Problems solved by technology

Although it would be conceivable to manufacture components and systems of this type from cast iron in a manner corresponding to the material of the camshaft, in order to prevent a very wide variety of materials from having different coefficients of expansion, cast iron components have disadvantages, in particular cast iron components have too high weight, and thus runs counter to the desire of the motor vehicle industry towards reduced weight vehicle components and vehicles

Embodiment Construction

[0023] figure 1 A cross-sectional view of a detail of an embodiment, in particular a first embodiment, of a camshaft segment 1 according to the invention is schematically shown. The camshaft section 1 has in particular a camshaft 2 with a shaft element 3 and a cam element 4 fixedly connected to the shaft element 3 for rotation with the shaft element 3 . The shaft element 3 is advantageously a hollow shaft or has at least one cavity extending at least partially in the axial direction of the shaft element 3 , that is to say along the longitudinal axis L of the shaft element 3 . The camshaft bearing 5 serves to mount the camshaft 2 , in particular the shaft element 3 of the camshaft 2 . The camshaft bearing 5 is advantageously a constituent part of the camshaft section 1 and has a reduction element 10 which is completely enclosed by the material of the camshaft bearing 5 and which according to the finished camshaft bearing 5 at least partially surrounds the shaft in the circumfe...

Abstract

The present invention relates to a camshaft segment with at least one camshaft having a shaft element and having a cam element, and to a camshaft bearing for the mounting of the camshaft at least in aradial or axial direction, wherein the camshaft bearing has at least one oil transfer element for the transfer of an oil medium to the camshaft, and the camshaft has at least one oil-guiding elementfor receiving and conducting the oil medium, and wherein the camshaft bearing has at least one reduction element, the material of which has a coefficient of expansion comparable to the coefficient ofexpansion of the material of the camshaft.

Description

technical field [0001] The invention relates to a camshaft segment with at least one camshaft having a shaft element and a cam element, and to a camshaft bearing for at least radial or Install the camshaft axially. Background technique [0002] Basically, it is known that a camshaft controls the gas exchange and thus the combustion within an internal combustion engine. The camshaft is driven by the crankshaft, so that the rotational movement of the camshaft is in a defined ratio to the rotational movement of the crankshaft and thus to the position of the piston in the cylinder. In order not to interrupt the operation of the camshaft, it is especially necessary to mount said camshaft correspondingly so as to prevent undesired movements in the axial and / or radial direction of the camshaft. Furthermore, it is basically known that camshafts are also used to transport control oil or lubricating oil for controlling the phase shifter, for example in the direction of the phase shi...
