The challenges of modern transmission testing place ever growing demands on modern shift actuators. While a few years ago, enabling a secure shift of gears was sufficient, these days, realistically simulation of human gear shifting behaviour takes priority. The ATESTEO shifting actuator GSE 4.0 Highline supports the entire spectrum of gear shifting. The gear shifting unit GSE 4.0 Highline from ATESTEO is a highly dynamic shifting actuator for use on drivetrain and transmission test benches. The high-frequency control of force, position, and speed enables fully automatic and realistic shifting of all types of vehicle transmissions.
Highly dynamic simultaneous control of force and speed
The GSE 4.0 Highline shifting actuator consists of two linear motion units driven by servomotors for the shifting and selecting direction. Speed and position values are collected by the absolute encoder integrated in the servomotors. The determination of the shifting forces takes place through a customised force measuring device integrated in the gripper axis. To recognise the gear lever, the gripper is additionally equipped with a magnetic sensor. The height of the gear shifting actuator foot can be adjusted to adapt the robot to various assembly situations.
Displaying human shifting behaviour with the shifting actuator GSE 4.0 Highline
Experience from analysing human behaviour when shifting gears with the ATESTEO GSA system was the basis for developing gear shifting patterns of the force-controlled GSE 4.0 Highline. The highly dynamic simultaneous control of force and speed during the shifting event enables the simulation of how human drivers change gears.
