Chassis Bushing for EVs
Designed to improve the dynamics, durability, noise management in BEVs with optimized design and material.
Designed to improve the dynamics, durability, noise management in BEVs with optimized design and material.
These optimized chassis bushings are tuned to handle the increased vehicle weight and higher preloads found in BEVs, while also ensuring great NVH performance. This is critical to occupant comfort and ride quality. Furthermore, BEV powertrains are substantially quieter than the ones found in ICE-powered vehicles. This presents an important challenge, since sounds previously masked by the ICE like road noise, chassis excitations, and in-cabin noises, become far more noticeable. This essentially calls for solutions with better high frequency isolation characteristics.
The chassis mounts employ optimized rubber compounds with low-hardening characteristics to better address and mitigate the frequencies encountered. The improved design allows the solution to better handle dynamic load (while driving), as well as static preload (while stationary).
About Chassis Mounts
Dozens of chassis mounts control vibrations transmitted from the road surface into the chassis of the vehicle. Chassis mounts are small but important components that improve handling and safety, and reduce unwanted vibrations.

All bushings are designed to absorb loads, caused by road surface excitations, from multiple directions. The correct stiffness and damping of the bushings are essential to maximize vehicle road holding, ride and handling. Bushings must therefore be precisely tuned in line with the whole suspension system.
Minor vibrations create an unpleasant driving experience – severe ones can result in steering disturbances and body vibrations that pose serious safety risks. To reduce vibrations, vehicles have a number of chassis mounts fitted, e.g. for the transverse control arms, subframes, suspension struts and stabilizers.
The product portfolio ranges from conventional, hydro, DualRubber chassis bushings through steering column bushings, and subframe mounts to conventional and lightweight top mounts.
