Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 2, Fig. 3 and Fig. 6, automobile speed variator reverse gear mechanism of the present utility model, comprises; Reverse shaft 5; Be assemblied in the input shaft 1 on mission case by bearing of input shaft 32 and be assemblied in input shaft one grade of gear 2 on input shaft 1 from left to right, input shaft reverse gear 4, input shaft intermediate gear 6, input shaft five grades of gears 31, Five-gear synchronizer 30, input shaft three keep off gear 29 and three fourth gear synchronizers 28; Two ends are assemblied in the jack shaft 8 on mission case by jack shaft fore bearing 33 and jack shaft rear bearing 24 and are assemblied in jack shaft one grade of gear 12, second gear synchronizer 11, secondary gear of intermediate shaft 9, counter 5th gear 21, third-speed gear of intermediate shaft 22 and the jack shaft driving gear 23 on jack shaft 8 from left to right, and are assemblied in the countershaft reverse gear 10 on jack shaft 8; Be assemblied in the output shaft 7 on mission case by rear bearing, output shaft 25, front bearing, output shaft 26, be assemblied in the output shaft driving gear 27 on output shaft 7, described output shaft driving gear 27 engages with the jack shaft driving gear 23 on jack shaft 8; Described input shaft reverse gear 4 engages with the idler gear 3 that reverses gear.From Fig. 2, Fig. 3 and Fig. 6, the utility model also comprises reverse gear synchronizer 13, reverse shaft pad 14, reverse gear shaft fore bearing 15, reverse gear shaft rear bearing 16, reverse gear needle bearing 19 and reverse gear 50; Described reverse shaft 5 is assemblied between reverse gear shaft fore bearing 15 and reverse gear shaft rear bearing 16, and described reverse gear shaft fore bearing 15 is connected with mission case with reverse gear shaft rear bearing 16; Described reverse shaft pad 14, reverse gear needle bearing 19, reverse gear synchronizer 13 and reverse gear 50 are assemblied on reverse shaft 5 from left to right; Described idler gear 3 gap of reversing gear is assemblied on reverse gear needle bearing 19; Described reverse gear synchronizer 13 can move axially and can be meshed with the idler gear 3 that reverses gear; Described countershaft reverse gear 10 is between secondary gear of intermediate shaft 9 and counter 5th gear 21 and be meshed with the reverse gear 50 on reverse shaft 5.So, the tooth axle 50 that reverses gear no matter whether hanging the described reverse shaft 5 that reverses gear all is in engage fills state with countershaft reverse gear 10, idler gear 3 and the input shaft one grade of gear 2 that reverses gear.Therefore there will not be because gear slippage cause beat tooth problem.When extension reverses gear, although input shaft 1 still rotates due to effect of inertia, but under the effect of reverse gear synchronizer 13, input shaft 1 can be reached synchronous (geo-stationary) with the rotary speed of reverse gear 50 rapidly, thus prior art can be avoided to produce when extension reverses gear with input shaft reverse gear 4 clash into without reverse gear synchronizer 13 idler gear 3 that causes reversing gear, beat tooth, and be badly damaged, cause the gearshift difficult problem that reverses gear, even cause inefficacy of reversing gear, reduce the working life of speed changer, even cause security incident.
Described reverse gear 50 is structure as a whole with reverse shaft 5.This makes the one machine shaping with comparalive ease of reverse gear 50 and reverse shaft 5 and integral rigidity is better.
As seen from Figure 6, the idler gear 3 that reverses gear described in the utility model is provided with the idler gear gear ring 3-1 that reverses gear with its one, reverse gear idler gear conical surface 3-2, described reverse gear synchronizer 13 comprises reverse gear synchronizer ring gear 13-1, reverse gear synchronizer slide block 13-4, reverse gear synchronizer tooth cover 13-3 and reverse gear synchronizer tooth shell 13-5, described reverse gear synchronizer ring gear 13-1 is provided with the ring gear keyway 13-2 that reverses gear, what described reverse gear synchronizer ring gear 13-1 gap was set in idler gear 3 right-hand member that reverses gear reverses gear on idler gear conical surface 3-2, described reverse gear synchronizer 13 can move axially and be meshed with the idler gear gear ring 3-1 that reverses gear of the idler gear 3 that reverses gear by its reverse gear synchronizer tooth cover 13-3.This makes reverse gear synchronizer 13 to move axially and can be meshed preferably with the idler gear 3 that reverses gear.
