As shown in fig. 1 and fig. 2, the exhaust gas bypass valve assembly structurally includes a rocker arm 1, a valve cover 2, a positioning element, an elastic element and a sliding element, wherein a valve cover connection hole 100 is formed at one end of the rocker arm 1, the valve cover 2 includes a cover body 21 and a connection shaft body 22 fixedly connected with the cover body 21 and penetrating through the valve cover connection hole 100, the positioning element is fixedly connected to one end of the connection shaft body 22 penetrating through the valve cover connection hole 100, the elastic element and the sliding element are overlapped between the positioning element and the end portion of the rocker arm 1 having the valve cover connection hole 100, and the elastic element and the sliding element are both sleeved on the connection shaft body 22.
Specifically, when the rocker arm 1 is mounted in a bushing on a turbocharger volute during use, the tail end of the rocker arm 1, namely the other end of the rocker arm 1 opposite to one end with the valve cover connecting hole 100, is connected with an electric control actuator, so that the rocker arm 1 is driven to rotate by the electric control actuator, the valve cover 2 is driven to rotate by the rotation of the rocker arm 1, and the adjustment of the exhaust gas bypass flux is realized through the opening degree of the upper cover body 21 of the valve cover 2.
In this embodiment, the inner diameter of the valve cover connecting hole 100 is slightly larger than the outer diameter of the connecting shaft body 22 in design, so that the outer peripheral wall of the connecting shaft body 22 and the inner peripheral wall of the valve cover connecting hole 100 are in clearance fit, and the valve cover 2 can swing to a certain extent relative to the rocker arm 1 through the clearance fit, thereby being beneficial to ensuring the sealing performance of the valve cover 2. In addition, as a preferred implementation structure of the present embodiment, the positioning element may be a positioning pad 3 fixedly connected to the end of the connecting shaft body 22, and the elastic element and the sliding element may be an elastic pad 4 and a sliding pad 5 stacked between the positioning pad 3 and the rocker arm 1.
The positioning gasket 3 can be fixedly connected with the connecting shaft body 22 in a welding, riveting or screwing mode, the elastic gasket 4 can adopt an existing common disc-shaped spring piece, namely the disc-shaped spring piece with the same circumferential section along the elastic gasket, the common disc-shaped spring piece is simple in manufacturing process, low in cost, not easy to break and lose efficacy and good in reliability. Corresponding to the elastic gasket 4, an annular structure protruding toward one side of the elastic gasket 4 is also arranged at the bottom of the positioning gasket 3, and the annular structure abuts against the elastic gasket 4, so that after the positioning gasket 3 is fixed on the connecting shaft body 22, an acting force is applied to the elastic gasket 4, and the elastic gasket 4 is compressed by a preloading force to generate a pretightening force capable of acting on the sliding gasket 5 and the cover body 22.

In addition, in order to reduce abrasion and noise and ensure better sealing performance of the bypass valve, in the embodiment, the elastic gasket 4 and the sliding gasket 5, and the sliding gasket 5 and the rocker arm 1 are also configured to have relative sliding between each other, that is, when the valve cover 2 swings relative to the rocker arm 1, the sliding gasket 5 can slide relative to the rocker arm 1, and the elastic gasket 4 can also slide relative to the sliding gasket 5, so that the matching between the elastic gasket 4 and the positioning gasket 3 is almost unchanged and the pretightening force of the elastic gasket 4 is almost unchanged through the relative sliding between the elastic gasket 4, the sliding gasket 5 and the rocker arm 1, and the effect of ensuring the sealing performance of the bypass valve can be achieved.
In detail, as shown in fig. 3, for the relative sliding between the sliding pad 5 and the rocker arm 1, in the present embodiment, the rocker arm 1 and the sliding pad 5 are in contact with each other through the rocker arm first contact surface 101 and the sliding pad first contact surface 501 respectively formed on the rocker arm 1 and the sliding pad 1, and the rocker arm first contact surface 101 and the sliding pad first contact surface 501 are also in linear contact with each other by adopting the fit of the arc surface and the conical surface shown in the figure.
