Embodiment Construction

[0021] The following describes an embodiment of the present invention with reference to the accompanying drawings.

[0022] figure 1 It is a top view of a partition to be fastened. figure 2 for fastening time figure 1 A cross-sectional view of the separator taken along line A-A. Figure 3 shows along the figure 1 The cross-sectional view taken along the line B-B in the middle, and Figure 4 showing along figure 1 A cross-sectional view taken along line C-C.

[0023] The separator 10 is used in a vehicle engine and is therefore a die-cast relatively thin metal plate. Such as figure 2 As shown, the separator plate 10 is disposed between the crankshaft 40 and the oil pan 50 . The partition 10 includes an integral portion 12 and flanges 14a and 14b protruding on each side. A notch 28 for receiving a screen (not shown) is provided in one corner of the partition.

[0024] As shown in FIGS. 3 and 4 , the body portion 12 has a downwardly protruding arcuate cross-section. T...

Abstract

A baffle plate is arranged between a crankshaft axially supported in a freely rotating manner by a cylinder block and a bearing cap and an oil pan storing lubricating oil supplied to each part of a vehicle engine. The baffle plate is fastened to the bearing cap using parent bolts for fastening the bearing cap and the cylinder block through screwing from the bottom surface of the bearing cap.

Description

[0001] Cross References to Related Applications [0002] Japanese Priority Patent Application No-2003-360564 on which this patent application is based is incorporated herein by reference. technical field [0003] The present invention relates to an oil pan spacer (baffle) fastening jig and fastening method for arranging a spacer between a crankshaft and an oil pan storing lubricating oil supplied to various parts of a vehicle engine. Background technique [0004] Lubricating oil supplied to components in a vehicle engine is stored in an oil pan provided at the bottom of the engine. The stored lubricating oil is sucked by an oil pump, filtered and purified by an oil filter, and supplied to the engine again. A plate called a partition is placed between the oil pan and the crankshaft. The partition is provided to prevent stored lubricating oil from accumulating so as to lean toward the (crankshaft) side. Oil drip holes are usually formed on the separator to drain lubricating...
