Abstract

A hydraulic torque converter including a stator, a stator shaft, a one-way clutch including blocking elements and being connected to the stator shaft, a stator hub connecting the stator to the one-way clutch, and axial bearings supporting the stator hub, an axial length of the blocking elements being larger than an axial length between the bearings. Embodiments with blocking elements in a pump hub with an inner race with a radius similar to the stator shaft and with adjacent blocking elements are also disclosed.

Claims (20)

1. A hydraulic torque converter comprising:

a stator;

a stator shaft;

a one-way clutch including blocking elements and being connected to the stator shaft;

a stator hub connecting the stator to the one-way clutch; and

axial bearings supporting the stator hub;

an axial length of the blocking elements being larger than an axial length between the bearings, the blocking elements being strips.

2. The hydraulic torque converter as recited in claim 1 wherein the blocking elements are located radially inside the axial bearings.

3. The hydraulic torque converter as recited in claim 1 wherein the one-way clutch includes an inner race having a similar radius to the stator shaft.

4. The hydraulic torque converter as recited in claim 1 wherein the one-way clutch includes a clutch housing radially outside the blocking elements.

5. The hydraulic torque converter as recited in claim 1 wherein the one-way clutch has a clutch housing having an inner radius and an inner race having an outer radius, the distance between the inner radius and the outer radius being less than a width of the strips.

6. The hydraulic torque converter as recited in claim 1 further comprising a housing including a pump hub surrounding the stator shaft and at least partially surrounding the blocking elements.

7. The hydraulic torque converter as recited in claim 1 further comprising a housing, the stator shaft extending beyond the housing and wherein one-way clutch has an inner race supporting the blocking elements and having a radius similar to a radius of the stator shaft outside of the housing.

8. A hydraulic torque converter comprising:

a housing having a pump hub;

a stator;

a stator shaft located partially within the pump hub;

a one-way clutch including blocking elements and being connected to the stator shaft; and

a stator hub connecting the stator to the one-way clutch;

the blocking elements being located at least partially inside the pump hub.
