HEAT SHIELD FOR AN EXHAUST GAS TURBOCHARGER AND ARRANGEMENT OF A HEAT SHIELD BETWEEN TWO HOUSING PARTS OF AN EXHAUST GAS TURBOCHARGER

摘要

In a heat shield for an exhaust gas turbocharger, by means of which at least a first area of the exhaust gas turbocharger is to be shielded against a second area in a heat insulating manner wherein the heat shield comprises at least one fastening structure by which the heat shield is attached to one of the housing parts of the exhaust gas turbocharger, the fastening structure is in the form of locking elements for interlocking the heat shield with the respective housing part. The invention also resides in an arrangement of a heat shield between two housing parts of an exhaust gas turbocharger in such a way that it is firmly attached to one housing part without contacting the other housing part.

主权项

1. A heat shield for an exhaust gas turbocharger having a bearing housing part (12) attached to a turbine housing part (18) of an exhaust gas turbocharger (10), the heat shield (22) being arranged between the bearing housing part (12) and the turbine housing part (16) so as to limit heat transfer between the turbine housing part (18) and the bearing housing part (12) and comprising fastening means (24, 34, 45), for attaching the heat shield (22) to one of the housing parts (12, 18) of the exhaust gas turbocharger (10), the fastening means (24, 34, 45) being in the form of locking elements (24, 34, 45) for interlocking the heat shield (22) with the housing part (12, 18) to which the heat shield is attached without being in contact with the other housing part.
