Problems solved by technology

[0005] In addition, this external volume must be filled with oil, thus also increasing the total amount of oil
Therefore, the inertia of the system increases
Furthermore, the oil cooler has to be arranged and fastened mechanically, either by means of a surrounding holding device or by means of a separate holding device, which requires additional fastening means and also requires installation space

Embodiment Construction

[0023] figure 1 A schematic sectional view of a screw compressor 10 in the sense of an embodiment of the invention is shown.

[0024] The screw compressor 10 has a fastening flange 12 for mechanically fastening the screw compressor 10 to an electric motor, not shown in detail here.

[0025] However, an input shaft 14 is shown, via which the torque of the electric motor is transmitted to one of the two spindles 16 , 18 , namely the spindle 16 .

[0026] The screw 18 meshes with the screw 16 and is driven via it.

[0027] The screw compressor 10 has a housing 20 in which the main components of the screw compressor 10 are arranged.

[0028] The housing 20 is filled with oil 22 .

[0029] On the air supply side, an inlet connection 24 is provided on the housing 20 of the screw compressor 10 . The inlet connection 24 is designed in such a way that an air filter 26 is arranged thereon. Furthermore, an air inlet 28 is provided radially on the air inlet connection 24 .

Abstract

The invention relates to a screw compressor system (100) for a utility vehicle, comprising at least one screw compressor (10), at least one screw compressor drive, at least one temperature probe (38)and at least one control and regulation unit (110). Said control and / or regulation unit (110) is connected to the screw compressor drive and to the temperature probe (38) and is designed and configured such that it controls, in accordance with a temperature threshold signal obtained from the temperature probe (38), the screw compressor drive with respect to a rotational speed.

Description

technical field [0001] The invention relates to a screw compressor system for a commercial vehicle having at least one screw compressor with an open loop and / or for said screw compressor Or at least one open-loop and / or closed-loop control unit for closed-loop drive control. Background technique [0002] Screw compressors for commercial vehicles are known from the prior art. Such screw compressors are used, for example, to supply the necessary compressed air for the brake systems of commercial vehicles. [0003] In this connection, in particular oil-filled compressors are known, in particular also screw compressors, in which the task of regulating the oil temperature is present. This is usually achieved by means of an externally arranged oil cooler, which is connected to the oil-filled compressor and the oil circuit via a thermostatic valve. The oil cooler is here a heat exchanger with two separate circuits, wherein a first circuit is provided for the hot fluid, ie compre...
