Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a four-wheeled all-terrain vehicle (hereinafter referred to as A) equipped with a front guard for protecting a vehicle and a winch for pulling luggage or the like at a front portion of the vehicle.
More specifically, the present invention relates to a winch mounting structure provided in the vehicle.

[0002]

2. Description of the Related Art Since this type of winch often travels on uneven terrain, the above-mentioned riding type four-wheeled off-road vehicle is towed by trees and fixed objects ahead when it gets stuck in a swamp. By tying one end of the rope, winding up the rope with a winch and pulling it, you escape from the marsh,
It is used for applications such as pulling using a winch when moving heavy objects.

Conventionally, in the case of the above-described winch 71, as shown in FIG. 8, a winch mounting portion 72 is generally provided at a front portion of a vehicle 70 in front of a front guard 73. It is. In some cases, as shown in FIG. 8, a guard 74 dedicated to the winch 71 is provided to protect the winch.

[0004]

However, there is room for improvement in the following points in the riding type four-wheel uneven terrain vehicle provided with the winch according to the above-mentioned conventional mounting structure. That is, a part of the winch protrudes forward of the vehicle, which hinders driving. Also, obstacles hit the winch directly,
It may be damaged.

[0005] The winch mounting portion requires strength and has a large number of parts, so that it is heavy and expensive.

[0006] Since the winch projects forward of the vehicle, the appearance is poor.

[0007] For the above reasons, the specifications of the vehicle are different between those with a winch and those without a winch. Therefore, when a winch is later mounted on a vehicle without a winch, the mounting portion must be specially provided, so that it cannot be easily mounted and the cost is greatly increased.

The present invention has been made in view of the above points, and the winch or its related parts do not protrude forward of the vehicle, so that an increase in the number of parts, an increase in weight, and an increase in price can be suppressed as much as possible. It is an object of the present invention to provide a four-wheeled all-terrain vehicle equipped with a winch mounting structure that allows easy mounting of a winch.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, a four-wheeled all-terrain vehicle according to the present invention is provided with a front guard connected to a body frame at a front portion of the vehicle. In a wheeled terrain vehicle, a guide roller mechanism for an electric winch and a tow rope (a winch rope) is arranged in this order from the rear to the front at a lower portion in the front guard.

According to the riding type four-wheel uneven terrain vehicle of the present invention having the above configuration, the guide roller mechanism of the tow rope and the electric winch are provided in the front guard and are exposed to the outside. Unlike the conventional case where the winch protrudes to the front of the vehicle, it does not hinder driving and protects the winch without providing any special protective member such as a winch guard. In addition to being able to do it, it has excellent appearance. Moreover, since the front guard is connected to the front end of the vehicle body frame, the winch and the guide roller mechanism can be protected even if an obstacle such as a tree branch or a rock hits the front guard.

The front guard is connected to the left and right lower frames of the vehicle body frame, and the left and right lower members extending forward from the connection portion, and upward from the lower member. It comprises left and right front members extending and a lower connecting member connecting the left and right lower members, and the winch mounting member can be integrally attached to the lower connecting member.

According to the riding type four-wheel uneven terrain vehicle of the present invention, since the winch mounting member is provided by utilizing a part of the front guard as a strength member, the increase in weight and the number of parts is minimized. And the manufacturing becomes easy. Further, since the winch can be mounted on the above-mentioned mounting member without using a dedicated mounting member, the vehicle can be easily changed to a vehicle with a winch even after purchasing a vehicle without a winch.

According to a third aspect of the present invention, in the riding type four-wheel uneven terrain vehicle of the second aspect, the guide roller mechanism of the winch is disposed in front of the winch and is detachably attachable. It is desirable to provide a mounting member integrally with the winch mounting member.

According to the riding type four-wheel uneven terrain vehicle of the third aspect, the guide roller mechanism for guiding the tow rope can be easily arranged without adding any special parts.

As set forth in claim 4, claim 2 or 3
The winch is provided between a lower portion of a radiator for engine cooling water provided at a front portion in the vehicle body frame and the lower connecting member, and a wind guide is provided above the winch. Preferably, a plate is arranged from the front member to the lower part of the radiator.

According to the fourth aspect of the invention, the winch can be attached to the front portion of the vehicle without obstructing the passage of the cooling air from the front of the vehicle to the radiator. In other words, the winch is provided between the lower connecting member that connects the lower part of the radiator and the left and right lower members of the front guard, and it is not on the front of the radiator, and the wind guide plate is provided above the winch. ,
Since the cooling air guided from the front of the vehicle body to the radiator is guided almost straight to the radiator, the cooling performance is not hindered by a winch or the like.

The winch is less likely to interfere with driving, and there is no need to provide a special guard at the front. In addition, the front guard is connected to the front end of the body frame, so it is stiff and strong, and even if obstacles such as tree branches or rocks hit the front guard, the electric winch and guide roll mechanism can be used. Protected.

(2) According to the second aspect of the present invention, since the winch mounting member is provided by utilizing a part of the front guard as a strength member, an increase in weight and the number of parts can be suppressed to a minimum. Manufacturing is also easier. Further, since the winch can be attached to the above-mentioned attachment member without using a dedicated attachment member, even if a vehicle without a winch is purchased, it can be easily and inexpensively changed to a vehicle with a winch.

(3) According to the third aspect of the present invention, the guide roller mechanism for guiding the tow rope can be easily arranged without adding a special part.

(4) According to the fourth aspect of the invention, the winch is provided between the lower connecting member connecting the lower part of the radiator and the left and right lower members of the front guard, and is not provided on the front surface of the radiator, but is provided on the winch. Since the air guide plate is provided above, the cooling air for leading to the radiator from the front of the vehicle body can be led straight and directly to the radiator, so that the cooling performance is not hindered by a winch or the like.
