Front shock absorber assembly introduce

Shock absorbers are mainly used to suppress the oscillation and impact from the road surface when the spring rebounds after absorbing vibration. When passing through uneven roads, although the absorbing spring can filter out the vibration of the road surface, the spring itself still has reciprocating motion, and shock absorbers are used to suppress this type of spring jumping. If the shock absorber is too soft, the body will jump up and down, and if the shock absorber is too hard, it will bring too much resistance, Obstructing the normal operation of springs. In the process of modifying the suspension system, hard shock absorbers need to be matched with hard springs, and the hardness of the springs is closely related to the weight of the vehicle. Therefore, heavier vehicles generally use harder shock absorbers. The device connected to the shock-absorbing crankshaft is used to counteract the torsional vibration of the crankshaft (i.e. the phenomenon of the crankshaft twisting due to the impact force of cylinder ignition). In the suspension system, vibration is generated due to the impact of elastic components, To improve the smoothness of car driving, shock absorbers are installed in parallel with elastic components in the suspension system. To attenuate vibration, hydraulic shock absorbers are commonly used in car suspension systems. Their working principle is that when relative motion occurs due to vibration between the frame (or body) and the axle, the piston inside the shock absorber moves up and down, The oil in the shock absorber chamber repeatedly flows into another chamber through different pores. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, converting the vibration energy of the car into oil thermal energy, which is then absorbed and dissipated into the atmosphere by the shock absorber. When the cross-sectional area and other factors of the oil channel remain unchanged, the damping force increases or decreases with the relative motion speed between the frame and the axle (or wheel), And it is related to the viscosity of the oil [1]. Shock absorbers and elastic components bear the task of cushioning and shock absorption. If the damping force is too large, it will cause the suspension elasticity to deteriorate, and even damage the shock absorber connecting parts. Therefore, it is necessary to adjust the contradiction between elastic components and shock absorbers (1) During the compression stroke (when the axle and frame are close to each other), the damping force of the shock absorber is relatively small, in order to fully exert the elastic effect of the elastic element and alleviate the impact. At this time, the elastic element plays the main role (2) During the suspension extension stroke (the axle and frame are far away from each other), the damping force of the shock absorber should be large and quickly absorb shock (3) When the relative speed between the axle (or wheel) and the axle is too high, it is required that the shock absorber can automatically increase the fluid flow rate to maintain the damping force within a certain limit, in order to avoid bearing excessive impact loads. Tubular shock absorbers are widely used in automotive suspension systems, and they can provide shock absorption in both compression and extension strokes, which is called bidirectional shock absorbers. New shock absorbers are also used, It includes inflatable shock absorbers and resistance adjustable shock absorbers)

Dongfeng Xiaokang C37 introduce

Appearance: The Dongfeng Xiaokang C37 has a sharp and angular exterior design. When you first see it, you will always feel a bit like the new generation Quanshun. The square and square shape adds a stronger business atmosphere to it. Basic parameters: The exterior dimensions are 4500 * 1680 * 1960mm, with a wheelbase of 3050mm. Compared with other competing models, the Dongfeng Xiaokang C37 should be considered a big block in micro passenger products. The vertically placed headlight assembly looks very personalized, The appearance of the Fangzheng is consistent with the overall style of the vehicle. The large intake grille adopts two thick horizontal bar designs, giving a domineering and tough feeling. Interior: The center console is wrapped in hard plastic, and according to the editing experience, the seams between various components are even without any burrs or other phenomena. The center console adopts a color combination of deep top and light bottom, which meets the aesthetic requirements of Chinese people. Space: The interior space of the Dongfeng Xiaokang C37 is still very good, Even for the 9-seat model with the largest number of seats, the interior space will not feel particularly cramped, and the middle two rows of seats can also be adjusted back and forth, which is more practical. Power: Dongfeng Xiaokang C37 is equipped with a 1.4L all aluminum engine, model DK13-06, the maximum power is 101 horsepower/6000 rpm, the maximum torque is 124N · m/5200 rpm, and the transmission is a 5-gear manual transmission. This engine uses a variable valve timing system, Fully meet the intake requirements of the engine at different speeds. In terms of configuration, the Dongfeng Xiaokang C37 comes standard with 185R14LT wide tires, aluminum alloy wheels, power steering, front electric windows, and child safety locks. In addition, the high-end models of Dongfeng Xiaokang are also equipped with leather seats and visual radar, and can also be equipped with ABS and driver's safety airbags
