Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle powertrain structure in which an engine and a mission are horizontally arranged.

[0002]

2. Description of the Related Art Generally, in a vehicle of a type in which an engine is laterally arranged in front of a vehicle body, an exhaust manifold for discharging exhaust gas to the outside of the engine is
It is connected to the front of the engine, and the air taken in from the front of the vehicle reduces the temperature of the exhaust gas,
By keeping the exhaust pipe away from the passenger compartment as much as possible, it is possible to prevent hot air from staying inside the passenger compartment. And
The exhaust pipe connected to the front of the engine is bent downward at one end and then extends under the oil pan of the engine to the rear portion of the vehicle body.

However, in a power train structure in which the engine is horizontally placed and the mission is also horizontally placed behind it, the lower surface of the mission is lower than the lower surface of the oil pan of the engine. However, there is a problem that the exhaust pipe cannot be passed from the front of the engine to the rear of the vehicle. As a method for solving this, there is a method of connecting an exhaust manifold to the rear of the engine and guiding the exhaust pipe to the rear of the engine as it is.

[0004]

However, in the exhaust manifold, in order to avoid exhaust interference of each cylinder, in the vicinity of the portion connected to the cylinder head,
It must be separated for each cylinder. In general, the exhaust manifold is extended to a certain length from the cylinder head in a separated state for each cylinder, and then is integrated into one exhaust pipe.

Here, in an FR vehicle or a four-wheel drive vehicle, a propeller shaft for transmitting power to the rear wheels via a transmission is connected to the rear of the engine in a substantially central portion in the vehicle width direction. The exhaust pipe was united above the propeller shaft. And
It was supposed to be guided to the rear of the vehicle through the side of the propeller shaft. Therefore, when the exhaust manifold is independent for each cylinder and it is attempted to extend by a length sufficient to prevent exhaust interference, for example, when it is extended downward, the gathering point of the exhaust manifold shifts downward. Therefore, the propeller shaft is driven downward so as not to interfere with this, and there is a problem that the minimum ground clearance of the vehicle cannot be secured. In addition, when the exhaust manifold is separated and extended to the rear of the vehicle body, multiple exhaust manifolds bite into the vehicle compartment in the widthwise direction of the vehicle, which reduces the foot space in the vehicle compartment and improves comfort. There was a problem of damage.

[0006] Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide an exhaust manifold in a state in which it is separated by a length sufficient to prevent exhaust interference of each cylinder. An object of the present invention is to provide a powertrain structure for a vehicle that can be extended, can secure a minimum ground clearance, and does not impair comfortability.

[0007]

In order to solve the above-mentioned problems and to achieve the object, a powertrain structure for a vehicle according to the present invention is an engine arranged laterally with respect to a vehicle body and an engine adjacent to the engine. The transmission, which is arranged substantially parallel to the engine, the propeller shaft for transmitting the rotational force of the engine to the wheels on the side remote from the mission, and the mission of the engine. A plurality of exhaust pipes connected to the side to which is connected and extending in substantially the same direction as the extending direction of the propeller shaft, the plurality of exhaust pipes being gathered below the propeller shaft. It is characterized by

In the powertrain structure for a vehicle according to the present invention, the engine and the mission are arranged in front of the vehicle body.
Further, in the powertrain structure for a vehicle according to the present invention, a transfer case extending in substantially the same direction as the extending direction of the propeller shaft is connected to the transmission, and the plurality of exhaust pipes are connected to the transfer case. The feature is that it is fixed.

[0009]

As described above, since the vehicle powertrain structure according to the present invention is constructed, the exhaust manifold is assembled under the propeller shaft so that the propeller shaft is provided in the space above the assembled exhaust pipe. Since the exhaust manifold can be extended downwards independently by a length sufficient to prevent exhaust interference, the propeller shaft is not driven downwards and the minimum ground clearance is sufficient. You can earn Moreover, since the exhaust manifold is not extended to the rear of the vehicle body, the exhaust manifold does not bite into the vehicle interior, and it is possible to prevent the living space in the vehicle interior from being damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a plan view showing a front structure of an automobile to which a power train structure of one embodiment is applied. In FIG. 1, a vehicle body 10 (see FIG. 2) extends in the vertical direction, the upper side in the figure is the rear side of the vehicle body, and the lower side is the front side of the vehicle body. Frame 12 that constitutes the vehicle body 10
On the other hand, the engine 14 is arranged in a state in which its crankshaft is arranged along the width direction of the vehicle body 10, that is, in a horizontal position. Here, the engine 14 is a serial type 6
It is a cylinder engine and is mounted on the vehicle body 10 with the cylinder head tilted at 30 ° rearward of the vehicle body.

