Problems solved by technology

This necessity makes the use of such couplings inflexible and makes flush alignment for connecting two shafts difficult, especially in confined and inaccessible environments. such a situation
The same difficult situation arises for replacement when either the auxiliary unit fails or the drive unit providing the torque fails and must be replaced

Embodiment Construction

[0024] figure 1 The device 10 shown in includes: a drive unit 12 with a housing 14; and an auxiliary unit 16 with another housing 18; and a rotatable member 20, wherein the drive unit 12 is constituted in the illustrated embodiment as The electric motor 22 in the form of an asynchronous motor 24 and the auxiliary unit 16 are in the form of a compressor 26 , for example a piston compressor 28 . The auxiliary unit 16 can be constructed in various conceivable forms and can be driven by the drive unit 12 by means of torque, for example as an air compressor, an air conditioning compressor 27 for conditioning the air in the vehicle, or as a supporting Steering pump 29 for vehicle steering.

[0025] The piston compressor 28 comprises a shaft 30 which is embodied as a crankshaft 32 and which is mounted by means of a bearing 34 , in particular by means of a roller bearing, wherein various types of bearings 34 suitable for supporting the shaft can be used. The crankshaft 32 has a firs...

Abstract

The present invention relates to a device for operating an auxiliary assembly (16), comprising a housing (14), of a vehicle, in particular of a utility vehicle, having a drive unit (12) which comprises a further housing (18) and has the purpose of making available a torque, a shaft (30) for transmitting the torque from the drive unit (12) to the auxiliary assembly (16), wherein the shaft (30) projects into the housing (14) of the auxiliary assembly (16) or into the further housing (18) of the drive unit (12). Furthermore, the drive unit (12) and the auxiliary assembly (16) form a common coolant circuit (52) for cooling the drive unit (12) and the auxiliary assembly (16).

Description

technical field [0001] The invention relates to a device for operating an auxiliary unit comprising a housing of a vehicle, in particular a commercial vehicle, which has a drive unit comprising a further housing for providing torque; the device also has a A shaft for transmitting the torque of a drive unit to an auxiliary unit and the invention relates to a vehicle having such a device. Background technique [0002] Such devices are known from the prior art and are very commonly used for operating auxiliary units in all types of vehicles. Typically, torque must be introduced from the drive unit into the auxiliary unit in order to be able to operate the auxiliary unit. In most cases, the torque is introduced into the auxiliary unit via a rotatably mounted shaft, wherein the shaft is connected to the drive unit via a coupling. All types of couplings can be used here, for example rotationally rigid, elastic or switchable couplings. Depending on the type of construction, the ...
