Triple shock absorbers stabilize loads
The persistently high loss rate in fruit and vegetable transport often stems from incompatibility between the vehicle's shock absorption system and the operating conditions. Traditional motorcycle shock absorbers, when applied to freight tricycles, present significant drawbacks: their linear damping curves struggle to adapt to alternating loads and empty loads, resulting in an empty vehicle bounce rate exceeding the standard by 45%. While external spring shock absorbers offer basic damping resistance, their open spring structure is susceptible to intergranular corrosion in humid environments, resulting in an average service life of only 1,800 kilometers. More expensive shock absorbers with coil springs, while providing rigid support, sacrifice comfort in light-load conditions due to the lack of adjustable preload. This, in turn, increases the incidence of hand vibration syndrome in drivers by 32%.
This axially adaptive shock absorber system achieves breakthroughs through three technological innovations:
Core Technology Architecture
① A dual-mode hydraulic valve assembly enables stepless switching between no-load flexible damping and heavy-load rigid support.
② The titanium alloy spring assembly is coated with a nano-ceramic coating, improving weather resistance by 270% compared to traditional spring shock absorbers.
③ An integrated brake shock absorber module simultaneously controls braking torque distribution.
Third-party testing:
1. Compared to motorcycle shock absorber systems, it maintains 76% of its initial travel margin under a 300kg load.
2. Compared to shock absorbers with coil springs, the no-load vibration transmissibility is reduced to the safety threshold specified in ISO 2631-1.
3. Braking stability meets ECE R78 regulations, fully meeting the performance requirements of brake shock absorbers.
Maintenance Procedures
① Check the hydraulic oil level and quality every 2000km.
② Quarterly inspect the integrity of the spring assembly's sealing end cap.
③ Self-adjustment of the damping valve assembly's preset parameters is prohibited.
(Engineering verification has shown that vehicles equipped with this system, transporting fragile goods on gravel roads in wholesale agricultural markets, have reduced their breakage rate from 17.6% to 2.3%)
