Description
Technical field
The utility model relates to reversing-gear synchronizer, particularly relates to a kind of novel reversing-gear synchronizer for car gear shifting speed changer.
Background technique
Along with the development of automobile industry, the Design and manufacture of speed changer is also ripe gradually.Reverse gear, as the less gear of a relative application frequency, is the compactedness improving structural configuration, reduces axial distance and reduce costs, generally all selecting the scheme of not arranging reversing-gear synchronizer.When reversing-gear synchronizer do not arranged by speed changer, when vehicle stationary and input shaft do not turn, hang reverse gear ratio to be easier to, but hang reverse gear when input shaft does not stop operating, just seem very inconvenient, hang in reverse gear process reverse gear idle pulley and the mutual friction of output shaft reverse gear phase simultaneously, increment wearing and tearing and noise can be produced.
The existing speed changer structure arranging reversing-gear synchronizer is: reversing-gear synchronizer tooth hub and output shaft splined, reverse gear driven gear is sleeved on the needle bearing that output shaft installs, reverse gear driven gear and reverse gear are in conjunction with gear ring splined, synchronizer key installed by reversing-gear synchronizer tooth hub, and reverse gear is in conjunction with gear ring being set with reverse gear synchronizing ring.There is complex structure in existing reversing-gear synchronizer, the problem that axial length is large, difficulty of processing is large.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of novel reversing-gear synchronizer for car gear shifting speed changer is provided, its structural configuration is compact, axial distance is little, difficulty of processing and cost low, reverse gear difficulty can be solved hang simultaneously, eliminate the problem due to reverse idler gear and the mutual fricative parts depreciation of reverse gear and noise in reverse gear process.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of novel reversing-gear synchronizer for car gear shifting speed changer, comprise output shaft, it is characterized in that: on output shaft, be set with lining, lining is set with needle bearing, needle bearing is set with reverse gear driven gear, is set with reversing-gear synchronizer tooth cover reversing gear on driven gear, between reverse gear driven gear and reversing-gear synchronizer tooth overlap, is provided with synchronizer key, output shaft upper spline connects installs reverse gear in conjunction with gear ring, and reverse gear synchronizing ring is sleeved on reverse gear, and in conjunction with gear ring, the outer and conical surface is harmonious.
Advantage of the present utility model and beneficial effect are:
1, reversing-gear synchronizer for car gear shifting speed changer of the present utility model, reverse gear driven gear is arranged on output shaft by lining and needle bearing, reverse gear synchronizing ring is inserted in reverse gear in conjunction with on gear ring, reverse gear adopts splined in conjunction with gear ring and output shaft and jointly rotates, when hanging reverse gear, reversing-gear synchronizer tooth cover moves toward the rear end of speed changer vertically, reversing-gear synchronizer tooth cover and reverse gear synchronizing ring indented joint reach synchronous, reverse gear synchronizing ring and reverse gear in conjunction with gear ring by conical surface friction effect, output shaft rotating speed is made to be reduced to geo-stationary, reversing-gear synchronizer tooth cover and reverse gear engage gear ring indented joint and reach synchronous, when hanging reverse gear, operate slide block more steady, eliminate the problem due to reverse idler gear and the mutual fricative parts depreciation of reverse gear and noise in reverse gear process.
2, the reversing-gear synchronizer for car gear shifting speed changer of the present utility model, reverse gear driven gear and reversing-gear synchronizer tooth hub are combined into a part, the processing of output shaft external splines eliminating reversing-gear synchronizer tooth hub internal spline and be mated, eliminate simultaneously reverse gear driven gear external splines and be mated reversing-gear synchronizer tooth cover external splines processing, reduce difficulty of processing and processing cost, it also avoid reverse gear driven gear and the riveting that may occur when reversing gear and be connected in conjunction with gear ring and weld defects simultaneously.
3, the reversing-gear synchronizer for car gear shifting speed changer of the present utility model, eliminates the spline joint that reverse gear engages gear ring and reverse gear follower, shortens the axial dimension 8 ~ 10mm of speed changer, improve the compactedness of structural configuration; Decrease assembling link simultaneously, improve efficiency of assembling.
4, the utility model design science is reasonable, and structural configuration is compact, and axial distance is little, difficulty of processing and cost low, solve reverse gear difficulty and hang, eliminate the problem due to reverse idler gear and the mutual fricative parts depreciation of reverse gear and noise in reverse gear process.
