Problems solved by technology

[0003] The wastegate supercharger in the prior art (hereinafter referred to as WG bypass supercharger) needs to open the bypass drive structure of the bypass supercharger when the engine is running at high speed, and the bypass drive mechanism needs to be opened when the vehicle stops suddenly. The structure needs to be closed. At this time, vibration will be generated in the bypass crank structure, and the cover plate of the bypass mechanism hits the shell of the turbo bypass supercharger, thereby producing an obvious seating knocking sound, which affects the customer's NVH (Noise, Vibration, Harshness) feeling

Abstract

The invention discloses an actuator connecting mechanism, a bypass supercharger and a vehicle, small-amplitude vibration generated due to the influence of exhaust pulses is effectively reduced through a connecting frame, the amplitude of knocking a turbine bypass supercharger shell by a bypass mechanism cover plate is improved, and therefore knocking sound is reduced. The actuator connecting mechanism comprises a linkage crank, a first actuating rod, a second actuating rod and a connecting frame; wherein the linkage crank is used for being connected with a deflation valve of the bypass supercharger, the second execution rod is used for being connected with an actuator, one end of the first execution rod is connected with the linkage crank, the other end of the first execution rod is connected with the second actuating rod through the connecting frame, and the connecting frame is provided with an open bent part; and the connecting frame is used for connecting the connecting parts of the first execution rod and the second execution rod and located on the two sides of the opening of the bent part. Pulse generated by pressure is resisted through the connecting frame, vibration of the WG system is reduced, and the technical effect of reducing seating sound and knocking sound is achieved.

Description

technical field [0001] The invention relates to the technical field of turbocharging, in particular to an actuator connection mechanism, a bypass supercharger and a vehicle. Background technique [0002] In recent years, due to the sharp increase in the number of automobiles, the huge fuel consumption and exhaust pollution of automobiles have become urgent problems to be solved. Turbocharging technology can not only reduce the emission of pollutants, but also improve engine power and save energy, so it is widely used in automobile engines. [0003] The wastegate supercharger in the prior art (hereinafter referred to as WG bypass supercharger) needs to open the bypass drive structure of the bypass supercharger when the engine is running at high speed, and the bypass drive mechanism needs to be opened when the vehicle stops suddenly. The structure needs to be closed. At this time, vibration will be generated in the bypass crank structure, and the cover plate of the bypass mec...
