Abstract
The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces.
Claims21
A utility vehicle, comprising:
- a plurality of ground-engaging members;
- a frame supported by the ground-engaging members;
- a drivetrain supported by the frame;
- the drivetrain comprising a power source, a rear final drive, a front final drive, a rear coupling between the rear final drive and rear wheels and a front coupling between the power source and the front wheels, the drive train having a defined break point, wherein in the presence of an excessive torque on the drive train, the drive train breaks at the defined break point to permanently interrupt power being transmitted from the power source to the front wheels.

A utility vehicle, comprising:
- a plurality of ground-engaging members;
- the plurality of ground-engaging members comprising an at least one front ground-engaging member, and an at least one rear ground-engaging member;
- a frame supported by the plurality of ground-engaging members;
- a driveline supported by the frame;
- the driveline comprising a power source and a transaxle;
- the transaxle comprising a transaxle rear output, which transfers power to the at least one rear ground-engaging member, and a transaxle front output, which transfers power to the at least one front ground-engaging member;
- wherein the transaxle front output further comprises a two-piece driveshaft, the two-piece driveshaft having a generally cylindrical shape and including a first portion connected to the transaxle, a second portion connected to a front final drive, and a bearing member located between the first and second portions;
- wherein, the second portion includes a predefined rupture point.

A utility vehicle, comprising:
- a plurality of ground-engaging members;
- a frame supported by the ground-engaging members;
- a drivetrain supported by the frame;
- the drivetrain comprising a power source, a rear final drive, a front final drive, a rear coupling between the rear final drive and rear wheels, and a front coupling between the power source and the front wheels, the drive train having a defined break point in the front coupling when excessing torque is transmitted to the front coupling and the front coupling is a two-piece prop shaft and the two-piece prop shaft is defined by front and rear sections coupled together and wherein the prop shaft has a first diameter and the defined break point is defined by a shaft portion of a second diameter, where the second diameter is smaller than the first diameter.
