Abstract

PURPOSE:To improve workability in installation of partners between the engine side and the car body side by inserting the stud bolt of an auxiliary bracket on the car body side into the through hole of the bracket on the engine side. CONSTITUTION:An auxiliary bracket 10 is connected with the shaft 5 of a mount main body 6, and a stud bolt 11 is fixed underneath the auxiliary bracket 10. The outer circumferential section of a cylindrical body 3 is therefore fixed onto the car body side in a state that the auxiliary bracket 10 is connected with the shaft 5 of the mount main body 6, and the stud bolt 11 is fixed on the auxiliary bracket 10. Under which situation, the engine 1 is lifted from the down-side of the car body so that the stud bolt 11 of the auxliary bracket 10 is inserted into the through hole 12 of a bracket 9 for positioning the engine 1 relatively against the car body while a nut is threadedly engaged with the stud bolt 11 so as to let the auxiliary bracket 10 be fastened together with the bracket 9. This constitution enables the three parties composed of the engine 1, the mount main body 6 and the car body to be aligned with ease, thereby improving workability in assembly.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an engine mount device for elastically supporting an engine on the body of an automobile.

(Prior Art) Generally, when an engine is mounted on a vehicle body, the engine is attached to the vehicle body via a plurality of engine mount devices. The structure of the engine mount device and the method of mounting it on the vehicle body vary depending on the mounting position and the structure of the engine itself, but as shown in Figures 3 and 4.
As shown in the figure, a portion of the engine l on the rear side of the vehicle body may be supported by a member 2 on the vehicle body side. In the engine mount device used here, a rubber material 4 is installed inside a cylinder 3, and a mount body 6 is formed by passing a shaft 5 through the rubber material 4.
The shaft 5 of the mount body 6 is fixed to the engine l via the bracket 7 by bolting or the like.

The arm portion 8 attached to the outer peripheral surface of the cylinder 3 is fixed to the member 2 on the vehicle body side by tightening bolts or the like.

(Problem to be Solved by the Invention) However, in the conventional engine mount device described above, bolts must be tightened from the horizontal direction due to the shape of the parts when mounting the engine 1 side and the vehicle body side. There was a problem in that the work of fixing the main body 6 and the member 2 on the vehicle body side became extremely difficult. This is because the operator has to position the mount body 6, which has been attached to the engine 1 side, and the vehicle body side member 2 in advance in the space in the engine room sandwiched between the engine 1 and the vehicle body side member 2. This is a major factor.

An object of the present invention is to provide an engine mount device that allows the engine, the mount body, and the main part of the vehicle body to be easily aligned when mounting the engine on the vehicle body, and improves work efficiency during assembly. It is something.

(Means for Solving the Problem) The present invention, as a means for solving the above-mentioned problem H,
Put a rubber material 4 inside the cylinder 3 and use the rubber material 4! In the engine mount device, a mount body 6 is formed through 115, and the outer peripheral part of the cylindrical body 3 is fixed to the vehicle body side, while the shaft 5 is supported by a bracket 9 and the bracket 9 is fixed to the engine 1 side. An auxiliary bracket lO is connected to the shaft 5, a stud bolt 11 extending downward is attached to the auxiliary bracket lO, a through hole 12 for inserting the stud bolt 11 is provided in the bracket 9, and the stud bolt 11 is inserted through the through hole 12. The auxiliary bracket 10 and the bracket 9 are inserted into the hole 12 and fastened together.

(Function) With this configuration, the engine 1 (11) can be assembled to the vehicle body in the following manner.

First, the auxiliary bracket 10 is connected to the shaft 5 of the mount body 6, and the outer periphery of the cylinder 3 is fixed to the vehicle body with the stud bolt 11 attached to the auxiliary bracket IO. A bracket 9 is fixed to the side. In this state, lift the engine I from below the vehicle body, insert the stud bolt 11 of the auxiliary bracket IO into the through hole 12 of the bracket 9, and position the engine I and the vehicle body relative to each other. In this state, a nut is screwed onto the stud bolt 11 to fix the auxiliary bracket 10 and the bracket 9 together.

