Abstract
A dual torque limiter on a utility vehicle having a gear train connected to a main shaft through a first slip clutch assembly that releases the gear train from the main shaft if torque exceeds a predetermined limit. The main shaft is connected to a rear drive train. The front drive train is connected to the main shaft through a second slip clutch assembly that releases the front drive train from the main shaft if torque exceeds a predetermined limit.
Claims16
A dual torque limiter on a utility vehicle, comprising:
- a main shaft rotatably mounted between a front drive train and a rear drive train in the utility vehicle;
- a front slip clutch assembly releasably securing the main shaft to the front drive train through a releasable engagement device between the front slip clutch assembly and the main shaft;
- a rear slip clutch assembly releasably securing a rear drive gear to the main shaft through a releasable engagement device between the rear slip clutch assembly and the rear drive gear;
- wherein each of the front slip clutch assembly and the rear slip clutch assembly independently release the main shaft from the front drive train and the rear drive gear respectively if torque through the corresponding drive train exceeds a predetermined torque.
A dual torque limiter of a utility vehicle, comprising:
- a front drive train connected to a front slip clutch assembly with a plurality of friction discs attached thereto;
- a rear drive train connected to a rear slip clutch assembly with a plurality of friction discs attached thereto;
- a main shaft inserted through the front slip clutch assembly and through the rear slip clutch assembly, the main shaft having a plurality of releasable engagement devices attached thereto;
- and
- pair of springs urging the outer and the inner friction discs into engagement;
- the springs allowing disengagement of the releasable engagement devices at a predetermined torque limit.
