turbocharger regulator lever

Abstract

The invention belongs to the technical field of turbochargers, and relates to a turbocharger regulator rod geometric feature and a corresponding assembly fixture, specifically, a turbocharger regulator rod, including a regulator rod body, and the regulator rod body is provided with Knurled structure and threaded part, the tail rod is threadedly connected to the threaded part, the first clamp is nested on the tail fin of the tail rod, the clamping end of the second clamp is clamped on the knurled structure, the connecting rod of the first clamp is set in the connection hole of the second fixture. While retaining the advantages of the existing adjustable tail rod, the product of the present invention effectively solves the problem of the follow-up rotation of the adjuster rod in the process of fixing the tail rod with a nut; through the cooperation of the knurling of the rod body and the assembly fixture, the adjuster tail rod is fixed at the same time And the shaft, to prevent relative rotation, thereby reducing the setting pressure fluctuations and improving the pass rate of subsequent processes; 360-degree knurling, not limited by the angle of the adjuster; fixed knurling position, easy to process; adjustable clamp height, strong versatility.

Description

technical field [0001] The invention belongs to the technical field of turbochargers, and relates to a geometric feature of a turbocharger regulator rod and a corresponding assembly fixture, in particular to a turbocharger regulator rod. Background technique [0002] The regulator is an important component in controlling the opening of the bypass valve in the turbocharger. Opening the bypass valve too early will cause unnecessary loss of efficiency, and opening it too late will fail to effectively reduce the turbine speed to prevent overheating. Therefore, it is necessary to accurately set the valve opening pressure during the installation of the regulator. [0003] Existing regulators can be divided into tail rod fixed type and position adjustable type according to different tail rod designs. Among them, the adjustable tail rod design can meet higher assembly accuracy and fit margin, but there are also shortcomings. The adjustable tail rod uses a nut to fix the position ...

Problems solved by technology

Once the follow-up occurs, the regulator film connected to the shaft rotates under its own restoring force, causing the following consequences: 1. The spring preload of the regulator changes so that the opening pressure of the bypass valve changes; 2. The tail rod of the regulator is caused by Angle deviation caused by the swivel causes the joint between the regulator and the turbocharger housing to stick, and when the sticking is serious, it will lead to assembly rework

[0004] To sum up, if we want to prevent the risk of the adjuster rod from rotating while retaining the advantages of the adjustable tail rod, we need to solve the problem that the existing assembly process can only fix the tail rod
