大を必要とするという欠点を持つている。Known bevel gear differentials of this type (Austrian Patent No.
No. 380838), a differential case is fitted with a moveable switching sleeve on the neck surrounding a wheel drive shaft which is connected to the bevel gear. The switching sleeve is configured as a pawl sleeve, which pawl is guided by a slit parallel to the axis of the differential case and engages in a recess in the back of the corresponding bevel gear for differential locking. There is. These recesses are also engageable with a differential stop that is provided on the back of the bevel gear and is connected to the wheel drive shaft so as not to rotate relative to it. In any case, it has the disadvantage that the structure is relatively complex and requires a significant increase in the dimensions of the differential, especially in the direction of the wheel drive shaft.

At least one differential pawl extending in a direction perpendicular to the central axis of the shaft is supported, and for differential locking, the differential pawl is about the central axis of the shaft supporting the differential pawl. Swing from a neutral intermediate position to engage the teeth of both large bevel gears, the moveable switching sleeve fits over the differential case, and the differential stop pawls engage the differential case. It engages the switching sleeve via a pin-shaped projection that extends through a slit.

れる。Since the differential pawl is supported on the shaft of the bevel gear between both large bevel gears, no additional structural space is needed for this differential pawl and it is not In any case, the existing space is used. Therefore, without increasing or weakening the conventional differential that cannot be stopped,
It can be modified into a differential device that can be stopped differentially. Further, since the common shaft that supports both small bevel gears is also used as the shaft that supports the differential stop claws, an additional support shaft for the differential stop claws is unnecessary. Furthermore, since the differential stop claws directly engage the teeth of the large bevel gear, the differential device can be positively and completely differentially stopped, and an additional intermediate member for differential stop is not required. Since a switching sleeve movable alongside the driving bevel gear is provided on a suitable cylindrical differential gear case, and a slit for penetrating the pin-shaped projection of the differential stop pawl is provided on the differential gear, the technique is required. Expenditure is reduced to a minimum.
