Embodiment Construction

[0029] The same reference signs are always applied to the same elements in the different drawings.

[0030]The development according to the invention of the shielding with the additional function of being inductively heatable by the heating system is basically not limited to specific applications. The integration of this type of heating in the shield can take place in different forms. For example, the heating can be integrated into a shield for so-called direct insulation. There, the elements are actively fed electrically or are electromagnetically coupled to the drive train or its components for heating. As a result, exhaust gas purification, for example based on the use of catalytic converters, can take effect earlier, and correspondingly emissions and fuel consumption in gasoline and diesel engines can be reduced, thereby also reducing carbon dioxide emissions, for example from motor vehicles. Furthermore, it is also conceivable to integrate the heating system in the mult...

Abstract

The present invention relates to a device (1) for thermally and / or acoustically shielding a drivetrain or part thereof, wherein the device (1) comprises at least one layer of thermally loadable fibermaterial with high thermal insulation properties and is designed to be laid on the exterior of a certain part of the drivetrain or to enclose the part. In order to solve the problem of an excessivelylow temperature of the covered part by providing a device of the stated type which can additionally be integrated cost-effectively into an existing system, it is proposed that at least one element (4)for inductively heating a drivetrain or part thereof is integrated or embedded in the device (1) for thermal and / or acoustic shielding.

Description

technical field [0001] The invention relates to a device for the thermal and / or acoustic shielding of a drive train or its component parts and its use. Background technique [0002] Several different concepts are known from the prior art for the construction of devices of this type, by means of which the drive train or its component parts are thermally and / or acoustically shielded from the adjacent surroundings. For this purpose, devices are known as shields, which are placed externally on certain components of the drive train or closed around them. By means of known devices, correspondingly covered components of the drive train can be shielded from the adjacent environment and thus also be protected within limits against cooling caused by external influences. In contrast, the known devices do not provide protection against excessively low temperatures of covered components of the drive train. Contents of the invention [0003] The object of the invention here is to prov...
