Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The wheel of the built-in power set that the present invention provides, illustrates in conjunction with the scalable axis angle device provided, including
Module 1 and module 2 two parts.Scalable axis angle device is as shown in module 1 in Fig. 1, in built-in power set such as Fig. 1
Module 2.
Scalable axis angle device includes outside input connection member 1, universal ball joint 2 and universal output block 3.Outside
Input connection member 1 is connected interface for offer with external component, is connected with external power source, in order to the rotation for wheel provides energy
Source.Outside is inputted connection member 1 by universal ball joint 2 and universal output block 3 connects.
Universal ball joint 2 mainly includes Internal Spherical Surface and the spherical sleeve being connected, and major function is to provide different angles, and leads to
Cross the fastening between universal output block 3 and spherical sleeve and fix the angle of regulation, it is achieved the normal operation of wheel.Outside defeated
Enter connection member 1 one aspect to be connected with the Internal Spherical Surface of universal ball joint 2, change angle, the opposing party with the rotation of Internal Spherical Surface
Face forms a unified interface, is connected with other modules beyond wheel, such as, is connected as the rotation of wheel with power module
The energy is provided.Universal output block 3 one end connects spherical sleeve, and the other end fixes connecting power device fixed mount 4.Universal defeated
Go out together with parts 3 and power set fixed mount 4 be fastenedly connected by screw etc., be used for connecting installation power set.
When need not axis angle can timing, the module 1 in Fig. 1 can simplify and is an externally input connection member 1, and outside input is even
Relay part 1 is directly connected to power set fixed mount 4.
Built-in power set include power set fixed mount 4, secondary bearing bearing 5, tire outer ring 6 and outer wheel hub 7.Dynamic
Power apparatus fixed mount 4 is for carrying and the fixing power set being built in wheel.
In the embodiment of the present invention, power set fixed mount 4 is designed as the fixing one being connected with universal output block 3, for solid
Determined power device.By secondary bearing bearing, power set are coordinated with tire outer ring 6 by bevel gear 8, and form phase
To rotation.Built-in power set refer to the device of motor etc, and motor is placed in power set fixed mount 4, is turned by electric energy
Turning to mechanical energy, the rotation for wheel provides power.By built-in power set, wheel need not will rotation by external motor
Rotatory force is entered by power transmission shaft transmission.
The present invention use a kind of secondary bearing bearing 5 support tire outer ring 6.Secondary bearing bearing 5 includes K
Individual little bearing, in present example, K is equal to 4.As it is shown on figure 3, the outer ring of secondary bearing bearing 5 is tire outer ring 6,
Inner ring is power set fixed mount 4, four common little bearing annular spread equably in the inner side of tire outer ring 6, four bearings
Inner ring fixed by the inner ring (i.e. power set fixed mount 4) of stud and secondary bearing bearing 5 and be connected, four bearings
Outer ring contact with the inner slide inside tire outer ring 6.Secondary bearing bearing 5 passes through outer ring and the wheel of four little bearings
Tire outer ring 6 Structure deformation.Utilize secondary bearing bearing to solve the problem of bearing size and weight, save tire further
Inner space, optimizes load-carrying construction.
Tire outer ring 6 is designed with bevel gear, matches with the bevel gear of power set, and relative interior rotates, simultaneously tire
Outer ring 6 has the width inner slide equal to the thickness of the little bearing in secondary bearing bearing 5, at secondary bearing bearing
Under the support of 5, uniform stressed, smooth rotation.
Together with outer wheel hub 7 shown in Fig. 1 is fastenedly connected with power set fixed mount 4.Then outer wheel hub 7 also holds with secondary bearing
Power apparatus 5 is fixing to be connected.Universal output block 3, power set fixed mount 4 are integrated with outer wheel hub 7 three's integrated connection,
Manually rotating outer wheel hub 7, can drive universal output block 3 to rotate, it is achieved wheel axis angular adjustment, by universal defeated
The spherical sleeve fastening going out parts 3 and universal ball joint 2 fixes the angle of regulation, thus can reach regulation fixing vehicle wheel axle
The purpose of line angle degree.
Outer wheel hub profile that the outer wheel hub 7 of the present invention is different Yu traditional and structure, the outer wheel hub 7 of the present invention is not used to support wheel
Tire outer ring 6, its effect is so that tire appearance is attractive in appearance, and when needs adjustment axis angle, it is provided that one is prone to manual operations
Rotary part 8.As shown in (a) and (b) of Fig. 4, the outer wheel hub 7 of the embodiment of the present invention includes a circular curved surface list
Sheet, is provided with a rotary part 8 being prone to handmade rotary, and rotary part 8 is fixedly connected on power set fixed mount 4
On.By operation rotary part 8, the universal output block 3 that be connected fixing with power set fixed mount 4 can be driven to forward to.
In conventional wheel, by external motive device drive shaft, and then driving vehicle wheel rotation, external motive device passes through reduction box,
Clutch even flowing, has certain mechanical loss.The wheel of the present invention passes through built-in power set, by being arranged on power dress
Putting fixed mount and eliminate the transmission demand of itself from outside tires to wheel, whole transmission all realizes in inside tires, external connection
Axle only serve load effect, so, whether horizontal direction or vertical, all can arbitrarily regulate wheel face and axle
The angle of line, controller part, also in wheel, provides the energy as long as outside, just can drive built-in power set, will
Electric energy is converted into mechanical energy, drives wheel turns, and the design of this Highgrade integration makes it have the higher suitability.
