摘要： The present invention provides a disassemblable camshaft for internal combustion engines features a cylindrical shaft which in a single operation can be inserted in the bearing bores and cams arranged in between, so that undivided bearings of relatively small diameter can be used. The cams are joined in rotationally fixed fashion to the shaft by pinch-fitting them on the shaft. Transverse screw joints utilizing tensionally stressed clamping screws improve the fixed joint between the cam and both the conic sleeve and shaft. The screw joints are fashioned in a manner such that no additional construction space is needed as compared to conventional camshafts and assembly can be performed with only standard tools.

摘要： A device for actuating a valve in an internal combustion engine consists of a casing and a cam mechanism including a cam which is rotatably joined to the casing. The cam engages a tappet at a cam/tappet interface and the tappet engages a output link at a tappet/drive link interface. During cam rotation, the cam causes an acceleration to occur in the output link. The drive link moves alternately in either of two directions and is operably disposed within the casing so that the drive link transmits its motion to the valve. The cam is shaped such that in the interval between valve closure and reopening, the acceleration transmitted by the cam, at the cam/tappet interface in normal direction, is substantially constant and is directed away from the cam. During portions of the cycle of operation, the various mechanical links are kept in contact solely by the effect of inertial force thereby reducing the need for additional springs, such as commonly used to maintain contact between the intermediate link or tappet and the cam. A support element or stop engages the output link during valve closure such that the drive link does not engage the tappet at the tappet/drive link interface. This provides more linear acceleration and enhanced lubrication at the tappet/drive link interface during engine operation.

摘要： A method is described for monitoring wheel speeds, having the following steps: determining the wheel speeds, determining the wheel having the maximum wheel speed, determining the wheel having the minimum wheel speed, determining the differential speed between the maximum wheel speed and the minimum wheel speed, and comparing the differential speed to a threshold value, if the differential speed is greater than a threshold value, the wheel having the maximum wheel speed being registered as the fastest wheel and the wheel having the minimum wheel speed being registered as the slowest wheel, in event of a change of the wheel speeds, so that another with wheel is the fastest wheel and/or another wheel is the slowest wheel, the fastest wheel being registered and the slowest wheel being registered and a logical status being established from the registered values and the instantaneous values. A device for monitoring wheel speeds in accordance with the above method is also described.

摘要： A device for monitoring a pressure sensor, which is positioned in a braking system of a vehicle. For this purpose, the device contains arrangement with which, during a braking action, a first vehicle motion variable is ascertained, which characterizes a vehicle motion in the longitudinal direction. The device further includes arrangement with which a mass variable is ascertained, which characterizes the mass of the vehicle. Using further arrangement, it is ascertained, for the monitoring of the pressure sensor, whether the first vehicle motion variable lies within a value range for the first vehicle motion variable, whose limits are ascertained as a function of the mass variable.
