US 2023/0220911 A1 · VEHICLE DIFFERENTIAL LOCKING DEVICE (options)

Abstract

The claimed invention relates to the automotive industry, namely: to devices for locking differentials of vehicle driving axles with forced locking. The technical result is creating a differential locking mechanism facilitating a significant improvement of performance indicators in differentials using the claimed locking mechanism and the range expansion of such a differential use. The technical result is achieved by the locking device integrated into the differential, comprising the differential housing, semi-axle gears located inside the housing, and being in either “Locked” or “Unlocked” positions, consists of: locking elements shaped as a rotation body; through locking holes made in the differential housing; the recesses of semi-axle gear arranged on the semi-axle gear surface; ring lock-up clutch on the differential housing around the locking holes with locking elements, on the inner surface of which there are lock-up clutch grooves enlarging the contact spot area: “Lock-up clutch—locking element”.

A vehicle differential locking device integrated into a differential, including a differential housing, semi-axle gears located inside the housing, and the differential locking device being in either a “Locked” or a “Unlocked” positions, comprising:

locking elements shaped as a rotation body;
through locking holes made in the differential housing, that holds the locking elements with a possibility of moving in the locking holes along axes of these holes;
a recesses of the semi-axle gear arranged on a semi-axle gear surface;
a ring lock-up clutch on the differential housing around the locking holes with the locking elements, on an inner surface of which there are lock-up clutch grooves enlarging a contact spot area of ae pair:
“the lock-up clutch — the locking element”;
wherein the lock-up clutch is connected to a drive, with an ability to move along a differential rotation axis and with a possibility of stopping it in “Unlocked” and “Locked” positions.
