Problems solved by technology

[0007] However, for a small vehicle such as a two-wheeled motor vehicle in which the upper part of the engine crankcase on the power plant is supported on the vehicle body frame so as to be able to swing up and down, if the control unit is installed on the throttle body device, it is not only necessary to reduce the transmission from the engine to the control unit. vibrating damper, and since the throttle body unit rocks up and down with the powerplant, the load required on said damper also tends to be greater

Abstract

In a small-sized vehicle in which in the rear of a power unit composed of: an engine which is arranged forward of a rear wheel and in which an upper part of a crankcase is rockably supported by a body frame; and a transmission for speed-changing output from the engine to transmit to the rear wheel, the rear wheel is axially supported, and an air cleaner to be mounted to the transmission is connected to a cylinder head of the engine through a throttle body device comprising a throttle valve fixed to a valve shaft to be supported pivotally by a body having an intake passage, vibration reaching the control unit will be reduced and a load to be applied to members for reducing the vibration will be reduced. The throttle body device 27, in which the control unit for controlling an operation of the engine E is installed to the body with the elastic member 28 interposed with the cylinder head 30 is arranged forward of a rocking supporting point SP of the upper part of the crankcase 22 with respect to the body frame 11.

Description

technical field [0001] The present invention relates to a small vehicle such as a two-wheeled motor vehicle and a three-wheeled motor vehicle, and more particularly, to an engine including an upper part of a crankcase which is arranged in front of a rear wheel and is supported by a vehicle body frame so as to be rockable, and a motor for the The rear part of the power unit of the transmission that transmits the output of the engine to the rear wheel after shifting the output of the engine, the rear wheel is supported by the shaft, and the air filter mounted on the transmission is rotatably supported by the air filter having an intake passage. The throttle body device is formed by fixing the throttle valve on the valve shaft on the main body, and is connected to the improvement of the small vehicle of the engine cylinder head. Background technique [0002] In the rear part of the power plant including the engine arranged in front of the rear wheels, the upper part of the cran...
