Description

Technical Field

[0001] The invention relates to the technical field of turbochargers, and in particular to a grip-type positioning ring installation mechanism. Background Art

[0002] As an important component of high-end automobile engines, the main function of turbochargers is to increase the intake density of automobile engines, make the fuel combustion of gasoline engines more complete, and increase the driving force of the engine. The common type of supercharger is the exhaust gas bypass supercharger, which uses the high-temperature combustion gas exhausted by the engine to drive the turbine of the supercharger, thereby driving the compressor of the supercharger to work. Since the amount of exhaust gas discharged by automobile engines at different speeds is different, the required intake volume is also different. This type of supercharger is generally equipped with an actuator structure in the volute flow channel to control the exhaust gas bypass valve, which can control the amount of exhaust gas entering the turbine.

[0003] After the connecting rod of the common execution structure is connected, it is limited by a locating ring. In order to compensate for the assembly gap during the connecting rod matching process and reduce the noise of the connecting rod during movement, a locating ring is added between the pull rod and the rocker arm. The locating ring is a simple steel wire shape with elastic tension. It needs to be opened manually during installation, which makes installation difficult.

[0004] Therefore, a grip-and-press type positioning ring installation mechanism is developed to solve the above problems. Summary of the invention
