Problems solved by technology

[0021] In most of the documents presented, the provided locking elements impair the life of the assembly because these are thin and may break, or they cannot even be produced due to the high flexibility of the elements
Other solutions such as welding and gluing are also used for fixing, but such solutions make the system very rigid without the benefit of the flange being flexible relative to the copper alloy bushing

Embodiment Construction

[0038]The present invention relates to a flanged copper alloy bushing 100 for use in an internal combustion engine, particularly a crankshaft. This use is due to the fact that when the vehicle is in motion or changing gears, the transmission remains connected to the electric motor by means of a clutch, which essentially uses the crankshaft as a point of support to facilitate the disengagement of the engine from the transmission to enable gear changes due to the vehicle Caused by depressing on the clutch. At this time, the crankshaft is subjected to a large axial stress, and the stress is reflected on the axial bearing, which is also called a flange.

[0039] The flanged copper alloy bushing 100 of the present invention is proposed for the perfect functioning of the movable parts, minimizing friction and ensuring movement with respect to transmitted forces.

[0040] However, before describing the flanged copper alloy bushing 100 of the present invention, it should be distingui...

Abstract

The present invention relates to a flanged bronze bushing, provided with at least one slide bearing (1) and at least one axial bearing (2) in the form of a flange; the slide bearing (1) comprising at least first (4) and second (4') recesses arranged in a side region (6); the axial bearing (2) comprising at least one deformable protrusion (3) arranged in first position (12), an adjacent space (5), a stress-alleviating region (7), a rigid protrusion (8) and a cooperating surface (10). The axial bearing (2) is capable of being integrated with the slide bearing (1) through association of the cooperating surface (10) of the deformable protrusion (3) with the first recess (4), the deformable protrusion (3) taking on a second position (12), which exhibits plastic deformation ([Delta]X) with respect to the first position (11); and through simultaneous association of the rigid protrusion (8) with the fixed recess (4').

Description

technical field [0001] The invention relates to a flanged copper alloy bush used on an internal combustion engine. The copper alloy bush is provided with a sliding bearing connected to an axial bearing by means of a plastically deformed fixing device. Background technique [0002] Diesel engines and otto (Otto) engines have to increase the axial load on the surface of the crank disk. As a result, the axial reaction force on the plain bearing using the flange will also experience increased load, and if the product does not have advanced characteristics, the product life will be impaired. [0003] The possibility of mounting different materials on plain and axial bearings facilitates their application and increases the service life of the components. The use of this type of product is influenced by the philosophy of companies that manufacture engines, who may choose to utilize copper alloy bushings with rigid flanges as one piece, and may also utilize flanged copper Thrust ...
