Abstract
The utility model relates to a power saving bicycle tyre, which comprises a tyre tooth, a tyre waist, a tyre roof and a tyre crown. The middle of the tyre roof is provided with a circle of flat-shaped tyre crown protrusion which is 2 to 8 mm in height and 10 to 20 mm in width. The utility model is mainly designed into a bicycle tyre with coarse specification, and is used for dirt bicycles, speed changing and common bicycles, and also is used for low-speed motorcycles. So the utility model has the advantages of the existing coarse and fine tyres and overcomes the disadvantages of the existing coarse and fine tyres, so the bicycles with coarse tyres can be ridden on the flat roads with obvious labor saving.
Description
The present invention relates to vehicle tyre, particularly about a kind of novel labour saving cycle casing.
At present, cycle casing can divide carse, medium and small three kinds by the diameter specification, the cover tire of standard bicycle belongs to medium specification, more and more in recent years mountain bikes that occur, then cover tires that adopt thick specification such as speed change woman women's bicycle have the small part light roadster then to adopt thin specification cover tire more.Thin cover tire, on smooth, strong road, because of little with the road surface contact surface, friction drag is little, seems very light, but if thin cover tire is bad in road conditions, or when riding on the muddy dirt road, then easily sagging, even can not ride.Thick cover tire is mainly used in mountain bike, and in rugged hill path, or muddy dirt road is when riding, because of big with ground contact surface, pressure is little, so be difficult for sinking, can normally ride, but on smooth road, but because of tire is thick, resistance is big, require great effort when riding.Then still there are some shortcomings of thickness cover tire in the cover tire of standard bicycle medium-coarse.
Purpose of the present invention, provide a kind of novel labour saving cycle casing, it mainly is suitable for mountain bike, also be suitable for ordinary bicycle or low speed motor bike, this novel cover tire is ridden on the road of road conditions difference, has the advantage of existing thick cover tire, on the good road of road conditions, ride, then have the little labour-saving of thin tire resistance advantage.
The utility model content is: the novel labour saving cycle casing, comprise tire tooth (1), tire waist (2), tire top (3) and crown (4), at middle part, tire top the flat-shaped crown projection of one circle is arranged, its no decorative pattern in surface, vertical or the transverse concave groove decorative pattern of one circle is perhaps arranged, two road steel wires also can be set at the crown root.
Below in conjunction with drawings and Examples, describe concrete technical scheme of the present utility model in detail.
Fig. 1 is existing cover tire schematic cross section.
Fig. 2 is novel cover tire schematic cross section.
Wherein (1) is the tire tooth, and (2) are the tire waist, and (3) are the tire top, and (4) are crown, and (5) are steel wire.
Fig. 3, Fig. 4 are respectively the local outside face scheme drawing of novel cover tire.
Among Fig. 3, crown has vertical sipe (6).
Among Fig. 4, crown has transverse concave groove decorative pattern (7).
Existing cycle casing, surface have of all kinds for increasing the decorative pattern of friction force, slide but whole cover tire surface is the garden.The utility model then at the middle part, tire top of existing cover tire, is provided with the flat-shaped crown projection of a circle, and its height is 2-8mm, and wide is 10-20mm.Convex surfaces does not have decorative pattern, and circle vertical sipe, perhaps a transverse concave groove decorative pattern can also be arranged.The root of crown projection does not have steel wire, and 1-2 root steel wire can also be set.Present embodiment at middle part, tire top, has the flat-shaped crown projection of a circle, and its height is 5mm, and wide is 15mm, and there is vertical sipe on the surface, at its root 2 steel wires is set, to gain in strength.The utility model also can adopt the utility model scheme to be designed to thick specification cover tire on middle specification cover tire and low speed motor casing.Adopt this later-model mountain bike, hill path in the road conditions difference, when riding on the muddy dirt road, under the normal rounds air pressure, it is the crown of projection and the part tire top of crown both sides with ground-surface the contact, and is basic identical with existing thick cover tire situation, big with the ground contact surface, pressure is little, is difficult for sinking, and can ride as usual.When on the good road of road conditions, riding, with ground-surface contact surface be narrower crown, this is basic identical with existing thin cover tire situation, has reduced to contact and friction drag with ground-surface, make ride laborsaving.
The utility model mainly is suitable for the thick tire cycle casing such as mountain region, speed change, women women's bicycle, also can make the low speed motor casing, the novel cover tire of specification in also can being designed to, be used for ordinary bicycle, make it to overcome the shortcoming that existing thick, thin cover tire exists, and have the advantage of thick, thin cover tire concurrently. Existing thick tire bicycle is ridden at road can be obviously laborsaving.
Claims (2)
1, novel labour saving cycle casing comprises tire tooth (1), tire waist (2), tire top (3) and crown (4), and it is characterized in that: there is the flat-shaped crown projection of a circle at middle part, tire top, perhaps in the root tire top of flat-shaped crown projection 1-2 root steel wire (5) is set.
2, novel labour saving cycle casing according to claim 1 is characterized in that: the high 2-8mm of flat-shaped crown projection, and wide 10-20mm, convex surfaces does not have decorative pattern, and a circle vertical sipe (6) is perhaps arranged, and a circle transverse concave groove decorative pattern (7) is perhaps arranged.
