モードと同様の傾向を有するものである。 As is well known, an automobile power plant consists of an engine and a transmission that is integrally connected to the engine, and the output shaft of the transmission is connected to the drive wheels via a propeller shaft and a differential. ing. The power plant usually vibrates due to unbalanced inertia of the engine or unbalanced propeller shaft, which causes noise and impairs riding comfort. For convenience, this will be explained with reference to FIG. 1, which shows an embodiment of the present invention. In the figure, 10 is the main body of a truck diesel engine, and 12 is a diesel engine that is fastened to the engine main body by bolts. A flywheel housing, 14 a transmission device also fastened to the flywheel housing with bolts, 16 a center brake mounted on the rear end output shaft of the transmission device 14,
The output shaft is connected to a propeller shaft via a universal joint (not shown). The vibration mode of the power plant is as shown in FIG.
The rear end vibrates significantly. This vibration mode varies in size in each part depending on the individual power equipment, and even in the same power equipment, the vibration mode differs in size in the vertical direction and in the horizontal direction (generally, the vibration mode in the vertical direction The frequency Fv of the vibration is larger than the frequency Fh of the vibration in the left-right direction), and has approximately the same tendency as the mode illustrated in FIG.

A ring-shaped inertial mass is attached via rubber,
The gist of the present invention is a vehicle power device characterized in that the spring constant of the rubber is set to be relatively large in the vertical direction and small in the horizontal direction. According to the present invention, as already explained with reference to FIG. 2, a ring-shaped inertial mass is attached via rubber to the outer periphery of the transmission housing near the end of the transmission housing on the side farthest from the engine, where vibration is greatest. Furthermore, the rubber is tuned so that it has a relatively large spring constant in the vertical direction, where the vibration frequency is high, and a relatively small spring constant in the horizontal direction, where the vibration frequency is lower, so that the power including the engine and transmission It is possible to effectively suppress the vibration of the device, reduce noise, and improve riding comfort.

心地を改善することができる。 Embodiments of the present invention will be described in detail below with reference to FIGS. 1 and 3 to 5. First, according to the present invention, as shown in FIG. 1, a damper device 18 is attached to the outer peripheral portion of the housing 14' of the transmission 14 near the rear end. In the first embodiment of the present invention shown in FIG.
is press-fitted to the outside of the rear end of the housing 14',
Alternatively, an inner sleeve 20 that is fitted and fixed to the housing with bolts or the like, a ring-shaped inertial mass 22 that is arranged concentrically with respect to the inner sleeve 20, and a space between the inner sleeve 20 and the ring 22. The rubber member 24 has a cocoon-shaped cavity 26 in the left-right direction in this embodiment, and the spring constant in the vertical direction is higher than the spring constant in the left-right direction. It is designed to be large in size. (In addition, the same rubber member 2
4 is, of course, made of a rubber material or a synthetic resin material having elastic properties equivalent to rubber material. ) Therefore, as already explained with reference to FIG. 2, the spring constant of the rubber member 24 should be tuned in advance in accordance with the vibration modes of the engine 10 and transmission housing 14' in the vertical and horizontal directions. Accordingly, it is possible to effectively reduce vibration of a power device including an engine and a transmission, reduce noise, and improve riding comfort.

である。 Next, the second embodiment of the present invention shown in FIG. 4 has a plurality of cylindrical holes (in the illustrated case, three In this embodiment as well, the spring constant in the vertical direction is appropriately larger than that in the horizontal direction to effectively reduce vibrations of the power unit including the engine 10 and the transmission 14. I can do it. Furthermore, FIG. 5 shows a third embodiment of the present invention, in which the vertical portion 24a of the rubber member 24 is formed thicker than the horizontal portion 24b, so that the spring constant in the vertical direction is changed from the horizontal spring constant. This is set relatively larger than the spring constant. In this embodiment as well, as in the first embodiment, it is possible to effectively reduce the vibration of the power plant, reduce noise, and improve riding comfort. Furthermore, in common to each of the above embodiments, the ring 22 serving as the inertial mass
However, since the ring 22 is fitted around the outer periphery of the transmission housing 14', even if the rubber member 24 should be damaged, the ring 22 may fall off and collide with another vehicle, causing a major accident. It is safe and has no problems such as.
