear 34 are located on the side of the sixth gear 32 close to the second motor 12, if the side of the second end cover housing 6 away from the second motor 12 in the Y direction is set on the same plane, it will cause a larger gap between the fourth end cover surface 62 and the eighth gear 34. The present application sets the third end cover surface 61 and the fourth end cover surface 62 on different planes, and the plane where the fourth end cover surface 62 is located is between the plane where the third end cover surface 61 is located and the plane where the fourth gear 24 is located, thereby reducing the gap between the fourth end cover surface 62 and the eighth gear 34 ( Figure 1 The distance H2 in the middle) is reduced, thereby reducing the outer contour size of the distributed drive device in the top view direction.

[0041] In the above, the third gear 23 and the fourth gear 24 are arranged on the side of the second gear 22 close to the first motor 11, and the seventh gear 33 and the eighth gear 34 are arranged on the side of the sixth gear 32 close to the second motor 12, and the plane where the second end cover surface 52 is located is between the plane where the first end cover surface 51 is located and the plane where the fourth gear 24 is located, and the plane where the fourth end cover surface 62 is located is between the plane where the third end cover surface 61 is located and the plane where the fourth gear 24 is located, so that the distance between the second end cover surface 52 and the fourth end cover surface 62 is small, so as to avoid interference with the longitudinal beam on the vehicle body when the distributed drive device is installed on the vehicle body.

[0042] See also Figure 2 The first end cover surface 51 and the second end cover surface 52 form a step shape, that is, one step surface is formed at the first end cover surface 51, and the other step surface is formed at the second end cover surface 52. Along the Y direction, the distance between the second end cover surface 52 and the motor and electronic control housing 4 is smaller than the distance between the first end cover surface 51 and the motor and electronic control housing 4.

[0043] The third end cover surface 61 and the fourth end cover surface 62 form a step shape, that is, one step surface is formed at the third end cover surface 61, and the other step surface is formed at the fourth end cover surface 62. Along the Y direction, the distance between the fourth end cover surface 62 and the motor and electronic control housing 4 is smaller than the distance between the third end cover surface 61 and the motor and electronic control housing 4.

[0044] In the above, the distance between the second end cover surface 52 and the motor and electronic control housing 4 is smaller than the distance between the first end cover surface 51 and the motor and electronic control housing 4, and the distance between the fourth end cover surface 62 and the motor and electronic control housing 4 is smaller than the distance between the third end cover surface 61 and the motor and electronic control housing 4. Therefore, the distance between the second end cover surface 52 and the fourth end cover surface 62 is smaller than the distance between the first end cover surface 51 and the third end cover surface 61. When the distributed drive device is installed on a compact vehicle, since the space of the chassis of the vehicle body in the width direction is small, the distributed drive device of the present application reduces the distance between the second end cover surface 52 and the fourth end cover surface 62, so that the distributed drive device can be installed in the narrow space of the compact vehicle.

[0045] The distributed drive device also includes a first intermediate housing 71 and a first screw 81. The first intermediate housing 71 is fixed between the first end cover housing 5 and the motor electronic control housing 4.

The position of the first intermediate housing 71 for connecting with the first end cover housing 5 and the motor electronic control housing 4 is a plane, which facilitates the sealing connection between the first intermediate housing 71 and the first end cover housing 5 and between the first intermediate housing 71 and the motor electronic control housing 4.

The position of the second intermediate housing 72 for connecting with the second end cover housing 6 and the motor electronic control housing 4 is a plane, which facilitates the sealing connection between the second intermediate housing 72 and the second end cover housing 6 and between the second intermediate housing 72 and the motor electronic control housing 4.

In other words, the second end cover housing 6, the second intermediate housing 72 and the motor and electronic control housing 4 correspond to each other at the edge position, so that the second end cover housing 6 and the second intermediate housing 72 can be fixed on the motor and electronic control housing 4 at the same time by using one screw. The second screws 82 are arranged on the circumferential edge of the second end cover housing 6 , the circumferential edge of the second intermediate housing 72 and the circumferential edge of the motor and electronic control housing 4 , and therefore will not affect the installation of the second reduction assembly 3 and the second motor 12 .
