Description
Technical field
The present invention relates to a kind of vehicle retarder, relate in particular to a kind of current vortex retarder that electromagnetic type current vortex retarder and permanent-magnet type eddy current retarder technology are carried out combination.
Background technology
At present, in the retarder technical field, the electromagnetic type current vortex retarder is extensively used, and the permanent-magnet type eddy current retarder is promoted the stage.
The electromagnetic type current vortex retarder has obtained particularly driver's approval of users, its contactless mode of braking makes driving easier, drive more comfortablely, can bear the most brake loads in the running car, effectively protected wheel drag; Rotating torque directly acts on the power transmission shaft, thoroughly stops the brake side-slipping phenomenon; Adopt electric current directly to drive, do not have intermediate link, be quick on the draw, the operation response time only has 40 milliseconds; It is braking system independently, has improved the diversification of braking, effectively alleviates the danger that the traditional braking sudden failure forms.
The major advantage of electromagnetic type current vortex retarder and deficiency
Most widely used on commercial vehicle at present is the electromagnetic type current vortex retarder, and its major advantage has:
(1) do not have wearing and tearing: when the retarder stator did not power up, rotor can freely rotate; In case power up and promptly produce the jogging effect.The commentaries on classics power of the power drive system of vehicle can not produce under the friction situation slowly to descend, and therefore can not wear and tear.
(2) reduce maintenance cost: often use retarder can more effectively reduce the maintenance of brake.The test that France, Germany, the U.S. and other countries successively carry out has confirmed the maintenance effect of retarder to brake.It can reach 4 to 7 times according to the life-span of different behaviour in service prolongation brake pads.
(3) improve average speed: a test of carrying out in Germany confirms, one was on average travelled after 800 kilometers truck fleet uses current vortex retarder through every day on the hill path of being everlasting, and travel speed increases by 10%, thereby can improve the efficiency of operation of fleet better.
(4) improve the fail safe and the comfort of driving: facts have proved that current vortex retarder also can improve the fail safe and the comfort of driving, reduce fatigue, increase work efficiency.Thereby strengthen service and shipping efficient.Drive more smooth and easyly, minimizing is brought to a halt, and makes rolling stock and rolling stock accessories can both bring into play best effectiveness.
The electromagnetic type current vortex retarder still exists some shortcomings:
(1) quality is heavier, has increased the kerb weight of car load after the entrucking.
(2) power consumption need consume a large amount of electric energy during the retarder braking greatly, need change or increase powerful generator when retarder is installed, and generally needs the above generator ability operate as normal of 150A at least, has increased energy resource consumption.
(3) heat fade is big, and retarder works long hours, and can cause coil heating, and resistance increases, and causes retarder moment to descend.
The permanent-magnet type eddy current retarder still is in the preliminary promotion and application stage at home, has only small number of users using.
The major advantage of permanent-magnet type eddy current retarder and deficiency
The advantage of permanent-magnet type eddy current retarder has:
(1) no energy consumption.Do not need to consume a large amount of electric energy during retarder work, the magnetic energy that utilizes permanent magnet to have carries out work, does not need to increase the power of generator.
(2) moment good stability.It is not overheated to use continuously, and permanent magnet itself does not generate heat at work, can keep stablizing and lasting braking force.
(3) volume is little, in light weight and have non-maintaining characteristics.
The shortcoming of permanent-magnet type eddy current retarder has:
(1) moment is little.The remanent magnetism problem of permanent-magnet type eddy current retarder is difficult to solve, and makes braking moment be difficult to develop to big direction.The permanent-magnet type eddy current retarder of present domestic maximum moment has only 1000Nm, the demand of incompatibility Hyundai Motor.
(2) still there is very big plugging moment in non operating state.Be because the demagnetization of retarder is unclean, cause a large amount of energy wastes, increased the automobile use cost, be not suitable for current energy-conservation theory.
(3) controls reaction speed is slower.Permanent-magnet speed buffer work is to rely on air cylinder driven.The thrust of cylinder is bigger, and air pressure is generally less than 1MPa, and required tolerance is bigger.Cause permanent-magnet speed buffer slow in reacting.
(4) can not control the operation torque of retarder.Domestic once had the document of related fields to mention the grading control of permanent-magnet speed buffer, but up to the present also really do not put on market.
Summary of the invention
The present invention is directed to the problem that above two kinds of retarders exist, in conjunction with they advantages separately, provide a kind of moment that had both had an existing electromagnetic type current vortex retarder big, reaction speed is fast, have energy-conservation, in light weight, the Heat stability is good of permanent-magnet type eddy current retarder, the characteristics that maintenance is few again, thus have energy-conservation, moment of torsion is big, in light weight, reaction speed fast, compact conformation, safety, the use birthday noodle are long, the low speed stopping power is good, a kind of current vortex retarder that can realize grading control and stepless speed regulation.
Technical scheme of the present invention is: comprise fixed mount, rotor, terminal box, it also comprises some permanent magnets, some electromagnetic blocks and electromagnetic block controller; Some permanent magnets and electromagnetic block interval cloth successively are listed on the same circumference of fixed mount; Some permanent magnets homopolarities are to laying, and some electromagnetic blocks and the permanent magnets utmost point are to opposite laying, and electromagnetic block connects controller.
