Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to a transition rocker arm plate protective structure. Background Technology

[0002] With users' increasing demands for engine power and economy, turbocharging technology is being applied to engines for various purposes. As engine technology develops, turbocharger housings are usually designed with an exhaust gas bypass valve to remove excess exhaust gas, control turbocharger speed and pressure inside the turbine housing, and ensure smooth turbocharger operation. The transition rocker arm is the switch used to control the opening and closing of the exhaust gas bypass valve assembly.

[0003] Because the transition rocker arm plate is exposed outside the vortex casing, foreign objects falling and impacting the transition rocker arm plate can cause it to deform, disrupting the original force balance and motion trajectory. This can lead to incomplete opening and closing of the damper, or even more serious mechanical failures. At the same time, high external temperatures can also cause thermal deformation of the transition rocker arm plate, altering its mechanical properties and preventing it from maintaining its original shape under stress. This can affect transmission accuracy and cause the damper to fail to open and close properly.

[0004] Therefore, there is an urgent need for a transition rocker arm plate protection structure to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to propose a protective structure for the transition rocker arm plate, which can prevent external foreign objects from falling and impacting the transition rocker arm plate, avoid deformation of the transition rocker arm plate, and at the same time prevent thermal deformation of the transition rocker arm plate.

[0029] Specifically, the protective cover 2 is mounted on the transition rocker arm plate 1. One end of each of the several fixing members 4 passes through the protective cover 2 and is fixedly connected to the transition rocker arm plate 1. The other end of each of the fixing members 4 presses the protective cover 2 against the transition rocker arm plate 1. The heat insulation cover 3 is connected to the protective cover 2 at an angle and is located between the transition rocker arm plate 1 and the air inlet of the vortex shell 5. Compared with the prior art, this transition rocker arm plate protection structure, by setting the protective cover 2 on the transition rocker arm plate 1 and fixing the protective cover 2 to the transition rocker arm plate 1 with the fixing members 4, can prevent external foreign objects from falling and impacting the transition rocker arm plate 1, thus avoiding deformation of the transition rocker arm plate 1. At the same time, by setting the heat insulation cover 3, this transition rocker arm plate protection structure can isolate the heat discharged from the air inlet of the vortex shell 5, thus preventing thermal deformation of the transition rocker arm plate 1.

[0030] Optionally, the protective cover 2 is provided with a plurality of through holes 21, each corresponding to a plurality of fixing members 4. One end of the fixing member 4 passes through the through hole 21 and is fixedly connected to the transition rocker arm plate 1, while the other end of the fixing member 4 abuts against the end face of the protective cover 2.
