Abstract

The purpose of the present invention is that the semi-automatic clutch device of the manual transmission does not interfere with the operation even if one of the manual and semi-automatic clutches is broken, and both manual and semi-automatic clutches can be conveniently used for each condition. This is to focus on semi-automatic clutch using release cylinder with dual structure of 2 and 22

Description

Twin clutch release cylinder

Semi-automatic clutches have been developed due to frequent gear shifting of manual transmission vehicles, which lead to fatigue of the driver. In the past, there was a method of simply connecting cables to the clutch pedals and winding them around with a motor to cut off and connect the power. Many semi-automatic clutches have been registered for patents and utility models, and there are many registrations that are almost impossible to mount on the actual vehicles that have already been shipped. The semi-automatic clutch in the domestic market can be assembled in the current domestic market. As shown in Fig. 6, between the clutch master cylinder and the release cylinder, a cylinder 21, which is structurally identical to the clutch master, is installed between the clutch master cylinder and the release cylinder, and receives various input signals. Hydraulic actuating cylinder 21 with reduction motor It can be said that this week

However, weaning pressure semi-automatic clutch has three hydraulic lines (cylinders 1, 21, 2) connected in series, as shown in Fig. 6, so that when one of them fails (oil shortage, internal blockage of cylinder 21). This can cause the clutch to be inoperable and a small flow rate can occur between the points, resulting in a change in play in manual and semi-automatic operation. The disadvantage is that no action can be taken

Therefore, in order to achieve the purpose of this paper, as shown in Fig. 2, the secondary release cylinder 22, which is operated by a semi-automatic clutch line, separates from the existing primary release cylinder 2. As shown in Fig. 4, the existing primary clutch release cylinder is installed. A secondary clutch release cylinder 22 actuated by a semi-automatic clutch line between 2 and the clutch fork is installed and the application example is shown in Fig. 7. As shown in Fig. 7, the conventional clutch hydraulic lines are 1 and 2 and the semi-automatic clutch hydraulic lines are 21 and 22. Since the oil of the clutch hydraulic lines of these two lines is not connected at all internally, there is no change in the flow rate of each other.

In this regard, I would like to suggest another type of semi-automatic clutch using the advantages of the double-release cylinder.

(Configuration)

The composition of this paper is as follows.

First, in order to obtain the action proposed by the present design between the existing primary release cylinder 2 and the clutch fork 3, as shown in Fig. 8, the position of the bolt 113 as shown in Fig. 12 is ON to OFF or OFF to ON. Switch 100, which is operated with the adjustment nut 110, is attached to the secondary clutch release cylinder 22 body as shown in Fig. 8, and the secondary clutch release cylinder 22 with the bracket 16 actuating the switch 100 is installed.

Next, as shown in Fig. 10, the IN line of the suction solenoid valve 72 is connected to the high pressure hose 53 connected to the hydraulic pump, the T line is connected to the OUT line, and the T side is connected to the high pressure hose 52 connected to the secondary release cylinder 22. One end is to be piped to the other side of T, which is connected between 70 and 71 of the exhaust solenoid valve IN line.

Adjusting valves 80 and 81 are installed in the OUT line of the exhaust solenoid valves 70 and 71, and the regulating valve 80 is adjusted in a small amount in a large amount (the regulating valve is adjusted at the optimum state because the return speed of the clutch fork). The OUT line of valves 80 and 81 are all connected to the exhaust hose 51, which is connected to the return tank of the hydraulic pump.

Finally, as shown in Fig. 11, the switch contact is turned OFF when the first gear is inserted, and the switch contact turns OFF when the pedal is stepped on. To install the gear lever switch 160 which is turned ON when the switch attached to the gear lever is turned on.When the clutch pedal is pressed, the gear lever switch 160 is grounded and the exhaust solenoid valve 71 is grounded to release the hydraulic pressure. Install the switch 150 and install the 5P relay 120 with the contact points operated in accordance with the ON / OFF of the gear lever switch 160.The primary clutch position detection switch 121 and the half clutch whose clutch fork is changed from the half clutch (clipping) state to the OFF position. Install the second clutch fork position detection switch 122 that passes through the state and becomes ON when the connecting shock absorption section of the clutch power is passed.

(Action)

When the gear lever switch 160 is pressed in Fig. 11, the power supply of the 5P switching relay 120 shuts off the large exhaust solenoid valve 70 and the small exhaust solenoid valve 71 and applies the suction solenoid valve 72 so that the hydraulic pressure generated from the pump passes through the valve 72 and the high pressure hose of FIG. The secondary release cylinder 22 connected to 52 is applied to press the piston 11 in the secondary release cylinder 22 as shown in FIG. 4 to actuate the clutch fork 3 to cut off the power.The driver shifts the gear to the first stage and the gear lever switch When the 160 is released, the power of the 5P switching relay 120 shuts off the suction solenoid valve 72 and is applied to the bulk 70 and the small exhaust solenoid valve 71. The ground of the bulk exhaust solenoid valve 70 is applied to the fork position detection switches 121 and 122. 121 operates at the exhaust speed of the adjustment valve 80 until the half clutch (clipping) state of the fork is preset, and grounding is turned on and then turned off. Grounding of the value detection switch 122 is not the ground there is a one-stage switch 130 is OFF, which operates a large amount of the exhaust solenoid valve 70 operates only to half-clutch (clipping) conditions

Another small exhaust solenoid valve 71 is grounded because the 1-stage switch 131 is OFF and the Excel switch 140 is OFF. Therefore, the small exhaust solenoid valve 71 does not operate.In this case, the vehicle does not turn off when the driver presses the brake. When the driver releases the pedal, the car will move forward slowly. At this time, if the driver presses the accelerator pedal, the accelerator switch 140 is turned on.The small amount of exhaust solenoid valve 71 becomes the ground, and the clutch power is fully connected as much as the regulated speed of the control valve 81.

Then, when the driver presses the gear lever switch 160 and shifts the gear to the second stage and releases the lever switch 160, the small exhaust solenoid valve 71 continues to operate because the first stage switch 131 is turned on, and at the same time, the large exhaust solenoid valve 70 is the clutch position sensing switch. The clutch position detection switch 122 is turned on and grounded to the 1st stage switch 130 after the point of operation by 121 to the half clutch section and absorbing the clutch connection shock by the small exhaust solenoid valve 71. All clutch connections up to 5 stages are the same principle, so the clutch is connected quickly and the power absorption is made by connecting the force naturally.

The operating sections of all these exhaust valves and various switches are briefly summarized in the table of FIG.

As described above, when the driver accidentally presses the clutch pedal while using the semi-automatic clutch, the gear switch 160 is turned off by the clutch switch 150, the exhaust solenoid valve 71 is grounded, the residual pressure is released, and the immediate manual changeover is performed. do

As described above, the present invention installs a semi-automatic clutch line (FIG. 9) using a clutch release cylinder having another dual structure separately from the existing clutch line (FIG. 5), even if either manual or automatic failure occurs. It is possible to convert between manual and automatic, easy to make mutual security relationship, and it is easy to operate even if it is not complicated electronic way, so it is possible to lower the cost, to make the structure simple, and to standardize parts, so that mass production is possible. The installation is not so difficult that it has the advantage of easier access to the end consumer.
