Description
Technical field
The present invention relates to a kind of sliding rail type rear speed changer, comprise that one affects part, a slide track seat and a sliding part; When speed change along with the change-speed box start, utilize the spring in sliding part and slide track seat, allow spring stress start or loosen involution, thereby driving idle pulley folder, make the chain that is engaged on idle pulley folder idle pulley at the Flywheel fluted disc top offset, the present invention is different from traditional cantilever linkage spring loaded Rear Derailleur, but the Rear Derailleur system of a kind of innovation, revolution.
Background technology
Traditional transmission system is mainly to utilize, pull the speed change cable and strain or loosen change-speed box, connecting rod and spring by the cantilevered Rear Derailleur, order about the movable rod displacement, make the chain that is engaged on the bitch chain steering wheel at the flywheel top offset to different Flywheel fluted discs, when the number of teeth gap of current deep bid and rear flywheel was fewer, required strength of trampling was less; Otherwise just need larger strength.
in the market, Rear Derailleur mainly uses the cantilever linkage spring loaded, mainly can be divided into forward and reverse change-speed box, so-called forward refers to, change-speed box not (while by the speed change cable, not pulled) during start, be provided with the movable rod position of bitch chain steering wheel, it is in minimum fluted disc (number of teeth the is minimum) position of flywheel, and when change-speed box start (volume draws the speed change cable), the shelves that advance along with the speed change class, sequentially move to large fluted disc direction in flywheel the movable rod position of bitch chain steering wheel, and the spring that is fixed on connecting rod this moment also can be along with advancing shelves to larger Flywheel fluted disc, (trample required strength along with diminishing this moment and be tightened up gradually, because the number of teeth gap of deep bid and rear flywheel is fewer).And if during change-speed box start back speed (loosening the speed change cable), this moment, spring was returned to state (not stressed) originally gradually, elastic force by its involution,, along with the class that moves back shelves, make gradually the movable rod position of bitch chain steering wheel come less Flywheel fluted disc (trampling required strength this moment along with becoming large).So, there is human hair to understand the inverse type change-speed box on market, its operating principle is just opposite with the forward formula, namely when change-speed box start (volume draws the speed change cable), along with the shelves that advance of speed change class, sequentially move to less fluted disc direction in flywheel the movable rod position of bitch chain steering wheel, otherwise if loosen the speed change cable, can allow the movable rod position of bitch chain steering wheel sequentially to larger fluted disc direction in flywheel, move by the involution elastic force of connecting rod upper spring, therefore can be more laborsaving in the need climbing.But, no matter the Rear Derailleur that is cantilever linkage spring loaded forward or backwards has a common shortcoming, namely become easily infected by silt in the process of speed change, even press from both sides attached weeds etc., easy to clean not only, and easily cause speed change system malfunctioning, and easily take off chain, cause user's inconvenience, in view of this, the contriver wishes that this revolutionary invention can replace existing Rear Derailleur.
Summary of the invention
The object of the present invention is to provide a kind of sliding rail type rear speed changer, to solve in prior art Rear Derailleur, become easily infected by silt or press from both sides attached weeds and easily cause the problem that whole speed change system is malfunctioning and take off chain.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of sliding rail type rear speed changer wherein, comprises at least: one affects part, a slide track seat, a sliding part; This affects an end of part to be fixed on the vehicle frame permanent seat, and the other end is fixed on slide track seat; Be provided with at least one slide rail in this slide track seat, establish at least one can pulling and the runner that moves in slide rail at slide track seat through the speed change cable on this sliding part, this sliding part other end is linked to the idle pulley folder and can drives the chain on idle pulley and produce displacement on flywheel.
Further, this affects part to be arranged with upper arm and underarm and utilizes screw to be combined with slide track seat and fix.
Further, this slide track seat is provided with for controlling the fin of sliding part at the slide track seat up stroke.
Further, this slide track seat is provided with external slide rail and interior slide rail.
Further, this external slide rail content is provided with spring, this spring can make when making the change-speed box start sliding part on slide track seat along with different location speed changes can back and forth be located.
Further, this external slide rail lower opening is sentenced screw and lower cover is screwed togather and seal external slide rail, and spring is limited in external slide rail.
Further, this slide track seat top is provided with one and has the upper cover of screw, and is fixed in the place, top of slide track seat with screw, and the screw place of this upper cover is provided with one and is used for the fixedly adjustment screw of speed change cable.
Further, this sliding part is provided with external slide rail runner and interior slide rail runner.
Further, this sliding part is provided with for the connecting element in conjunction with interior slide rail runner, and this connecting element is provided with screw, and screws togather interior slide rail runner with screw slide rail runner in this can be slided on the interior slide rail of slide track seat.
Further, this sliding part place is provided with screw, in order to sliding part, with the idle pulley folder, utilizes screw that two assemblies are combined.
After adopting said structure, the present invention is when the Rear Derailleur start, the speed change cable can pull sliding part to make it to move on the slide track seat track, the other end because of sliding part is linked to the idle pulley folder again, thereby make the chain that is engaged on idle pulley, make kinetic energy produce displacement on flywheel along with change-speed box when speed change, therefore can allow chain be engaged in different Flywheel fluted disc positions, the effect of reaching smoothly speed change.The present invention, by the mode of slide track seat is set, reduces thereby play the effect of being infected with silt or pressing from both sides attached weeds.
