Due to their battery pack Battery Electrical Vehicles (BEVs) tend to be heavier than petrol cars. Steering and suspension parts for this type of car are therefore subjected to more stress and thus require an optimized design. Besides, the faster accelleration of BEVs results in higher torque what means that ball joints in these cars need to be stronger for a higher security of the driver. On top, BEVs produce less noise and vibration. That is why Sidem’s silent blocks are reengineered to optimize the driving comfort.
“At present (May 2023), Sidem has 960 unique references for 32 European and Asian BEV brands, in total 147 private and light commercial models. Which means a relevant coverage of 83,66%, the highest score within the aftermarket.”
Being the expert for steering and suspension car parts, Sidem has an extensive range of references, available from stock. All engineered and produced in Europe.
Because ball joints in BEVs are subject to extra torque, they are designed and built to handle this additional impact. Sidem ball pins for example are made of chromium steel (42CrMo4V). The hardness of this material ensures maximum strength of the part and prevents it from breaking at extreme impact.
In addition to the material from which the ball pin is made, the ball pin diameter is an important factor to secure it to withstand the heavy load and the higher torque. That is why the diameter of ball pins for BEVs are bigger than the ones for their petrol counterparts.
With the shift towards low emission zones and the EU’s demand for CO2 neutrality by 2035, the automotive industry is rapidly moving towards electric vehicles. Therefore, Sidem has developed an extensive range of specialized parts for Battery Electrical Vehicles (BEVs).
Since electrical cars produce less noise and vibration compared to cars with internal combustion engines, the suspension system in a BEV is designed with a greater focus on minimizing road noise and vibrations transmitted to the cabin.
In Sidem’s BEV track control arm the ball joint is directly incorporated in the aluminum housing.
