Hinging arrangement for a wheel axle suspension

A wheel axle suspension for a vehicle, comprising a longitudinal suspension arm to which the axle is fixed, a bearing bracket fixed to the vehicle chassis and an air spring bearing against the vehicle chassis, wherein the suspension arm, seen in the driving direction of the vehicle, on its rear end is attached to the air spring and on its front end is hingedly attached to the bearing bracket, and furthermore comprising a shock absorber which is hingedly coupled to a fixed component of the vehicle by means of a hinging arrangement comprising an attachment eye fixed to the shock absorber to be hingedly attached to the vehicle, and a hinge pin attached to a fixed vehicle component, 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, 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, said resilient ring 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.

• wherein the attachment eye has a bore for the hinge pin which comprises at least one tapering bore portion, the 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, said resilient ring bearing 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 the side plates such that the central bore therein 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 the inner sides of the dents are received in the respective tapering bore portion of the eye, and wherein the clamping members are received in the outer side of the respective dents, said clamping member being forced against the outer side of the 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 surface of the tapering bore portion of the attachment eye.
