Description

Technical Field

[0001] The utility model relates to the technical field of engine lifting eyes and lifting, in particular to an engine lifting eye device. Background Art

[0002] When the engine is matched with the customer's new car model, because the cab is shorter, the rear suspension beam of the cab interferes with the rear lifting ear of the engine. The engine lifting ear is required to be designed with a more compact appearance, reliably lift the engine, and maintain a gap of more than 30mm with the rear suspension beam of the cab in a static state.

[0003] like Figure 2 As shown, the defects of the prior art are:

[0004] 1. In order to meet the design requirements of the engine lifting lug, the shape structure and installation position of the lifting lug are usually redesigned, which requires changing the engine cylinder block or cylinder head, which in turn greatly affects the force of the lifting lug, bolt connection, and engine lifting inclination angle, making implementation difficult and time-consuming.

[0005] 2. In the existing solution, the rear suspension beam of the cab is moved toward the rear end of the vehicle, keeping the engine hanging ear unchanged. The first gap between the rear suspension beam of the cab and the engine hanging ear in a static state is 18 mm, and the second gap between the rear suspension beam of the cab and the engine hanging ear in a static state is 24.86 mm. As a result, in the moving condition of the vehicle, dynamic interference between the hanging ear and the rear suspension beam of the cab will be caused, thereby affecting the strength and connection tightness of the hanging ear, posing a greater safety risk. Summary of the invention

[0006] In view of the above-mentioned problems, the utility model provides an engine lifting ear device, the purpose of which is to be able to bear the engine lifting weight to ensure good reliability and meet the clearance requirements with the parts of the whole vehicle when the rear suspension beam of the vehicle cab is moved backward; at the same time, the ear installation position, bolt and lifting hole positions are kept unchanged, there is no need to develop a cylinder head or a hook, the number of parts is reduced, and the assembly efficiency is improved.

[0007] In order to solve the above problems, the technical solution provided by the utility model is:

[0008] The engine lifting eye device comprises a lifting eye body, a first reinforcing rib, and a first avoidance structure, wherein:

[0010] A cylinder head connection hole is provided at the bottom of the lifting ear body; the position of the cylinder head connection hole matches the corresponding installation position of the engine cylinder head; the lifting ear body is bolted to the engine cylinder head through the cylinder head connection hole;

[0011] A connection hole for a lifting hook is provided on the top of the lifting ear body; the lifting hook passes through the connection hole of the lifting hook and is hooked to the lifting ear body;

[0012] The first avoidance structure is a polygonal sheet structure; the connection between the top of the first avoidance structure and the top of the lifting ear body is in an arc shape;

[0013] The first reinforcing rib is a sheet-like structure with a curved surface;

[0014] The first reinforcing rib comprises a second avoidance structure and a reinforcing rib body;

[0015] The second avoidance structure is arranged at the top of the reinforcing rib; and the connection between the second avoidance structure and the top of the lifting ear body is in an arc shape.

[0016] Preferably, the angle between the surface of the first avoidance structure and the surface of the lifting ear body is a straight angle.

[0017] Preferably, there are four cylinder head connecting holes.

[0018] Preferably, the connection hole of the lifting hook is a waist-shaped hole; the size of the connection hole of the lifting hook is 55×40 mm.

[0019] Preferably, the length of the reinforcing rib body is 98 mm.

[0020] Preferably, the minimum distance between the center of the arc edge of the second avoidance structure and the cylinder head connecting hole is 98 mm.

[0021] Preferably, the engine lifting eye device is made of DL700 material.

[0022] Preferably, the lifting ear body is provided with a second reinforcing rib protruding upward.

[0023] Compared with the prior art, the utility model has the following advantages:

[0024] 1. As the lifting lug is made of DL700 material, it has higher tensile strength and yield strength, thus it can bear the weight of engine lifting and ensure good reliability.

[0025] 2. Due to the avoidance structure design adopted by the lifting lug, the lifting lug can avoid the vehicle parts, thereby meeting the clearance requirements with the vehicle parts.

[0026] 3. Since the lifting lug does not change the waist-shaped hole for connecting the lifting hook and the connection hole with the engine cylinder head, the installation position and bolts of the lifting lug remain unchanged, and there is no need to develop the cylinder head and lifting hook, which reduces the number of parts and improves assembly efficiency.
