Embodiment
Core of the present utility model is to provide a kind of transmission device of double-clutch speed changer, and this transmission device can extend the operating life of double-clutch speed changer.Another core of the present utility model is to provide a kind of double-clutch speed changer that comprises above-mentioned transmission device.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 1, the utility model embodiment provides a kind of transmission device of double-clutch speed changer, and this transmission device comprises output shaft 11, is set with reverse idler gear 12 and other component on this output shaft 11.One of key improvements point of above-mentioned transmission device is, at least one side of reverse idler gear 12 is provided with push stopping part, this push stopping part is set on output shaft 11, and the end face of one side surface and reverse idler gear 12 fits, and opposite side surface fits on the parts adjacent with reverse idler gear 12.Said " parts adjacent with reverse idler gear 12 " can be that synchronizer 13 or the output shaft master who is set on output shaft 11 subtracts gear 14 herein, or miscellaneous part.
Particularly, can only between reverse idler gear 12 and synchronizer 13, push stopping part be set, also can be only subtract between gear 14 push stopping part is set reverse idler gear 12 and output shaft master.In addition, the structure of push stopping part can be thrust washer or other structures, as long as push stopping part can stop reverse idler gear 12 to be tumbled.
When above-mentioned transmission device work, reverse idler gear 12 is subject to after tilting moment, can intercept reverse idler gear 12 and miscellaneous part by push stopping part, stops tumbling of reverse idler gear 12 with this, and then prevents that reverse idler gear 12 and other parts on output shaft 11 from colliding.Obviously, than the content of introducing in background technique, the transmission device that the utility model embodiment provides can be alleviated the wearing and tearing between reverse idler gear 12 and miscellaneous part, and then extends the operating life of transmission device.
Further, reverse idler gear 12 subtracts between gear 14 at synchronizer 13 and output shaft master, and the both sides of reverse idler gear 12 are respectively arranged with the first push stopping part and the second push stopping part, the first push stopping part is arranged between reverse idler gear 12 and synchronizer 13, and the second push stopping part is arranged at reverse idler gear 12 and output shaft master subtracts between gear 14.This scheme all arranges thrust structure in the both sides of reverse idler gear 12, thereby prevents that more reliably reverse idler gear 12 from tumbling.
In order to alleviate the wearing and tearing between push stopping part and reverse idler gear 12, aforesaid the first push stopping part can comprise the first sliding bearing 15, and the end face of the side of this first sliding bearing 15 and synchronizer 13 fits.In like manner, the second push stopping part also can comprise the second sliding bearing 16, and the end face that this second sliding bearing 16 can subtract gear 14 with output shaft master fits.Further, the manufactured materials of the first sliding bearing 15 and the second sliding bearing 16 all can adopt PEEK (Polyether Ether Ketone, polyether-ether-ketone) resin, this material has the following advantages: 1) friction factor is low, and work of slipping is smaller; 2) there is certain self lubricity, can under unlubricated condition, work, at high temperature there is certain lubricating ability; 3) there is the ability that contains foreign matter, be difficult for scratch fitting surface; 4) anti-attrition and wear resistance are relatively good, reduce the frictional heat of reverse idler gear 12 end faces, and load can withstand shocks; 5) to mould Dai Gang, cost is low, and structural design is simple, flexible, convenient.
In another embodiment, the second push stopping part can comprise the second sliding bearing 16 and L-type thrust washer 17, the end face of the side of the second sliding bearing 16 and reverse idler gear 12 fits, the L-type internal surface of L-type thrust washer 17 and the second sliding bearing 16 fit, the outer surface of L-type thrust washer 17 and output shaft master subtract gear 14 and fit, and locate L-type thrust washer 17 with this.By the combination of the second sliding bearing and L-type thrust washer 17, make that reverse idler gear 12 is more difficult tumbles, and wearing and tearing between each component are less.
As shown in Figure 2, in preferred technological scheme, on L-type thrust washer 17, subtract on the outer surface that gear 14 fits and have oil groove 171 with output shaft master, this oil groove 171 radially runs through L-type thrust washer 17 along output shaft 11.When transmission device work, lubricant oil can flow into L-type thrust washer 17 and output shaft master subtracts the fitting surface between gear 14 from oil groove 171, and then forms effective and continuous lubricant film, takes away frictional heat, thereby provide lubricated to both relative movement, make wearing and tearing between the two less.
Particularly, the quantity of above-mentioned oil groove 171 can be only one, and the utility model embodiment is set to oil groove 171 multiple, and multiple oil groove 171 is along being circumferentially arranged of L-type thrust washer 17, and optimizes the greasy property of L-type thrust washer 17 with this.
For under the prerequisite of normal work that ensures the second push stopping part, reduce the area of contact between L-type thrust washer 17 and reverse idler gear 12 as far as possible, alleviate wearing and tearing between the two with this, between L-type thrust washer 17 and reverse idler gear 12, along output shaft 11 axially and output shaft 11 radially all there is gap, L-type thrust washer 17 does not contact with reverse idler gear.
As shown in Figure 3, more preferably, have oil groove 121 on reverse idler gear 12 with push stopping part on the end face fitting, this oil groove 121 is along the radially perforation of output shaft 11.After so arranging, the lubricant oil splashing can flow on the fitting surface between reverse idler gear 12 and push stopping part by oil groove 121, and then provides good cooperation for motion between the two.
The double-clutch speed changer that the utility model embodiment provides comprises transmission device, and this transmission device is the described transmission device of above-mentioned arbitrary technological scheme.Because above-mentioned transmission device has above-mentioned technique effect, the double-clutch speed changer that comprises this transmission device also should have corresponding technique effect, repeats no more herein.
Only by the mode of explanation, some example embodiment of the present utility model is described above, undoubtedly, for those of ordinary skill in the art, in the situation that not departing from spirit and scope of the present utility model, can revise described embodiment by various mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claim protection domain.
