摘要： A vehicle suspension system comprising a frame and a pair of levers carried by the frame. Each lever is pivotally mounted for swinging movement on an axis extending transverse to the frame. A pair of forward-extending beams and rearward-extending beams have pivot connections with a respective lever and support a forward and rearward axle. Two forward springs and two rearward springs are each interposed between the beams and the frame. A pair of torque arms is carried by the frame forward of the forward-extending beams. Each torque arm has a first pivot connection with a respective beam and a second pivot connection with the frame forward of the first pivot connection with the beam. The torque arms function to restrict pivotal movement of the beams about their respective pivot connections with the levers thereby to reduce torsional forces applied to the forward axle.

摘要： Landing gear for selectively supporting a semitrailer and a method of assembly of the landing gear is provided. The landing gear includes a leg having an upper section and a lower section telescopingly received in the upper section. A lead screw extends and retracts the upper and lower sections relative to each other upon rotation thereof. An input shaft applies a torque to the lead screw to drive rotation thereof, the input shaft being rotatable about a rotation axis and movable in translation along the rotation axis for shifting between a first position for low gear operation and a second position for high gear operation. An output shaft, axially aligned with the input shaft, has an output gear for transmitting torque to the lead screw. A gearing subassembly is received in the upper leg section and is configured to augment lift when the input shaft is in the first position and augment speed in the second position.
