Definitions

  • the cylinder of an internal combustion engine can be operated in two different operating modes. If only a single cam is used instead of two cams with different lifts and - instead of a second cam - a base circle without a cam lift is used, the cylinder can be switched off with the aid of the valve drive. In such a switched-off state, a cam follower coupled to a gas exchange valve of the cylinder does not interact with the single cam, but with said base circle, so that the gas exchange valve is not actuated.
  • a valve train of the type mentioned is from DE 199 45 340 A1 known. Also from the JP 2014 224496 A , of the EP 2 487 341 A1 , of the DE 10 2009 005731 A1 , of the US 2014/190432 A1 and the WO 2005/080761 A1 such adjustable valve trains are known in each case,
  • the basic idea of the invention is therefore to equip a valve drive with a purely mechanical adjustment device, by means of which the cam follower can be adjusted between a first and a second axial position.
  • the use of conventional adjustment means with pneumatic or hydraulic components can be dispensed with in this way. This means a considerably simplified structural design of the valve drive, which in turn results in a reduced space requirement.
  • a valve train according to the invention comprises a camshaft and a cam follower.
  • a first cam and, axially adjacent to it, a second cam are attached to the camshaft in a rotationally fixed manner.
  • An axial direction can be defined by the central longitudinal axis of the camshaft.
  • the first cam can be arranged axially at a distance from the first cam or bear against it.
  • the cam follower is axially adjustable along an axial direction.
  • the cam follower is axially adjustable between a first position in which the cam follower is drivingly connected to the first cam and a second position in which the cam follower is drivingly connected to the second cam.
  • the cam follower has a mechanical adjustment device which interacts with the camshaft for the axial adjustment of the cam follower between the first and the second position.
  • the mechanical adjusting device has an adjustable first mechanical engagement element. In order to axially adjust the cam follower from the first to the second position, this interacts with a first link guide present on the camshaft.
  • the adjustment device also has a second mechanical engagement element that can be created and that interacts with a second link guide present on the camshaft for the axial adjustment of the cam follower from the second to the first position.
  • the mechanical adjustment device comprises a first actuator.
  • the first mechanical engagement element is by means of the first actuator adjustable between a first position in which it engages in the first link guide and a second position in which it does not engage in the first link guide.
  • the mechanical adjustment device comprises a second actuator, by means of which the second mechanical engagement element can be adjusted between a first position in which it engages the second link guide and a second position in which it does not engage the second link guide.
  • the use of such actuators also makes it possible to dispense with pneumatic and / or hydraulic adjustment means for adjusting the respective engagement element, which can be technically implemented only with considerable effort.
  • the adjustment of the first and / or second engagement element from the first to the second position takes place with the aid of the lifting movement of the cam follower.
  • the cam follower is moved towards the two actuators by the lifting movement caused by the first or second cam. If these are in their active position, the lifting movement of the cam follower and thus of the respective engagement element pushes the respective engagement element against the respective, stationary, i.e. immovable, actuator in the active position relative to the camshaft and in this way moves the actuator into its second position "moved".
  • An active adjustment of the first or second engagement element by an active movement of the first or second actuator can be dispensed with in this way.
  • the two actuators can be constructed in a very simple manner, which leads to cost advantages in production.
  • the first actuator is expediently adjustable between an inactive position and an active position.
  • the adjustability can preferably be realized in such a way that the first actuator is out of contact with the first engagement element in the inactive position and the first engagement element is moved from the inactive position to the active position through mechanical contact with the second adjusted to the first position.
  • the second actuator as an alternative or in addition to the first actuator, can also be adjustable between an inactive position and an active position.
  • the second actuator is also out of contact with the second engagement element in the inactive position. By moving from the inactive position to the active position, the second actuator moves the second engagement element from the second to the first position by mechanical contact.
  • the two actuators can particularly preferably be designed as linearly adjustable, electrically driven actuators. In this case, they can be controlled in a simple manner by a control device of the valve drive for adjusting between the active position and the inactive position.
  • the implementation as electrical actuators allows a very precise control of the linear positioning of the actuators along their direction of adjustment.
  • the mechanical adjustment device is implemented as an electromechanical adjustment device.
  • the first actuator has a linearly adjustable first adjusting element.
  • This can comprise a cylindrical adjusting body, the end face of which presses against an end face of the engagement element opposite the first adjusting element when the first engagement element is moved into the first link guide.
  • the second actuator can also have a linearly adjustable second adjusting element which has a cylindrical adjusting body. Its end face can, in a manner analogous to the first adjusting element, when moving the second engagement element into the second Push the link guide against an end face of the second engagement element opposite the second adjusting element.
  • the desired mechanical coupling of the actuator to the engagement element can be implemented in a simple and thus inexpensive manner.
  • the first actuator has a housing and a first adjusting element that is translationally adjustable relative to the housing between the first and the second position.
  • the second actuator as an alternative or in addition to the first actuator, can also have a housing and a second adjusting element which is translationally adjustable relative to this housing between the first and the second position.
  • the first and second link guides are formed in a common link body which is arranged axially on the same side of the cam follower roller relative to the two cams.
  • the cam follower has a cam follower fixing device for releasably fixing the cam follower in the first or second position.
  • the cam follower fixing device has a spring-loaded cam follower fixing element. This engages in the first position of the cam follower in a first receptacle provided on the cam follower and in the second position of the cam follower in a second receptacle provided on the cam follower.
  • the first receptacle as a first circumferential groove formed on the circumferential side of the cam follower.
  • the second receptacle is designed as a second circumferential groove arranged axially on the circumferential side at a distance from the first circumferential groove.

This is received in the first position of the engagement element in a first receptacle provided on the engagement element. In the second position of the engagement element, the fixing element is received in a second receptacle provided on the cam follower.
  • the first and / or second engagement element preferably each have a bolt-like or pin-like base body, on the circumferential side of which the first receptacle is designed as a first circumferential groove and the second receptacle is designed as an axially spaced second circumferential groove.
