よシ種々のマウントゴムが開発されている。(Prior art) Generally, the engine body, which is the power unit of an automobile,
While generating/generating minute vibrations during idling, etc.
During driving, large vibrations occur due to road reaction forces and rapid fluctuations in drive torque, and this phenomenon occurs more noticeably in front-wheel drive transverse engine vehicles than in FRJILKs. Conventionally, various mounting rubbers have been developed for power units having such vibration characteristics.

不快感を与えるという問題がある。(Problem to be solved by the invention) However, if the former is adopted and the
Even if full vibration absorption is achieved, it is not possible to suppress the shaking of the power unit while driving, and as a result, the excessive shaking of the power unit causes exhaust system parts to interfere with the vehicle body, reducing its durability. There is a problem with negative effects. Furthermore, if the latter is adopted, even if the shaking of the power unit during driving can be suppressed to a small level, there is a problem that vibration absorption cannot be ensured, and as a result, the occupant feels uncomfortable.
このようなことから、パワーユニットの振動特性に対応

れる。(Means for Solving the Problems) The technical means of the present invention is to provide a stopper member on one side of the mount rubber interposed between the engine body and the vehicle body in the displacement direction, and to provide a stopper member on the other side of the mount rubber. A stopper rubber that abuts against the stopper member is provided, and this stopper rubber is
The abutting end portion on the stopper member side is formed to be tapered, and a hollow member is provided inside the stopper rubber. The material of the hollow member may be metal or non-metal, but if it is made of qIfK resin, softer nonlinear spring characteristics can be obtained as a composite characteristic of rubber and resin.

体の揺動量を小さく抑えることができない。(Function) In this way, by forming the abutting tip of the stopper rubber into a tapered seam shape and embedding a hollow member in the stopper rubber, both the effect of preventing shaking of the engine body and the vibration absorption properties are improved. be satisfied. This will be explained using figures together with comparative examples. If the stopper rubber 12 is made into a rectangular shape and the amount of build-up is increased as shown in FIG. 9, the spring characteristics become linear with high vibration damping properties as shown in graph A of FIG. 12, but the spring constant at the rise Since the vibration absorption is high, vibration absorption is poor, and the amount of deflection is large, resulting in a large amount of rocking of the engine body. !
9. If the stopper rubber 12 shown in FIG. 10 is formed into a tapered shape with its abutting tip end facing in the direction of elastic displacement However, since the amount of deflection is almost as large as that of the stopper rubber 12, the amount of rocking of the engine body cannot be kept small.

R, Q, P? As shown by the passing graph C, the slope changes in three stages. That is, the rising spring constant is low, and the spring constant gradually increases and the amount of deflection decreases. Therefore, good vibration absorption properties are ensured, and the amount of rocking of the engine body can be suppressed to a small level. By changing the thickness and size of the hollow member 14, graph C in FIG. 12 can be shifted to the left in the figure and set to graph C, which corresponds to the vibration characteristics of the engine body. The desired nonlinear spring characteristics can be obtained.

る。In the embodiment having such a configuration, the power unit 1 rolls around the rotation center 0 when the vehicle starts and changes speed. The reaction force of the drive system torque generated at this time excites the power unit 1. In response to this, the front side mount rubber 2 is elastically deformed between the power unit 1 and the frame 5 of the vehicle body, so that the upper stopper metal fitting 7
violently slams the stopper rubber 12t (see Figure 8). In the conventional structure, the resulting vibration was propagated to the instrument panel and steering wheel, causing discomfort to the driver, but in this embodiment, the upper metal fitting 7 of the stopper rubber 12
Since the tip that abuts against the wheel is tapered, the spring constant at startup is low, and minute vibrations at the time of starting are well absorbed and eliminated.

Since the amount of deflection is small, the shaking of the power unit 1 can be reliably suppressed to a predetermined value or less.

ことができる。(Effects of the Invention) As described above, according to the present invention, since the hollow member is provided inside the tapered sill-shaped stopper rubber, it is possible to easily obtain nonlinear spring characteristics that match the vibration characteristics of the engine body. Sufficient vibration absorption of the engine body is ensured, improving driver integrity, and the amount of shaking of the engine body can be reliably regulated to a smaller value than before, preventing interference between exhaust system parts and auxiliary parts and the vehicle body. There is an effect that can be achieved. Moreover, according to the present invention, the structure is simple and easy to manufacture, and by appropriately selecting the size and material of the hollow member, the spring constant of the stopper rubber can be arbitrarily set within a wide range.
