Description

Description: TECHNICAL FIELD The present invention relates to a remote control device for a transmission in a vehicle, and in particular, an electric signal generating element and a manually applied cylinder device are separated from a change lever portion, and these are connected by a cable. The present invention relates to a remote control device with a downsized change lever portion installed in a driver's seat.

2. Description of the Related Art Conventionally, various automatic transmissions in which a manual transmission is operated by an operating device that uses air or electricity as a power source, and various command units including a change lever for remotely operating the operating device have been proposed. However, in the conventional command unit, the change lever section has an integral signal section including an electric element such as a micro switch, a magnet, and a Hall element that generates an electric signal and an air cylinder device that generates a reaction force of various hand applications. It was built in. For this reason, the change lever portion becomes large in size, and the change lever portion is installed on the left side of the driver's seat or the like, so that there is a drawback that it becomes an obstacle when getting on and off, especially in the case of a bus. In addition, there is a problem that the design around the driver's seat is limited due to the large size of the change lever.

Further, Japanese Utility Model Laid-Open No. 57-199333 discloses a remote control mechanism for a transmission for an automobile. However, in the conventional example, the change lever portion is composed only of elements for mechanically guiding or supporting the change lever portion. , This is one in which the shift shaft and select shaft of the transmission are directly operated through the cable by the manual operation force of the change lever, and like the present invention, it is automatically operated by using electricity or fluid pressure. This method does not attempt to reduce the operating force by shifting the transmission, but with this method, it is good if the distance between the change lever and the transmission is short, but like the rear engine bus, from the front of the vehicle. When operating the rear transmission, the operating force becomes very heavy, making it difficult to operate.

Further, Japanese Utility Model Publication No. 56-25072 discloses a remote control device. Although the conventional example discloses a technique of operating electrical elements with a cable, it does operate a simple switch with a cable. However, it does not disclose the idea of connecting the gear change lever of the automobile transmission and the signal portion with a cable.

Further, Japanese Utility Model Laid-Open No. 57-42266 discloses a valve body structure in a double-acting valve. In the conventional example, the valve generating a reaction force is located away from the change lever, but is directly connected by a rod. However, it does not disclose the technique of connecting the operation lever and the power booster for operating the transmission with a cable, and is a completely different invention from the present invention.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the prior art, and an object of the present invention is to automatically change gears of a transmission by using an operating device. In the device that is remotely operated in the driver's seat, an electric element for generating an electric signal from a change lever portion of a command unit and a signal portion including a cylinder device for generating reaction force of various hand applications are separated, By connecting these with a cable such as a push-pull cable, the change lever section can be made smaller,
The aim is to widen the space around the driver's seat, improve passenger entry and exit, and increase design flexibility. Another purpose is
The signal part is to be able to be stored inside the dashboard, and by doing so, it is not necessary to install the piping for the air cylinder etc. in a place that is easily visible around the driver's seat, and the appearance around the driver's seat can be improved. It is to improve.

The signal unit 20 is integrally provided with a cylinder device 18 for giving a response to the change lever 4 during a shift operation and a cylinder device 19 for giving a response to the change lever 4 during a select operation. There is. A shift position detector 30 is slidably accommodated in the cylinder device 19, and one end of a push-pull cable 21 is connected by a pin 31 to one end 30a of the detector. Further, a pair of cylinder chambers 1 is provided at both upper and lower ends of the cylinder device 18.
8a and 18b are formed respectively, and a pair of hand application plungers 32 and 33 are slidably accommodated in the cylinder chamber. The tip 32a of the plunger 32 abuts on the upper surface of the detection body 30 and the plunger 33 The tip 33a is the detection body 30

A select position detector 34 is slidably accommodated in the cylinder 19, and one end of the push-pull cable 22 is connected to one end 34a of the select position detector 34 by a pin 35. A plunger 38 whose flange portion 38a is pressed downward by a coil spring 36 is in contact with the upper surface of the detection body 34, and always pushes the detection body 34 downward. On the lower surface of the detection body 34, the flange 40a of the plunger 40 is pressed upward by the coil spring 39.
Are in contact with each other, and the detection body 34 is always urged upward. The detector 34 is composed of a pair of coil springs 36, 3
When the change lever 4 is not selected in either direction by the pressing force of 9, the change lever 4 is configured to stand still at the position shown in FIG. In FIGS. 7 and 8, the magnet 13 is embedded in the side surface of the detection body 30, and the Hall element 15 is fixed to the inner surface of the cylinder device 18. The magnet 14 is embedded in the side surface of the detection body 34, and the Hall element 16 is fixed to the inner surface of the cylinder device 19.

