Description

[Detailed description of the invention] (Field of industrial application) The present invention is mainly for use in V-type vehicles, in which a crank pulley is attached to the outside of one end in the direction of the crankshaft of the engine body, and a transmission case is assembled to the outside of the other end. Regarding the engine.

(Prior Art) Conventionally, in this type of V-type engine, it is known that an intake manifold is arranged in a V-bank space between a pair of banks. It is generally provided so as to fit within the V bank space. Furthermore, when assembling auxiliary equipment such as a power steering oil pump or a charging generator to the engine, these auxiliary equipment are installed at the end of the engine body on the side where the crank pulley is located and located at the bottom of the outer wall of each bank. That's what I do.

(Problem to be solved by the invention) In the above conventional technology, the auxiliary equipment is installed at the lower part of the outer wall of each bank at the end of the engine body on the side where the crank pulley is arranged. Even though the bank exists in an overhanging manner, the auxiliary equipment is located relatively below the engine, and when it is mounted on a vehicle, it is difficult to perform maintenance such as adjusting the tension of the belt of the auxiliary equipment. Also, the auxiliary equipment is likely to be covered with dust from the road surface.

An object of the present invention is to provide an arrangement structure for auxiliary equipment that solves these problems.

(Means for Solving the Problem) In order to achieve the above object, the present invention is a V-type engine in which a crank pulley is assembled on the outside of one end in the crankshaft direction of the engine body, and a transmission case is assembled on the outside of the other end. in which the intake manifold is arranged in a V-bank space between a pair of banks of the engine body, such that the throttle body to which the intake manifold is assembled projects into the space above the transmission case. The intake manifold is provided closer to the transmission case side of the V-bank space to form a space in which the intake manifold does not exist on the crank pulley side of the V-bank space, and is connected to the crank pulley via a belt in the space. It is characterized by the arrangement of an auxiliary machine having a pulley.

(Example) The invention will now be described with reference to illustrated embodiments.

In the drawings, reference numeral 1 indicates an engine main body having a pair of front and rear banks 2, 2, and a crank pulley 3 is located outside one end of the main body 1 in the crankshaft direction, for example, on the right side in FIG.
and the transmission case 4 is assembled on the left side in the same figure on the outside of the other end, and the intake manifold 5 is arranged in the V-bank space between the two banks 2 of the main body 1, so that the whole body is placed horizontally on the vehicle. It is equipped with a V-type engine.

In the drawing, 6 is the crank pulley 3 of the engine body 1
The timing belt cover assembled to the end wall on the installation side is shown.

Here, according to the present invention, the throttle body 7 to which the intake manifold 5 is assembled is provided close to the transmission case 4 side of the V bank space so as to protrude into the space above the transmission case 4, and the
A space 8 in which the intake manifold 5 does not exist is formed on the crank pulley 3 side of the bank space, and an auxiliary machine 9 driven via the crank pulley 3 is arranged in the space 8.

To explain this in detail, in the illustrated example, one common mounting boss 2a, which is approximately U-shaped in side view, is mounted on four mounting bosses 2a formed on the side walls of both banks 2, 2 of the engine body 1 on the V-bank space side. A bracket 10 is fixedly provided, and an auxiliary machine 9, for example, an oil pump ₉₁ for power steering, is installed at each end of the bracket 10.
and the charging generator ₉₂ are fixed with bolts 11 at one end of each of their outer circumferences, and the other ends of their respective outer circumferences are fixed with bolts 12 in each elongated hole 10a formed in the middle part of the bracket 10, and the pump The crank pulley 3 and the pulley 13 of the pump 9 ₁ are arranged such that the crank pulley 3 and the generator 9 ₂ can swing along the long holes 10 a using the bolts ₁₁ as fulcrums.
The tension of the V-belts 15, 15 stretched between the generator ₉₂ and the pulley 14 of the generator 92 can be adjusted.

In the drawing, reference numeral 16 indicates a cover attached to the end of the bracket 10 so as to cover both pulleys 15, 15 from above.

(Function) By arranging the auxiliary machine 9 in the space 8 formed on the crank pulley 3 side of the V bank space where the intake manifold 5 does not exist, the auxiliary machine 9 is located relatively above the engine main body 1 and is located in both banks 2. , 2, and is therefore easily accessible to the operator when performing operations such as belt tension adjustment, thereby improving work efficiency.

Further, since the auxiliary machine 9 is located relatively above the engine, and the engine body 1 is located below the auxiliary machine 9, dust from the road surface is less likely to fall on the auxiliary machine 9.

(Effects of the invention) As described above, according to the invention, the throttle body to which the intake manifold is assembled is provided close to the transmission case side of the V-bank space so as to protrude into the upper space of the transmission case. A space where the intake manifold does not exist is formed on the crank pulley side of the V-bank space, and an auxiliary machine having a pulley connected to the crank pulley via a belt is placed in this space, and is orthogonal to the engine crankshaft. The increase in width in the direction can be suppressed, and the auxiliary equipment can be
It can be placed efficiently in the bank space, making the entire engine more compact.The engine body also acts as a shield against dust from the road surface, making it difficult for auxiliary machinery to get dusty. It can be placed exposed upward in the bank space, and maintenance work such as belt tension adjustment can be performed from above without being obstructed by each bank or intake manifold, which has the effect of improving maintainability.
