Slide cam system and motor

A slide cam system for an internal combustion engine having a camshaft comprising:

• a carrier shaft having a first slide cam element and a second slide cam element that each comprise at least one switching member and a switching groove, wherein the switching groove of the first slide cam element includes a first switching groove that includes an at least partially Y-shaped profile;
• an actuator pin, wherein the first and second slide cam elements are displaceable axially relative to the carrier shaft by the actuator pin;
• and
• a displacement element disposed parallel with a longitudinal axis of the carrier shaft, wherein the displacement element is axially displaceable in a direction of the longitudinal axis of the carrier shaft, wherein the displacement element comprises:
• a first coupling pin that is disposed in a region of the first slide cam element, wherein the switching groove of the first slide cam element further includes a second switching groove configured to receive the first coupling pin that is arranged such that the displacement element is directly displaceable, and
• a second coupling pin that is disposed in a region of the second slide cam element, wherein the first and second coupling pins cooperate with the switching member of the respective first and second slide cam elements such that as a result of the displacement element a movement initiated by the actuator pin of the first slide cam element is configured to be transmitted to the second slide cam element wherein the second switching groove is at least partially disposed centrally in the at least partially Y-shaped profile of the first switching groove, wherein the second switching groove extends over an entire periphery.

A slide cam system for an internal combustion engine having a camshaft comprising:

• a carrier shaft having a first double slide cam element and a second double slide cam element that control valves of cylinders, wherein the first and second double slide cam elements each comprise:
• a slotted switching member having a switching groove, and
• a cam portion having a stroke cam contour;
• an actuator pin, wherein the first and second double slide cam elements are displaceable axially relative to the carrier shaft by the actuator pin;
• and
• a displacement element disposed parallel with a longitudinal axis of the carrier shaft, wherein the displacement element is axially displaceable in a direction of the longitudinal axis of the carrier shaft, wherein the displacement element comprises:
• a first coupling pin that is disposed in a region of the first double slide cam element, and
• a second coupling pin that is disposed in a region of the second double slide cam element,
• wherein the first and second coupling pins cooperate with the slotted switching member of the respective first and second double slide cam elements such that a movement of the first double slide cam element initiated by the actuator pin is configured to be transmitted to the second double slide cam element by the displacement element, and
• wherein the displacement element comprises a receiving element, wherein the carrier shaft comprises a locking element that cooperates with the receiving element during operation of the slide cam system such that the displacement element is locked between two positional changes.
