Description

Power interrupter of manual type transmission mission using negative pressure of automobile engine

The present invention relates to a power interrupter of an automobile, and more particularly to a power interrupter of a manual type transmission mission using an engine negative pressure of an automobile.

In the automobile, there are two types of transmission missions for shifting the torque transmitted from the engine to the axle, a manual transmission using a gear and an automatic transmission using a hydraulic pressure.

In the case of a vehicle equipped with the manual type transmission mission, the driver easily feels fatigue because the vehicle repeatedly steps on the clutch and shifts gears when the vehicle is stopped. In addition, if you release the brake pedal after climbing on the uphill, the car has a problem in that a backward collision occurs.

In addition, in the case of the autotransmission, there is no problem as described above, but the driver tends to be helpless while driving and has a relatively high fuel consumption.

The present invention has been made to solve the above problems, it is possible to obtain the effect of the automatic transmission by using the manual type of transmission mission, the manual type transformer using the negative pressure of the automobile engine can reduce the fatigue of the driver when stalled Its purpose is to provide a power interrupter for the mission.

In order to achieve the above object, the present invention, the first cylinder is installed in the conduit connected to the master cylinder and the brake unit to control the supply of hydraulic pressure from the master cylinder to the brake unit, and the negative pressure generation of the first cylinder and the engine A first connecting pipe for connecting the part, a first valve provided in the first connecting pipe, a second cylinder connected to the clutch operation unit and operating a lever for controlling the clutch disc, the second cylinder and the engine. A second connecting pipe connecting the negative pressure generating unit, a second valve provided in the second connecting pipe, and a third connecting pipe connected by the second cylinder and the third connecting pipe to adjust the negative pressure supplied to the second cylinder. And a control means for controlling the cylinder and the first and second valves according to the driving state of the vehicle.

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

The power interruption device of the manual type transmission mission using the negative pressure of the automobile engine according to the present invention can be used as an autotransmission vehicle when stalled, an example of which is illustrated in FIG. 1.

As shown in the drawing, the first cylinder 20 is installed in a conduit connected to the master cylinder and the brake unit to intercept the supply of hydraulic pressure from the master cylinder to the brake unit 11, the first cylinder 20 and the engine. The first connecting pipe 12 for connecting the negative pressure generating portion 30 of the first, the first valve 13 installed in the first connecting pipe 12, and the clutch operating unit 14 is connected to the clutch disk A second cylinder (40) for operating the lever (15) for controlling the pressure, a second connecting pipe (16) for connecting the second cylinder (40) and the negative pressure generating portion (30) of the engine, and the second connection A third valve 17 installed in the pipe 16 and a third connected by the second cylinder 40 and the third connecting pipe 18 to adjust the negative pressure supplied to the second cylinder 40. And a control means 60 for controlling the cylinder 50 and the first and second valves 13 and 17 according to the driving state of the vehicle.

Hereinafter, the power interruption device configured as described above will be described in more detail for each component.

The first cylinder 20 is to interrupt the supply of the hydraulic pressure supplied from the master cylinder to the brake unit 11, the first cylinder housing 21 having a supply port and discharge port 21a supplied from the master cylinder, It is installed inside the first cylinder housing 21, and includes a first piston 22 elastically biased toward the outlet forming portion side to open and close the outlet 21a.

Preferably, the first and second valves 13 and 17 use a check valve or a three-way valve operated by an electrical signal.

The second cylinder 40 is connected by the negative pressure generating unit 30 and the second connecting pipe 16 of the engine, the second piston 41 is installed therein, the second piston 41 and The connected rod 42 is hingedly connected to the end of the lever 15 for operating the clutch disk.

Although not shown in the drawing, the control means further includes all switches for converting the manual type and the auto as described above.

Referring to the operation of the power control device of the manual transmission transmission using the negative pressure of the engine configured as described above are as follows.

When the vehicle is driven and put into the auto mode by operating the switch in the congestion section, the control means 60 reads the state in which the speed of the vehicle is 0, and when the state continues for a predetermined time (about 3 seconds), the first valve Activate (13). In this way, the negative pressure generated from the negative pressure generating unit 30 of the engine is supplied to the first cylinder 20 through the first connecting pipe to block the flow path supplied from the master cylinder side, and the inner cylinder of the first cylinder 20 Since the hydraulic pressure is supplied to the brake unit 11 through the outlet 21a, the vehicle does not retreat even when the brake pedal is not pressed.

When starting from this state, press the clutch, insert 1 short word, operate the mode switch, and remove the pressure from the clutch pedal. In this case, the control means detects the auto mode state, opens the first valve 17, sends the negative pressure of the engine to the second cylinder, and moves the piston to maintain the neutral clutch state. At this time, since the second cylinder 40 is connected by the third cylinder 50 and the third connection pipe, the pressure in the state is always maintained by the piston and the spring in the third cylinder 50. This state prevents the vehicle from being pushed back because the power transmission state is a neutral clutch and the vehicle is advanced when the accelerator pedal is pressed.

The mode switch is operated when the vehicle is stopped and a high-speed driving is desired. In this case, the first and second valves 13 and 17 are operated by the control means to discharge the negative pressure acting on the first and second cylinders, and the neutral clutch state by the second cylinder 40 is released.

The power interruption device of the manual transmission mission using the negative pressure of the automobile engine according to the present invention operated as described above can be stopped or advanced only by the brake pedal by maintaining the neutral clutch state without continuously shifting the gears when the vehicle is stopped. . Therefore, the fatigue of the operator's gear operation can be reduced.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and various modifications may be made by those skilled in the art within the technical scope of the present invention.
