ABSTRACT:
A drive train protection device for a miniature racing vehicle is provided. The device is disposed along the drive train between the vehicle motor and the transmission. The vehicle motor rotates an engagement wheel about an axis of rotation. The engagement wheel is frictionally engaged to a shaft section by a clutch. The shaft section is engaged to the transmission. An impeller is disposed about the shaft section within an impeller housing. The impeller is free to rotate about the shaft section but the impeller housing is affixed to the shaft section and, therefore, must rotate with the shaft section. The impeller is linked to rotate with the engagement wheel. The impeller housing is filled with a viscous liquid which resists the rotation of the impeller. Thus, the drive train is protected from over-torquing by the clutch connection between the engagement wheel and the shaft section, but slippage under normal racing conditions is minimized by the resistance to impeller rotation provided by the viscous liquid.
