ABSTRACT:
An improved connection between the two steering posts and the steering skis at the forward end of a snowmobile which includes for each post and each ski a downwardly convexed leaf spring connected at its front and rear ends to the ski and bracket structure that connects the intermediate portion of the spring to the post. The bracket structure includes a pair of brackets, one of which is connected to a forward portion of the spring and the other of which is connected to a rearward portion of the spring so as to have a relatively long length of spring between the two portions. The two brackets have vertical walls that are disposed side-by-side and extend upwardly to be connected to a horizontal trunnion mounted or fixed to the lower end of the post.
