Abstract

The present invention is intended for fixing the engine mounting bracket of an automobile, wherein the first, second and fourth engine brackets are installed in the transmission of the engine assembly, and the third engine brackets are installed in the engine by fastening means such as bolts. In the fixed structure of the engine mounting bracket of an automobile, the third engine bracket is provided on the front side of the engine so as to be close to the rotation center axis of the engine. According to the present invention, since the third and fourth engine brackets of the engine assembly are disposed in close proximity to the rotational center axis of the engine, not only the idle vibration of the engine can be improved but also the acceleration / deceleration vibration and the impact are improved. It is possible to improve the ride comfort.

Description

Engine mounting bracket fixing structure of automobile

The present invention relates to a fixed structure of the engine mounting bracket of an automobile. In particular, among the various brackets for mounting the engine assembly to the mounting of the vehicle body, the third and fourth brackets are installed close to the torque roll shaft and the idle vibration of the engine is achieved. And an engine mounting bracket fixing structure for a vehicle to improve acceleration / deceleration shock.

In general, when mounting the engine assembly, it is important to ensure that vibrations and noise of the engine are not transmitted directly to the vehicle body. To this end, an engine assembly is mounted to a vehicle body using a dustproof body called an engine mounting.

The above-mentioned engine mounting has a structure in which pipes are respectively installed inside and outside of the anti-vibration rubber, and a separate outer bracket is connected to the outer pipe so that the outer bracket and the engine bracket are connected and mounted. A separate fixing member is interposed to connect the vehicle body bracket.

Here, as shown in FIG. 1, the engine bracket is generally attached to the transmission 1 of the engine assembly with the first, second and fourth brackets 2, 3, 4 attached thereto, and the engine of the engine assembly. The third bracket 6 is attached to (5).

As described above, several engine brackets (2), (3), (4) and (6) attached to the engine assembly are connected to the mounting of the vehicle body to mount and support the engine. In this way, when the engine mounting is used, Since vibrations and noises generated from the engine are absorbed and buffered in the anti-vibration rubber of the engine mounting, the vehicle is not directly transmitted to the vehicle body, thereby improving the riding comfort.

However, in the engine mounting bracket assembly structure of a general automobile as described above, the third bracket of the several engine mounting brackets is installed at the rear portion of the engine, that is, the intake manifold side, and is indicated by a dashed-dotted line in the drawing. There was a problem that the engine is not able to effectively catch the vibration and acceleration, deceleration vibration / impact of the engine is off one rotational axis. Generally, the third and fourth brackets of several engine brackets are known to be advantageous for idle vibration, acceleration, and deceleration shock when they are close to the central axis of rotation. However, in the conventional structure, the third bracket is located at the rear of the engine. Limitations have occurred in damping vibrations and shocks.

The present invention is conceived in view of the above, by installing the third engine bracket close to the center of rotation of the engine engine mounting of the vehicle that can improve the idle vibration and acceleration, deceleration vibration / impact of the engine The purpose is to provide a bracket mounting structure.

An object of the present invention as described above, the engine mounting of the vehicle is provided by the first, second and fourth engine brackets in the transmission of the engine assembly, the third engine brackets in the engine by a fastening means such as bolts and the like. In the bracket mounting structure, the third engine bracket is achieved by providing an engine mounting bracket mounting structure for a vehicle, characterized in that it is installed on the front side of the engine so as to be close to the axis of rotation center of the engine.

According to the present invention, since the third and fourth engine brackets of the engine assembly are disposed in close proximity to the rotational center axis of the engine, not only the idle vibration of the engine can be improved but also the acceleration / deceleration vibration and the impact are improved. It is possible to improve the ride comfort.

EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a schematic view showing an engine mounting bracket fixing structure of a vehicle according to the present invention. As shown in the drawing, the present invention provides a first, second and fourth engine bra to the transmission 1 of the engine assembly. The kits 2, 3 and 4 are installed by fastening means such as bolts, and the third engine bracket 6 is located on the front of the engine 5, that is, on the pulley side. It is arrange | positioned so that the rotation center axis | shaft as shown in FIG.

That is, the present invention improves the fact that the conventional third engine bracket 6 is installed at the rear of the engine so that it is not separated from the central axis of rotation by a long distance and effectively catches the vibration and impact of the engine when the engine is idle or accelerated or decelerated. In order to solve the drawbacks of the prior art by moving the third engine bracket to the front of the engine close to the rotation center axis.

As described above, the engine mounting bracket assembly structure of the vehicle according to the present invention improves idle vibration of the engine since the third and fourth engine brackets of the engine assembly are disposed to be disposed close to the rotational center axis of the engine. Not only can this be achieved, but the deceleration vibration and shock can be improved, and the riding comfort can be improved.

In the above has been shown and described with respect to one embodiment for implementing the engine mounting bracket kit fixing structure of the vehicle according to the present invention, the present invention is not limited to the above embodiment, this invention claimed in the claims below Various changes can be made by those skilled in the art without departing from the gist of the present invention.

Claims (1)

In the engine assembly bracket structure of a motor vehicle, the first, second and fourth engine brackets are installed in the transmission of the engine assembly, and the third engine brackets are installed in the engine by fastening means such as bolts. 3 engine bracket is fixed to the engine mounting bracket of the vehicle, characterized in that installed on the front side of the engine to be close to the axis of rotation of the engine.
