Thrust Rod Assembly
Core Performance
Ultra-high load-bearing capacity: Utilizing the integral forging process of 42CrMo high-strength alloy steel, the tensile strength is ≥ 1150 MPa, the impact energy is ≥ 45 J, and it can withstand ± 15 kN high-frequency alternating loads.
Outstanding fatigue life: After 1 million fatigue tests, there is no fracture, and the service life is 50% higher than the industry standard, meeting the requirement of no major repairs for commercial vehicles for 100,000 kilometers.
Precise positioning accuracy: It is once formed by a numerical control machining center, with a size tolerance of ± 0.02 mm, ensuring precise connection between the axle and the frame.
Excellent environmental adaptability: After neutral salt spray test for 720 hours, there is no rust, and it can work stably in extreme temperature environments ranging from - 40°C to + 120°C.
Main Applications
The thrust rod is a core structural component of the chassis suspension system of commercial vehicles, connecting the frame and the axle, and is mainly applied to:
Heavy-duty trucks, semi-trailer tractor units, dump trucks, mixer trucks
Buses, school buses, tourist buses
Construction machinery, mining machinery, special vehicles
Its core function is:
Transmitting traction force, braking force and reactive torque to ensure efficient power transmission
Limiting the front-back and left-right displacement of the axle to prevent driving deviation and abnormal tire wear
Enhancing the vehicle's anti-roll ability, improving the stability of vehicle turning and emergency lane changing
Balancing the load of the suspension to improve the comfort and passability of the vehicle on bumpy road conditions
Product Features
Dual structure options: Provide I-type straight thrust rods and V-type thrust rods for different vehicle models and working conditions
Integral forging process: The thrust rod shell adopts integral forging technology, effectively avoiding the risk of loosening and disengagement at the riveted joints, and has higher structural strength
Cross-shaped steel connecting rods: The V-type thrust rods adopt a cross-shaped steel connecting rod design, with more uniform force distribution and stronger torsional performance
Multiple anti-loosening designs: Adopting aerospace-level anti-loosening technology to completely solve the problem of loosening and failure of threaded fasteners under strong vibration conditions
Core Highlights
✅ Heavy-duty working environment expert: Designed for harsh working conditions such as mines and construction sites, capable of withstanding continuous impacts under 30% overload
✅ Lightweight design: Utilizing topology optimization technology, the weight is reduced by 9% while ensuring strength, effectively reducing vehicle fuel consumption
✅ Full series coverage: With over 2,000 models, covering all mainstream heavy truck models in China and abroad, available for immediate supply and same-day delivery
✅ Warranty commitment: All thrust rod assemblies come with a 18-month or 150,000-kilometer extended warranty, and free replacement for any quality issues
Torque Rubber Sleeve (Push Rod Sleeve)
Core Performance
Excellent shock absorption and buffering: Utilizing imported high-elasticity natural rubber with a Shore hardness of 73-76 degrees, it can effectively absorb over 90% of road vibrations and impacts
Super strong fatigue resistance: After 500,000 times of torsional fatigue tests, there are no cracks, and the anti-tear strength is ≥ 25kN/m, with a lifespan that is 2-3 times that of ordinary products
Large-angle oscillation capability: The maximum oscillation angle is ±15°, and the maximum rotation angle is 360°, fully meeting the movement requirements of vehicles under complex road conditions
Precise torque control: The initial torque error is controlled within ±5%, ensuring precise vehicle control and smooth driving
Main Applications
The torque rubber sleeve is installed at both ends of the push rod and is a key elastic component connecting the push rod to the frame / axle. Its main functions are:
Buffering and shock absorption, reducing damage to the chassis structure caused by road impacts
Allowing the push rod to rotate and oscillate relative to the axle / frame
Reducing noise and improving driving comfort
Protecting the push rod itself and extending its lifespan
Product Features
Patented self-lubricating sleeve technology: An additional self-lubricating sleeve is added between the ball and the elastic body, forming a sliding friction pair, completely solving the problem of traditional products' rubber being prone to tearing and wearing out quickly
Overall forged pin shaft: The pin shaft is forged from 40Cr alloy steel and undergoes quenching and tempering treatment, with high strength and good toughness, and is not prone to fracture or deformation
Multi-layer composite structure: From the inside out, it consists of the pin shaft, self-lubricating sleeve, elastic body, and outer ring. The structure is scientific and the force is distributed evenly
Double sealing design: Equipped with high-quality dust-proof rubber covers, effectively preventing dust, mud, and water from entering, and prolonging the lubrication cycle and lifespan
Core Highlights
✅ Exclusive patented technology: Possessing independently intellectual property rights' self-lubricating sleeve technology, with a friction coefficient reduced by 60% and a lifespan increased by 3 times
✅ Imported rubber material: Using Malaysian imported natural rubber, with added anti-aging and anti-ozonation formulas, which does not age and harden at high temperatures
✅ Precise vulcanization process: Using high-temperature and high-pressure overall vulcanization technology, the bonding strength between rubber and metal is ≥ 8MPa, never detaches
✅ Easy maintenance: Can replace the torque rubber sleeve separately, without the need to replace the entire push rod assembly, significantly reducing maintenance costs
