Abstract
Methods and system are provided for a vehicle truck assembly which includes a spring coupling an axle carrier to a truck frame. In one example, the system comprises a substantially vertically-mounted hydraulic actuator which generates hydraulic forces between the axle carrier and the truck frame. The actuator includes a cylinder, a piston, and a piston rod. Further, the actuator is coupled between the axle carrier and the truck frame with longitudinal and lateral play so that the axle carrier can move laterally and longitudinally with respect to the truck frame while the actuator applies hydraulic force.
