Problems solved by technology

[0009] On the other hand, there is a surplus of compressor power in the various operating phases in which, also due to the inertia of the turbocharger, the combustion engine's Power drops rapidly, and this can lead to "compressor surge"
This state in particular requires an increased mechanical load on the components of the turbocharger and compressor and can even lead to damage to the corresponding components

Embodiment Construction

[0029]Throughout the drawings, the same parts as in terms of function and marking are represented by the same reference symbols. When describing the objects described in the objects, "top", "above" or "upper" and "bottom", "lower" or "lower", "top", "above" and "The upper side" is referred to as the region of the joint ball 81 in the case of the transport element 70 and the component body 73, and in the case where the joint ball 81 refers to the region of the club. "Bottom", "below" and "underside" are used to represent a correspondingly opposite area.

Abstract

The invention relates to a turbocharger (1) for an internal combustion engine which comprises an actuation device (50) for matching its operating behaviour to the operating behaviour of the internal combustion engine, an actuator (60), and a transmission element (70), which is coupled to the actuator (60) on the one hand and to the actuation device (50) on the other hand. The transmission element (70) comprises a one-part component body (73), which extends from a first coupling point (62) to a second coupling point (52) along a longitudinal axis (75) and has a coupling element (71, 72) in each of its end regions for coupling to the actuator (60) and to the actuation device (50), the coupling elements (71, 72) each being formed as an integral part of the component body (73) in the form of a ball receptacle (82) of a ball joint connection (80) in the component body (73).

Description

Technical field[0001]The present invention relates to a turbocharger for combustion engine (especially for motor vehicles), wherein the turbocharger has a regulating device for making operation behavior to match the operation behavior of the combustion engine, said The device is actuated by means of an actuating actuator.Background technique[0002]In order to reduce fuel consumption and pollutant emissions, the same or even increased power of combustion engines (especially internal combustion engines in motor vehicles), more and more cases are small volume engine concepts (so-called miniaturization concept) As a starting point, the small volume engine concept is equipped with a turbocharger for the purpose of increasing power.[0003]The operation principle of the turbocharger is to increase the pressure in the intake of the combustion engine by the energy included in the exhaust stream, and in this manner, it can cause better inflation to the combustion chamber with atmospheric oxygen...
