Embodiment Construction

[0032] figure 1 A cross-sectional illustration is shown through an embodiment of a coolant pump 15 according to the invention. The coolant pump 15 has a pump wheel 13 arranged on the pump wheel shaft. The pump shaft is divided into a driving section 3 and a driven section 11 . In the illustrated embodiment, the active section 3 is formed as a flange to which a mechanical drive 1 (in the example in the form of a pulley) is rotationally fixedly connected. In the illustrated embodiment, the arrangement consisting of a flange 3 and a pulley 1 is mounted in a housing 7 via a bearing (not shown).

[0033] The mechanical drive 1 can be connected to the internal combustion engine of a motor vehicle, wherein in the embodiment shown it is possible to use a belt drive, however only the pulley 1 of the belt drive is shown in order to simplify the illustration.

[0034] The driven section 11 of the impeller shaft is mounted in the housing 7 via two bearings 5 ​​and 10 and supports the i...

Abstract

The invention relates to a coolant pump (15) having a pump wheel (13) which is arranged on a pump wheel shaft (3, 11); and having a drive device (1; 8, 9) for the pump wheel (13), which drive device has a mechanical drive (1) and which drive device has an electric-motor drive (8, 9), wherein the pump wheel shaft is divided into a driving section (3) and a driven section (11), and an openable and closable clutch (4) is arranged between the driving section (3) and the driven section (11).

Description

technical field [0001] The invention relates to a coolant pump according to the preamble of claim 1 . Background technique [0002] A coolant pump of the type mentioned is known from DE 102 14 637 A1. [0003] In order to be able to realize different drive operating states of the vehicle with the coolant pump, which has both an electric motor drive and a mechanical drive, there is provided a planetary drive. [0004] However, said design is complex and prone to failure in terms of its mechanical construction. Contents of the invention [0005] It is therefore the object of the present invention to create a coolant pump of the type defined in the preamble of claim 1 , whose design is simplified with respect to the prior art and whose operation is efficient. and fail-safe. [0006] Said object is achieved by the features of claim 1 . [0007] Since the pump impeller shaft is divided into a driving section and a driven section separate from said driving section, and sinc...
