The first order worm screw fixed form of the second level worm screw linkage second level driving cog of wheel, the driving motor and one-stage gear is riveting
Connect fixation.
Further, one end of first order wrom tooth connects rolling bearing；First order wrom tooth and second level worm screw are coaxial, and second
One end of grade worm screw connects deep groove ball bearing.
Further, angular transducer is mounted on sensor installation seat, and second level driving cog is output gear, the output
The end of gear is fixedly connected with angular transducer.
Further, after motor power of the present invention is converted by transmission mechanism, the rotary motion for output shaft of shifting gears and automobile
Gear shift transmission driving lever input shaft axis of movement is consistent, is directly connected to that power can be passed to shifting vehicle gearbox shift lever axis
On, it does not need connecting rod etc. and moves conversion again.
Further, the power of actuator is directly passed to gear shift transmission, transmission essence by gear drive by the present invention
Degree is high.
Further, second axis spring bearing one end of the invention uses rolling bearing, and one end uses sliding bearing, is conducive to
The adjustment of axial gap when axis thermally expands.(rolling bearing that former one end is substituted in sliding bearing), and on the same axis using a left side
It revolves with the design method of right-hand teeth and reduces axial force.
Gear shifting operator of the present invention is for structural point, possessed beneficial effect and feature:
1, in use, angle (shift) sensor is installed to actuator enclosure interior of the invention, second driving shaft is utilized
End space is fixed.It does not need individually to seal, and existing angular transducer needs housing close outside actuator shell at present
Envelope.
2, the motor power input terminal that the present invention uses is using push-in connection, and assembly is simply, conveniently.
3, motor shaft of the present invention and worm screw axis connection are connected directly by interference fit, without passing through shaft coupling, in this way
So that space substantially reduces.
4, the worm gear on the second axis of the invention uses helical teeth, axial force suffered by the axial force and gear on worm of the course of work
On the contrary, the axial force being transmitted on spring bearing can be greatly reduced, bearing service life is improved.
5, the fixed structures such as motor and worm shaft of the present invention, using spring extrusion type fixed form, structure is simple, assembly side
Just.
Gear shifting operator of the present invention is for manufacturing process angle, possessed beneficial effect and feature:
1, output shaft and sector gear of the present invention use monoblock type manufacture, can be manufactured using metallurgical powder monoblock type
Mode manufactures, good manufacturability.
2, motor of the present invention, bearing etc. are fixed in actuator shell is squeezed using spring, and riveting is fixed, assembly technology letter
It is single, reliable.
3, the fixation of control circuit board of the invention in controller housing uses snap, and assembly technology is simple.
To sum up, automobile gear shift actuator wide application of the invention occupies little space since overall volume is relatively small.
Both it can be used in new-energy automobile, autonomous driving vehicle shift, conventional fuel oil automobile handle mode can also be replaced and shifted gears.And
Shift actuator is connect with automobile shifting transmission, and transition bracket is needed to connect, and transition bracket shape also expands with respect to flexible design
Big shift actuator application range.
