Light truck damping system

Abstract

The invention discloses a light truck damping system. The light truck damping system comprises a seat skeleton, the seat skeleton comprises a fixed frame and a movable frame, and sliding rail assemblies are mounted on the two sides of the fixed frame in an integrated mode. A damping mechanism is mounted on the movable frame, the movable frame comprises a damping upper frame and a damping lower frame, and the damping upper frame is arranged on the backrest position of the seat skeleton. The damping lower frame is arranged above the fixed frame, the damping mechanism comprises two damping springs, a damper and two adjusting levers, and the adjusting levers are arranged on the two sides of the damping upper frame. An adjusting hand wheel is arranged on the side face of the damping lower frame, and the adjusting hand wheel pulls the damping springs and the damper to move forwards through pulling lines and pulls the adjusting levers to achieve rigidity adjustment. In this way, according tothe light truck damping system, through backrest-type damping, the damp utilization rate is increased, the damping thickness is decreased, the available space of a truck body is large, friction forceof adjustment of the hand wheel is small, the adjusting comfort degree is high, and the rigidity adjusting range is increased.

Description

technical field [0001] The invention relates to the technical field of automobile accessories, in particular to a light truck damping system. Background technique [0002] Driven by the intensified domestic GDP rebound trend, the sales volume of light trucks in China has been increasing year by year. Light trucks are mainly used for urban logistics, and the demand is mainly affected by the urban and rural economies, while less affected by fluctuations in fixed assets and exports. Sales volatility Small, showing a certain weak periodicity. GDP bottomed out in the fourth quarter of 2016 and gradually stabilized, and light truck sales turned positive during the same period. [0003] In freight trucks, the standard for light trucks is generally a truck with a load capacity of 0.86-4 tons. Because the materials and finished products that need to be transported in heavy industry are of relatively high quality, the use of light trucks in industry is not very common. However, in r...

Problems solved by technology

[0005] At present, the old shock absorbers in China are mostly installed at an angle, and the damping cannot fully function, and the damping life is short. At the same time, the mechanical shock absorber takes up a lot of space, and the space utilization rate is relatively low; the stiffness adjustment range is small, and the comfort It is relatively low and cannot realize all the functions of the seat base, and cannot adapt to all types of light trucks on the market. In view of these problems in the mechanical shock absorption of light truck seats on the market, our company has developed a universal light truck mechanical shock absorber that can solve the above problems. shock
