Abstract
An electric vehicle motor belonging to the technical field of motor manufacturing comprises a shell (2) with an external rotor (1) and a magnetic steel (5), a stator iron core (4) arranged in the shell and provided with a fixed shaft(1) and a drum brake seat (8) which is arranged at an end surface of the shell and provided with a disassembly threaded hole (12). The drum brake seat and the shell are arranged in a divided structure and are fixedly connected through a screw (7). The utility model is reasonable in design by adopting a divided structure of the drum brake, the external rotor and the shell, broadens the material-choice ranges of the drum brake seat, and overcomes the defect that the drum brake seat might be heated to be deformed because of the integral material-limitation with the integral structure in prior art. The utility model can ensure the working efficiency of the drum brake seat which rotates together with the external rotor and the shell and further realize the rapid and effective braking. The utility model can be matched with various types of electric vehicles, especially suitable for cooperative use with the motor vehicles such as electric motorcycles and electric automobiles which have stricter requirements to the driving speed, thus improving the using performance and prolonging the service life of the integral motor.
Description
Technical field
The utility model relates to a kind of motor of electric motor car, belongs to the motor manufacturing technology field.
Background technology
Along with the raising of people's living standard and the requirements at the higher level that environmental protection is proposed, motor vehicles such as Moped Scooter, electric bicycle, battery-operated motor cycle, electric automobile arise at the historic moment.Its primary structure is that motor is directly installed in the electric vehicle hub, and electric motor car is implemented to drive and braking.
The housing of band external rotor and the drum of the braking usefulness seat of stopping is a monolithic construction on the existing motor of electric motor car, adopt the casting of 10# cast-steel integral to form, by the drum stop with the drum stop the seat cooperate the formation brake gear, though can implement braking to electric motor car preferably, but since be subjected to the used 10# cast steel material of external rotor and with the restriction of the bulging monolithic construction between the seat of stopping, make the coefficient of friction that rouses the seat of stopping lower, influenced braking ability, at electric motor car battery-operated motor cycle particularly, when electric automobile travels at a relatively high speed, rouse the easy generation heating of the seat of stopping and be out of shape, be difficult to realize fast and effeciently braking.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively realize fast braking, can improve the motor of electric motor car in electric efficiency and useful life again.
The utility model is a motor of electric motor car, comprise the housing of being with external rotor, place the stator core of band fixed axis in the housing, place the drum of the housing end face seat of stopping, it is characterized in that the described drum seat of stopping is a split-type structural with housing, drum is stopped and is fastenedly connected with screw between the seat and the end face of housing.During use, stop at drum and to install drum in the seat and stop, then with integral installation on the wheel hub of electric motor car, the driving that promptly can be used for electric motor car is travelled or braking brake.
Described drum is stopped and also can be provided with the dismounting screw on the seat.Described drum is stopped and also can be provided with a drum inserts of stopping on the inwall of seat.
The inwall of described external rotor and stator core also can be bonded with magnet steel on the corresponding position.
Described motor of electric motor car can be brshless DC motor.
Described drum stop the seat material can be aluminium alloy or iron casting.The stop material of an inserts of described drum can be iron casting.
The utility model adopts split type version with rousing stop seat and external rotor and housing, reasonable in design, widened the material range of choice that drum is stopped seat, the stop defective of seat heating distortion of the contingent drum that overcome monolithic construction of the prior art owing to be subjected to the restriction of integral material.And the drum seat of stopping closely is connected by screw with electric machine casing, can guarantee the drum operating efficiency of seat when turning round with external rotor and housing of stopping, and can stop at drum again the drum seat of stopping is done the time spent, realizes fast and effeciently braking.The utility model can with the supporting use of various types of electric motor cars, be particularly useful for the supporting use of the electric motor vehicle that travel speed had higher requirements with battery-operated motor cycle, electric automobile etc., serviceability and the useful life that can effectively improve complete machine.
Description of drawings
Fig. 1 is an overall structure cutaway view of the present utility model;
Fig. 2 is that A shown in Figure 1 is to structural representation;
Fig. 3 installs the structure cutaway view that rouses after stopping for the utility model.
Among the figure: 1 is external rotor, and 2 is electric machine casing, and 3 is the motor lead-out wire, and 4 is stator core, and 5 is magnet steel, and 6 is the screw packing ring, and 7 is screw, and 8 for rousing the seat of stopping, and 9 for rousing an inserts of stopping, and 10 is that drum is stopped, and 11 is fixed axis, and 12 is the dismounting screw.
Embodiment
The utility model mainly by the housing 2 of band external rotor 1, place band fixed axis 11 and motor lead-out wire 3 in the housing 2 stator core 4, place the drum of housing 2 end face bands dismounting screw 12 stop seat 8, be bonded on the inwall of external rotor 1 with stator core 4 corresponding magnet steel 5 etc. and constitute, rouse the seat 8 of stopping and be split-type structural with housing 2, drum is stopped, and the screw 7 with belt washer 6 is fastenedly connected between seat 8 and the end face of housing 2, and drum is stopped also to be provided with on 8 the inwall and roused the inserts 9 of stopping.The common 10# cast-steel integral casting of the material selection of external rotor 1 and housing 2 forms, and rouses the material selection iron casting of stop seat 8 and inserts 9.
During use, install drum in 8 and stop 10 at the drum seat of stopping, then with integral installation on the wheel hub of electric motor car, can stop by drum and 10 stop with drum and cooperating of seat 8 to constitute brake gear, the driving that is used for electric motor car is travelled or braking brake, realizes fast and effeciently braking.
