The utility model discloses a kind of before driving rear steering and roll self-equalizing tricycle, it has, and vehicle body is low, stability and safety good, comfortable, steady, ride for a long time and can not feel the feature such as tired, the people being applicable to all ages and classes rides.It comprises rear steering mechanism, seat equalizing gear, vehicle frame, Chain conveyer speed-changing mechanism.Pedal and gear teeth wheels are positioned on the support of front-wheel oblique upper, provide power by Chain conveyer to front-wheel; Two trailing wheels utilize vertical shaft to be arranged on vehicle frame respectively, and chair mounted, on vehicle frame and crossbeam, is equipped with balance spring under seat, keep seat comfort to stablize; Turn to and controlled by steering handwheel, spur link rod mechanism; Turning wing drop turns to pull bar to realize by the vertical shaft being connected to vehicle frame side.The utility model both can be used as the general vehicle and had used, and also can be used as leisure, exercise kit uses.
Description
Technical field
The utility model relates to technical field of transportation means, and specifically, it is that a kind of before driving rear steering rolls self-equalizing tricycle.
Background technology
Bicycle, because of flexible, cheap, loading of can riding instead of walk, can be taken exercises again, so no matter be in cities and towns or in rural area, it is all enjoy people to like and one of widely used vehicle.
Traditional bicycle structure known by people, i.e. rear drive, two-wheeled, wushu front steering.For a long time, people have done a large amount of Curve guide impeller in the configuration aspects of bicycle, as Chinese patent 03257252.2,03216859.4,02294409.5 respectively disclosed in exempt to pedal hand-drive bicycle, spring booster bicycle and wheel transmission and accelerate to drive bicycle, type of drive, speed-changing mechanism, laborsaving etc. in done a lot of technological improvement, but do not change the structural pattern of standard bicycle.In comfortable leisure, Chinese patent 03232946.6,03257220.4 also discloses two kinds of leisure booster bicycles and front-driven rear-steering bicycle, these two kinds of bicycles, the former except using front-wheel as drive wheel, increase except backrest after common saddle, be still two wheel constructions; The latter, car body is made up of two-wheeled, front cant beam, rear cant beam, crossbeam, front driving mechanism and steering hardware substantially, steering swivel system is then comparatively complicated, handlebar, connecting rod, universal-joint, quadrant gear, adjustment bolt etc., not only add the cost of bicycle, also bring inconvenience to use technology.
In a word, no matter be bicycle common at present, or the bicycle after technological improvement, its two-wheeled, wushu such as to turn to keep so far at the most traditional, the basic version always.So, bicycle is concerning bicyclist, although through certain learning process, can expertly grasp its balance method, but weigh from the scope of comfortable, steady, safe angle and comfortable use crowd, the version of bicycle still also exists some shortcomings, is also easy to cause user tired when riding for a long time.
Summary of the invention
The purpose of this utility model is exactly change the structural pattern of standard bicycle, provides a kind of good stability, comfortable, as long as its physical dimension of corresponding change, can adapt to the before driving rear steering that any age bracket crowd uses and roll self-equalizing tricycle.
The purpose of this utility model is achieved in that before driving rear steering rolls self-equalizing tricycle and comprises rear steering mechanism, seat equalizing gear, vehicle frame, Chain conveyer and speed-changing mechanism, wing drop mechanism.It is characterized in that: pedal (2) and gear teeth wheels (1) and front-wheel (3) coaxial package are on vehicle frame (4), two trailing wheels (8) utilize vertical shaft (9) to be arranged on vehicle frame (4) respectively, crossbeam (18) is provided with between the transverse direction of two vertical shafts (9), headrest (22) balances bearing pin (21) and connects with utilizing between seat adjustment backrest (7), seat (7) is arranged on vehicle frame (4), steering handwheel (5) is positioned at under-seat, steering gear axle (13) is connected on vehicle frame (4), straight-tooth (15) is connected with connecting rod (12), end with pin shaft joint on vertical shaft (9), be used for control by spur link rod mechanism to turn to.Between vehicle frame (4) and crossbeam (18), spring (20) in being equipped with back, two retracing spring (20) one end hang on vehicle frame (4), and the other end is hung on the crossbeam (18) of roll axis (19) left and right sides.In returning, lock banking stop (17) is welded on vehicle frame (4) roll axis (19) and is connected to crossbeam (18), and in returning, mechanical brake (16) is fixed on crossbeam (4).
Compared with prior art, because the utility model has three wheels, vehicle body low, so its stability and safety are more good, are more suitable for different crowd and ride; Seat and balance spring, before driving and handle type rear steering structure can make bicyclist feel more comfortable and steady, ride for a long time in time and also can not feel tired.In addition, structure of the present utility model is also uncomplicated, and novel in appearance is attractive in appearance, and cost is substantially suitable with existing bicycle.

Detailed description of the invention
Embodiment 1:
The parts such as front and back wheel 3 and 8 of the present utility model, pedal 2, chain drive and gear teeth wheels 1 can utilize the parts used in prior art, and brake is rack-mount equally.Headrest 22 balances bearing pin 21 and connects with utilizing between seat adjustment backrest 7, can make to ride more steadily, and when particularly turning, human body can vehicle body swing relatively, avoids the effect of centnifugal force to human body.Turn to and rely on steering handwheel 5, to transfer example to the right, during right-hand turning, right-hand turning steering handwheel 5, engaged by straight-tooth 15, drivening rod 12 travels forward, and pulls right back wheel shaft with vertical shaft 9 for center of circle clockwise oscillation, tierod 10 on right back wheel shaft drives left rear wheel clockwise oscillation, completes right-hand rotation action.While turning, vehicle frame is released by inclination pull bar 11 on right back wheel shaft to the left, and car body is tilted to the right, and after having turned, under the effect of retracing spring 20 elastic force, car body automatically resets.Counter-rotation steering handwheel during left-hand rotation.
Embodiment 2:
Balance headrest also can adopt the support of semicircle or other shapes to replace, as long as ensure that seat 6 relative frame 4 can swing.
Embodiment 3:
According to different design philosophys or different motor habits, pushing away of steering hardware, draws or swaying direction can solve by increasing the method arranging connecting rod.