Described input shaft one grade of gear 2, input shaft reverse gear 4 and reverse gear 50 are dextrorotation helical gear, and accordingly, institute's idler gear that reverses gear 3 and countershaft reverse gear 10 are left-hand helical gear.This makes reverse gear 50 contrary with the rotation direction of reversed gear idler gear 3, suffered axial force can part be cancelled out each other, thus reduce reverse gear shaft fore bearing 15 and the bearing capacity suffered by reverse gear shaft rear bearing 16, improve the working life of reverse gear shaft fore bearing 15 and reverse gear shaft rear bearing 16.
Described input shaft reverse gear 4 and input shaft one grade of gear 2 are structure as a whole.This makes the one machine shaping with comparalive ease of input shaft reverse gear 4 and input shaft one grade of gear 2 and integral rigidity is better.
Working principle of the present utility model is as follows;
See Fig. 4, when forward gears hung by speed changer, reverse gear idler gear 3 and input shaft reverse gear 4(input shaft one grade of gear 2) engagement, reverse gear 50 engages with countershaft reverse gear 10: the one grade of gear 2 of the input shaft now on input shaft 1, input shaft intermediate gear 6, input shaft three-range transmission 29, jack shaft one grade of gear 12 on input shaft five grades of gears 31 and jack shaft 8, secondary gear of intermediate shaft 10, third-speed gear of intermediate shaft 22, counter 5th gear 21 engages, sense of rotation is contrary, on jack shaft 8, on jack shaft driving gear 23 and output shaft 7, output shaft driving gear 27 engagement makes sense of rotation again reverse, input, the sense of rotation exported is consistent, namely input shaft fixed thereon one grade of gear 2, the sense of rotation of countershaft reverse gear 10 is different, thus make the idler gear 3 that reverses gear that engages with it, reverse shaft 5 rotates backward, now reverse gear mechanism not transferring power, belong to idle running.
See Fig. 6, when speed changer extension reverses gear, the reverse gear synchronizer tooth cover 13-3 of reverse gear synchronizer 13 slides to the idler gear 3 that reverses gear under the effect of back fork 17, in this process, reverse gear synchronizer tooth cover 13-3 drives reverse gear synchronizer slide block 13-4 extruding reverse gear synchronizer ring gear 13-1 to make it rub with the conical surface 3-2 of the idler gear 3 that reverses gear, this frictional force make to reverse gear rotating speed of idler gear 3 is identical with the rotating speed of reverse gear synchronizer 13 (namely synchronous, after synchronous, gearshift can effectively avoid gearshift to beat tooth sound) after, the tooth cover 13-3 of reverse gear synchronizer 13 engages with the gear ring 34 of the idler gear 3 that reverses gear.
See Fig. 5, during transmission reverse gear, engage with the gear ring of the idler gear 3 that reverses gear on the left of the tooth cover 13-3 of reverse gear synchronizer 13, right side is connected with the external splines of the tooth shell 13-5 of reverse gear synchronizer 13, because reverse gear synchronizer tooth shell 13-5 is fixed on reverse shaft 5 with spline form, so now reverse gear, idler gear 3 and reverse shaft 5 rotating in same direction transferring power, realize gear reversing function.
See Fig. 4, Fig. 5 and Fig. 6, power transmission line of the present utility model and axle tooth spiral veer as follows: input shaft 1(forward) → input shaft reverse gear 4(forward) → idler gear the 3(that reverses gear is reverse) 13-3(is reverse for → reverse gear synchronizer tooth cover) 13-5(is reverse for → reverse gear synchronizer tooth shell) → reverse shaft 5(is reverse) → reverse gear 50(is reverse) → countershaft reverse gear 10(forward) → jack shaft 8(forward) → jack shaft driving gear 23(forward) 27(is reverse for → output shaft driving gear) → output shaft 7(is reverse).
