Problems solved by technology

[0006] However, as in the prior art, when the rotation shaft of the valve drive motor is arranged along the vehicle width direction, the valve drive motor protrudes outward in the vehicle width direction.
As a result, there is a problem that the valve driving motor protrudes in the lateral direction of the vehicle, resulting in an increase in vehicle width.

no. 1 approach

[0072] figure 1 It is a left side view showing the overall configuration of a motorcycle (a saddled vehicle) 1 to which the first embodiment of the present invention is applied. Such as figure 1 As shown, the motorcycle 1 of the present embodiment has a body frame 2 composed of a main frame 3 and a rear frame 4 . The main frame 3 is joined to the rear side of the head pipe 5 by welding, and extends obliquely from the head pipe 5 toward the rear and downward. The rear frame 4 is joined to the rear end of the main frame 3 by welding. The main frame 3 and the rear frame 4 are formed of steel pipes. The main frame 3 may be formed in a shape such as a substantially circular cross section, an I-shape, or a U-shape opening downward. The main frame 3 can also be formed using an aluminum casting or the like.

[0073] A left and right pair of front forks 6 are installed below the head pipe 5, and the front forks 6 can steer freely. Front fork 6 pivotally supports front wheel 7 and...

no. 2 approach

[0097] Below, refer to Figure 4 , Figure 5 A second embodiment will be described. Figure 4 It is a left side view of the periphery of the engine 13 of the motorcycle 1 in the second embodiment. The overall structure of the motorcycle 1 in this second embodiment is the same as that of the first embodiment, and the same reference numerals are assigned to the same components as those of the first embodiment, and description thereof will be appropriately omitted.

[0098] In the first embodiment, the throttle unit 20 is configured to be supported by the main frame 3 , but in the second embodiment, the throttle unit 20A is configured to be supported by the intake chamber 17 . In addition, the internal structure of the throttle unit 20A is the same as that of the throttle unit 20 of the first embodiment, and description thereof will be omitted.

[0099] The throttle valve unit 20A is arranged so as to overlap with the intake chamber 17 in a side view. The air intake chamber 1...

no. 3 approach

[0106] Below, refer to Figure 6 , Figure 7 A third embodiment will be described. Figure 6 It is a left side view of the periphery of the engine 13 of the motorcycle 1 in the third embodiment. In the first embodiment, the air intake chamber 17 is disposed behind the head pipe 5 and below the main frame 3 , but in this third embodiment, the air intake chamber 117 is disposed in front of the head pipe 5 . Structure. According to this structure, by arranging the intake chamber 117 in front of the head pipe 5, the distance between the intake chamber 117 and the throttle body 200 can be separated, and the connection pipe 121 connecting the intake chamber 117 and the throttle body 200 can be made The length of the suction pipe becomes longer, so that the low-speed torque can be increased.

[0107] In this third embodiment, the overall configuration of the motorcycle 1 is the same as that of the first embodiment except for the arrangement configuration of the air intake chamber...

Abstract

The invention provides a bestride type vehicle, which can inhibate a valve driven motor from protruding outside from the width direction of the vehicle, and the structure is compact. The bestride type vehicle possesses the components as following: a head pipe (5), with which the bearer of a rotary device is rotatable; a main frame (3), which is formed by a frame extending from the head pipe to the back and lower direction; a motor (13), which is supported by the main frame, wherein the motor possesses a crankcase (14), a cylinder (15) protruding forward from the crankcase and a cylinder cover (16); absorbing tubes (19, 119) which extending upward from the upper portion of the cylinder cover; a throttle (201) which is equiped at the middle of the absorbing tubes for adjusting the air amount providing for the engine; and a valve driving motor (220), which drives the throttle corresponding to the input of the operation member operated by a driver. The bestride type vehicle is characterized in that the rotary shaft (202) of the throttle and the rotary shaft (201) of the valve driven motor are extendint up and down along the vehicle body and are parallel with each other.

Description

technical field [0001] The present invention relates to a saddled vehicle including a throttle valve and a valve drive motor that drives the throttle valve. Background technique [0002] Conventionally, in a saddled vehicle such as a motorcycle having an engine supported by the lower portion of the main frame extending rearward and downward from the head pipe, an intake pipe for supplying air to the engine is provided from the upper portion of the cylinder head toward the upper front. A throttle valve for adjusting the amount of air supplied to the engine is disposed on the intake pipe. The throttle valve is an electric throttle valve controlled to open and close in response to an input from an operating member operated by a passenger, and includes a valve drive motor for driving the throttle valve (for example, refer to Patent Document 1). This type of throttle valve is arranged such that the rotation axis of the throttle valve is along the vehicle width direction, and air...
