A hub carrier includes a front arm part extending toward an inner side of the vehicle on a front side of the vehicle relative to an axle of the rear wheel; and a rear arm part extending on a rear side of the vehicle relative to the axle of the rear wheel. The rear arm part is joined to a lateral beam, extending in a vehicle width direction, on the rear side of the vehicle relative to the axle of the rear wheel. A vehicle rear end portion of a trailing arm, extending in a vehicle front-rear direction, is joined to the lateral beam. A vehicle front end portion of the trailing arm is joined to a vehicle body by using a first bush. A front arm part is joined to a front arm attachment part disposed on the trailing arm by using a second bush. A first support shaft of the first bush and a second support shaft of the second bush have respectively axial directions oriented differently from each other.

A method and apparatus for adapting a vehicle rear suspension wherein the apparatus comprises a substantially circular plate having first and second surfaces with a central bore therethrough and with closed and open notches extending into a circumferential edge thereof, a pair of outer mounting bores extending through the plate proximate to the circumferential edge with the closed notch therebetween and a plurality of first and second inner mounting bores distributed around the central bore. The method comprises removing a multi-link rear suspension assembly from the vehicle and removing left and right wheel assemblies from the multi-link rear suspension assembly mounting an adaptor plate to each of the left and right wheel assemblies on an inside surface thereof with a first set of fasteners, mounting an axle beam of a torsion bar rear suspension assembly to each of the adaptor plates with a second set of fasteners and securing the torsion bar rear suspension assembly to the vehicle.

A forecarriage (8) of a rolling motor vehicle (4), comprising a forecarriage frame (16), a pair of front wheels kinematically connected to each other and to the forecarriage frame (16) by means of a first kinematic mechanism (20), each wheel being connected to said first kinematic mechanism (20) by means of a respective axle journal (60), a roll block system (100) comprising a second kinematic mechanism (110) that directly connects the two wheels to one another at the respective axle journals (60) between two connection points and can assume a free configuration in which the second kinematic mechanism (110) can passively follow the movements of the two wheels with respect to each other without interfering with them and a blocked configuration in which the second kinematic mechanism (110) can set the distance between said two points thus preventing rolling movements between the two wheels while allowing pitching and steering movements.

An installation structure of an in-wheel motor unit including a motor, a speed reducer, and a housing, for installing the in-wheel motor unit on a carrier of a suspension apparatus such that the housing is sandwiched by and between the carrier and a bearing unit, wherein the bearing unit and the housing are fastened at first fastening positions, and the carrier and the housing are fastened at second fastening positions the number of which is the same as that of the first fastening positions, wherein each first fastening position and the corresponding second fastening position form a pair, so as to provide a plurality of fastening-position pairs, and wherein the first and second fastening positions of each pair are located at the same position or located close to each other when viewed in a wheel axis direction which is a direction in which a rotation axis of a wheel extends.

The vehicle suspension component includes first and second trailing arms that are spaced from one another for attachment with vehicle wheels. The suspension component also includes at least one cross-member that is rigidly connected with the first trailing arm and is operably connected with the second trailing arm in a non-rigid manner. A rotation inhibitor operably connects the at least one cross-member with the second trailing arm and resiliently resists rotation of the at least one cross-member relative to the second trailing arm.

The axle beam type suspension includes: the pair of trailing arms extending in the front-rear direction with the respective front end sections supported on the vehicle body and the respective rear end sections coupled to the wheels; the axle beam extending in the vehicle width direction and coupling the pair of trailing arms to each other; the pair of Watt's linkage mechanisms extending in the vehicle width direction, coupling the pair of trailing arms to each other at a position rearward of the axle beam, and fixed at a middle part to the vehicle body; and the inner shafts as connection members connecting the vehicle-width-direction outer end portions of one of the pair of Watt's linkage mechanisms and the other Watt's linkage mechanism. The inner shafts are characterized in that they are fixed to the trailing arms via the elastic members surrounding the inner shafts.

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces.
