Abstract
The utility model relates to a reversing-gear synchronizer of a speed changer, which comprise a five-gear synchronizer, a reversing-gear synchronizing ring and a reversing-gear synchronizing cone, wherein the five-gear synchronizer is connected with an input shaft, and a group of convex lugs of the reversing-gear synchronizing cone is connected with a group of grooves of the speed changer, a casing of the speed changer is fixed to a hanging rack of a carriage underframe, and the reversing-gear synchronizing ring is arranged between the reversing-gear synchronizer and the reversing-gear synchronizing cone and is connected with the five-gear synchronizer. A friction surface of the lower end is connected in friction type with the reversing-gear synchronizing cone. The utility model overcomes the defects that gear reversing is difficult for without the five-gear synchronizer, the camber angles of the tooth tips of reversing-gear gears are easy to be worn and sound the squealing for friction and colliding among them. The reversing-gear synchronizing cone is independent of the structure of the casing of the speed changer, and the integral manufacturability is good.
Description
Technical field the utility model patent relates to a kind of reverse gear synchronizer of car gear shifting speed changer
The traditional speed changer of background technique is owing to reasons such as structural configuration, generally do not arrange Five-gear synchronizer, do not have under the situation that manual transmission is static at car and input shaft does not change of Five-gear synchronizer, the extension reverse gear is reliable, but often change reverse gear under the situation that input shaft does not stop operating fully, produce like this that reverse gear is difficult hangs, and in the engage a gear process because mutual friction mutually between the increment cusped arch angle of reverse idler gear and input shaft reverse gear, and the increment damage occurs and follow the phenomenon of shriek.
The summary of the invention the purpose of this utility model is to solve that reverse gear is difficult hangs, eliminates in the gearshift procedure, because the increment cusped arch angle of reverse idler gear and the input shaft reverse gear problem of mutual friction mutually, and a kind of reverse gear synchronizer is provided.
The utility model takes following technological scheme to realize purpose of the present invention, it comprises that Five-gear synchronizer, reverse gear are bored synchronously, the reverse gear synchronizing ring, Five-gear synchronizer is connected on the input shaft, reverse gear is bored excircle synchronously has one group of evagination lug to connect with corresponding one group of groove fit of case of transmission, case of transmission is fixed on the carriage underframe suspension, the reverse gear synchronizing ring is arranged between Five-gear synchronizer and the synchronous awl of reverse gear, be connected with five retaining synchromesh gear hubs, the rubbing surface of lower end is connected with the awl friction with reverse gear.
The utility model type Five-gear synchronizer and former Five-gear synchronizer share, reverse gear is bored synchronously and is connected static case of transmission, its one group of lug connects with one group of groove of case of transmission, by the Five-gear synchronizer synchronous effect, input shaft is remained static, avoid not having difficult extension of speed variator reverse gear of reverse gear synchronizer, wipe between the crown arch angle of reverse gear and bump rapid wear and shriek, improve speed changer and change the reverse gear performance.Reverse gear is bored the structure that is independent of case of transmission synchronously, easily processing, and integrated artistic is good.
Description of drawings Fig. 1 structural layout plan.
Fig. 2 is that the H-H of Fig. 1 is to view.
The 1-input shaft, the 2-Five-gear synchronizer, the 3-case of transmission, 4-reverse gear synchronizing ring, the 5-reverse gear is bored synchronously
Embodiment is consulted Fig. 1 and Fig. 2, Five-gear synchronizer 2 of the present utility model (share with former Five-gear synchronizer) is connected with input shaft 1 spline, reverse gear has one group three to protrude lug and 3 one groups of three corresponding groove fit connections of case of transmission outward on awl 5 excircles synchronously, realize that the synchronous awl 5 of reverse gear cooperates with case of transmission 3 centering, reverse gear synchronizing ring 4 is arranged in Five-gear synchronizer 2 and reverse gear is bored between 5 synchronously, it and Five-gear synchronizer 2 tooth hubs flexibly connect, and its lower end rubbing surface is bored 5 conical surface frictions synchronously with reverse gear and is connected.Operating handle drives Five-gear synchronizer 2 teeth cover and moves awl 5 aspects synchronously toward reverse gear, the rubbing surface that at first is reverse gear synchronizing ring 4 contacts with the conical surface of the synchronous awl 5 of reverse gear, realize that reverse gear synchronizing ring 4 is connected with awl 5 frictions synchronously of retaining shelves, reverse gear awl 5 synchronously is connected on the case of transmission 3, case of transmission 3 is to be fixed on the chassis suspension of car, remains static.By Five-gear synchronizer 2 synchronous effects, input shaft 1 is remained static.Guarantee that reverse idler gear just contacts with input shaft 1 reverse gear end face after Five-gear synchronizer 2 reaches synchronously, realized gearshift mechanism drive reverse idler gear and before reverse gear contacted, input shaft 1 had remained static.Avoided traditional speed changer can not solve extension by Five-gear synchronizer 2 guarantees the defective that input shaft is static, has improved the engage a gear performance of speed changer at all when reversing gear.
