Abstract
The invention discloses a linkage device for automatically controlling the oil inlet flow and the oil return flow of a silicone oil clutch. At least two opening oil through grooves are formed in the end face of an attraction disc. Valve bases are arranged inside the opening oil through grooves. The valve bases are in elastic connection with one end of a spring piece connected to the end face of the attraction disc. A connecting hole is formed in the other end of the spring piece. When the linkage device works, due to the electromagnetic attraction, dual elastic pressures of the connection between the attraction disc and a component through the spring piece and the connection between the valve bases and the attraction disc through the spring piece are overcome at the same time, synchronous variable-distance attraction and displacement pulling are carried out on the attraction disc and the valve bases, the variable flow at an opening gap opened by the linkage between the attraction disc and one end face of each valve base in an oil inlet hole is increased, and meanwhile the variable flow at an opening gap opened by the other end face, opposite to an oil return hole, of each valve base is decreased.
