Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1
As depicted in figs. 1 and 2, the present embodiment comprises: Five-gear synchronizer ring gear 2, reversing-gear synchronizer ring gear 5, synchronizer gear sleeve 4 and the synchronizer key 3 be arranged in synchronizer gear sleeve 4, wherein: Five-gear synchronizer ring gear 2 and reversing-gear synchronizer ring gear 5 are socketed between five grades of driving tooths and third gear driving tooth 6 respectively, and synchronizer gear sleeve 4 is between Five-gear synchronizer ring gear 2 and reversing-gear synchronizer ring gear 5.
It is outside that described synchronizer gear sleeve 4 is socketed on synchromesh gear hub 8, and synchromesh gear hub 8 is arranged on input shaft 7.
The inner side of described reversing-gear synchronizer ring gear 5 is provided with the reverse gear conical surface 10, and corresponding third gear driving tooth 6 is provided with the reverse gear inverted cone face 9 contacted with it.
Described reverse gear inverted cone face 9 is smooth in conjunction with the tooth conical surface, and reverse gear cone of friction 10, under the impetus of slide block 3, contact presynchronization.
The outside of described reversing-gear synchronizer ring gear 5 is provided with for spacing plum angle 11, and after presynchronization completes, the groove on tooth cover 4 crosses the steel ball on slide block 3, and the Mei Jiao on tooth cover 4 pushes away plum angle 11, reaches synchro converter ring 5 and fits with reverse gear inverted cone face 9, synchronously.After synchronously completing, reversing-gear synchronizer ring gear 5 crossed by tooth cover 4, is linked into reverse gear.
Described Five-gear synchronizer ring gear 2 is provided with equally for spacing plum angle 11.
As shown in Figures 2 and 3, in the present embodiment five grades, reverse gear shares a set of synchronizer, hang after a stoppage in reverse gear process: reverse idler gear 1 and synchronizer gear sleeve 4 link under reverse gear mechanism effect, under the friction in the reverse gear conical surface 10 and reverse gear inverted cone face 9, synchronizer gear sleeve 4, synchromesh gear hub 8, input shaft 7 realize synchronous with third gear driving tooth 6, speed reduces to zero, synchronizer gear sleeve 4 crosses the plum angle 11 of reversing-gear synchronizer ring gear 5 smoothly, reverse idler gear 1 engages with reverse gear driving tooth 12 smoothly, hangs reverse gear and completes.
Operating mechanism drives synchronizer gear sleeve 4 to promote reversing-gear synchronizer ring gear 5 and the reverse gear inverted cone face 10 phase friction on third gear driving tooth 6, to reach the object of falling input end rotating speed.
After input shaft 7 rotating speed is synchronous with third gear driving tooth 6, rotating speed reduces to zero, synchronizer gear sleeve 4 crosses reversing-gear synchronizer ring gear 5, reverse gear control mechanism continues to drive reverse idler gear 1 to engage with active, driven tooth, now, reversing-gear synchronizer ring gear 5 empty set, on reverse gear inverted cone face 10, does not affect third gear driving tooth 6 and rotates.
The present embodiment utilizes existing third gear driving tooth parking rotating speed to be zero, input shaft reduction of speed when achieving parking reverse gear, and when making reverse gear, three gears engage smoothly, solve longitudinal structure speed changer and hang reverse gear impulsive sound, hang the problems such as reverse gear has some setbacks.This design does not need to newly increase special reverse gear mechanism, existing similar speed changer is changed, just can obtain this reverse synchronizing device.
