Abstract
The utility model relates to an energy-saving double-slot belt wheel for crank shafts of mini cars, which is composed of a pair of single slot belt wheels which are combined into a whole, the middle part is provided with holes and a key slot, and the periphery is provided with a belt slot. The diameters of the two single slot belt wheels are not equal, and the utility model is the double-slot step belt wheel. The utility model is especially suitable for being arranged on the crank shafts of the engines of the mini cars to drive generators and air conditioners. The utility model has the advantages of light weight, reasonable reduction of the rotary speed of the air conditioners, little influence to the start and the running speed of the mini cars, fuel and money saving, pollution reduction, etc., and the utility model is a novel energy-saving double-slot belt wheel.
Description
The utility model relates to a kind of driving component, is suitable for doing the double flute vee-pulley of minicar engine bent axle especially.
At present, the double flute belt wheel on the automobile engine crankshaft is as the generator and the air conditioner of driving wheel difference driving automobile, the equal diameters of two wheels of this belt wheel.This transmission all is suitable in the bigger general car of horsepower, minibus, truck, motorbus.Yet, as " Xiali " board car etc., tend to produce generator and air conditioner drive simultaneously at the little minicar of horsepower, what be at a stop can not start, and the speed of travelling is influenced, can only air conditioner starts up the car or raising speed by turning off, both are difficult to take into account, and it is worried that driver and passenger feel deeply.
In view of the above-mentioned deficiency of prior art, the utility model provides a kind of follow-on double flute belt wheel, and is less to starting with the influence of travelling speed when driving generator and air conditioner simultaneously, and can reduce the energy-conservation double flute belt wheel of minicar engine bent axle of fuel consumption.
The utility model can be realized with following measure: it is formed by the unification of a pair of single troughed belt wheel, there are axis hole and keyway in the center, and periphery has trough of belt, yet, the diameter of two single troughed belt wheels in the double flute belt wheel that it is integrated is unequal, promptly makes a kind of double flute ladder belt wheel.
Should, the diameter of single troughed belt wheel of drive generator is greater than the diameter of the single troughed belt wheel that drives air conditioner, and both diameter ratios are 14 to 11～9.
Fig. 1 is the utility model structural representation.
Fig. 2 is the right elevation of Fig. 1.
The utility model is described in detail below in conjunction with embodiment: whole available cast steel casting realize, drives the diameter 140 (mm of unit, down with) of single troughed belt wheel 2 (to call bull wheel in the following text) of generator, takes turns thickly 15, and trough of belt 3 is dark 9, and the top of trough of belt 3 is wide by 10, and the bottom is wide by 5; The diameter that drives single troughed belt wheel 4 (calling steamboat in the following text) of air conditioner is 110, take turns thick 15, wide by 10 on the trough of belt, following wide by 5, groove depth 9.The diameter 25 of axis hole 1, hole depth 30, the length of keyway 5 are 30, and be dark 4, wide by 5.
Do not have the branch of size in the prior art because of two-wheeled, diameter is 140, and the diameter of the driven pulley of air conditioner is 87, so its rotating ratio is 87/140, and the diameter of steamboat 4 is 110 after improving, and rotating ratio becomes 87/110, the rotating speed of air conditioner is slack-off, and the load that motor drives alleviates relatively.Here, for the generated energy that makes generator is unlikely to reduce, do not change the rotating ratio of bull wheel 2 and generator follower, for a change rotating ratio reaches the enlarged diameter of the follower on the air conditioner at purpose, because of the diameter of such words driving wheel and follower all big, the weight of wheel itself increases, and still will increase the load of motor.
The diameter proportion of bull wheel 2 and steamboat 4 should be suitable, and ratio is too small, and as 14: 13 or 14: 12, load reduced not obvious, is difficult to realize that fuel-economizing is not remarkable yet to starting and the little purpose of scanning frequency influence.If ratio is excessive, as 14: 4 or 14: 3, then the air conditioner rotating speed was slow excessively, though fuel-economizing is remarkable, air conditioner does not almost have the air-conditioning effect, thus consider appropriateness, better with 14: 11.Under this ratio, the 500 kilometers pacts of whenever travelling can be economized 3 kilograms in gasoline, economize gasoline and take more than 6 yuan.In the whole nation, fuel-economizing, to save money, subtract dirty meaning non-shallow.
The utility model has compared to existing technology light weight, rationally lowers the air-conditioner rotating speed, to little The impact of the starting of type car and scanning frequency is little, fuel-economizing, saves money, subtracts the advantages such as dirty effect is remarkable.
Claims (2)
1. energy-conservation double flute belt wheel of minicar engine bent axle, form by the unification of a pair of single troughed belt wheel, there are axis hole (1) and keyway (5) in the center, periphery has trough of belt (3), the diameter of two single troughed belt wheels in the double flute belt wheel that it is characterized in that being integrated is unequal, promptly becomes a kind of double flute ladder belt wheel.
2. double flute belt wheel as claimed in claim 1 is characterized in that driving the diameter of single troughed belt wheel (2) diameter of generator greater than the single troughed belt wheel (4) that drives air conditioner, and both diameter ratios are 14 to 11～9.
