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]

Some golf carts of this type have a driving engine mounted in the center of the vehicle body, and the driver rides while standing at the rear. Incidentally, such golf carts are required to operate quietly in consideration of the impact on players and drivers. For this reason, the 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.

[Problem that the invention seeks to solve]

However, in such a structure, the space is extremely limited, and due to sound insulation requirements, the engine or muffler, which dissipates heat, is placed inside the cover, which has few open parts, and the air cleaner and intake air, which are desired to be kept as low as possible, are placed inside the cover. Many components, such as the intake system made of pipes and electrical equipment, must be housed together. That is, exhaust heat tends to be trapped within the vehicle body cover and is circulated, resulting in a problem that the temperature of the intake air taken in from the air cleaner becomes high. To solve this problem, it may be possible to create an opening on the side of the vehicle body cover and direct the air intake of the air cleaner toward this opening to suck in outside air. becomes larger.

[Means for solving problems]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a golf cart that can lower the intake air temperature and reduce the intake noise that can be heard by the driver. The golf cart according to the present invention includes an engine mounted in the center of the vehicle body, a muffler disposed on the side thereof, and a vehicle body cover that covers the entirety of the engine. An air cleaner is installed between the

[Effect]

In the present invention, the air cleaner is located at the front from the engine.
\As the air cleaner moves away, fresh air is supplied to the air cleaner through the opening.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. 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 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 in which the driver rides while standing at the rear of the vehicle body, and includes a body frame 2, a driving engine 3,
, a resin vehicle body cover 4, front wheels 5, rear wheels 6, etc.

The vehicle body frame 2 consists of a narrow front frame 2a and a wide rear frame 2b, each of which has a ladder-like structure made up of a pair of tube bodies arranged on the left and right sides of the vehicle body and a cross member connecting these. It is formed. The engine 3 is mounted in the center of the vehicle body frame 2. On the other hand, a lower support member 10 for supporting the lower part of the caddy bag is disposed in the front part in the vehicle width direction, and a driver's footboard 11 is provided in the rear part on which a caddy, player, etc. stands as a driver. It is being The upper part of the caddy bag has a stay 1 that supports the steering shaft tube 12 from the rear.
It is supported by an upper support member 14 provided at the upper end of 3.

A muffler 20 is disposed on the right side of the engine 3 and connected to the engine 3 via an exhaust pipe 21.

The vehicle body cover 4 covers the engine 3 and the muffler 2.
0. A substantially box-shaped cover body 4a that is opened downward so as to cover the entire intake system components, which will be described later, from above, and an upper cover 4h that covers the upper opening of the cover body 4a.
The cover is formed of a lower cover 40 that covers the lower part of the main body 4a.

That is, inside the vehicle body cover 4, the vehicle body cover 4, the front wheel 5
A space is formed surrounded by left and right front fenders 25a, 25b that cover the rear wheels 6, left and right rear fenders 26a, 26b that cover the rear wheels 6, and a bottom plate 27 provided on the lower side of the rear frame 2b. is defined by a partition wall 30 into an engine chamber 31 and a muffler chamber 32. Here, in order to open the vehicle body cover 4 at least forwardly, the front portion of the cover main body 4a extends forward along the upper surfaces of the front fenders 25a and 25b. For this reason, the front fender 2
An opening 33 opened to the front is formed between 5a and 25b.

35 is an air cleaner, which is located between the front fenders 25a and 25b, that is, between the opening 33 and the engine 3, as shown in FIG.
is placed between. The air cleaner 35 consists of a cylindrical resin case and an element housed inside the case, and is mounted with a downwardly inclined surface. An intake duct 35a protruding in the tangential direction is integrally provided in the upper part of the case. 36 is an intake passage forming member that connects the air cleaner 35 and the engine 3. This intake passage forming member 36 is disposed on the left side of the engine 3 to avoid the influence of exhaust heat, and its front portion is connected to the upper surface of the case of the air cleaner 35 in the axial direction.
The rear part is connected to the back of the engine 3 via a carburetor 37.

Reference numeral 40 denotes an exhaust pipe that is connected to a shroud provided in the engine 3 and discharges cooling air into the muffler room 32. ,
41 is a fuel tank, and 42 is a battery.

In the golf cart configured in this way, since the air cleaner 35 is disposed between the engine 3 and the opening 33 formed between the front fenders 25a and 25b, the air cleaner 35 can be moved forward from the engine 3. . Therefore, the air cleaner 3 which is the source of intake noise
5 away from the driver riding in the rear of the vehicle, the intake noise heard by the driver can be reduced.

Furthermore, when the engine 3 is started, the pressure near the intake duct 35a of the air cleaner 35 becomes negative, so the vehicle body cover 4
Fresh air whose temperature is relatively low compared to the air inside flows in through the opening 33 and is supplied to the intake duct 35a. Therefore, since the air cleaner 35 can suck in fresh air, the temperature of the intake air does not become high. Here, since the fresh air has less dust than the air in the engine room 31, the elements of the air cleaner 35 are less likely to be clogged. Note that the air taken into the air cleaner 35 is supplied to the engine 3 from the intake passage forming member 36 and is combusted, and is led to the muffler 20 from the exhaust pipe 21, cooled and muffled, and then discharged to the outside of the vehicle body.

Further, since the opening 33 is opened to the front, when the golf cart 1 is running, the intake pressure can be increased by the wind while the golf cart 1 is running, and the interior of the vehicle body cover 4 can be ventilated.

〔Effect of the invention〕

As explained above, according to the present invention, the engine is mounted in the center of the vehicle body, the muffler is disposed on the side of the engine, the whole is covered with the vehicle body cover, and the vehicle body cover is opened at least forwardly, and the muffler is disposed on the side thereof. Since the air cleaner is disposed between the opening and the engine, the air cleaner moves forward away from the engine and fresh air is supplied to the air cleaner from the opening.

Therefore, since the air cleaner can take in fresh air with a relatively low temperature, the intake air temperature does not become high. Furthermore, since the air cleaner, which is the source of intake noise, is moved away from the driver at the rear, the intake noise that the driver hears becomes smaller.
