摘要： A personal traction transportation vehicle which includes two pulley-motor-wheels which drive a connected chassis forward. The chassis is stabilized by a connection to a drag pole which is controlled by the operator. The vehicle is electrically driven by a removable battery pack. At least one drag pole of the two simulated ski poles is attached to the chassis through joints in a manner allowing the handles of the ski poles to be free to move in the plane normal to the direction of forward movement. The other drag pole can be connected through a universal joint. The vehicle is steered by differentially pulling on the drag poles. The user is not restricted in the typical operating range of vertical movement the stabilizing pole, since the chassis is able to rotate within broad constraints about the axis of the drive wheels. The linkage between the stabilizing pole and the chassis allows for freedom of movement only laterally on a horizontal axis via a "forked" link: the forked link provides a means of stabilizing the chassis by creating a vertically rigid link between the drag pole and the chassis. Notwithstanding the evident restriction on movement of one of the drag poles (due to ballast and torque due to acceleration and deceleration), the lateral movement of either drag pole relative to its point of contact with the drive assembly does not affect steering, and the countertorque required to maintain chassis stability is minimal.
