Embodiment Construction
[0017] Such as figure 1 , the original automotive hydraulic retarder device includes an input shaft 1, a moving wheel 2 and a fixed wheel 3, the input shaft 1 drives the driving wheel 2 to rotate, and the moving wheel 2 drives the retarder oil to rotate and impact the fixed wheel 3. The oil inlet pipe 4 of the fixed wheel and the oil outlet pipe 31 of the moving wheel are respectively connected to the retarder oil tank 13 to form the return flow of the retarder oil.
[0018] In the present invention, the oil outlet of the oil outlet pipe 31 of the moving wheel is improved, and a part of the oil outlet pipe 31 of the moving wheel is placed in the evaporator 5 between the moving wheel 2 and the retarder oil tank 13, so that the retarder oil flows from the oil outlet pipe 31 of the retarder. Pass through the evaporator 5 before returning to the retarder oil tank 13. The pipeline 6 with chlorofluorocarbons is a closed loop structure and passes through the evaporator 5, a turbine ...

The invention discloses a power generation method and a device of an automotive hydro-dynamic retarder. Partial driving wheel oil outlet pipe between a driving wheel and a retarder oil box is arranged inside an evaporator, a pipeline with Freon is of a closed loop structure and passes through the evaporator, a pipeline which is arranged outside the evaporator is provided with a turbine unit, and the turbine unit is coaxially connected with a permanent magnet generator; an electromagnetic valve and an electromagnetic valve core which are connected with a retarder oil box upper port are connected with a controller through a control wire. The hydro-dynamic retarder adopts the evaporator to evaporate the heat absorbed by the Freon in the pipeline from the retarder oil, the produced air pressure pushes blades inside the turbine unit to rotate so as to drive the permanent magnet of the permanent magnet generator and a rotator magnetic yoke to rotate together, so a stator coil of the permanent magnet generator produces three-phase current under the effect of an alternating magnetic field. An electromagnetic fan radiates the heat of freezing agent and consumes the dynamic energy of the input shaft when in work so as to further improve the retarding effect. The power generation method and device effectively realize the recycling and regeneration of the dynamic energy of the automotive and realizes the energy conservation.
Description
technical field [0001] The invention relates to an automobile retarder and a vehicle-mounted power generation system, in particular to a power generation method and device for a hydraulic retarder. Background technique [0002] Hydraulic retarder is an auxiliary braking device used in the braking system of transport vehicles. It is a rotary damping device. It uses its moving wheel to drive the retarder oil to rotate and impact the fixed wheel. At this time, the fixed wheel will also pass through the retarder. The retarder oil produces a reaction force acting on the moving wheel, thereby hindering the rotation of the moving wheel, converting the kinetic energy of the vehicle into the heat energy of the retarder oil, and reducing the speed of the vehicle. [0003] Due to the frequent braking of the car during driving, the retarder oil is always in a high temperature state, and the retarder oil at high temperature will affect the retarding effect to a certain extent. Therefore,...
