Description
Technical field
The utility model relates to a kind of motor vehicle complemental brake system, especially a kind of cooling device of eddy current retarder rotor.
Background technology
In general, the braking of current vortex retarder service vehicle makes driving more safe and reliable; And to make main brake be durable in use; But for the retarder with an inducing rotor, rotor assembly has tangible temperature rise at work, thereby influences the braking effect that current vortex rises slowly.Known different system is used for the heat radiation of rotor, for example through with the joining fan of rotor, described fan produces air-flow, the heat that dissipates with the discharging rotor.
For fan, can produce noise, and volume is very big, thereby strengthens the weight of retarder, in addition, these fans also can consume a lot of energy.
And; Because temperature of rotor very high (meeting is at 500 ℃-750 ℃ usually) after current vortex retarder works long hours during lower long slope; So the vehicle behind the lower long slope can not stop immediately, the stretch journey of need going makes rotor continue to keep rotating to think that rotor provides radiating airflow.So traditional current vortex retarder has restricted the flexibility of vehicle '.
Summary of the invention
(1) technical problem
The technical problem that the utility model will solve is through rotor being applied the cooling effect that the external refrigeration medium improves eddy current retarder rotor.The thin water smoke that the utility model adopts fine water fog generator to produce.
(2) technical scheme
In order to be implemented in above-mentioned purpose, the utility model proposes a kind of eddy current retarder rotor cooling device, comprising: a rotor, described rotor splice in one, and it has an axis, and drive described rotor rotation; One stator, and/or a housing its have a coil, described stator around or around described rotor, and the fan that produces air-flow.On described stator, fix the mist-generating nozzle that at least one aims at ring in the said rotor outside, and described mist-generating nozzle is communicated with the pressure water bottle through conduit and electromagnetically operated valve.
Described pressure water bottle front end connects an air compressor, for the pressure water bottle provides pressure.Described electromagnetically operated valve is by the controller control switch.
The temperature of rotor transfer of data of one temperature of rotor sensor acquisition is installed on said stator gives described controller, as the basis for estimation of switch electromagnetic valve.
(3) technique effect
The beneficial effect of the utility model is the cooling effectiveness that has improved eddy current retarder rotor, has improved the fail safe of vehicle ', and has solved the drawback that original current vortex retarder can not stop behind lower long slope immediately, has improved the flexibility of vehicle '.
