Fig. 2 is the side structural schematic diagram after the present invention opens.
Fig. 3 is overlooking structure diagram of the invention.
Specific embodiment
Present pre-ferred embodiments are provided with reference to the accompanying drawing, in order to explain the technical scheme of the invention in detail.
As shown in Figure 1 to Figure 3, automobile double fork arm type equal independent suspension device of the present invention includes upper swing arm 1, lower swing arm 2, driving
Semiaxis 3, semiaxis oil sealing 4, retarder 5, stabilizer bar 6, helical spring 7, damper 8, wheel axletree bearing seat 9, flexural pivot 10, connecting rod
11, wheel 12, lengthening connecting rod 13, bolt 14, link block 15, upper swing arm 1 are located at the upside of lower swing arm 2, one end of upper swing arm 1
It is connected with one end of damper 8, one end of lower swing arm 2 is connected with wheel 12, and retarder 5 is located at the other side of link block 15, even
Bar 11 is connected with wheel 12, and jack shaft 3 is connected by semiaxis oil sealing 4 with retarder 5, stabilizer bar 6 and lengthening connecting rod
13 are connected, and helical spring 7 is located at the outside of damper 8, and wheel axletree bearing seat 9 is connected with wheel 12, and flexural pivot 10 is located at helical spring 7
Upside, bolt 14 fixes with 1 phase of upper swing arm, and link block 15 is located at the other side of lower swing arm 2, and stabilizer bar 6 is located at connection
The other side of block 15.
The building method of automobile double fork arm type equal independent suspension of the present invention the following steps are included:
Step 1, double fork arm type equal suspensions are made of upper and lower two Length discrepancy control arms and column support type hydraulic damper；
Step 2, one end of upper suspension arm are connected to pillar damper, and the other end is connected to vehicle body；
Step 3, one end of lower control arm is connected to wheel, and the other end is then connected to vehicle body；
Step 4, upper lower control arm are also connected by a connecting rod, this root connecting rod is yet connected with wheel simultaneously.
The stabilizer bar 6 is torsion-bar spring, can be in not automobile turning, and body roll, two sides suspension is beated not
Unanimously, outboard axle can press to stabiliser bar, and stabiliser bar will be distorted, and the elastic force of shaft can prevent wheel lift, to make

The shape for lengthening connecting rod 13 is cylinder, this spline structure is simple, easy for installation, manufacturing cost is low.
The shape of the flexural pivot 10 is round, such long service life, and quality is secured.
Working principle of the present invention is as follows: two swing arms up and down of double fork arm type equal suspensions can accurately position each of front-wheel
Kind parameter, allows wheel to can be good at close proximity to ground, stronger lateral stiffness provides good lateral support, Nose Wheel Steering again
When, upper and lower two yokes can absorb cross force suffered by tire simultaneously, in addition the lateral stiffness of two yokes is larger, so turning
It rolls smaller.Using upper and lower Length discrepancy yoke, allows wheel that can change camber angle automatically when moving up and down and reduce wheelspan change
Change and reduce tire wear, and the adaptive road surface of energy, tire-contact area is big, and patch ground property is good.The control up and down of double yoke suspensions
Arm can play the effect of offsetting horizontal force, this makes pillar damper be not subjected to horizontal force, and only copes with wheel
Shake up and down, on bend have preferable directional stability.
In conclusion the present invention can allow wheel that can change automatically camber angle when moving up and down and reduce wheelspan change
Reduce tire wear, and the adaptive road surface of energy, tire-contact area is big, and patch ground property is good, can provide for vehicle body lateral well
Support.
