Abstract

The invention relates to the technical field of mechanical design and relates to a triaxial synchronous type variable exhaust branch reducing rate system comprising a volumetric cavity, an elastic member, a rotor, a partition, rotary shafts, rotary plates and a chain. The longitudinal section of the volumetric cavity is circular. The longitudinal section of the rotor is arc-shaped. One end of a third connecting shaft passes through the volumetric cavity and is embedded on the side wall of the volumetric cavity, and one end of the first rotary shaft passes through a first exhaust branch and is embedded on the side wall of the first exhaust branch. When the pressure of an intake pipe of an engine is high, the rotor drives the rotary plates to rotate anticlockwise, outlet area of the exhaust branch is large, and pumping loss of the engine is low; when the pressure of the intake pipe of the engine is low, the rotor drives the rotary plates to rotate clockwise, outlet area of the exhaust pipe is small, pulse energy can be fully utilized, and turbine inlet available energy is high. The triaxial synchronous type variable exhaust branch reducing rate system is reasonable in design, simple in structure, and applicable to a turbocharging system with one turbine inlet and a side turbine.
