Abstract
The present invention relates to a non-impact speed changing transmission gear which is composed of a tooth ring and a wheel hub, wherein the tooth ring is connected with the wheel hub through a tooth inlaid type normal engaging mechanism with elasticity gaps, the tooth ring and the wheel hub are connected with each other through a clamping plate to make axial limitation, and the clamping plate is fixed on the tooth ring. Furthermore, the tooth inlaid type engaging mechanism with elasticity gaps is concretely separated as follows: engaging gaps are arranged between engaging teeth connecting the tooth ring and the wheel hub, the engaging teeth of the wheel hub are positioned in the middle position of the gaps under the state of no torsion transmission by an elastic element to form an elastic gap type structure, and an inner hole of the wheel hub is an inner integral key hole or an unthreaded hole with key grooves. The non-impact speed changing transmission gear has the advantages of simple structure, simple manufacturing process and simple equipment. Besides, the non-impact speed changing transmission gear can not only achieve the portable and rapid gearshift of a synchronizer, but also eliminate the phenomena of inconvenient operation, low gearshift speed and impact and noise generation when a gear enters for engagement existing in a speed changer without the synchronizer; the non-impact speed changing transmission gear not only can be used for a duplicate gear, but also can be used for a simplex gear. Besides, the non-impact speed changing transmission gear can be widely used for speed changers of various vehicle models.
Description
Technical field
The present invention relates to a kind ofly can directly mesh the non-impact speed changing transmission gear of gear shift.
Background technique
The gear shift mode of existing transmission for vehicles has two kinds: a kind of is the speed changer of no synchronizer, simple in structure, but requires skilled operation during gear shift, and speed change is slow, easily produces between cog impact and noise; Another kind is the speed changer that synchronizer is arranged, though solved the shortcoming that the speed changer of no synchronizer exists, has complex structure, and manufacture process requirement height, the between centers size that takes up room is big, in the use friction element easy to wear wait not enough.The shortcoming and defect of above-mentioned two kinds of speed changers brings some inconvenience with unfavorable to manufacturing enterprise and user.
Summary of the invention
The present invention is directed to the deficiency that existing speed changer exists, synchronizer is cancelled, take a kind of novel non-impact speed changing transmission gear, realize and the equal function of synchronizer, reach light in the time of to guarantee shifting of transmission, rapid, do not have impact, muting requirement, can satisfy stable performance, long-lived requirement again.
For this reason, technological scheme of the present invention is: a kind of non-impact speed changing transmission gear is characterized in that: be made up of ring gear and wheel hub; Ring gear is connected with the castellated normal engaging mechanism of wheel hub by elastic gap, and ring gear is connected by clamping plate with wheel hub makes axial limiting, and clamping plate are fixed on the ring gear; The castellated normal engaging mechanism of described elastic gap specifically is decomposed into: be provided with the back lash between the engaging tooth of ring gear and wheel hub connection, make engaging tooth on the wheel hub under the state of transmitting torque not, be in the neutral position in gap with elastic element, form a kind of elastic gap formula structure; The endoporus of described wheel hub is inner splined hole or the unthreaded hole that has keyway; The side of wheel hub is provided with the annular groove of card shift fork, non-impact speed changing transmission gear is moved on back shaft realize speed-change and gearshift.
Working principle: this non-impact speed changing transmission gear can all use on main passive tooth realizes speed-change and gearshift, also can be only with one in the gear pair of speed-change and gearshift.When using this driving gear, under the promotion of shift fork, active and passive gear enters contact during speed change, and shift fork thrust produces a tangential component on two increments contact inclined-plane, this masterpiece is used in and overcomes spring force on the ring gear and make camber of spring, this moment, elastic gap worked, and ring gear just rotates along circumference of hub, and disappearing until one side angle of clearance is zero, the another side gap increases and is twice, castellated structure enters normal engaged, and during this elastic gap changed, two gears had been finished engagement process.During speed change, shift fork is thrown off engaging gear once more, and the moment of torsion that tooth embedding mechanism transmits disappears, and ring gear is kept in the center under the effect of spring force, forms the elastic gap that both sides equate again, is in the standby condition of speed change next time.
Beneficial effect of the present invention: simple in structure, manufacturing process and equipment are simple, and axial dimension can reduce the weight and the axial space occupy-place of speed changer, can reach light, the fast slewing of synchronizer; The annular groove handsetting gear that is stuck in wheel hub by shift fork is shifted gears, and can eliminate operation inconvenience, the switching speed impact and the noise slow, that produce when gear enters engagement of the speed changer existence of no synchronizer; No rapid wear friction element, stable performance, reliability and durability; Both can be used for duplicate gear, also can be used for the simply connected gear; Not limited by the torque capacity of friction element, can be widely used in the speed changer of various vehicles.
