An output end of the steering motor is provided with a first input gear. An end of the main shaft drives a first rear wheel to rotate by a two-stage gear transmission system and a first rear-wheel motion conversion mechanism, and the other end of the main shaft drives a second rear wheel to rotate by the planetary gear coupling mechanism and a second rear-wheel motion conversion mechanism. The intermediate gear, the transmission gear and a sun gear of the planetary gear coupling mechanism are provided on the main shaft. The intermediate gear meshes with the first input gear.

A steering actuator comprising a shaft having an input coaxial with an output, wherein the output is in drivable communication with one or more wheels of a vehicle, and a locking mechanism configured to enable the shaft to rotate in both a first direction and a second direction in response to torque provided at the input, and prevent the shaft from rotating in both the first direction and the second direction in response to torque provided at the output.

Methods, apparatus, systems and articles of manufacture are disclosed to perform a tank turn. An example vehicle includes a first wheel and a second wheel, the first wheel located on an end of a first axle, the second wheel located on an end of a second axle, the end of the first axle opposite to the end of the second axle, a first suspension coupled to the first wheel, a second suspension coupled to the second wheel, and a controller to drive the first axle in a first direction, drive the second axle in a second direction, the first direction different from the second direction, and decrease a first suspension load of the first suspension and a second suspension load of the second suspension.

A suspension and drive mechanism for a steerable wheel of a vehicle, comprising a wheel support assembly supporting the wheel having a rolling axis and a wheel width defined by inner and outer wheel edges. Front and rear upper control arms coupled between a chassis and the wheel support assembly, and front and rear lower control arms between the chassis and the wheel support assembly. The front and rear upper control arms being coupled to the wheel support assembly above the rolling axis and inboard of the wheel inner edge, and front and rear lower control arms being coupled to the wheel support assembly below the rolling axis and inboard of the wheel inner edge. The control arms are angled so as to establish a virtual steering pivot axis for the wheel support assembly, the virtual steering pivot axis extending transverse of the rolling axis and located within the width of the wheel. The virtual steering pivot axis location varies according to a steering angle of the wheel support assembly as controlled by the steering arm.
