Torque converter with stator shaft one-way clutch
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.
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.
