A rear wheel steering apparatus may include: a driving part housed in a housing part; a rotating part rotated by the driving part; a moving shaft part connected to tie rods, and screwed to the rotating part; a spline plate spline-coupled to the moving shaft part so as to restrict rotation of the moving shaft part; and a space maintaining part protruding from the moving shaft part or the spline plate, and maintaining a space between the moving shaft part and the spline plate.

The socket assembly includes a housing with an inner bore which extends between open first and second ends. A ball stud is partially disposed within the inner bore of the housing and includes shank, ball and protrusion portions with the shank portion extending out of the housing through the first end. A first bearing is disposed in the inner bore and includes a passage. The protrusion portion of the ball stud extends into the passage, and the passage is shaped to cooperate with the protrusion portion to allow the ball stud to rotate relative to said housing in one rotational direction by a greater magnitude than in another rotational direction. A cover plate closes the second open end of the housing, and a spring is disposed between the cover plate and the first bearing and biases the first bearing into contact with the ball portion of the ball stud.

A leading-edge steering system is provided for a front suspension of an off-road vehicle. The leading-edge steering system is comprised of a spindle assembly that supports a drive axle assembly to conduct torque from a transaxle to a front wheel. A first rod-end joint pivotally couples an upper suspension arm and the spindle assembly, and a second rod-end joint pivotally couples a lower suspension arm and the spindle assembly. A steering rod-end joint pivotally couples a first end of a steering rod with a leading-edge portion of the spindle assembly. A steering gear is coupled with a second end of the steering rod and configured to move the steering rod, such that the spindle assembly rotates with respect to the upper and lower suspension arms. The leading-edge portion is configured to exert primarily tensile forces on the steering rod during travel over rough terrain.

An attachment interface is provided for connecting a vehicle composite component having a plate portion that is made of a fiber reinforced polymer and has a passage extending in a through manner along an axis. The attachment interface provides a metal attachment device, which includes an inner portion engaging the passage and an outer portion defining a connection point suitable to be connected to another vehicle element. The plate portion is axially sandwiched between two layers made of a fiber reinforced polymer composite material selected from the group consisting of BMC (Bulk Molding Compound), LFT (Long Fiber Thermoplastic) and DLFT (Direct Long Fiber Thermoplastic).

A tricycle for riding on any type of terrain, improving stability and safety in slow movement, having a structural chassis incorporating a rolling assembly made up of a rear wheel associated to a propulsion system and two front wheels linked to a driving handlebar, wherein the front wheels are incorporated in a height-tilting suspension, made up of articulated quadrilaterals able to be deformed independently with vertical movement depending on the individual resting of the front wheels on irregularities of the terrain, the height-tilting suspension linking to the handlebar, by means of a transmission, which links the height-oscillating movements of the articulated quadrilaterals of the height-tilting transmission with an equivalent lateral tilting of the handlebar, this transmission having a clutch which allows for enabling or disabling the linkage of the movements between the height-tilting suspension and the handlebar.

A steering system for a vehicle includes a drive motor having a motor shaft. The steering system also includes a first gear reduction stage for receiving a first rotational input from the motor shaft and providing a first rotational output. The steering system further includes a second gear reduction stage for receiving the first rotational output from the first gear reduction stage and providing a second rotational output. The second gear reduction stage may include at least one of a strain wave gearing, a worm drive, and a planetary gearing. The steering system includes an output shaft for receiving the second rotational output from the second gear reduction stage.
