The invention provides an axle for wheels of a two-track motor vehicle. The axle has, on each vehicle side, a wheel carrier, a damper strut, a transverse link and a transverse leaf spring which controls the wheel at least partially laterally and/or in the vehicle longitudinal direction. The damper strut has a damper tube and a damper piston which can be moved in the damper tube along a damper longitudinal axis. The damper strut is attached by the damper tube to the wheel carrier. The transverse link is attached by a wheel-carrier-side end region to the wheel carrier. The transverse leaf spring extends substantially in the vehicle transverse direction and has at least one wheel-carrier-side end region. The transverse leaf spring is attached by the wheel-carrier-side end region thereof to the damper strut and is supported on the damper strut.

An electric vehicle, an automatic driving method and equipment, and an automatic freight transportation method and system, the electric vehicle (1) comprising a plurality of sets of wheel assemblies (2) disposed at the lower surface of a chassis (10), wherein the plurality of sets of wheel assemblies (2) are independent of each other; each wheel assembly (2) comprises a wheel (21), a driving device (22) and a displacement device (23); the driving devices (22) drives the wheels (21) to rotate, and the displacement devices (23) at least drives the wheels (21) to move along the vehicle body width direction (X) of the electric vehicle (1). Each set of wheel assemblies (2) of the electric vehicle (1) has an independent power system, and the wheels (21) of each of the wheel assemblies (2) are independently controlled by means of the driving devices (22) and the displacement devices (23), so that when used to carry people, the electric vehicle (1) may meet the driving requirements of being highly flexible, stable, safe and comfortable; and when used for loading goods, the electric vehicle (1) may meet the cargo transportation requirements of being fully automated, highly efficient, highly accurate, low cost and highly safe.

In a turning system for a vehicle, a toe angle change is acquired based on an estimated stroke which is a stroke of a suspension which is estimated based on a moving state of a vehicle and an actual stroke which is an actual stroke of the suspension detected by a stroke sensor, and control of a turning angle of a vehicle wheel is performed based on the acquired toe angle change. Accordingly, it is possible to appropriately perform control of a turning angle even in travel.

A front suspension lift kit for a golf cart includes first and second beams mountable to a frame of the golf cart. A first strut is mountable to the frame of the golf cart and a distal end portion of the first beam such that the first strut extends between the frame of the golf cart and the first beam. A second strut is mountable to the frame of the golf cart and a distal portion of the second beam such that the second strut extends between the frame of the golf cart and the second beam. A support bracket is mountable to the first and second beams at the distal end portions of the first and second beams. The lift kit also includes a swing arm, a spindle bracket, and a coil-over shock.

A suspension joining structure may include a lower arm which has one end portion fastened to a vehicle body, an assist knuckle on which a strut portion is located, a fastening unit which is configured so that a second end portion of the lower arm and a lower end portion of the assist knuckle are fastened, a revoknuckle which is pivotally fastened to the assist knuckle to be rotated independently of the assist knuckle to perform the steering of a wheel, and a steering input portion fastened to the revoknuckle and configured to apply a steering force to the revoknuckle upon the steering of the wheel.

A suspension joining structure includes: a lower arm having one end fastened to a vehicle body; an assist knuckle having a strut thereon; a fastening unit configured to connect one end of the lower arm and a lower end of the assist knuckle to each other; a suspension fastened to the assist knuckle and rotating independently of the assist knuckle for steering of a wheel; a steering input part connected to the assiste knuckle, and configured such that a steering force is applied to the suspension upon steering; and a rotation transfer unit arranged between the suspension and the steering input part.

The present application discloses a steering control system, a method and a crane. The steering control system includes: one or more first angle sensors, one or more second angle sensors, and a steering controller; each of the first angle sensors collects an actual steering angle of a wheel corresponding to a mechanical steering axle as a first steering angle; each of the second angle sensors an actual steering angle of a wheel corresponding to an electrically controlled steering axle as a second steering angle; the steering controller obtains a theoretical steering angle of the wheel corresponding to the electrically controlled steering axle in a corresponding travel mode according to the first steering angle, and compares the second steering angle with the theoretical steering angle, to control the wheel corresponding to the electrically controlled steering axle to steer according to a difference therebetween.

A suspension damping device installed at a chassis of a mobile robot comprises a vehicle frame, a controlling arm set and a damping device. The vehicle frame is fixed to the chassis and arranged on the ground. One end of the controlling arm set is hinged to the vehicle frame, and the other end of the controlling arm set is hinged to a steering device, so the controlling arm set controls the motion stability of the steering device. One end of the damping device opposite to the ground is hinged to the vehicle frame, and the other end of the damping device faced to the ground is hinged to the steering device. A six-wheeled bionic chassis which comprises a chassis frame, a controller, a sensor, front wheel suspension assemblies, middle wheel suspension assemblies and rear wheel suspension assemblies is also disclosed in the present invention.
