Permanent-Magnet-Type-Retarder in Commercial Vehicles 922455
Recently engin output and vehicle speed are much improved and there received much requests for better brake system with high performance and safety. In order to meet these reguests research work was initiated to develop new retavder system as auxiliary brake, and new compact & light weight retarder without requiring electricity consumption was successfully developed by using very strong parmanent magnet of Nd-Fe-B base for the first time in the world.
This new retarder was marketed in the last January for the heavy duty truck followed medium duty tyuck in this April. This new retarder well matched with market needs has been highly commented upon beyond engineer expectation, and it is believed that this new system will be popularized very rapidly in Japan.
