Description

Tricycle with casing

The utility model relates to a kind of sedan-type cycle, it belongs to and is specially adapted for rider in the communications and transportation and drives the trackless terrestrial vehicle of sailing voluntarily.

Existing two-wheeled cycle, the vehicle body height, no outer cover, stability, seek shelter from wind and rain and sun-proof property poor.A kind of four-wheel sedan-type cycle is disclosed among Chinese patent CN 87 2 13216U, its formation is the distribution that assumes diamond in shape of bicycle four wheels, the front and back two-wheeled is a road wheel, there are two balance steamboats that can stretch both sides, its weak point is, in fact have only two wheel walkings, two side wheels just stretch out and land when parking, startup.Owe steady, dangerous when therefore travelling.The operator is back and forth stepping of pin during driving, though speed can increase, when meeting the road surface gradient being arranged, travels difficulty will take place.

The utility model is to avoid above-mentioned deficiency of the prior art and proposes a kind of safety and stability of both can having sought shelter from wind and rain, and is fit to attractive in appearance, the light sedan-type cycle of the on and off duty and out on tours of city worker.This car outer cover can be dismantled voluntarily according to user's needs and seasonal variation, owing to adopt the transmission of three-wheel secondary, center of gravity is low, not only improves walking stability, and laborsaving during the manpower pedal, and the rear portion also is provided with child's seat stool in the car.

General sedan-type cycle is made up of the wheel that travels, driving device, steering hardware and car cover, this car characteristics be travel the wheel be three wheels, distribution triangular in shape, except that front-wheel, whole vehicle body is enclosed within the car cover, and car cover and railway carriage chassis are detachable by bolts assemblies, and driving device is the secondary transmission, sedan-type cycle has the reversing gear that is installed on the car shell skeleton, and is provided with arrangement of clutch.The reversing crank is free to rotate on rocking handle, and rocking handle passes slide block and connects the reversing dish.The braking spanner is fixed on the axle by bolt connection piece, lever connection one end connects the braking spanner, the other end is connected with trammel beam, the trammel beam two ends connect two brake pulling wires (being generally two steel ropes gets final product) respectively, and two brake pulling wires are connected with two clamping handles respectively by two pulleys.The car cover material of sedan-type cycle can be iron sheet or plastics are made, and door is installed, window is easy for going up and down.The car cover is streamline contour, and resistance is little, and car is the stiff formula steering hardware of horse, bearing circle is fixed on the steering wheel shaft, and two pull bar one ends and steering wheel shaft external diameter are connected and fixed, and the other end is connected with preceding fork shaft external diameter, pull bar is formed movable parallelogram with preceding fork shaft and steering wheel shaft, as shown in Figure 6.The reversing gear of car is installed on the car cover skeleton, and is provided with arrangement of clutch, and it comprises the box-like groove that is fixed on the skeleton of car cover right side, and interior dress slide block can be dynamically connected with the reversing crank, and an end has spring in the groove, and the other end is equipped with locking tongue and spring.The rear portion is provided with child's seat stool in the car, and four bench legs are screwed on passenger-car chassis.

Wherein: fork shaft before the 1-front fork axle sleeve, 2-, 3-steering track rod, 4-steering wheel shaft, the 5-bearing circle, 6-car cover, 7-is seat by bike, child's 8-bench, the 9-left rear wheel, chassis, 10-compartment, the right front gear wheel of 11-, 12-rear axle, the 13-rear flywheel, 14-rear chain, 15-off hind wheel, the left front gear wheel of 16-, chain before the 17-, the 18-cant beam, 19-drives large toothed disk, 20-pedal groove, 21-pedal and crank, 22-front-wheel, the 23-crank of moveing backward, the 24-crank of moveing backward, 25-reversing dish, the box-like groove of 26-, 27-locking tongue, 28-spring, 29-slide block, the 30-spring, 31-brakes spanner, 32-anchor shaft, the 33-lever connection, 34-trammel beam, 35-brake pulling wire, the 36-brake pulling wire, 37-clamping handle, 38-clamping handle, 39, the 40-pulley, 41-trammel beam axle, 42-car shell skeleton.

The advantage of this sedan-type cycle is: compact overall structure, and transmission mechanism is simple and reliable, and steering is flexible, and low-drag cowl is handsome in appearance, and resistance is little, and vehicle body is low, and safety and stability can be sought shelter from wind and rain, winter protection, sun-proof. Can carry small children or loading, be fit to that the city worker is on and off duty to ride, also can be used for tourism. This car overwhelming majority member is present ordinary bicycle general part, is fit to a large amount of production.

Below in conjunction with a description of drawings embodiment of the present utility model:

Three wheels of this sedan-type cycle are triangularly arranged, front-wheel is one of 26 cun cycle wheel, trailing wheel is equivalent to 2 of 28 cun cycle wheels, long 1.9 meters of whole vehicle body, high 1.4 meters, integrated streamlining can be with iron sheet or plastic production, and scribbles conspicuous beautiful color, car cover and chassis are detachable with bolts assemblies, and whole locomotive body all is closed in the car cover except that front-wheel.Be equipped with door, window and Windshield on the car cover, can stretch out one's hand signal from vehicle window during turning.The height of seat (7) is a little more than the axle that drives large toothed disk (19), the distance of the leading edge of seat (7) and driving large toothed disk is longer than the length of foot-operated crank (21) slightly, the horizon angle of seat midway location and large toothed disk is 15 °～25 °, the power that steps downwards that becomes ordinary bicycle is into stepping the most comfortable, laborsaving forward near level.When the operator drives, earlier pedal on the pedal (21) is driven preceding chain (17) by driving large toothed disk (19), right front gear wheel (11) and left front gear wheel (16) coaxial and that be fixed on the axle thereof are rotated, drive rear chain (14) and rear flywheel (13), left rear wheel (9) is rolled, and car marches forward.The slide block (29) of will moveing backward during reversing is pulled backward, reversing dish (25) is contacted closely with off hind wheel (15), locking tongue (27) is upspring under spring (28) effect, make the slide block (29) can not reposition, pull reversing crank (23) by reversing crank (24), the reversing dish is rotated, the reversing dish contacts closely with off hind wheel (15), drive off hind wheel and roll forward, car is gone backward.Depress locking tongue (27) reversing slide block (29) when reversing finishes and under spring (30) effect, move forward, reversing dish (25) and off hind wheel (15) are disengaged.When sedan-type cycle needs glancing impact, at first pull the braking spanner (31) that is fixed on the axle (32), drive trammel beam (34) forward by pull bar (33), drive the pull bar line (35) (36) that links to each other with trammel beam simultaneously forward, pull clamping handle (37) (38) two-wheel is braked simultaneously.Because of being pulley with the joint of pull bar (33) backguy (35) (36), trammel beam (34) is connected, so, two-wheeled is braked simultaneously by changing the pulling force that angle gets final product automatically regulating (35) (36) that tilts forward and back of trammel beam (34).Sedan-type cycle adopts the travel direction of the stiff formula steering hardware control of horse car, pull bar (3) the pulling preceding fork shaft (2) of chaufeur usable rotational direction dish (5) by linking to each other with steering shaft (4).Form movable parallelogram between them, as shown in Figure 6, make the wheel that travels change to drive and sail direction.
