Abstract
The utility model relates to a motorcycle reverse gear mechanism, which comprise a driving shaft and a driven shaft. The driving shaft is provided with a driving chain wheel, and the driven shaft with a driven chain wheel. The driving and driven chain wheels are connected with each other through a transmission chain; the driving chain wheel is connected with the driving shaft through a key, and the driven chain wheel is connected with the driven shaft actively; or the driven chain wheel is connected with the driven shaft through a key, and the driving chain wheel is connected with the driving shaft actively; the side of the driving chain wheel or driven chain wheel is provided with a first connection structure, and the side of a shift gear connected with the shaft key and of the same shaft with the driven chain wheel or the driving chain wheel is provided with a second connection structure corresponding with the first connection structure. The first connection structure can be a connection hole, and the second connection structure a connection claw. The reverse gear mechanism, with simple structure and few spare parts, just needs to add a chain and change a gear wheel into a transmission chain wheel. Therefore, the utility model has the advantages of low cost and easy face-lifting.
Description
Technical field
The utility model relates to a kind of motor bike reverse gear mechanism.
Background technology
The motor bike reverse gear mechanism 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) reverse gear embedded 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.
The utility model content
The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, reequips easy, lower-cost motor bike reverse gear mechanism.
For achieving the above object, the technical solution of the utility model is: a kind of motor bike reverse gear mechanism, 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 power shift 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 utility model:, only need to increase the chain that reverses gear, 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 the utility model motor bike reverse gear mechanism.
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 chains 6. connecting bores 7. connect pawl 8. power shift gears 9. splines
The specific embodiment
As shown in Figure 1, motor bike reverse gear mechanism of the present utility model 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 power shift 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 power shift gear 8 enters in the connecting bore 6 of driven sprocket 4 referring to Fig. 1, the working process of this motor bike reverse gear mechanism 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 reversing gear.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment the protection domain that all any improvement that the utility model is done or modification all belong to the utility model claim.
Claims (4)
