Description

Description: TECHNICAL FIELD The present invention relates to a motorcycle, and more particularly to a motorcycle having a front wheel at a front end of a swing arm extending forward from a center portion of a vehicle body.

[Conventional technology]

As this type of motorcycle, for example, Japanese Patent Publication No. Sho 58-49435.
There is one shown in Japanese Patent Publication. Brackets are fixed on both front and rear sides of an engine unit with an engine and gearbox, etc., and swing arms that support the front wheels with the front brackets, and rear wheels with the rear brackets are supported. A steering wheel is connected to a bar handle supported by a tripod mounted on an engine unit via a universal joint to steer the front wheels, and a body frame having a conventional head pipe is adopted. Compared to motorcycles, the body frame is simplified and the weight of the vehicle is greatly reduced.

[Problems to be solved by the invention]

However, in the above motorcycle, the swing arm swings up and down and the front wheels are steered left and right, so that it is difficult to attach the front fenders that follow the movement of the front wheels.

Therefore, an object of the present invention is to provide a motorcycle equipped with a front fender that follows the movement of the front wheels.

[Means for solving problems]

In order to achieve the above object, the present invention provides a motorcycle in which a front wheel is steerably supported via a knuckle arm provided between front ends of a pair of upper and lower swing arms extending forward from a vehicle central portion, in the knuckle arm, The feature is that a fender that covers the upper part of the front wheel is fixed.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

The motorcycle 1 supports a swing arm 4 supporting a front wheel 3 so as to be vertically swingable on a front portion of side frames 2 fixed to both sides of an engine unit integrally formed with an engine and a gear box. .

The swing arm 4 has one end 5a of the upper arm 5 and one end 6a of the lower arm 6 rotatably pivoted to the side frame 2, respectively, and an upper part 7a of the knuckle arm 7 supporting the front wheel 3.
The tip of the upper arm 5 is connected by a joint 8 and the tip of the lower arm 6 is connected by a joint 9 to the lower portion 7b of the knuckle arm 7.

Bracket fixed above the front of the side frame 2
A handle support member 11 is provided on the handle 10, and a bar handle 12 is rotatably supported on the handle support member 11.

A connecting rod is attached to the shaft 13 of the bar handle 12 via a lever (not shown) protruding rightward in the vehicle width direction.
14 is connected, and the rear end 14a of the connecting rod 14 is connected to the steering arm 18 via levers 16 and 17 supported by a shaft 15 penetrating the side frame 2 in the vehicle body width direction,
The front end 18a of the steering arm 18 is connected to the intermediate portion 7c of the knuckle arm 7 via a joint 19, whereby the front wheel 3 is steered by operating the bar handle 12.

A fender 20 that covers the upper portion of the front wheel 3 is fixed to the knuckle arm 7. This fender 20 has an engaging projection 20b formed on the upper surface of a fender portion 20a that covers the upper portion of the front wheel 3, and a mounting portion 20c that hangs down the lateral side of the fender portion 20a. The engaging projection 20b is locked in the hole 7a, and the mounting portion 20c is screwed to the rear surface 7d of the knuckle arm 7 with screws 21 and 21 and fixed to the knuckle arm 7.

With this configuration, the fender 20 has the front wheels 3
The upper part of the front wheel 3 can be covered following the movement of the fender 20 and the mounting span of the fender 20 can be increased.

〔The invention's effect〕

INDUSTRIAL APPLICABILITY As described above, the present invention provides a motorcycle in which a front wheel is steerably supported via a knuckle arm provided between front ends of a pair of upper and lower swing arms extending forward from a central portion of the vehicle. Since the fender covering the upper part of the is fixed, the fender that follows the movement of the front wheels can be attached with a simple structure.
