The invention relates to a connection system for connecting a damper unit of a vehicle inside a wheel suspension of the vehicle, the connection system having: an upper attachment region for attaching the damping unit, at least part of said region surrounding a receiving area for the damping unit and the receiving area extending around a first axis acting as the damping axis of the damping unit; a lower attachment region for coupling to the wheel-side portion of the wheel suspension, said lower attachment region having, in particular, two mutually spaced lower sections with an attachment area therebetween and an intermediate region which connects the upper attachment region to the lower attachment region. The main extension of the intermediate region corresponds to the direction of the first axis and the intermediate region allows the passage of a drive shaft of the vehicle. The connection system is made of an extruded part, the extrusion direction of which is the direction in which the extruded material extends, said material thus forming the intermediate region of the connection system. The invention also relates to a connection system comprising a clamping mechanism.

An efficient method for producing spring strut forks for motor vehicles is presented. In each case two spring strut forks are produced from a metallic extruded profile as a starting product. The extruded profile has a central, middle main chamber and four longitudinal chambers which are arranged offset with respect to one another over the circumference of the main chamber. Wall portions of the main chamber which are situated between the longitudinal chambers are removed, and the extruded profile is severed into two semifinished parts. Each semifinished part has one cylinder portion and two oppositely situated arm portions which project relative to the cylinder portions. The semifinished parts are subsequently mechanically machined, and one spring strut fork is produced from each semifinished part.

The disclosure relates to a motor vehicle control arm, like a wishbone, having an integral main body configured in a materially integral manner. A first bearing receptacle is connected to the main body. The main body has a first end portion having a second bearing receptacle, and a second end portion having a third bearing receptacle. The main body comprises a central portion. Said central portion connects the first and the second end portion. The central portion is configured as a cavity profile. The second and the third bearing receptacle are configured integrally and in a materially integral manner from the main body.

A control arm and a method of manufacturing thereof is disclosed. The control arm is made of an aluminum extrusion profile with a first end section, a second end section, and a middle section, which connects the first and second end sections. The control arm includes a base, two side walls, which are angled substantially perpendicular therefrom and which are spaced apart from one another on the longitudinal side, with a height H, and flanges, which are angled substantially perpendicular from the side walls at their free end. The first end section includes a first connecting region, the second end section includes a second connecting region, and the middle section includes at least one third connecting region.

A method for producing a joining connection between a joint housing and at least one connection component including: providing a blank for the fabrication of the joint housing, and providing a connection component with a joint receptacle inserting the blank into the joint receptacle of the connection component and producing the joint housing through forming by cold extrusion of the inserted blank. An undercut positive-engagement joining connection is generated between the joint housing and the connection component during the cold extrusion process through transverse extrusion and/or upsetting. A chassis component has a structural component part with at least one joint receptacle formed as orifice and a joint housing for a joint device, which joint housing is inserted into this joint receptacle and fastened to the structural component part.

A method for producing motor vehicle controls from extruded profiles and a motor vehicle control. A length section of an extruded profile strand is provided and this is either processed by cutting technology and divided into several extrusion profiles or is first divided into several extruded profiles and they are then processed via shear cutting. By means of a mechanical processing of the extrusion profiles, the motor vehicle controls are formed. The length section has a double T-shaped cross-section with a brace and two belts aligned perpendicular to the brace, wherein the end-side of the belts are connected to flanges. During manufacturing, a motor vehicle control is produced with a steering element, which comprises a middle part and two side arms. In the middle part as well as in the side arms, bearing housings are configured.

The present disclosure relates to a chassis component having a base body, wherein the base body has an opening for passing through a fastening means and two guide elements for guiding an eccentric element are arranged on opposite sides of the opening, wherein the guide elements are formed in one piece and using the same material of the base body of the chassis component by mechanical processing and each have a back side and a contact side facing the opening, wherein the contact side is formed orthogonally to the base body. According to the present disclosure, an outer transition region with a radius is formed between the respective contact sides and the base body. The present disclosure further relates to a method for producing a chassis component.

A damper assembly includes a tubular member including a sidewall and a shoulder. The damper assembly includes a rod and a piston coupled to the rod. A secondary piston has a second contact surface, an opposing second surface, an inner cylindrical face defining a central aperture that receives the rod, and an outer cylindrical face. The opposing second surface includes one or more surface grooves, extending between the inner cylindrical face and the outer cylindrical face along the opposing second surface, and one or more bypass orifices disposed about the body member. The bypass orifices extend along the inner cylindrical face between the second contact surface and the opposing second surface. The secondary piston defines a channel extending between the inner cylindrical face and an outer periphery of the body member. The channel and bypass orifices form a fluid flow path when the piston contacts the secondary piston.

A spring assembly for a non-rail wheeled or tracked vehicle is provided. The spring assembly includes a piston, and a sleeve with variable thickness. The sleeve is made from an unreinforced synthetic elastomeric material and being free of reinforcing fibers. The sleeve is coupled with a plurality of end components and defines a deformable pressure vessel, and the deformable pressure vessel supplies a support force.

A control arm and a method of manufacturing thereof is disclosed. The control arm is made of an aluminum extrusion profile with a first end section, a second end section, and a middle section, which connects the first and second end sections. The control arm includes a base, two side walls, which are angled substantially perpendicular therefrom and which are spaced apart from one another on the longitudinal side, with a height H, and flanges, which are angled substantially perpendicular from the side walls at their free end. The first end section includes a first connecting region, the second end section includes a second connecting region, and the middle section includes at least one third connecting region.
