In this first speed regulator 21, the tooth cover continuous undulating teeth groove of 215 and the production method of the continuous undulating double wedge of output member 212 are: draw the ring-like wave-like line that all crests and trough are same radius; After the equidistant translation in both sides, two ring-like wave-like lines are drawn centered by this ring-like wave-like line; With this two ring-like wave-like line newly painted for benchmark makes this ring-like continuous undulating teeth groove and double wedge; This ring-like continuous undulating teeth groove 2151 all does fillet process with identical radius with the intersection of all planes of double wedge 2121.

In this first speed regulator 21, the assembling mode of roller group 214 is: be inserted in this spring 2143 outside the hollow circuit cylinder of this second disk body 2142;

The hollow circuit cylinder of this second disk body 2142 to be inserted in the bearing 2131 in this support 213 through hole near the side of Power output by this support 213, it is axial movable that this bearing 2131 need make the hollow circuit cylinder of this second disk body 2142 can do in this bearing 2131; The cylinder of the first disk body 2141 is inserted in the hollow circuit cylinder of this second disk body 2142 by the another side of this support 213; The cylinder of this first disk body 2141 protrudes from this second disk body 2142 another side place button and establishes a clasp.

In the present invention, by the first live axle 310, second live axle 320 and the 3rd live axle 330 are formed the arranged in parallel of the wheelbase such as not around this output shaft 340 centered by this output shaft 340, and each shifting gear and synchronizer are set on each live axle, thus be achieved in the effect increasing transmission of power gear number in the confined space, in Fig. 5 to Fig. 7, size due to this roller group 214 traction drive power is directly proportional to the pressure size of pressing point between this input component 211 and this output member 212 to this roller group 214, therefore the shift fork F by controlling to control by power mechanism puts on the pressure size of the output member 212 of this first speed regulator 21, make the crawling function that gearbox of the present invention can provide vehicle smooth-going when low speed starting or upward slope state, and each speed regulator component excessive wear in this speed regulator room 20 can not be caused, thus to avoid in prior art clutch plate to cause the problem of over-heating erosion to occur because of frequent or improper operation, in Fig. 3, the end faces forming the sides of this continuous undulating teeth groove 2151 and the continuous undulating double wedge 2121 of this output member 212 due to this tooth cover 215 are the plane perpendicular to this first axle 210, therefore when this tooth cover 215 forms the end contact of the side of this teeth groove 2151 and the double wedge 2121 of this output member 212, the smooth engagement in forming surface and face, simultaneously, because the end face of this double wedge 2121 and the jointing place of sidewall are roundings, so that this double wedge 2121 engages this teeth groove 2151, exert pressure by shift fork at this output member 212, and under the state that this input component 211 and this output member 212 are in rotation, thus this double wedge 2121 is made to be able to slip into this teeth groove 2151 by this input component 211 and the speed discrepancy of this output member 212, therefore in the process engaged with this teeth groove 2151 at this double wedge 2121, without the need to reducing the revolution of too much this input component 211, the transmission of power can be completed, thus avoid producing the gear rattle sound as in prior art during the contact of dog synchronizer, in Fig. 8 to Figure 10, the canine tooth side of third gear, fourth speed and fifth speed gear is respectively the tooth cover 3251 of tooth cover the 3151, the 3rd synchronizer of the first synchronizer and the tooth cover 3351 of the 5th synchronizer engaged, therefore gearbox of the present invention can by the clutch of control first speed regulator 21, second speed regulator 22 and the 3rd speed regulator 23 rapidly by third gear upshift to fifth speed, because gearbox of the present invention is except first grade and the 11 grade, the dog synchronizer of its adjacent front and back two gear of remaining each gear all engages in advance, if therefore run into emergency situations when need downshift at once in the process upshiftd, can downshift rapidly by the clutch of control first speed regulator 21, second speed regulator 22 and the 3rd speed regulator 23, when gearbox is reverse gear, the tooth cover 3151 of the first synchronizer 315 moves the canine tooth side of engaging reverse gear 311 by the operation of the shift fork of power mechanism control to the front end of this speed change gear room 30, first speed regulator 21 engages by the operation of the shift fork F of power mechanism control simultaneously, now the power of engine 10 is passed to output member 212 and first live axle 310 of the first speed regulator 21 via input shaft 110 and actuation gear 11, drive via reverse gear 311 and idlely take turns 351, then form reverse gear by idle first gear 341 of taking turns 351 driver output axles 340 and export, shift fork mentioned by the present invention is the shifting fork mechanism of additional hydraulic or electric actuator in prior art.

The above is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, not departing from the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
