The present invention relates to a motorized machine having a chassis, a suspension system mechanically coupled on the one hand to a wheel of the motorized machine and on the other hand to the chassis, and a steering system configured to transmit the steering to said wheel of the motorized machine through the suspension system, the steering system being in a slide-type mechanical connection with the suspension system along the axis of the suspension system.

A vehicle includes a chassis and a front axle assembly. The chassis includes a first frame rail defining a first vertical plane and a second frame rail defining a second vertical plane. The front axle assembly includes an axle and a steering assembly. The axle is coupled to a front end of the first frame rail and the second frame rail. The steering assembly includes a pair of wheel hubs coupled to opposing ends of the axle, a steering gear mechanism including a first gear box and a second gear box, and a linkage assembly coupling the steering gear mechanism to the pair of wheel hubs to facilitate steering the pair of wheel hubs through actuation of the steering gear mechanism. The first gear box and the second gear box are positioned between the first vertical plane and the second vertical plane.

The present disclosure relates to a shaft adapted to be at least partially inserted into an opening of a shaft receiver. The shaft comprises a nominal shaft portion adapted to be at least partially inserted into the opening of the shaft receiver, followed by an intermediate shaft portion that in turn is followed by a guide shaft portion terminating the shaft. The shaft comprises a cross-section with a cross-sectional contour in a plane including the central axis, the cross-sectional contour comprising a nominal shaft portion contour of the nominal shaft portion, an intermediate shaft portion contour of the intermediate shaft portion and a guide shaft portion contour of the guide shaft portion. The cross-sectional contour comprises a radial direction being perpendicular to the central axis, wherein, as seen in the radial direction, the nominal shaft portion contour is located at a nominal radial distance from the central axis.

A wheel-mounting assembly for an agricultural utility vehicle includes a chassis and a telescopic axle arrangement fixed to the chassis. The telescopic axle arrangement includes an inner axle telescopically received in an outer axle, which is fixed to the chassis. A wheel-support assembly is mounted to an outboard end of the inner axle. A steering-control actuator is connected between the inner axle and the wheel-support assembly. The steering-control actuator is connected to the inner axle through an opening provided in the outer axle, which allows the steering-control actuator to translate together with the inner axle when track width is adjusted.

A tie rod boot includes a minimally thick accordion shaped bellows section. One terminal end of the boot is secured to a steering mechanism and the other is secured to a tie rod. Protuberances are provided and are strategically located on the bellows walls for resisting impacts from rocks and other debris and minimizing holes through the tie rod. When the bellows is retracted and pairs of opposing bellows walls collapse towards each other, the protuberances of adjacent opposing walls nest with each other and contact the opposing wall. The protuberances can be step shaped rings or a ring of discrete protuberances which are step shaped or both. The step shaped protuberances are defined by a riser surface extending along a plane which is substantially perpendicular to the longitudinal axis of the boot and a tread annular surface which is substantially parallel with the longitudinal axis.

A rack assembly for a vehicle steering system includes a first rack component extending longitudinally from a first outer end to a first inner end, the first rack component having a first shoulder extending radially outwardly from a neck region to a head region. The rack assembly also includes a second rack component extending longitudinally from a second outer end to a second inner end, the second rack component having a second shoulder extending radially outwardly from a neck region to a head region. The rack assembly further includes a coupling assembly having an inner surface defining a hollow region that the head region of the first rack component and the head region of the second rack component are each disposed within, the inner surface having a first radial protrusion in abutment with the first shoulder and a second radial protrusion in abutment with the second shoulder.

A rack bar assembly for a rack electric power steering system is provided. The rack bar assembly includes a first rack bar extending axially. The rack bar assembly also includes a second rack bar extending axially, wherein the first rack bar and the second rack bar are spaced a radial distance from each other and oriented parallel to each other.

A vehicle includes a chassis and a front axle assembly coupled to a front end of the chassis. The chassis includes a first frame rail and a second frame rail. The first frame rail defines a first vertical plane. The second frame rail is spaced from the first frame rail and defines a second vertical plane. The front axle assembly includes a solid axle and a steering assembly. The steering assembly includes a pair of wheel hubs, a steering gear mechanism, and a linkage assembly. The pair of wheel hubs are coupled to opposing ends of the solid axle. The pair of wheel hubs are configured to facilitate coupling wheels to the front axle assembly. The steering gear mechanism is positioned between the first vertical plane and the second vertical plane. The linkage assembly couples the steering gear mechanism to the pair of wheel hubs.

A steering system includes a steering control, a steering assist assembly, and two anti-rotation arms. The steering assist assembly includes a housing includes two hollow cylinders formed therein. A piston is slidably arranged within the first cylinder and an axial rod is slidably arranged within the second cylinder. First and second tie rods are connected to first and second axial ends of the axial rod. A shaft operably connected to the steering control is configured to engage with the axial rod such that rotation of the shaft causes axial movement of the axial rod. The axial movement of the axial rod causes axial movement of the first and second tie rods so as to turn the wheels of the vehicle. The anti-rotation arms are operably connected to the piston and to the axial rod and are configured to prevent rotation of the piston and the axial rod.

A work vehicle includes a chassis defining a longitudinal axis, a prime mover configured to move the chassis in the direction of the longitudinal axis, and a steering assembly configured to pivot a wheel relative to the chassis. The steering assembly includes a knuckle coupled to the wheel, a tie rod coupled to the knuckle and having a ball portion, a steering cylinder, and a joint assembly. The steering cylinder is slidably coupled to the chassis and configured to translate relative to the chassis along a cylinder axis perpendicular to the longitudinal axis. The steering cylinder includes a connection portion having an inner circumferential surface that partially defines a bearing pocket. The joint assembly couples the ball portion to the connection portion and includes a bearing race that is received into the bearing pocket in direct contact with the inner circumferential surface. The bearing race receives the ball portion.
