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

A power branching transmission suitable for motor vehicles having an internal-combustion engine which drives an input shaft of the power branching transmission has several branches comprising at least one power shift transmission with a number of gears and has an output shaft. For the comprehensive optimization of the power branching transmission, at least one of the branches is equipped with a control device by means of which, during the starting operation of the motor vehicle, the rotating direction of the output shaft can be changed, and during the starting operation and with shifted gears of the power shift transmission connected with the input shaft, by way of the control device, the rotational speed of the output shaft can be continuously influenced.
