    Coupling Structure of Gear Shifting Rod
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting of a gear shift rod, wherein the gear shift lever is shifted according to the selection of a lever for gear shift and the gear is shifted by engaging the gear. It relates to a coupling structure of the gear transmission rod to facilitate the connection work according to the mounting of the.
    In general, gear shifting combines a plurality of gears having a plurality of gear ratios, and the rotational force shifted according to the engagement of the gears is transmitted to the axle of the wheel for driving so that the propulsion of the vehicle is performed. The car is selected according to the condition of the road surface to make the car run.
    At this time, the transmission for changing the rotational speed of the engine is connected to the drive shaft that is rotated in accordance with the operation of the engine so that the driving force with the rotational speed is transmitted to the axle for the propulsion of the vehicle.
    In addition, the gear is shifted by gear shifting rods engaged with gear shift levers according to the selection of the gear shift lever, so that the shift is made. The gear shift rod which transmits the action force according to the gear shift with the corresponding gear of the transmission is in the driver's seat. In accordance with the operation of the gear shift lever is provided with a predetermined length for transmitting the action force to the transmission to be shifted in the longitudinal direction so that the transmission of the transmission is made.
    On the other hand, the length of the gear shifting rod is determined according to the type of the vehicle, that is, the distance between the gear shifting lever located in the driver's seat and the transmission, and when the length is relatively short, such as a small car, a single gear shifting rod is used. If the length is long, such as a truck or a bus, a plurality of gear shift rods are extended to transmit the action force of the gear shift lever to the transmission.
    As shown in FIG. 1, the gear shifting rod having a long length, such as a bus or a van, is bent and formed with an insertion portion 112 for extending and inserting an end portion of the gear shifting rod 100 as shown in FIG. 1. The piercing coupling piece 116 is inserted into both sides of the gear transmission rod 100 for connecting to both sides of the bent extension band 110 so as to be spaced apart from each other by a predetermined distance and one side of the extension band 110 After forming the coupling hole 120 penetrating through the gear shifting rod 100 inserted into the inner side of the gear shift rod 100 inserted into the extension band 110 by inserting the coupling pin 122 and Rotation was prevented.
    However, the gear shifting rod coupled in the longitudinal direction is moved in the longitudinal direction according to the selection of the gear shift lever, and the gear of the transmission is selected so that the coupling band and the gear shifting rod are coupled by a tension force pulled in the longitudinal direction. There is a play in the coupling pin and the coupling hole, in particular, the flow of the gear shift rod is generated by the space portion spaced by a predetermined distance for the coupling and the movement distance of the gear shift lever for moving the gear shift rod is increased accordingly. At the same time, it was suggested that the gear shifting is not easy due to the delay caused by the decrease in the response of the gear shift caused by the operation of the gear shift lever.
    Therefore, the present invention is to solve the above problems, to prevent the occurrence of play due to the operation of the gear shifting rod is moved in the longitudinal direction by engaging the gear shifting rod connecting the gear shift lever and the transmission. Responsiveness according to the selection of the gear shift lever can be made quickly and accurately, so that the gear shift can be made quickly.At the same time, the gear shift lever prevents flow due to play and improves the maneuverability according to the gear shift, thereby improving the productability. It is an object of the present invention to provide a coupling structure of a rod.
    In order to achieve the above object, the present invention combines the universal joint for connection to both ends of the gear shifting rod of a predetermined length, respectively, and one of the universal joint for coupling the screw of the coupling portion is coupled to the support rod The screw coupling hole penetrates in the longitudinal direction of the gear shifting rod, and a screw shaft of a predetermined length is screwed to the screw coupling hole, and the screw can be rotated in all directions to the coupling portion screwed to the screw coupling hole of the universal joint. A gear shift coupled to the universal joint by hinge-engagement of the lifting rod to be coupled and the lifting rod inserted into the lifting rod to be lifted in the longitudinal direction thereof so as to rotate in a longitudinal direction of the gear shifting rod at a predetermined position of the body frame. The rod is supported by its longitudinally movable structure. This document intended purpose is achieved.
    The coupling portion coupled to the support rod of the present invention as described above is rotatable and coupled to a ball joint using spherical bearings so as to rotate in all directions and prevent flow.
