Specific implementation mode
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
The every other embodiment that field those of ordinary skill is obtained without making creative work, belongs to this practicality
Novel protected range.
Referring to FIG. 1, Fig. 1 is a kind of decomposition of specific implementation mode of linked transmission system provided by the utility model
Figure.
In a specific embodiment, linked transmission system provided by the utility model is used for the vehicle of chain driving
In, which can be bicycle, motorcycle, electric vehicle or electric booster bicycle etc., and the present embodiment is by taking shared bicycle as an example.
The linked transmission system includes preceding chain wheel 1, rear chain wheel 2, is sequentially connected in the chain 3 of two chain wheels, and on vehicle frame
Protective acoustic cover assembly and the chain device 6 that rises in the protective acoustic cover assembly, the chain device 6 that rises are installed on vehicle frame and for adjusting institute
State the rate of tension of chain 3.In ride, the chain device 6 that rises can adjust rate of tension at any time according to the current tightness of chain, with
Just chain 3 is in tensioning degree appropriate always.
Wherein, the protective acoustic cover assembly includes chain guard 4 and the chain cover being removably interlocked with the chain guard 45, the chain
Cover 4 forms accommodating cavity when being in buckling state with the chain cover 5, and preceding chain wheel 1, rear chain wheel 2, chain 3 and the chain device 6 that rises are respectively provided with
In in the accommodating cavity, it is in so as to each functor in the enclosure space of protective acoustic cover assembly, improves protective capacities, avoid correlation
Functor is damaged.Alternatively it is also possible to which the chain device 6 that rises only to be integrated in the inside of protective acoustic cover assembly, front and back chain wheel or part
Chain can need to be arranged except protective acoustic cover assembly according to service condition and protection.
The above-mentioned chain device 6 that rises can be fixed on Rear Ends/Dropouts on piece or be fixed on other appropriate locations of vehicle frame.Specifically, rise chain
Device 6 includes mounting base and the expansion tightening wheel that is set in the mounting base, the expansion tightening wheel by spring be installed on the mounting base,
And the chain is lifted under the action of the spring, the mounting base is removably secured with the chain guard 4 and connect, and passes through peace
Dress seat is fixed in back vent dististyle, to improve installation convenience；In ride, if chain is excessively loose, spring discharges elastic force and but
The direction that dynamic expansion tightening wheel is tensed to chain moves, until when chain tension reaches preset value, torque that chain applies to expansion tightening wheel
It is equal with the torque that spring applies to expansion tightening wheel, so that expansion tightening wheel fixation is motionless in the position；And if chain tension, bullet
The active force pushing that spring applies in chain contracts while generating moment shell, and chain is moved to the direction loosened therewith, until chain
When tightness reaches preset value, also due to the torque that chain and spring generate reaches balance on expansion tightening wheel so that expansion tightening wheel is solid
It is fixed motionless in the position, and then realize the instant adjustment of chain tension.Mounting base and the detachable connection of chain guard 4 can
Think and the forms such as is bolted or snaps connection.
Above-mentioned mounting base includes the main part for installing the expansion tightening wheel, and is set to the installation of the main part side
Ear, the mounting ear are detachably connected with the back vent dististyle.Detachable connection between mounting ear and back vent dististyle can
Think and the forms such as is bolted or snaps connection.
Chain guard 4 is preferably fixed using snap fit with chain cover 5, and specifically, the chain guard 4 is provided with the first installation crimp,
Clamping block is installed, the chain cover 5 is provided with the second installation crimp, and described second installs on crimp on the first installation crimp
