Description

Technical Field

[0001] The utility model relates to the field of turbochargers, in particular to a positioning component used for a turbocharger actuator. Background Art

[0002] As an important component of high-end automobile engines, the main function of a turbocharger 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 most common type of turbocharger is an exhaust gas bypass turbocharger, which uses the high-temperature combustion gas discharged by the engine to drive the turbine of the turbocharger, thereby driving the compressor of the turbocharger 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 turbocharger 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] like Figure 1-2 As shown, after the connecting rod of the common execution structure is connected, it is limited by a positioning assembly. In order to compensate for the assembly clearance during the connecting rod matching process and reduce the noise of the connecting rod during movement, a wave spring is added between the pull rod and the rocker arm. This structure is complex to assemble and has a high production cost. Utility Model Content
