Embodiment Construction

[0022] exist Figures 1 to 3 The rocker arm according to the invention for a valve train of an internal combustion engine shown as an example in , is embodied from a sheet metal. The rocker is arranged with its two ends to be pivotable on the shaft 1 and is formed with two segmentally opposite side walls 2 , 3 . The rocker arm has a valve-side arm end region and a drive-side arm end region, wherein the valve-side arm end region has a handle (not shown) formed on its lower side oriented in the pivoting direction for actuating The valve contact area 4 of the gas exchange valve, the arm end area on the drive side, has a cam roller 5 arranged between the side walls 2 , 3 to intercept the camming movement. Provided on the side walls 2 , 3 are through-shaped circular receiving openings 6 , 7 for receiving the shaft 1 , which are arranged in alignment in a central region situated between the arm end regions. At the receiving openings 6 , 7 , the rocker arm is slidably mounted direc...

Abstract

The invention relates to a rocker arm for the valve mechanism of an internal combustion engine. The rocker arm is provided with accommodation openings (6,7), which are neatly arranged on opposite lateral walls (2,3). The accommodation openings are used to accommodate a shaft (1) so as to carry out bearing that can pivotally rotate. The rocker arm is characterized in that for the axial guiding of the rocker arm that can pivotally move, the guiding elements on the lateral walls (2,3) are integrated with the lateral wall.

Description

technical field [0001] The invention relates to a rocker arm for a valve train of an internal combustion engine according to the type defined in detail in the preamble of claim 1 . Background technique [0002] Such a rocker arm is known from DE 10 2011 003 212 A1. The rocker is designed with a side wall which, in a section adjacent to the center, has holes at which the rocker is held on a tube for bearing on the rocker shaft. To secure the rocker in the axial direction, a beading, caulking or welding is provided at the front end of the tube, or a snap ring groove connection to the tube is provided. In this refinement, complex assembly has a disadvantageous effect. [0003] Another possibility according to DE 10 2013 218 644 A1 is to mount the rocker arm directly pivotably on the shaft on its side wall, in the receiving opening, or as described for example in DE 10 2007 012 797 A1 In that way, the inside of the rocker arm is provided with a bearing sleeve for supporting o...
