Abstract
A force transmission device for a variable valve drive of an internal combustion engine. The force transmission device has a first lever device. The first lever device has a first cam follower and a first receptacle for the first cam follower. The first cam follower is displaceable and lockable in the first receptacle. The force transmission device has a second lever device. The second lever device has a second cam follower and a second receptacle for the second cam follower. The second cam follower is displaceable and lockable in the second receptacle.
Claims18
A force transmission device for a variable valve drive of an internal combustion engine with at least one gas exchange valve and with a camshaft having a first cam and a second cam, wherein the force transmission device comprises:
- a first lever device by means of which an operative connection can be produced between the first cam and the at least one gas exchange valve, wherein the first lever device has a first cam follower, which makes contact with the first cam, and a first receptacle for the first cam follower, and the first cam follower is displaceable and lockable in the first receptacle;
- and
- a second lever device, by means of which an operative connection can be produced between the second cam and the at least one gas exchange valve, wherein the second lever device has a second cam follower, which makes contact with the second cam, and a second receptacle for the second cam follower, and the second cam follower is displaceable and lockable in the second receptacle.
A variable valve drive for an internal combustion engine, comprising:
- a camshaft with a first cam and with a second cam which is arranged offset with respect to the first cam in a longitudinal direction of the camshaft;
- at least one gas exchange valve;
- and
- a force transmission device including:
- a first lever device by means of which an operative connection can be produced between the first cam and the at least one gas exchange valve, wherein the first lever device has a first cam follower, which makes contact with the first cam, and a first receptacle for the first cam follower, and the first cam follower is displaceable and lockable in the first receptacle;
- and
- a second lever device, by means of which an operative connection can be produced between the second cam and the at least one gas exchange valve, wherein the second lever device has a second cam follower, which makes contact with the second cam, and a second receptacle for the second cam follower, and the second cam follower is displaceable and lockable in the second receptacle.
A motor vehicle, comprising:
- a camshaft with a first cam and with a second cam which is arranged offset with respect to the first cam in a longitudinal direction of the camshaft;
- at least one gas exchange valve;
- and
- a force transmission device including:
- a first lever device by means of which an operative connection can be produced between the first cam and the at least one gas exchange valve, wherein the first lever device has a first cam follower, which makes contact with the first cam, and a first receptacle for the first cam follower, and the first cam follower is displaceable and lockable in the first receptacle;
- and
- a second lever device, by means of which an operative connection can be produced between the second cam and the at least one gas exchange valve, wherein the second lever device has a second cam follower, which makes contact with the second cam, and a second receptacle for the second cam follower, and the second cam follower is displaceable and lockable in the second receptacle.
