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.

A steering control system for snow vehicles, being of the type of steering control system suitable for equipping vehicles specialized in snow travel, of the snowmobile type, or more specifically, of the stand-up snowmobile type (1), which start from a basic configuration of at 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 the right and left of the longitudinal axis of the snowmobile (1) and coupled by one of their ends to the chassis (2) of the snowmobile (1), which by means of a pivot bolt (14a, 14b) at said end can tilt with an ascending and descending movement with respect to the horizontal surface plane;
- a pair of ski spindles (6a, 6b) equipped with cams (9a, 9b), with the spindles arranged longitudinally to the direction of travel and capable of radially rotating (27c) while coupled at the 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 snowmobile (1) and connected to a pull cable or drive shaft (16a,16b). The pedals coupled to the chassis (2) of the snowmobile (1) by means of at least one pivot bolt (17a, 17b) on which it can swing;
- a pair of independent tie rods (8a, 8b), connected at one end to a section of the snowmobile (1) chassis (10a, 10b) and at the opposite end to a cam (9a, 9b) located on each ski spindle (6a, 6b);
- a pair of springs (42) or compression springs (13a, 13b) allowing locking and return rotation of the respective swingarms (5a, 5b);
- and
- a set of pull cables (12a, 12b) or drive shafts, routed over guide rollers (11a, 11b) or rockers which transmit pedal movement (7a, 7b) to the swingarm (5a, 5b).
