A planet gear carrier () for an automotive vehicle having a plurality of mounting regions (), mounting a respective planet gear (), and between the mounting regions (), at least one aperture () such as a through-hole () that weakens the planet gear carrier (), and when filled by a stiffening element () reinforces the planet gear carrier (). A planet gear carrier having installed planet gears, a spur gear differential comprising such a planet gear carrier as well as a spur gear differential comprising two planet gear carriers of the aforesaid type.

Support structure of a planet gear carrier

A double differential device for a vehicle which is of compact construction. The device has a longitudinal differential section with a longitudinal differential input, a longitudinal differential output, an axle output. It also has a transverse differential section with a transverse differential input and two driven outputs. The longitudinal differential output is connected with the transverse differential input, the longitudinal differential section and the transverse differential section are each a planetary spur wheel gear and are arranged coaxially with a common main axis of rotation. The longitudinal differential section has a longitudinal differential planet carrier, which carries a longitudinal differential planet set, and the transverse differential section has a transverse differential planet carrier, which carries a first and a second transverse differential planet set. The longitudinal differential planet carrier and the transverse differential planet carrier are arranged rotatable relative to one another, and the two driven outputs are driven suns.
