Abstract

The utility model discloses a pedal tricycle for two persons, comprising two handle bars that can control a front fork, two tricycle seats, two sets of pedals, a wheel disc, a chain belt and a flywheel drive system; a rear shaft is composed of two equal length half shafts that are plugged together; the pedal tricycle is driven by the double rear wheels; the riding is force saving and safe.

Description

The double pedal three-wheel vehicle

The utility model belongs to the vehicle, relates to a kind of double pedal three-wheel vehicle.

Three-wheel vehicle commonly used now is single foot-operated, drives by one group of pedal, wheel disc, chain, flywheel driving system.For the energy normal turn, rear axle only rigidly fixes with a wheel, and another is taken turns can only be along with the passive rotation of advancing of car.So in fact, drive wheel has only one, and single riding sailed very effort, and two trailing wheel unbalance stress, also overturns easily during turning.CN2042048U provides a kind of block form two-person tricycle.Can doublely ride, improved the speed of a motor vehicle, but do not solve the problem of two trailing wheel unbalance stress, and can only by people's controlling party to, also increased a tween drive shaft.

The purpose of this utility model be to provide a kind of can be by double co-operative control direction, two trailing wheels are as drive wheel, without tween drive shaft, driving safety labour-saving double pedal three-wheel vehicle.

The utility model is achieved through the following technical solutions: a kind of double pedal three-wheel vehicle, mainly form by front and back wheel, 2 handlebars, 2 vehicle seats and 2 cover pedal-wheel disc-chain-flywheel driving systems.In the preceding threeway (2) of car, horizontal front cross rail (3) is housed, hinged 2 the T shape handlebars in the two ends of front cross rail (3) (4), there is 1 curved boom that stretches out forward (5) lower end of handlebar (4), 1 swivel arm (7) is fixed in the upper end of front fork (6), swivel arm (7) all the time and front fork (6) is synchronous rotates, and the front end of curved boom (5) and swivel arm (7) are hinged with connecting rod (8).Rear axle is pegged graft with the semiaxis (9) of 2 equal in length and is constituted, a semiaxis of splicing position (9) end is an outstanding cannon plug, another root semiaxis (9) end is a hollow cylinder, cannon plug just in time is inserted in the hollow cylinder, crop rotation is rigidly connected behind the other end of 2 semiaxis (9) each and 1, and 2 semiaxis (9) can relatively rotate.2 flywheels (15) are fixed on 2 semiaxis (9) symmetrically.Each fixes 1 brake wheel (21) to 2 semiaxis (9) by splicing position one end, and 2 brake wheels (21) are relative, and brake rubber block (20) and braking vane (19) wrap on the outer rim of 2 brake wheels (21).

The utility model is described in further detail below in conjunction with embodiment of the present utility model.

That Fig. 1 and Fig. 2 show is same embodiment, only compartment partial shape difference.Fig. 3 is the utility model running part constructional drawing.Vehicle frame (1) is made by 2 layers of iron pipe welding, and anterior middle-end all is welded in the preceding threeway (2), and the upper strata pipe of vehicle frame (1) forms front cross rail (3) at front end, and 2 T shape handlebars (4) are hinged on front cross rail (3) two ends.Front fork (6) passes preceding threeway (2).Semiaxis (9) is 2 isometrical isometric steel pipes, wherein is inserted into the external diameter intubate (14) identical with the internal diameter of semiaxis (9) steel pipe in the semiaxis (9), and 2 semiaxis (9) are pegged graft and formed rear axle.2 semiaxis (9) are positioned on the vehicle frame (1) by bearing (10), and two ends and trailing wheel (11) are fastening with captive nut (12).

Two people respectively step a cover driving system when riding.Each one had firmly reduced half when two people exerted oneself synchronously.When needing turning, as long as wherein a people rotates handlebar, can pass through curved boom (5)-connecting rod (8)-swivel arm (7)-front fork (6) and drive front-wheel (13) turning, the people who is in side this moment exerts oneself, and car gets final product normal turn.

The utility model can be made the compartment of back varied.Be used for shipping and can increase load carrying ability, laborsaving and pick up speed.It is very light and handy, convenient to be used for tourism, also can make the two-man event vehicle.Because double rear wheel drives, as long as two people are harmonious, each stress equalization, it is very safe to ride.The utility model handlebar has adopted connecting rod one crank driving mechanism, and two people are easy to accomplish good teamwork when handling, and improves the speed of a motor vehicle and also can not cause danger.
