Sinotruk Howo Transmissions Gearbox Parts Range: Gear Synchronizer Gear Holder (Part No. WG2210100007)

Part Number: WG2210100007
Part Name: Gear Synchronizer Gear Holder (Also commonly referred to as Synchronizer Gear Holder or Synchronizer Hub)
Application: Sinotruk Howo Heavy-Duty Trucks
Function: This critical component is an integral part of the synchronizer assembly within the Sinotruk Howo manual transmission (gearbox). Its primary functions are:
Mounting Point: It serves as the central hub or carrier onto which the synchronizer rings (blocking rings), synchronizer sleeve, and associated springs/detents are assembled.
Spline Interface: Features internal splines that mesh precisely with the splines on the transmission gear it is mounted to (e.g., 3rd/4th gear, 5th/6th gear cluster).
Torque Transmission: Transfers engine torque from the selected gear, through its splines, to the synchronizer sleeve, and ultimately to the main output shaft when engaged.
Synchronization Surface: Provides the conical friction surface that the synchronizer ring contacts against during gear shifts, enabling the matching of speeds (synchronization) between the gear and the shaft for smooth, clash-free engagement.
