Abstract
The utility model improves a plane reversing motor with a bush, an end cover and a carbon brush rack for an electric bicycle and a motorcycle, the utility model is characterized in that the end cover side of a motor at one side of a carbon brush is at least provided with a window which is closed by an additional cover board, and the carbon brush rack is in a composite structure with a movable cover. The utility model not only keeps the totally-enclosed characteristics of the motor, but also simplifies the replacement of the carbon brush, and does not need a professional, does not need to disconnect the end cover of the motor, and only need to loosen the sealing cover board of the window and a removable cover of the frame of the carbon brush to pull out the carbon brush, then a new carbon brush can be conveniently replaced, and the replacement is easy and convenient. Therefore, the utility model makes the carbon brush which has relative shorter replacing frequency replace completely by a consumer, has the advantages of simple and quick replacement, low working strength and a little replacing cost, and only needs to pay the expenses of the carbon brush, and furthermore the other parts of the motor are not damaged.
Description
Technical field
Utility model relates to a kind of brush motor, especially to electric bicycle and motorcycle with the plane brush motor that commutates, the improvement of end cap and carbon brush holder, it is easy that carbon brush for electric machine is changed.
Prior art
External rotor plane commutation low speed brush motor, because of having starting torque and moment of torsion is big, the efficient height, comprehensive good, thereby be widely used in electric bicycle, battery-operated motor cycle is used as power.Yet, electric bicycle, battery-operated motor cycle have low noise owing to requiring motor, therefore can only select soft carbon brush for use, and the resistance to wear of soft carbon brush is relatively low, so carbon brush is shorter relatively useful life, general electric bicycle motor carbon brush useful life is 2～three years, battery-operated motor cycle carbon brush for electric machine useful life, only about 1 year, it was higher relatively to cause carbon brush to change frequency thus.Because dustproof the grade needs, the whole full-closed structure that adopts of motor, carbon brush be by the built-in electric motor end cap inboard that is enclosed in, and its structure is as described in the Chinese patent 90207397,98213933,01233492.Change carbon brush like this and need dismantle end cap, the dismounting end cap not only needs the specialized maintenance personnel, and the end cap dismounting easily causes the damage to motor, as draw group end cap to cause motor to hold damage of bearings easily, and bicycle, motorcycle use in regular vibration environment, tighten screw loosening and come off for preventing end cap, usually be added with sealing glue at screw, though it is loosening that glue curing has effectively prevented trip bolt, but dismounting is made troubles to end cap on the contrary, cause trip bolt to damage during dismounting easily, serious meeting causes the damage of wheel hub.Secondly, existing carbon brush holder all adopts built-in fixed, and carbon brush is fixed in the carbon brush frame-saw, and carbon brush is changed need take carbon brush holder apart, also makes and changes difficulty.Therefore electric bicycle and motorcycle replacing carbon brush is a relatively pain in the neck, and it is big to change workload, the maintenance cost height, and can damage motor.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and it is easy to provide a kind of carbon brush to change, and need not dismantle the external rotor plane commutation brush motor of electric motor end cap.
The utility model purpose realizes that main the improvement is to have a window at least at carbon brush for electric machine one side capping, and sealed with adding cover plate, and changed carbon brush holder into the removable cover combining structure.Specifically, utility model external rotor plane commutation brush motor, the plane commutation board that comprises external rotor and servo-actuated, internal stator, the carbon brush holder of built-in carbon brush, the both sides closed end cap is characterized in that said carbon brush one side motor side capping has a window at least, said window adds cover closure, and said carbon brush holder is for there being the removable cover combining structure.
The said carbon brush holder of utility model is for there being the removable cover combining structure, main effect is by the comings and goings lid is set on the brush holder frame, can realize not dismantling brush holder by opening removable cover with regard to replaceable carbon brush, concrete structure can have multiple, cover as axial thread, axial side is inserted lid, and hinge or socket fasten lid etc.Wherein simple with the axial thread lid especially.
Utility model is owing to have replacing carbon brush window at carbon brush for electric machine one side capping, and the window place is provided with the movable sealing cover plate, and changes fixed sealing enclosed carbon brush holder into the removable cover combining structure.Not only kept the totally-enclosed characteristic of motor, and simplified the replacing of carbon brush, need not the professional, need not to take apart electric motor end cap, as long as unclamp the window seal cover board, and carbon brush framework removable cover, carbon brush just pulled out to be convenient for changing new carbon brush.Change frequency carbon brush replacing relatively thereby make, can be finished by consumer oneself fully, replacing is simple, quick, and working strength is low, and renewal cost is few, only need pay the carbon brush expense, and can not damage the motor miscellaneous part.Having overcome prior art replacing carbon brush needs the professional, and time-consuming, maintenance cost is big, and the shortcoming of fragile motor.
Below in conjunction with a specific embodiment, further specify the utility model structure, but the embodiment structure not the qualification to utility model.
Description of drawings
Accompanying drawing is a utility model example structure schematic diagram.
Embodiment
Embodiment: referring to accompanying drawing, commutation brush motor in utility model external rotor plane has the plane commutation board 9 of external rotor 4 and servo-actuated, by the internal stator 5 that magnet steel and steel-casting are formed, and the carbon brush holder 7 of built-in carbon brush 8, compositions such as both sides closed end cap 1,10.1 of carbon brush side electric motor end cap is gone up the carbon brush replacing window 11 that symmetry has two band sealed step 12, and window is by outer cover plate 2, sealing ring 3 sealings, and carbon brush holder has brush holder frame 7 and 6 combinations of spiral removable cover.
The electric motor end cap window can also be single or multiple; Brush holder removable cover form can also have various ways, and these all belong to the utility model protection scope.
Claims (5)
