Vehicle starting device

1. A starting device for a vehicle comprising:

a spring support ring; and,

a coiled clutch comprising:

a first end frictionally engaged with the spring support ring;

a center portion connected to the first end and arranged for compressive engagement with an outer shell of a torque converter; and,

a second end connected to the center portion and arranged for rotational displacement in a first direction relative to the first end to compressively engage the center portion with the outer shell.

2. The starting device of claim 1 wherein the spring support ring encircles the coiled clutch.

3. The starting device of claim 2 wherein the spring support ring includes a circumferential groove for receiving the first end.

4. The starting device of claim 3 wherein a free diameter of the first end is greater than a free diameter of the center portion.

5. The starting device of claim 2 wherein the spring support ring is integral with a transmission bellhousing for the vehicle.

6. The starting device of claim 2 wherein the spring support ring is press fitted into a transmission bellhousing for the vehicle.

7. The starting device of claim 2 further comprising a centering plate arranged for fixing between an engine and a transmission, wherein the spring support ring is fixed to the centering plate.

8. The starting device of claim 2 further comprising:

a centering plate fixed to the spring support ring; and,

a gear support plate drivingly engaged with the clutch second end and rotatably connected to the centering plate.

9. The starting device of claim 8 further comprising a ring gear fixed to the gear support plate.

10. The starting device of claim 1 further comprising a return clutch drivingly engaged with the second end of the coiled clutch and arranged to displace the second end in a second direction, opposite the first direction, relative to the first end, to release the clutch center portion from the shell.

11. The starting device of claim 10 wherein the return clutch comprises a coiled return spring and a friction clutch.

12. The starting device of claim 11 wherein the friction clutch comprises:

a load tube circumscribing the return spring;

at least one friction washer; and,

a resilient element urging the load tube against the friction washer.

13. The starting device of claim 10 wherein the return clutch is drivingly engaged with a starter motor for the vehicle.

14. A starting device for a vehicle comprising:

a centering plate;

a spring support ring fixed to the centering plate;

a gear support plate rotatable relative to the centering plate and arranged for fixing to a torque converter;

a ring gear fixed to the ring support plate; and,

a wrap spring clutch including:

a first end frictionally engaged with the spring support ring;

a second end fixed to the gear support plate; and,

a center portion arranged for compressive engagement with the torque converter.

15. The starting device of claim 14 wherein the spring support ring is fixedly attached to an engine or a transmission of the vehicle.

16. The starting device of claim 14 further comprising a starter motor fixed to the spring support ring and including a gear drivingly engaged with the ring gear.

17. The starting device of claim 16 further comprising a return clutch including:

a housing;

a drive hub arranged for driving connection with the starter motor;

a load tube frictionally engaged with the housing; and,

a torsion spring with a first end connected to the drive hub and a second end connected to the load tube.
