TOKYO: Hitachi Astemo Co., Ltd. today announced that its damping force adjustment absorber co-developed with Aisin Corporation is superior to conventional types and has been adopted by Toyota for the new Land Cruiser launched in June.

It said the absorber improves control for the Land Cruiser.

While shock absorbers typically have a single mechanism to adjust damping force during extension and compression, the Hitachi suspension is able to adjust the damping force using separate mechanisms enabling more precise control, resulting in a higher level of maneuverability and a more comfortable driving experience, the company said.

By incorporating the damping force control valve in the shock absorber, instead of on the outside where it is conventionally installed, the structure can be simplified, it added.

Volume has been reduced by about 20% and weight by 30% compared to Hitachi's conventional shocks, making it easier to mount on the vehicle.
