Systems and methods provide a torsion bar assembly coupled to one or more casters of a material handling vehicle (MHV). The torsion bar assembly is configured to maintain contact between a travel surface of the MHV (e.g., ground) and a drive wheel of the material handling vehicle throughout the service life of the drive wheel.

A driving robot device is provided. The driving robot device may include a plurality of suspensions configured to absorb a shock applied by a driving surface on which the driving robot device drives; a first driving part that includes a motor and is configured to adjust a strength of the plurality of suspensions; and at least one processor configured to control the first driving part to adjust the strength of the plurality of suspensions based on driving surface information with respect to a state of driving surface, and based on food information with respect to a state of food carried by the driving robot device.

A toe correction bushing including: an inner cylinder; a tubular damping mechanism which surrounds the inner cylinder; a retaining cylinder which surrounds the damping mechanism; an outer cylinder which surrounds the retaining cylinder; and an outer elastic body which connects the outer cylinder and the retaining cylinder. The retaining cylinder includes a bottom plate portion which extends inward in a radial direction from an end portion of the retaining cylinder on one side of an axial direction and a crimped portion which is located at an end portion on the other side of the axial direction and is crimped on the inside of the radial direction. The outer cylinder includes a facing surface which faces the one side of the axial direction and faces a part of a vehicle body. The facing surface is provided with a cushioning elastic body.

A chassis component (16), with a first end section (17) and a second end section (18) and a connecting section (19) is arranged between the two end sections (17, 18). At least one ball joint (21) is associated with one of the two end sections (17, 18), and a sensor device (22) is associated with the ball joint (21). A first sensor element (23) of the sensor device (22) is arranged on the end section (18) that has the ball joint (21) and a second sensor element (24) is arranged on an inner joint component (25) of the ball joint (21). In order to avoid damage to the chassis component (16) and/or a disturbance-inducing factor for the sensor device (22) caused by a tensile or compressive load, the connecting section (19) has an elastically deformable zone (20) preferably in the longitudinal and/or the transverse direction of the vehicle.

A twist axle assembly (20) of a vehicle includes a pair of trailing arms (22) and a twist beam (24) having a base portion (46) extending along an axis (A) between first and second twist beam ends (42, 44). The twist beam (24) includes a pair of side walls (48) extending downwardly from the base portion (46) and each disposed in spaced relationship with the trailing arms (22). At least one mounting bracket (54) extends from a first mounting bracket end (56) disposed in abutting relationship with a respective trailing arm (22) to a second mounting bracket end (58) disposed in overlaying relationship the side walls (48) of the twist beam (24) for allowing the mounting bracket to axially slip or slide along the side walls (48) of the twist beam (24) and provide for lateral or axial adjustment of the twist axle assembly (20) during the manufacturing process.

A vehicle suspension system having a twist beam axle including a crossbeam and two trailing arms connected thereto. The rear ends of each trailing arm, in the motor vehicle longitudinal direction, having with a wheel mount for fastening a motor vehicle wheel. The front ends of each trailing arm connected via a bearing to the motor vehicle body. Each bearing associated with a MEMS designed as an actuator wherein movements of the bearings and therefore the twist beam axle about the vertical motor vehicle axis can be caused or unfavorable movements of the twist beam axle can be counteracted.
