2 to 4, a shackle assembly according to an embodiment of the present invention includes a vehicle frame 100, a link 200, a leaf spring 300, and a shackle 400.

The vehicle frame 100 includes a bumper stopper 110 that absorbs impact on one side. Due to excessive movement of the vehicle, the bumper stopper 110 is elastically moved upward, downward, leftward, and rightward as will be described later, so that the bumper stopper 110 moves in a manner equivalent to excessive movement of the vehicle. Therefore, the stopper 110 is installed to prevent the leaf spring 300 from being strongly contacted with a part of the vehicle frame 100 to damage the vehicle frame 100.

The link 200 is connected to one end of the vehicle frame 100 on both sides.

One end of the leaf spring 300 is engaged with the link 200 and fixed to the vehicle frame 100. The leaf spring 300 may include an axle 310 for holding the elasticity and the center of gravity of the leaf spring 300 at a position corresponding to the stopper 110.

The shackle 400 is installed at one end of the link 200 and the leaf spring 300 and is rotated due to the elasticity of the leaf spring 300. One or a plurality of variable holes (401) are formed on one side of the shackle (400) so as to allow the position of the leaf spring (300) to be varied to prevent a deviation of the leaf spring (300)

Generally, the shank is installed according to the height of the leaf spring 300 in order to prevent a shaft deviation of the leaf spring 300 from occurring. However, in general, the angle of the shackle 400 is not adjusted to an angle that does not cause a deviation of the shaft, and it is difficult to use the shackle 400 according to the present invention because it does not fit with other types of vehicles. However, when the variable hole 401 of the present invention is installed in a vehicle of a different model, it is possible to change the position by taking the height of the leaf spring 300 into consideration in the variable hole 401, Therefore, it is possible to prevent the deviation of the axial load. For this purpose, the shackle 400 may include a first shackle 410 and a second shackle 420. The first shackle 410 may be connected to one side of the link 200. The second shackle 420 may be fixedly coupled to one side of the variable hole 401 and the leaf spring 300. In this case, the first shackle 410 and the second shackle 420 may include a fixing pin 430 for fixing the first shackle 410 and the second shackle 420 together. The fixing pin 430 may be fixed to any one of the variable holes 401. The fixing pin 430 may be selectively inserted in consideration of the axial deviation. And may include a coupling pin 440 for fixingly coupling the second shackle 420 and one side of the leaf spring 300. In addition, the shackle 400 may further include rubber rubber 450 on the shackle 400 to reduce an increase in the elasticity speed due to the leaf spring 300. The elasticity of the leaf spring 300 is increased so that when the shackle 400 hits the vehicle frame 100 at an increased speed, The shackle 400 may also be broken, cracked, or have a residual thickness. To prevent this, a rubber material 450 is provided. A load displacement diagram of the leaf spring 300 is shown when the rubber 450 is installed and when the rubber 450 is not installed.

Figure pat00001

The description of the above-mentioned graphs will be simplified.

In the conventional type, only the stopper 110 operates. This determines the load (blue solid line). In this type, the second shackle 420 is added, so that the stopper 110 and the rubber 450 act. As a result, the load is increased (red dotted line). The consideration of the field use condition due to the increase of the load and the improvement of the durability of the leaf spring 300 can be achieved.

The vehicle frame 100 includes a central shaft 120 fixedly coupled to one side of the axle 310 and one side of the vehicle frame 100 to prevent the leaf spring 300 from slanting, . ≪ / RTI > Here, the center shaft 120 may prevent upward, downward, leftward or rightward movement of the axle 310.

According to the shackle assembly of the present invention, when the one-side wheels installed on both the left and right sides of the vehicle operate up and down, the movement of the left and right wheels is made to be the same to reduce the tilting of the vehicle body to one side, So as to improve the ride comfort of the riding on boarding the vehicle and improve the steering characteristics of the driver who drives the vehicle.

In addition, it is possible to prevent the occurrence of a variation in the axial stiffness of the leaf spring 300, thereby providing an occupant or a driver with a sense of stability and preventing the premature wear of the tire.

Further, the elasticity of the leaf spring 300 can be prevented, and the leaf spring 300 can be prevented from being damaged and the vehicle frame 100 can be prevented from being damaged.
