Description

A support-device for shift-rod in vehicles

The present invention relates to a vehicle shift rod support apparatus, and more particularly, to continuously secure the correct mounting position of the shift rod, and to reduce friction between the shift rod and the roller during rotation of the shift rod by operation of the shift rod. A vehicle shift rod support device that is a minimized roller assembly.

In general, the driver of the vehicle performs the gear shift by operating the shift lever provided in the driver's seat, and the operation force transmitted by the shifting cable or the shifting rod that is moved according to the selection of the shift lever shifts the corresponding gear to perform the shifting act. Lose.

The shifting cable or shifting rod that transmits the operating force of the shifting lever can be selectively used according to the type of the vehicle and the condition of the vehicle. Many shifting rods are used in consideration of efficiency and assembly maintenance.

To this end, as shown in FIG. 1, the roller assembly 2 serving as the support device is mediated to the shifting rod 1 to secure a mounting position of the shifting rod 1 and to assist the operation of the shifting rod 1.

That is, in a large commercial vehicle such as a bus, when the shift rod 1 is simply connected and assembled only to the shift lever 3 and the transmission 4, the shift rod 1 may be sag due to its own weight, and there may be a risk of bending during operation. There is.

In addition, there is a risk of damage caused by vibration noise and interference of peripheral parts when driving the vehicle, and because the smooth shifting is not performed due to front, rear, left and right play, the transmission efficiency is lowered. The roller assembly (2) is mounted as a device for supporting the speed change rod (1) in a proper section of the.

Referring to this in more detail based on Figure 2, the conventional roller assembly assembly 2 is a cylindrical roller (5) mounted on the top and the shift rod seating surface is formed to form a lower and side of the shift rod The spool roller 6 to be supported is sandwiched between the plates 8 by a support shaft 7 in which grease injection holes are processed, and the covers are wrapped.

In addition, the grease injection nipple 10 is assembled to one side of each support shaft 7 so that when grease is injected, grease injected through the grease injection hole processed in the support shaft 7 is fed to each roller and support shaft 7. It is lubricated between.

However, such a roller assembly 2 has a problem that the friction caused by the line contact of the transmission rod 1 and the splitter 6 is excessive when the shifting rod 1 is operated in the select direction.

In more detail, the shift operation is performed by the shift operation force moving the shifting rod 1 in the front-rear direction and the select operation force moving in the rotational direction.

In addition, during movement in the shifting direction, grease lubrication is desired between each roller and the support shaft 7, and the loss of shift operation force is not large due to rolling friction between the shifting rod 1 and each roller.

On the other hand, when operating in the select direction, as shown in Fig. 2b, the sliding rod 1 and the cylindrical roller 5 generate sliding friction by point contact, and the spool roller 6 generates sliding friction due to linear contact. Friction loss is inevitable.

Here, the spool roller (6) is formed to have a shift rod seating surface for preventing the left and right shake of the shift rod (1), the role for preventing left and right shake in the spool roller (1) is excessively concentrated.

As a result, it is inevitable to increase the mounting size of the rollers in proportion to the outer diameter of the shifting rod 1, and it is inevitable to use rollers having different shapes due to the up and down dualization. There was play in the operation of the sect, resulting in a decrease in the transmission efficiency of vibration and noise generation.

In addition, it is difficult to compensate for the amount of wear when play occurs due to wear, and if the distance between the shaft supporting the roller and the assembling hole of the plate is not correct, the distance between the rollers is too narrow or far, so that the shift rod may be difficult to assemble or may have vibration. In the beginning, even if the center of the transmission rod was set correctly, it was difficult to readjust when the center shifted due to long-term use.

In addition, as the assembly of the upper and lower rollers is limited in assembly, only one-way mounting is possible, and the worker has to check the direction of the rollers when the upper and lower rollers are assembled by all means.

Accordingly, the present invention has been made to improve the above problems, it is an object of the present invention to provide a vehicle transmission rod support device that accurately supports the position of the transmission rod while minimizing wear.

