Description

[Detailed description of the invention] This invention is based on the idea that when the engine is suspended by a lifting device and attached to or removed from the car body, the engine is tilted and the engine's auxiliary equipment is interposed between the engine and the car body. This invention relates to an engagement structure between an engine and a vehicle body that prevents the engine from colliding with the equipment or members that are being used and damaging those equipment or members.

For example, in the F/R type car (front engine rear drive type) shown in Fig. 5, the car body 20
When removing the engine 21 mounted on the vehicle body 20 from the vehicle body 20, a plurality of locking hooks provided on a lifting device (not shown) are connected to a plurality of engine hangers (not shown) attached to the outer surface of the engine 21. ), and the engine 21 is suspended.

However, engine 21 and transmission 2
The center of gravity of the engine 2 is located somewhat rearward than the longitudinal center of the engine 21.
1 is inclined downwardly as shown by the imaginary line B, and the rear part 21A of the engine 21 is a vehicle body member,
In other words, there is a risk of collision with the dash panel 22. In this way, the rear part 21A of the engine 21 collides with the dash panel 22, causing the engine 21 to collide with the dash panel 22.
The first auxiliary equipment (for example, an air cleaner) is attached to the front of the dash panel 22 and is interposed between the rear part 21A of the engine 21 and the dash panel 22, such as harnesses, piping, a master cylinder (not shown), and other equipment. The problem arises that the parts collide and are damaged.

In addition, in Japanese Utility Model Publication No. 54-18730, in order to avoid increasing the degree of injury to occupants due to the engine rushing into the interior of the vehicle in the event of a frontal collision, the rear part of the engine is actively moved during a collision. Although an engine dropping structure configured to allow the engine to drop downward is disclosed, there is no means to solve the above-mentioned conventional problem caused by the engine tilting backwards and downwards when the engine is attached to and removed from the vehicle body. Not disclosed.

This idea was created in view of the conventional problems mentioned above, and when installing and removing the engine from the vehicle body, even if the engine is tilted backwards and downwards, the engine's auxiliary equipment is interposed between the engine and the dash panel. The purpose of the present invention is to provide an engagement structure between an engine and a vehicle body that can prevent damage to equipment and members.

Embodiments of this invention will be described below with reference to the drawings.

FIG. 1 is a side view showing an embodiment in which the engine-vehicle body engagement structure according to the present invention is applied to an F/R type vehicle. In the figure, 1 is an engine, 2 is a transmission case, and 3 is a side view. A dash panel is shown, and the dash panel 3 partitions an engine room 5 and a vehicle interior 6 of a vehicle body 4.

The engine 1 is attached to the vehicle body 4 in an engine room 5 via a plurality of engine mounts (not shown), and the transmission case 2 is located in a tunnel portion 8 continuous to the rear of the lower part of the dash panel 3. And the rear part 1A of engine 1
An engine hanger 9 is attached to the engine hanger 9.

In addition to the engine hanger 9, a plurality of (for example, 2 to 3) engine hangers (not shown) are attached to the engine 1, and locking hooks of a lifting device (not shown) are attached to these engine hangers. By aligning them together, the engine 1 is suspended.

As shown in FIGS. 2 and 3, the engine hanger 9 is formed by pressing a steel plate, for example, and has a locking piece 9b extending to one side of the base 9a. . And the base 9
At the top of a, there is a stopper part 9 that protrudes backward in a key shape.
c is integrally molded, and an elastic member 9d made of rubber or the like is fixed by baking to the rear surface of the stopper portion 9c. Furthermore, a through hole 9e is formed in the base 9a, through which the shaft of a tightening member 10 (FIG. 1) such as a bolt passes. Therefore, as is clear from FIG. 1, the engine hanger 9 has its base portion 9a in contact with the rear portion 1A of the engine 1, and the shaft portion of the tightening member 10 is inserted into the through hole 9e (FIG. 3). It is attached to the rear part 1A of the engine 1 by penetrating through it, screwing the shaft part onto the engine 1 and tightening it, and the stopper part 9c protrudes toward the dash panel 3 side.

In FIG. 1, a receiving portion 3A protruding toward the engine 1 is formed at a position on the dash panel 3 facing the stopper portion 9c of the engine hanger 9, and a reinforcing member 11 is attached to the rear side of the receiving portion 3A. ing.

In the above configuration, when removing the engine 1 mounted on the vehicle body 4, for example, a plurality of locking hooks provided on a lifting device (not shown) are connected to the engine hanger 9 attached to the outer surface of the engine 1. This is done by engaging the locking piece 9b (FIG. 2) of the engine 1 and the locking piece of another engine hanger (not shown), and moving the engine 1 in the direction of arrow A in FIG. 1 while suspending the engine 1. Ru. In this case, the centers of gravity of the engine 1 and the transmission 2 are located somewhat rearward of the center in the longitudinal direction of the engine 1, so that the engine 1 tilts backwards and downwards. As shown by line D, the elastic member 9d which is sewn and fixed to the rear surface of the stopper part 9c of the engine hanger 9 and the receiving part 3A of the dash panel 3 come into contact with each other. Therefore, the rear part 1A of the engine 1 and the dash panel 3 do not collide directly, and there is a large gap L between the rear part 1A and the dash panel 3 (this gap L is set so that the engine accessories do not collide with the harness etc. ) can be ensured, so that the auxiliary equipment of the engine 1 and the harness, piping, master cylinder, etc. installed on the front of the dash panel 3 and interposed between the rear part 1A of the engine 1 and the dash panel 3 can be secured. Equipment and components (not shown) are not damaged.

Although the above embodiment describes the case where the engine 1 is removed from the vehicle body 4, similar effects can be obtained even when the transmission case 2 is removed from the engine 1. Also, F.
Although this is explained using an example applied to an R-type car,
Naturally, the present invention can also be applied to other types of automobiles such as F/F type cars and R/R type cars.

Furthermore, since the elastic member 9d is fixed and baked to the rear surface of the stopper part 9c of the engine hanger 9, the shock when the cushion panel 3 comes into contact with the receiving part 3A can be alleviated by the cushioning action of the elastic member 9d. , the elastic member 9d is not necessarily required. In addition, the receiving part 3 of the dash panel 3
Although the explanation is given using an example in which the reinforcing member 11 is attached to the rear side of A, since the receiving part 3A is formed to protrude toward the engine 1 side, it has relatively high rigidity, and therefore the reinforcing member 11 is not necessary. Sushi is not necessary either.

As explained above, according to this invention, the engine hanger attached to the rear part of the engine is integrally molded with a stopper part that protrudes toward the dash panel, and a receptacle that protrudes toward the engine is provided at a position on the dash panel opposite to the stopper part. Because the engine is attached to and removed from the car body, even if the engine is tilted backwards and downwards, the engine auxiliaries will not be able to remove any equipment or parts that are interposed between the engine and the dash panel. This has the advantage of preventing damage.
