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

Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0016] Such as figure 1 , figure 2 As shown, it includes an adjuster rod body 1, a knurled structure 2, a tail rod 3, a first clamp 4, a connecting rod 4.1, a second clamp 5, a handle 5.1, a jaw 5.2, and the like.

[0017] Such as figure 1 , 2 As shown, a turbocharger regulator rod of the present invention includes a regulator rod body 1, the regulator rod body 1 is provided with an anti-rotation structure part and a threaded part, and the tail rod 3 is threaded on the threaded part. The clamp 4 is nested on the fin of the tail rod 3 , the clamping end of the second clamp 5 is clamped on the knurled structure 2 , and the connecting rod 4 .

[0018] A knurl structure 2 is provided on the circumferential surface of the anti-rotation structure part.

[0019] The knurl structures 2 are evenly distributed on the circumferential surface of the adjuster rod body...

Abstract

The invention belongs to the technical field of turbochargers and relates to turbocharger governor lever geometrical characteristics and corresponding assembly fixtures, in particular to a governor lever of a turbocharger. The governor lever includes a governor lever body. A knurled structure and a threaded part are arranged on the governor lever body. A tail rod is in threaded connection with the threaded part. A first fixture is nested in a tail wing of the tail rod. The clamping end of a second fixture is arranged on the knurled structure in a clamping mode. A connecting rod of the first fixture is arranged in a connecting hole of the second fixture. The governor lever can effectively solve the problem that a governor lever rotates along with a tail rod in the process of fixing the tail rod with a nut while the advantages of an existing adjustable tail rod are reserved; the tail rod of a governor and the governor lever body are fixed at the same time through cooperation between knurls of the governor lever body and the assembly fixtures, so relative rotation is prevented, design pressure fluctuation is reduced, and the follow-up process pass rate is increased; 360-degree knurling is not limited by the angle of the governor; knurling positions are fixed, so machining is convenient; the height of each fixture is adjustable, and therefore the governor lever is high in universality.

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 ...
