Description
Technical field
the utility model relates to industry and technical field of vehicle, particularly relates to motor mechanism.
Background technology
At present, in vehicle and industrial technical field, the form of motor mechanism is varied, and along with oversize vehicle and power-actuated needs, often need to adopt the larger motor of power or generator, especially in hybrid vehicle, this application is extensive especially.But these powerful motors or generator ubiquity volume are comparatively large, heavier-weight, the shortcoming that price is also quite expensive, and in use once break down, just can not meet normal need of work, and it is very inconvenient to use.
Utility model content
The purpose of this utility model is to provide a kind of planetary mechanism that adopts that multiple motor is carried out the motor mechanism of power coupling, adopts the awkward problem of single heavy-duty motor in order to solve.
A kind of motor mechanism of the present utility model adopts following technical scheme: motor mechanism, comprise planetary gear mechanism, described planetary gear mechanism comprises sun gear, ring gear, planetary gear and planet carrier, described motor mechanism also comprises motor, the rotor of motor is with one of them in stator for being fixedly connected with planet carrier, and another is for being connected with planet gear transmission and driving planetary gear to rotate around its axis.
Described sun gear is concentric and arrange at fore-and-aft direction relative spacing with planet carrier, and described motor has two or more and circumference to be distributed on planet carrier and corresponding with the annular section between sun gear and ring gear in the longitudinal direction centered by the center of circle of sun gear.
Described sun gear, ring gear and planet carrier wherein at least one is provided with central shaft, this central shaft is power output shaft for transmission of power or power input shaft.
Motor mechanism of the present utility model comprises planetary gear mechanism, described planetary gear mechanism comprises sun gear, ring gear, planetary gear and planet carrier, described motor mechanism also comprises motor, the rotor of motor is with one of them in stator for being fixedly connected with planet carrier, and another is for being connected with planet gear transmission and driving planetary gear to rotate around its axis.The power of multiple motor is coupled by being connected with planetary gear direct-drive by motor by this motor mechanism, the power output provided is larger, and the cost that a heavy-duty motor also reduces whole mechanism replaced by multiple low-power machine, simultaneously, a motor break down and cisco unity malfunction time, whole mechanism also has other motor rotations and whole mechanism can not be caused can not to carry out Power output or input, repairs or replaces separately when keeping in repair or change to the motor broken down.

Embodiment
The embodiment of a kind of motor mechanism of the present utility model: as Figure 1-3, comprise ring gear 2 and the sun gear 1 that arrange concentric on ring gear 2, the diameter of sun gear 1 is less than the diameter of ring gear 2, between the periphery of sun gear and the inner ring of ring gear, there is annular space, this annular space internal messing is equipped with planetary gear, multiple motor 3 is evenly equipped with in the position circumference centered by the center of circle of sun gear corresponding to this annular space, the rotor 4 of motor is connected with the planet gear transmission being positioned at annular space, motor mechanism in the present embodiment is used as Power output, motor is drive motors, planet carrier is relatively fixing, motor stator is fixed on planet carrier 6, planet carrier 6 is circumferentially with multiple fixed installation hole 40 coordinated with the rotor turns of drive motors, the axis of planet carrier 6 all overlaps with the axis of sun gear and ring gear, rotor is through fixedly mounting hole and being deep in the annular space sun gear and ring gear, rotor shaft is fixedly connected with planetary gear, sun gear and ring gear can be driven to sun gear and ring gear to rotate by planetary gear transferring power during the rotor turns of drive motors, the sun gear central shaft 5 that sun gear 1 and ring gear 2 are arranged respectively by its center and ring gear central shaft 20 outputting power.The power of motor is directly passed to planetary gear by this motor mechanism, and be coupled by the power of planetary mechanism by multiple motor, improve bearing capacity and the power of whole motor mechanism, the cost that the independent heavy-duty motor of employing one saves whole mechanism is compared in multiple motor power coupling, simultaneously when a motor of whole mechanism breaks down or damages, directly maintenance taken off to this motor or change, easy to maintenance, do not affect the running of whole mechanism yet.
In the present embodiment, motor stator is fixed on planet carrier, and rotor is connected with planet gear transmission, and in other embodiments, motor can adopt wheel hub motor, and now, motor stator is connected with planet gear transmission, and rotor is directly fixed on planet carrier.
In the present embodiment, sun gear and ring gear have central shaft, motor is drive motors, drive motors outputs power and passes to sun gear central shaft and ring gear central shaft, in other embodiments, ring gear can be fixed, sun gear and planet carrier can be provided with central shaft, power can be passed to sun gear and planet carrier by drive motors respectively, certainly, motor also can be generator, ring gear is fixed, the central shaft of sun gear is as power input shaft, sun gear rotates and power is passed to generator by planetary gear, thus be electric energy by power conversion, the input and output form of planetary transmission system is more, repeat no longer one by one herein.
In the present embodiment, the rotor of drive motors to be directly deep in annular space and to be fixedly connected with planetary gear, in other embodiments, rotor can not go deep into annular space or not corresponding with annular space in the longitudinal direction, and be connected with planet gear transmission by other drive mechanisms such as gear and sprocket wheels, the present embodiment is only to provide the comparatively simple structure of a kind of structure.
In use, sun gear central shaft, planet carrier central shaft and ring gear central shaft all can input or output end as transmission of power to motor mechanism of the present utility model, this motor mechanism be used as power input time, can be electric energy by power-conversion; When this motor mechanism is used as Power output, can be power by electric energy conversion; When as power coupling parts, both can as power input mechanism, also can as power take-off mechanism, be coupled by the power of planetary mechanism by multiple motor, improve bearing capacity and the power of whole mechanism, reduce the volume of whole mechanism, reduce use cost, use, keep in repair also more for convenience.
