The differential based on the herotor pump is for liquid (hydraulic) and friction simultaneously. The torque transmission, instead of the spring, is controlled by the liquid pressure that is injected by the pump that is structurally relevant to the type of herotor. Inside the pump are the gears (which is why the pump is often referred to as the gear-grade pump). The jagged wheel connected to the pump is connected to the shaft. When the speed of rotation of the shell and the gear rotation is the difference, the pump compresses the working fluid inside the pump. The pressure of the liquid is sufficient to transmit the torque to the wheel more strongly with the surface. A system based on a herothorn pump is subject to a hydraulic fluid. These limitations shall ensure, on the one hand, the reliable operation of the host, on the other hand, a gradual, smooth increase of the torque without mechanical shocks. The most modern systems based on the herothorn pump operate under the control of the computer, the regulating capacity at the exit. Gerothorn Pump

The herotor pump, as well as other types of hydraulic pumps, is a two-way pump; that is, it is capable of operating both in pump mode and hydro-motor mode. When the torque is needed to be increased, the machine operates in pump mode. If it is necessary to reduce the transmission of the torque to the shaft, the pump shall be operated as a hydraulic engine.
Example of interaxial differential lock based on the herotor pump
Self-balancing differential based on the herotor pump is installed on modern Jeep SUVs. The system is called Van-Lock. Differential lock, as in other systems, is based on increasing friction between the friction packages, but the spring role is played by a herothorn pump, which is driven from the six-dimensional semi-axis. when one wheel starts to slip, there is a difference in the wheel rotation, and the seal pump will start to move the oil from one container to the other. The energy of the resulting pressure is used for the information of the friction, which blocks the differential. The faster the spinning wheel is spinning, the more intense the wheels are blocked.
Advantage and disadvantages of differential hypertension based on the herotor pump
Differential tension on the basis of the herothorn pump is simple from a constructive point of view, and therefore reliable and not too expensive in production. These qualities make it possible to say that the potential service of such a node is large enough. The downside of the system is that there are severe limitations in the pump as well as in any hydraulic system, and that there is no hard-machine-pressure differential on the basis of the herothorn pump.
