A tensioning device for attachment to a vehicle suspension system reduces play at ends of a pan hard bar (track bar) of the vehicle suspension system, remedying instabilities that can occur in vehicle suspensions. The device can include a bracket clamped to the pan hard bar at a point between the ends of the pan hard bar, or may be otherwise mounted to a bracket formed on the pan hard bar in OEM installations. The other end of the device is secured to the frame or the axle of the vehicle, generally near an end of the pan hard bar. The device is pre-tensioned to apply force at the ends of the pan hard bar, and includes a damping plunger to also damp forces that vibrate the ends of the pan hard bar, further loosening attachments. The tension is field-adjustable and may be tuned for various applications.

The invention relates to an axle suspension on a vehicle frame, comprising: an axle bracket which in its longitudinal direction is arranged transversely to the vehicle frame and at its longitudinal ends each is provided with a wheel carrier, a pendulum support which is connected with the axle bracket via a swivel bearing and is accommodated in a self-aligning bearing attached to the vehicle frame, wherein the swivel bearing has a swivel axis which extends parallel to the longitudinal axis of the vehicle frame.

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 haulage vehicle has a suspension system providing a flexible connection between a vehicle chassis and at least one axle housing. The system has three longitudinal link members, a transverse link member, and a resilient member adjacent each end of the axle housing; all of which are connected at one end to the vehicle chassis and at an opposite end to the axle housing. The transverse link member substantially prevents movement of the axle housing in a transverse direction, and the three longitudinal link members are substantially aligned with the longitudinal axis of the chassis and spaced apart, providing a three-point connection between the chassis and axle housing. The three-point connection keeps the axle housing in a substantially transverse orientation relative to the chassis, preventing rotation of the axle housing about the longitudinal axis of the axle housing while allowing movement of the axle housing in the vertical plane.

The chassis system may include a frame of the vehicle forming a base for the vehicle, an axle operably coupled to the frame, the axle having a first portion with a first diameter and a second portion with a second diameter, an electric motor operably coupled to the axle to propel the vehicle, one or more wheel assemblies operably coupled to the axle, and a track bar may be operably coupled to the axle via a first end and operably coupled to the frame via a second end. The second end may be linearly displaced from the first end along a reference line, and the track bar may include a hook portion defining an offset from the reference line, the offset extending away from the axle. The hook portion may extend around a transition between the first portion and the second portion of the axle.

A portal axle arrangement 1 for a motor vehicle includes at least one portal housing 2 and at least one suspension arm 5, 6. The at least one portal housing 2 includes a receiving section 7 for a portal gear and at least one connecting section 8, 9 for the at least one suspension arm 5, 6, in which the at least one connecting section 8, 9 is designed as a support section. A motor vehicle including such a portal axle arrangement is also provided.

A retrofit kit for replacing an existing leaf spring suspension system, methods of replacing the existing leaf spring suspension systems, and suspension systems may include an upper load beam having a proximal end and a distal end, the distal end being configured to pivotally mount to a vehicle. A lower control arm includes a proximal end, a distal end, and a mounting location positioned between the proximal end distal ends. The distal end of the lower control arm is configured to pivotally engage a leaf spring mounting eye provided on the vehicle. The mounting location on the lower control arm is configured to pivotally receive the proximal end of the upper load beam.
