Description

[Detailed Description of the Invention] This invention relates to a roll stopper control device that drives a roll stopper that prevents rolling of the engine for a certain period of time after a clutch is engaged.

The engine installed in a car vibrates along with the vibrations of the car body, but especially after a gear change and after the clutch is engaged, the engine accelerates or decelerates. Large rolling was likely to occur, which was unfavorable in terms of performance. This kind of excessive rolling needs to be suppressed by strongly regulating engine movement, but if engine movement is strongly regulated all the time, engine vibrations will be transmitted to the vehicle body even when the engine is idling, causing harm to the occupants. There are drawbacks that can cause discomfort.

This idea was made in view of the above points,
The object of the present invention is to provide a roll stopper control device that prevents engine rolling by driving a roll stopper that prevents engine rolling for a certain period of time after a clutch is engaged.

An embodiment of this invention will be described below with reference to the drawings. Figure 1: The location where the engine is loaded in a FF vehicle will be explained. In Figure 1, 1
1 is an engine, and 12 is a transmission installed on the side of the engine 11. It is placed on the vehicle body 14 by the transmission mount 13 described above. Furthermore, the engine 11 is mounted on the vehicle body 14 by a left mount 15. Therefore, the engine 11 and the transmission 12 installed on the side thereof are connected to the vehicle body 1 by the transmission mount 13 and the left mount 15.
4. Further, a front roll stopper 16 is provided on the front of the engine 11,
A rear roll stopper 17 is provided on the rear surface. The front roll stopper 16 and the rear roll stopper 17 have a damper function to alleviate the rolling motion of the engine 11, and the performance of the damper function can be electrically controlled. FIG. 2 is a side view showing the positional relationship between the front roll stopper 16 and the rear roll stopper 17.

Next, using Fig. 3, set the front roll stopper 1.
6 and the basic principles of the rear roll stopper 17 will be explained. In FIG. 3, chambers A and B formed in casings 3 and 4 made of an elastic material such as rubber are each filled with oil, and a separation member 21 is provided between chambers A and B. There is. This separation member 21 has two through holes, one of which is called a first orifice 22 and the other a second orifice. Here, the inner diameter of the first orifice 22 is formed to be considerably larger than that of the second orifice 23. A rotary valve 24 is provided in the first orifice 22, and the rotary valve 24 is operated by a solenoid valve (not shown).
4 is rotated by 90 degrees to control opening and closing of the first orifice 22. By the way, the above casings 3 and 4
are integrally connected by a connecting member 5, and a bracket 6 connected to the engine 11 is attached to this connecting member 5. On the other hand, a bracket 7 fixed to the vehicle body is connected to one end of the separation member 21. Therefore, engine 11
The connecting member 5 moves in the direction of arrow D due to the rolling movement, etc.
When it vibrates in the direction, this vibration causes the orifice 22,
23, and is transmitted to the separation member 21 as minute vibrations in the direction of arrow C. In this case, when the rotary valve 24 is rotated to close the first orifice 22, the oil between the chambers A and B will flow only through the second orifice 23. As the amount of oil passing becomes smaller, the pressure difference between chambers A and B becomes larger (state of large damping force), and the amount of engine vibration transmitted to the vehicle body increases, but the rolling motion of the engine 11 can be effectively suppressed. Can be done. On the other hand, when the first orifice 22 is opened due to the rotation of the rotary valve 24, the first orifice 22
Since oil flows between chamber A and chamber B through the second orifice 23, the amount of oil passing between chamber A and chamber B increases, and the pressure difference between chambers A and B becomes small. (state where the damping force is small) The function of preventing engine rolling is reduced, but the amount of engine vibration transmitted to the vehicle body is reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A roll stopper control device according to an embodiment of the invention will be described below with reference to the drawings. In FIG. 4, 31 is a clutch connection switch that is closed when the clutch is connected. One end of the clutch connection switch 31 is grounded, and a voltage V1 (for example, V8) is applied to the other end via a resistor R1. The connection point between the resistor R1 and the clutch connection switch 31 is connected to a timer circuit 33 via an inverter 32. This timer circuit 33 outputs an H level for a certain period of time after receiving an H level signal. Further, the output of the timer circuit 33 is input to a solenoid drive circuit 34, which is connected to the first solenoid drive circuit 34.
A drive signal a is output to the front roll stopper 16 shown in the figure, and a drive signal b is output to the rear roll stopper 17. That is, when an H level signal is input to the solenoid drive circuit 34, the drive signals a and b become active.

Next, the operation of this device configured as described above will be explained. When the clutch of the vehicle is not engaged, the clutch connection switch 31 is open. Therefore, the voltage V1, that is, the H level signal is input to the inverter 32. Therefore, the input of the timer circuit 33 becomes L level. Therefore, the output of the timer circuit 33 becomes L level, and an L level signal is input to the solenoid drive circuit 34. Therefore, the drive signals a and b output from the solenoid drive circuit 34 do not become active. Therefore, when the clutch is not engaged, the front roll stopper 16 and the rear roll stopper 1
7 is the first orifice 22 and the second orifice 23
is open, and the damper function against rolling of the engine 11 becomes soft.
Transmission of engine vibration to the vehicle body side is effectively prevented.

On the other hand, when the clutch is connected after the gear change, the clutch connection switch 31 is closed. Therefore, the ground potential (L level) is supplied to the inverter 32. Therefore, an H level signal is input to the timer circuit 33. As a result, the timer circuit 33
The output of is in the H level state for a certain period of time. Therefore, the drive signals a and b output from the solenoid drive circuit 34 remain active for a certain period of time.

That is, by performing a gear change, engaging the clutch, and then operating the roll stopper and closing the first orifice 22, the damper function against rolling of the engine is worked hard to effectively prevent excessive rolling of the engine.

As detailed above, according to this invention, a roll stopper that prevents the engine from rolling for a certain period of time after a gear change is performed and the clutch is engaged is activated, and the damper function for the engine is made hard, so that people with manual transmissions can change gears. This can effectively prevent excessive rolling of the engine, which sometimes occurs.
