Abstract
The invention provides a jaw-type overrunning clutch of an energy-saving racing bicycle. The jaw-type overrunning clutch comprises a spindle, a left shaft-end bearing block, a power ratchet, a hub ratchet, a hub, a chain wheel flange, a right shaft-end bearing block, a left shaft-end nut, a left shaft-end bearing, a ratchet check ring, a left hub bearing, a right hub bearing, a flange nut, a right shaft-end bearing and a right shaft-end nut. The jaw-type overrunning clutch is used for transferring torque, large torque can be transferred, and teeth of the ratchets have high strength and can bear a certain impact, so the jaw-type overrunning clutch is stable and reliable; since the ratchets are connected with the spindle through spiral spline grooves, engagement and disengagement of the clutch are completed automatically, the operability is high, the engaging process is reliable, and the ratchets are completely locked; the clutch is quick in disengaging process, and the power ratchet is disengaged from the hub ratchet completely after separation, so no additional clutch resistance will be generated, and the energy-saving racing bicycle can save more energy.
Description
Technical field
The invention belongs to energy-conservation racing car field, particularly relate to the castellated free wheel device of a kind of energy-conservation racing car.
Background technique
Energy-conserving and environment-protective have become one of the theme in the world at present, for the theory energy saving vehicle sports contest of energy-saving and emission-reduction, also arise at the historic moment.Race is mainly the theme with energy-conserving and environment-protective, and the design of clutch is one of them very crucial factor.
In energy-conservation racing car, clutch Main Function is the transmission of power of separated and closed engine and driving wheel, mainly contains the solution that adopts two kinds for the current energy-conservation racing car of the design of clutch.To adopt a flywheel structure, flywheel structure more being applied in bicycle at present, its maximum feature is continuity and the ease for operation of power transmission, does not need other winding machine power separated and closed.But its carrying Maximum Torque is limited, and transmission efficiency is low, poor stability.Another kind is to adopt jaw clutch structure, and the bearing capacity of jaw clutch is stronger, but its separated and closed moment can produce larger impact, and separated and closedly need to special-purpose mechanism control realization, relative complex.These two kinds of solutions all cannot be given full play to the performance of clutch due to the defect of self.
Summary of the invention
The technical problem solving
In order to solve efficiency, load and the operational issue of energy-conservation racing car clutch designs simultaneously, the invention provides a kind of castellated free wheel device, the separation of this clutch and the closed participation that automatically completes minimizing people by structure, and the moment of torsion transmitting is large, efficiency is high, thereby makes energy-conservation racing car energy-conserving and environment-protective more.
Technological scheme
The castellated free wheel device of described a kind of energy-conservation racing car, it is characterized in that: comprise main shaft, left axle end bearing seat, power ratchet, flower-drum ratchet, flower-drum, sprocket wheel flange, right axle end bearing seat, also comprise left shaft end nut, left axle end bearing, ratchet back-up ring, left flower-drum bearing, right flower-drum bearing, flange nut, right axle end bearing, right shaft end nut;
The left bearing fitting surface close-fitting of the outer ring of left flower-drum bearing and flower-drum, the inner ring of left flower-drum bearing and main shaft cunning are joined; The right bearing fitting surface close-fitting of the outer ring of right flower-drum bearing and flower-drum, the inner ring of right flower-drum bearing and main shaft cunning are joined; Flower-drum ratchet is connected by bolt and flower-drum; Sprocket wheel flange is connected with main shaft by spline, and fastening by flange nut and main shaft; Power ratchet coordinates with main shaft by helical spline, and ratchet back-up ring is connected by circlip groove with main shaft; The outer ring of left axle end bearing and left axle end bearing seat close-fitting, its inner ring and main shaft cunning are joined, and fastening by left shaft end nut and main shaft; The outer ring of right axle end bearing and right axle end bearing seat close-fitting, its inner ring and main shaft cunning are joined, and fastening by right shaft end nut and main shaft; Left axle end bearing seat and right axle end bearing seat and energy-conservation racing car vehicle frame are fixed.
Beneficial effect
The invention has the beneficial effects as follows: 1. by jaw clutch transmitting torque, can transmit larger moment of torsion, ratchet tooth intensity is higher can bear certain impact, reliable and stable.2. ratchet is connected with main shaft by Turbo Flora keyway, and clutch is closed to be completed automatically with separated, strong operability, and closing course is reliably completely locked.3. clutch disengage process is rapid, separated rear completely separated, can not produce additional clutch drag, and energy-conservation racing car is more energy-conservation.

Embodiment
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
A kind of energy-conservation racing car free wheel device design of the present invention, comprises main shaft 1, left shaft end nut 2, left axle end bearing seat 3, ratchet back-up ring 4, power ratchet 5, flower-drum ratchet 6, flower-drum 7, sprocket wheel flange 8, flange nut 9, right axle end bearing seat 10, right shaft end nut 11, left axle end bearing 12, left flower-drum bearing 13, right flower-drum bearing 14, right axle end bearing 15.
Left flower-drum bearing 13 outer rings and flower-drum 7 left bearing fitting surface close-fittings, left flower-drum bearing 13 inner rings and main shaft 1 are slided and are joined; Right flower-drum bearing 14 and flower-drum 7 right bearing fitting surface close-fittings, right flower-drum bearing 14 inner rings and main shaft 1 are slided and are joined.Flower-drum ratchet 5 is connected by bolt and flower-drum 7.Sprocket wheel flange 8 is connected with main shaft 1 by spline, by flange nut 9 and main shaft 1, is connected.Power ratchet 5 coordinates with main shaft 1 by helical spline, and ratchet back-up ring 4 is connected by circlip groove with main shaft 1.Left axle end bearing 12 outer rings and left axle end bearing seat 3 close-fittings, inner ring and main shaft 1 are slided and are joined, and by left shaft end nut 2, are connected with main shaft 1; Right axle end bearing 15 outer rings and right axle end bearing seat 10 close-fittings, inner ring and main shaft 1 are slided and are joined, and by right shaft end nut 11, are connected with main shaft 1.Left axle end bearing seat 3 is fixed with energy-conservation racing car vehicle frame with right axle end bearing seat 10.
The automatic closing course of clutch: energy-conservation racing car power is delivered to sprocket wheel flange 8 by chain transmission, sprocket wheel flange 8 drives main shaft 1 rotation by spline.Main shaft 1 rotation, power ratchet 5 speed are lower than main shaft 1, under the leading role of main shaft helical spline gradually near flower-drum ratchet 6 until the sour jujube tooth of power ratchet 5 embed completely in flower-drum ratchet 6.Under the resisting moment effect of flower-drum, power ratchet 5 is completely locked with flower-drum ratchet 6, flower-drum 7 and sprocket wheel flange 8 synchronous rotaries, and clutch completes automatic closing course.
The automatic separation process of clutch: flower-drum 7 speed are during higher than main shaft 1, power ratchet 5 speed fall behind flower-drum ratchet 6, under the effect of sour jujube tooth, produce axial active force, power ratchet is moved away from flower-drum ratchet along main shaft 1 Turbo Flora keyway, until move to ratchet back-up ring position under the effect of ratchet back-up ring, stop away from, complete automatic separation process.Now flower-drum 7, around main shaft idle running without any additional resisting moment, makes energy-conservation racing car more energy-conservation.
