INTRODUCTION
ZF 4HP 16 AUTOMATIC TRANSAXLE
The ZF 4 HP 16 is a four–speed automatic transaxle de-
signed for cars with front–wheel drive and a transversely
mounted engine.
The transaxle has a hydrodynamic torque converter with
a controlled slip lock–up clutch.
A planetary gear train establishes the mechanical gear ra-
tios. The integral constant ratio can be adapted to the en-
gine’s power output and the vehicle’s weight. The elec-
tronic–hydraulic control makes controlled power shifts and
various shift programs possible. In selector lever position
”P”, the output is locked mechanically.The special feature of this transaxle is that it operates with-
out freewheels. Shifting between individual gears takes
place by means of overlapping clutch engagement and re-
lease.
The advantage of overlap shifting is as follows:
– The transaxle can be of more compact design
and is lighter on account of the absence of free-
wheels and the lower number of shift elements
– Lower drag losses, i.e. higher efficiency
– Lower peak torques acting on the components
and driveline.
However, overlap shifting necessitates high–performance
hardware and software, and precision engine signals.
