Product Introduction

1064001140 High-tensile Precision-machined OEM-compatible Drive Shaft for Geely EC-7

Product Advantage

1. 
   

   High-Tensile Steel Construction for Maximum Durability

   Our drive shaft uses high-tensile steel with a tensile strength of ≥800MPa (meeting SAE J2380 automotive standards), 20% higher than ordinary carbon steel. It undergoes 10,000+ fatigue tests at 3,000 RPM, ensuring no deformation or under high torque (up to 350N・m). This high-tensile steel drive shaft resists wear from long-term use, extending service life by 30% compared to standard drive shafts.

   
   

2. 
   

   Precision Machining for Zero Power Loss

   With CNC precision machining (tolerance controlled within ±0.05mm), the drive shaft’s joints and splines fit perfectly with other components. Test data shows it achieves 99.5% power transmission efficiency, minimizing energy loss during operation. This precision-machined drive shaft avoids abnormal noise or vibration (vibration amplitude ≤0.1mm), ensuring smooth driving even at high speeds.

   
   

3. 
   

   Corrosion-Resistant Coating for All-Weather Use

   The drive shaft features a multi-layer corrosion-resistant coating (zinc-nickel plating + polymer sealant) that passes 500+ hours of neutral salt spray testing (per ISO 9227). It remains rust-free in humid, snowy, or coastal environments, solving the common issue of rust-induced failure. This weather-resistant drive shaft maintains stable performance in -40℃ to 120℃ temperature ranges, adapting to diverse climates.

   
   

4. 
   

   OEM-Compliant Design for Easy Installation

   Designed to match OEM specifications, the drive shaft’s mounting holes and dimensions align 100% with standard brackets—no modifications needed. It comes with pre-greased joints, allowing users to complete installation in 30 minutes (per automotive repair industry average time). This OEM-compatible drive shaft eliminates fitment risks, a top concern for customers, and works seamlessly with existing transmission systems.

   
   

5. Vibration-Damping Structure for Enhanced Comfort

   Integrated with a rubber damping sleeve (Shore hardness 60±5A) at the intermediate support, the drive shaft reduces vibration transfer by 40% (tested on automotive NVH platforms). It lowers in-cabin noise by 3-5 dB during acceleration, improving driving comfort. This vibration-damping drive shaft also reduces wear on connected components (like bearings), cutting maintenance costs by 25% annually.

Technical Parameters

Product Uses

Here are specific application scenarios of drive shaft:

1.Daily Urban Commuting

Urban driving involves frequent acceleration and deceleration, requiring stable torque transmission. Our drive shaft, with 99.5% transmission efficiency (per SAE J1962), ensures smooth power delivery. It resists wear from stop-and-go traffic, maintaining performance for 80,000+ km (normal use), reducing the risk of sudden transmission issues during daily trips.

2.Long-Distance Highway Travel

Highway driving demands consistent performance at high speeds (up to 120km/h). The drive shaft’s rotational balance (≤5g·cm at 3000 RPM) minimizes vibration, lowering in-cabin noise by 3-5 dB. Its high-tensile steel (≥800MPa) handles continuous torque (up to 350N·m), ensuring reliable power transfer for 4+ hour non-stop drives.

3.Off-Road & Rough Terrain Driving

Off-road conditions expose components to dust, impacts, and uneven loads. The drive shaft’s corrosion-resistant coating (500+ hours salt spray test, ISO 9227) prevents rust, while its 10,000+ fatigue test cycles withstand. It maintains torque stability on gravel or muddy roads, avoiding power loss in tough environments.

4.Cold & Humid Climate Use

In -40℃ to 120℃ temperature ranges, the drive shaft’s material and coating remain stable. It resists freezing or deformation in cold winters, and its polymer sealant blocks moisture in humid areas. This ensures consistent performance year-round, solving climate-induced transmission problems common with ordinary drive shafts.

Product Operate Guide

1. Ensure the vehicle is on a level surface. Disconnect the old drive shaft from the transmission and differential (use a torque wrench to loosen bolts per 25-30 N·m standard).

2. Align the new drive shaft’s splines with the transmission, then fasten bolts to 28 N·m (per automotive repair standards).

3. Check rotational flexibility; start the vehicle to test for abnormal noise. Inspect every 10,000 km (industry maintenance advice) to maintain performance.
