Problems solved by technology

[0005] The manufacture and integration of additional shells or gaskets and webs requires corresponding production steps, which is disadvantageous in view of the production costs
Furthermore, the known multi-shell spring control sometimes has a relatively high part weight due to its reinforcing additional plate

Embodiment Construction

[0026] The figure shows a spring control arm 1 for a wheel suspension of a motor vehicle. The spring guide 1 is produced as a single-shell part from sheet metal by deformation. The spring guide 1 is a deep-drawn part. The deep-drawn part is generally produced by deep drawing. The spring link 1 has a first end section 1.1 for connection to a chassis cross member, preferably a rear axle carrier, and a second end section 1.2 for connection to a wheel carrier. A widening section 1 .3 for supporting the spring (coil spring) 2 is formed between the two end sections 1 .1 , 1 .2.

[0027] The spring guide rod 1 is made of a high-strength metal plate (preferably a steel plate). The metal plate or steel plate used to manufacture the spring guide has a yield limit greater than 650MPa.

[0028] The widened section 1.3 of the spring link 1 carrying the spring 2 is formed approximately in the shape of a groove. The side walls 1.31, 1.32 of the groove protrude upwards relative to the bo...

Abstract

The invention relates to a one-shell suspension arm (1) for a wheel suspension of a motor vehicle, the suspension arm being formed from sheet metal, comprising a first end section (1.1) for connecting to a chassis beam, preferably a rear-axle beam, a second end section (1.2) for the wheel-side connection, and a width-expanded section (1.3) for supporting a spring (2), said width-expanded section being arranged between the two end sections (1.1, 1.2) and defining a trough having flanks (1.31, 1.32) projecting upward. In order to enable optimized wheel suspension by distributing the forces and torques to spatially distanced connection or articulated-connection points while achieving a relatively low component weight and low production costs, a spiral (1.34) is formed as a spring seat in the width-expanded section of the suspension arm, and a connecting section (1.22) for connecting a shock absorber (3) is formed between the spiral (1.34) and the second end section (1.2).

Description

technical field [0001] The invention relates to a monocoque spring control formed from sheet metal for the wheel suspension of a motor vehicle, which has a first spring for connection to a chassis cross member, preferably a rear axle carrier. An end section, a second end section for connection at the wheel-side end, and a widening section for supporting the spring, which is arranged between the two end sections and has an upwardly protruding side wall Define a slot. Furthermore, the invention relates to a multi-link rear suspension for a motor vehicle comprising a rear axle carrier and a wheel carrier articulated to the rear axle carrier, wherein each The wheel carriers are articulated to the rear axle carrier via spring links. Background technique [0002] Spring guides are used to guide chassis wheels on wheel suspensions of motor vehicles. The spring link has a section for supporting a spring or a spring-damper arrangement which is supported on one side relative to the...
