Abstract
Description
[Technical field]
[0001] The present invention relates to an engine hanger. [Background technology]
[0002] Regarding engine hangers, for example, Patent Document 1 describes an engine hanger equipped with a hook portion for hanging on a hoist chain or the like. For example, when assembling an engine to a vehicle body, the engine is suspended from a hoist by the engine hanger and placed at the assembly position on the vehicle body. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2016-173095 A Summary of the Invention [Problem to be solved by the invention]
[0004] In the vehicle body, many parts are densely packed near the engine, so when removing the hoist from the hook portion, the worker must take great care not to contact the surrounding parts, which places a heavy burden on the worker.
[0005] The present invention has been made in consideration of the above problems, and has an object to provide an engine hanger that allows the hoist to be easily removed. [Means for solving the problem]
[0006] The engine hanger of the present invention has a hook portion that is engaged with an engaging member for suspending an engine, and a protrusion provided in a direction for removing the engaging member from the hook portion. Effect of the Invention
[0007] According to the present invention, the hoist can be easily removed from the engine hanger. [Brief description of the drawings]
[0008] [Figure 1] FIG. 1 is a schematic diagram showing an example of an engine suspended from a hoist. [Diagram 2] FIG. 2 is a cross-sectional view of the engagement jig taken along the line AA in FIG. [Diagram 3] FIG. 3 is a diagram showing an example of a state in which the engaging jig is removed from the hook portion. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Fig. 1 is a schematic diagram showing an example of an engine 3 suspended from a hoist 2. In Fig. 1, the X direction substantially coincides with the horizontal direction, the Y direction substantially coincides with the vertical direction, and the Z direction is perpendicular to the X direction and the Y direction.
[0010] For example, in a hybrid vehicle assembly plant, the engine 3 is suspended by a hoist 2 and placed at a predetermined position in the engine room R of the vehicle body. The engine 3 is the driving source of the hybrid vehicle, and is, for example, a gasoline engine. The engine 3 includes a cylinder head 30 at an upper part in the vertical direction and a cylinder block 31 at a lower part in the vertical direction. Furthermore, pipes 40, 41 are arranged on both sides of the cylinder head 30 in the X direction. The pipes 40, 41 are, for example, an intake passage for air and an exhaust passage for exhaust gas.
[0011] The hoist 2 includes a base 20, a set of chains 21, and a set of engagement jigs 23. An upper end of each chain 21 in the vertical direction is fixed to the base 20. Each chain 21 hangs down from the base 20, and an engagement jig 23 is connected to its lower end. The engagement jig 23 is an example of an engagement member for suspending the engine 3. The engagement jig 23 is shown by dotted lines so that the engagement state between the engine hangers 1a, 1b and the chains 21 can be visually confirmed.
[0012] The engine 3 is provided with a pair of engine hangers 1a, 1b for connection to the hoist 2. The engine hangers 1a, 1b are fixed to the ends of both side surfaces of the cylinder head 30 so as to be located near both ends of a substantially diagonal line on the top surface of the engine 3 when viewed from the front in the vertical direction.
[0013] The engine hangers 1a, 1b have an extension portion 10, a hook portion 11, a protrusion portion 12, and a fixing portion 13. The extension portion 10 is a metal member having a generally rectangular shape that extends in a generally vertical direction, and is provided with the hook portion 11 and the fixing portion 13 at its upper and lower ends, respectively.
[0014] The fixing portion 13 has a through hole H for fastening the engine hangers 1a, 1b to a predetermined position on the side surface of the cylinder head 30 with a bolt B. The hook portion 11 is engaged with an engaging jig 23. As a result, the engine 3 is connected to the chain 21 and suspended from the hoist 2.
[0015] The engagement jig 23 is, for example, a substantially rectangular parallelepiped member having a thickness in the Z direction. The engagement jig 23 has a connection hole 230 and an engagement shaft 231. The chain 21 is connected to the connection hole 230, and the hook portion 11 engages with the engagement shaft 231.
[0016] Fig. 2 is a cross-sectional view of engagement jig 23 taken along line AA in Fig. 1. Connection hole 230 penetrates engagement jig 23 in the Z direction at the vertical upper part. The lowermost ring 210 of chain 21 in the vertical direction is inserted into connection hole 230.
[0017] A pair of opposing plate portions 233a, 233b are provided at the bottom of the connection hole 230 to form a substantially U-shape. A space 232 is formed between the plate portions 233a, 233b. An engagement shaft 231 is provided within the space 232 to connect the plate portions 233a, 233b. The hook portion 11 is engaged by being caught on the engagement shaft 231 within the space 232. A protrusion 12 is provided below the hook portion 11 and the engagement shaft 231.
[0018] 1 again, the removal direction D is the direction in which the engaging jig 23 is removed from the hook portion 11. Since the hook portion 11 has a shape that opens downward in the vertical direction, the removal direction D faces substantially vertically downward. After the engine 3 is mounted in the engine room R, the engaging jig 23 is removed from the hook portion 11 by being pulled in the removal direction D. At this time, the chain 21 is bent so that the engaging jig 23 can be removed.
[0019] The protrusion 12 has a generally rectangular columnar shape and protrudes in the X direction from the extension portion 10, thereby being provided in the removal direction D of the engagement jig 23. In other words, the protrusion 12 protrudes from the extension portion 10 onto the removal path of the engagement jig 23. Therefore, when the engagement jig 23 is removed, the engagement shaft 231 abuts against the protrusion 12.
[0020] Fig. 3 is a diagram showing an example of a state in which the engaging jig 23 is removed from the hook portion 11. In Fig. 3, the same components as those in Fig. 1 are given the same reference numerals, and the description thereof will be omitted. For ease of explanation, the outer shape of the engaging shaft 231 is shown by a dotted line, and the engaging shaft 231 is shown by a solid line.
[0021] When the engaging jig 23 is pulled in the removal direction D, the engaging shaft 231 moves and comes into contact with the upper surface of the protrusion 12 (see symbol P). This prevents the engaging jig 23 from coming into contact with the piping 40 below the protrusion 12 (see symbol X). Note that other components around the engine 3 other than the piping 40 (e.g., plastic ducts, wire harnesses, etc.) are also similarly prevented from coming into contact with the engaging jig 23. After coming into contact with the protrusion 12, the engaging jig 23 is pulled horizontally and released from the engine hanger 1a (see symbol S).
[0022] Therefore, when removing the engagement jig 23 from the hook portion 11, the worker is less required to pay attention not to bring the engagement jig 23 into contact with components around the engine 3. For example, even if the worker pulls the engagement jig 23 forcefully in the removal direction D, the protrusion 12 prevents the engagement jig 23 from contacting the piping 40. Note that, since the other engine hanger 1b is also provided with a protrusion 12, contact between the engagement jig 23 and the piping 41 is suppressed in the same manner as described above.
[0023] Therefore, the engine hangers 1a and 1b reduce the burden on the worker and allow the hoist 2 to be easily removed. The protrusions 12 can protect the components around the engine 3 from certain components that are displaced due to a vehicle collision, as well as when the engaging jig 23 is removed. There are no limitations on the shape or protruding angle of the protrusions 12.
[0024] The above-described embodiment is a preferred example of the present invention, but the present invention is not limited to this embodiment and can be modified in various ways without departing from the scope of the present invention. [Explanation of symbols]
