The article presents the transmission of a truck, where innovative repair kits of the driveshaft crosspiece
are used. The crosspiece is an element of the transmission, and transmits all the torque from the gearbox to the
wheels of the car, therefore it is a heavily loaded part. A mathematical model has been developed that describes
in detail the process of changing the size of a movable conical spring insert in a sliding bearing used in the
mechanism of the cardan shaft crosspiece. The innovative repair kit is designed to improve performance by
introducing an elastic intermediate element into the bearing. This element is a movable insert in the form of a
helical or conical spring, and its compressible force is adjustable. This creates a tight seal on the working
surfaces, preventing oxidative processes and activation of microplastic deformation of the surface.
