Hydromechanical Power Amplifier for Enhanced Torque and Speed
Here’s PatSnap Eureka !
Summary
Problems
Existing mechanical and hydromechanical systems face challenges in achieving sufficient speed of rotation and torque at the load output, particularly with low-power electric motors and high-inertia alternators, limiting the nominal operation of moving parts.
Innovation solutions
A hydromechanical assembly comprising an input motor, a hydraulic pump, a distributor, interconnected double-acting hydraulic jacks, a rack and pinion system, a reduction stage, and an alternator, where the rack and pinion system ensures rotational movement in a single direction, and the reduction stage multiplies rotational speed to amplify mechanical power.

General conflict description:
Principle concept:
If a low-power electric motor is used to drive a high-inertia alternator, then the system structure is simple, but the output power is insufficient to achieve the required rotational speed and torque
Why choose this principle:
The patent employs a hydraulic amplifier system where a hydraulic pump converts mechanical energy from the motor into hydraulic energy, which then actuates hydraulic cylinders to produce amplified mechanical output. This hydraulic transmission mechanism enables a low-power motor to drive a high-inertia alternator by multiplying both torque and rotational speed through the hydraulic amplification process
Principle concept:
If a low-power electric motor is used to drive a high-inertia alternator, then the system structure is simple, but the output power is insufficient to achieve the required rotational speed and torque
Why choose this principle:
The power amplification system is divided into distinct functional modules: a hydraulic pump unit, a distributor unit, hydraulic cylinder units, and a reduction stage. Each module performs a specific function in the power amplification chain, allowing the system to achieve complex power multiplication through coordinated operation of simpler subsystems

Abstract
Disclosed is a mechanical power amplifier assembly (100) characterised in that it comprises a motor (10) at the input, a pump (20) actuated by the motor, a distributor (30) supplied by the pump, a first cylinder (40a), a second cylinder (40b), the cylinders being connected to the distributor, a rack-and-pinion system (50), a reduction stage (60), and an alternator (90) at the output. The assembly allows the speed of rotation and/or the torque to be multiplied between its input and its output, the rack-and-pinion system (50) comprising a first rack (51a) secured to the rod of the first cylinder (40a), a second rack (51b) secured to the rod of the second cylinder (40b), a first pinion (52a) cooperating with the first rack, a second pinion (52b) cooperating with the second rack, and a transmission shaft (55) coupled to each of the pinions in a single direction of rotation S, the other direction of rotation being freewheeling.
