Problems solved by technology

Since there is a direct relationship between the bearing temperature and the service life of the bearing material, the local peak temperature essentially in the axial bearing center of the plain bearing limits the service life of the entire crankshaft bearing

Embodiment Construction

[0012] The invention here relates to a crankshaft bearing of a crankshaft of an internal combustion engine. Crankshaft bearings of this type are used to mount and support a crankshaft in a cylinder crankcase of an internal combustion engine, wherein the crankshaft bearing comprises a sliding bearing which generally consists of a plurality of bearing shells, namely an upper bearing shell and a lower bearing shell. These bushes fit into bores in the cylinder crankcase.

[0013] figure 1 A partial cross-section of a crankshaft bearing of a crankshaft (not shown) is shown in a very simplified manner, with a sectional direction in the axial direction of the crankshaft bearing, wherein in figure 1 A cross section of the bearing shell 10 , ie the lower bearing shell 10 of the crankshaft bearing, and a section of the crankcase 11 of the cylinder of the internal combustion engine adjoining the lower bearing shell 10 are shown in . exist figure 1 The lower bearing shell 10 , shown in...

Abstract

Crankshaft bearing of a crankshaft of an internal combustion engine, having a plain bearing formed by bearing shells, wherein the bearing shell (10) adjoins the cylinder crankcase (11) of the internal combustion engine via the bearing shell rear face (13) and adjoins the bearing shell to be supported via the bearing shell running surface (12) Crankshaft, wherein either the bearing pad running surface (12) or the bearing pad back face (13) or the surface (14) of the cylinder crankcase (11) adjoining the bearing pad rear face (13) has a concave contour.

Description

technical field [0001] The invention relates to a crankshaft bearing for a crankshaft of an internal combustion engine. Background technique [0002] The crankshaft bearing of the crankshaft is often also referred to as the main bearing and serves for supporting and supporting the crankshaft in the cylinder crankcase of the internal combustion engine. Crankshaft bearings generally consist of plain bearings consisting of several bearing shells, which are accommodated in the base bore of the cylinder crankcase. The base hole of the cylinder crankcase is lined with the bearing shell of the sliding bearing. The base hole is generally formed by a so-called bearing seat and a so-called bearing cover. The bearing seat is part of the cylinder crankcase, and the bearing cover is also a part of the cylinder crankcase. . The plain bearings of this crankshaft bearing are oil-lubricated in order to ensure the least possible wear of the crankshaft bearing. [0003] In conventional cran...
