Abstract: The invention is characterized in that the gas exchange valves of a cylinder are displaced in a displacement unit (15, 34) jointly and independently of the displacement of the displacement devices of the other cylinders. Every displacement unit (15, 34) is associated with separate actuators for actuating the same. Angle of rotation sensors (42, 43) are provided to detect the angle or rotation signals of the crankshaft and the camshaft or any other shaft rotating at half the crankshaft speed. These angle of rotation signals are used to derive the common idle phase of all valves of a cylinder to be jointly adjusted, a control unit (44) effecting the displacement of every displacement unit (15, 34) during said common idle phase.

Abstract: The aim of the invention is to fulfill, in a way that is superior to that of the previous state of the art, the demands placed by the engine on a variable valve control with regard to the shaping and accuracy of the valve lifting curves, to the simplicity of the structural design of the valve drive and of the associated adjusting mechanism, and to mechanical losses due to friction. These demands are met without any additional structural complexity, and, more particularly, without any changes to the overall height. This feat is achieved by means of the provision of a rotatable drive consisting of a housing (G), a shaft (W), an intermediate element (Z), and of an output element (A).

Abstract: The invention relates to a device for the variable actuation of the gas exchange valves of internal combustion engines, whereby a continuously revolving cam drives an intermediate member which carries out an oscillating, pure rotational movement and moves a drive member in accordance with the respective valve lift curve via a control cam. In order to modify the valve lift curve, the position of the rotational axis of the intermediate member can be modified along an advance curve. The rotational axis of the intermediate member is represented by a pin which is freely rotatable at its guide end and which carries cam plates that are linked therewith in a rotationally fixed manner. Said cam plates define either directly or indirectly the respective required position on the advance curve. The pin is rotated via a suitable joining element.

The intermediate member is supported by a curve joint on the case, with the curve of the curve joint, located on the intermediate member, having a portion forming a locking device and also a control portion. The position of the curve supported on the case and associated with this curve joint or the position of the pivot joint of the cam is adjustable during operation.

Abstract: 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.

Abstract translation: 用于致动内燃机中的阀的装置包括壳体和凸轮机构，该凸轮机构包括可旋转地连接到壳体的凸轮。 凸轮在凸轮/挺杆接口处接合挺杆，并且挺杆接合挺杆/驱动连杆接口处的输出连杆。 在凸轮旋转期间，凸轮导致在输出连杆中发生加速。 驱动连杆在两个方向中任一方向上交替移动，并且可操作地设置在壳体内，使得驱动连杆将其运动传递到阀。 凸轮成形为使得在阀闭合和重新打开之间的间隔中，由凸轮在正向方向上的凸轮/挺杆接口处传递的加速度基本上是恒定的并且远离凸轮。 在操作循环的部分期间，各种机械连杆仅通过惯性力的作用而保持接触，从而减少对额外的弹簧的需要，例如通常用于保持中间连杆或挺杆与凸轮之间的接触。 在阀关闭期间，支撑元件或止动件接合输出连杆，使得驱动连杆在挺杆/驱动连杆接口处不接合挺杆。 这在发动机运行期间提供了更高的线性加速度和增强的挺杆/驱动链接界面的润滑。

Abstract: The invention relates to a revolving gear consisting of a housing (G), a shaft (W), an intermediate member (Z) and an output member (A). The shaft is revolvably guided in the housing in a rotating joint (wb) and actuates the intermediate member by means of a curved joint (zw). The intermediate member is supported by a curved joint (zg) in the housing and is actively connected to the output member by another curved joint (za). The curved joint between the intermediate member and the housing has a controlling section enabling movement to be transmitted to the output member and a locking section preventing movement from being transmitted to the output member. The output member is unequivocally guided in the housing and transmits movement to at least one valve (V).

Abstract: 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.

Abstract: A disc clutch wherein at least one first clutch disc, having internal teeth mating with the external splines of a first rotary hub, frictionally engages at least one second clutch disc, having external teeth mating with the internal splines of a second rotary hub coaxial with the first hub, when the clutch is engaged. Engagement of the clutch takes place in response to actuation of a cylinder-piston unit having a reciprocable piton which can directly or indirectly bear upon one of the two outer discs of the package including the first and second discs. The splines of the hubs and/or the teeth of the clutch discs are capable of undergoing deformation, particularly elastic deformation, to thus facilitate a more accurate selection of the magnitude of torque to be transmitted between the hubs by way of the frictionally engaged clutch discs.
