Problems solved by technology

Due to space constraints inside the vehicle proximate the engine, there is inadequate room to enlarge the lifting bracket to the extent necessary to support the entire weight of the engine.
Moreover, the lifting bracket do not perform a function once the engine is located in the vehicle, so it is not desirable to increase the weight or cost of the vehicle by significantly increasing the size of the lifting bracket.

Embodiment Construction

[0018]The following describes a lift bracket on an internal combustion engine. The lift bracket is configured to support the entire weight of the internal combustion engine. The embodiments described herein use a dual lift bracket configuration for a single engine, but the advantages of the embodiments described herein can be realized in any lifting application, as will become evident to one having ordinary skill in the art.

[0019]A prior art engine 100, and a detail view of cylinder head 104, are shown in FIGS. 1 and 2 respectively. The engine 100 includes a crankcase 102. The engine 100 shown is of a “V” configuration having two banks. Each bank has a cylinder head 104 connected thereto. Each cylinder head 104 has a lower valve cover 106 connected to an upper valve cover 108 disposed thereon. Other components of the engine 100 are not shown in this figure for the sake of simplicity. A lift bracket 110 is connected onto each of the cylinder heads 104. Each lift bracket 110 forms an ...

Abstract

A lift bracket (300) includes a topmost portion (304) having an opening (302) arranged for engagement with an engagement portion of a lifting apparatus. The topmost portion (304) is substantially flat and defines a first plane (A-A). A base portion (320) of the lift bracket (300) has at least one fastener opening (322) for fastening the base portion to the engine. The base portion (320) also lies in the first plane (A-A). A yield structure (305) is disposed between the topmost portion (304) and the base portion (320), and includes a mid-portion (312) that defines at least one second plane (B-B) that is spaced and parallel to the first plane (A-A). When a tensile force is applied to the topmost portion (304), the yielding structure (305) yields, the topmost portion displaces away from the base portion (320), and the second plane (B-B) displaces towards the first plane (A-A).

Description

FIELD OF THE INVENTION[0001]This invention relates to components for internal combustion engines. More specifically, this invention is related to components used to connect an engine with a hoist for lifting of the engine.BACKGROUND OF THE INVENTION[0002]Internal combustion engine handling, both during engine and vehicle assembly operations and during service, is typically accomplished by use of a hoist or crane for lifting and moving the engine. Engines typically have lift brackets, which are components that are attached to the engine that have “eye” openings. A hook that is connected to a hoist engages the eye opening. The eye openings are typically disposed toward the top of an engine to facilitate connection of the hoist thereto for lifting of the engine.[0003]Typically, the hoist has chains connected to a lifting apparatus. On the distal end of the chain, there are typically hooks or other appropriate devices that engage the eye openings of the lift bracket on the engine. Two l...
