Abstract

The present invention relates to a saddle-type vehicle including rotary electric machine which has little effection to the position of the crankcase, and the output character can be changed by changing the magnetic field intensity mechanically. The saddle-type vehicle comprising a crankcase housing the crankshaft, a crankcase cover attached to a side of the crankcase, and a rotary electric machine housed in the crankcase cover and connected to the crankshaft, wherein the rotary electric machine has a magnetic field varying mechanism for varying the intensity of a magnetic field in the rotary electric machine to change the output characteristics of the rotary electric machine, wherein the saddle-type vehicle further comprises an operation mechanism connected to the magnetic field varying mechanism for transmitting power to operate the magnetic field varying mechanism, and wherein the operation mechanism is supported by the crankcase cover.

Description

technical field [0001] The present invention relates to a straddle type vehicle equipped with a rotating electrical machine with variable output characteristics, and more particularly, to the layout of the straddle type vehicle. Background technique [0002] In the field of straddle-type vehicles including motorcycles, vehicles equipped with rotating electrical machines not only serving as generators but also mounted on crankshafts to assist power of engines have been developed. [0003] Generally, due to the structure of a rotating electrical machine, output characteristics such as rotation speed and torque of the rotating electrical machine are limited within a narrow range. For example, a rotating electrical machine that has field magnets that generate strong magnetic flux and can rotate at high torque cannot be driven at low torque and high speed, and a rotating electrical machine that can rotate at low torque and high speed cannot be driven at high torque and are drive...
