Description
The utility model relates to motorcycle transmission of power clutch field, especially a kind of fuel-economizing tackle gear that is applicable to motorcycle, and it designs according to the free wheel device principle.
Have the people of research all to know slightly to motorcycle, but the variable block motorcycle is more fuel-efficient, and stepless speed-change motorcycle oil consumption comparatively, its main cause is that the former is equipped with the gear speed changer, the latter does not then have.The transmission principle of general stepless speed-change motorcycle is: because of the engine-driving mainshaft gear rotates, drive the pinion axle and rotate, the small gear on the pinion axle is meshed with gear on being fixed on rear-wheel spindle, finally drives the trailing wheel rotation, and motorcycle is moved forward.Because whole power-transmission system combines all the time, no matter be at descending stream car or when idling is travelled, because of the resistance of each transmitting movement parts, do not realize sliding, also increased the wearing and tearing between each parts; Can moreover along with constantly raising up of gas price, the fuel-economizing problem also more and more be subject to people's attention, therefore, change relevant modular construction and make it to help the research topic that fuel-economizing has become the relevant personnel on stepless speed-change motorcycle.
A kind of design science that the purpose of this utility model is developed at existing deficiency in the above-mentioned prior art just, rational in infrastructure, fuel-economizing tackle gear that oil-saving effect significantly is applicable to motorcycle, this tackle gear is according to the free wheel device principle design, can running at high speed or make during descending rear-wheel spindle and driving mechanism throw off, utilize the coast of car, and then reaches the fuel-economizing purpose.
The purpose of this utility model can realize by following scheme: the fuel-economizing tackle gear that originally is applicable to motorcycle comprises the interior slipping ring that is combined on the motorcycle rear axle and forms with the external toothing on the slipping ring outer ring in the mode suit movingly, external toothing is meshed with power transmitting gear, being processed with a plurality of cross sections that are evenly distributed on the excircle of interior slipping ring is the groove of wedge shape, the direction of wedge-shaped impression and the sense of rotation of external toothing adapt, spring and rolling clutch piece all are installed in each groove, spring one end roof pressure is on the rolling clutch piece, the other end is fixed in the wide end of wedge-shaped impression, is provided with annular cover plate in the groove both sides of placing the rolling clutch piece.
In the utility model, the groove that to be processed with five cross sections that are evenly distributed on the excircle of interior slipping ring be wedge shape, the bottom surface of groove can be a cambered surface, also can be a plane; Be installed in rolling clutch piece in the groove and can be cylinder and roll, also can be spherical shape.
The ring platform all is processed with the outer shroud platform in the excircle both sides of interior slipping ring in the inner circumference both sides of external toothing all are processed with, and annular cover plate is installed in the annular groove of being made up of the above two inner and outer rings platforms.
Working principle of the present utility model is: when the motor proper functioning, give the final stage gear by transmission system with transmission of power, the rolling clutch piece is under the effect of spring, tightly roof pressure is on the inner peripheral surface of external toothing and the groove floor on the interior slipping ring (the rolling clutch piece is in narrow end), make both become a rigid construction and rotation synchronously, therefore, rear-wheel spindle rotates with the rotation of motor, along with the rotating speed of motor increases progressively, the speed that car travels is also more and more higher.When motor slows down suddenly or is flame-out, external toothing will or stop operating gradually with the main axis transmission system decelerate, at this moment, the rear-wheel spindle rotating speed is greater than external toothing, the rolling clutch piece that is positioned between the two will move to the wide end of wedge-shaped impression by against the force of the spring under the acting in conjunction of slipping ring and external toothing, slipping ring and external toothing are thrown off in making, and slipping ring was rotated further in rear-wheel spindle drove under effect of inertia, thereby reached the fuel-economizing purpose.When motor quickens once more, make the external toothing rotating speed be higher than interior slipping ring, the rolling clutch piece under the active force of spring again roof pressure on the groove floor of the inner peripheral surface of external toothing and interior slipping ring, both are rotated once more synchronously.
The utility model compared with prior art has the following advantages:
1, after adding this tackle gear on the motorcycle, can obviously play the fuel-economizing effect, after tested, hundred kilometers fuel-economizings 15～30%, idling slides and can reach 150 meters～300 meters, having changed pedal-type (general stepless change is pedal-type) does not have the oiling present situation of modulability, has alleviated driver's economic burden.
2, make that the internal organ accessory of motor is not easy to wear, prolong the working life of motor.
3, owing to reduced fuel consumption, therefore also reduced the pollution of motorcycle to environment.
Certainly, also there is the phenomenon of blemish in an otherwise perfect thing in the utility model, and promptly in the process of sport car, owing to banish at a high speed, after speed reduced, oiling can occur that car impacts forward or little shaking again, and this phenomenon is that the fuel-economizing tackle gear is fully in conjunction with the process that must have.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the topology view that the power-transmission system of the cunning skiving wheel of this section is housed.
Fig. 2 is the A-B-C sectional view of Fig. 1.
The utility model is done below in conjunction with accompanying drawing and is described in further detail:
