Figure 2 is an exploded view showing the mounting structure of the vehicle's suspension knuckle according to an embodiment of the present invention, Figure 3 is a perspective view showing a vehicle's suspension knuckle according to an embodiment of the present invention, Figure 4 is a partially enlarged view illustrating a shock absorbing portion of a vehicle knuckle for suspension according to an embodiment of the present invention.

2 to 4, the vehicle knuckle 50 for suspension according to an embodiment of the present invention, the shock absorber 60 is connected to the shock absorber 60, the shock absorber 60, ) Includes a rotating portion 80 rotatably connected.

Thus, when the bracket 62 mounted on the lower end of the shock absorber 60 is fastened to the shock absorbing part 70 and the hinge part 80, the shock absorber 60 flows by a predetermined amount by the shock absorbing part 70. Since the shock absorber 60 is rotated around the rotating unit 80, the shock absorber 60 can perform a flow that approaches the vertical direction.

Here, the shock absorbing portion 70 is a buffer hole portion 74 to which the shock absorber 60 is connected, a fixing hole portion 72 having a buffer hole portion 74 provided inside, a buffer hole portion 74 and a fixing hole portion 72. An elastic member 76 interposed therebetween, and a space 78 formed in the elastic member 76.

Two fastening hole portions 64 are formed in the bracket 62 installed at the lower end of the shock absorber 60, and the fastening hole portion 64 disposed above the buffer hole portion 74 and the fastening member (not shown). The coupling hole 64 coupled to the lower portion is coupled to the rotating hole 84 of the hinge portion 80 to be described later by the coupling member.

Thus, when friction occurs between the cylinder constituting the shock absorber 60 and the piston arm, the shock absorbing hole 74 flows a predetermined amount, and the rotation hole 84 is rotated so that the shock absorber 60 rotates a predetermined amount in the vertical direction. This reduces friction between the cylinder and the piston arm.

The hinge portion 80 includes a rotation hole 84 to which the shock absorber 60 is connected, a hinge hole portion 82 having a rotation hole 84 inside, and a rotation hole 84 and a hinge hole 82. The rotating member 86 is interposed therebetween, and the rotating member 86 includes a bush that rotatably connects the rotating hole 84 to the hinge hole 82.

As a result, when the shock absorber 60 flows by the shock absorbing part 70, the shock absorber 60 rotates about the hinge part 70 by the bush because the rotating hole 84 is rotated inside the hinge hole 82. Will be made.

In addition, the rotating member 86 of the vehicle knuckle 50 for suspension according to another embodiment of the present invention includes a bearing, which is a rotary motion of the shock absorber 60 rotated about the hinge portion 80 This is to make this easier.

Looking at the operation of the knuckle for the suspension device of the vehicle according to an embodiment of the present invention configured as described above are as follows.

First, when the vehicle passes uneven terrain while driving the vehicle, the vehicle body flows in the vertical direction. At this time, the piston arm constituting the shock absorber 60 flows inside and outside the cylinder to reduce the vertical flow.

Here, since the vehicle body flows in the vertical direction, but the shock absorber 60 is installed to be inclined at a predetermined angle in the vertical direction, friction occurs between the piston arm and the cylinder when the piston arm slides inside and outside the cylinder. Reaction force is generated.

When reaction force is generated by the operation as described above, the elastic member 76 is compressed to one side while the buffer hole portion 74 flows a predetermined amount inside the fixing hole portion 72, and the rotating hole portion 84 is rotated by the rotating member 86. ) Rotates inside the hinge hole 82, the shock absorber 60 is rotated a predetermined amount about the hinge 70 in the vertical direction is made.

As a result, the friction generated at the inlet of the cylinder is reduced as the linear motion of the piston arm is changed to the vertical direction, thereby reducing the reaction force.

The configuration and operation as described above improves the riding comfort of the vehicle and improves the steering stability.

Reference numeral 52, which has not been described, is a rotating shaft to which the wheel of the vehicle is rotatably connected.
