Abstract
An eddy current brake comprises a front rotor disc and a rear rotor disc, which are connected to a transmission shaft sequentially, a stator is arranged between the front rotor disc and the rear rotor disc, fixed on a chassis, and provided with a coil winding, 10 coils in the coil winding are alternative in polarity and evenly distributed on the stator in a circular array manner. According to the novel eddy current brake, the traditional buffer design idea is changed, the eight-coil structure of a conventional brake is adjusted to a ten-coil structure, the circle formed by the coils is enlarged, the space occupancy of the coils of the brake is increased, and the bore of the brake is enlarged.
Description
Technical field
The utility model relates to a kind of novel current vortex retarder.
Background technology
Current vortex retarder is a kind of auxiliary brake device for automobile, and this device is installed between automobile drive axle and the gearbox, realizes contactless braking by electromagnetic induction principle, is a necessary complement of braking system, but can not replaces primary brake system.Current vortex retarder generally is made up of stator, rotor and fixed support.During retarder work, energising produces magnetic field in the stator coil, and rotor rotates with power transmission shaft.The magnetic line of force that the rotor cutting stator produces, thereby at the Vorticose induced current of the inner generation of rotor disk.Like this, stator will apply an electromagnetic force that hinders the rotor rotation to rotor, thereby produces braking moment.Simultaneously, eddy current has the rotor disk internal circulation of certain resistance, because the thermal effect of resistance can be converted into heat energy to electric energy, like this, the kinetic energy of vehicle ' just finally is converted into heat energy by electromagnetic induction and resistance heating and distributes.When automobile normal running, although rotor is with the power transmission shaft high speed rotating, but owing to coil no power this moment, iron core does not have magnetic field, so do not produce braking moment, if the logical exciting curent of coil, several iron cores just produce several magnetic fields, part magnetic flux by iron core increases, and the part magnetic flux that leaves iron core reduces, and produces current vortex in the rotor disk thereby make, the rotor disk of current-carrying is subjected to the effect of power in magnetic field, its action direction is opposite with the direction of rotation of rotor disk, hinders the rotation of rotor disk, thereby makes current vortex retarder produce braking moment.The braking moment that current vortex retarder produced can be regulated by the exciting curent control device, and big more by the exciting curent of coil, magnetic field is strong more, and braking moment is just big more.
Passenger vehicle on the Chinese market below 9 meters has following characteristics to the requirement of current vortex retarder: total amount requires gently, the operating current requirement is little, volume requirement is little, and the arrangement of bores of retarder requirement simultaneously is big, can satisfy different application demands like this.
The utility model content
In order to address the above problem, the utility model provides a kind of novel current vortex retarder.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
A kind of novel current vortex retarder, rotor disk and back rotor disk before comprising, preceding rotor disk is connected with power transmission shaft respectively with the back rotor disk, be provided with stator between preceding rotor disk and the back rotor disk, stator is fixed on the chassis, and stator is provided with coil windings, and the polarity of each coil is positive and negative in the coil windings is arranged alternately, described coil is provided with 10, evenly arranges by circular array on stator.
The polarity of adjacent two coils is set on the contrary on the stator, when coil is connected direct current, each coil produces magnetic field, rotor assembly is with system of vehicle transmission part high speed rotating cutting magnetic line, produce opposing torque, the resistance that produces passes through on differential mechanism mean allocation to two trailing wheel, thereby reaches the purpose that makes vehicle deceleration.
The beneficial effects of the utility model are, this novel current vortex retarder has changed traditional retarder design concept, 8 loop constructions of conventional retarder are adjusted into 10, the layout circle of coil can increase like this, and can increase the space occupancy of retarder coil, guarantee that simultaneously the endoporus of retarder inside strengthens.
