Abstract

A power interrupting apparatus is provided with: a first rotating member, a second rotating member, a clutch device adapted to interrupt a coupling between the first rotating member and the second rotating member, and an actuator adapted to actuate the clutch device. The actuator is disposed on a radially outer periphery of a part of one of the first rotating member and the second rotating member.

Claims

1. A power interrupting apparatus mounted in a power-train of a vehicle, the apparatus comprising:

a first rotating member connected to an output portion of a differential device;

a second rotating member connected to one of right and left wheels of the vehicle;

a clutch device adapted to interrupt a coupling between the first rotating member and the second rotating member;

an actuator adapted to actuate the clutch device, wherein the actuator is disposed on a radially outer periphery of a part of one of the first rotating member and the second rotating member;

a support part provided on said one of the first rotating member and the second rotating member;

a moveable body supported on the support part; and

an opposing part opposed to the moveable body in an axial direction and provided on the other of the first rotating member and the second rotating member,

wherein the clutch device is provided between the moveable body and the opposing part and adapted to interrupt the coupling between the first rotating member and the second rotating member by a movement of the moveable body,

wherein the actuator is adapted to move the moveable body in the axial direction, and

wherein the actuator is disposed on a radially outer periphery of the support part.

2. The power interrupting apparatus according to claim 1, wherein the actuator includes an actuating part configured to move the moveable body, and

wherein an inner periphery side of the actuating part is directly or indirectly supported on the radially outer periphery of the support part.

3. The power interrupting apparatus according to claim 1,

wherein the differential device is supported on a carrier and relatively rotatable with respect to the carrier, and

wherein the actuator is supported on the carrier that rotatably supports the differential device.

4. The power interrupting apparatus according to claim 3, wherein the actuator is disposed so that a bearing configured to support the differential device on the carrier is positioned between the differential device and the actuator in the axial direction.

5. The power interrupting apparatus according to claim 1, wherein the actuator and the clutch device are aligned in the axial direction.

6. The power interrupting apparatus according to claim 1, wherein the actuator and the differential device are supported on a common carrier.

7. The power interrupting apparatus according to claim 1, further comprising:

a support part provided on said one of the first rotating member and the second rotating member;

a moveable body supported on the support part; and

an opposing part opposed to the moveable body and provided on the other of the first rotating member and the second rotating member,

wherein the clutch device is provided between the moveable body and the opposing part and adapted to interrupt the coupling between the first rotating member and the second rotating member by a movement of the moveable body,

wherein the actuator includes an actuating part configured to move the moveable body,

wherein an inner periphery side of the actuating part is directly or indirectly supported on the outer periphery of the support part,

wherein the differential device is supported on a carrier and relatively rotatable with respect to the carrier,

wherein the actuator is supported on the carrier that rotatably support the differential device, and

wherein the actuator is disposed so that a bearing configured to support the differential device on the carrier is positioned between the differential device and the actuator in the axial direction.

8. The power interrupting apparatus according to claim 7, wherein the actuator is a solenoid actuator or a diaphragm actuator.

9. The power interrupting apparatus according to claim 8, wherein the clutch device comprises a dog clutch including dog teeth opposed to each other in the axial direction.

10. A power transmitting apparatus mounted in a power-train of a vehicle, the apparatus comprising:

a differential device; and

an axle disconnect device,

wherein the differential device includes;

a ring gear connected to an input side of the power-train;

a pinion shaft that integrally rotates with the ring gear;

a pinion gear supported on the pinion shaft;

a first side gear which is in mesh with the pinion gear and connected to one of right and left wheels of the vehicle; and

a second side gear which is in mesh with the pinion gear,

wherein the axle disconnect device including;

a first rotating member connected to the second side gear of the differential device;

a second rotating member connected to the other of right and left wheels;

a clutch device adapted to interrupt a coupling between the first rotating member and the second rotating member;

an actuator adapted to actuate the clutch device, and wherein the actuator is disposed on a radially outer periphery of a part of one of the first rotating member and the second rotating member;

a support part provided on said one of the first rotating member and the second rotating member;

a moveable body supported on the support part; and

an opposing part opposed to the moveable body in an axial direction and provided on the other of the first rotating member and the second rotating member,

wherein the clutch device is provided between the moveable body and the opposing part and adapted to interrupt the coupling between the first rotating member and the second rotating member by a movement of the moveable body,

wherein the actuator is adapted to move the moveable body in the axial direction, and

wherein the actuator is disposed on a radially outer periphery of the support part.
