Description
Technical field the present invention relates to automobile-used electric braking method and device, particularly relates to slow method of the current vortex that is used for automobile braking system and retarder.
Background technology is along with the high speed development of auto-industry, and current vortex retarder has obtained utilization widely at automotive field.The principle of work of current vortex retarder roughly is such: the automobile in the enforcement needs glancing impact, and control circuit is according to the instruction that obtains, for each excitation winding of stator provides corresponding exciting current.Each the excitation winding assembly that is filled with iron core produces strong magnetic field, rotor metal flat that its magnetic line of force is rotated rapidly or cambered surface cutting, thereby generate current vortex at described metal covering internal induction, described stator and rotor are satisfied strong adsorption, produce lock torque, automobile kinetic energy is then because of changing the dissipation of generating heat of powerful current vortex in rotor.
The installation form of electric eddy current rail brake for vehicle mainly contains three kinds at present, is mounted in respectively in the middle of change speed gear box, back axle or the transmission shaft, and the common feature of these three kinds of installations is that the center of retarder promptly is the center of installation place transmission shaft.And must guarantee the minimum terrain clearance of car chassis also must guarantee this height after retarder is installed that this just requires the radial dimension of retarder as far as possible little during automobile design.In addition, the a lot of automobiles of China are not installed retarder before dispatching from the factory, because original design do not consider retarder will be installed, the locational space that retarder is installed in the car chassis is less, and this requires to reduce the volume of retarder equally under the identical situation of B.P..And existing automobile-used eddy current retarder mainly contains biplane rotator type and single rotor formula, but they have in limited time at installing space because of structure is compact inadequately, radial dimension is too big, and the retarder B.P. is too little.
The summary of the invention the technical problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of compact conformation, has the electric eddy current rail brake for vehicle of as far as possible little radial dimension under the identical situation of B.P..
The present invention solve the technical problem can be by realizing by the following technical solutions:
Propose a kind of current vortex retarder construction method that is used for self-propelled vehicle, comprise step:
1. the excitation winding assembly is set, sets up the work magnetic flux;
2. the thin-wall metal member rotor that links and rotate thereupon with described motor drive system or axletree is set, makes described work magnetic flux pass through the thin-walled of this hard ware and perpendicular to this thin-wall sense of motion;
3. arrange described excitation winding assembly, the feasible work magnetic flux that is produced by this excitation winding assembly is along the thin-walled that passes through described hard ware perpendicular to the direction of axletree;
4. be uncovered double cylinder-shaped rotor with described thin-wall metal member designs with same axis, one covers on another outside, the two has same bottom, follow the axletree rotation with same cireular frequency, each excitation winding is arranged in the annulus between described two cylinders, the axis normal of described winding and interior iron core thereof is in the axis of described two cylinders, and each winding and iron core thereof are fixed on the under-carriage by auxiliary part.
The present invention solve the technical problem can also be by realizing by the following technical solutions:
Design, a kind of current vortex retarder that is used for self-propelled vehicle of manufacturing, comprise the thin-wall metal member rotor that is fixed on each excitation winding on the under-carriage and interior iron core thereof and links and rotate thereupon by auxiliary part with described motor drive system or axletree, described rotor is have same axis uncovered double cylinder-shaped, one covers on another outside, the two has same bottom, moderate distance setting in described each winding and the iron core annulus between two cylinders of described rotor, the axis normal of each winding and interior iron core thereof is in the axis of described rotor.
Compare with prior art, technique effect of the present invention is:
1. compact conformation, volume is little, and the retarder inner space is fully utilized, and has reduced 15% than plane formula retarder volume under the situation that produces same magnetic field.Particularly the radial dimension of retarder reduces, and can guarantee that like this terrain clearance after retarder is installed greater than the minimum terrain clearance of automobile, fully guarantees the work safety of vehicle operational safety and retarder self.
2. the enclosed construction of two cylindrical rotors does not have foreign material and enters retarder inside and cause the retarder wearing and tearing when making retarder work, actv. has been protected the driving surface of retarder.
3. install simple.Because rotor is as a whole, just can finish the installation of retarder by disposable installation.And retarder stator and gap between rotor just can guarantee by machinework, can not exist owing to installation error does not guarantee stator and gap between rotor.In addition, because the radial dimension of retarder reduced, also help the installation of stator and fixing.
