Abstract:
A hydraulic balanced braking system comprising:two oil pressure cylinders; two hydraulic brakes driven by said two oil pressure cylinders to perform a braking movement; an oil-pressure balance unit situated between and connected with said two oil pressure cylinders and said two hydraulic brakes, said oil-pressure balance unit further comprising a main body, two parallel oil cylinders, lower ends of said oil cylinders each being connected to a corresponding one of said hydraulic brakes, an inlet at an upper end of each of said two oil cylinders, said inlets are each in communication with a corresponding one of said two oil pressure cylinders, two primary pistons inside said two oil cylinders, said primary pistons are driven by oil pressure from said two oil pressure cylinders to perform a downward movement, two secondary pistons inside said two oil cylinders, said secondary pistons are mounted below said two primary pistons and are driven downward by said two primary pistons, thus generating oil pressure and driving said braking movement of said two hydraulic brakes, a connecting plate fastened to upper ends of said two secondary pistons, so that upon a downward movement of one of said primary pistons, both of said secondary pistons are driven downward, simultaneously generating oil pressure.
