The invention belongs to the field of automobile braking
energy recycling, and particularly relates to a braking power generation
mechanism based on hydraulic transmission. The braking power generation
mechanism based on hydraulic transmission comprises a
brake disk, a
brake disk protrusion,
brake pad supports, hydraulic columns, a
hydraulic cylinder, a
piston, a
hydraulic motor and a power generator. The
brake pad supports are installed on a brake mechanism support. When the brake disk rotates, at the early stage of the braking process, a
brake pad gets close to the brake disk gradually, an ejecting block firstly makes contact with the protrusion and is matched with the protrusion, the ejecting block linearly reciprocates in the direction of a cylindrical guide rail, the
piston is driven to reciprocate through cooperation so that hydraulic
oil can be driven to flow in the
hydraulic motor in a reciprocating manner, and therefore the power generator can be driven to generate power; and at the later stage of braking, the
brake pad starts to make contact with the brake disk, large
friction force is generated, and wheels are braked forcibly. Due to the cooperation of the ejecting block and the protrusion, braking energy is converted into reciprocating movement, and therefore the hydraulic oil is driven to flow in the reciprocating manner, the power generator is driven to generate power, the braking energy is effectively utilized, and the energy saving effect of an automobile is improved.
