Problems solved by technology

[0004] However, in the conventional structure, since the rotation sensor is provided on the gear that moves in the axial direction of the transmission, it is necessary to increase the axial width dimension of the gear, or use an expensive sensor with high detection sensitivity, so that even the gear Movement can also detect the rotational speed of the gear

Abstract

The invention relates to an internal combustion engine, which harbors a crankshaft and a transmission in a crank case; wherein the transmission is provided with a plurality of gears for gear shift; furthermore, the transmission is provided with an input shaft for inputting the rotary power of an input crankshaft and an output shaft for transmitting the rotary power of the crankshaft through the gear from the input shaft and further transmitting the rotary power to a driving wheel. Rotation detection devices (401, 402) for detecting the rotating speed of the transmission and the gears (49c, 49d) with fixed axial position which are linked with the input shaft (28) oppositely configure detection parts (401a, 402a) of the rotation detection devices. Hence, the internal combustion engine with the rotation detection devices can detect the rotating speed of the transmission gear without increasing the axial width dimension of the gear, applying expensive sensors with high detection sensitivity or restricting the degree of freedom of the configuration of a variable-speed drum.

Description

technical field [0001] The present invention relates to an internal combustion engine having a rotation detection device for detecting the rotational speed of a gear of a transmission. Background technique [0002] Such a rotation detection device is known (for example, refer to Patent Document 1). A transmission having a plurality of gears (rotating bodies) on the shaft is provided behind the crankcase, and the rotation detection device moves axially with one of the plurality of gears of the transmission. A rotation sensor is correspondingly provided for the gear, and the rotation sensor detects the rotation speed of the gear, thereby detecting the rotation speed of the shaft of the transmission. [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2000-87780 [0004] However, in the conventional structure, since the rotation sensor is provided on the gear that moves in the axial direction of the transmission, it is necessary to increase the axial width dimension of ...
