Patent ID: 8056656

Claim:
An anti-torque device for use in cooperation with a traction assembly for use on a vehicle, the vehicle having a frame, the traction assembly comprising a frame structure, a sprocket wheel, at least one additional wheel pivotally mounted on the frame structure, and a longitudinally extending traction band disposed around the sprocket wheel, the frame structure and the at least one additional wheel, the anti-torque device comprising: a) a first elongated member comprising a first end and a second end, the first end being configured for pivotal attachment, the first elongated member comprising a first abutment structure; b) a second elongated member comprising a third end and a fourth end, the second member being slidingly coupled to the first member such that the third end is substantially located between the first end and the second end, the fourth end being configured for pivotal attachment, the second member comprising a second abutment structure located between the third end and the second end, and a third abutment structure located between the fourth end and the second end; c) a first resilient element located between the first abutment structure and the second abutment structure; d) a second resilient element located between the first abutment structure and the third abutment structure; wherein extension of the anti-torque device is substantially resiliently countered by the first resilient element and wherein compression of the anti-torque device is substantially resiliently countered by said the second resilient element.
