Product Description
Product Introduction
-
Structure: An integrated assembly consisting of a high-strength nickel-chromium alloy steel hub, sliding sleeve, copper-based dual-cone synchronizer rings, and spring-loaded shift blocks. The hub and sleeve feature carburized and hardened teeth (HRC 58–62) for extreme wear resistance, while the dual-cone synchronizer rings use a friction-enhancing copper alloy with precision-machined cone surfaces to double synchronization capacity.
-
Performance: The dual-cone friction design rapidly equalizes the speed of 3rd/4th gears with the main shaft, eliminating gear impact and enabling smooth, shock-free shifts. The high-hardness teeth ensure reliable torque transmission under heavy loads, and the spring-loaded blocks maintain precise alignment between the sleeve and hub, ensuring consistent performance even in harsh operating environments.
Core Function
-
3rd/4th Gear Synchronization: Uses dual-cone friction to match the rotational speed of 3rd/4th gears to the main shaft, eliminating gear clash during shifting.
-
Smooth Gear Engagement: Enables shock-free meshing of the sliding sleeve and gear teeth, improving shift quality and extending component life.
-
Torque Transmission: Once synchronized, the sliding sleeve locks onto the gear, transferring torque from the main shaft to the output.
