A coaxial co-located vehicle power drive and steering system includes a motor coupled to a transmission having a drive shaft with a first portion and a second portion mechanically interlocked by a spline having corresponding meshing features extending parallel to the drive shaft longitudinal axis. A drive shaft housing enclosing at least a length of the drive shaft, the drive shaft housing including a first portion and a second portion mechanically interlocked by a spline having corresponding meshing features extending parallel to the drive shaft longitudinal axis. A distal end of the drive shaft terminating within a differential gearbox in mechanical communication with an axle. A steering system coupled to the drive shaft housing second portion, the steering system including one or more rotatable gears which cause an angular rotation of the housing in relation to the drive shaft.

Provided herein are a suspension apparatus and a specialized vehicle including the same. The suspension apparatus includes a crankshaft fixed to a vehicle body, a housing rotatably connected to the crankshaft, a first damping portion arranged in the housing and having a damping fluid accommodated in the first damping portion, an amount of the damping fluid in the first damping portion being adjusted according to an external force applied to the vehicle body, a second damping portion arranged in the housing, connected to the first damping portion such that the damping fluid moves between the first damping portion and the second damping portion, and including: a first space accommodating a compressed gas; and a second space accommodating the damping fluid, the first space facing the second space; and a rotational force applier arranged in the housing and configured to apply a rotational force to the housing by adjusting an amount of a working fluid in the rotational force applier.

A work vehicle may include a load sensor, an engine, a drive train driven by the engine and a track system including at least one track. The track system is connected to the drive train. The work vehicle may further comprise a temperature sensor configured to sense a temperature and a vehicle control system configured to receive the sensed temperature and a vehicle load from the load sensor. The vehicle control system is configured to output a work speed vehicle alert based upon a combination of the temperature sensed by the temperature sensor and the vehicle load sensed by the load sensor.

A track system for traction of a vehicle that is connectable to an axle of the vehicle and includes a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track-engaging assembly includes a drive wheel for driving the track, idler wheels for contacting a bottom run of the track, and a bogie carrying the idler wheels. The track system includes a transmission for transmitting power from the axle of the vehicle to the drive wheel such that a rotational speed of the drive wheel is different from a rotational speed of the axle of the vehicle. The track system includes a connector disposed between the transmission and the bogie such that the bogie is movable (e.g., pivotable) relative to the transmission. The connector may be disposed below an output shaft of the transmission.

A track system for a vehicle having at least three axles is disclosed. The track system includes a frame to which sprocket, idler and support wheel assemblies are connectable, an endless track and a pivoting assembly. The pivoting assembly has a casing connectable to a second axle and at least one pivotable member that has first and second portions respectively pivotally connected to the casing and to the frame. The at least one pivotable member is pivotable between first and second positions about a longitudinally extending pivot, in response to which the first portion is displaced laterally relative to the second portion, and pivotable between third and fourth positions about a lateral pivot axis in response to which the first portion is displaced longitudinally relative to the second portion. A pivoting assembly, a pivoting assembly including a resilient assembly, and a vehicle having the track system are also disclosed.

A robot R includes a pair of crawler devices 2 supported by a body 1. Each of the crawler devices 2 includes a crawler unit 3 supported by the body 1 such that the crawler unit 3 is rotatable about a first rotational axis L. The crawler unit 3 includes a support 10 extending along the first rotational axis L1 and a pair of crawler parts 20A, 20B mounted on the support 10. Each of the crawler device 2 includes a rolling driving member 46 connected to the support 10 of the crawler unit 3, a rolling motor 60 that rotationally drives the rolling driving member 46, a crawler drive shaft 41 extending along the first rotational axis L1 through a gap between the pair of crawler parts 20A, 20B, a crawler motor 50 that rotationally drives the crawler drive shaft 41 and a torque transmitting mechanism 42 that transmits rotary torque of the crawler drive shaft 41 to the pair of crawler parts 20A, 20B, The crawler motor 50, as well as the rolling motor 60, is disposed outside of the crawler unit 3.
