Description

Car engine mounter

The present invention relates to an engine mounter of an automobile, and more particularly, to an engine mounter of an automobile for reducing vibration and noise caused by driving of an engine.

In general, the method of supporting and mounting the engine of a vehicle is designed according to the structure and type of the engine, the structure and type of the chassis, the body, and the like to reduce the vibration and to withstand the weight of the engine. Will have

Currently, the mounting method of the engine currently adopted is a four-point or three-point support method, and a torque roll shaft support method is also adopted for passenger cars.

In the above-described torque roll shaft support method, the engine mounting method defines the front support part of the engine at the center and the rear support part of the engine near the center so that the engine mounting point is closer to the center of the engine than the three- or four-point support method. It is located in the high place.

In the above four-point engine mounting method, the front support part is supported at the timing gear case or the front end of the engine, and the rear support part is supported at the rear end and both sides of the clutch housing or the transmission case, respectively.

On the other hand, the engine that is supported and fixed in accordance with the support method as described above is mounted on the vehicle body 6 with the engine mount, that is, the insulator 5 is interposed, the transmission case 4 side and the vehicle body 6 connected to the engine The insulator 5 made of a rubber member is arranged between the brackets 8 and 10 made of metal, which is fixedly disposed on the side thereof, so that the insulator 5 is used to drive the engine between the brackets 8 and 10. The vibration caused by the vibration or the driving of the vehicle is absorbed.

In addition, the insulator 5 as described above has an inner tube 12 having both ends coupled to one side of the bracket 8 on the transmission case 4 side through the shaft center thereof, and an outer circumferential surface thereof is the vehicle body ( 6) wrapped and restrained by the bracket 10 on the side.

In addition, a plurality of slots 13 may be formed in the insulator 5 in order to increase the absorption limit of vibration force to the peripheral portion of the inner tube 12.

However, the conventional engine mount as described above is difficult to assemble because the inner tube is coupled in the state passing through the center of the insulator, and also has a structure in which the center of the insulator is fixed in the inner tube so that the limit of absorption of vibration force is limited. There was a disadvantage that can not be increased.

Therefore, the vibration force according to the driving and operation of the engine and the transmission is transmitted to the vehicle body, which not only worsens the ride comfort of the vehicle, but also prevents generation of noise caused by vibration.

The present invention has been made to solve the above-mentioned disadvantages, the object of the present invention to change the center of the insulator to overcome the limitation of absorbing vibration force transmitted to the vehicle body, accordingly the ride comfort of the vehicle In addition, the present invention provides an engine mounter for a vehicle that can improve noise reduction and prevent noise generated by vibration.

6: body 8: upper bracket

10: lower bracket

In order to realize this, the present invention arranges an insulator made of a rubber member between a metal bracket fixedly disposed on the engine side and the vehicle body side, which causes the insulator to be generated due to vibration of the engine or driving of the vehicle between the brackets. In the engine mounter of a vehicle to absorb the vibration force, the insulator has an opening in the longitudinal direction of the circumferential surface so that the inner tube of the bracket on the transmission case side can be fitted in the longitudinal direction, the inner tube It is to provide an engine mounter of a vehicle, characterized in that the contact surface portion is formed in a waveform.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, and the same reference numerals as those of the conventional drawings will be given to the same parts that are overlapped with the conventional engine mounter.

One embodiment of the present invention relates to an engine mounter of a motor vehicle for mounting the engine to the vehicle body 6 as in FIG. 2, and more particularly to an engine mounter arranged to the side of the transmission case 4.

As described above, the engine mounter arranges the insulator 5 made of a rubber member between the metal brackets 8 and 10 fixedly disposed on the engine side and the vehicle body 6 side. The brackets 8 and 10 are configured to absorb vibrations generated by driving of the engine or vibrations generated by driving of the vehicle.

On the other hand, the insulator 5 has an opening 14 formed in the longitudinal direction of the circumferential surface so that the inner tube 12 of the bracket 8 on the transmission case 4 side can be fitted in the longitudinal direction. have. (See Fig. 3)

In addition, the inner surface of the insulator 5 in contact with the inner tube 12 is formed into a waveform having a peak portion 20 so that the center of the insulator 5 is changed in accordance with the elastic flow of the peak portion 20 so that the vibration force is reduced. The absorption limit can be amplified.

As described above, the engine mounter of the vehicle according to the present invention may change the center of the insulator, thereby overcoming the limitation of absorbing vibration force transmitted to the vehicle body, thereby improving the riding comfort of the vehicle and In addition to preventing the occurrence of noise, there is an advantage that can be expected to improve the workability and productivity by simplifying the assembly work.
