Hydraulic differential
First Claim
1. Hydraulic differential comprising:
- a drive gear, two volumetric hydraulic clutches, a carrier housing and two output driven shafts, wherein both hydraulic clutches have a common drive part formed as a casting, in which the driven parts with immovably connected driven shafts are placed, and each of the hydraulic clutches has its own loop of circulating channels, which are separated into suction sides and discharge sides by means of a common gate unit, containing a cylindrical bed parallel to the common axis of rotation of both clutches, were a cylindrical gate with two openings is placed into the bed between two springs, and two guide channels connect both ends of the cylindrical bed with the discharge sides of the circulating channels, with the suction sides thereof connected to volumetric compensators.

Abstract
The present invention relates to axle and intermediate differential mechanisms applicable in vehicles. The inventive differential distributes the torque to the driven shafts automatically and in proportion to the loadings without mounting of any additional control means and actuating means. The proposed construction includes two hydraulic volumetric clutches having a common drive part, in which the driven parts with immovably connected driven shafts are placed. Each of the hydraulic clutches has its own loop of circulating channels, which are separated by means of a common gate unit, containing a cylindrical gate with two openings. Two guide channels connect the discharged sides of the circulating channels, the suction sides of which being connected to volumetric compensators. The gate blocks hydraulically both clutches when the loads on the driven shafts are equal, and releases the less loaded shaft in case of breaking the balance proportionally to the loading.