(Example) Hereinafter, an example of the present invention will be described in detail based on FIGS. 1 and 2. Note that the same reference numerals are used for the same parts as in the conventional technology shown in FIGS. 3 and 4.

6 is a mount body, and this mount body 6 has a cylindrical body 3 with a rubber material 4 inside, and a bolt 1 in the center of this rubber material.
The shaft 5 of No. 3 is loosely inserted. A pair of arm portions 8 are formed on the outer periphery of the cylinder 3, and each arm portion 8
is attached to the member 2 on the vehicle body side via bolts 14. The bolt 13 loosely inserted into the rubber material 4 is supported by a bracket 9 on the engine 1 side, which will be described later. Therefore, the mount body 6 absorbs vibrations transmitted to the shaft 5 and the cylinder body 3 using the rubber material 4.

10 is an auxiliary bracket, and this auxiliary bracket 10
are both side walls 15a of the substrate 15 having a U-shaped cross section.
An overhanging member 16 is welded to the outer surface of each. A hole 15a is bored in each of the overhanging members 16, and a nut 7 is fixed so as to be concentric with the hole 15a. and,
The base end portion of the stud bolt 11 communicating with the hole f6a is screwed into the nut 17. Furthermore, holes 15b and 16b for loosely inserting the shafts 5 of the bolts 13 are formed at predetermined positions in the side walls 15a of the substrate 15 and the respective overhanging members 16 superimposed thereon.

On the other hand, the bracket 9 has a plurality of holes 18a formed in its base 18, and bolts 19 are inserted into the holes 18a to be bolted to the engine 1. Also, base 1
A pair of flanges 20 extend in a U-shape from the upper end of the bolt 8, and a through hole 12 into which the tip of the stud bolt 11 is inserted is formed in each flange 20.

Incidentally, the reference numeral 21 in the figure indicates a washer, and the reference numeral 22 indicates a nut.

The engine mount device configured as described above is assembled to the engine 1 and the vehicle body side member 2 in the following manner.

First, the mount body 6 is interposed between the side walls 15ajSa of the auxiliary brackets 1 to 10, the shaft 5 of the bolt 13 is passed through the side wall 15a and the mount body 6, and in this state, the nut is attached to the tip of the bolt 13 via the washer 2I. Screw on 22. Then, the base end portions of the stud bolts 11 are screwed into both overhanging portions 16 of the auxiliary bracket 10, and the arm portion 8 of the mount body 6 is fixed to the member 2 on the vehicle body side using the bolts 2. At this time, the stud bolt 11 attached to the auxiliary bracket 10
is extended downward. On the other hand, the bracket 9 is fixed to a predetermined portion of the engine 1 with bolts 19.

Subsequently, in this state, the engine 1 is lifted from below the vehicle body, and the tip of the stud bolt 11 supported on the vehicle body side is inserted into the through hole 12 of the bracket 9 attached to the engine 1. At this time, a portion of the auxiliary bracket 10 below the projecting portion 16 is inserted between a pair of flanges 20 and 20 of the bracket 9 extending in a U-shape. Then, when the lower surface of the overhanging portion 16 and the upper surface of the flange 20 come into contact, a washer 21 is attached to the tip of the stud bolt 11.
and the nut 22, and then tighten the nut 22 from below the vehicle body. When the nut 22 has been tightened, the assembly of the engine mount device according to the present invention is completed.

(Effects of the Invention) As explained above, according to the present invention, when mounting an engine on a vehicle body, it is necessary to lift the engine from below and insert the stud bolt of the auxiliary bracket on the vehicle body side into the through hole of the bracket on the engine side. Since the engine, the mount body, and the main part of the vehicle body can be easily positioned, the workability of assembling the engine side and the vehicle body side components is greatly improved.
