Abstract: A motor suspension assembly includes a frame bracket configured to be coupled with a vehicle frame having mounting locations for upper and lower suspension bars that are positioned for a direct current (DC) traction motor to rest upon the upper suspension bar and for elastic pads to be disposed between the upper and lower suspension bars. The frame bracket is configured to be coupled with the vehicle frame in place of at least one of the upper suspension bar or the lower suspension bar. The assembly also includes a dog bone suspension link configured to be coupled with a nose bracket of an alternating current (AC) traction motor and the frame bracket. The dog bone suspension link is configured to absorb vibration by at least partially rotating about one or more of the nose bracket or the frame bracket during operation of the AC traction motor.

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.

Abstract: Truck assemblies, systems and methods are provided for transferring weight supported by various wheels, and axles. An example truck assembly may include a truck frame element, and a carrier coupled with the truck frame element. A bias may be configured to bias the carrier away from the truck frame element. An actuatable linkage arrangement may include a compliant linkage coupled with the carrier. The compliant linkage may pull the carrier against the bias in a first direction.

Abstract: Truck assemblies, systems and methods are provided for transferring weight supported by various wheels, and axles. The vehicle suspension method includes operating the suspension in a first mode with a first effective suspension spring rate; and operating the suspension in a second mode with a second, different, effective suspension spring rate.
