arrangement for a snu00f6fordon equipped with a device for improved governance

摘要

An arrangement in a snowmobile equipped with an apparatus for intensifying steering modifies the ski of the snowmobile to include a drum rotated by means of actuators, the drum forming at least part of the bearing surface of the ski. The rotation axis of the drum is oriented such that when the drum rotates, the circumferential surface of the drum moves transversely to the longitudinal axis of the ski. The drum is provided with one or more ridges protruding from its circumferential surface essentially parallel with the rotational axis of the drum. The drum is provided with one or more locking means arranged to lock the drum in a predetermined position when the apparatus for intensifying steering is not being used or to allow the drum to rotate when operation of the apparatus for intensifying steering is desired.