Operation The present invention is configured as described above, and its operation will be described below. As shown in FIG. 1, the signal unit 20 is stored inside the dashboard 23, and only the change lever unit 3 is installed in the driver's seat 2. A push-pull cable 21 is provided between the change lever portion 3 and the signal portion 20,
It is connected by 22. Therefore, the change lever section 3 and the push-pull cable 2 are installed around the driver's seat 2.
Since the change lever portion 3 is only 1 and 22 and the change lever portion 3 is smaller than that of the conventional signal portion by the signal portion 20, the space around the driver's seat 2 becomes wider, the degree of freedom in design is increased, and the aesthetic appearance around the driver's seat is increased. Also improves, and the getting on and off property is also improved.

Next, the shift / select operation of the remote control device 1 for a transmission according to the present invention will be described. First, when the change lever 4 is swung as shown by arrows A and B in FIG. Swings around the spherical portion 4a, and the intermediate spherical portion 4b swings the guide plate 8 left and right. In this case, the select plate 6 is completely stationary because the groove 6a allows the guide plate 8 to move. As the shift plate 5 moves, the push-pull cable 21 reciprocates, which causes the detector 30 in the cylinder device 8 to reciprocate up and down. In this case, air is supplied from the air port 28c to the hollow portion 18a of the cylinder device, and a pressure applied by hand is applied. And the air port 18 is provided in the hollow portion 18b.
Similarly, air is supplied from d, and pressure applied by hand is also applied to the hollow portion. Therefore, when the push-pull cable 21 moves the detector 30 upward, for example, the air pressure in the hollow portion 18a causes the plunger 32 to move.
Is pressed downward, the change lever 4 is given an appropriate shift action. When the displacement amount of the change lever exceeds a certain value, the air port 28 is automatically
Air is exhausted from c and the reaction force of this hand application disappears.
In this way, at the initial stage of the shift operation of the change lever 4, a proper response is obtained by the air pressure, and when the shift operation is completed, it is known that the operating force becomes small and the shift operation is completed. This also applies to the case where the detection body 30 moves downward in FIG. In this case, when the detection body 30 moves upward, the magnet 13 faces the Hall element 15 in FIG. 7, so that an electric signal for the completion of the shift operation is generated. The same applies when the detection body 30 moves downward.

Next, as shown in FIG. 4, when the change lever 4 is selected as indicated by arrows C and D, the guide plate 8 reciprocates in the same direction, and the select plate 6 reciprocates in the same direction. In this case, the shift plate 5 is stationary because it allows the movement of the guide plate 8 by means of its groove 5a. When the select plate 6 reciprocates, the push-pull cable 22 reciprocates, and as a result, the detection body 34 reciprocates vertically. Then, for example, when the detection body 34 tries to move upward, the plunger 38 pushes the detection body downward due to the pressing force of the coil spring 36, and the change lever 4 is given a selection response. When the detection body 34 moves downward, the plunger 40 pressed by the coil spring 39 similarly provides a response for selection.

As described above, according to the present invention, even if the signal portion 20 is separated from the change lever portion 3, since they are mechanically connected by the push-pull cables 21 and 22, they are integrated as a conventional example. The same operation as that of the remote control device (not shown) of the transmission can be performed.

EFFECTS Since the present invention is configured and operates as described above, the gear shift operation of the transmission is automatically performed using the operating device, and the operating device is remotely operated in the driver's seat. In this case, the signal unit, which consists of an electric element that generates an electric signal from the change lever section of the command unit and a cylinder device that generates a reaction force for various hand applications, is separated, and these are connected with a cable such as a push-pull cable. Therefore, the change lever portion can be downsized, the space around the driver's seat can be widened, and there is an effect that the getting on / off property can be improved and the degree of freedom in design can be increased. In addition, the signal part can be stored inside the dashboard, and as a result, it is not necessary to install the pipes for the air cylinder etc. around the driver's seat where the eyes are easily visible. The effect of improving aesthetics is obtained.
