AI Technical Summary
The existing commercial vehicle engine hoisting brackets are prone to interfere with the engine peripheral components during the lifting process, resulting in inconvenience in lifting and the structural design is difficult to meet the external dimension requirements of different cab assembly.
The movable hoist lugs and fixed brackets are combined with a hinged structure, and the flexible adjustment of the hoist lugs is achieved through the connectors and permanent magnets, ensuring safe clearance during engine lifting, and simplifying the production process through reinforcement ribs and screws to reduce costs.
The safe gap between the lifting lugs and peripheral components during engine lifting is achieved, which avoids interference problems, and at the same time improves the strength and service life of the lifting lugs and reduces production costs.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of engine hanging ears, and in particular relates to a commercial vehicle engine hanging bracket. Background Art
[0002] At present, with the rapid development of commercial vehicles, the same engine needs to be matched with cabs of different specifications to meet the universality of the engine assembly. The requirements for the design of the engine's external dimensions need to be further improved to match different cab assemblies. The design of the engine's peripheral components must not only meet the basic functional requirements, but also minimize the external dimensions to avoid interference with the chassis module. Figure 1 As shown, the engine lifting lug is used for engine lifting. The structure design of the lifting lug bracket 1 is too small and the gap between it and the peripheral parts of the engine 2 is small, so the hook interferes with the engine during lifting; after the structure design of the lifting lug bracket is enlarged, the gap between it and the peripheral parts of the chassis is further reduced, which is prone to interference. Summary of the invention
[0003] The utility model provides a commercial vehicle engine hanging bracket, aiming to solve the technical problem of interference in the existing hanging ear bracket.
[0004] In order to solve the above technical problems, the technical solution of the utility model is: a commercial vehicle engine hanging bracket, characterized in that it includes a movable lifting ear, a fixed bracket and a connecting piece, the movable lifting ear is used to connect the lifting equipment, the fixed connection is used to connect the engine parts, the adjacent ends of the movable lifting ear and the fixed bracket are connected by a connecting piece, and the movable lifting ear and the fixed bracket can both rotate around the connecting piece.
[0005] The above technical solution is further limited in that the structure of the movable lifting ear comprises an upper plate body, the upper end of the upper plate body is provided with a lifting hole, the lower side of the upper plate body extends symmetrically outward to form an upper boss, and the upper boss is provided with a pin hole.
[0006] The above technical solution is further improved in that a reinforcing rib is provided between the upper plate body and the upper boss.
[0007] The above technical solution is further limited in that the reinforcing ribs are screws.
[0008] The above technical solution is further defined as follows: the structure of the fixing bracket includes a lower plate body, a lower boss extends outward from the middle of the upper side of the lower plate body, a pin hole is provided in the lower boss, and a plurality of connection holes are distributed at the lower end of the lower plate body.
[0009] The above technical solution is further limited in that the connecting member is a pin.
[0010] The above technical solution is further improved in that an annular permanent magnet is provided on the connecting piece, and the permanent magnet is located between the upper boss of the movable lifting ear and the lower boss of the fixed bracket, and the upper boss and the lower boss are attracted to each other through the permanent magnet.
[0011] Beneficial effect: The movable lifting ear and the fixed bracket are hinged, and the position of the movable lifting ear is adjusted to meet the requirements of engine assembly lifting and the safety clearance between the engine hook and surrounding parts. At the same time, the folded state of the movable lifting ear can solve the problem of the engine lifting ear being too high and affecting the engine layout. BRIEF DESCRIPTION OF THE DRAWINGS
