Abstract
The utility model relates to an encoder and brake all-in-one structure used for an electric vehicle, which is applied on a rear end cover of a motor. The structure organically combines a brake with the rear end cover of the motor, and the design of a fan on a brake rotor can provide the radiating function, thus leading the radiating structure of the motor to be more reasonable. The rear end cover of the motor is directly used as a brake friction disc, thus forming an all-in-one structure of the brake and motor. Therefore, the verticality of a friction plane and a motor shaft is ensured, and the stability of the braking performance is also ensured. Simultaneously, the friction discs at two sides generate the effect of 'double braking discs', and the effect is two times that of a single braking disc, thus solving the problems that the diameter of the brake is overlarge in large-power occasion, and is inconsistent with the external appearance size of the motor. In addition, as the rear end cover of the motor is also a part of the brake, good condition is created for the sealing of the brake, the cleaning and drying of the friction disc of the brake are more favorably ensured, and the fault possibility of the brake is greatly reduced.
Description
Technical field
The utility model relates to the electric motor structure in a kind of electric motor car, a kind of specifically structure that the motor of brake and electric motor car is integrated.
Background technology
Traditional motor and brake are separate parts, and brake and motor are assembled together.The problem that such structure is brought comprises: the axial dimension of motor is long, and waste of material is serious; Outward appearance is inharmonious, and is particularly more obvious in powerful occasion; Compatible problem appears in two discrete parts easily, so fault is more.
And for the electric machine of electric motor car now commonly used, owing to require its simple in structure, lightweight characteristics, the volume that general motor and brake together can aggrandizement apparatus can not satisfy the motor requirement of electric automobiles.
The utility model content
The purpose of this utility model provides a kind of integrally-built motor and brake design, and solve the motor of conventional electric motor car and the structure of brake separate type: the axial dimension of motor is long, and waste of material is serious; Outward appearance is inharmonious, and is particularly more obvious in powerful occasion; Compatible problem appears in two discrete parts easily, so the more problem of fault.
The purpose of this utility model is to be achieved through the following technical solutions:
Electric vehicle encoder and brake integrated structure, be applied on the rear end cap of motor, exterior lateral sides at rear end cap is installed frictional disk, the inner encoder stator of installing of rear end cap, corresponding encoder stator is installed the encoder rotor on motor shaft, and by the encoder fastening bolt encoder rotor is fixed, described encoder stator, encoder rotor are positioned at the outside concave interior of rear end cap; Another frictional disk is installed on the electromagnetic brake seat, the brake axle sleeve is installed on the motor shaft, brake shaft puts the installation brake rotor, the card of described brake rotor is between two frictional disks, brake rotor is provided with fan structure, and friction plate is installed in the both sides at brake rotor, and the outer surface of friction plate contacts/separates with two frictional disks respectively.
The technical scheme that the utility model provides has realized the perfect adaptation with brake and motor, the rear end cap of brake and motor is combined, and the design of the fan on the brake rotor can provide the function of heat radiation, can make the radiator structure of motor more reasonable.The technical program utilizes back end cover for motor directly to serve as brake disc, forms brake and motor integration structure.When so just having abolished original independent frictional disk structure, make the perpendicularity of frictional plane and motor shaft that assurance arranged, also just guaranteed the stable of braking ability.Simultaneously, the bilateral frictional disk produces the effect of " two brake disc ", and its effect is but 2 times of brake disc that it is too big to have solved large-power occasions brake diameter, with the inharmonic problem of the apparent size of motor.In addition,, thereby created good condition, more helped guaranteeing cleaning, the drying of brake friction dish, the possibility of brake troubles is greatly reduced for the sealing of brake because back end cover for motor also is parts of brake.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
