Description

Transmission cable support structure of vehicle manual transmission control mechanism

The present invention relates to a transmission cable support structure of a manual transmission control mechanism for a vehicle, and more particularly to a support structure of a cable for transmitting the operating force of the shift lever to the manual transmission.

In general, the transmission of the vehicle is to increase or decrease the rotational force of the engine in accordance with the change of the driving state of the vehicle between the input shaft connected to the engine via the clutch and the output shaft connected to the driving wheel.

As a kind of such a transmission for a vehicle, a gear type manual transmission is known widely to selectively drive one set of a plurality of sets of gear devices disposed between both shafts. In this type of manual transmission, the input shaft or the output shaft is usually used. A synchronous device is provided for smooth engagement of the gear spline and hub of the slidably fitted gear device and the sleeve.

Among these synchronous devices, two and three friction coupling units are used to increase the synchronous capacity, and so-called triple and triple synchronous coupling devices are usually provided with an inner ring, an outer ring, a double cone, and a synchronizer key. The double synchronous gearing system has an inner ring and an outer ring frictionally coupled to the double cone at two places from both sides in advance of the hub and sleeve engaging the gear spline, and the triple synchronous gearing device has two inner rings and gears as described above. One more frictional engagement portion between the boss portions of the is added so that the gear spline, the hub and the sleeve can be synchronously rotated.

Referring to the structure of a conventional manual transmission equipped with such a synchronous engagement device is as follows.

The input shaft connected to the engine and the output shaft connected to the differential are arranged in parallel, and a pair of 1st gear, 2nd gear, 3rd gear, 4th gear, and 5th gear are sequentially fitted to each axis. On the other hand, a reverse idle shaft is provided in parallel with the input shaft and the output shaft, one end of which is supported by the clutch housing, and the other end of which is supported by the transmission case. On the reverse idle shaft, a reverse idle gear interlocked with the shift lever is slidably fitted. A reverse drive gear that transmits power to the reverse idle gear is integrally formed on the input shaft, and a reverse driven gear that receives power from the reverse idle gear is integrally formed on the output shaft. That is, the reverse drive and the driven gear are located on the same line, and are engaged with each other by the reverse idle gear moved along the reverse idle axis, so as to transmit the reverse driving force.

Here, the forward gears to which the synchronous device is applied are helical gears with high strength and low engagement noise, whereas the reverse gears are spherical gears because they are engaged by selective sliding type rather than synchronous gears.

Between the above-mentioned gears, there are synchronous devices for synchronously rotating and transmitting the power of the input shaft to the gears of the speed stage selected by the shift lever, and among these synchronous devices, a device with a proper gear ratio is selected according to the speed of the vehicle. And an operation mechanism for engaging each gear of the selected speed stage is shown in perspective in FIG.

As shown, the lower end of the shift lever 1 is supported on the upper surface of the base plate 2 and the shift cable composed of a shift cable 31 and a select cable 32 at the lower end of the shift lever 1. 3) is connected. In particular, the transmission cable 3 is inserted into a hole formed in the lower surface of the base plate 2 extending downward from the upper surface of the base plate 2 and supported by the clip 4.

The support structure of the conventional transmission cable 3 is shown in more detail in FIG.

As shown, the transmission cable 3 is inserted into the hole of the base plate 2, and the clip 3 is fitted to the outer periphery between the transmission cable 3 and the base plate 2. Accordingly, the clip 3 is formed with a fixing groove 31 having a shape in which the inlet through which the outer circumference of the transmission cable 3 is fitted is narrower than the inner diameter thereof.

However, since the conventional transmission cable support structure is a system of supporting the outer circumference of the transmission cable 3 in the fixing groove 31 of the clip 4, the fixing groove 31 of the clip 4 due to poor tolerance. If the inlet is too narrow, it is difficult to insert the transmission cable (3), on the contrary, if too wide, it is easy to insert the transmission cable (3), but there is a problem that often occurs easily.

Therefore, the present invention is devised to solve the problems caused by the conventional transmission cable support structure, and is easy to install in place of the conventional clip and is fixed to the base plate semi-permanently, so that the transmission cable can be more reliably supported. An object of the present invention is to provide a transmission cable support structure of a vehicle manual transmission operating mechanism.

In order to achieve the above object, the present invention, as a structure for supporting the transmission cable to transfer the operating force of the shift lever to the manual transmission in the hole of the base plate;

A flat bracket having a hole into which the transmission cable is inserted is placed on a base plate, and a welding nut is installed at an outer lower portion of the base plate, and a bolt is fastened to the welding nut from an upper portion of the bracket. .

According to the above-described constitution of the present invention, the transmission cable is passed through the hole of the bracket, the bracket is placed on the base plate, and then the bolt is released from the welding nut by fastening the bolt to the welding nut to support the transmission cable. Until now, it is possible to support the shifting cable semi-permanently on the base plate.

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

As shown, in the present invention, as a means for supporting the shifting cable 3, the bracket 5 is used instead of the clip conventionally used.

That is, the bracket 5 has a flat plate shape, a hole through which the transmission cable 3 passes, and several bolt holes are formed on the outside thereof. Meanwhile, the welding nut 7 is welded to the lower portion of the base plate 2 where the bracket 5 is placed on the upper portion, that is, the position corresponding to the bolt hole position.

It is comprised as mentioned above, and the transmission cable 3 is inserted in the hole of the bracket 5, and the bracket 5 is settled on the base plate 2 here. Then, the bolt 6 is fastened to the welding nut 7 to fix the bracket 5 to the base plate 2.
