Abstract
The invention discloses a non-impact speed-change transmission gear wheel, which is formed by a tooth ring and a rim. Wherein, the tooth ring and the rim are connected via the tooth-embedded mesh device with flexible space; the tooth ring and the rim are axially limited via the clamp plates; the clamp plates are fixed on the tooth ring; said tooth-embedded mesh device comprises: mesh space between the mesh tooth that connecting the tooth ring and the rim; the flexible element can make the mesh tooth of rim at the middle of space while do not transmit torque to form a flexible space; the inner hole of rim is a inner-pattern key or a smooth hole with key groove. The invention has simple structure, which can avoid the lower shift speed, the impact and noise when meshing the gear wheels, while it can be used in duplicate gear or single gear wheel, or different speed changers.
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.
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, axial dimension can reduce the weight and the axial space occupy-place of speed changer, can reach light, the fast slewing of synchronizer, can eliminate again operation inconvenience, switching speed that the speed changer of no synchronizer exists slow, produce when gear enters engagement and impact and noise; 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.
Description of drawings
Fig. 1 is a structure sectional view of the present invention.
Fig. 2 is the side view of invention shown in Figure 1.
Embodiment
Non-impact speed changing transmission gear as shown in Figure 1, 2 is made up of ring gear 1 and wheel hub 2; Ring gear 1 is connected with the castellated normal engaging mechanism that wheel hub 2 is crossed elastic gap, and ring gear 1 is connected by clamping plate 5, clamping plate 6 usefulness screws 7 with wheel hub 2 makes axial limiting, and clamping plate 5,6 are fixed on the ring gear 1.
The castellated normal engaging mechanism of described elastic gap is specially: the castellated normal engaging mechanism of described elastic gap is specially: be provided with the back lash between the engaging tooth of ring gear 1 and wheel hub 2 connections, monolateral angle of clearance is α, 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.As shown in Figure 2, described elastic element is a leaf spring 3, and leaf spring 3 is connected on the ring gear 1 by screw 4, and the engaging tooth that hook formation just in time blocks wheel hub 2 is extended at leaf spring 3 two ends.As shown in Figure 1, 2, the engaging tooth of wheel hub 2 is provided with dashpot 2b; Dashpot 2b's is middle high, and two ends are low, and two inclined-planes are formed on the bottom of groove, so that the hook formation of leaf spring 3 in the embedded groove, is realized minimal deformation when distortion, cushions the stressed of leaf spring 3.
As shown in Figure 1, the endoporus of wheel hub 2 is inner splined hole 2c, and shift fork 8 is stuck in the annular groove of wheel hub 2 sides, non-impact speed changing transmission gear is moved on back shaft realize speed-change and gearshift.The endoporus of wheel hub 2 also can be the unthreaded hole of band keyway, and this is that non-impact speed changing transmission gear is fixed on the back shaft by wheel hub 2, is engaged with by the mobile of other gear, realizes speed-change and gearshift.
Claims (3)
1, 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.
