Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a transversely mounted V-engine vehicle in which a V-engine is mounted transversely in the engine room at the front of the vehicle, and in particular, to It's about layout.

[Conventional technology]

Conventionally, as shown in Japanese Utility Model Publication No. 63-23219, the engine was mounted horizontally in the engine room at the front of the vehicle, and the transmission, differential gear, steering mechanism, etc. were arranged. Transverse engine cars are known. The transverse engine vehicle shown in this publication has the center of the front wheel differential positioned forward of the center of the engine in order to secure legroom in the passenger compartment and improve weight distribution around the front wheel axle. 11111 is placed in front of the engine.

There is also a vehicle equipped with a V-type engine, which is placed horizontally and installed in the engine room along with a steering mechanism and the like.

[Problem to be solved by the invention]

By the way, in the layout of the steering mechanism consisting of a rack shaft, a pinion, etc., shown in the above publication, the steering mechanism is placed in front of the horizontally placed engine in the engine room, and in addition to this, the steering mechanism It is also known that the steering mechanism is located at the rear of the engine room (at the rear of the engine room). Even when the V-type engine was mounted horizontally, the steering mechanism was placed in front or behind it. However, according to such a layout, it is necessary to secure a space for arranging the steering mechanism in the engine room in front of or behind the engine, and there is room for improvement in this layout.

In view of these circumstances, the present invention has been developed to provide a steering mechanism that utilizes dead space without taking up space in front of or behind the engine, especially in a structure in which a type 2 engine is placed horizontally in the engine compartment at the front of the vehicle. It is an object of the present invention to provide a horizontal type V-type engine 2 that can be effectively incorporated.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a horizontal type V-type engine 2 in which a type engine is mounted horizontally in the engine room at the front of a vehicle, and the steering mechanism is connected to both sides of the V-type engine. It is placed between banks.

(Function) According to the above configuration, the dead space that exists between both banks, which is unique to a V-type engine, is utilized for arranging the steering mechanism.

(Example) Embodiments of the present invention will be described based on the drawings.

1 and 2 show an embodiment of the present invention. In the plan view of FIG. 1, the lower side of the figure is the front side of the vehicle, and in the side view of FIG. 3, the left side of the figure is the front side of the vehicle. , and FIG. 2 is a view of the engine, drive system, steering system, etc. inside the engine compartment as seen from the front side of the vehicle.

In these figures, 1 is an engine room, which is formed at the front of the vehicle. Further, reference numeral 2 denotes a ■-type engine mounted in the engine room 1, which is arranged horizontally with respect to the vehicle, that is, arranged so that the engine output shaft extends in the vehicle width direction. This ■ type engine 2
has a pair of front and rear banks 3.4 consisting of a cylinder block with a V-shaped upper part and two cylinder heads connected to the upper end of the cylinder block. 3 is installed so that it is tilted forward to the extent that it is approximately horizontal. Both banks 3 and 4 of this engine 3
An intake passage 5 is installed in a part of the space between them. Further, on each outer surface of the front bank 3 and the rear bank 4 of the engine 2 (the lower surface of the front bank 3 and the rear surface of the rear puncture 4), a front exhaust pipe 6 and a rear exhaust pipe 6 are provided. An exhaust pipe 7 is connected. The front exhaust pipe 6 passes below the engine 2, and the rear exhaust pipe 7 passes behind the engine 2, and both exhaust pipes 6, 7 are connected at the lower rear of the engine 2.
are gathered together, and a common exhaust pipe 8 downstream of the gathering portion extends toward the rear of the vehicle.

A transmission 9 equipped with a well-known transmission mechanism is connected to the engine 2 in a transmission case 9a, and in the example shown in the figure, the transmission 9 is located on the side of the engine 2. Transmissions 9 are connected in series.

A drive system such as a differential ALL device that transmits the power output from the transmission 119 to the wheels is also installed in the engine room 1, and when applied to a four-wheel drive vehicle, the front differential 11,
A center differential 12, a direction conversion gear 13 for transmitting power toward the propeller shaft, and the like are provided. The front differential 11, center differential 12 and direction conversion gear 13 are as follows:
For example, as shown in the figure, it is disposed in front of the lower part of the transmission 19 and below the engine 2, and is housed in a housing portion 14 that is connected to the transmission case 9a. Left and right front wheel axles 15 are connected to the front differential 11, and each front wheel axle 1
Left and right front wheels 16 are connected to 5. The direction conversion gear 13 also includes a propeller shaft 17 extending toward the rear of the vehicle.
is connected.

A steering mechanism 20 includes a rack shaft 22 slidably held in a holder 21 extending in the vehicle width direction, a pinion 23 that meshes with the rack, a back cylinder (not shown), and the like. The steering mechanism 20 is disposed in a space between both banks 3.4 of the V-type engine 2, and both ends of the holder 21 are attached to the side frame 30 via brackets 30a.

The pinion 23 is connected to a steering wheel (not shown) via a shaft 24 passing above the transmission 8, a joint 25, and the like. Furthermore, a pair of tie rods 27 are coupled to a member 26 coupled to the rack shaft 22. On the other hand, on both left and right sides of the engine room 1, a knuckle 28 extends upward from the end position of the lower arm 31 of the suspension to a height position approximately corresponding to the steering mechanism, and a knuckle arm 29 protruding forward from the upper part of the knuckle arm 28 extends upward from the end position of the lower arm 31 of the suspension, and a knuckle arm 29 protrudes forward from the upper part of the knuckle arm 28. is connected to. Note that 32 is a damper of the suspension.

According to the horizontally mounted V-type engine vehicle of this embodiment as described above, the dead space existing between both banks 3.4 of the V-type engine 2 is effectively utilized, and the steering mechanism 20 is disposed in this area. Therefore, there is no need to secure space for the steering mechanism 20 in front or behind the engine 2. Note that although the intake passage 5 is also arranged between the left and right banks 3.4, a sufficient space is left for arranging the steering mechanism 20.

Furthermore, if the V-type engine 2 is tilted forward to the extent that the front side bank 3 is approximately horizontal as in this embodiment, and the steering mechanism 20 is disposed between them, the V
Since the position of the space between the banks 3.4 is lower than when the engine is not tilted, the layout of the shaft 24, etc. relative to the steering mechanism 20 is facilitated, and since the space faces forward, the position of the space between the banks 3.4 is lowered.
Assembling is easier and workability during service is also improved.

〔Effect of the invention〕

As described above, the present invention arranges the steering mechanism between both banks of the V-type engine that is mounted horizontally in the engine room, thereby securing space for arranging the steering mechanism in front and behind the engine. This allows the steering mechanism to be effectively laid out by utilizing the dead space between the two banks.
