One aspect of this disclosure is directed to a Steering system comprising a housing in inch a steering rack is movably arranged and extends out of the housing on at least one side of the housing with a steering rack end portion. The steering rack being connected to a tie rod with a ball joint. At least the sections of the steering rack extending outside of the housing and the ball joint are covered by at least a protective bellows defining a central axis and the bellows further comprising a first bellows end defining a first bellows opening around the central axis and a second bellows end defining a second bellows opening around the central axis. The bellows is arranged inside a puncture resistant cover. The cover comprises a first cover end defining a first cover opening around the central axis and a second cover end defining a second cover opening around the central axis. At least one of the cover ends comprises at least one loop at least partially extending around the least one cover end and in which loop a clamp to fasten the cover end is arranged. The first bellows end and the second bellows end are arranged between the first cover end and the second end. Another aspect of this disclosure is directed to a puncture resistant cover with an elongated tubular shape along a central axis. The cover comprises a first cover end defining a first cover opening around the central axis and a second cover end defining a second cover opening around the central axis. At least one of the cover ends comprises at least one loop at least partially extending around the least one cover end and in which loop a clamp to fasten the cover end is arranged.

A steering device includes a rack shaft that turns wheels, a bush slidably support the rack shaft, tie-rods joined to the rack shaft, boots that cover a joining portion that joins the rack shaft and the tie-rod. A protrusion part is formed on either one of the bush and a rack housing so as to protrude toward the other. A restriction groove into which the protrusion part is inserted is formed on the other. A space inside the first boot and a space inside the second boot constantly communicate with each other via the restriction groove.

A rack and pinion assembly for a steering assembly is disclosed. The rack and pinion assembly has: a housing; a rack disposed in the housing, the rack being translatable in the housing; a pinion engaging the rack for causing translation of the rack; and at least one rolling element connected to the rack. The at least one rolling element is translatable with the rack. The at least one rolling element rolls along an inner surface of the housing as the rack translates. A steering assembly having the rack and pinion assembly and a vehicle having the steering assembly are also disclosed.

The tie rod assembly union includes a tube sleeve and a tie rod shaft that extends into the tube sleeve such that the tie rod shaft and the tube sleeve overlap with one another. In the overlapping area, each of the tie rod shaft and the tube sleeve has at least one set of openings. A C-shaped clamp is disposed about the tube sleeve. The clamp has a curved inner surface which engages both tube sleeve halves. The clamp has a first set of apertures which are spaced outwardly from the curved inner surface and a second set of apertures which extend to the curved inner surface. A first fastener extends through the first set of apertures to tighten the clamp onto the tube sleeve. A second fastener extends through the second set of apertures and through aligned openings in the tie rod shaft and tube sleeve.

A coupling device includes two coaxial shafts, namely a tubular outer shaft and an inner shaft, capable of rotating about a reference axis; a wrap-around raceway formed on a first one of the coaxial shafts; an oblique raceway formed on the second coaxial shaft and a play take-up rail provided with a complementary raceway and movable relative to the second coaxial shaft parallel to a plane perpendicular to the reference axis. A row of balls is positioned to run parallel to the reference axis on the wrap-around raceway, the oblique raceway and the complementary raceway, to guide the two coaxial shafts relative to each other in translation.

Work vehicle axle device includes a wheel drive case utilizing a centrally disposed vertically extending first coupling portion, a centrally disposed vertically extending second coupling portion spaced from the first coupling portion and an input shaft located below an upper end of either the first or second coupling portions and being configured to transmit rotational power to wheels. The first and second coupling portions are configured to pivotally mount to the wheel drive case to a vehicle body of the work vehicle in a manner that allows the wheel drive case to pivot about an axis that, when viewed from above, is at least one of parallel to a front to back direction of the vehicle body and parallel to a centrally disposed front to back axis of the vehicle body.

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.

Disclosed is a vehicle having a breakaway tie rod. The tie rod has a longitudinal axis oriented substantially orthogonal to the longitudinal axis of the vehicle, and includes a rod portion and a receiver portion. The rod portion includes a proximal ball joint disposed at the proximal end and a male coupling section disposed at the distal end. The receiver portion includes a female coupling section disposed at the proximal end, a distal ball joint disposed at the distal end, and a narrowing feature disposed between the proximal end and distal end. The male coupling section of the rod portion is received into the female coupling section of the receiver portion, forming a connection, and the distal end of the rod portion is disposed proximate to the narrowing feature. The narrowing feature is configured to fracture when subjected to a threshold force substantially parallel to the longitudinal axis of the vehicle.

A rack and pinion steering system includes a housing, a rack, a pinion gear, and a radially preloaded rack bearing. The rack is supported by the housing, and the pinion gear is meshed to the rack. The radially preloaded rack bearing is supported and preloaded to the housing and is preloaded to the rack.
