Abstract: A method is disclosed for preventing a power reduction in an electric drive system of a vehicle (3) during a journey of the vehicle. The method includes a component-tempering process (P2) in which at least one component (4, 5, 6) of the electric drive system is tempered, such that the method comprises a power reduction prediction process (P1) in which it is checked whether a power reduction is to be expected during a journey. The component-tempering process (P2) is initiated as soon as the power reduction prediction process (P1) has recognized that a power reduction is to be expected during the journey.

Abstract: A method (8) is disclosed for cooling a drive system having a first component (1), a second component (2), and a common cooling circuit (3). The drive system is designed such that the common cooling circuit (3) is suitable for cooling the first component (1) and the second component (2), where the first component (1) has a first maximum temperature and a first threshold temperature, and where the first threshold temperature is lower than the first maximum temperature. The second component (2) has a second maximum temperature, where the first maximum temperature is lower than the second maximum temperature, and when the first threshold temperature is reached a cooling performance applied to cool the second component (2) is reduced.

Abstract: The invention is wiper arm for a device for the cleaning of a windshield on a vehicle with a retaining element attached to a drive shaft to which a wiper arm part is articulated such that it can be tilted onto and away from the windshield and which is pressed down in the direction of the windshield with a force at least during the operation of the windshield washing device, and with the free end of which a wiper can be connected and with a separate trim that is attached to the wiper arm and extends in a longitudinal direction over the greater part of the length of the entire wiper arm part, and over all of the length of the wiper that is connected to the wiper arm.

Abstract: The invention relates to a four-joint wiper arm for a windshield wiper system of a motor vehicle, with the so-called four-joint consisting of a primary lever that can be connected to the primary shaft, a control lever arranged lateral to the former, that can be connected to a supporting arbor and a coupling link connected by means of one joint respectively to the free ends of primary lever and control lever. At the end at which the control lever is coupled, the joint section of the wiper arm is pivoted to the coupling link in a conventional way. In order to preclude distortion in the four-joint assembly and thereby improve the wiping quality, one of the two joints is in the form of a ball-and-socket joint between the coupling link and primary lever or control lever and the other is in the form of a universal joint.

Abstract: The invention relates to a method for producing and securing a screw in a preset position to prevent unauthorized adjustment. The screw securing means according to the invention makes it possible to secure a screw connection in a simple manner, in that a screw head of thermoplastic plastic, which is at least partly located in a housing recess, is heated to such an extent that it changes to the liquid state, flows into the housing recess, and at least partially fills the housing recess. By form-fitting engagement with the threaded pin and the housing recess, security against twisting, and also against being rotated without authorization, is attained. Screws in components that vibrate severely, and adjusting screws that must not be adjusted by unauthorized third parties, can be secured with this screw securing means.
