Description
Technical field
The utility model belongs to energy-conservation racing car field, particularly relates to a kind of castellated free wheel device.
Background technique
Energy-conserving and environment-protective one of theme becoming the world at present, the theory energy saving vehicle sports contest for energy-saving and emission-reduction is also arisen 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 separated and the transmission of power of closed engine and driving wheel, and the current energy-conservation racing car of the design for clutch mainly contains the solution of employing two kinds.One adopts flywheel structure, and flywheel structure is more to be at present applied in bicycle, and its maximum feature is continuity and the ease for operation of power transmission, do not need other mechanism to realize the separation of power and closed.But its carrying Maximum Torque is limited, and transmission efficiency is low, poor stability.Another kind adopts jaw clutch structure, and the bearing capacity of jaw clutch is comparatively strong, but it is separated and closed moment can produce larger impact, and be separated and closedly need special mechanism to carry out control realization, relative complex.These two kinds of solutions all cannot give full play to the performance of clutch due to the defect of self.
Summary of the invention
The technical problem solved:
In order to solve the efficiency of energy-conservation racing car clutch designs, load and operational issue simultaneously, the utility model provides a kind of castellated free wheel device, the separation of this clutch and the closed participation automatically being completed minimizing people by structure, and the moment of torsion transmitted is large, efficiency is high, thus makes energy-conservation racing car energy-conserving and environment-protective more.
Technological scheme:
The castellated free wheel device of described one, it is characterized in that: comprise main shaft, left axle end bearing seat, power ratchet, hub 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 outer ring of left flower-drum bearing and the left bearing fitting surface close-fitting of flower-drum, the inner ring of left flower-drum bearing and main shaft are slided and are joined; The outer ring of right flower-drum bearing and the right bearing fitting surface close-fitting of flower-drum, the inner ring of right flower-drum bearing and main shaft are slided and are joined; Hub ratchet is connected by bolt and flower-drum; Sprocket wheel flange is connected with main shaft by spline, and by flange nut and main shaft fastening; Power ratchet is coordinated 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 are sliding joins, and by left shaft end nut and main shaft fastening; The outer ring of right axle end bearing and right axle end bearing seat close-fitting, its inner ring and main shaft are sliding joins, and by right shaft end nut and main shaft fastening; Left axle end bearing seat and right axle end bearing seat and outside vehicle frame are fixed.
Beneficial effect:
The beneficial effects of the utility model are: 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 being separated, strong operability, and closing course is reliable completely locked.3. clutch disengage process is rapid, and be separated completely after separation, can not produce additional clutch drag, energy-conservation racing car is more energy-conservation.

Embodiment
Now in conjunction with the embodiments, accompanying drawing is further described the utility model:
A kind of energy-conservation racing car free wheel device design of the utility model, comprises main shaft 1, left shaft end nut 2, left axle end bearing seat 3, ratchet back-up ring 4, power ratchet 5, hub 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 ring and flower-drum 7 left bearing fitting surface close-fitting, left flower-drum bearing 13 inner ring and main shaft 1 are slided and are joined; Right flower-drum bearing 14 and flower-drum 7 right bearing fitting surface close-fitting, right flower-drum bearing 14 inner ring and main shaft 1 are slided and are joined.Hub ratchet 5 is connected by bolt and flower-drum 7.Sprocket wheel flange 8 is connected with main shaft 1 by spline, is connected by flange nut 9 and main shaft 1.Power ratchet 5 is coordinated 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 ring and left axle end bearing seat 3 close-fitting, inner ring and main shaft 1 are slided and are joined, and are connected with main shaft 1 by left shaft end nut 2; Right axle end bearing 15 outer ring and right axle end bearing seat 10 close-fitting, inner ring and main shaft 1 are slided and are joined, and are connected with main shaft 1 by right shaft end nut 11.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 conveyer, sprocket wheel flange 8 drives main shaft 1 to rotate by spline.Main shaft 1 rotates, power ratchet 5 speed lower than main shaft 1, under the leading role of main shaft helical spline gradually near hub ratchet 6 until the sour jujube tooth of power ratchet 5 embeds in hub ratchet 6 completely.Under the resisting moment effect of flower-drum, power ratchet 5 is completely locked with hub ratchet 6, and flower-drum 7 and sprocket wheel flange 8 synchronous rotary, clutch completes automatic closing course.
The automatic separation process of clutch: when flower-drum 7 speed is higher than main shaft 1, power ratchet 5 speed falls behind hub ratchet 6, axial active force is produced under the effect of sour jujube tooth, power ratchet is made to move away from hub ratchet along main shaft 1 Turbo Flora keyway, until move to ratchet back-up ring position stop under the effect of ratchet back-up ring away from, complete automatic separation process.Now flower-drum 7 is around main shaft idle running without any additional resisting moment, makes energy-conservation racing car more energy-conservation.
