A vehicle weight measurement device includes a moving body, an attachment body, a stopper ring provided between the moving body and the attachment body, and a rotation prevention part configured to prevent the moving body and the attachment body from rotating relative to each other. The stopper ring includes a fixing part fixed to one of the moving body and the attachment body and a separation and detachment prevention part provided at the other of the moving body and the attachment body and configured to prevent the moving body and the attachment body from separating and detaching, without inhibiting movement of the moving body. The rotation prevention part includes a pin fitted from the moving body to the attachment body.

A vehicle suspension assembly includes an axle member, a pair of mounting brackets configured to couple to a vehicle frame, and a trailing arm arrangement that includes a first trailing arm portion having a first end pivotably coupled to one of the pair of mounting brackets, and a second end rotationally coupled with the axle member at a first position, a second trailing arm portion having a second end pivotably coupled to the other of the pair of mounting brackets, and a second end rotationally coupled with the axle member at a second position, and a first torsional member having a first end fixedly coupled to the first trailing arm portion and a second end fixedly secured to the axle member at a third position, the first torsional member configured to transmit torsion of the axle member to the first trailing arm portion.

A vehicle suspension may include a crank bar and first and second lateral links. The crank bar is mounted to an axle assembly and is rotatable relative to the axle assembly about a first axis. The first lateral link may include a first end rotatably coupled to a first bracket fixed to a chassis of the vehicle and a second end coupled to the crank bar for rotation about a second rotational axis. The second lateral link may include a third end rotatably coupled to a second bracket fixed to the chassis and a fourth end coupled to the crank bar for rotation about a third rotational axis. A straight line having an infinite length may intersect the first rotational axis and one of the second and third rotational axes does not intersect the other of the second and third rotational axes.

Disclosed herein is an adjustable suspension mount system that includes a subframe for attachment to a suspension device of a vehicle. The system further includes a first and second mount link for attaching the subframe to a frame of a vehicle. A positioning device for attaching to the frame of the vehicle and the subframe is also included. The adjustable suspension mount system may also attach to a second suspension device of the vehicle as well as other further suspension devices. Further disclosed is a vehicle having the adjustable suspension mount system, a kit for providing the adjustable suspension mount system, and methods of using the adjustable suspension mount system for raising and lowering a vehicle.

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 suspension assembly for a commercial vehicle includes a first linkage, an air spring, a carriage, and a second linkage. The first linkage is pivotally coupled at a first end with a structural member of a frame. The structural member extends downwards from the frame. The air spring is coupled with the frame and a second end of the first linkage. The air spring drives the first linkage to pivot about the first end relative to the structural member. The carriage is pivotally coupled with the first linkage at a position between the first end and the second end of the first linkage. The second linkage is pivotally coupled at a first end with the structural member, and pivotally coupled with the carriage at a second end. The structural member, the first linkage, the second linkage, and the carriage define a four-bar linkage.

A suspension assembly includes a first linkage rod coupled between an axle housing and a first frame rail, and a second linkage rod coupled between the axle housing and a second frame rail. The first linkage rod is arranged at an angle relative to a central longitudinal axis so that as the first linkage rod extends from the axle housing toward the first frame rail, the first linkage rod angles laterally outwardly and away from the central longitudinal axis. The second linkage rod is arranged at an angle relative to the central longitudinal axis so that as the second linkage rod extends from the axle housing toward the second frame rail, the second linkage rod angles laterally outwardly and away from the central longitudinal axis.
