A mobile platform for materials transport is provided. The platform includes a pair of suspension devices that in turn include a pair of rocker beams which can be rotated between two positions: a first position where central wheels attached thereto can be used to drive the platform; and a second position where the central wheels are retracted and the platform can be rolled on end wheels without the friction of the central wheels, and an associated drive system, impeding movement of the platform. Furthermore, data from sensors and/or load cells can be used to control movement of the platform; specifically, shifts in load distribution and/or sensed forces at the suspension devices can indicate that a load (and/or materials) has shifted and/or is shifting and movement of the platform is adjusted accordingly, for example to prevent the platform and/or the load (and/or materials) from tipping.

A leaning vehicle has a frame; a shock tower pivotally connected to the frame; front left and right ground engaging members; front left and right suspension assemblies; portions of the front left suspension assembly, the front left ground engaging member and other components of the vehicle suspended by the front left suspension assembly have a first unsprung mass; portions of the front right suspension assembly, the front right ground engaging member and other components of the vehicle suspended by the front right suspension assembly have a second unsprung mass; a moment of inertia of the shock tower being at least twenty-five percent of a combined moment of inertia of the first and second unsprung masses; a steering assembly; a rear suspension assembly; at least one rear ground engaging; and a motor.

The present application discloses an air suspension system, including a frame for mounting a vehicle body, a bridge housing for mounting wheels, and air springs, shock absorbers, a connecting rod frame and a thrust module connected between the frame and the bridge housing. Since the thrust module is standardized, a suitable thrust module can be matched according to different working conditions, thereby making the complex suspension adjustment work lightweight.

Tandem axle assemblies and associated systems and components are provided for use on heavy duty trucks, trailers, and/or other vehicles. Tandem axle assemblies may include a drive axle and a non-drive lift axle mounted to a non-torque reactive suspension system having hanger brackets positioned between the tandem axles. Roll stability components of the suspension system can be located on the drive axle side of the suspension, reducing weight, cost, and complexity of the tandem axle assembly. The non-drive lift axle can be operated by a control system during vehicle dynamic operation to improve traction performance of the vehicle.

A robot apparatus may include a main body, a main hinge positioned at a lower part of the main body, a main link member having a center part coupled to the main hinge and configured to pivot about the center part, a plurality of sub-link members coupled at both sides of the main link member, and a first wheel and a second wheel connected to each of the plurality of sub-link members. Each of the plurality of sub-link members is connected to a first hinge member and a second hinge member at positions spaced apart from the main link member at the lower part of the main body, and is configured to pivot about the first hinge member and the second hinge member according to movements of the first wheel and the second wheel.
