    Shock absorber of car
    The present invention relates to a shock absorber of a motor vehicle, and more particularly, to a shock absorber of a vehicle capable of preventing excessive movement of the vehicle body by appropriately absorbing it when vibration occurs when the vehicle is driven.
    In general, the shock absorber of a vehicle is a device that absorbs the natural vibration generated by the shock received by the spring while driving the vehicle to quickly attenuate the vibration to improve ride comfort. The shock absorber acts to change the up and down kinetic energy into heat, and there are solid friction type and hydraulic type according to the method, and usually hydraulic type is used.
    Figure 1 shows an example of a conventional car shock absorber, as shown in the upper and lower pistons (2, 3) at a predetermined interval in the axial direction inside the cylinder (1) formed of a cylindrical sealed container These are inserted into each of each of the upper and lower pistons (2, 3) is coupled to the coupling shaft (S) connected to the other portion and between the upper piston (2) and the lower piston (3) coil spring ( C) is inserted. Oil (O) is filled in the cylinder (1), and a plurality of oil passages (2a, 3a) are formed in the upper and lower pistons (2, 3).
    As described above, when the vehicle travels on an unpaved road or the like on an uneven road, and vibration is generated, the oil passages 2a and 3a formed in the piston 2 and 3 are filled with oil in the cylinder 1. Flowing through and receiving the elastic force of the coil spring (C), the upper and lower pistons (2, 3) move to each other in the middle to adjust the height of the vehicle body due to vibration.
    However, the structure has a problem that when the vibration is severe during driving of the vehicle, the height of the upper and lower pistons (2, 3) is reduced too much to cause the vehicle floor to hit the ground, causing damage to the vehicle.
    Therefore, an object of the present invention is to provide a shock absorber of a vehicle that can properly absorb the vibration occurs when driving the vehicle and to prevent excessive movement of the vehicle body.

A plurality of flow path grooves 6a are formed in the lower portion of the first expansion pipe 6, and the oil flows into the first connection pipe 4 while being inserted into the first expansion pipe 6 and moved up and down. It is provided with a control ball (B) to adjust. The portion where the first connecting pipe 4 and the first expansion pipe 6 extend is formed to have a curved surface. It is preferable that four flow path grooves 6a are formed at equal intervals.

In this case, a predetermined interval is formed between the upper surface of the piston part 8b and the second expanding part 7. Supported.
    Hereinafter, the operation of the automobile shock absorber of the present invention will be described.
    First, when the vehicle is in a normal running with a small curvature of the road surface, the weak vibration is generated so that the upper and lower pistons 2 and 3 move to the middle of the cylinder 1 to absorb the vibration. At this time, while the upper and lower pistons (2, 3) move to the middle of the cylinder (1), the oil inside moves through the oil passages (2a, 3a), and some of the first and second connecting pipes (4, 5) Will go through. First, the process of moving the oil through the first connecting pipe (4), the control ball (B) in the first expansion pipe (6) is located in the lower portion by its own weight, the first through the flow path groove (6a) The oil is passed through the first connecting pipe (4) through the expansion pipe (6). In addition, the process of moving the oil through the second connecting pipe (5), first, since the adjustment member (8) is moved upward by the support of the coil spring (C '), the blocking pin portion (8c) is the second connecting pipe The oil flowing into the second expansion pipe 7 in the state of opening (5) passes through the second expansion pipe 7 through the oil groove 8a formed on the outer circumferential surface of the piston 8b to pass through the second connection pipe ( Through 5).
    On the other hand, when the vehicle is driving on a severe road curvature such as a dirt road, when the vehicle is impacted, the upper and lower pistons (2, 3) move to the middle of the cylinder (1) at a high speed accordingly. Willing to. In this case, the first and second connection pipes (4, 5) to try to move the oil quickly, in the case of the first connection pipe 4, the control ball (B) is moved upward along the first expansion pipe (6) The upper passage is blocked, thereby preventing the oil from moving to the first connecting pipe (4). On the other hand, in the case of the second connecting pipe (5) due to the momentary impact on the upper surface of the piston (8b) of the adjustment member 8, the oil is pressurized to move the adjustment member to the lower block pin is the second connection pipe ( 5) to block the flow of oil.
    In this case, the oil is moved through the oil passages (2a, 3a) and the first and second connecting pipes (4, 5) in the normal driving to absorb vibration, and when the sudden impact is applied, the oil is connected to the first and second connections. By preventing the oil from moving through the pipes 4 and 5, the oil travels less so that the shock absorber becomes harder to prevent the body from touching the ground.
    As described above, the automobile shock absorber according to the present invention is a cylinder of the oil-filled cylindrical hermetically sealed container, and an oil passage is formed therein, and a coupling shaft is coupled to one side to be coupled to each other at predetermined intervals inside the cylinder. The upper and lower pistons, the coil springs inserted between the upper and lower pistons to support the upper and lower pistons, and the space between the upper and lower pistons and the space formed between the upper piston back and the cylinder surface. A first connecting pipe formed on an outer surface of the cylinder, a second connecting pipe formed on an outer surface of the cylinder so as to communicate a space between the upper and lower pistons and a space formed between the lower piston rear surface and the cylinder surface; It comprises a first control means for controlling the flow of oil and the second control means installed in the second connecting pipe to control the flow of oil Small vibrations generated during normal driving of the vehicle are absorbed gently, and when driving on a severely curved road, the shock absorber is reduced in movement, thereby preventing the vehicle from touching the ground, thereby preventing damage to the vehicle.