This engine 14 at the rear of the engine 14
The mission 16 is horizontally disposed at a position adjacent to (see FIG. 2). The vehicle shown in FIG. 1 is a four-wheel drive vehicle, and the rotational force of the crankshaft of the engine 14 is arranged in the transfer case 20 connected to the mission 16 and the mission case 18 housing the mission 16. It is divided into front wheels 24 and rear wheels (not shown) and transmitted via the center differential 22 (see FIGS. 2 and 7). A propeller shaft 26 for transmitting the power split by the center differential 22 to the rear wheels is connected to the rear portion of the transfer case 20 and also the transfer case 2
A bearing 28 for rotatably supporting the propeller shaft 26 is provided in a substantially cylindrical case 28 connected to 0.
Is built in. Also, Center Differential 2
The power split for the front wheels by 2 is applied to the front wheel axle 34 and the wheels 24 for the left and right wheels by the front wheel differential 32.
Be transmitted to. Details of the configuration of the transfer 36 including the center differential 22 and the front wheel differential 32 will be described later.

Here, in the automobile to which the embodiment is applied, as described above, since the mission 16 is connected to the rear of the engine 14 in a horizontal state, the lower portion of the mission interferes with the exhaust pipe. It is difficult to guide the vehicle to the rear of the vehicle body through the lower side of the engine 14 (see FIG. 2).
Therefore, the exhaust manifolds 38a to 38f are connected to the rear of the engine 14, and the intake manifolds 40a to 40f are connected to the front of the engine 14.

The structure of the exhaust system and the intake system will be specifically described. Intake manifolds 38a to 38f are connected to the front portion of the engine 14 at positions corresponding to the cylinders, and air is introduced into the combustion chamber of each cylinder. And fuel. Further, exhaust manifolds 38a to 38f for guiding the exhaust gas discharged from the combustion chamber to the outside are connected to a portion of the cylinder head 14a at the rear of the engine 14 corresponding to each cylinder. Exhaust manifold 38a connected to each of these cylinders
38 f are independent of each other immediately after the connection to the cylinder head 14a in order to prevent exhaust interference of each cylinder. Then, for each of the three cylinders (first to third cylinders and fourth to sixth cylinders) in which exhaust interference is less likely to occur.
One for each cylinder), that is, a total of two. However, it is assumed that the cylinders of the engine 14 are arranged in the engine body in the order of the first cylinder and the second cylinder from the right side in the drawing. These exhaust manifolds 3
2 exhaust pipes 42a after 8a to 38f are put together,
42b respectively pass through both sides of the propeller shaft 26 and extend to the lower side of the propeller shaft 26. Under the propeller shaft 26, 42b are gathered as one exhaust pipe 44 and further extended toward the rear of the vehicle body. There is.

Next, FIG. 2 is a side view of FIG. 1 viewed from the right side. The left side of the drawing shows the front of the vehicle body, and the right side shows the rear of the vehicle body. The engine 14 is arranged in an engine room 46 arranged on the left side of the vehicle body 10 in the figure with the cylinder head 14a thereof being tilted backward by 30 °. A pulley 48 is attached to one end of a crankshaft on the front side of the paper surface of the engine 14, and a belt 52 is stretched between the pulley 48 and a pulley 50a provided in an auxiliary machine 50. And this auxiliary machine 50
Are driven as the crankshaft rotates.

Further, as will be described in detail later, the rotational force of the crankshaft is transmitted to the center differential 22 through the gear train 54 constituting the mission 16 in sequence,
The center differential 22 divides the power for the front wheels and the power for the rear wheels. The power for the rear wheels is transmitted to the rotary shaft 56 that is rotatably supported by the bearing 30 in the case 28 that projects rearward from the transfer case 20. A propeller shaft 26 extending further rearward of the vehicle body is connected to the rotary shaft 56, and the propeller shaft 26 drives rear wheels. A gear box 58 for steering is arranged behind the transfer case 20.
The rotating shaft 60 connected to the steering wheel 8 is connected to the handle 62.

