Abstract
A reverse mechanism for motorcycle is composed of a drive shaft with drive chain gear and drive chain, a driven shaft with driven chain gear and driven chain, and a transmission chain between said two chains. One of both chain gears is keyed to relative shaft. Another one is sleeved on the relative shaft in movable mode. Said sleeved chain gear has the first linking structure (a hole) and its shifting gear has the second linking structure (jaw).
Description
Technical field
The present invention relates to a kind of reverse gear mechanism of motorcycle.
Background technology
The reverse gear mechanism of motorcycle that exists on market at present mainly contains two kinds: 1) external reverse gear mechanism: this mechanism places the casing outside, and mechanism's more complicated needs the parts of increase many, and needs to change the running part of car load; Cost is higher.Design aspect at structure, manufacturing, cost and car load all has limitation; 2) built-in reverse gear mechanism: generally all adopt the mode that increases carrier gear, this mode complex structure, the machine that needs to change casing adds size, is unfavorable for the exchange of casing, and cost is higher, because parts are also unfavorable to assembly technology too much.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of simple in structure, reequip easy, lower-cost reverse gear mechanism of motorcycle.
For achieving the above object, technical scheme of the present invention is: a kind of reverse gear mechanism of motorcycle, comprise imput shaft, driven shaft, and on described imput shaft, be provided with drive sprocket, driven shaft is provided with driven sprocket, is connected with driving chain between drive sprocket and the driven sprocket; Wherein drive sprocket is connected in imput shaft by key, and then movable set is in driven shaft for driven sprocket, and perhaps driven sprocket is connected in driven shaft by key, drive sprocket then movable set in imput shaft; The driven sprocket of this movable set or drive sprocket side are provided with first connection structure, and with the driven sprocket of movable set or drive sprocket is coaxial and be provided with and cooresponding second connection structure of described first connection structure with the axle key bonded assembly change gear side of its suit.
Described first connection structure can be at least two uniform connecting bores, and described second connection structure is for connecting pawl.Described connecting bore is respectively four with the quantity that is connected pawl.Described connection structure also can be other forms of connection structure, as profile of tooth connection structure etc.
1), simple in structure advantage of the present invention:, only need to increase a reverse gear chain, wherein a pair of gear changes and makes driving chain wheel and get final product; 2), need not change any position in the casing,, adorn that remaining is still passable if this casing is not adorned reverse gear mechanism; 3) annex is few, only increases a chain, and cost is lower, and mechanism is simple, and repacking easily.
Description of drawings
Fig. 1 is the constructional drawing of reverse gear mechanism of motorcycle of the present invention.
Fig. 2 is the left view of Fig. 1.
Among the figure
1. imput shaft 2. driven shafts 3. drive sprockets 4. driven sprockets
5. driving chain 6. connecting bores 7. connect pawl 8. change gears 9. splines
The specific embodiment
As shown in Figure 1, reverse gear mechanism of motorcycle of the present invention comprises imput shaft 1, driven shaft 1, is provided with drive sprocket 3 on described imput shaft 1, and driven shaft 2 is provided with driven sprocket 4, is connected with driving chain 5 between drive sprocket 3 and the driven sprocket 4; Wherein drive sprocket 3 is connected in imput shaft 1 by key, driven sprocket 4 then movable set in driven shaft 2; These driven sprocket 4 sides are provided with first connection structure, and are provided with and cooresponding second connection structure of described first connection structure with driven shaft 2 key bonded assembly change gears 8 sides.Certainly also can adopt driven sprocket to be connected in driven shaft by key, drive sprocket then movable set in the scheme of imput shaft; Be provided with first connection structure in the drive sprocket side this moment, and be provided with and cooresponding second connection structure of described first connection structure with active axle key bonded assembly change gear side.Described first connection structure is four uniform connecting bores 6, and described second connection structure is cooresponding four connection pawls 7.Described steering sprocket key is connected to spline 9 and connects, referring to Fig. 2.
1), the connection pawl 7 of change gear 8 enters in the connecting bore 6 of driven sprocket 4 referring to Fig. 1, the working process of this reverse gear mechanism of motorcycle is as follows:; 2) when imput shaft 1 is rotated, drive drive sprocket 3 and rotate together; 3), drive sprocket 3 drive driving chains 5 rotate together; 4), driving chain 5 drives driven sprocket 4 rotations; 5), because driven sprocket 4 is connected with driven shaft 2 splines with change gear 8, i.e. so rotation direction unanimity is the rotation of realization driven shaft; Reach the requirement of reverse gear.
Describe the present invention with way of example above, but the invention is not restricted to above-mentioned specific embodiment, all protection domains that any improvement that the present invention did or modification are all belonged to claim of the present invention.
