The automotive transmission system is a core component of the vehicle's powertrain, responsible for transmitting engine power to the drive wheels. During this process, it adjusts the magnitude, direction, and distribution of power to meet the vehicle's driving needs under varying operating conditions.
EEP's transmission system product line includes key components such as drive shafts, ball joints, bearings, clutch assemblies, and differential components. We are committed to providing high-precision, high-durability, original equipment manufacturer-grade products for front-wheel drive, rear-wheel drive, and all-wheel drive systems, ensuring smooth, reliable, and efficient power transmission.
The performance of the transmission system directly impacts the vehicle's power, fuel economy, ride quality, and handling stability.

Core Product Engineering Divisions
Clutch System Manufacturing
Our clutch assembly production encompasses pressure plate fabrication using diaphragm spring technology rated for torque capacities from 180Nm to 420Nm. Friction disc manufacturing employs organic facings with Marcel spring cushioning, copper-based materials for high-performance applications, and ceramic composites for commercial vehicle durability. Release bearing production includes hydraulic concentric slave cylinders (CSC) and mechanical throwout bearings with self-aligning capabilities. All clutch kits undergo engagement smoothness testing and thermal cycling validation.
CV Joint & Driveshaft Components
Precision CV joint wholesale programs feature Rzeppa-type constant velocity joints with hardened alloy steel ball cages, tripod joint configurations for plunging applications, and complete boot kit assemblies. Manufacturing processes include vacuum carburizing achieving surface hardness 58-62 HRC while maintaining core ductility. Axle shaft production covers solid shaft designs and tubular constructions with spline machining tolerances within 0.02mm. Dynamic balancing procedures eliminate vibration sources across operating speed ranges.
Transmission Mount & Linkage Systems
Wholesale transmission mount inventory includes hydraulic engine mounts with fluid-damped oscillation control, solid rubber mounts for commercial applications, and polyurethane performance upgrades. Shift linkage manufacturing encompasses cable assemblies with self-adjusting mechanisms, mechanical rod linkages with precision-ground ball ends, and selector fork components. Material specifications prioritize fatigue resistance through controlled steel chemistry and stress-relief heat treatments.
Synchronizer & Internal Gearbox Parts
Wholesale suppliers receive access to synchronizer ring sets featuring brass alloy construction with molybdenum coatings, carbon friction materials for enhanced durability, and complete hub assemblies. Gear manufacturing capabilities include helical gear cutting with profile grinding, differential spider gear sets, and bearing retainer components. Material traceability documentation accompanies shipments verifying alloy composition and heat treatment parameters.
Manufacturing Infrastructure & Certifications
Our 42,000 square meter transmission component facility operates 68 CNC machining centers with automated tooling changers and in-process measurement systems. Heat treatment department features controlled atmosphere furnaces, induction hardening equipment, and cryogenic processing capabilities. Quality laboratory houses coordinate measuring machines, hardness testing stations, and metallographic analysis equipment.
ISO 9001:2015 certification validates quality management systems while TS 16949 automotive supplement ensures process capability studies and advanced product quality planning. Component testing includes torque capacity validation, endurance cycling, noise-vibration-harshness characterization, and dimensional verification following PPAP Level 3 documentation requirements.
