Moveable reverse gear shaft 18 is inserted in the hole of casing, reverse gear shaft is installed with reverse speed fork 19, and the jaw of shift fork is inserted in the annular groove that reverse gear shaft puts.
The shifter of reverse gear shaft is installed on casing top.It is a reverse lever 16 removed the rotating reverse lever axle 15 of hand-guided by reverse gear in operator cabin and be connected with reverse lever axle with spline, and the head of reverse lever is inserted in the oblong aperture that reverse gear shaft is outputed.
Casing is provided with the locking device of reverse gear shaft.What locking device adopted is spring 10 steel ball 11 formula structure, and reverse gear shaft has two grooves, steel ball is stuck in one of them groove.
The casing of reverse gear shaft rear end is provided with Reverse lamp switch 20.
At rear output shaft rear portion, speed measuring apparatus is installed.Odometer actuation gear 27 in this device is fixedly connected with rear output shaft rear portion with spline.Gear on gear shaft 29 is meshed with odometer actuation gear.The two ends of gear shaft are connected with casing with Spielpassung, and the spindle nose of upper end is connected with odometer line end.
Working principle of the present invention: after engine start, vehicle is in idle running, and due to car body deadweight, output shaft has load, and the planet carrier be connected with output shaft does not rotate.The power of input shaft passes to passive magnet rotor through gear ring, planet wheel, sun gear, gear bush, and passive magnet rotor is rotated backward.These gears are all fixed shaft gear trains, surely than transmission.When opening the throttle gradually, the rotating speed of these gears improves gradually, and the reverse speed of passive magnet rotor is also improving constantly.Now vehicle is still motionless, and active and passive magnet rotor is in separated state.Want to make vehicle start and acceleration, only have and rotate speed governing axle, make the speed governing shift fork on speed governing axle stir active magnetic rotor, make it shift to passive magnet rotor.Due to the magnetic field mutual induction of active and passive magnet rotor, when active magnetic rotor turns, passive magnet rotor produces the magnetic induction moment of a forward.Shift in the process of passive magnet rotor at active magnetic rotor, this moment continues to increase, and the reverse speed of passive magnet rotor is constantly reduced, and after zero-speed, forward rotational speed constantly increases.The reverse speed of sun gear also constantly reduces, and after zero-speed, forward rotational speed constantly increases.Now the rotation rotating speed of planet wheel starts to reduce gradually, and the revolution rotating speed of forward increases gradually by zero-speed, drive output shaft to rotate forward, and rotating speed increases gradually by planet carrier.When active magnetic rotor is near passive magnet rotor, the speed discrepancy of active and passive magnet rotor reduces gradually.When active and passive magnet rotor laminating, the rotating speed of two magnet rotors is identical, and namely input shaft and output shaft synchronous rotate, and enter direct high.
Rotate backward speed governing axle, make active magnetic rotor leave passive magnet rotor gradually, the rotating speed of output shaft reduces gradually, with most zero-speed, so just achieves stepless change.
The power of input shaft is divided into two-way transmission: a road through gear ring, planet wheel, pass to planet carrier.Another road passes to planet carrier through active magnetic rotor, passive magnet rotor, gear bush, sun gear, planet wheel.The power of two-way is combined into a road on planet carrier, is exported by output shaft, and the transmission achieved with speed change in Gear Planet Transmission is inputted by sun gear, is inputted by gear ring with the transmission determining ratio, and two kinds of transmissions are combined, and are exported by planet carrier with the transmission of speed change.
During reversing, first move reverse gear spanner to reverse gear by former shelves, reverse gear axle sleeve exits front output shaft spindle nose by the spindle nose being sleeved on front and back two output shaft, all enters rear output shaft, has departed from front output shaft.The external splines of reverse gear axle sleeve enters in the internal spline of bevel gear III.Rotate speed governing knob subsequently to acceleration direction, active and passive magnet rotor is drawn close gradually by being separated.The power of front output shaft oppositely passes to rear output shaft through bevel gear I, bevel gear II, bevel gear III, and these gears are all the transmissions of to, just change direction, and the rotating speed of output shaft is controlled by speed governing knob.Move backward complete, reverse gear spanner is moved back to former shelves, reverse gear axle sleeve leaves bevel gear III, and be socketed in the spindle nose of front and back two output shaft, speed governing knob goes back to original position, and active and passive magnet rotor is separated.
Range of infinitely variable speeds: output shaft rotating speed consecutive variations between zero-speed and maximum (top) speed.When input shaft invariablenes turning speed, output shaft rotating speed can be increased to maximum (top) speed by zero-speed, can reduce to zero-speed again by maximum (top) speed, can fix arbitrarily a certain rotating speed between zero-speed and maximum (top) speed.When input shaft rotation speed change, output shaft also can be made to be fixed on a certain rotating speed.No matter much input shaft rotating speed is, and output shaft rotating speed all can be zero-speed.These are all that other speed changer is unrivaled.
The invention belongs to gear transmission, stable drive, accurately, reliable, be therefore widely used in all mechanical speed changes such as automobile, train, aircraft, steamer, Aero-Space, instrument and apparatus, feeler mechanism, machining, weight industry.It can replace any one speed changer, is current optimal speed change gear.The present invention is due to simple to operate in the application such as automobile, tractor, motorcycle, and speed governing is convenient, and everybody can drive, and not easily causes trouble.Because speed change is fast especially, be applicable to car, racing car, bullet train etc.Because having a power failure, just can shut down, also be applicable to the machinery of often shutting down.Increase load when starting electrical machinery gradually by dallying, can not because of startup motor damage.In sum, the present invention is in the Economy of fuel oil, the discharge amount of waste gas, the cost manufactured, powerful power character, good startability, the advantage of the aspect such as the travelling comfort of the stationarity of acceleration, transmission smoothly, the flexibility of manipulation, driving, efficient, energy-conservation, safety, environmental protection is that market similar technique product is impayable.Technology leading in the world, high value-added product, the wide market demand, Social and economic benef@is remarkable.
