A power assist element for arrangement in a synchronizer hub of a transmission synchronization device includes a base body, which has a height, a longitudinal extension and a lateral extension, and which in the direction of the longitudinal extension comprises includes two opposite, distal end sections. In at least one end section a functional surface is formed, which in the installed state cooperates with the synchronizer hub. On the base body between the two distal end sections a central elevation is formed for engagement in a sliding sleeve groove on a bottom of a sliding sleeve. The central elevation includes at least one additional functional surface which can be brought into active connection with the sliding sleeve. The functional surface in the distal end section(s) is at an acute angle to the greatest longitudinal extension of the base body and oriented at an angle to the longitudinal extension.

Power assist element

The invention relates to a synchronization piece which, as part of a servo synchronization system comprising a sliding sleeve, a clutch body, a synchronizer ring and an idler gear, can synchronize a transmission having toothed wheel gears. The invention furthermore relates to an entire synchronizing system having a synchronization piece according to the invention. A full-servo synchronization system is also presented.

Transmission synchronizing system, in particular, in the form of a servo synchronizing system
