Suspension for Vehicles {SUSPENSION OF VEHICLE}
The present invention relates to a vehicle suspension, and more particularly, to a vehicle suspension that can reduce the number of parts, simplify the manufacturing process, and significantly reduce the installation space.
In general, the suspension device is connected between the axle and the body frame to absorb vibrations or shocks transmitted from the road surface while driving to improve ride comfort and stability of the vehicle.
This suspension is connected to the wheel 122 to the knuckle arm 102, as shown in Figure 3, the lower control arm 104 connected to the frame 108 at the bottom of the knuckle arm 102 is rotated A shock absorber 110 and a coil spring capable of being mounted, mounted with an upper control arm 120 connected to the frame 108 on the upper side, and having a vibration damping effect between the lower control arm 104 and the frame 108. 106 is integrally installed in the vertical direction.
That is, the shock and vibration transmitted from the road surface are absorbed by the coil spring 106 through the lower control arm, and the free vibration of the coil spring 106 is absorbed by the shock absorber 110 to perform vibration damping.
However, since the suspension device made as described above is composed of a plurality of link connection structures, the number of parts thereof increases and the structure becomes complicated.
In addition, since the coil spring and shock absorber are assembled in a vertically upright state, the installation space becomes large, and there is a problem in design.
Therefore, the present invention has been made to solve the above problems, the object of the present invention is to deal with the conventional upper control arm and coil spring function as a single leaf spring to simplify the structure and reduce the number of parts for a vehicle It is to provide a suspension device.
Another object of the present invention is to provide a suspension device for a vehicle which can be easily installed with a shock absorber by eliminating coil springs and maximizing space efficiency.
1 is a side view of the suspension according to the present invention.
FIG. 2 is an enlarged perspective view of part A of FIG. 1.
3 is an enlarged perspective view of part B of FIG. 1.
Figure 4 is a side view of the suspension according to the prior art.
Explanation of symbols on the main parts of the drawings
2: Body frame 4: Cross members 8, 9: Left and right knuckle arms
12: leaf spring 18: fastening bracket 30, 32: shock absorber
In order to achieve the above object, the present invention is fixed to the upper body frame on both sides, the cross member is installed in the transverse direction of the vehicle body, knuckle arm connected to the left and right wheels respectively, and the lower end and the cross of the knuckle arm A lower control arm rotatably connected between the lower ends of the members, and a leaf spring fixed to the upper end of the cross member, and both ends rotatably fixed to the upper end of the left and right knuckle arms, respectively. Provided is a vehicle suspension.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 is a side view of a rear wheel suspension according to the present invention, a cross member 4 fixed to a vehicle body frame 2, a knuckle arm 8 connected to a wheel 6, and a knuckle arm 8; And a lower control arm 10 connected between the cross members 4 and a leaf spring 12 mounted between upper ends of the left and right knuckle arms 8 and 9.
The knuckle arms 8 and 9 are connected to the rear wheels left and right wheels 8 and 8, respectively, and the upper end of the knuckle arm 12 is rotatably fastened, and the lower end of the lower control arm 10 is provided. It is rotatably fastened.
The cross member 4 is installed in a direction perpendicular to the traveling direction of the vehicle, the upper ends of both ends are fixed to the frame 2, the central upper end of the leaf spring 12 is fixed, the lower both sides are respectively left The other end of the right lower control arm 10 is rotatably fastened.
The leaf spring 12 is formed in a plate shape having a predetermined elastic force, both ends are rotatably fastened to the upper side of the left and right knuckle arms 8, 9, respectively, the center side is fixed to the upper side of the cross member (4) do.
The leaf spring 12 is appropriate to use a steel plate having a certain elastic force, or to use a plate body of the FRP material.
Looking at the connection structure between the leaf spring 12 and the knuckle arms 8 and 9, as shown in FIG. The bushing 16 formed at the upper end of the knuckle arm 9 is fitted to the fastening bracket 18, and the fastening pin 20 is sandwiched therebetween. That is, since the bushing 9 of the knuckle arm is fitted to rotate on the fixing pin 20, the leaf spring 12 is rotatably fixed to the knuckle arm 9.
In addition, the structure in which the leaf spring 12 is fixed to the cross member 4 has a leaf spring 12 mounted on the upper side of the center side of the cross member 4, as shown in FIG. Fix it with the bolt (22) while 26) is raised.
The shock absorbers 30 and 32 are inclinedly fixed to one side of the left and right knuckle arms 8 and 9 and both ends of the cross member 4, respectively.
That is, the shock absorbers 30 and 32 may be installed while maintaining a proper inclination angle according to the space between the cross member 4 and the knuckle arms 8 and 9.
Suspension device made in this way absorbs the vertical vibration of the knuckle arms (8, 9) while the leaf spring (12) moves up and down about the point fixed to the cross member (4) when the vibration is transmitted from the road surface, The natural vibration of the leaf spring 12 is absorbed by the damping action of the shock absorbers 30 and 32.
The suspension device according to the present invention made as described above can reduce the number of parts, greatly reduce the installation space, and simplify the structure by using one leaf spring as the rear wheel left and right chassis springs. In addition, this can reduce the manufacturing cost.
In addition, the shock absorber can be mounted with a certain inclination angle, which is advantageous in design and maximizes space utilization.
