Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a golf cart for transporting a caddy bag.

[Conventional technology]

Golf carts used on golf courses of this type are required to operate quietly in consideration of the impact on players. For this reason, when using an engine as the driving source for a golf cart, the forced air-cooled engine body, intake system, and exhaust system are all housed within the vehicle body cover to prevent engine noise from leaking to the outside as much as possible. ing.

[Problem that the invention seeks to solve]

However, in a golf cart, the space is extremely limited, and due to the need for sound insulation, the engine or muffler that dissipates heat is housed inside the cover, and the intake system or electrical equipment that needs to be kept as low as possible is housed inside the cover. Many parts, such as items, must be stored together. That is,
Exhaust heat tends to get trapped inside the vehicle body cover, and as this is circulated, the air temperature around the engine tends to rise, which is a problem.

[Means for solving problems]

The present invention was made in view of these circumstances, and it is an object of the present invention to provide a golf cart that can prevent the temperature of the air around the engine from increasing. In the golf cart according to the present invention, a cooling air exhaust passage of a forced air-cooled engine housed in an engine room is connected to a muffler room that is partitioned by a partition wall on the side of the engine room and opened downward.

[Effect]

In the present invention, exhaust heat is not dissipated from the muffler into the engine compartment, and fresh air that flows into the engine compartment cools the engine, flows into the muffler compartment, cools the muffler, and then exits the vehicle body. This prevents exhaust heat from being transmitted to the engine compartment.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan sectional view showing a golf cart according to the present invention, FIG. 2 is a side sectional view, FIG. 3 is a perspective view, and FIG. 4 is a sectional view taken along the line IV-IV in FIG. In the figure,
The reference numeral 1 indicates a golf cart. This golf cart 1 is a four-wheel standing type golf cart on which the driver stands at the rear of the vehicle.
The vehicle consists of a driving engine 3 mounted approximately in the center of the vehicle, a resin vehicle body cover 4 that covers approximately the entire upper part of the engine 3 and the vehicle body frame 2, front wheels 5, 5, rear wheels 6, and the like. There is.

The vehicle body frame 2 has a ladder shape extending in the longitudinal direction of the vehicle body, a front frame 2a extending between the front wheels 5 is narrow, and a rear frame 2b extending rearward from the front wheels 5 is wide. A bumper 10 is provided at the front end of the front frame 2a.
A lower support member 11 for supporting the lower part of the caddy bag is disposed behind the lower support member 11 in the vehicle width direction. On the other hand, at the rear of the rear frame 2b, there is a driver's footboard 1 on which a caddy, player, etc. stands as a driver.
2 is provided, and a stay 14 that supports the steering shaft tube 13 from the rear is connected to the front thereof. 15 is stay 1
4, and is an upper support member that supports the upper part of the caddy bag.

The vehicle body cover 4 has a substantially box shape that is opened downward, and covers the upper part of the front wheels 5 and the rear wheels 6 as well.
It is formed of an upper cover 4b that closes an opening 16 provided on the upper surface of the cover main body 4a, and a lower cover 40 that covers between the cover main body 4a and the rear frame 2b.

Reference numeral 20 denotes an engine chamber formed within the vehicle body cover 4 and for accommodating the engine 3. This engine compartment 20 includes a vehicle body cover 4, left and right front fenders 21a that cover the front wheels 5,
21b, left and right rear fenders 22a, 22b that cover the rear wheel 6
, is surrounded by a bottom plate 23 provided on the lower side of the rear frame 2b, and is open to the front between the front fenders 21a and 21b.

A muffler chamber 25 is formed on the right side of the engine chamber 20 in the vehicle body cover 4 to accommodate the muffler 26. The muffler chamber 25 is partitioned from the engine chamber 20 by a partition wall 30 and is open downward. In other words, by providing this partition wall 30, the space inside the vehicle body cover 4 is divided into the engine compartment 20 and the muffler compartment 25.
It is defined as

The engine 3 is a forced air-cooled engine, and includes a shruff that covers the engine body and forms a passage through which cooling air flows in the vehicle width direction, a blower fan disposed on the right side of the shruff,
and a cylindrical passage forming member 36 connected to the left side of the shroud and forming a discharge passage 35. The passage forming member 36 extends to the right after being bent into an arc shape, passes through the partition wall 30 at the top and faces the muffler chamber 25, thereby connecting the engine cooling air discharge passage 35 to the muffler chamber 25. There is. 37 is the insertion hole 3 of the partition wall 30
This is a bellows that seals between Oa and the passage forming member 36.

40 is an air cleaner disposed between the front fenders 21a and 21b, and 41 is an intake pipe connecting the air cleaner 40 and the engine 3, which is disposed on the left side of the engine 3. An exhaust pipe 42 connects the engine 3 and the muffler 26, and is piped to pass through the passage forming member 36.

43 is a fuel tank disposed on the outside of the intake pipe 41;
Together with the battery 44, it forms a kind of sound insulating wall that covers the sides of the engine 3, reducing the emission of engine noise. Further, since the fuel tank 43 is located near the intake pipe 41 where the temperature is relatively low, it is less affected by heat.

Note that 45 is a sound-absorbing material attached to the partition wall 30 and the inner surface of the vehicle body cover 4 to absorb engine noise.

In the golf cart configured in this manner, the engine compartment 20 and the muffler compartment 25 are separated by the partition wall 30, so exhaust heat is not dissipated into the engine compartment 20 from the muffler 26. Also, engine 3 is started,
When the blower fan is driven, the pressure near the air intake port of the fan becomes negative, so that fresh air flows into the engine compartment 20 from between the front fenders 21a and 21b. This fresh air is directed into the shroud by a blower fan, passing through the sides of the cylinders and cylinder heads to cool the engine. The cooling air after cooling the engine passes through the passage forming member 36, flows into the muffler chamber 25, cools the muffler 26, and then is discharged from below to the outside of the vehicle body. In the embodiment, since the exhaust passage 35 is connected to the upper part of the muffler chamber 25 where hot air tends to accumulate, the muffler chamber 25 is effectively cooled. Therefore, the exhaust heat dissipated into the muffler chamber 25 from the muffler 26 can be suppressed from being transmitted to the engine chamber 20.

Therefore, the exhaust heat dissipated from the muffler 26 is less likely to be trapped in the engine room 20, and the amount of exhaust heat circulating around the engine 3 is reduced.

〔Effect of the invention〕

As described above, according to the present invention, the muffler is accommodated in the muffler chamber that is partitioned by a partition wall on the side of the engine room and opened downward, so that exhaust heat is not dissipated from the muffler into the engine room.

In addition, the cooling air exhaust passage for the forced air-cooled engine housed in the engine compartment is connected to the muffler compartment, so the fresh air that flows into the engine compartment cools the engine and flows into the muffler compartment to cool the muffler. After that, the exhaust heat is discharged outside the vehicle body, which prevents the exhaust heat dissipated from the muffler from being transmitted to the engine compartment.

Therefore, the exhaust heat dissipated from the muffler is less likely to be trapped in the engine compartment, and the amount of circulating exhaust heat is reduced, so that the temperature of the air around the engine can be prevented from rising.
