Abstract
The utility model relates to an electromagnetic brake for an electric vehicle, in particular to a special brake component for the electric vehicle. The utility model adopts the technical scheme as follows: a brake block and an actuating plate are arranged on a bottom plate in sequence; a fixed seat is fastened with the bottom plate; a spring guide pillar is arranged on the fixed seat; a spring is sleeved on the spring guide pillar; the fixed seat is connected with the bottom plate through a clearance tube; a coil is arranged on the fixed seat; and a connector is fixed on the axis of a rotor. The utility model is characterized in that a penetration aperture is formed at the outer wall edge of the connector, a rubber strip is arranged in the aperture, the periphery of the rubber strip slightly protrudes out of the outer wall of the connector, and the connector has the same height as the rubber strip. The utility model has the following advantages: the structure is simple, compact and reasonable; and when the brake is electrified in the non-braking state, the connector drives the brake block to rotate, and meanwhile the rubber strip generates the buffer action between the connector and the brake block and absorbs the most vibrations, thereby solving the problem that abnormal sounds generated in low or high speed rotations causes rotation noises.
Description
Technical field
The utility model relates to a kind of electric vehicles electromagnetic brake device, the specifically special-purpose brake part of elec. vehicle.
Background technology
In prior art, electric vehicles electromagnetic brake device mainly is made up of permanent seat, spring guide pillar, spring, coil, start plate, brake facing, base plate and adaptor union etc.
When being energized to the coil of permanent seat, produce magnetic field by the winding of coil and the wall thickness of permanent seat, the start plate is upwards taken up, just produce small gap, this minim gap between brake facing and the start plate this moment; Can make brake facing be threaded into connector in the endoporus and drive and rotate, just become no braking state this moment.
Above-mentioned electromagnetic brake device is at no braking state, when connector drives the brake facing rotation, gapped between the inner hole wall because of connector and brake facing, cause when rotation to produce the unusual sound, cause the Rotation Noise problem because of the inertia relation makes the brake facing inner hole wall clash into connector continuously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of electric vehicles electromagnetic brake device, when switching on afterwards in no braking state, connector drives the brake facing rotation, the two between produce buffer action because of rubber strip this moment, and absorb most vibrations, and when low speed or high speed revolution, all can not produce the unusual sound, cause the Rotation Noise problem.
The technical scheme that provides according to the utility model, electric vehicles electromagnetic brake device adopts and be disposed with brake facing and start plate on base plate, permanent seat and base plate are fastening, spring guide pillar is arranged on the permanent seat, spring housing is contained on the spring guide pillar, be connected by gas tube between permanent seat and the base plate, coil is set on permanent seat, steel ball is arranged on the permanent seat, adaptor union is fixed on the axle center of rotor, feature is that the outer wall limit of described connector is provided with and runs through aperture, and the rubber strip of packing in aperture.
The periphery of described rubber strip protrudes in the outer wall of connector a little.
The height of described connector equates with the height of rubber strip.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; When energising back during in no braking state, connector drives the brake facing rotation, produces buffer action because of rubber strip between the two at this moment, and absorbs most vibrations, all can not produce the unusual sound when low speed or high speed revolution, and cause the Rotation Noise problem.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model connector structural representation.
The specific embodiment
Following the utility model embodiment in will be in conjunction with the accompanying drawings is further described: as Fig. 1～shown in Figure 2, comprise permanent seat 1, handle 2, spring guide pillar 3, spring 4, coil 5, start plate 6, brake facing 7, base plate 8, steel ball 9, screw 10, screw 11, gas tube 12, adaptor union 13 and rubber strip 14 etc.
The utility model adopts and be disposed with brake facing 7 and start plate 6 on base plate 8, permanent seat 1 adopts screw 11 fastening with base plate 8, spring guide pillar 3 is arranged on the base 1, spring 4 is sleeved on the spring guide pillar 3, be connected by gas tube 12 between permanent seat 1 and the base plate 8, coil 5 is set on permanent seat 1, steel ball 9 is arranged on the permanent seat 1, handle 2 adopts screw 10 to be fixed on the guide pillar 3, adaptor union 13 is fixed on the axle center of rotor, the outer wall limit of described connector 13 is provided with runs through aperture, and the rubber strip 14 of packing in aperture, and the height of described connector 3 equates with the height of rubber strip 14.The periphery of rubber strip 14 protrudes in the outer wall of connector 13 a little.
When the electromagnetic brake device at no braking state, when connector drives the brake facing rotation, because being provided with, the outer wall limit of connector 13 runs through aperture, and the rubber strip 14 of in aperture, packing into, the outer wall of the outstanding a little dried connector 13 of the periphery of rubber strip 14, connector 13 penetrates in the endoporus of brake facing 7, gap to each other can be filled up.Because of inertia concerns that the brake facing inner hole wall clashes into connector continuously and can not produce the unusual sound, more can not cause the Rotation Noise problem during rotation.
When supply disconnecton, the magnetic field force that the application force of spring 4 is produced greater than coil 5, at this moment, spring 5 drives spring guide pillar 3 start plate 6 is promoted downwards, brake facing 7 is clamped simultaneously by start plate 6 and base plate 8, and the friction drag that utilizes brake facing 7 stops the rotation brake facing 7, simultaneously the connector 13 that penetrates endoporus stopped the rotation, and just becomes braking state this moment.
