Abstract
A front suspension for a tractor has an axle that is pivotally coupled to an axle carrier to pivot about a substantially longitudinal axis. The axle carrier, in turn, is pivotally coupled to the chassis of the vehicle to pivot about a generally vertical axis. The front end of the axle carrier is supported by a counter frame that prevents the axle carrier from twisting about a longitudinal axis. The counter frame is pivotally coupled to the chassis of the tractor to pivot about a generally lateral and horizontal axis. Both the axle carrier and the counter frame are constrained to pivot about the common horizontal and lateral axis with respect to the chassis of the tractor. Springs are coupled between the counter frame and the chassis of the tractor to control the pivoting of the counter frame with respect to the tractor and provide shock absorbing for the front suspension.
