Abstract
The invention relates to a multifunctional brake disc of an electric vehicle, which mainly comprises a brake disc and is characterized in that the inner side of the circumference of the brake disc is provided with a plurality of noise reduction notches; the outer side of the circumference of the brake disc is provided with a plurality of heat dissipation lugs; recesses among the lugs are set into locking holes; and the locking holes are matched with a spring bolt. In the multifunctional brake disc of the electric vehicle, as the inner side of the circumference of the brake disc is provided with the notches so as to reduce noise when braking is performed, and the periphery of the brake disc is provided with the lugs, airflow is generated when the brake disc rotates to perform accelerated cooling on heat generated when the braking is performed, and moreover, the recesses among the heat dissipation lugs are used as the locking holes, thus, the multifunctional brake disc of the electric vehicle has a very simple structure, and not only is easy to manufacture, reduces the cost but also improves the braking performance.
Description
Technical field
The present invention relates to electric motor car servant brake brake disc, more specifically the locking hole that ability noise reduction, heat radiation are set of brake disc on every side.
Background technique
Purpose is the ZL200720043570.4 of notice of authorization openly; The electric motor car servant brake is made up of the radiating fin ring gear interference fit of brake disc collar wall and radiating fin with flange-cooled brake disc assembly; The annulus circle limit, outer ring and the radiating fin collar wall of radiating fin are gapped between the two, and the clearance groove bottom is clearance groove annulus bottom plane.
But because brake disc inner ring wall is done time spent friction and constantly produced heating receiving brake slipper, tending to produce cohesive body after the heating of brake slipper can't volatilize, and is easy to produce noise; Braking function promptly goes down, though the brake disc collar wall is provided with radiating fin, its effect is obvious inadequately; When running into follow-up lock valve, need open keyhole on the brake disc, its defective is more obvious; Can't be provided with, thereby can't extensively adopt.
Another kind of disclosed electric bicycle reaches electric bicycle and uses brake plate sleeve ZL200620073868.5 with brake disc assembly parts ZL200620073896.7, and these two kinds of structures are all at the arranged outside brake plate sleeve of brake disc; On brake plate sleeve, have lockhole, brake disc and brake plate sleeve welding are fixed as one, thereby the brake disc outer ring is constantly thickeied; Not only increase cost; Its thermal diffusivity is poorer, and makes very complicacy, has expended great deal of steel.
Also a kind of disclosed bicycle and electric motor car follow-up lock valve be with brake disc ZL200620125124.3 brake disc, is connected with the lock cover of one periphery being provided with of fuse-box, and lock puts the unlocking rod hole slot; This structure is more advanced than first three structure; But still rather complicated, and brake slipper produces heat, the very difficult elimination of the surperficial cohesive body of brake slipper after continuous action; Thereby the generation noise, and influence braking effect.
Summary of the invention
The multi-functional brake disc of a kind of electric motor car of the present invention is the hole that ability noise reduction heat radiation is set on the circumference of brake disc and has locking function; The present invention is achieved in that the inboard has shrinkage pool around brake disc, and shrinkage pool is several; The outer periphery of brake disc is provided with the projection of heat radiation; Number of slugs is provided with as required, and the distance that between projection and the projection needs is set is as locking hole, and locking hole and dead bolt are complementary.Structure of the present invention is very simple, not only easy to manufacture, and manufacture cost is very low, and effect is fairly obvious.
The inboard notch effect of brake disc during use: brake slipper and brake disc inside circumference produce friction when braking; Have some recesses because of the brake disc inboard when rubbing continuously; Brake slipper is rubbed from the continuous friction section of changing over is continuous in the brake disc inboard; Let produce to surpass the heat that friction material bears and be easy to leave, greatly reduce the friction frictional heat of brake slipper and brake disc, the reduction noise because of the brake slipper surface is heated.
During use; The projection effect that the brake disc outer periphery is provided with: when needs were braked, the friction when braking of brake slipper and brake disc inside circumference had produced heat; When electric motor car is accomplished continued to overtake a braking maneuver; Brake disc rotates because the effect of projection produces air-flow, and very fast brake disc is cooled off recovers braking effect thereby quickening reduces the temperature of brake disc.Though several recesses have been left in the brake disc inboard; Reduced the inboard rubbing contact area of brake slipper and brake disc; When also having increased in brake slipper and the brake disc side-friction force balance temperature of brake disc; Accelerated distributing of brake slipper surface heat energy, through finding that through test braking effect has had significant change.
The present invention is provided with some heat radiation projections from the brake disc outer circumference; Indentations distance between projection and the projection is arranged to locking hole and is mated with dead bolt, during use, as long as dead bolt gets into the recess locking hole between projection and the projection; Dead bolt will limit brake disc and rotate, and produce good locking effect.
Accompanying drawing 1 is brake disc structural representation of the present invention
Embodiment
The multi-functional brake disc of a kind of electric motor car is by brake disc 1; Have noise reduction shrinkage pool 3 on the brake disc inside circumference 2; The periphery 4 of brake disc 1 is provided with the projection 5 of heat radiation; Projection 5 and be concavity between the projection 5 of symmetry nearby, with the locking hole 6 that concavity setting and dead bolt (this figure does not annotate) are complementary, locking hole 6 and dead bolt (this figure does not annotate) are complementary.
During use; Shrinkage pool 3 effect is set in the inboard of brake disc 1: brake slipper (this figure does not annotate) and 2 frictions of brake disc 1 inside circumference are used continuously, because of brake disc 1 inboard 2 has some recesses 3, brake slipper (this figure does not annotate) and brake disc 1 will be in the brake disc inboard around the continuous section of becoming that rubs continue and rub; And cause that brake slipper (this figure does not annotate) surface produces heat and from recess 3, discharges; Increase the inboard frictional force of brake slipper and brake disc simultaneously, reduced friction noise, increased brake slipper life-span and braking effect greatly.
Effect two during use, the projection 5 that around the brake disc outside 4, is provided with are behind the fricative heat of brake slipper (this figure does not annotate), and during electric vehicle running, the projection of brake disc outer ring produces air-flow along with brake disc 1 rotation, accelerates the cooling of brake disc 1.The quickening cooling of brake disc 1 is the measure that well improves braking effect.
Effect three during use: the periphery 4 at brake disc 1 is provided with projection 5; Be indentations between projection 5 and the projection, indentations is provided with a locking hole 6 that is complementary with dead bolt (this figure does not annotate), as long as dead bolt gets into locking hole; Brake disc just can not rotate, and has played the effect of locking function.More than 3 inventions be a very big improvement to the brake disc of existing technology, brake disc 1 inboard has recess 3 and has played the continuous friction of the continuous friction section of becoming of brake slipper and brake disc inner ring, reduces the noise that brake disc heating back braking produces.Brake disc 1 arranged outside projection 5 rotates the rate of cooling of accelerating brake disc 1 at brake disc 1, improves working life; Be spill between projection 5 and the projection 5,, make locking hole 6 with the dead bolt coupling; Servant brake brake disc 1 locking function need not increase brake plate sleeve on brake disc 1; Not only reduce the braking cost, and structure is simpler, improves braking effect.
