Product Description
Product Introduction
Crafted from high-strength ductile iron (QT500-7) via precision sand casting and CNC machining, this transmission auxiliary case housing is engineered to endure extreme mechanical stresses in heavy-haul scenarios. Its integrated dual-cavity structural design is optimized for the layout of high/low range gear sets, with precision-machined mounting faces, bolt hole arrays and bearing bores that strictly comply with OE tolerance standards (±0.02mm). The housing undergoes normalized heat treatment to eliminate casting internal stress, paired with anti-corrosion black paint coating for enhanced durability in harsh working environments. Key features include a sealed oil sump structure, integrated shift rail guide holes and reinforced rib design at stress concentration points, ensuring reliable support for internal transmission components while facilitating efficient lubrication and heat dissipation.
Core Function
-
Acts as the rigid structural foundation of the transmission auxiliary case, providing precise positioning and stable mounting for range gears, synchronizers, shift forks and bearings.
-
Forms a sealed lubrication cavity to store transmission oil, ensuring continuous lubrication of internal moving parts and preventing oil leakage and contamination ingress.
-
Bears and distributes multi-directional dynamic loads generated during gear shifting and torque conversion, protecting internal components from deformation and damage.
-
Serves as the mounting interface for the transmission main case, rear extension housing and shift control mechanism, ensuring the integrity and coaxiality of the entire transmission system.
-
Enables direct OE replacement, with perfect dimensional compatibility to ensure quick assembly and consistent performance with the original transmission assembly.
