Embodiment Construction

[0019] It should be noted that the features mentioned separately in the following description can be combined in any technically meaningful way and form further embodiments of the invention. The following description additionally describes and details features of the invention.

[0020] According to the invention, the transverse arms have a U- or V-shaped profile or cross-section at their respective ends, and each longitudinal arm has a corresponding U- or V-shaped recess to accommodate the U- or V-shaped profile. During assembly, ie during the adhesive bonding, the glue-applied end regions of the transverse arms are introduced into corresponding recesses of the longitudinal arms up to stops provided on the longitudinal arms or on the ends of the transverse arms. It is of course also possible to provide glue on the inner surface of the longitudinal arm recess instead of or in addition to the end area of ​​the longitudinal arm. To simplify the joining process, an inwardly roun...

Abstract

The axle has a set of linked trailing arms swingable around a pivotal axis and arranged at a vehicle body transverse to a direction of travel. A torsion-soft transverse strut is arranged between the trailing arms parallel to the pivotal axis. Multiple ends of the transverse strut are connected with the trailing arms by sticking. A U or V-shaped recess of the trailing arms is provided corresponding to a U or V-shaped profile at the ends of the transverse strut.

Description

technical field [0001] The invention relates to a semi-independent axle of a motor vehicle having two wheel-carrying longitudinal and transverse arms pivotally connected to the vehicle body. Background technique [0002] In the motor vehicle manufacturing industry, there is a pervasive effort to achieve maximum economy and efficiency when producing motor vehicle components. These requirements also apply to semi-independent axles that combine the advantages of low volumetric weight and ease of manufacture with good dynamic characteristics. This semi-independent axle essentially consists of two longitudinal arms connected by a transverse arm that acts as a torsion bar. Various joining methods are known to connect the longitudinal arms to the transverse arms, the most common being welding. [0003] Typically, semi-independent axles are manufactured from semi-formed steel components. However, as part of the effort to achieve lightweight construction, aluminum has proven to be...
