Abstract
A vehicle is disclosed. The vehicle may include an operator area including side-by-side seating. The vehicle may further include a prime mover and a transmission operatively coupled to at least one ground engaging member of the vehicle. The prime mover may be a diesel engine and the transmission may include a CVT. The prime mover and the transmission may be assembled together and supported by a frame of the vehicle through a plurality of mounts.
Claims21
A vehicle, comprising:
- a plurality of ground engaging members;
- a frame supported by the plurality of ground engaging members;
- an operator area supported by the frame, the operator area including driver controls and seating adapted to support at least two people in a side-by-side relationship;
- an assembly supported by the frame, the assembly including a prime mover operatively coupled to at least one of the plurality of ground engaging members to propel the vehicle and a transmission operatively coupled to the prime mover and the at least one of the plurality of ground engaging members to propel the vehicle, the transmission transferring power from the prime mover to the at least one of the plurality of ground engaging members to propel the vehicle, the transmission including a CVT;
- and
- a plurality of mounts coupled to the frame and supporting the assembly to isolate the assembly relative to the frame;
- and
- a damping member coupled to the assembly, the damping member being tuned to reduce the transfer of vibration from the assembly to the frame, wherein the damping member includes a damping mass which is positioned between a plurality of isolators and which is carried by a bracket.
The vehicle of 2, wherein each of the plurality of mounts includes a first portion which is directly coupled to the frame, a second portion which is directly coupled to one of the prime mover and the transmission, and a coupling member which couples the first portion to the second portion and which permits the second portion to move relative to the first portion in the direction normal to the vertical plane passing through the vehicle centerline of the vehicle.
A vehicle, comprising:
- a plurality of ground engaging members;
- a frame supported by the plurality of ground engaging members;
- an operator area supported by the frame, the operator area including driver controls and seating adapted to support at least two people in a side-by-side relationship;
- an assembly supported by the frame, the assembly including a prime mover operatively coupled to at least one of the plurality of ground engaging members to propel the vehicle and a transmission operatively coupled to the prime mover and the at least one of the plurality of ground engaging members to propel the vehicle, the transmission transferring power from the prime mover to the at least of the plurality of ground engaging members to propel the vehicle, the transmission including a CVT;
- a plurality of mounts coupled to the frame and supporting the assembly to isolate the assembly relative to the frame;
- a rear drive unit positioned rearward of the operator area and coupled to a first ground engaging member and a second ground engaging member both positioned rearward of the operator area;
- a rear drive shaft operatively coupling the rear drive and the CVT, the CVT providing power to the rear drive;
- wherein at least a third mount and a fourth mount are directly coupled to the transmission and are coupled to the frame at respective positions outboard of the rear drive shaft;
- a front drive unit positioned forward of the operator area and coupled to a third ground engaging member and a fourth ground engaging member both positioned forward of the operator area;
- and
- a front drive shaft operatively coupling the front drive and the CVT, the CVT providing power to the front drive, wherein at least a first mount and a second mount are directly coupled to the prime mover and are coupled to the frame at respective positions outboard of the front drive shaft.
