摘要： A device for switching activation of a hydraulic valve play equalization element for setting of a maximal stroke or a zero stroke on a valve of an internal combustion engine, has a switching element for locking and unlocking the housing of the valve play equalization element relative to a guide that is axially displaceable therein. The switching element is a switching ring that surrounds the housing, on which a linkage for rotating the switching ring relative to the housing is disposed. The linkage of the switching ring is connected via a guide element with a groove on the circumference of a rotatable adjustment shaft. The groove has a groove section demonstrating an axial incline, and in which the switching ring is rotated, to implement a switching process via the guide element during rotation the adjustment shaft.

摘要： The invention relates to a method and an associated device for simulating the driving characteristics of a drive concept to be developed for a motor vehicle. The aim of the invention is to provide a method and an associated device for simulating the driving characteristics of a drive concept to be developed for a motor vehicle, using which the longitudinal dynamics and the energy requirements of designed concepts are simulated, compared with one another and validated during an actual driving operation. According to the invention, in order to simulate the driving characteristics of a drive concept to be developed for a motor vehicle during an actual driving operation for a production vehicle, the engine and transmission control are influenced by means of an additional control unit in such a way that the longitudinal dynamics of the production vehicle correspond to that of a designed hybrid drive. To achieve this, the additional control unit for influencing the longitudinal dynamics of the conventional carrier vehicle intervenes in the signal path of the accelerator pedal in the carrier vehicle and can determine the position of the pedal, simulating the position of a ‘virtual accelerator pedal’ by means of a signal generator, thus regulating the acceleration of the vehicle. The control unit accesses the CAN data bus of the drive train of the carrier vehicle to deliver the current speed, the current gear selected and the position of the brake pedal, which represent important input variables for the simulation.

摘要： Valve gears for load-change valves of four-stroke internal combustion engines, in which the load-change valves are closed by spring force, engage a pivot lever moved by a cam for opening a load-change channel. The cam engages an intermediate element that it is additionally moved by the lifting curve of the cam during a different work cycle, and adjusts the pivot lever to open the load-change valve slightly during a different work cycle. The intermediate element is prismatically guided on an element that can pivot in the cylinder head and is adjustable in its position, and engages the cam and the pivot lever, so that the stroke movement of the cam for opening the load-change valve via the pivot lever can be adjusted.
