Abstract
The utility model relates to a driving motor for an electric bus. The driving motor for the electric bus is characterized in that a cantilever is arranged on a motor casing; mounting holes are formed on the cantilever; the output shaft of a motor is connected with a coupler; connection holes connected with a flange plate are formed on the coupler; a first insulation pad and a second insulation pad are arranged on the upper end surface and the lower end surface of each mounting hole on the cantilever respectively; an insulation pad plate is arranged between the coupler and the flange plate; and an insulation sleeve is arranged in each connection hole on the coupler. By adopting the technical scheme, the driving motor has the advantage that insulation pieces are arranged at the parts, so that insulation between induction electromotive force generated when a motor controller of the electric bus drives the motor and the bus body can be ensured, then the induction electromotive force is prevented from conducting to the bus body, and safety and stability of the electric bus can be ensured.
Description
Technical field
The utility model relates to a kind of insulation system of drive motors, relates to a kind of insulation system that is used for electronic big bus drive motors specifically.
Background technology
Electric automobile receives the extensive support that national governments showed great attention to and received society as the new forms of energy vehicles; Along with the minimizing with reserves that grows to even greater heights of petroleum gas price; The continuous attenuating with manufacturing cost of reaching its maturity of electric vehicle engineering can be predicted electric automobile and will be used widely.In order to reduce the pollution discharge capacity of city automobile, realize the development strategy of new-energy automobile, the electronic big bus of zero discharge just becomes the main force of new-energy automobile in the city, and the drive system that adopts induction machine to form has very high cost performance and reliability.In the process of using electric machine controller to drive,, but, therefore can on the shell of motor, induce very high electromotive force as the induction machine that drives usefulness on the electronic big bus by the square wave that pulse is formed owing to the winding through motor is not sinusoidal wave.Because this induction machine can not the same reliable ground connection with common electric machine, so must prevent that induced electromotive force can not conduct on the car body here.
The utility model content
The purpose of the utility model is to provide the insulation system of a kind of electronic big bus with drive motors, this motor can and car body between keep insulation.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme: a kind of electronic big bus is used drive motors, and motor housing is provided with cantilever; Cantilever is provided with installing hole; The output shaft of motor links to each other with shaft coupling, and shaft coupling is provided with the connecting hole that links to each other with ring flange, and the both ends of the surface up and down of installing hole are respectively equipped with first, second insulation cushion on the described cantilever; Be provided with the insulation disc between shaft coupling and the ring flange, be provided with insulating sleeve in the connecting hole on the shaft coupling.
Can know by technique scheme; The utility model is provided with insulating part at above-mentioned position; Induced emf that produces in the time of can guaranteeing electronic big bus owing to the electric machine controller drive motors and the insulation between the car body prevent that induced electromotive force from conducting on the car body, guarantees the security and stability of electronic big bus.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Like Fig. 1, a kind of electronic big bus shown in Figure 2 insulation system with drive motors; Motor 1 shell is provided with cantilever 2, and cantilever 2 is provided with installing hole, and cantilever 2 directly is welded on motor 1 shell; The installing hole on the cantilever 2 and the chassis of electronic big bus fix; The output shaft 3 of motor 1 links to each other with shaft coupling 4, and shaft coupling 4 is provided with the connecting hole that links to each other with ring flange 5, as the preferred version of the utility model; The upper/lower terminal face of installing hole is respectively equipped with first, second insulation cushion 6,7 on cantilever, can prevent that like this housing of motor 1 and the car body of electronic big bus from keeping insulation; Be provided with insulation disc 8 between shaft coupling 4 and the ring flange 5, be provided with insulating sleeve 9 in the connecting hole on the shaft coupling 4, can guarantee the insulation between motor shaft coupling and the ring flange like this.Through above-mentioned seal is set; Can guarantee fully on the electronic big bus because induced electromotive force that produces during the electric machine controller drive motors and the insulation between the car body prevent that induced electromotive force from conducting on the car body, influences the fail safe of electronic big bus; This is simple in structure simultaneously; Low cost of manufacture, easy maintenance and installation, the electric automobile stability and the fail safe of drive motors in motion is protected.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection range of the utility model claims.
