Abstract

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.
