Problems solved by technology

When the magnetic coil actuator is energized, it suddenly generates its maximum force, which can lead to a large pressure load on the switching lever with a large force peak and can cause the switching lever to Deformation or compression of the corrugation together with further loss of travel and can lead to damage

Embodiment Construction

[0025] exist figure 1 The apparatus for manipulating at least one switchable gas mechanism member for manipulating an internal combustion engine is shown in the present invention has an actuator 1 and a deflection unit 2. The deflection unit can be rotatably driven around the rotary axis 3 by an actuator 1. according to figure 2 The deflection unit 2 is configured by the axis 4 that is rotatably driven around the rotary axis 3 and the axial member 5 which is resistant to the axis in which the axis is formed. The carrier element 5 is disposed on the end side of the free end side of the shaft 4 as a cylindrical axis 6 and the rotating axis 3 axis 6 as the cylindrical axis 6 ( figure 2 ). The carrying element 5 is bonded to an elongated opening 7 in a manner parallel to the axis of rotation 3, the opening on the manipulation unit 8 that is movably disposed for switching ( figure 1 with 3 ). The manipulation unit is configured as a long-shaped rod flat member having two wide flat long...

Abstract

The invention relates to a device for actuating at least one switchable valve train component for an internal combustion engine, comprising an actuating unit (8) which is arranged so as to be movable along a movement axis (11) for switching the valve train component, characterized in that a deflection unit (2) which can be rotationally driven by an actuator (1) about an axis of rotation (3) is provided, the deflection unit (2) interacts with at least one opening (7) on the actuating unit (8) in such a way that a rotational movement of the deflection unit (2) can be converted into an axial movement of the actuating unit (8) for switching in a guided manner at the opening (7).

Description

Technical field [0001] The present invention relates to an apparatus for manipulating at least one switchable ventilation mechanism member for an internal combustion engine. Background technique [0002] A variable gas supply mechanism of a internal combustion piston engine is known from DE 10 2017 101 792, which has a switching rod that is movably disposed by means of a linear actuator. Through the rod-shaped connecting element, the switching rod is adjusted to form a handover plug for switching the switchable towers. Here, the switching plug for switching is movably supported in the lateral hole of the trace bar. The linear actuator is configured as a simple electrical magnetic coil actuator that presses the switching rod via the connecting plate to move, where the elasticity of the connecting plate causes the stroke loss. When energizing the magnetic coil actuator, the magnetic coil actuator suddenly produces its maximum force, which can result in a large pressure load having ...
