The present invention relates to a transmission that is a power transmission device of an automobile, and in particular, after installing a diaphragm in a gear shaft lever of a manual transmission vehicle, sensing a voltage according to the number of revolutions of an engine and vibrating the diaphragm by driving a motor when the voltage is higher than a predetermined voltage. In this regard, the present invention relates to a gear shift timing notification device for a manual transmission vehicle that automatically informs a driver of a gear shift timing.

In general, a car has a complicated structure, but the car is divided into a chassis and a body, and a chassis is a main part of a car, and a power generator, a power train, a driving device, a steering device, It consists of an auxiliary device and refers to everything except the body of the car.

The power transmission device from the engine to the drive wheel is a clutch for transmitting or blocking power to the drive wheel, and the power transmitted through the clutch at a speed and driving force suitable for the driving state of the vehicle. A transmission that changes, a long shaft that receives rotational force from the transmission and transmits it to the final reduction gear, a drive line connected by a universal joint, and transmits power in a direction perpendicular to the propulsion shaft, while increasing torque at a constant reduction ratio. Final reduction gear that decelerates by speed reduction, and differential gear that automatically adjusts the rotation of left and right wheels differently when driving a curve or driving uneven road surface. diffrential gear system), the power transmitted from the differential gear is transmitted to the drive wheel via the drive shaft It consists of drive axle and wheel.

On the other hand, the transmission (transmission) is installed between the engine and the propulsion shaft or between the engine and the differential gear to change the power of the engine to the rotational force and speed according to the driving state of the vehicle to the driving wheels (transmission) is a manual transmission (manual transmission) and There is automatic transmission, which is necessary to increase torque and no load at start-up or to back up the car, so it has good transmission efficiency, continuously shifted without steps, easy to operate, fast, reliable and quiet Should be small, light weight, trouble free and easy to handle.

In a vehicle equipped with a manual transmission as shown in FIG. 1, gears should be shifted according to the gear shift timing for smooth driving and fuel saving. However, it is difficult for a novice driver to accurately determine the gear shift timing. There was a point.

In order to solve such a problem, after installing a warning light on the instrument panel, a warning light is turned on when the engine RPM (RPM) exceeds a certain number of revolutions, and a method of informing the driver of the gear shift time has been devised.

However, the conventional gear shifting time warning device such as Aesop has a problem that it is difficult for a novice driver to check the lighting state of the instrument panel while driving, and misses the shifting time so that smooth driving cannot be performed.

Therefore, the present invention was devised to solve the conventional problems as described above, and after the diaphragm is installed in the gear shift lever of a manual shift vehicle, sensing the voltage according to the number of revolutions of the engine to drive the motor when the voltage is higher than a predetermined voltage. It is an object of the present invention to provide a gear shift timing notification device of a manual transmission vehicle that can automatically inform a driver of a gear shift timing by vibrating the diaphragm.

The present invention for achieving the above object is a tachometer indicating the number of revolutions of the engine per minute, and a voltage discriminator for determining whether or not a predetermined voltage or more by detecting a current according to the number of revolutions of the engine from the tachometer, When the voltage determined by the voltage determination unit is a predetermined voltage or more, characterized in that the motor is driven, and the vibration plate is vibrated by the drive of the motor to inform the driver of the gear shift time.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The shift timing notification device of a manual shift vehicle according to the present invention includes a tachometer (1) indicating the number of revolutions of the engine per minute, as shown in FIG. A voltage discriminating unit (2) which detects a current according to the rotation speed of the engine from the tachometer (1) and determines whether or not a predetermined voltage or more is present; A motor 3 driven when the voltage determined by the voltage discriminating unit 2 is equal to or higher than a predetermined voltage; It is composed of a diaphragm (4) is vibrated by the drive of the motor (3) to inform the driver that the gear shift time.

In the figure, reference numeral 5 denotes a battery for supplying power to each electric device of the vehicle, and 10 denotes a gear shift lever for shifting gears in a manual transmission.

Referring to the operation and effect of the present invention configured as described above in detail.

When the driver starts the engine to drive the car, as the engine is rotated, the instructions of the tachometer 1 of the instrument panel are moved to indicate the engine speed.

On the other hand, as the rotation speed of the engine shown in the tachometer 1 gradually increases, the current I flowing gradually increases and is applied to the diode D of the voltage discriminator 2.

When the current applied to the diode D of the voltage discriminating unit 2 reaches the operating voltage of the diode D set at the proper rotational speed RPM, the diode D is turned on to relay RY. By driving the relay RY, the power supply of the battery 5 is supplied to the motor 3 installed in the gear shift lever 10 through the contact of the relay RY, The drive vibrates the diaphragm 4.

Here, the vibration is transmitted through the gear shift lever 10 to induce the driver to know that the gear shift time.

At this time, when the driver recognizes that the gear shift time is shifted by the progress transmitted through the gear shift lever 10 as described above, and the gear is shifted, the engine speed (RPM) shown in the tachometer 1 is lowered. As the rotation speed of the engine shown in the tachometer 1 decreases, the current I also decreases so that the diode D of the voltage discriminating unit 2 is turned off to turn off the relay RY and the relay RY. Since the power of the battery 5 is not supplied to the motor 3 installed in the gear shift lever 10 by the turn-off operation of the motor, the motor 3 is turned off to vibrate the vibration plate 4. Stop it.

Therefore, the driver repeatedly performs the above operation for every gear shifting period while driving by using a vehicle, thereby selecting an appropriate shifting period.

As described in detail above, the present invention, after installing the diaphragm in the gear shift lever of the manual transmission vehicle senses the voltage according to the number of revolutions of the engine and can vibrate the diaphragm by the drive of the motor when a certain voltage or more, the driver By automatically notifying the gear shift time to maintain a smooth running, thereby reducing fuel consumption, thereby improving the efficiency of driving the car.
