LEMFÖRDER Control Arms For Accurate Wheel Guidance
In order to ensure safe vehicle handling for the driver, even in the event of extreme road conditions, it is important that the movement of the wheels is transferred quickly and precisely. For this purpose, intelligently designed control arms with joints are used within the wheel suspension.

LEMFÖRDER provides many different, vehicle-specific types of control arms, also for complex axle constructions: from guide rods, track rods and tension struts via control arms through to suspension ball joints or supporting joints. In the case of independent suspensions, the wheel carrier can be connected to the vehicle body with up to five control arms. Depending on the customer requirement, the components are either set up for comfortable or dynamic driving properties. Depending on the construction type, either 2-point links, 3-point links or, on rare occasions, 4-point links are used. Besides steel control arms, LEMFÖRDER also develops and manufactures light, premium aluminum control arms for cars and vans.
The control arms undertake the task of wheel guidance and frequently also transfer spring, damper and stabilizer forces.

Dynamic or comfortable? When it comes to the independent suspension, it depends, among other things, on the design of the control arms which connect the vehicle body with the wheel and its tires.
LEMFÖRDER transverse control arms are precisely tailored to the individual requirements and driving properties of a vehicle. Furthermore, alternative materials such as aluminum, which make the wheel suspension lighter overall, are used in the manufacturing process. Lightweight design is one of the key technologies when it comes to reducing the energy consumption of vehicles.

Depending on the function that a control arm assumes, either a guiding control arm or a supporting control arm is used for wheel guidance. A guiding control arm absorbs braking, driving and lateral forces. A supporting control arm supports the vehicle weight additionally. Moreover, it takes over the suspension and damping functions in the body and is designed to be more stable. Supporting control arms are often used by automotive manufacturers in the lower level of double wishbone axles and multilink rear suspensions.

LEMFÖRDER SMiCA sheet metal control arm without rivets and screws.
Control arms are subjected to severe forces and must therefore satisfy high requirements: buckling resistance, bending strength and durability. At the same time, a low weight is desired within the context of modern, automotive lightweight construction.
A ZF lightweight solution that is already ready for production is the SMiCA control arm (Sheet Metal integrated Control Arm). The control arm requires no rivets or screw connections and is therefore up to 23 percent lighter than conventional sheet metal control arms. Furthermore, it requires less installation space and allows more design freedom when designing the chassis.

LEMFÖRDER ball joint
The design core: the ball joint
Ball joints are used in control arms, tie rods and stabilizer links, for instance. A ball joint consists of a supporting joint and ball stud and is free-moving in three directions. Traction forces, compressive forces and radial forces are transferred in these three directions with hardly any losses at all. Low losses occur as a result of friction. Therefore, LEMFÖRDER uses premium materials for the ball and shell and consequently achieves:
Low deformability
Excellent glide characteristics
Outstanding damping
The exact designation of the ball joints is derived from the transferred direction of force: Angle joints transfer radial forces, axial joints transfer axial forces.
