Description
Technical field
The utility model relates to a kind of automobile multistage gear-driving speed-variable device.
Background technique
Automotive transmission commonly used at present comprises casing, input shaft, output shaft, jack shaft, several gear pairs and synchronizer and release bearing operating mechanism.Input shaft is the axle tooth, imports as power.Several gears that can pivot are arranged on the output shaft, export as power; Input the tip of the axis dress needle bearing, needle bearing are packed in the output shaft stomidium, and input shaft and output shaft are on same axis but do not connect mutually.The axis of jack shaft and the parallel axes of input and output shaft.Casing adopts integrated type and branch mailbox up and down more, and the processing technology complexity is cleaned inconveniently, and assembly process process is poor.The tooth hub of synchronizer is contained between output shaft two adjacent teeth wheel, and synchronizer sleeve can engage, separate under the shift fork effect with the synchronous gear ring of adjacent gear.Synchronizer is distributed on the same axle, and this load strengthens, and causes the diameter of axle to increase, and centre distance strengthens, and synchronizing capacity descends, and the weight of speed changer integral body increases, and handles degree of comfort decreased.Present common mechanical type step change transmission, its release bearing actuating element is made up of release bearing, jump ring, disengaging yoke axle assembly, torsion spring assembly, separation force is transmitted as follows: Separating force passes to release bearing by the disengaging yoke axle assembly and makes the torsion spring distortion, when Separating force is cancelled, set aside back release bearing and disengaging yoke axle assembly in the restoring force effect of torsion spring, get back to initial position, release bearing becomes point to contact with the disengaging yoke axle assembly, this makes the release bearing discontinuity, clutch is not steady, and shorten working life.
Summary of the invention
The purpose of this utility model is to provide that the processing of a kind of casing is simple, compact structure, complete machine is small and exquisite, transmission efficiency is high, complete synchronously, clutch mechanical synchronous transmission stably.
The purpose of this utility model can reach by the following technical programs, that is: this mechanical synchronous transmission comprises casing, slip minor axis, input shaft assembly, output shaft assembly, intermediate shaft assembly, bearing, reverse shift fork and synchronizer, and its key is: casing by before, during and after three sections form; First and second synchronizer is arranged in respectively on input shaft, the jack shaft between the two adjacent vacant cover constant mesh gear, by reverse shift fork the engagement cover is axially slided, under the effect of slide block, synchronizing ring, respectively with input shaft on two adjacent constant mesh gears synchronously in conjunction with gear ring in conjunction with, separate; The 3rd synchronizer is arranged on the input shaft and combines with output shaft, by reverse shift fork engagement cover axially slided, under the effect of slide block, synchronizing ring, with constant mesh gear on the output shaft synchronously in conjunction with the gear ring engagement, separate; The clutch operating fork plate becomes lever arrangement in preceding casing, and release bearing connects with the clutch operating fork plate by spring, and is sleeved on the casing axle journal, and return spring one end is connected on the clutch operating fork plate, and an end is connected in preceding cabinets cavity; The clutch operating fork plate rotates combination, the separation that realizes clutch around separating support fixation point under the effect of combination, Separating force.
Have synchronously in conjunction with gear ring in the described constant mesh gear.
Described synchronizer all has tooth hub, engagement cover, slide block, spring and synchronizing ring; And second synchronizer sleeve has external toothing.
The utility model mechanical synchronous transmission is compared with speed changer commonly used, a synchronizer is contained on the jack shaft, passed through once increase turn round outside, all the other two synchronizers all are arranged on the input shaft and do not turn round through increasing, reduce the wearing and tearing and the automatic possibility out of supply of shift component, can shorten lock in time again, alleviate berth-changing strength, gear shift is flexible.Rearmounted axle, gear and the synchronizer structure of making of normal engagement driving gear is compact light and handy, and this distribution has reduced the transmission assembly volume, and speed changer weight is lighter, and more reasonable structure is compared with the speed changer of other identical central distance, can bear bigger moment of torsion.Back branch mailbox mode in before casing adopts, technology capability is good, cleans no blind chamber, guarantees the product turbidity test better, and assembly process process is good.During clutch,, compare, make clutch more steady, reliable, the longer service life of release bearing with using speed changer always because the clutch operating fork plate carries return spring and be that line contact with release bearing.
