ZQ-774698 Transmission Synchronizer for SINOTRUK HOWO Heavy-Duty Trucks
The ZQ-774698 is a precision-engineered synchronizer assembly specifically designed for SINOTRUK HOWO series heavy-duty truck transmissions. As a critical component within the gearbox, it ensures smooth, clash-free gear shifting by equalizing the rotational speeds of gears and shafts before engagement. This part is essential for optimizing transmission performance, reducing driver fatigue, and prolonging gearbox lifespan in demanding commercial vehicle operations.
Key Features & Technology
Advanced Synchronization: Utilizes a double-cone or multi-cone friction design (specific to model variant) to maximize friction surface area, enabling faster and smoother gear synchronization under high-torque conditions.
High-Performance Materials: Manufactured from specialized alloy steels and bronze alloys for friction rings, offering exceptional wear resistance, thermal stability, and durability under extreme loads.
Precision Engineering: Features precisely machined blocking teeth, synchronizer rings (baulk rings), and synchronizer hubs to ensure accurate gear engagement and prevent grinding or premature wear.
Optimized Lubrication: Designed with grooves and chamfers to facilitate efficient oil flow across friction surfaces, ensuring consistent performance and cooling.
Enhanced Friction Coating: Often incorporates advanced surface treatments or coatings (like molybdenum or specialized compounds) on friction surfaces to improve shift quality and longevity.
