Custom-made engine mounts for Stromer
According to experts, there will already be 150 million electric cars on the roads worldwide by 2030. This also requires the development of new engine mounts, as electric vehicles vibrate differently than combustion engines.

The global increase in electromobility also has far-reaching effects on the supply industry: The electrified mobility of tomorrow brings with it new requirements in various areas. An example: engine mounting.
Sure: There are clear differences between electric and combustion engines. This affects the components that are close to the drive and engine. “The requirements for engine mounts, for example, are completely different in electric cars,” emphasizes Scott Bykowski, head of research and development for bearing elements at Continental. Despite the overall quieter background noise, electric motors still produce excitations in the high-frequency range. Higher torques and lower temperature conditions characterize the electric motor compared to the combustion engine. The resulting phenomena can be felt and heard and are not always pleasant for people. In addition, the classic engine noises of the combustion engine, which cover up rolling and wind noises, for example, are missing. “These factors have an impact on the development of rubber component mixtures, but also on engine mounts in general,” says Bykowski.
That's why Continental has developed special elastomer mixtures for electric vehicles. They absorb vibrations in the high-frequency range and are also light. The lower weight reduces energy consumption in the electric vehicle and increases the range. Continental also adapts other bearing elements such as battery bearings for buses or air compressor bearings in the driver's cab of trucks to the requirements of e-mobility.
