The invention relates to a chassis for a utility vehicle, having a first .sup.J chassis element extending transversely with respect to the vehicle longitudinal direction and a second chassis element (5) fixed to the outer side thereof, wherein the second chassis element (5) is supported against the outer side of the first chassis element via at least one roughened supporting area (11, 12). In order to avoid relative movements between the chassis elements connected by clamping forces in a utility vehicle chassis, the roughening comprises a surface structure produced by machining the supporting area (11, 12) in a blasting process and preferably a laser beam process. The invention further relates to specific individual parts of such a chassis, specifically an axle shell, an axle guide (5), and a brake carrier.

A vehicle suspension includes at least one anchor bar, at least one axle lift spring, an auxiliary drop-type axle which may be selectively lifted or lowered and a single, integrated support attaching the at least one axle lift spring and the at least one anchor bar to the auxiliary drop-type axle, wherein the single, integrated support provides the only attachment of the at least one axle lift spring and the at least one anchor bar to the auxiliary drop-type axle, and wherein the support includes an open area configured to allow the passage of a cardan.

A hub bracket structure includes a hub bracket that connects a trailing arm and a hub carrier, wherein the hub bracket includes a bracket body that includes a mounting surface mounted with the hub carrier, and a rear connector that extends from the bracket body toward the trailing arm behind a ground contact point of a rear wheel, and the rear connector is extended to a position to overlap with a rear surface of the trailing arm in a front-rear direction and is joined to the rear surface of the trailing arm.

A leaf spring may include: an upper plate provided with arc-shaped portions which are integrally formed on both end portions thereof, respectively, for forming spring eyes; a lower plate disposed to overlap a lower side of the upper plate and provided with arc-shaped portions which are integrally formed on both end portions thereof, respectively, and face the arc-shaped portions of the upper plate to form the spring eyes; clamping units installed to restrain the both end portions of the overlapped upper and lower plates from being separated from each other; and a central fastening unit configured to fasten central portions of the overlapped upper and lower plates.

A joint for mounting an elongate element to a structural element in a vehicle, comprising a first and a second clamping portion, tightening elements configured to tighten the first and second clamping portions towards each other so that when the elongate element is arranged between the first and second clamping portions, the elongate element becomes clamped, a first and a second support portion, wherein the first and second support portions are spaced from each other and extend from the first clamping portion to the second clamping portion, wherein when the elongate element is arranged between the first and second clamping portions and the tightening elements tighten the first and second clamping portions, then at least one of the first and second clamping portions is configured to press at least one of the support portions towards the other one so that the elongate element becomes laterally contacted.

The present invention relates to a control unit for controlling a chassis system between at least a ground contact point and a frame of a vehicle, the chassis system comprising a leaf spring and a chassis arrangement, said chassis arrangement is adapted to receive a chassis condition input signal and to control a chassis condition of said chassis arrangement in response to said chassis condition input signal, said chassis system further comprising a strain gauge adapted to issue a strain gauge output signal indicative of a strain in said leaf spring, wherein said control unit is adapted to receive said strain gauge output signal and to issue said chassis condition input signal to said chassis arrangement on the basis of said strain gauge output signal. The invention also relates to a method, a chassis system, and a vehicle.

The present document provides a damper spring support and a vehicle axle having the same. The damper spring support includes: a first angle adjustment mechanism configured for being fixed to a vehicle body; a support base configured for supporting a damper spring; and a connection structure configured for detachably fixing the support base to different positions of the first angle adjustment mechanism. If the support base being fixed to different positions of the first angle adjustment mechanism, a damper spring support surface of the support base facing different directions.

A leaf spring suspension system for a vehicle includes a chassis rail. Also included is a pivot block operatively coupled to the chassis rail and rotatable relative to the chassis rail. Further included is a leaf spring operatively coupled to the pivot block proximate an end of the leaf spring. Yet further included is a half leaf spring operatively coupled to the pivot block proximate a first end of the half leaf spring and operatively coupled to a vehicle axle proximate a second end of the half leaf spring.

A joint for mounting an elongate element to a structural element in a vehicle, comprising a first and a second clamping portion, tightening elements configured to tighten the first and second clamping portions towards each other so that when the elongate element is arranged between the first and second clamping portions, the elongate element becomes clamped, a first and a second support portion, wherein the first and second support portions are spaced from each other and extend from the first clamping portion to the second clamping portion, wherein when the elongate element is arranged between the first and second clamping portions and the tightening elements tighten the first and second clamping portions, then at least one of the first and second clamping portions is configured to press at least one of the support portions towards the other one so that the elongate element becomes laterally contacted.

Axle seat assemblies and methods of manufacturing thereof, are provided for attachment to an axle body (15). The axle seat assembly may be comprised of a first piece (42) and a second piece (50). The first piece (42) may have a first wall, a second wall and a first axle seat piece engagement portion providing a first engagement surface. The second piece (50) may have a third wall and a second axle seat piece engagement portion providing a second engagement surface. The first wall and the second wall of the first piece are oriented to engage a front surface of an axle body and the third wall of the second piece is oriented to engage a rear surface (30) of an axle body. The first and second engagement surfaces of the respective first and second pieces of the axle seat assembly are positioned and configured to engage one another to removably and reversibly secure with the use of a fastener the first piece to the second piece to form an axle seat assembly.
