A modular chassis is provided for an off-road vehicle to improve assembly, servicing, and repairing of a drivetrain of the off-road vehicle. The modular chassis includes a chassis to support components of the off-road vehicle. A front frame module couples with a front of the chassis, and a rear frame module couples with a rear of the chassis. The front frame module supports lower suspension arms of the off-road vehicle by way of inboard bushing joints. The front frame module supports at least a steering gear and a front differential of the off-road vehicle. The rear frame module is a tube-frame structure that supports components of the off-road vehicle. A lower portion of the rear frame module extends rearward and acutely upward to a top frame member that couples with upper side portions of the chassis. Several cross-members impart structural integrity to the rear frame module.

A towed or semi-mounted agricultural machine having a chassis on which an axle device connecting two wheels to the chassis is mounted, this axle device being provided with at least one movable part and one fixed part in such a way that the spacing between the wheels can be modified, at least one of the wheels being integral with a movable part that is connected slidingly along a longitudinal axis to the fixed part, which is integral with the chassis. Each movable part is additionally connected mechanically to the chassis by a respective articulated link, which is articulated on the one hand with the movable part by a first articulation and on the other hand with the chassis by a second articulation.

A wheel support for a motor vehicle, including a main part and a track lever extending from the main part for attaching a track rod via a track rod joint, wherein the track rod joint is fixed or can be fixed to the track lever at an attachment point by a pin on one side of the track lever. A holding protrusion which covers the attachment point forms a securing means for the track rod on the wheel support. The disclosure additionally relates to a method for mounting a wheel support for a motor vehicle.

A low suspension arm strut coupling is provided for a suspension of an off-road vehicle. The suspension comprises a lower suspension arm that is hingedly coupled between a chassis of the off-road vehicle and a spindle assembly that is coupled with a front wheel. An upper suspension arm is hingedly coupled between the chassis and the spindle assembly. A strut is coupled between the lower suspension arm and the chassis. A lower pivot couples the strut to the lower suspension, and an upper pivot couples the strut to the chassis. The upper and lower pivots provide a lower center of gravity of the off-road vehicle and a relatively smaller shock angle. The lower suspension arm is reinforced to withstand forces due to movement of the front wheel and operation of the strut in response to travel over terrain.

A shock absorber mounting assembly for an off-road vehicle is provided. The shock absorber mounting assembly provides a shock absorber adapter bracket that selectively interconnects a lower portion of the shock absorber and the original equipment manufacturer A-arm of the off-road vehicle. The present invention thus enables any model year shock absorber to be adapted to operatively associate with the steering system of any off-road vehicle of the same make and model, regardless of model year. The shock absorber adapter bracket may be of unitary construction of resilient material adapted to provide a main portion for selectively and rotatably connecting the original shock fork, wherein two fork portions of the shock absorber adapter bracket operatively associate with the lower portion of the shock absorber.

A chassis component for a wheel suspension which has a strut arrangement with at least one strut which is in the form of a profile component with an open cross-section. The at least one strut has a profile base and two wall sections that extend away from the profile base. An articulation point is provided, at least at one end of the strut, for receiving two joint components movably connected to one another, namely, a first joint component having a spherical joint body and a second joint component that rotatably and/or pivotably holds the joint body. In the area of the at least one articulation point, the wall sections have first and second joint accommodation apertures arranged opposite one another. A cylindrical sleeve is pressed in between the first joint accommodation aperture and the second joint accommodation aperture and keeps the opposite wall sections apart from one another.

A rod-end front suspension is provided for an off-road vehicle. The rod-end front suspension comprises a spindle assembly that is pivotally coupled with an upper suspension arm by way of a first rod-end joint and pivotally coupled with a lower suspension arm by way of a second rod-end joint. A steering rod-end joint coupled with the spindle assembly pivotally receives a steering rod. An axle assembly coupled with the spindle assembly conducts torque from a transaxle to a wheel coupled with the spindle assembly. Each of the first and second rod-end joints comprises a ball rotatably retained within a casing. The ball is fastened within a recess between parallel prongs extending from the spindle assembly. A threaded shank extending from the casing is threadably fixated with the suspension arm, such that the spindle assembly may be moved with respect to the casing and the suspension arm.

A front suspension structure of a vehicle where an appropriate locus of a front wheel when going over undulating ground, an arm span, and an arm length can be secured. Left and right first arms are rotatable about a rotation axis extending forward and obliquely toward a center in a left-right direction in a plan view and passing through two proximal parts. A frame front section has left and right front coupling parts to which proximal parts of front rods of left and right upper arms are coupled respectively. A distance between the left and right front coupling parts is smaller than a width in a left-right direction of a housing of a differential gear.

A chassis component for a wheel suspension, having a strut arrangement with at least one strut which has a profile with an open cross-section. The at least one strut has a profile base and two wall sections which extend away from the base. An end of the strut has an articulation point that receives a first joint component having a spherical joint body and a second joint component which holds the joint body so as to rotate and/or pivot. A first joint accommodation aperture and a second joint accommodation aperture are arranged, in the area of the articulation point, opposite one another. The joint body is positioned via a circular-segment-shaped fastening element arranged on the joint body between the joint accommodation apertures. The joint accommodation apertures and the joint body positioned between them are integrated in a joint housing produced by overmolding, which forms the second joint component.

A structural panel joining part for a vehicle having an underbody hold-down panel, a floor panel, a dash panel, and a cowl side panel includes an underbody coupling first portion configured to couple to at least one of the underbody hold-down panel and the floor panel, a dash panel coupling second portion configured to couple to the dash panel, and a cowl side coupling third portion configured to couple to the cowl side panel. The structural panel joining part maintains structural integrity between the underbody hold-down panel, the floor panel, the dash panel, and the cowl side panel to provide structural reinforcement during small overlap rigid barrier impacts to facilitate reducing structural intrusion into an occupant compartment of the vehicle.
