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.

A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which is selectively releasable in order to provide a steering angle which is different than the first steering axle. The components for connecting the axle limb to the support structure form a McPherson suspension.

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 assist 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.

In a riding mower having a frame, a mower deck supported beneath the frame, a chair on said frame and a source of motive power also supported on said frame and including two hydraulic transaxles depending beneath the frame to each selectively rotate a drive wheel. The frame is supported on forward and rear wheel assemblies with a supporting wheel. The transaxles are supported beneath the frame and pivotally secured thereto by a flange captivating vibration pillows and proximate the driven wheel and an inner pivot rod secured to the frame by apertures in downwardly depending tabs.

The present invention is directed to providing a strut suspension system configured to improve a steering property by reducing steering frictional resistance when a steering wheel is rotationally manipulated and having a relatively simple mechanical structure to reduce the number of components and manufacturing costs and to secure a large space for installing main components such as an engine and the like.

Disclosed is a strut suspension system configured to absorb impact and vibrations transferred to a vehicle body from a road surface through a wheel. The strut suspension system includes a strut provided between the vehicle body and the wheel and to which a knuckle arm connecting a steering system of a vehicle to the wheel is connected to be relatively rotatable when the steering system performs steering and a stabilizer link having one end connected to a stabilizer bar configured to increase roll rigidity of the vehicle body and the other end coupled to prevent the strut from rotating.

A universal assembly platform for lightweight vehicles, wherein the platform comprises a main vehicle chassis structure, a front suspension system connected to the main vehicle chassis structure and to which one or more front wheel assembly is mountable, and a rear suspension system connected to the main vehicle chassis structure and to which one or more rear wheel assembly is mountable. The rear suspension system is connected to the main vehicle chassis structure such that when the one or more rear wheel assembly is mounted to the rear suspension system a rear wheel of the one or more rear wheel assembly defines the distal end of an overall length of the vehicle.

A socket joint having an offset housing configuration and reduced stud diameter can improve steering performance while being able to mate with standard vehicle components. In one implementation, the joint has an offset configuration along with a spherical bearing, where a central housing axis is radially offset from a central stud axis. With the offset configuration, the size of the stud is smaller than with typical joints. In one embodiment, a ratio of the housed stud diameter to the housing outer diameter is between 1:1.5 and 1:2.72. In some implementations, there is a transition surface between the housed stud portion and an attachment stud portion on the stud. One or more helical oil grooves may be located between the transition surface and a retaining ring groove. The retaining ring groove can be used to situate a retaining ring that holds the stud assembly together.

The invention relates to a connection system for connecting a damper unit of a vehicle inside a wheel suspension of the vehicle, the connection system having: an upper attachment region for attaching the damping unit, at least part of said region surrounding a receiving area for the damping unit and the receiving area extending around a first axis acting as the damping axis of the damping unit; a lower attachment region for coupling to the wheel-side portion of the wheel suspension, said lower attachment region having, in particular, two mutually spaced lower sections with an attachment area therebetween and an intermediate region which connects the upper attachment region to the lower attachment region. The main extension of the intermediate region corresponds to the direction of the first axis and the intermediate region allows the passage of a drive shaft of the vehicle. The connection system is made of an extruded part, the extrusion direction of which is the direction in which the extruded material extends, said material thus forming the intermediate region of the connection system. The invention also relates to a connection system comprising a clamping mechanism.
