A McPherson front suspension rigid-elastic coupling model was established by ADAMS/CAR, and the sensitivity of the suspension rubber bushing stiffness was analyzed by ADAMS/insight. The bushing stiffness, which has great influence on wheel positioning parameters, was selected as the design variable, and the minimum variation of wheel camber Angle, front beam Angle, kingpin internal Angle and kingpin rear Angle was taken as the objective function. The wheel positioning parameters were improved by experimental design and multi-objective optimization method. The results show that the kinematic characteristics of suspension can be effectively improved by changing the axial stiffness, torsional stiffness, radial stiffness, axial stiffness and torsional stiffness of front bushing on the lower control arm shaft. After optimized design, the suspension performance is obviously improved compared with the original scheme.

U type is commonly used in truck, it is used to stabilize the car chassis and frame. The leaf springs, for example, are attached with U-bolts.
1. Material characteristics, density, bending strength, impact toughness, compression strength, elastic modulus, tensile strength, temperature resistance, color according to the use of environment.
2 materials commonly used carbon steel Q235A Q345B alloy steel stainless steel and so on. The stainless steel material is 201 304, 321, 304L, 316, 316L.
3. National standard for U-bolts: JB/ZQ4321-2006.
Step 4: Material
U-bolts are divided into carbon steel Q235, Q345 alloy steel, stainless steel 201 304 316 and so on, that is, carbon steel and stainless steel

The function of the rear tail light is to have sufficient luminous intensity so that the rear lamp of a car can clearly distinguish the signal for drivers of other vehicles or pedestrians even in bright daylight. At this time, some netizens may ask whether driving at night will be very dazzling. In fact, the light emitted by the back tail lights will not cause glare and discomfort to drivers of other vehicles or pedestrians.

the stabilizer link damage abnormal sound, how to replace the stabilizer link, the role of the balance rod
Balance rod rubber sleeve damage not only abnormal noise and affect safe driving, if there is a ding dong like a drum sound on the bumpy road, it may be damaged.
Because the car is also a little mileage, steering wheel, chassis abnormal sound, so I tried to replace the balance pole, the result still did not eliminate abnormal sound, this video is only as a basic operation reference to replace the balance pole, check to determine the balance pole is wrong before replacement

Transverse stabilizer bar, also known as anti roll bar, is a kind of auxiliary elastic element in automobile suspension. The lateral stabilizer bar is a torsion bar spring made of spring steel in the shape of a "U" that sits across the front and rear ends of the car. The middle part of the rod body is hinged with a sleeve and the frame, and the two ends of the rod are respectively fixed on the lower arm of the left and right suspension.
When the car is turning, due to the role of centrifugal force will cause the body roll, resulting in the inner wheel suspension stretch, the outer wheel suspension compression, resulting in the anti-roll bar bar torsion, produce a lot of torque, reverse action on the suspension, prevent the body in the turn too large lateral roll and improve ride comfort.

The use of the Bushings can reduce the wear, vibration and noise of the equipment, and has the effect of anti-corrosion. The use of stabilizer link bushing can also facilitate the maintenance of mechanical equipment and simplify the structure and manufacturing process of the equipment. The role of the bushing in actual work is closely related to its application environment and purpose.
There is also a sway link bushings between the connecting rod and the crankshaft. Its main functions are shock absorption, sound insulation, fatigue reduction, and extended service life. It plays a vital role in the driving stability of the vehicle.
Therefore, the connecting stabilizer bar link bushing has the following functions. Protect the connecting rod, prolong its service life, save engine maintenance costs, and reduce engine economy.

The upper and lower control arms of the automobile shock absorber will be connected by sway bar end link bushings. When the vehicle passes through bumpy roads, high-frequency vibrations will be generated. In addition to shock absorbers and tires that can absorb shocks, various suspension stabilizer rubber bushing can also absorb part of the shocks. In this way, the transmission of vibration into the cockpit is avoided as much as possible, and the comfort performance of the vehicle is improved.

The suspension stabilizer bar, also known as the stabilizer bar end link, is an auxiliary elastic component in the car suspension. Its function is to prevent the body from excessive lateral roll when turning, prevent the car from rolling over and improve ride comfort.

Leaf springs: It is composed of multiple steel plates with unequal lengths and unequal curvatures. After installation, the two ends naturally bend upwards. When the impact force from the road to the wheels comes, the composite leaf spring will deform, which will play the role of cushioning and vibration reduction, and also play the role of guiding and transmitting force when arranged longitudinally. Most of the non-independent suspensions use parabolic springs as elastic elements, which can save guide devices and shock absorbers, and have a simple structure.
Leaf springs are the most widely used elastic element in automobile suspension. It is composed of several alloy spring pieces of equal width but unequal length (the thickness can be equal or not). An approximately equal strength elastic beam.
