Description

Technical Field

[0001] The invention relates to the technical field of turbochargers, and in particular to a rotary 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. However, the locating ring needs to be opened manually during installation, which makes installation difficult.

[0025] like Figure 3 As shown, the rotating frame 1 includes a rotating ring 1-1 and a first sliding groove 1-2, and the first sliding groove 1-2 is transversely opened on the rotating ring 1-1; like Figure 4 As shown, the fixed seat 2 includes a fixed ring 2-1 and a second slide groove 2-4, the rotating ring 1-1 is just nested outside the fixed ring 2-1, and the second slide groove 2-4 is transversely opened on the fixed ring 2-1; like Figure 5 As shown, the first pull rod 3 includes a first rod body 3-1, a first working shaft 3-4, and a first sliding shaft 3-2. The middle part of the first rod body 3-1 is rotatably connected to the fixed ring 2-1. The first sliding shaft 3-2 and the first working shaft 3-4 are respectively vertically connected to the two ends of the first rod body 3-1. The first sliding shaft 3-2 is slidably connected to the first sliding groove 1-2. The first working shaft 3-4 passes through the central through hole of the fixed ring 2-1. like Figure 6 As shown, the second pull rod 4 includes a second rod body 4-1, a second working shaft 4-4, and a second sliding shaft 4-3. One end of the second rod body 4-1 is rotatably connected to the rotating ring 1-1, and the second sliding shaft 4-3 and the second working shaft 4-4 are vertically connected to the middle part and the other end of the second rod body 4-1 respectively.
