Abstract
A valve train of an internal combustion engine includes at least one basic camshaft with a cam carrier provided thereupon in a rotationally fixed and axially displaceable manner. The cam carrier has at least one valve-actuating cam as well as a tubular basic element that receives the basic camshaft in at least some sections. At least one cam element of the cam carrier, in particular the valve-actuating cam, is arranged on the basic element. At least one torque-transmitting connecting element is located between the basic element and the cam element. An internal combustion engine having at least one valve train and a method for producing a valve train are also disclosed.

A valve train of an internal combustion engine, comprising:
- at least one basic camshaft,
- a cam carrier comprising at least one valve-actuating cam with is arranged on the at least one basic camshaft in a rotationally fixed and axially displaceable manner, a tubular basic element that at least partially accommodates the basic camshaft, and at least one cam element disposed on the tubular basic element, and
- at least one torque-transmitting connecting element arranged between the tubular basic element and the at least one cam element.
An internal combustion engine having at least one valve train, with the at least one valve train comprising:
- at least one basic camshaft,
- a cam carrier comprising at least one valve-actuating cam with is arranged on the at least one basic camshaft in a rotationally fixed and axially displaceable manner, a tubular basic element that at least partially accommodates the basic camshaft, and at least one cam element disposed on the tubular basic element, and
- at least one torque-transmitting connecting element arranged between the tubular basic element and the at least one cam element.
A method for producing a valve train, comprising the steps of:
- providing a basic element,
- preparing at least one retaining opening in the basic element,
- inserting a torque-transmitting connecting element into the retaining opening, and
- pushing at least one cam element over the connecting element.
