Description

Shift-Cable Assembly of Manual Transmission for Automobile

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission cable assembly of a manual transmission vehicle, and more particularly, to a transmission cable assembly of a manual transmission vehicle in which a gasket is interposed between a boot and a guide pipe or a socket to double seal the boot.

The shifting cable of a manual transmission vehicle according to the prior art is provided between a shift lever provided near a driver's seat and operated according to a driver's will, and installed between a shift transmission and an engine's manual transmission for changing a rotational force and speed of the engine to a driving wheel. To the manual transmission.

Such a shift cable is divided into a select cable for transmitting a select operation force of the shift lever and a shift cable for transferring a shift operation force of the shift lever since the shift lever is operated in a select / shift direction during a shift operation. As shown in FIG. 1, the inner and outer cable 4 and the inner cable 4 which are connected to the shift lever and the manual transmission side change lever through the ball joint 2 and transmit the shift operation force are covered on the outside of the vehicle body. It consists of an outer cable 6 which is fixed and protects the inner cable 4.

The outer cable 6 is formed to be shorter than the inner cable 4, and both sockets 8 are installed at both ends of the outer cable 6 so that the inner cable 4 is movably inserted in the longitudinal direction. It is fixed to the body.

The inner cable 4 which is not covered by the outer cable 6 or the socket 8 is provided with a guide pipe 10 for guiding the linear movement of the inner cable 4. ) Is one end of the socket side is pressed into the inside of the socket (8), the boot 12 of the elastic material to prevent the foreign matter from entering between the guide pipe (10) and the socket (8).

However, the transmission cable assembly of the manual transmission vehicle according to the prior art, when the boot 12 is deformed or worn when assembling, there is a gap, foreign matter such as rust generated from the inner cable 4 exposed to the outside or moisture Penetrating into the interior of the boot 12 through the gap is not only the transmission operation force is not exactly transmitted, but the shift operation force is large, there is a problem that the wear is quickly become a factor of consumer dissatisfaction.

The present invention has been made to solve the above problems of the prior art, the transmission cable assembly of the manual transmission vehicle improved the structure of the boot so that the boot is deformed or worn so that foreign matter or moisture is not introduced to the inner cable side through the boot. The purpose is to provide.

The transmission cable assembly of the manual transmission vehicle according to the present invention for solving the above problems is installed between the transmission lever and the manual transmission and the inner cable for transmitting the operating force of the transmission lever to the manual transmission; A guide pipe which is covered on the outside of the inner cable to guide the linear movement of the inner cable; An outer cable covered on an outer side of the inner cable to allow movement of the inner cable; A socket installed between the outer cable and the guide pipe and fixed to the vehicle body; Covered between the socket and the guide pipe is configured to include a boot to prevent foreign matter from entering,

In particular, the boot is characterized in that the gasket for sealing the boot is in close contact with each other by the elastic force on the inner surface of the guide pipe and the socket.

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

The shifting cable assembly of the manual transmission vehicle according to the present invention is arranged to be movable in the longitudinal direction between the shift lever and the change lever of the manual transmission as shown in FIGS. 2 and 3 and to the change lever of the shift lever and the manual transmission. The inner cable 54 coupled to each other through the ball joint 52 to transfer the operating force of the shift lever to the manual transmission, and is covered on both outer sides of the inner cable 54 to move linearly of the inner cable 54. A guide pipe 56 for guiding the outer cable, an outer cable 58 covered on the outer side of the inner cable 54 between the guide pipe 56 so that the inner cable 54 can be moved, and the outer cable 58 A socket 60 installed outside the inner cable 54 between the guide pipe 56 and the guide pipe 56, and covered between the socket 60 and the guide pipe 56 to prevent foreign substances from entering. It is configured to include a boot (62).

In the above, since the outer diameter of the guide pipe 56 is smaller than that of the socket 60 and is pressed in the lengthwise direction of the socket 60, the boot 62 is a portion 62a compressed to the guide pipe. Its outer diameter and inner diameter are smaller than the portion 62b pressed into the socket, and the portion 62a pressed into the guide pipe is formed into a hose shape thicker than the portion 62b pressed into the socket. A stepped portion 62c is formed between the portion 62b that is pressed into the pipe and gradually widens toward the socket 60 between the portion 62b that is pressed into the socket.

Here, the plurality of corrugations 62d are formed in the stepped portion 62c of the boot so that the guide pipe 56 and the socket 60 can be pressed more strongly by forming a plurality of corrugations 62d in the longitudinal direction. It is possible to prevent the play between the 60).

In addition, the boot 62 is easily introduced foreign matter through the end of the guide pipe 56 side, the reinforcing rib 62e extending outwards over the entire circumference is added to the end of the guide pipe 56 side Since the gap between the guide pipe 56 and the guide pipe 56 may be more firmly pressed against the guide pipe 56.

In particular, the boot 62 is in close contact with the outer surface of the guide pipe 56 and the socket 60 by an elastic force on the inner surface so that foreign matter does not flow through the boot 62 even if it is deformed or worn during assembly. A pair of gaskets 63 which double seal the boot 62 are protruded.

The gasket 62f is formed in an empty ring shape so that the gasket 62f can be compressed around the guide pipe 56 or the socket 60 by an elastic force, and the outer surface attached to the inner surface of the boot 62 is It is formed wider in the axial direction than the inner surface in close contact with the outer circumferential surface of the guide pipe 56 or the socket (60).

The shift cable assembly of the manual transmission vehicle according to the present invention configured as described above has a pair of gaskets which are in close contact with the guide pipe and the socket, respectively, on the inner surface of the boot which is covered between the guide pipe and the socket, and has a relatively high sealing force. Since a reinforcing rib is added to the end of the lower guide pipe side boot, the guide pipe and the socket are double sealed to prevent foreign substances or moisture from penetrating into the inner cable side, thereby improving durability.

In addition, the transmission cable assembly of the manual transmission vehicle according to the present invention is formed between the guide pipe and the socket because a plurality of corrugations are formed in the longitudinal direction to increase the compressive force in the step portion of the boot corresponding to the portion where the guide pipe and the socket is connected. There is an advantage that can prevent the play.
