ABSTRACT:
A steering damper particularly for a bicycle which is integrated into the bicycle. The damper includes a housing closed at the top by a cap from which sidewalls extend and at the bottom. The housing contains a damping medium. Within the housing thee is a dam connected to the housing and a single vane connected to a shaft which passes through the housing. There is an opening in the shaft which communicates with the vane to circulate the medium during the damping when the bicycle departs from the path in which it is being directed and during the suppression of the damping when the bicycle returns to the path along which it is directed. The effective cross-section of the opening in the shaft is of sufficient magnitude to permit unrestricted flow of the medium. The housing and dam are supported within the steer-tube by the clamp from the steer-stem and are connected to the clamp by a tapered bearing rotatably with the steer-tube as the steer-tube is rotatable by the handlebars. The vane and shaft are not rotatable. Rotation of the dam on departure of the bicycle from its directed path pressurizes the medium between the dam and vane by flow through the shaft producing the damping and return of the bicycle produces flow of the medium through the vane and shaft suppressing the damping.
