Description
One, technical field:
The present invention relates to a kind of automobile brake technical field, particularly relate to a kind of automobile disk type electromagnetic damping brake.
Two, background technology:
The brake system of automobile mainly is divided into three major types on the market at present: the one, and mechanical brake system, the 2nd, hydraulic brake system, the 3rd, pneumatic brake system.There is total weak point in these three kinds of brake system: 1, the friction that produces in the process of braking can make the temperature of brake disc rise, and braking efficiency is reduced, thereby can cause the accident because of the decline of braking force.2, the frequent use of drg can cause the wearing and tearing of drg itself, can be because of changing a large amount of money of brake system consumption.3, it is serious that the effect of brake system is subjected to the influence of environment, can cause the malfunctioning of brake because of rugged environment.4, need the mechanical device and the pipeline of complicated layout on the car, this brings a lot of troubles can for design and assembling, and car accident malfunctioning because of machinery and that pipe leakage caused can occur.
Three, summary of the invention:
Purpose of the present invention is exactly the above-mentioned defective that exists at prior art, provides a kind of electromagnetic resistance that utilizes frictionless electromagnetic eddy damping brake gear to be produced to realize the automobile disk type electromagnetic damping brake of the braking of automobile.
Its technical scheme is: mainly be made up of conduction brake disc, stator coil left socle and stator coil right support, the a plurality of axial pass-through holes of distribution on the end face of stator coil left socle and stator coil right support, magnetizer that is twining coil of each hole internal fixation; Described conduction brake disc is discoid entity by the profile of magnetic conductive metal manufacturing, and the in-to-in hole is a stepped appearance, and fixes by stepped appearance reaction plate and center rotating shaft, and described center rotating shaft is by the wheel hub mortise of disk and motor tire; Firm the connecting as one of wheel hub of conduction brake disc, center rotating shaft, stepped appearance reaction plate, disk and motor tire; The conduction brake disc is fixed by bolt of rear end plate and stepped appearance reaction plate, the stepped appearance reaction plate is fixed by the mode and the center rotating shaft of interference fit and welding, the center rotating shaft right-hand member is fixed a disk that has a bolt of rear end plate by interference fit, welding manner, and disk diameter is slightly less than the diameter of stepped appearance reaction plate, and disk is by terminal wheel hub mortise along circumference well-distributed bolt of rear end plate and motor tire.
Further preferred scheme is that the gap between conduction brake disc and the left and right support of stator coil is 1.0～2.0mm.
In addition, a uniform 4-8 axial pass-through holes on the end face of stator coil left socle and stator coil right support.
The parameter of above-mentioned coil is: line footpath: Φ 0.2～0.8mm; Coil diameter: Φ 30～40mm; Coil turn: 400～1500 circles, certainly, coil number, the line directly size because of the vehicle volume and weight are different, and along with the increase of vehicle volume and weight, all can there be corresponding increase in coil number and line footpath.
Work principle is: thus when rotating in magnetic field, the conducting metal dish can stop because of producing stronger vortex flow sport, the disk type metal rotor is housed in brake device for car, when the excitation coil of stator pack has when passing through than heavy current, the magnetic field of its generation can stop the rotor rotation of cutting magnetic line, thereby produces the braking that lock torque is realized automobile.
The invention has the beneficial effects as follows: automobile does not have rigid friction braking, has eliminated wearing and tearing, and braking simultaneously is stable, is easy to be subjected to vehicle-mounted computer to control, and helps the driving safety of automobile under most of environment.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