Further, as described above, six intake manifolds 40a to 40f are connected to the front of the cylinder head 14a of the engine 14 for each cylinder.
Six exhaust manifolds 38a to 38f are connected to the rear of the cylinder head 14a so as to correspond to the respective cylinders. These exhaust manifolds 38a-
In order to avoid the exhaust interference of each cylinder, 38f independently extends to the position of A part in the figure, and in the A part, three exhaust manifolds 38a to 38c corresponding to the first cylinder to the third cylinder are provided. , And the three exhaust manifolds 38d to 38f corresponding to the fourth to sixth cylinders are grouped into one, respectively. Then, each of these three exhaust manifolds 38a to 38c, 38
Immediately after the d to 38f are grouped into one, these two exhaust pipes 42a and 42b are connected to the case 28.
It is fixed to the case 28 by exhaust pipe brackets 62 (see FIGS. 3 and 4) on both sides of. The exhaust pipes 42a and 42b extend further rearward from this fixed position and are gathered under the propeller shaft 26 into one exhaust pipe 44, which is connected to an exhaust pipe 64 extending to the rear portion of the vehicle body. ing.

In this way, the exhaust pipe is divided into two parts and extended to the lower side of the propeller shaft 26, and the lower pipe of the propeller shaft 26 joins together, so that the following effects are produced. Exhaust manifold 38a-38f
In the vicinity of the part connected to each cylinder, in order to avoid exhaust interference of each cylinder, in an independent state as much as possible,
It needs to be kept for some time. Therefore, when the exhaust manifolds 38a to 38f are arranged so as to join on the upper side of the propeller shaft 26 as in the conventional case, it is attempted to independently extend the exhaust manifolds 38a to 38f by a length sufficient to prevent exhaust interference. Then, the collecting portion C of the exhaust manifolds 38a to 38f moves in the direction indicated by the arrow D, or the propeller shaft 26 moves in the direction indicated by the arrow E.

When the collecting portion C is moved in the direction indicated by the arrow D, the exhaust pipes 42a and 42b are still separated into two pieces, and the exhaust pipes 42a and 42b are spread in the vehicle width direction and bite into the vehicle compartment. As a result, the space around the driver's feet becomes smaller, which hinders driving. On the other hand, when the propeller shaft 26 is moved in the direction of the arrow E, the transfer 36 and the propeller shaft 26 are arranged at a lower position of the vehicle body 10, so that the above-mentioned steering gear box 58 from the ground is moved. The height of the ground becomes low, and the minimum ground clearance cannot be earned. In addition, the propeller shaft 26
In the vehicle body front-rear direction, it is desirable that the portion not protected by the wheels is located as high as possible from the ground, so that the rear portion of the vehicle body of the propeller shaft 26 is arranged in a state of being lifted via a universal joint or the like. Such consideration is necessary.

On the other hand, as in one embodiment, the exhaust pipe 4
If the 2a and 42b are assembled under the propeller shaft 26, the space at the foot of the passenger compartment will not be narrowed and the propeller shaft 26 can be arranged at a high position, so that the minimum ground clearance can be reduced. You can earn enough. Further, since it is not necessary to bend the propeller shaft 26 on the way, power transmission loss is reduced.

Next, FIG. 3 shows the exhaust manifold 3.
8 (exhaust manifolds 38a to 38c and 3
It is the elements on larger scale which showed the attachment state to the case 28 of what collected 8d-38f respectively. A substantially cylindrical case 28 is fixed to the transfer case 20 as described above. Mounting portions 28a and 28b for mounting the exhaust pipe bracket 62 are integrally formed on the case 28. The exhaust manifold 3 is attached to the mounting portions 28a and 28b via an exhaust pipe bracket 62.
8 and the exhaust pipes 42a and 42b are fixed.

