摘要:
A method of producing a trailing arm of a torsion beam axle in which an integrated drive unit of a wheel-adjacent electric drive has an electric machine and a transmission. By using the method, the trailing arm is produced in the form of a casting with a box profile. The contours for producing the area that accommodates the transmission, the connection point to the vehicle body, the bore that receives the cross-member which connects the two trailing arms to one another, the U-profile of the trailing arm, the box profile and the area that accommodates the electric machine, are modeled by cores such that the contours for producing the connection point of the trailing arm to the vehicle body, the bore that receives the cross-member and the U-profile of the trailing arm are modeled by one core.

A connection device for the torque transmitting connection of a connection component (2) to a hollow shaft (1). The connection component (2) comprises a penetrating recess (8) corresponding in shape to the outside cross section of the hollow shaft (1) for receiving one end of the hollow shaft (1), and the hollow shaft comprises a press-fit plug (9) in the area of the connection to the connection component (2) that forms an interference fit with the inner cross section of the hollow shaft (1). Preferably, the connection device is a press-fit plug (9) additionally designed as a bearing seat (10, 11) for at least one bearing (13, 14) assigned to the hollow shaft. The connection device allows durable and reliable transmission of high torques and it is possible to connect further components to the connection between the hollow shaft and the connection component. The connection device allows a reduction in construction space, mass and costs.

A twist beam axle assembly includes a twist tube and a tubular sleeve. The twist tube has a deformed portion with a non-circular cross-section positioned adjacent to an undeformed portion with a substantially circular cross-section. The tubular sleeve is positioned within and coupled to the twist beam to overlap the adjacent deformed and undeformed portions. An outer surface of the sleeve engages an inner surface of the twist tube.

In a front wheel drive vehicle a traditional twist beam axle suffers from a short service life due to premature failures in intermediate areas between the end sections and the transitional section. A twist beam suspension is provided comprising a transverse strut (16) interconnecting longitudinal control arms (12). The transverse strut (16) may be formed from a tubular pipe. The tubular member may define a pair of tubular end sections (18), a deformed, U-shaped transitional section (20), and a pair of intermediate sections (22) between the end sections (18) and the transitional section (20). The intermediate section (22) may define a contour (28), known as a tongue. The tongue (28) enhances the flexibility in torsion and improves the stiffness in bending of the transverse strut (16). The tongue (28) may also include a concavity, to further aid in improving stiffness.

A junction connection is provided that is used to connect a torque transmitting junction component (2) to a hollow shaft (1). The junction component (2) includes a continuous recess which has a shape which corresponds to the outer cross-section of the hollow shaft (1) and which is used to receive the hollow shaft (1). The hollow shaft (1) includes a press stopper (8) in the connection area between the hollow shaft (1) and the junction component (2). The press stopper (8) forms, at least sectionally, a press fit with the wall of the hollow shaft (1). The junction connection enables the transmission of comparatively high torque during the entire service life thereof. The junction connection is also compatible with thin-walled, light-weight hollow shafts. The junction connection limits production costs, mounting and maintenance.

Process for fabricating an axle that includes a cross-member and arms which are assembled to extremities of the cross-member, wherein the process includes forming a cross-member, forming at least one arm, arranging the cross-member and the at least one arm in a fastening position, and fastening together in a rigid manner the cross-member and the at least one arm using a magneto-forming process. Wherein the fastening occurs while the cross-member and the at least one arm are in the fastening position and at least one of the cross-member and the at least one arm include at least one metallic material. This abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

The invention provides rear suspension structures and engine cradles involving tubular components. The tubular components have variable wall thickness along the length for reducing materials required. The tubular components also have mechanical properties varying along the length of the tubular components, to meet the requirements on strength and dynamic and static loads. The weight of the tubular components can be further reduced by appropriately varying the wall thickness and mechanical properties along the length of the tubular components.

The twist-beam axle (10) comprises a central cross-member (11) compliant to torsion and a pair of trailing arms (12) fixed to side end portions (11a) of the cross-member (11) for articulated connection of the axle to the vehicle body and for support of the rear wheels. Each trailing arm (12) is formed by a pair of first, transversely inner half-shells (18, 19), that is, a front half-shell and a rear half-shell, respectively, securely connected to each other and to the respective end (11a) of the cross-member (11), and by a second transversely outer half-shell (20), securely connected to the pair of first half-shells (18, 19) so as to form therewith a structure having a closed cross-section.
