Abstract
The present invention relates to a kind of wheel driver, with torque motor, wheel center position is installed on, the rotor periphery installing wheel of torque motor, torque motor stator and car body are affixed；The torque motor includes rotor, stator and bearing, and wherein rotor is installed on outside stator by bearing, and permanent magnet is installed on rotor core, armature winding is installed on stator core, also there is axle, it is fixedly and coaxially connected with stator and is integrated, and stator is connected by axle with car body.By the present invention in that the torque motor rotated with a kind of outer ring, reduces the axial length first mate of drive component, solve the problem of wheel driving assembly axial length is excessive, and this type of drive can expand the use scope of omnidirectional's car.
Description
Technical field
The present invention relates to a kind of wheel actuation techniques, specifically a kind of wheel driver.
Background technology
Existing omnidirectional's car, it is general to use motor acceleration and deceleration machine, it is connected by wheel shaft with wheel, it is whole dynamic
Power length component depends on the length of motor, reductor, wheel shaft etc., causes whole Power Component length
It is longer, but client is frequently necessary to the narrow vehicle of car body, it is desirable to and axial distance will during design motivation system
As far as possible short, to meet the demand of different clients.
Simultaneously as using upper limitation, omnidirectional's car frequently encounters drive component in design and installs empty
Between it is not enough the problem of, the application of omnidirectional's car is diminished.
And it is current, meeting the wheel driver of the demand, there is not been reported.
The content of the invention
Whole Power Component length for the wheel of omnidirectional's car in the prior art is longer, it is impossible to meet visitor
Family is frequently necessary to the narrow vehicle of car body, and this is not enough, and the technical problem to be solved in the present invention is to provide one kind
The short wheel driver of axial distance.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of wheel driver of the present invention, with torque motor, is installed on wheel center position, power
The rotor periphery installing wheel of torque motor, torque motor stator and car body are affixed.
The torque motor includes rotor, stator and bearing, and wherein rotor is installed on fixed by bearing
It is sub outer, installed on rotor core and armature winding is installed on permanent magnet, stator core, also with axle, its
It is fixedly and coaxially connected and is integrated with stator, stator is connected by axle with car body.
The torque motor is direct current generator.
The bearing is nonlubricated bearing.
Wheel is Mecanum wheel.
The invention has the advantages that and advantage：
1. by the present invention in that the torque motor rotated with a kind of outer ring, makes the axial length of drive component
First mate reduces, and solves the problem of wheel driving assembly axial length is excessive, and this type of drive
The use scope of omnidirectional's car can be expanded.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the torque motor structure side view in the present invention；
Fig. 3 is torque motor structure front view.
Wherein, 1 is rotor core, and 2 be permanent magnet, and 3 be bearing, and 4 be stator core, and 5 be armature
Winding, 6 be axle, and 7 be wheel, and 8 be rotor, and 9 be stator, and 10 be car body.
Embodiment
With reference to Figure of description, the present invention is further elaborated.
As Figure 1-3, a kind of wheel driver of the invention, with torque motor, is installed on wheel
Center, the outer rim installing wheel 7 of rotor 8 of torque motor, torque motor stator 9 and car body 10
It is affixed.The torque motor includes rotor 8, stator 9 and bearing 3, and wherein rotor 8 passes through bearing
3 are installed on outside stator 9, and permanent magnet 2 is installed on rotor core 1, install on stator core 4 armature around
Group 5, also with axle 6, it is fixedly and coaxially connected with stator 9 and is integrated, and stator 9 passes through axle 6 and car
Body 10 is connected.
In the present embodiment, wheel uses Mecanum wheel, and torque motor uses rimless DC brushless motor,
It is structurally characterized in that rotor 8 in outer ring, and stator 9 is in inner lane, by electrical control gear with servo control
The direct low-speed big driving Mecanum wheel of mode of system, subtracts the axial length first mate of drive component
It is small, solve the problem of Mecanum wheel drive component axial length is excessive, and this type of drive
The use scope of Mecanum wheel can be expanded.
The bearing in the present invention is nonlubricated bearing simultaneously, eliminates the workload that bearing maintenance is brought.
