  • Patent number: 9808868
    Abstract: A hand-held power tool is provided which includes a clutch housing of a torque clutch, and a planetary gear, situated in a gear housing, for transmitting a torque which is generated by a drive motor to a drive shaft. The clutch housing cooperates with the planetary gear via a pressure plate. The pressure plate is displaced in the axial direction in order to disengage the torque clutch. The axial relative motion of the pressure plate causes an axial relative motion between a switching element and an associated optical sensor, via which the drive motor may be switched off.

  • Patent number: 9764391
    Abstract: The invention relates to a power drill, having a tool-clamping device that is fastened to a spindle shaft, having a torque clutch that includes an axially movable clutch plate on which an axial force is exerted by a plurality of compression springs that cooperate at least indirectly with an adjusting nut situated on a housing component. The compression springs are accommodated in first recesses embodied in the longitudinal direction of the housing component. A device for axially moving an axial bearing situated on the spindle shaft, is provided at the end of the spindle shaft oriented toward the tool-clamping device. According to the invention, on its side oriented toward the clutch plate, the device for axially moving the axial bearing has at least one actuating section that is situated in a second recess of the housing component and on the side oriented toward the clutch plate, cooperates with an adjusting element for the device.

  • Publication number: 20170016383
    Abstract: A cooling system (10) for a vehicle has a high temperature cooling circuit (11) for cooling a drive assembly (13) and an exhaust gas turbocharger (14) and has a low temperature cooling circuit (12) for cooling a charge air cooler (19). The high temperature cooling circuit (11) and the low temperature cooling circuit (12) are coupled via a coupling line (25), into which a nonreturn valve (26) is connected. The nonreturn valve (26) is opened or closed depending on the pressure ratio between the high temperature cooling circuit (11) and the low temperature cooling circuit (12). The high temperature cooling circuit (11) and the low temperature cooling circuit (12) can be vented via a common cooling water compensation tank (21) only in defined operating states when the nonreturn valve (26) of the coupling line (25) is open.
