An outer ring of an inner joint of the constant speed transmission shaft is provided with a vehicle speed sensor rotating synchronously with the inner joint, and the drive axle is fixedly equipped with a signal collecting device opposite to the vehicle speed sensor and configured to monitor a rotation speed signal of the vehicle speed sensor. The inner joint of the constant speed transmission shaft transmits torque during the running of a vehicle, and through monitoring a rotation speed of the inner joint, the rotation data of rear wheels can be obtained. By mounting the vehicle speed sensor on the inner joint and fixing the signal collecting device on the drive axle for monitoring the rotation speed signal of the vehicle speed sensor, the signal reading is stable, which facilitates the maintenance, reduces the cost, and can satisfy the environmental requirements.

An apparatus and a method are provided for an offset tie rod joint for vehicle steering systems. The offset tie rod joint comprises a ball rotatably retained within a casing that is disposed in an opening of an offset housing. A threaded shank fixedly coupled with the offset housing is received by a steering rod. The opening is displaced from a longitudinal axis of the threaded shank by a distance that provides clearance between the offset housing and a spindle assembly during articulation of the spindle assembly during steering. A rear backstop and a front snap-ring in a groove retain the casing within the opening. A bore extending through the ball receives a bolt that fixates the ball between parallel prongs of the spindle assembly. A misalignment spacer on each side of the ball provides clearance for rotation of the ball within the offset housing.

A wheel suspension (1) for a wheel (23) of a vehicle, in particular the rear wheel of a utility vehicle, driven by an electric or pneumatic motor (2), having a swing arm (3) which is mounted pivotably around a pivot axis (7) on the vehicle in a first region (4) and is supported on the vehicle in a second region (8), wherein a third region (10) of the swing arm (3) carries a part of the motor (2) which is rotationally fixed in relation to the swing arm (3) in order to transmit a torque to the wheel using a rotating part of the motor (2).

A movable structure driving unit is a movable structure driving unit used for a movable structure, including: an electric motor that is electrically connected to a power supply and that drives a front wheel; a rear-side motive power source that drives a rear wheel; a jump detector that detects a jump of the front wheel from ground; and a motor controller that controls driving of the electric motor. The motor controller stops supply of a driving current from the power supply to the electric motor when the jump of the front wheel from the ground is detected in a state in which driving of the front wheel and the rear wheel is instructed.

A suspension device for an in-wheel motor driven wheel ensures a lever ratio and stroke of a shock absorber without setting the upper end portion of the shock absorber at a high position. A wheel driven by an in-wheel motor unit is suspended on a vehicle body via a suspension structure member and a shock absorber, the suspension structure member including an upper suspension arm pivotally supported with respect to the vehicle body, and a third link. The third link pivotally connects the upper suspension arm to the wheel while having a shock absorber connecting portion to which the lower end of the shock absorber is connected. Further, the shock absorber connecting portion is disposed in the vehicle bottom position lower than an upper end surface of the in-wheel motor unit.

Provided is a trailing arm riding mower suspension system that includes trailing arms adapted to support hydraulic motor units and having leading ends pivotally coupled to a mower frame by way of leading end spherical joints and trailing ends having hydraulic drive unit mounts, where the trailing arms are adapted to pivot about leading end pivot locations defined by the leading end spherical joints.

An unmanned ground-based hygiene maintenance vehicle, UGV, includes a housing with a base plate, top plate and housing side wall substantially perpendicular to the base plate. Arranged in the housing is at least one wheel drive coupled to at least one wheel in a recess in the base plate. The UGV includes sensors for sensing the environment of the UGV, and a controller for autonomous location and navigation of the UGV based on sensing parameters of the sensors. The UGV includes an articulated robot arm on the top plate of the housing and to support a hygiene maintenance tool. The UGV includes at least one load-receiving element coupled to the housing side wall and extending outwards from the housing side wall, wherein the load-receiving element includes a load support surface for supporting a hygiene maintenance tool supply module with respect to a vertical direction extending transverse to the base plate.

A suspension structure includes a pair of trailing arms (12), a beam member (13) connecting the pair of trailing arms, a bracket (21) connected to a rear end region of the trailing arm, and an in-wheel motor drive device (31) coupled and fixed to the bracket. The in-wheel motor drive device (31) is located above the rear end region of the trailing arm (12), and a lower side of the in-wheel motor drive device (12) is covered by the rear end region of the trailing arm (12) and the bracket (21).

A method for controlling the safe operation of a rear axle of a set of combined axles powered by a motor vehicle, particularly for a vehicle designed to carry loads and which have 6×4, 8×4 or 10×4 type traction configurations, or tridem models formed by three drive axles. The method includes a set of steps and activities that ensure proper and safe operation of systems and mechanisms for uncoupling and raising a rear axle of a vehicle, and more specifically checking a status of certain operating parameters of the rear axle and of the vehicle itself in order to permit or prevent uncoupling and coupling, as well as raising and lowering of the rear axle of the vehicle.

A suspension system for a vehicle having a frame includes a first interface member configured to be positioned on a first lateral side of the frame and a second interface member configured to be positioned on an opposing second lateral side of the frame. The first interface member and the second interface member are positioned along a common central axis. The suspension system also includes a first swing arm coupled to the first interface member and configured to rotate about the common central axis, a second swing arm coupled to the second interface member and configured to rotate about the common central axis, and a sway bar coupled to the first interface member and the second interface member. The sway bar is positioned coaxially with the common central axis and extends between the first swing arm and the second swing arm.
