Abstract: A supporting body (1) for guiding or tensioning a circumferential traction mechanism of a traction drive, a front side (12) that has an elongated sliding surface for making contact with the traction mechanism, a rear side (2) that lies opposite and includes an elongated receiving groove (5) for form-fittingly receiving a reinforcement panel, the receiving groove (5) being formed by delimiting elements (3) which protrude, at the sides of the groove, from the rear side, and at least two delimiting elements (3, 3?) on one side of the receiving groove (5) being separated in the longitudinal direction by a spacing in the form of a gap (4).

Abstract: A braking apparatus for work machines has at least two brakes, each having at least one braking circuit. The braking circuits can each be actuated via at least one control valve, and the control valves can be controlled independently of one another. A processing unit, by which the control valves can be controlled or regulated, an operating circuit, via which the braking circuits can be controlled or regulated manually, and at least one pressure supply are provided, and the control valves can be controlled or regulated under predetermined conditions by the processing unit.

Abstract: The disclosure relates to a method for detecting an arc in a DC circuit. The method includes measuring and analyzing an AC component (IAC) of a current (I) flowing in the circuit and determining at least one parameter of the AC component (IAC). The level of a DC component (IDC) of the current (I) is varied and a degree of correlation between the level of the DC component (IDC) of the current (I) flowing in the DC circuit and the at least one parameter of the AC component (IAC) is determined. An arc is detected and selectively signaled based on the degree of the determined correlation. The disclosure also relates to an apparatus for carrying out the method and to an inverter comprising such an apparatus.

Abstract: The present disclosure relates to an apparatus for controlling/regulating the travel speed of a utility vehicle comprising at least one drive motor, at least one hydraulic pump, at least one control slide valve, at least one hydraulic travel motor, at least one further hydraulic drive, as well as at least one controller. In accordance with the present disclosure, the travel speed of the at least one hydraulic travel motor is controlled/regulated via at least the speed of the drive motor, while the at least one further hydraulic drive does not provide any drive power.

Abstract: A braking apparatus for work machines has at least two brakes, each having at least one braking circuit. The braking circuits can each be actuated via at least one control valve, and the control valves can be controlled independently of one another. A processing unit, by which the control valves can be controlled or regulated, an operating circuit, via which the braking circuits can be controlled or regulated manually, and at least one pressure supply are provided, and the control valves can be controlled or regulated under predetermined conditions by the processing unit.

Abstract: A carburetor assembly includes a carburetor (9) wherein a section of an intake channel (10) is configured. A throttle element and a choke element are pivotally journalled in this intake channel (10). A first coupling element is fixedly connected to the throttle element so as to pivot therewith and a second coupling element is fixedly connected to the choke element so as to pivot therewith. The first and second coupling elements form a blocking arrangement which prevents an engagement of the choke element when the throttle element is not actuated.

Abstract: An axle stub bearing unit for a bearing point of an axle stub of a steerable axle of a vehicle is provided, with a radial bearing that is constructed as a needle bearing, and a separate axial bearing that is constructed as a sliding bearing, which are accommodated in a cup-shaped bush (2, 12, 21, 25). The bush is a component which is formed in one piece and is provided with a sleeve (7, 14, 19, 26) in a region of the axial bearing.

Abstract: The inventive bearing arrangement for a device for activating a vehicle brake has a central threaded spindle (2) which is secured against torsion in a fixed housing (1) and which is arranged in such a way that it can be displaced up to a brake disk (3) of the vehicle and from thereon axially. The inventive arrangement is also provided with an inner ring (5) which concentrically surrounds the threaded spindle (2) together with roll bodies. Said inner ring (5) is coupled with a rotating rotor of an electromotor (7) at the front and is supported with the same in the housing (1) by an axial roller bearing and a radial roller bearing so that it can rotate. According to the invention, the axial roller bearing of the inner ring (5) is made up of a planetary gear with several roll bodies serving as planets. Said roll bodies are situated between the inner ring (5) and a bore wall (8) of the housing (1) which is axial to the inner ring (5). This reduces the friction losses of the axial roller bearing.

Abstract: The eccentric end portion (5) of a pump shaft (3) is mounted in a needle roller bearing (6) which comprises a sheet metal bushing (9) and needle rollers (7) guided in a cage (8), wherein the end of the sheet metal bushing (9) remote from the pump shaft (3) is provided with a closed bottom (18) to prevent a displacement of the sheet metal bushing (9) in axial direction.
