In the existing speed regulator, for example, the invention patent with the publication number of CN 105438397B discloses a bicycle speed changing device, which is provided with an upshift push rod and a downshift push rod, wherein the upshift push rod is used for pushing a speed regulating ratchet to rotate, meanwhile, the speed regulating ratchet drives a guide rope to pull a derailleur, after the upshift push rod is loosened, the speed regulating ratchet is limited by a limiting pawl, and the speed regulating ratchet is prevented from rotating under the action of a torsion spring, so that the speed regulating ratchet can be ensured to stay at the position after shifting; the gear-reducing push rod is used for releasing the limiting pawl to enable the limiting pawl to be far away from the current ratchet groove of the speed regulating ratchet wheel, and due to the lack of limiting, the speed regulating ratchet wheel can rotate under the acting force of the torsion spring to reduce gears.
Furthermore, when the gear-up push rod is loosened after gear-up, the reset spring of the gear-up push rod drives the gear-up push rod to rotate for resetting, so that the drive pawl on the gear-up push rod moves to the original position; in order to prevent the driving pawl from limiting the speed regulating ratchet wheel in the gear reducing process, the conventional speed regulator is provided with a lifting boss at the reset original position of the driving pawl, so that the driving pawl which moves to the original position in a reset manner is lifted and suspended outside the next outer ratchet groove, the limitation of the driving pawl on the speed regulating ratchet wheel can be avoided, the speed regulating ratchet wheel can be released after the limitation of the limiting pawl is relieved, and the gear reducing operation is completed. Although the structure can solve the problem of limiting the speed regulating ratchet wheel by the driving pawl, the following problems also exist at the same time:
in the following upshifts, the rider pushes the upshifting push rod, which needs to complete two necessary strokes: the first section of stroke is to drive the driving pawl from the lifting boss to the current outer ratchet groove, and the second section of stroke is to drive the driving pawl to drive the speed regulating ratchet wheel to rotate forwards; therefore, in actual use, the rider can firstly pass through the stroke of one section of the virtual position and then enter the stroke of the gear-up, so that the rider can possibly feel the illusion of gear-up, the gear-up operation is difficult to clearly and accurately control, the total stroke is long, a large driving amplitude is needed, the convenience is poor, and the experience effect is to be improved.
