Description

Technical Field [0001] The present invention relates to a Vibration Reduction Device for Transmission Test,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration reduction apparatus for a transmission test, and more particularly, to a vibration reduction apparatus for a transmission test, in which a headstock holding a transmission and a drive motor for driving the transmission are separated, To a vibration reduction device for a transmission test.

Generally, the torque generated from an automobile engine is almost constant regardless of the change in the rotational speed, and the output has a characteristic that the output varies greatly depending on the rotational speed.

The driving force required when the vehicle travels greatly changes depending on the road conditions and the traveling speed in the state in which the passenger and the cargo are loaded. Therefore, a device for changing the torque between the engine and the driving wheel is required in order to cope with this situation. The same device is called a transmission.

The transmission is largely divided into a manual transmission, an automatic transmission, and an automatic manual transmission.

The manual transmission is a transmission in which the driver manually changes gears. In the case of shifting, it is difficult to shift in the case of an untrained driver because it is necessary to separate the shift actuator and the engine with a clutch and then transfer the power to the clutch again after changing the gear.

However, those who want quick response or high fuel economy prefer a manual transmission because they can make better use of the engine's capabilities compared to cars equipped with automatic transmissions.

The automatic transmission is a transmission that literally shifts automatically. The torque converter, which plays an important role among them, is a device that increases the power interruption and torque by the fluid flow.

The automatic transmission changes the transmission gear automatically according to the predetermined shift pattern according to the degree of depression of the accelerator pedal and the vehicle speed, and this process is performed by the hydraulic device.

Recently, a double clutch transmission (DCT) has been provided which combines the advantages of a manual transmission and an automatic transmission.

Unlike the conventional single-plate clutch transmission system, the double-clutch transmission is composed of two clutches, the first clutch interrupts the hole means gear, and the second clutch is a transmission system designed to intermittently control the even- And it is advantageous in that the fuel economy improvement effect can be obtained higher than that of the automatic transmission vehicle.

In addition, since the double clutch transmission does not have an acceleration stop sensation generated in the single plate clutch transmission, the transmission feeling is also very advantageous.

As a result, the automobile industry has begun mass production with the development of a double-clutch transmission, and the demand for performance testing equipment after final assembly is increasing, as in the automatic or manual transmission production line.

In order to drive the transmission in such a performance testing apparatus, an input-side drive device that rotates in engagement with the transmission and an output-side power absorption motor for applying a load such as a running state of the vehicle to the transmission are provided.

Fig. 1 is an overall configuration diagram showing a conventional automotive transmission tester, and Fig. 2 is a partial configuration diagram of a conventional automotive transmission tester.

1 and 2, the conventional transmission testing machine includes an input side motor 20 for driving the transmission 10 on the upper surface of the bed 1, an output side power absorbing unit 20 for applying a load to the transmission 10, The motors 30 are installed symmetrically with respect to each other.

A head stock 22 for holding the input side motor 20 and the transmission 10 is provided on the upper surface of the bed 1. The input side motor 20 and the head stock 22 are connected to one base plate 5, Respectively.

The vibration generated in the transmission 10 rotated by the input side motor 20 is transmitted to the head stock 22 and the vibration applied to the head stock 22 is transmitted to the base plate 5 And the vibration generated by the rotation of the input side motor 20 is also applied to the base plate 5.

As a result, the vibration of the input side motor 20 and the vibration transmitted to the headstock 22 are applied to the base plate 5 to increase the vibration. In addition to the increase in noise due to such vibration, The power transmitting member, the output side power absorbing motor 30, and the like are destroyed.
