Abstract
Steering control system for snow vehicles, suitable for equipping vehicles like snowmobile type or more specifically of the standing snowmobile style (1), with a basic configuration of, at least, two front skis (4a, 4b) and one drive track (3). The system acts on one or the other ski independently, and depending of the chosen path left or right, the rider can activate the left ski system or the right ski system using a mechanism that can be manual or assisted. This swing arms system (5a, 5b) and rotating ski spindle (6a, 6b) allow an easy and stable lateral tilt of the snowmobile, and besides generate a multiple and simultaneous orientation on the ski (4a) or (4b). All these factors gives the snowmobile high maneuverability and efficient control of the trajectory.
Claims13
A steering control system for a snow vehicle having least two front skis (4a, 4b) and one rear track (3), characterized in that the system comprises:
- a pair of independent swingarms (5a, 5b), located to a right and left of the longitudinal axis of the snow vehicle (1) and coupled by one of their ends to a chassis (2) of the snow vehicle (1), which by means of a pivot bolt (14a, 14b) at said end can tilt with an ascending and descending movement with respect to a horizontal surface plane;
- a pair of ski spindles (6a, 6b) equipped with cams (9a, 9b), with the spindles arranged longitudinally to a direction of travel and capable of radially rotating (27c) while coupled at an opposite end (15a, 15b) of the swingarms (5a, 5b);
- a pair of independent rocker foot pedals (7a, 7b) located to the right and left of the longitudinal axis of the snow vehicle (1) and connected to a set of pull cables or drive shafts (12a,12b), the pedals coupled to the chassis (2) of the snow vehicle (1) by means of at least one pivot bolt (17a, 17b) on which the pedals can swing;
- a pair of independent tie rods (8a, 8b), connected at one end to a section of the snow vehicle (1) chassis (10a, 10b) and at an opposite end to the respective cam (9a, 9b) located on each ski spindle (6a, 6b);
- and
- a pair of return members (42, or 13a,13b) allowing locking and return rotation of the respective swingarms (5a, 5b);
- wherein the set of pull cables (12a, 12b) or drive shafts are routed over guide rollers (11a, 11b) or rockers which transmit pedal movement (7a, 7b) to the respective swingarms (5a, 5b).
