Abstract

PURPOSE:To reduce the manufacturing processes and reduce the cost through the decreased number of parts by adding a dog clutch as a part of the power transmission device set in a crank case and by switching from the four-wheel drive to the two-wheel drive using this clutch. CONSTITUTION:In the center bottom of a crank case 8, an output shaft 31 to drive the front wheels is set, and at the other end of this output shaft 31 a driven bevel gear 40 is fixed, and the gears 40, 41 constitute a bevel gear transmission mechanism 42. In an engine 7, the power of a crank shaft 10 is transmitted to a main shaft 15 through a driven gear 14 and then transmitted to driven gears 22, 23 supported on a counter shaft 21. Between this counter shaft 21 and the driven gear 23, a power transmission on/off clutch mechanism 50 is set, and this mechanism 50 is equipped with a dog clutch 51. Controlling this dog clutch 51 to disengage the counter shaft 21 from the gear 23, the two-wheel drive system is effected.

プの要因となっていた。In general, a four-wheel drive vehicle does not drive only all wheels at all times (used only as a so-called full-time four-wheel drive vehicle), but instead operates as a four-wheel drive vehicle when driving on rough terrain. It drives all wheels, and switches between four-wheel drive and two-wheel drive depending on the vehicle's driving conditions, such as driving only the front or rear wheels as a two-wheel drive vehicle on flat roads.
It is used as a so-called part-time four-wheel drive vehicle. By the way, in conventional part-time four-wheel drive vehicles,
A single device such as a hydraulic clutch is used as the power transmission switching device to switch between the four-wheel drive system and the two-wheel drive system, and this is interposed between the power train between the axle shaft that connects and disconnects the driving force and the engine. I was trying to let him do it. Therefore, in the conventional power transmission switching device described above,
A special case and parts are required to accommodate this, so
The number of parts was large, and the assembly process was complicated, leading to increased costs.
