Leaf Spring Shock Absorber
leaf spring shock absorber
Leaf Spring Shock Absorber is a professional damping component integrated with leaf spring elasticity and shock absorption functionality, widely used in automotive, commercial vehicle, and engineering machinery suspension systems. As a core part of the vehicle suspension, it combines the load-bearing capacity of leaf springs with the vibration-damping performance of shock absorbers, solving the pain points of poor stability, weak load-bearing capacity, and short service life of traditional single shock absorbers-becoming an indispensable component for heavy-duty vehicles, trucks, buses, trailers, off-road vehicles, and construction machinery.

Core Function & Performance Details
Super Strong Load-Bearing & Stability
High load-bearing capacity: Multi-layer models can bear 5000-50000N, while parabolic models can bear 3000-30000N, meeting the needs of light, medium, and heavy-duty vehicles[8]. The stacked leaf design and rigid structure ensure the vehicle remains level even under full load, preventing sagging or tipping during transportation.
Premium Quality & Long Service Life
High-quality materials: Adopts 60Si2MnA/55Cr3 spring steel and seamless steel pipes,after strict heat treatment and quality inspection, ensuring high tensile strength (≥1275MPa) and fatigue resistance[1]. The leaf spring undergoes 2×10⁶ times four-point bending fatigue test without cracks, and the shock absorber passes 10⁵km equivalent durability test.
Energy-Saving & Cost-Effective
Lightweight design: Parabolic and composite models are 30-80% lighter than traditional multi-layer steel models, reducing vehicle unsprung mass and improving fuel efficiency by 5-10%[9]. This aligns with global lightweight trends and helps customers reduce long-term operating costs.
