Abstract
Traction systems for snowmobile skis producing traction on snow and ice covered surfaces; consisting a pair of snowmobile skis each having an assembly of parts; driven by an hydraulic rotor that pivots the skis, adjusting their position when cornering, providing traction, according to a snowmobile steering system . And is powered and controlled by at least one of: hydraulic steering system, an electro-hydraulic steering system; an electric power steering system using an electric motor instead of hydraulic rotor.
Claims5
A System for producing traction on snow and ice covered surfaces for use with skis;
- said system comprising:
- each of a pair of traction apparatus, are adapted to each of a pair of snowmobile skis;
- each apparatus consisting of an hydraulic double-vane rotary actuator, that engages with a drive shaft that enters pillow block bearings held together by a cover that engages a snowmobile connecting member;
- said drive shaft exits and enters a third pillow block bearing fix to a snowmobile ski, and ends engaged in a drive shaft support block;
- said third pillow block bearing with the drive shaft support block are both fixed to the said snowmobile ski;
- a hydraulic power steering system of a snowmobile controls each traction apparatus by supplying hydraulic oil pressure to each double-vane rotary actuator of each traction apparatus;
- the said hydraulic double-vane rotary actuator pivots;
- each drive shaft, with each apparatus mounted to each of a pair of snowmobile skis;
- together all move simultaneously clockwise or counterclockwise.
