Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an engine mount for an automobile, and more particularly to an engine mount for an automobile that also serves as a support member for a jack up.

As shown in FIG. 1, an automobile engine is placed vertically or horizontally in an engine compartment 2 and is supported by an engine mount 3 fixedly attached to the vehicle body 1. For example, there is one shown in FIG. This is done by attaching an engine mount front bracket 6 (hereinafter simply referred to as front bracket) to a front cross member 5 with bolts 11 and nuts 12, while attaching a darts cross member 8 welded to the lower end of a darts lower panel 13 of a vehicle body 1. engine mount rear bracket 9
(hereinafter referred to as a rear bracket), and support arms 7 and 10 are extended from these brackets 6 and 9 to the bottom of the engine 4 to support the engine 4 (for example, in 1979).

Type17 Rabbit Type53 Scirocco”).

However, in the case of such conventional automobile engine mounts, the engine mount 3,
In particular, the connecting portion of the front bracket 6 attached to the front cross member 5 simply consists of a flat flange that contacts the front cross member 5, and a portion of the weight of the engine 4 is supported by the connecting portion. It was just something I had learned to do. On the other hand, the side sill of the vehicle body (not shown)
A method was used in which a jack up point was installed in some parts of the car and the car body was raised at this position.
This method had the problem that the vehicle body could not be lifted to a sufficiently high position. This is because if the car is lifted high from one side in the horizontal direction, there is a risk that the car will tilt and fall.

Note that 45 in the figure supports the engine mount rear bracket 9 at the center and is fixed to the steering member 8 (not shown) on both sides.
46 and 47 are rain forces.

The present invention has been made in view of these conventional problems, and its purpose is to form a step-shaped attachment portion to a front cross member in the upper part of a front bracket in an automobile engine mount. The front bracket is attached to the side wall and lower wall of the front cross member, and a semi-cylindrical jack part is formed on the front bracket to protrude downward from the front cross member, so that the front bracket can be firmly attached to the front cross member and can also be used as an engine mount. The objective is to have both the function of a jack up point and the function of a jack up point, and to facilitate vehicle inspection and maintenance work by a jack up point.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 and FIG. 4 are diagrams showing an embodiment of the present invention. In the automobile engine mount according to this embodiment, a front bracket 16 is attached to a front cross member 5 in which a reinforcement 15 is disposed in a cross-sectional space by bolts 11 and nuts 12, while a dash cross member 8 and a mount bracket 45 are attached to the front cross member 5 by bolts 11 and nuts 12. The rear bracket 9 is attached to the rear bracket 9, and the support arms 7, 10 are extended from these brackets 16, 9 to the lower side of the engine 4 to support the engine 4, which is basically the same as the conventional example described above. It has a similar configuration. However, unlike in the past, the front bracket 16 has a pair of side bracket pieces 17 and 18 arranged on the left and right sides.
and these side bracket pieces 17, 18, and the side bracket pieces 17, 18
A center bracket part 19 is integrally welded to the center bracket part 19. Left side bracket piece 17
is formed by bending a plate material into a substantially U-shaped cross section, and has a side body portion 22 and flange portions 20 and 21 projecting outward at the upper and lower ends of the side body portion 22. In order to make the upper flange portion 20 come into contact with the front cross member 5 from the rear and bottom surfaces, the front end portion is formed into a stepped shape as an attachment portion to the front cross member 5, and the surfaces facing the front cross member 5 are each threaded. Through hole 23,2
4, and a connecting hole 25 for connecting the support arm 7 is formed near the rear end of the side body portion 22. The right side bracket piece 18 is also molded in the same manner as the left side bracket piece 17,
The side body portion 28 and the front end portion have an upper flange portion 26 and a flange portion 27 formed in a stepped shape, while the front end portion of the upper flange portion has screw holes 29,
30 is opened, and a connecting hole 31 is opened near the rear end of the side body portion 22. The center bracket piece 19 includes a jacking part 31 that protrudes downward and has a semi-cylindrical shape;
Side walls 32, 33 erected on both left and right sides of
and stepped flange portions 34, 35 provided at the upper edge portions of the side walls 32, 33 and protruding outwardly from the side walls 32, 33 on both the left and right sides are integrally molded. And left and right side bracket pieces 1
7, 18 and the center bracket piece 19, the flange part 34 is brought into contact with the flange part 20, the flange part 35 is brought into contact with the flange part 26, and the side body parts of the side bracket parts 17, 18 are 22, 28 to each side wall 32, 33 of the center bracket part 19, and spot weld 44 at this part.
It is integrated by applying Therefore, the flange parts 34 and 35 have the flange parts 20 and 2.
Screw holes 23, 24 and 29, 30 opened in 6
Corresponding screw holes 36, 37 and 38, 39 are formed. Screw holes 40, 41, 42, 43 are also formed in the positions of the front cross member 5 corresponding to these screw holes, and welds are formed on the back side of these screw holes 40, 41, 42, 43. Nut 12 is attached. The front bracket 16 is formed by assembling the left and right side bracket pieces 17, 18 and the center bracket piece 19.The front bracket 16 is made by assembling the left and right side bracket pieces 17, 18 and the center bracket piece 19. Installed and fixed.

If the front bracket 16 is attached to the front cross member 5 in this way, the side bracket piece 1 can be removed from the front cross member 5.
7 and 18 protrude rearward and support the engine 4 via the support arm 7, while these side bracket pieces 17 and 18 and the center bracket piece 1
Reinforce the front cross member 5 with 9 and
Further, a hemispherical jack abutting portion 31 protrudes from the lower surface of the front cross member 5 to enable jack up support. Therefore, the front cross member 5 can be jacked up at the center thereof while maintaining sufficient safety without particularly increasing the thickness of the front cross member 5.

As described above, according to the present invention, a step-like attachment part to the front cross member is formed at the upper part of the front bracket for the engine mount and is attached to the side wall and lower wall of the front cross member, and the front cross member is attached to the front bracket. Since a semi-cylindrical jack part is formed that protrudes downward from the member, the front bracket can be firmly fixed to the center part of the front cross member, and a jack up point can be formed to prevent the vehicle from moving forward. This makes it possible to jack up a car to a high position without fear of it falling over, making it easier to inspect and maintain each part of the car.
