Abstract
The utility model provides a men power tricycle with a speed variator, which is composed of a tricycle and a gear box arranged on the tricycle, wherein, a left and a right foot pedals are respectively connected with a dynamic force gear shaft of the gear box, a driving shaft on the gear box is connected with a toothed disc mill through a connecting rod, the toothed disc mill is matched with a gear, and the gear and a bearing are respectively arranged on a rear wheel shaft of the tricycle. The utility model solves the problem that the existing tricycle can not change speed and can not run too long due to easily broken chains, and is a widely popularized technology.
Description
The utility model relates to a kind of manual tricycle that has variable transmission mechanism.
At present, the normally used manual tricycle of people mostly is to come its trailing wheel of transmission to rotate with foot-operated toothed disc by chain.There is following shortcoming in the manual tricycle of this kind form in the middle of reality is used: one, can't speed change, and when going up a slope, heavy duty quite requires great effort; Two, chain often ruptures easily and can't travel.Thus, brought inconvenience to the user.
The purpose of this utility model is for solving above-mentioned insufficient section, a kind of manual tricycle that has variable transmission mechanism is provided, it can be when heavy duty be gone up a slope the speed governing of conversion gear make and scrunch very laborsavingly, and thoroughly avoided taking place because of the situation that the chain fracture can't be travelled.
The purpose of this utility model is achieved through the following technical solutions: the manual tricycle that has variable transmission mechanism, it has three-wheel vehicle, three-wheel vehicle is provided with change speed gear box, left and right foot-operated respectively with change speed gear box on the power gear axle join, transmission shaft on the change speed gear box joins by connecting rod and toothed disc respectively, toothed disc matches with gear, and gear, bearing are installed in respectively on the hind axle of three-wheel vehicle.
Can also take following technical scheme for further realizing the purpose of this utility model: the manual tricycle that has variable transmission mechanism, transmission shaft is a tubulose, be respectively arranged with 180 ° upright arm each other on it, join with an end of connecting rod respectively on the upright arm, the other end of connecting rod joins with toothed disc respectively.Change speed gear box is provided with the strut bar that joins with bearing, and the toothed disc bearing is installed in strut bar respectively.The afterbody of connecting rod is respectively crooked shape, and joins with cross one another form and toothed disc, and its curve contacts with bearing.
Advantage of the present utility model: one, reasonable in design, it adopts change speed gear box transmission hind axle, the user is arbitrarily conversion gear speed governing when heavy duty is gone up a slope, make scrunch very laborsaving, moreover, it has substituted chain gear with the connecting rod transmission, so thoroughly avoided taking place because of the situation that the chain fracture can't be travelled; Two, it is provided with bearing on strut bar, the curve that makes two connecting rods respectively with this bearing as fulcrum, make two connecting rods more laborsaving when the handsetting gear dish; Three, simple in structure, easy making, with low cost, easy to use and reliable.Widespread use of the present utility model can produce good social, economic benefit.
Figure of description is the structural representation that the utility model removes left side trailing wheel and back vehicle frame, mainly illustrates from change speed gear box 4 to hind axle the structure division 9.
In conjunction with the embodiments the utility model is described in further detail with reference to the accompanying drawings.
The manual tricycle that has variable transmission mechanism of the present utility model, it has three-wheel vehicle 1, three-wheel vehicle 1 is provided with change speed gear box 4, left and right foot-operated 3,17 respectively with change speed gear box 4 on power gear axle 2 join, transmission shaft 5 on the change speed gear box 4 joins by connecting rod 7,14 and toothed disc 12 respectively, toothed disc 12 matches with gear 10, and gear 10, bearing 11 are installed in respectively on the hind axle 9 of three-wheel vehicle 1.Transmission shaft 5 is a tubulose, is respectively arranged with 180 ° upright arm 6,15 each other on it, joins with an end of connecting rod 7,14 respectively on the upright arm 6,15, and the other end of connecting rod 7,14 joins with toothed disc 12 respectively.Change speed gear box 4 is provided with the strut bar 8 that joins with bearing 11, and toothed disc 12, bearing 13 are installed in strut bar 8 respectively.The afterbody of connecting rod 7,14 is respectively crooked shape, and joins with cross one another form and toothed disc 12, and its curve contacts with bearing 13.
During making, process various parts assemblings by above-mentioned requirements and get final product.During use,, arbitrarily operate shifter bar 16 and make three-wheel vehicle 1 be in the speed change motoring condition to get final product according to actual conditions vehicle-mounted and that go up a slope.The structure of the inner structure of change speed gear box 4 of the present utility model and three-wheel vehicle 1 is prior art, does not just give unnecessary details one by one here.