Other objects, features, and operational advantages, including the purpose, working effects, and the like of the present invention will become more apparent from the description of the preferred embodiment.

For reference, the embodiments disclosed herein are only presented by selecting the most preferred examples to help those skilled in the art from the various possible examples, the technical spirit of the present invention is not necessarily limited or limited only by this embodiment, Various changes and modifications are possible within the scope without departing from the technical spirit of the present invention, as well as other equivalent embodiments will be found.

Exemplary drawings Figure 3 is an explanatory view showing a roller assembly according to the present invention, the present invention is the three cylindrical rollers 5 are conformally arranged so that the transmission rod 1 is supported by the point contact of the cylindrical roller (5) The vehicle shift rod support device installed between the support plates 20.

Here, the support plate 20 is interlocked with the cylindrical roller (5) and the other two cylindrical roller (5) mounted here by adjusting the separation distance between any one of the support plate 20, the transmission rod (1) and the cylindrical roller Adjacent support plates 20 are connected to each other so that the contact state of (5) is changed, and an adjustment clearance space (a) is formed between the support plate 20 and the cylindrical roller (5).

As described above, the present invention supports three points of the outer circumference of the shifting rod 1, thereby continuously securing the correct mounting position of the shifting rod 1 and shifting the rod by the operation of the shifting rod 1, in particular a select operation. A roller assembly is provided as a shift rod support device which minimizes the friction between the shift rod 1 and the roller during the rotation of (1).

The three-point support by the roller assembly according to the present invention minimizes friction by the cylindrical roller 5, which will be described in more detail in comparison with the conventional spool roller, and the conventional spool roller is supported side by side with the lower support of the shifting rod. It is formed so that the transmission rod can be seated to cover.

This caused excessive friction between the transmission rod and the spool roller during rotation of the transmission rod by the select operation, because the spool roller is responsible for the excessive action in the transmission rod support device.

That is, in the present invention, the result of dispersing such an excessive function of the conventional spool rollers into two cylindrical rollers 5 is such that the two cylindrical rollers 5 share the function of the spool rollers.

The outer circumference of the shifting rod 1 is supported by three conformal arrangements of the cylindrical rollers 5, thereby restraining the position of the shifting rod 1 on a plane, and comparing the rotation of the shifting rod 1 to the line contact. This is a slight friction with a sharp difference from the conventional friction.

The cylindrical rollers 5 are installed between the support plates 20 disposed at right angles, and are installed on the support shafts 7 in which grease injection holes are formed as in the prior art.

On the other hand, the friction of the cylindrical roller 5 due to the select operation is also small but inevitably generated.

The adjacent support plate 20 is connected for easy wear compensation when the cylindrical roller 5 is worn by friction, and an adjustment clearance space a is formed between the support plate 20 and the cylindrical roller 5. .

That is, when the assembly nut 22 is tightened in one of the support plates 20, the other support plates 20 adjacently connected to each other are moved about the cylindrical rollers 5 at each location, thereby the cylindrical rollers 5 ) Wear compensation is easy.

In addition, it is easy to secure the center position of the transmission rod (1) in the roller assembly.

As described above, according to the present invention, by supporting the cylindrical roller and the shifting rod by three points, the wear amount is reduced, thereby extending the life of the roller assembly as the shifting rod supporting device, and improving the shifting operation due to the reduction of frictional force. Compensation is possible.

In addition, vibration and noise are prevented by wear compensation of the roller, and the center line of the shift rod is maintained.

In addition, since the same cylindrical roller is used, the directionality is not necessary when assembling, so assembly is possible in any direction, and there is no need for the operator to confirm, which makes the work quick and easy, and prevents bad mounting, and unlike conventional spool rollers. Since the size of the roller can be minimized, the material cost is reduced, and as described above, the amount of wear can be easily compensated, thereby reducing the cost of repairing or replacing parts.
