摘要:
The invention refers to an impeller, consisting of plastic, which Is intended for a coolant pump of an internal combustion engine. The impeller, which has a multipart construction, comprises a back wall, which is connected in one piece to guide vanes and also to a hub, and also a separate molded disk which on the end face partially covers the guide vanes in the installed state. The components, the back wall and the molded disk are positionally fixed by means of a materially bonding connection.

A lip-type shaft seal is made of elastic material with a Shore A hardness of ≦75, includes a radial sealing lip, which has a sealing edge to bear against a rotating component and terminates in a axial sealing lip, which has a sealing edge to rests in installed state against a contact surface. The axial sealing lip extends at an angle of ≧35° in relation to a symmetry axis of the shaft seal, when the axial sealing lip has not been installed yet and is under no tension, and extends from the sealing edge of the radial sealing lip at a length of ≧1.4 mm. When the shaft seal is installed, the axial sealing lip rests against the contact surface at an axial overlap of 0.05 to 0.55 mm.
摘要:
A heat management module of a cooling system of an internal combustion engine which has a valve housing that includes at least one first feed connection for cooling water of a bypass circuit and at least one adjacent second feed connection for cooling water of a radiator circuit. The feed connections can be connected to a discharge connection depending on the position of a valve member accommodated in the valve housing. A driving element which actuates the valve member is provided on the valve housing. The driving element is a hydrostatic servo motor, which produces a rotating driving motion and which uses a feed pressure line that branches from the cooling system for pressurization.
摘要:
A thermal management module for the distribution as required of coolant flows in an electric vehicle, including a valve arrangement (4) having several valves (1, 2, 3). A first valve (1) for connecting a first cooling circuit (5) and a second valve (2) for connecting a second cooling circuit (6) as well as a third valve (3) for connecting a bypass circuit are provided, wherein the bypass circuit (7) allows bypassing a cooler (8) arranged in the first cooling circuit (5). The invention further relates to a cooling system for an electric vehicle having such a thermal management module.
