Abstract

PURPOSE:To aim at the vibro-damping of car vibrations, by installing an elastic body, in a state of being compressed by as far as the desired value, between both output and input arms, and connecting both output and input members rotatably with each other in a relative manner. CONSTITUTION:An elastic body 11 directed in the circumferential direction is installed between an output arm 4 and an input arm 7 in a state of being compressed as far as the desired value, connecting an output member 1 and an input member 6 rotatably with each other in a relative manner. And, there is provided with a friction plate 12 which gives friction damping force to the relative rotation between both these output and input members 1 and 6. Here, the elastic body 11 is constituted of a coil spring consisting of a large diametral spring 11a bearing main spring force and a small diametral spring 11b. The large diametral spring 11a has its free length in which initial deflection load is released before the relative rotation reaches the maximum turning angle and the spring force is lost, while free length of the small diametral spring 11b is set to such a size that does not lose the spring force even at the maximum turning angle. In consequence, car vibrations can be effectively absorbed and damped.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a latch disk that is suitable for use in automobile clutch devices and the like.

In automobiles, vibrations in the drive system caused by fluctuations in engine torque induce vibrations throughout the vehicle, and these vibrations are caused by large transient changes in engine torque, such as during sudden acceleration or deceleration, and the level of vibration increases. If it is high, it will cause discomfort to the passengers.

Therefore, the present inventor has been conducting research on measures to prevent this type of vehicle vibration, particularly vibration in the drive system, and one of the methods is to absorb this vibration by changing the torsional rigidity of the clutch disc, and to We are considering a configuration that suppresses vibration transmission.

However, according to the inventor's detailed study, the initial objective cannot be achieved by simply changing the torsional rigidity of the clutch disc, and in order to achieve this, the torsional rigidity must be set to the characteristics described below. It turned out that it was necessary. In other words, among clutch discs whose torsional stiffness changes stepwise or non-linearly, those whose stiffness increases from the middle have a smaller anti-vibration effect than those whose stiffness increases from the middle, and vice versa. When the characteristics decrease, the amount of vibration transmitted decreases and the vibration isolation effect is large.

The present invention provides an output member having a plurality of output arms protruding radially outward from a boss portion, and an input arm disposed between the output arms circumferentially extending radially inward. A protruding input member is provided, and an elastic body compressed by a desired amount is housed between the output arm and the input arm to connect the output member and the input member so as to be relatively rotatable, thereby increasing torsional rigidity. The structure is such that it has a characteristic that decreases halfway.

[Operation] When the output member and the input member are rotated relative to each other by more than a predetermined amount, one of the paired elastic bodies housed between the output arm and the input arm reaches its free length, and the elastic body given by the initial deflection reaches its free length. The initial load becomes zero. As a result, the overall spring constant obtained when both of these pair of elastic bodies act as a spring becomes larger than the spring constant when only one acts as a spring, and the torsional property that the tearing stiffness decreases halfway is suppressed. to improve the anti-vibration effect.
