Abrégé
A wheel axle suspension bearing assembly is adapted for coupling a trailing arm having an eye to a vehicle chassis, the assembly comprising a pivot bolt, a bearing bracket with spaced apart side plates having elongate holes for the pivot bolt, and an eccentric disc for adjustment of the position of the pivot bolt in the elongate holes. The eccentric disc is rotatable relative to the pivot bolt. Protrusions engage the outer contour of the eccentric disc, such that a cam drive is provided in which a rotational adjustment of the eccentric disc about the pivot bolt induces a translational adjustment of the bolt shaft in the elongate holes. The shaft of the pivot bolt is provided with a flat abutment surface that extends at least partially along a length of the shaft, and is mounted with said abutment surface in at least one of the elongated holes, and with the abutment surface parallel to the upper and lower edge surface of the at least one elongate hole. The shaft of the pivot bolt is confined between the upper and the lower edge surfaces of at least one of the elongate holes such that substantial movement of the pivot bolt in a direction perpendicular to the adjustment direction is prevented.

A method for manufacturing a wheel axle of a utility vehicle such as a trailer, semi-trailer or a truck, wherein the wheel axle comprises a hollow axle body comprising a steel tubular wall having a thickness t and having a clamping region adapted to be clamped in use between clamping parts of the vehicle suspension by means of tensioning means. An interlocking recess is formed in the clamping region. The interlocking recess is formed by a forming process wherein a stamp member is pressed into the outer surface of the tubular wall so as to form an indent. The dimension of the stamp and the pressing force are such that the surface pressure on the stamped surface portion of the tubular wall locally exceeds the yield point to form the indent and the pressing force is such that the tubular wall portion adjacent the interlocking recess is plastically sagging over a distance inwards which is at most corresponding to the thickness t of the tubular wall. Preferably the sagging distance inwards is within a range of 0 to 0,5 times the thickness t of the tubular wall. In an alternative method the interlocking recess is formed by friction drilling a blind hole in the tubular wall of the axle body.

Support for pneumatic spring of wheel axle suspension
A wheel axle suspension for suspending an axle body of a wheel axle from a vehicle, comprises on both sides of the vehicle a trailing arm which extends in the longitudinal direction of the vehicle. The axle body is attached to the trailing arms. The trailing arms are each hingedly connected at the front in the direction of travel of the vehicle to a bearing bracket which is arranged on the vehicle chassis. The wheel axle suspension furthermore comprises a pneumatic spring which is operational between the trailing arm and the chassis. A pneumatic spring support arm is provided, which is coupled to the axle body for supporting an underside of the pneumatic spring. The pneumatic spring support arm is coupled to the axle body so that the pneumatic spring support arm is mountable in a plurality of orientations with respect to the longitudinal direction of the vehicle.
The invention relates to a trailing arm mounting bracket for mounting a trailing arm to a chassis or slider assembly of a vehicle, preferably a commercial vehicle, for example a lorry or a lorry trailer, wherein the bracket comprises two side plates each having a top end, a bottom end, and an opening in the bottom end for receiving a hinge pin, which side plates are positioned opposite each other with their opening at a mutual distance for receiving an end of the trailing arm in between their respective bottom ends, said side plates being mounted with their respective top ends to an in a mounted condition vertically oriented mounting plate, which mounting plate is arranged to connect the mounting bracket to the chassis or slider assembly, and wherein a centre of the shortest distance between the two openings in the side plates lies substantially in a plane defined by the body of the mounting plate.

WHEEL AXLE SUSPENSION HAVING CLAMP BODIES WITH A PROTRUSION FOR ATTACHING AN INDENTED TUBULAR AXLE TO TRAILING ARMS
A wheel axle suspension for a vehicle comprises on both sides of the vehicle a trailing arm which extends in the longitudinal direction of the vehicle, a thin walled tubular axle body, which has attachment regions where the axle body is attached to the trailing arms. Each trailing arm is hingedly connected at the front, viewed in the direction of travel of the vehicle, to a bearing bracket which is arranged on the vehicle chassis. The suspension also comprises a pneumatic spring which is operational between each of the trailing arms and the chassis. The wheel axle suspension furthermore comprises clamp bodies for clamping the axle body at the attachment regions thereof so as to attach the axle body to the trailing arms, as well as tensioning elements for providing the clamp force for the clamp bodies. The clamp bodies engage the axle body over a certain longitudinal distance of the attachment region and around virtually its entire circumference. The axle body has a substantially circular cross section in the clamping regions and is provided with an elongated indent in each of the clamping regions. The indent extends in a longitudinal direction of the axle body. At least one of the clamp bodies is provided with a protrusion that engages in the elongated indent.
The invention relates to a vehicle comprising a trailing arm mounting bracket mounting a trailing arm to a chassis of the vehicle, preferably a commercial vehicle, for example a lorry or a lorry trailer. The invention furthermore relates to a mounting bracket and to a wheel axle suspension comprising such a mounting bracket, for use in such a vehicle. The vehicle is provided with mounting brackets comprising a top plate provided with holes for receiving bolts for mounting the bracket to the chassis. The top plate of each bracket is provided with at least one row of two or more holes for receiving chassis connecting bolts when the mounting bracket is mounted to the chassis, which at least one row, when the bracket is mounted to a chassis, extends in a direction parallel to the longitudinal direction of the vehicle. The bracket is connected to the chassis using only one row of holes, which allows for a narrow top plate.
A hinging arrangement for a wheel axle suspension of a vehicle, comprises an attachment eye fixed to a component to be hingedly attached to the vehicle, and a hinge pin, e.g. a hinge bolt, attached to a fixed vehicle component. The hinge pin is extending through the attachment eye, wherein the attachment eye has a bore for the hinge pin which comprises at least one tapering bore portion. The arrangement further comprises at least one resilient ring and a clamping member each provided with a central bore for the hinge pin, wherein, in the mounted state, the resilient ring is received at least partially within said tapering bore portion. The resilient ring is bearing with one side against the tapering surface of said tapering bore portion and said clamping member is forced against the other side of the resilient ring whereby the resilient ring is compressed between the clamping member and the tapering surface of the tapering bore portion.
