Description

Full-automatic cone slipper screw driving wheel type motor vehicle slipping equipment

The present invention relates to the automatic control of drive unit, be used for realizing rotating synchronously or sliding between semiaxis and the wheel hub.

Motor vehicle based on automobile are most widely used in the traffic in modern times, power consumption at most, pollute also the most very, therefore the energy-conservation problem that has just become people to pay close attention to the minimizing pollution, save the energy, reduce that to pollute be the good method that addresses this problem with being located at glider between semiaxis and the wheel hub, thereby the research glider is a lot of, but pay very few that Chu implements, though its reason is complicated, technical defective yes one of reason.The previously disclosed a kind of newer convenient to load and transport cone slipper convex-concave of the inventor drives wheeled motor-vehicle skid, though use reliable, but still have deficiency, belonging to rigid with regard to ratchet in its lockable mechanism and ratchet contacts, unablely bear its impact load and damage, influence using effect, handling ratchet separates with ratchet and the mechanism that combines, because of limit by its relative movement,, very easily rise and handle error so component are more, also influence using effect, convex-concave driving wheel precision prescribed height is made difficulty, is difficult to form produce in batches.

The objective of the invention is to disclose a kind of cone slipper screw driving wheel type motor vehicle glider of automatically exempting to handle.

Its scheme is: a kind ofly automatically exempt to handle the cone slipper screw driving wheel type glider, be located between semiaxis and the drive hub, constitute by free wheel device and automatic locking locking apparatus, it is characterized in that deducting complicated locking control mechanism, make its locking automation, it is lighter and handier that complete machine becomes, change the convex-concave driving wheel into screw driving wheel and make that operation is flexible freely, its free wheel device is mainly by cone slipper, screw driving wheel, torsion spring advances, inner conical surface shell and pressure bearing, conical bearing constitutes, the inner conical surface shell of glider is connected with bolt with wheel hub, screw driving wheel and semiaxis keyed jointing, the automatic locking locking apparatus is by being enclosed within the torsion spring of moveing backward on the male cone (strobilus masculinus) shoe surface, one end of reversing torsion spring is a fixed end, and the other end is a control end, and control end is subjected to cased eccentric little axle, tooth bar, gear, tapered cup nut is controlled automatically.

Compare with correlation technique, owing to be contained in semiaxis outer end, the wheel hub outside, the bearing load not so whole glider only bears driving torque, corresponding do small but excellent of component, removed loaded down with trivial details control mechanism again from addition, change the convex-concave driving wheel into screw driving wheel, not only cost is low, and more convenient easy row is installed.

The present invention will be further described below in conjunction with accompanying drawing and embodiment.

Fig. 1 is a structure installation diagram of the present invention;

Fig. 2 controls schematic representation automatically among the embodiment;

Fig. 3 is that torsion spring is subjected to eccentric shaft to be controlled in lock position and sliding position schematic representation among the embodiment.

Embodiment is a glider that is made of free wheel device and automatic locking locking apparatus, clutch is made up of three primary components, the inner face of seeing screw driving wheel 14 among Fig. 1 is a cylindrical shape, being enclosed within semiaxis 1 upper spline connects, centre circle also is a cylindrical shape, its surface and 15 sliding joining of slide block, its right-hand member helical tooth is meshed with slide block left end helical tooth, the outer surface of slide block is the cylndrical surface, be with two torsion springs 25 that rotation direction is opposite in the cylndrical surface, 26,25 are reversing or locking torsion spring, 26 are the torsion spring that advances, and the slide block right side is the truncated cone, so claim cone slipper, the interior left side of shell 18 is a barrel surface, the right side is an inner conical surface, thus name inner conical surface shell, for connection and concerted action also are provided with some attached components, as pressure bearing conical bearing 19, stage clip 20, heading 21, pressure ring 22, snap ring 23,24,27,28,29,30, bolt and taper washer are that glider is fixed in the wheel hub outside.

The cone slipper 5 that the automatic locking locking apparatus is screwed by set screw nut 4 that has outer spiral shell mosquito and outside thread, little torsion spring 8 and torsion spring driving casing 9 are housed in the right inner cylindrical surface of slide block 5, torsion spring set the other end on the outer surface of driving casing 9 is stuck in the groove of slide block 5, the internal surface of its torsion spring set 9 is carved with spline and semiaxis keyed jointing, the little axle of tooth bar 10 is meshed with sprocket wheel 7, the gearwheel 2 of sprocket wheel is meshed with the small gear of eccentric wheel left end band free wheel device, as 12 among Fig. 2.

When using present embodiment to start vehicle, semiaxis 1 is being with screw driving wheel 14 to rotate together, the cone slipper 15 that is enclosed within on the drive wheel outer surface certainly will rotate synchronously, for stopping to rotate synchronously male cone (strobilus masculinus) can not be moved and situation appearance like the inner conical surface association class outward, on male cone (strobilus masculinus), be with the torsion spring 26 that advances, one end of spring is fixed on the shell as 26 indications, like this under the restriction of unidirectional torsion spring, the torsion of the helical tooth on the driving wheel force the male cone (strobilus masculinus) slide block axially outer move with inner conical surface in conjunction with and drive wheel hub and rotate, to reach the purpose of automobile running, Panasonic's throttle when garage sails to certain speed, the semiaxis rotating speed descends suddenly, cone slipper is owing to lost the moment of torsion that semiaxis transmits, speed difference in causing between male cone (strobilus masculinus) and separating, the male cone (strobilus masculinus) slide block separates with inner conical surface under the promotion that adds the pressure spring on the male cone (strobilus masculinus) right side under the inner conical surface promotion at a high speed, realized the purpose of free sliding, the torsion spring that advances of this moment trackslips on shoe surface with the direction of loosening, thoroughly free the above various resistances of semiaxis, reached the purpose of free sliding.When automobile need be moveed backward, the semiaxis backward rotation, the torsion spring set 8 of keyed jointing rotates together with it, one end of the torsion spring on the torsion spring set 8 is fixed on the cone slipper 5, also just drive it with changeing, because of the internal thread of slide block is meshed with set screw nut 4, add that set screw nut 4 is static, because relative rotary motion is outwards moved at the promotion lower shaft of screw thread power, force tooth bar 6 axial outer moving, change together with the small gear 7 coaxial drive gearwheels of tooth bar engagement, pinion on gearwheel and the eccentric wheel drives free wheel device and does rotation motion, stir the control end of the reversing torsion spring 25 of male cone (strobilus masculinus) shoe surface, make itself and male cone (strobilus masculinus) form intermittence and contact, and lose its torque force, the restriction when not slided by it, semiaxis continues backward rotation and eccentric shaft is gone to the control position when reversing or locking, makes the reversing torsion spring state that affranchises produce moment of torsion and play latch functions.These actions come work done by automobile itself fully, thereby this glider becomes genuine Glider automatic.
