Abstract
An external reverse gear unit for the speed variator of motorcycle is composed of a case assemblage for changing the rotational direction of driven axle, a manipulating mechanism installed on case body for driving the driven axle to change its rotational direction, and a reverse gear controlling drive for controlling the said manipulating mechanism. It features that the reverse gear can only be performed at low gear position, that is, reverse gear position "I", resulting in higher safety.
Description
(1) technical field:
The present invention relates to a kind of reverse gear, particularly relate to a kind of external reverse gear unit that is widely used in the different displacements speed variator for motorcycle engine.
(2) background technology:
At present, the motor-tricycle that reverse gear is installed adopts the driving engine of countershaft lengthening, only in this way, could be enclosed within the countershaft of driving engine on the drive bevel gear of reverse gear and rotate, reverse gear is bolted on the driving engine with miniature simultaneously, behind the countershaft lengthening of driving engine,, cause reverse gear to throw off driving engine and produce abnormal sound even motor bearing is damaged because the reverse gear vibration easily makes the bolt stripped thread; Because thereby existing reverse gear is to be mounted on the horizontally slipping to realize that with the clutch of the finishing bevel gear cuter end face that is contained in coaxial two ends the commutation of axle, vehicle advance and retreat respectively of end face clutch on the driven shaft.Therefore, occur trip stop and out of supply easily, not only noise is big, and the correlated parts wearing and tearing are aggravated, all adopt sliding stirring inside and outside this in addition, do not establish sealing arrangement again, easily make lubricating oil along flowing out in power-transfer clutch, the axial play, in case oil leakage arrives to a certain degree, finishing bevel gear cuter just can move under unlubricated state, causes damage, and even more serious is that existing reverse gear has several D Drives that several reverse gears are just arranged, navigating mate is not noted slightly like this, just beyond thought traffic accident can take place.
(3) summary of the invention:
The object of the present invention is to provide and a kind ofly have only a low reverse gears, and reduce noise, prevent oil leak, can be widely used in the external reverse gear unit of different displacements speed variator for motorcycle engine.
Purpose of the present invention can reach by the following technical programs, that is: this external reverse gear unit of speed variator for motorcycle engine comprises that can change the casing assembly that driven shaft turns to, and its key is that is contained in a steering unit and a reverse gear Control Driver of controlling this steering unit that is used for ordering about the driven shaft commutation on the casing.
Comprise in the described casing assembly being contained on the master and slave moving axis and the finishing bevel gear cuter that is meshed and a spline clutch cover that is contained on the driven shaft that this spline clutch cover is provided with female splines, two is provided with male splines, and boss place in middle part is fluted; Two driven wheel of differentials that are contained on the driven shaft are equipped with one section female splines; By stirring the clutch of spline clutch cover and two driven wheel of differentials, realize the commutation function of driven shaft, realize the purpose of the advance and retreat of vehicle;
The described steering unit that is used to order about the driven shaft commutation declutch shift shaft is arranged and be contained in successively shift fork on this, taper sheath, spring, pin, and bearing be hinged and be stuck on the pin connecting rod and respectively with shift fork, the joining spline clutch cover of driven shaft;
The reverse gear controller of described control steering unit is by reverse gear control Driver Circuit and two the automatically controlled driving locating dowel pins of being made up of control gate circuit and power amplification circuit W and K switch.
According to the above-mentioned gear reversing device that assembles, its working process such as following:
Working process: when engine speed changer is in " I " when shelves, gear " I " signal is opened control and is driven electronic locating dowel pin with door through anti-phase amplification and move up.Skid off right groove, steering unit moves right declutch shift shaft, and compression spring drives and sails the spline clutch cover and mesh from the mantle tooth, realizes reversing.Meanwhile, taper sheath makes the K switch closure.Electronic locating dowel pin inserts left groove downwards, finishes up to reversing.When driving engine gear during at the II-V gear, " I " shelves signal is eliminated, the actuator outgoing current is 0, under the effect of spring, electronic locating dowel pin upwards shifts out left groove, and spring forces declutch shift shaft to be moved to the left, and electronic locating dowel pin inserts right groove, spline clutch cover and another driven wheel of differential engagement this moment, vehicle moves forward.
The present invention compared with prior art has the following advantages:
1. because in the casing assembly, all and position casing exterior is equipped with seal rubber sleeve, can effectively prevent the oil leak in the case, make interior each part of case be in good lubricating status in the course of the work, not only avoided the dry grinding phenomenon to take place, and the service life of having improved whole device significantly.
2. because drive bevel gear is provided with female splines, can directly be contained on the countershaft spline of driving engine, box bottom and vehicle frame plate combine as a whole in addition, not only can avoid in the prior art because countershaft is long, the Yi Sheng vibration, the easily deficiency of generation mechanical breakdown, and box bottom can change design with the need, so can be widely used in the speed variator for motorcycle engine of different displacements.
3. owing to only be provided with a low reverse gears, can prevent the traffic accident that is caused in the high speed gear reversing because of carelessness when navigating mate is moveed backward in the prior art effectively.
4. because the setting of spline clutch cover and two driven wheel of differential female spliness makes its clutch steady; Because the setting of electronic locating dowel pin makes it in working order down, has controlled the play of declutch shift shaft effectively, has avoided in the prior art out of supply, trip stop phenomenon that the end face clutch is brought, and the service life of having improved correlated parts.
