Abstract

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.

Claims16

Dependent claims

A vehicle wheel axle suspension, comprising a longitudinal suspension arm to which a vehicle axle is fixed, a bearing bracket fixed to a vehicle chassis and an air spring bearing against the vehicle chassis, wherein the suspension arm, seen in a driving direction of the vehicle, on a rear end is attached to the air spring and on a front end is hingedly attached to the bearing bracket by means of a hinging arrangement, comprising an attachment eye integral to the suspension arm, and a hinge pin attached to the bearing bracket, which 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 having a tapering bore portion, the hinging arrangement further comprising 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 and bears with one side against the tapering surface of said tapering bore portion,
wherein the bearing bracket comprises two substantially parallel side plates provided with holes for passing through the hinge pin, wherein the attachment eye of the suspension arm is located between said side plates such that the bore in the attachment eye and the holes in the side plates are brought in line,
wherein in each of the side plates is formed an inwardly projecting dent, wherein inner sides of the dents are received in the respective tapering bore portion of the attachment eye, and wherein the clamping members are received in outer sides of the respective dents, said clamping member being forced against the outer side of the respective dent whereby the resilient ring is compressed between the dent and the tapering surface of the tapering bore portion,
wherein on the inner side of the dent is arranged the resilient ring, which is made of rubber vulcanised on a dish-shaped metal ring, and
wherein the metal ring is facing the side plate and the rubber is facing the tapering bore portion surface of the attachment eye.
