Abstract

PURPOSE:To reduce vibration an noise and prevent crack initiation and breakage in/of assist machines or the like by coupling the assist machines directly with a crank shaft using a belt transmitting mechanism installed at the tail of an engine, and thereby suppressing amplified vibration at the head of the engine and vibrations of the assist machines themselves. CONSTITUTION:In a power transmission device according to the present invention, a transmission case 38, transfer case 39, etc., are installed in line at the side of the engine 31, so that the coupling rigidity of power plant is heightened, and booming noise likely at high speed revolutions of engine can be suppressed satisfactorily. An alternator 54 is installed at the outer side of a chain case 35, and a rotor 58 is coupled directly with the output shaft 45, so that the weight on the front side of the engine is reduced, and rotation of the alternator 54 is transmitted directly from the crank shaft 31a. Accordingly the amplified vibration can be suppressed sufficiently, and vibration of the alternator itself 54 be suppressed. This prevents generation of large vibratory sounds and also crack initiation and breakage in/of an alternator casing 55.

Problems to be Solved by the Invention As described above, in the conventional power transmission device, by attaching the transmission 3 and the transfer 4 to the side of the engine 1, the joint rigidity of the power plant is increased, and the lowest Although the natural frequency of the engine is low (and the muffled noise at high rotation speeds can be sufficiently suppressed, the weight of the front end of the engine increases because multiple auxiliary equipment such as the alternator 25 are concentrated on the front end of the engine 1). Excessively amplified vibrations occur near the alternator 25 in the engine front and back and in the width direction (in the direction of the arrow) while the engine 1 is running due to the tensile force of the transmission belt 27.As a result, large vibration noise or vibrations are generated inside and outside the vehicle. As the vibration propagates, there is a risk that the excessive vibration may cause cracks or damage to auxiliary equipment.

Therefore, according to this embodiment, since the transmission case 38, transfer case 39, etc. are attached in parallel to the side of the engine 31, the coupling rigidity of the power plant is increased, and the muffled noise at high engine speeds is reduced. Not only can this be sufficiently suppressed, but since the alternator 54 is attached to the outside of the chain case 35 and the rotor 58 is directly connected to the output shaft 45, the weight on the front end side of the engine 31 is reduced, and the rotational force of the alternator 54 is transferred to the crankshaft.

Furthermore, since the belt transmission mechanism 42 is directly connected to the crankshaft 31a, fluctuations in the rotational torque of the crankshaft 31a are first absorbed by the moment of inertia Ip generated by the belt transmission mechanism 42 such as the drive chain 50, and then by the flywheel 5.
1, the moment of inertia IPr generated is absorbed. That is, the minimum moment of inertia (2) required to absorb torque fluctuations is generated by the belt transmission mechanism 42 in addition to the flywheel 51.
It is also possible to divide IPI into IPI and 1. ,
Since the sum of c can be satisfied, the outer diameter and wall thickness of the flywheel 51 can be reduced to the necessary minimum. As a result, it is possible to reduce vehicle weight and manufacturing costs.

Furthermore, as described above, since the moment of inertia IPI of the belt transmission mechanism 42 is added in advance as part of the required moment of inertia JP+, the generation of an unnecessary moment of inertia is prevented, and therefore the main shaft 33c rotates synchronously with the crankshaft 31a. Therefore, it becomes possible to smoothly switch gears.
