Abstract: Convoluted boot seals for use on universal joints operating at relatively large angles with the side walls of some convolutions having a series of contact ribs which are formed thereon where abrasion might cause seal wear and failure. These ribs are flexible so that they can bend over when they contact an adjacent, relatively turning side wall so that direct sliding contact and resulting abrasion between adjacent side walls are eliminated.

Abstract: A differential gear unit for the drive axles of motor vehicles has a positive differential lock comprising a jaw clutch plate which is connected non-rotatably but movable axially with the differential case and which works in conjunction with a jaw clutch counterplate which is mounted non-rotatably and axially immobile on a differential gear drive shaft. The jaw clutch plate also serves as an armature for an electromagnet shaped as a ring magnet, which can be switched on and off manually. The jaw clutch plate is released from the jaw clutch counterplate by the preloaded spring means when the ring magnet is switched off. The electric circuit for controlling the ring magnet includes an electronic control unit developed as a velocity sensor which allows switching on of the ring magnet only below a predetermined velocity limit of the vehicle. Above this velocity limit the ring magnet switches off automatically.
