Description
Technical field
Electricity-saving one-way overrunning clutch belongs to traffic tool accessory field.Be applied to electric bicycle, electric vehicle transmission deceleration system.
Background technique
At present, mono-directional overrun clutch is made up of inner ring, outer ring, cover plate, planet pin, ratchet and ratchet jump ring, the outer ring external diameter is the same big with two cover plate external diameters, the ratchet jump ring is stuck in the groove of inner ring and two ratchets, the little arc surface of ratchet is close in the circular groove of inner ring, by the speed of related movement variation joint or the disengagement automatically of driving and driven part.
The technological deficiency that exists is, 1. mono-directional overrun clutch outer ring external diameter is the same with the cover plate external diameter big, and weight is big, and after the motor outage, the coast time lacks, and electric bicycle, electric vehicle power consumption are many.2. jump ring elastic force is bigger, and ratchet and outer ring flank of tooth contact force are big, and outer ring when running, the frictional force of ratchet and the outer ring flank of tooth is big, and after the motor outage, the coast time lacks, and electric bicycle, electric vehicle power consumption are many.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problem that existing electric bicycle, electric vehicle mono-directional overrun clutch weight are big, power consumption is many, design a kind of reliable in structure, operate steadily, in light weight, ratchet and the little electricity-saving one-way overrunning clutch of outer ring inner toothed surface frictional force.
The technical solution adopted for the present invention to solve the technical problems is: this electricity-saving one-way overrunning clutch, comprise: the outer ring, inner ring, ratchet, cover plate and planet pin, inner ring is in ratchet is installed in the outer ring, cover plate is installed in outer ring and inner ring two ends, it is characterized in that: cover plate is a pair of, adopt middle circular subsumption architecture to upper process, being provided with three on the cylindrical of projection circular shape makes progress to the broadband of outer process, projection circular shape upwards links to each other also at grade to the outer process broadband with three, a pair of cover plate is with the outer ring, inner ring and ratchet are enclosed in the projection circular shape, and the inner side surface of a cover plate projection circular shape is provided with one 45 degree draw-in groove therein, the outer chamfering place of corresponding with it is outer ring is provided with one 45 degree draw-in groove, two draw-in grooves cooperate, and planet pin is installed in a pair of cover plate upwards on the broadband of outer process.
Ratchet be the semicylinder formula and be installed in the outer ring and inner ring between, pressure spring is installed on the inner ring, withstands the semicylinder ratchet by steel ball, the engagement of semicylinder ratchet and outer ring internal tooth.
Compared with prior art, the beneficial effect that electricity-saving one-way overrunning clutch of the present invention had is: because a pair of cover plate adopts punching type, in light weight, reliable in structure, operate steadily, economize on electricity.Planet pin is installed on a pair of cover plate projection broadband, and planet pin is no longer installed in the outer ring, and the metal solid diameter significantly reduces, clutch weight saving 2/5ths; The pressure spring that adopts is littler than jump ring volume, elastic force is little, good reliability, withstands the semicylinder ratchet and the outer ring internal tooth meshes more flexibility and reliability by steel ball, reduces friction, the coast time is long, after the motor outage, than long one times of original coasting time, little power consumption.

Wherein: 1 outer ring, 2 ratchets, 3 inner rings, 4 a pair of cover plates, 5 steel balls, 6 pressure springs, 7 planet pins, 8 solder joints, 945 degree draw-in grooves.
Embodiment
Below in conjunction with accompanying drawing 1-4 electricity-saving one-way overrunning clutch of the present invention is described further:
Electricity-saving one-way overrunning clutch is made up of outer ring 1, ratchet 2, inner ring 3, a pair of cover plate 4, steel ball 5, pressure spring 6, planet pin 7, solder joint 8,45 degree draw-in grooves 9.Inner ring 3, ratchet 2 are installed in the outer ring 1, ratchet 2 is installed between inner ring 3 and the outer ring 1, a pair of cover plate 4 adopts middle circular subsumption architecture to upper process, and in the projection broadband that three of local projections adorning planet pin 7 make progress outside, adopt arc transition to be connected between the projection broadband that makes progress outside of the circle of a pair of cover plate 4 projections and dress planet pin 7 place's projections, projection also adopts arc transition to be connected with interplanar, the circle of projection upwards links to each other and at grade, a pair of cover plate 4 is enclosed in outer ring 1 in the circle to the outer process broadband with three.A pair of like this cover plate 4 not protruding part direct spot welding has replaced the periphery of original structure outer ring together, thereby has alleviated the weight of electricity-saving one-way overrunning clutch, clutch weight saving 2/5ths.In addition, outstanding circular inner side surface is provided with one 45 degree draw-in groove 9 on cover plate 4 therein, and also there is one 45 degree draw-in groove at the outer chamfering place of corresponding with it is outer ring 1, and two draw-in grooves cooperate, add outer ring 1 and a pair of cover plate 4 interference fit, guarantee that a pair of cover plate 4 does not relatively rotate with outer ring 1.Assemble a pair of cover plate 4 in back and adopt spot welding to connect, improve connection reliability.Adopt a pair of cover plate 4 of this structure can effectively alleviate the weight of clutch, save steel, be fit to lightweight requirements, can guarantee performance of clutch and rigidity again.After the motor outage, the coast time is long, little power consumption.
Ratchet 2 is designed to the semicylinder formula, the jump ring that original elastic force is bigger is designed to the less pressure spring of elastic force 6, adopt less pressure spring 6 of elastic force and steel ball 5 to cooperate, make semicylinder ratchet 2 and outer ring 1 internal tooth engaging force contact little, frictional force is little when slide in outer ring 1, effectively prolongs the coast time, after the motor outage, long one times of the original coasting time of coast time ratio, little power consumption.
Working procedure:
Electricity-saving one-way overrunning clutch is applied in the transmission deceleration system of electric bicycle, electric vehicle.Behind the electrical power, rotor drives main shaft and rotates, and is fixed on the pinion rotation on the main shaft, and small gear drives the planetary pinion that is contained on the electricity-saving one-way overrunning clutch and rotates, and the ring gear that planet gear drives is set on the wheel rotates, thereby turns a wheel.Motor drives wheel after by double reduction like this.After the motor outage, wheel moves on owing to inertia.Wheel rotates by the planet gear drives clutch.
