Embodiment Construction

[0026] exist figure 1 3 shows a pivoting lever arrangement 1 with two pivoting levers 2 , 3 , which are each pivoted laterally onto a shaft 6 with bore holes 4 , 5 . The shaft 6 is fastened with screws 7 to a bearing block 8 which itself extends laterally below the area of ​​the tilting levers 2 , 3 .

[0027] For axial positional security of the pivoting levers 2 , 3 , a protruding insert element is formed on these pivoting levers, pointing toward the bearing block. These insert elements are designed as ring web parts 9 , 10 and are tongue elements of a tongue-and-groove connection. The groove elements as counter elements are cut out on the one-piece support block 8 as annular groove parts 11 , 12 , for example by milling.

[0028] especially by figure 2 It can be seen from the side view that the ring web parts 9 , 10 extend laterally beyond the area of ​​the bearing block 8 to such an extent that the ring web parts 9 , 10 and The axial side supports between the associat...

Abstract

The invention relates to a bearing of a rocker arm (2, 3) for a valve train of an internal combustion engine having a bearing bock (8) in which a shaft (6) is arranged on the rocker arm (2, 3) with an associated bore (4, 5 ) is pivotally attached and held by means of an axial securing the position. According to the invention, an axial positional securing is a guide connection device of an engaging element counter-element connection between the bearing block (8) and the rocker arm (2, 3), wherein an engagement element (9, 10) oriented transversely to an axial is inserted into an associated counter-element (11, 12) with axial edge support (16, 17) pivotally engaged.

Description

technical field [0001] The invention relates to a mounting device for a tilting lever of a valve train of an internal combustion engine. Background technique [0002] The generally known bearing device of the tilting lever comprises a pivoting lever bearing block, on which a shaft is arranged, and one or two tilting levers are inserted pivotably through an associated borehole and are mounted by means of an axial position. state insurance to hold onto the axis. This position assurance takes place via the contact surface on the side of the tilting lever. These flanks are produced in particular by alignment of forged blanks or by mechanical machining. On the side of the bearing block, the fixation also takes place via correspondingly machined surfaces and by means of spacers and securing rings. [0003] Furthermore, axial position assurance between the pivot lever and the shaft is known. For example, for this purpose, the area of ​​the shaft surrounded by the bore of the ti...
