Abstract
The utility model discloses a hub motor having a shock absorption function. The hub motor comprises a rotor, a stator and a motor shaft, and is characterized in that a loop of shock absorption rubber cushion is disposed on an outer circle of the housing of the rotor, and at the same time, the rotor housing is provided with a flange plate extending outward on the one side where the shock absorption rubber cushion is located; a screw hole is disposed on the flange plate; a wheel disc of the hub is sleeved on an outer circumference of the shock absorption rubber cushion, and is fixedly connected with the flange plate through a fastening screw. The hub motor having the shock absorption function alleviates shocks that the motor suffers during a driving process, guarantees normal operation of the motor, prevents the motor from getting damaged due to long-time shocks, and prolongs service life of the motor.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of wheel hub motor with shock-absorbing function.
Background technology
At present, the permanent magnet DC motor that uses in the electric motor car adopts the hub-type design more, and namely stator is positioned at internal rotor, and the rotor case of motor is directly fixedlyed connected with wheel hub.Because motor is arranged on the wheel, produce vibrations in the process of moving unavoidably, tire can play certain cushioning effect, but still has major part to be passed to the motor place, and motor is caused damage, influences its working life.
The utility model content
For overcoming above-mentioned technical problem, the utility model provides a kind of cushioning effect that carries, and can alleviate the wheel hub motor of the suffered vibrations of motor in the driving process.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of wheel hub motor with shock-absorbing function comprises rotor, stator and motor shaft; Stator is positioned at rotor, and fixedlys connected with motor shaft; Connect wheel hub on the rotor case; It is characterized in that: the housing cylindrical of rotor is provided with a circle damping rubber cushion, and rotor case is provided with outward extending ring flange in damping rubber cushion one side simultaneously, and ring flange is provided with screw; The wheel disc of wheel hub is nested with on damping rubber cushion cylindrical, and fixedlys connected with ring flange by holding screw; Described damping rubber cushion available buffer wheel disc and rotor active force diametrically.
The utlity model has following beneficial effect: owing to be provided with the damping rubber cushion between wheel hub and the motor, can slow down the vibrations that motor is subjected in the driving process, avoid long-time vibrations and motor is caused damage, guarantee its operate as normal, prolong its working life.
