Description

Engine Mount Exhaust Structure of Four Wheel Drive Vehicle

The present invention relates to an engine mount displacement structure of a four-wheel drive vehicle.

According to the engine mounting method of the four-wheel drive vehicle, the front part of the side of the engine body, which is one side of the engine unit mounted in the engine room in the transverse direction, and the three parts of the front part and the rear part of the transmission part of the other part of the engine unit The so-called three-point mount system, which is coupled to the left and right front side members through the engine mount and is supported, is used.However, in this three-point engine mount structure, the left and right engine mounts are almost parallel to the horizontal axis of the engine unit. It is well known that the acoustic performance deteriorates because it cannot be disposed on the inertia spindle.

In addition, a transfer is arranged on the rear side of the engine unit, and a steering rack mounted on the front side of the dash panel in the vehicle width direction is disposed above this transfer. However, in the three-point mount system, Since the engine mount is not on the inertia spindle line of the engine unit, and the flow of the engine unit is relatively large, it is necessary to place the steal erank largely above the transfer and to avoid interference with the transfer.

For this reason, compared with two-wheel drive vehicles, the four-wheel drive has a high level of excretion of the steering rank. Therefore, two-wheel drive cars and four-wheel drive cars cannot share the front body members such as front side members and subframes. There is a need for a body front substructure exclusively for four-wheel drive vehicles, which is disadvantageously costly.

At the same time as fastening to the upper surface of M), the self-supporting bracket 9 is fastened to the subframe 2, and the steering rack 11 disposed in the vehicle width direction on the front of the collision panel other than the drawing is transferred to these transfers. It is arrange | positioned between (T) and the rear engine mount 7.

Thus, by disposing the rear engine mount 7 at a position almost immediately above the transfer T, the up and down flow of the transfer T can be suppressed as small as possible. In this example, the upper surface portion of the transfer T Although the dynamic dumper D is arranged in the above, it is possible to arrange the elevation of the steering rack 11 in accordance with the elevation of the steering rack in the two-wheel drive to the position of the dynamic dumper D.

On the rear side of U), since the transfer T exists in the substantially center portion of the vehicle width direction, the engine room E

The center member 3 disposed in the front-rear direction at the lower center of R) has the transmission T in the middle so that the rear end 3A does not interfere with the transfer T.

It is bent to the M) side, and is offset to the left side of the transfer T, is extended to the rear in a state of being in contact with the left side of the transfer T, and is coupled to the subframe 2, and the transfer of the transfer T On the right side, the exhaust tube 14 is disposed in the front-rear direction along the lower side of the adjacent shutter floor.

M)의 후측에는 플로어하측을 따라 전후방향으로 배설되는 시프트 콘트롤기구(12)가 연결되고, 상기 시프트 콘트롤기구(12)가 트랜스퍼(T)의 측부에 인접하도록 되지만, 앞에서 설명한 바와 같이 트랜스미션(T

M)의 후방에는 트랜스퍼(T)에 인접하여 센터멤버(3)의 후단부(3A)가 연재하고 있어서, 시프트 콘트롤기구(12)의 배설스페이스가 좁고, 이 시프트 콘트롤기구로서 콘트롤케이블(15)을 트랜스퍼(T)와 센터멤버(3)의 후단부(3A)사이에 배색할 여유공간밖에 확보할 수 없기 때문에, 비용적으로 저렴하고 또한 조작감이 좋은 콘트롤로드를 이용할 수 있다.This is why the transmission (T

On the rear side of M), a shift control mechanism 12 disposed in the front-rear direction along the floor lower side is connected, and the shift control mechanism 12 is adjacent to the side of the transfer T. As described above, the transmission T

The rear end portion 3A of the center member 3 extends adjacent to the transfer T behind M), and the excretion space of the shift control mechanism 12 is narrow, and the control cable 15 is used as this shift control mechanism. Since only a free space to be arranged between the transfer T and the rear end portion 3A of the center member 3 can be secured, a control rod which is inexpensive and has a comfortable operation can be used.

Thus, the present invention provides an engine mount disposing structure of a cross-mart type system capable of adjacently arranging a control rod as a shift control mechanism on the side of a transfer of an engine unit.
