SITRAK C7H/C9H truck Synchronizer Cone Hub 1296.333.050 from sinotruk company
FUNCTION
1. Synchronized Speed for Smooth Shifting: At the precise moment of shifting, the synchronizer cone hub and its corresponding synchronizer ring establish firm contact via their conical surfaces. By harnessing frictional force, they rapidly bridge the rotational speed difference between the gear awaiting engagement and the target gear, bringing both to an identical speed. This allows the sliding sleeve to engage smoothly, thereby eliminating the gear clash and abnormal noises-typically associated with the "double-clutching" or forced shifting required in traditional non-synchronized transmissions.
2. Prevention of Gear Wear and Noise: Through the process of friction-based synchronization, the synchronizer cone hub effectively eliminates gear-end impact and gear-clashing phenomena caused by rotational speed discrepancies. This significantly reduces the wear rate of the transmission's internal gears, shafts, and bearings, while simultaneously achieving a marked reduction in shifting noise.
3. High Torque and High-Frequency Shifting Capability: Forged from high-strength alloy steel, the component is engineered to withstand input torques exceeding 2100 Nm-as found in the ZF 16S series transmissions-and to endure the thousands of daily shifting operations typical of heavy-duty trucks without succumbing to deformation or fatigue cracking. This ensures reliable synchronization performance even under the most demanding operating conditions, such as heavy-load hill climbing, frequent stop-and-go traffic, or high-speed overtaking maneuvers.
Advantages
| No. | Performance Advantage | Brief Description |
|---|---|---|
| 1 | Faster and Smoother Shifting | High-precision conical friction surface design enables extremely short synchronization time, resulting in virtually jerk-free and impact-free gear changes, delivering silky-smooth shifting even under high-torque heavy-load conditions, improving driving comfort and transport efficiency. |
| 2 | Significantly Reduced Wear and Noise | Effectively eliminates gear tooth clash and impact, greatly reducing wear rates on internal gears, shafts, and bearings of the transmission, while dramatically lowering shift-related noise, allowing the vehicle to remain quiet and reliable over the long term and extending major overhaul intervals. |
| 3 | Exceptional Load-Bearing Capacity | Made from high-strength alloy steel with special heat treatment and surface hardening, it reliably withstands input torques over 2100 Nm and thousands of daily shifts, making it ideal for demanding heavy-duty scenarios such as long-haul transport, heavy loading, and steep climbs without fatigue cracking. |
| 4 | Improved Overall Transmission Efficiency | Short synchronization process minimizes power interruption time, allowing more continuous and smooth power delivery from the engine to the drive wheels, reducing energy loss, enhancing fuel economy, and improving acceleration response, especially noticeable during hill starts or frequent overtaking. |
