Description

Miniature sedan-type cycle

The utility model relates to a kind of miniature sedan-type cycle.

Since Frenchman west furac invention bicycle in 1790, through updating, bicycle can be said very perfect over more than 200 year.It is small and exquisite, light, simple in structure, the city is not polluted, and is cheap, has become the important walking-replacing tool of urban and rural residents.But bicycle is made up of two wheels, turns to handlebar control, and the whole body center of gravity drops on the slight triangular form saddle, in middle deficient in stability, traveling comfort and the safety of riding when driving.Though existing quadricycle patent has been avoided above some shortcoming, great majority adopt the rotary driving of shedding cam, though this mode is simple and reliable, it is big to take up room, and effective travel is short, and the both legs amplitude of fluctuation is big.Though patent 91203171.9,95222420.8,95224204.4,96238537.9 has adopted the pedal reciprocation type driving, but common ground all is to drive chain (or pull bar) by treadling, use chain (or pull bar) to drive ratchet (or escapement) again, rather than directly with dynamic action in ratchet, make actuating device still show complicated, add the part system be provided with unreasonable, thereby cause full car body long-pending bigger inevitably.In today that traffic is crowded day by day, whether a quadricycle patent has marketable value, and its volume is the problem of a key, and this just requires on general design and local device new breakthrough to be arranged.

The purpose of this programme is to invent that a kind of length, actuating device that merges bicycle, four-wheeled is simple, volume is little, takes safety and comfort, convenient driving and have the miniature sedan-type cycle of similar automobile partial function.

For achieving the above object, the utility model is made up of vehicle body, each two wheel of front and back, steering hardware, engine installation, brake equipment, steering hardware is made up of bearing circle, pipe link, steel cable, steering track rod, spindle arm again, engine installation is made up of pedal, connecting arm, ratchet, speed change drive sprocket set, speed change driven chain wheels, diff again, the bearing circle that is located at vehicle body operator's compartment front end and pipe link are for captiveing joint, the spindle arm and the steering track rod that link to each other with front vehicle wheel are hinged, and steering track rod is connected by steel cable with pipe link; The axle drive shaft that is installed in body structure is equipped with speed change drive sprocket set, two ratchets, left and right sides pedal is hinged with the connecting arm that is fixed on the two ratchet outer rings respectively, connect by the guiding principle rope between the pedal of the left and right sides, the driven shaft that is located at the vehicle body middle part is provided with speed change driven chain wheels, reversing gear; Be connected for chain between hinge wheel between speed change drive sprocket set and the speed change driven chain wheels, on the driven shaft and the diff.

The bottom of the pipe link on the utility model steering hardware is hinged on the vehicle body, the bearing in the middle of the slide block is passed in the upper end, slide block is fixed on the U type fixed mount of captiveing joint with vehicle body by check screw, pipe link is provided with knock hole, be provided with 2-5 and the corresponding jack of knock hole in bearing circle on the axle, shaft extension is gone in the pipe link mode that penetrates knock hole and jack by governing screw and is fixed in the bearing circle.

The further improvement project of the utility model is: reversing gear is made up of platen, shift fork, pull back spring, rocking arm, reversing pull lever, platen is located at the side of hinge wheel, shift fork is hinged on the vehicle body, the one end inserts in the draw-in groove of platen, the other end and pull back spring are connected with steel cable with reversing pull lever interlock, and rocking arm is hinged on the platen.

Another kind of improvement project of the present utility model is: engine installation is provided with speed increasing mechanism, this speed increasing mechanism by the speedup main shaft be contained in it above big gear wheel, two ratchets, speedup rocking bar, the tween drive shafts of captiveing joint with the ratchet outer ring, be installed in intermediate gear and the sprocket wheel on the tween drive shaft, the speedup ratchet that is located on the axle drive shaft is formed, big gear wheel is meshed with intermediate gear, is connected for chain between sprocket wheel and the speedup ratchet.

Compared with the prior art, the utlity model has following several advantage:

1, the pedal reciprocation type motion drives the actuating device of ratchet one-way rotation, and is simple in structure, laborsaving, occupies little space, and the vehicle body volume can be dwindled greatly, because pollution-free, the utility model is promoted in the city becomes possibility simultaneously.

2, drive easily, travel steady, safety are added adjustable wheel steering device, and the crowd that can be fit to all ages and classes uses.

3, be provided with speed increasing mechanism, transmission system and differential gear, the speed of a motor vehicle is per hour brought up to more than 40 kilometers, be applicable to multiple functions such as city traffic and jaunt, leisure, body-building.

4, most of parts can and bicycle general, practicable assembly type production in enormous quantities.