The exhaust manifold 38 and the exhaust pipes 42a and 42b are respectively divided above and below the exhaust pipe bracket 62, and each of the three exhaust manifolds 38a to 38a extending from the cylinder head 14a.
The end portion of the exhaust manifold 38 is fixed to the upper surface of the exhaust pipe bracket 62 by a bolt at a position immediately after the 38c and 38d to 38f are combined.
The exhaust pipe 42a, which is formed of a pipe having flexibility in the bending direction, is provided at the front end of the exhaust pipe extending rearward of the vehicle body.
42b is connected. Then, the exhaust pipe 42a,
Flange portions are formed at both ends of 42b, and the flange portions at one ends of the exhaust pipes 42a and 42b are fixed to the lower surface of the exhaust pipe bracket 62 with bolts. Further, the flange portion at the other end is fixed to the exhaust pipe 64 extending rearward.

As described above, if the exhaust manifold 38 and the exhaust pipes 42a and 42b are fixed to the case 28 by the exhaust pipe bracket 62, the following effects are produced. By fixing the exhaust pipe 42 to the case 28, even if vibration of the engine 14 in the direction of the arrow (so-called pitching vibration) occurs in FIG. 3, the root positions of the exhaust manifolds 38a to 38f (F
Part) and the position of the exhaust pipe bracket 62 (G part), the force of this vibration can be received, so cracks or the like occur at the root positions (F part) of the exhaust manifolds 38a to 38f where stress concentration easily occurs. It can be prevented from occurring. Further, for example, in the G portion, the exhaust manifold 38
If the a to 38f and the exhaust pipes 42a and 42b are not supported, the pitching vibration of the engine 14 causes the exhaust manifolds 38a to 38f and the exhaust pipes 42a and 42f.
Although it works in the direction of pulling and compressing b, a pipe-shaped member generally has poor flexibility for pulling and compressing. On the other hand, the exhaust manifold 38a-
If the 38f and the exhaust pipes 42a and 42b are supported, the exhaust pipes 42a and 42b have a force to bend the exhaust pipe portion behind the G portion. Therefore, if a flexible pipe or the like is used, the engine 14 It is possible to easily absorb a small bending displacement due to the vibration. That is, supporting the exhaust manifolds 38a to 38f and the exhaust pipes 42a and 42b in the G portion has the effect of improving the durability of the roots 38a to 38f of the exhaust manifold, and at the same time, the alive 38a to 38f and the exhaust pipe 42a. , 42b is changed from a tensile compressive force to a bending force, so that there is an action of making the displacement of the pipe more flexible.

Further, as shown in FIG. 4, the exhaust manifolds 38a to 38f and the exhaust pipe 42 are provided by a bracket 63 provided so as to extend from the cylinder head 14a.
In the case of supporting a and 42b, when the bracket 63 becomes a cantilever and its length becomes long,
As a matter of course, the rigidity of the bracket 63 is lowered, and the exhaust manifolds 38a to 38f and the exhaust pipe 42 are reduced.
The supporting rigidity of a and 42b decreases. On the other hand, if configured as described above, the exhaust manifolds 38a to 38f and the exhaust pipes 42a and 42b can be supported in the immediate vicinity of the outer peripheral portion of the case 28, and therefore the exhaust manifolds 38a to 38f and the exhaust pipes 42a and 4a.
The supporting rigidity of 2b is improved. If the support rigidity of the exhaust manifolds 38a to 38f and the exhaust pipes 42a and 42b is improved, the displacement of the engine 14 due to the vibration of the engine 14 must be absorbed by the portion of the exhaust pipe other than the supported portion. , According to the above structure,
Since the displacement is in the direction of bending the exhaust pipe, there is no problem because it is highly flexible with respect to deformation.

FIG. 5 is a perspective view showing how the exhaust pipe bracket 62 and the exhaust manifold 38 are attached to the case 28. As shown, the exhaust pipe bracket 62 is attached to the mounting portions 28a and 28b formed on both sides of the case 28.
Is fixed, and the flange of the exhaust manifold 38 is fixed to the exhaust pipe bracket 62. As described above, according to the above-described structure, the exhaust manifolds 38a to 38f are separated from each cylinder, and the exhaust manifolds 38a to 38f are assembled under the propeller shaft 26 so that the exhaust manifolds 38a to 38f can be installed in the vehicle interior space.
