In this example, a complete design for a tailgate with spindle drive is presented. For this purpose, holding forces are taken into account under multiple constraints such as different ground inclinations, an optional snow load, frictions, a clutch, overload cases, safety margins, efficiency factors, etc.
To observe direction-dependent influences, the complete opening process and the complete closing process are evaluated in real time at the same time using compressed time simulation.
The spindle drive consists of a fully configured spindle and two fully configured springs as additional energy storage elements (general support + popup aid). What is shown here with a one-bar system can be easily transferred to an arc hinge, a four-bar system or a different multi-bar system.
