Definitions
- the invention is based on an internal combustion engine valve drive device for a motor vehicle, with at least one shift gate, which is intended to convert a rotational movement of at least one cam element into axial movement of the at least one cam element for stroke switching, with at least one first actuator provided for this purpose Active connection with the shift gate to move a first cam member axially in a switching direction, with at least one second actuator, which is intended to axially displace a second cam member in the same switching direction by an operative connection with the shift gate, and with a control and / or control unit. It is proposed that the control and / or regulating unit is provided for simultaneously controlling and / or monitoring the at least two actuators for the axial displacement of the at least two cam elements in the same switching direction.
- the internal combustion engine valve drive device has at least the third actuator, wherein the third actuator is electrically connected in parallel or in series with the first actuator and the second actuator and is provided, by an operative connection with the shift gate, the first cam element and / or the axially displacing the second cam member in a shift direction opposite to the shift direction provided by the first actuator and the second actuator.
- the third actuator is electrically connected in parallel or in series with the first actuator and the second actuator and is provided, by an operative connection with the shift gate, the first cam element and / or the axially displacing the second cam member in a shift direction opposite to the shift direction provided by the first actuator and the second actuator.
- the camshaft 24a comprises a drive shaft 30a.
- the drive shaft 30a includes a crankshaft connection for connection to a crankshaft, not shown, of the internal combustion engine.
- the crankshaft connection can be formed by means of a camshaft adjuster which is provided to set a phase position between the camshaft 24a and the crankshaft.
- control and regulation unit 18b can additionally or alternatively monitor the actuators 15b, 17b, 20b, 22b, whereby all other actuators 5b, 17b, 20b, 22b are deactivated upon detection of a defective or nonfunctional actuator 15b, 17b, 20b, 22b, and optionally a warning message is issued.
