Abstract
A transaxle comprises first and second input shafts coaxial to each other, an output shaft drivingly connected to the second input shaft, a torque limiter interposed between the first and second input shafts, and a housing incorporating the first and second input shafts, the output shaft and the torque limiter. The torque limiter includes first and second sleeves. The first sleeve is fitted to the first input shaft unrotatably relative to the first input shaft. The second sleeve is fitted to the second input shaft unrotatably relative to the second input shaft. The first and second sleeves are layered in a radial direction of the first and second input shafts so as to be pressed against each other with a radial surface pressure to limit a torque transmitted between the first and second sleeves to a limiting value.

A transaxle comprising:
- a first input shaft;
- a second input shaft extended coaxially to the first input shaft;
- an output shaft drivingly connected to the second input shaft;
- a torque limiter interposed between the first input shaft and the second input shaft;
- and
- a housing incorporating the first and second input shafts, the output shaft and the torque limiter,
- wherein the torque limiter includes first and second sleeves,
- wherein the first sleeve is connected to the first input shaft unrotatably relative to the first input shaft,
- wherein the second sleeve is connected to the second input shaft unrotatably relative to the second input shaft, and
- wherein the torque limiter is configured such that the first and second sleeves are layered in a radial direction of the first and second input shafts and contact and press each other with a radial surface pressure therebetween to limit a torque transmitted between the first and second sleeves to a limiting value.
A transaxle comprising:
- a first input shaft;
- a second input shaft extended coaxially to the first input shaft;
- an output shaft drivingly connected to the second input shaft;
- a sleeve connected to the second input shaft unrotatably relative to the second input shaft;
- and
- a housing incorporating the first and second input shafts, the output shaft and the sleeve,
- wherein the first input shaft is fitted into the sleeve so that the first input shaft and the sleeve are layered in a radial direction of the first input shaft and contact each other with a radial surface pressure therebetween to limit a torque transmitted between the first input shaft and the sleeve to a limiting value.
A transaxle comprising:
- a first input shaft;
- a second input shaft extended coaxially to the first input shaft;
- an output shaft drivingly connected to the second input shaft;
- and
- a clutch shifter including first and second members,
- wherein the clutch shifter is shiftable between a clutch-on position and a clutch-off position,
- wherein when the clutch shifter is set at the clutch-on position, the first member is drivingly connected to the first input shaft, the second member is drivingly connected to the second input shaft, and the first and second members engage with each other by a mechanical force such as to limit a torque transmitted between the first and second members to a limiting value, and
- wherein when the clutch shifter is set at the clutch-off position, both the first and second members are drivingly isolated from one of the first and second input shafts.
