Off-road vehicle and suspension for such vehicle

An off-road vehicle of the type including a chassis and an engine connected to the chassis for propelling the vehicle, the vehicle comprising:

• at least two tracks for supporting the vehicle on a surface,
• the at least two tracks comprising a first track adjacent a first lateral edge of the chassis and a second track opposite to the first track and adjacent a second lateral edge of the chassis opposite to the first lateral edge,
• wherein the first track and the second track are each part of a separate first track assembly and second track assembly,
• each of the separate first and second track assemblies comprising:
• a subframe with multiple wheels positioned around a circumference thereof to guide the corresponding track,
• a first axle and a second axle that extend from the subframe to the chassis for connecting the subframe to the chassis,
• each subframe being hingeably connected to the chassis at the first axle,
• a suspension system which moveably connects each subframe to the chassis at the second axle to allow a vertical movement of the subframe with respect to the chassis, the suspension system comprising a Watt's linkage,
• the first track assembly has a first Watt's linkage and the second track assembly has a separate second Watt's linkage,
• wherein the first Watt's linkage of the first track assembly is operatively connected to a first damper to restrict vertical movement of the subframe of the first track assembly with respect to the chassis, and
• wherein the second Watt's linkage of the second track assembly is operatively connected to a second damper to restrict the vertical movement of the subframe of the second track assembly with respect to the chassis.

A track assembly for connection to an off-road vehicle, the track assembly comprising:

• a track and
• a subframe with multiple wheels positioned around a circumference thereof to guide the track, the subframe having two sites for operative connection to a chassis, the two sites including:
• a downstream site where the subframe is hingeably connectable to the chassis, and
• an upstream site comprising a Watt's linkage having a middle bar and two opposing end bars hingeably connected thereto, the middle bar being rigidly connected to the subframe and the two opposing end bars each having a connection at respective distal ends thereof for connecting the Watt's linkage to the chassis of the off-road vehicle.
