US 2018/0154961 A1 · Variable Traction Device

Abstract

A variable traction device for drifting vehicles that allows the driver to vary the traction of the rear wheels with the road surface by alternating the weight of the drift vehicle between two sets of rear wheels with a substantially different coefficient of friction. The variable traction device includes a set of primary rear wheels, a set of secondary rear wheels, and an actuator lever. The actuator lever is located within reach of the driver and is operatively coupled to raise and lower the secondary rear wheels between a retracted position in which the vehicles weight is on the primary rear wheels and a deployed position in which the vehicles weight is on the secondary rear wheels. By manipulation of the actuator lever, it gives the driver the ability to vary the traction of the rear wheels with the road surface.

Dependent claims

A variable traction device for varying the traction of rear wheels on a drift vehicle, comprising:

(a) a rear axle pivotally mounted to a drift vehicle chassis;
(b) a pair of primary rear wheels rotatably mounted to the rear axle;
(c) a pair of spaced apart swing-arms rigidly coupled to the rear axle at a location proximate to the primary wheels;
(d) a pair of secondary rear wheels rotatably mounted to the distal end of the swing-arms, the secondary rear wheels having a substantially different coefficient of friction than the primary wheels;
and
(e) an actuator lever positioned within reach of a driver and means for operably linking the actuator lever to the rear axle,
whereby movement of the actuator lever rotates the rear axle thus raising and lowering the secondary rear wheels.
