A drivable axle for a vehicle, in particular a rigid axle. The drivable axle has an axle body designed to accommodate an axle shaft and a receiving structure for receiving a vehicle element which is integrated into a drive-train of the vehicle. The receiving structure is connected to the axle body and is designed to receive a drive unit of the vehicle and has openings for connection to the axle shaft. The receiving structure has at least one fixing area for fixing the drive unit to the receiving structure.

A tandem axle suspension system includes a first leaf spring having a first eye end and a second eye end, a second leaf spring having a third eye end and a fourth eye end and an assembly for converting double eye leaf springs of a tandem axle suspension system into slipper springs. That assembly includes a keeper including a first guide track and a second guide track, a first follower adapted for receipt of the first eye end and sliding movement along the first guide track and a second follower adapted for receipt of the third eye end and sliding movement along the second guide track.

A suspension travel control system for a vehicle suspension is disclosed. The suspension travel control system includes a stop post secured to the vehicle frame and a suspension travel control formation that includes a base and a body. The stop post is positioned in a space defined by the body. The suspension travel control formation may be secured to the axle, the main support member or incorporated into the axle coupling assembly to provide a rebound and jounce stop as well as longitudinal redundancy in the event of the failure or loss of a longitudinal linkage.

A leaf spring device (1) for a vehicle having a first spring leaf (2) made of a fiber reinforced plastic and at least one further spring leaf (3). The first spring leaf (2) and the further spring leaf (3) interact with one another to implement a progressive suspension. The first spring leaf (2) has a receiving space (4) and the further spring leaf (3) is arranged in the receiving space (4) so as to implement the progressive suspension and/or to increase stability when using such a leaf-spring device (1).

A clamping system for mating an I-Beam frame to an undercarriage is disclosed. The clamping system utilizes clamping brackets to secure the undercarriage to the trailer frame. The undercarriage has adapter sides oriented perpendicular to the undercarriage adapter bottom. The clamping brackets have two portions oriented perpendicular to each other. Holes are located in the clamping brackets to receive bolts or screws. The trailer frame is aligned onto the undercarriage and positioned such that proper tongue weight is applied. The clamping brackets are rigidly installed on the clamping bracket sides. Clamping screws are installed into the clamping brackets and torqued to a value such that a compressive force is applied between the bottom of the I-Beam and the undercarriage adapter bottom. The compressive force applied prevents unwanted relative motion between the I-Beam frame and the undercarriage during use.
