Abstract: A structurally efficient vehicle suspension system capable of being isolated from the main vehicle structure by being housed within a vehicle's wheel thereby reducing risks of injury during a crash and permitting advantageous redesign of suspension geometry. By rotating the suspension link pivot axes approximately 90 degrees when compared with the positioning of traditionally known wishbone suspension systems, the upper and lower suspension links for each vehicle wheel are relocated to run essentially parallel to the axis of travel of the vehicle. Consequently, for each wheel the virtual longitudinal link length runs parallel with the axis of travel of the vehicle indicated by the arrow and virtual swing axle length runs perpendicularly to virtual longitudinal link length. However, the upper link pivot axis and the lower link pivot axis now run parallel to virtual swing axle and their convergence point defines its length.

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.

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.
