An off-road vehicle includes a chassis, an axle carriage, a rigid axle and a pair of suspension cylinders. The axle carriage is attached to or forms a part of the chassis, and includes a generally vertically arranged slot. The rigid axle is mounted to the axle carriage with a wheel hub at each end thereof, and is vertically movable relative to the axle carriage. The suspension cylinders are connected between the axle carriage and axle, and are operable to move the axle in vertical directions relative to the axle carriage. The off-road vehicle is characterized in that the axle includes a first pair of roll angle stops which engage the axle carriage when the axle is at or near a fully lowered position relative to the axle carriage, and a second pair of roll angle stops which engage the axle carriage when the axle is at or near a fully raised position relative to the axle carriage.

A motor vehicle includes a bodywork structural element and a running gear, such as a vehicle back end, that includes at least one arm. The at least one arm includes a top attachment end that is received in a sheet metal clevis supported on a bottom surface of a floor of the bodywork structural element. The attachment end includes at least one transverse tubular sleeve that is received with reduced play between two parallel flanks of the clevis, and an attachment screw capable of passing through two coaxial bores of both flanks and the transverse tubular sleeve to enable attachment of the attachment end into the clevis. The clevis guides the attachment end into a position for aligning the bores of the flanks and the sleeve.

A steering assistance system for an agricultural vehicle includes a rigid axle on which steerable wheels are mounted and which is mounted so as to float relative to a supporting vehicle structure. The system includes a steering angle sensor for detecting a steering angle of the steerable wheels, a swing angle sensor for determining a swing angle of the rigid axle relative to the supporting vehicle structure, an actuating arrangement for influencing the steering angle, and a control unit that calculates a threshold value permissible for the steering angle depending on the detected swing angle. If the detected steering angle exceeds a tolerance range specified for the threshold value, the control unit executes steering interventions for reducing the steering angle by activating the actuating arrangement to satisfy the threshold value.

A motor vehicle rear structure includes an underframe component for supporting a motor vehicle floor, an axle component including a central part and two lateral parts that define, with the central part, a space to accommodate a component of the vehicle, and a pivot member including a first pivot element and a second pivot element which are able to pivot relative to one another. The rear structure is arranged such that the first and second pivot elements pivot relative to one another about an axis that is substantially horizontal and substantially perpendicular to a direction of travel of the vehicle in a frame of reference of the motor vehicle, when the first and second pivot elements are thus fixed to the central part of the axle component and to the underframe component of the motor vehicle, respectively.

A vehicle includes a support structure and a suspension for an oscillatingly supported, rigid axle body. The suspension has a suspension device which is located between the axle body and the support structure and acts in a height direction of the vehicle. The vehicle further includes a plurality of coupling sites and a transverse link extending in a transverse direction of the vehicle. The transverse link is coupled to the support structure via a first link area and via a second link area and a pendulum support to the axle body. The transverse link includes a third link area which, with reference to the pendulum support in the transverse direction of the vehicle, is located opposite the first link area and is flexibly connected with a coupling site of the suspension device.

A motor vehicle rear structure includes an underframe component for supporting a motor vehicle floor, an axle component including a central part and two lateral parts that define, with the central part, a space to accommodate a component of the vehicle, and a pivot member including a first pivot element and a second pivot element which are able to pivot relative to one another. The rear structure is arranged such that the first and second pivot elements pivot relative to one another about an axis that is substantially horizontal and substantially perpendicular to a direction of travel of the vehicle in a frame of reference of the motor vehicle, when the first and second pivot elements are thus fixed to the central part of the axle component and to the underframe component of the motor vehicle, respectively.

Described herein are methods and systems of a chassis of a commercial electric vehicle. In various embodiments, the chassis may include a ladder frame with a plurality of frame rails. Batteries and drive units may be packaged within the frame rails of the ladder frame. The chassis may further include an independent front suspension and batteries may be disposed between the suspension members of the independent front suspension.

A rear axle of a commercial electric vehicle includes a curved de Dion axle that includes stub axles, CV cups, each configured to receive a portion of a CV axle, and a central portion disposed downward and rearward of the stub axles. The rear axle includes a curved form factor to allow for a portion of an electric drive unit to be disposed in a manner where a hub centerline connecting the stub axles intersects the electric drive unit.
