Abstract: Abstract: Due to the braking torque un-adjustable and the large impact force during the braking process of conventional electro-hydraulic brake, the fluid dynamics theory is applied to analyzing the thrust mechanism caused by electro-hydraulic pusher. It shows that the thrust of the pusher can be adjusted by changing the rotational speed of the impeller, and then the different braking torque can be obtained to realize controllable braking process of the mechanical load. This conclusion is verified on the experimental platform of the electro-hydraulic brake performance.
