Abstract

The utility model relates to a side tricycle which is the retrofit of a common bicycle, comprising the bicycle, a side seat and side wheels. The side seat is connected with the common bicycle through a front supporting rod and a rear supporting rod, one end of a connecting rod is connected to the upper part or the middle part of the rear supporting rod through a hinge, and the other end of the connecting rod is connected with the side wheels through fixed plates; besides, the fixed plates are connected with a chassis through the hinges. The utility model has the advantages that the stability is high when the side tricycle is driven ahead; especially, the disadvantage that the bicycle is easily overturned while turning is overcome, the side wheels can play the corresponding incline when the side tricycle is inclined, and the frictional resistance between the side wheels and the ground is lessened; the position of the chassis is low, and the safety of loading people and articles is raised.

Description

Sidetricycle

The utility model relates to a kind of limit tricycle that can be converted by ordinary bicycle.

Have the people that common two wheel bicycles are repacked into the limit tricycle at present, its cincture axle and main back wheels of vehicle axle are connected as a single entity, and this captive joint makes cycling stiff, and poor stability especially easily overturns when its right-hand corner.Cycling has deflection often, and cincture is fixed, thus cause cincture laterally to slide to ride painstaking and wear on tyres serious.This car is after the side seat load-carrying, and depression appears in cincture and main shop, and main car Right deviation is accelerated each member wearing and tearing.This car side seat chassis is on main back wheels of vehicle axis, and its center of gravity is too high, and is manned, loading is dangerous.

The purpose of this utility model provides a kind of limit tricycle that can be converted by common two wheel bicycles, and its side seat and main car adopt and flexibly connect, and increase stability, and cincture can tilt with the inclination of main car, reduces the side seat chassis, improves safety.

The utility model comprises common two wheel bicycles, side seat and cincture, its difference is to be fixed with front support rod on the bicycle tripod, the bicycle rear bracing frame is fixed with back support rod, the side seat chassis is hinged through the hinge to the lower end of back and front supporting bar, pipe link one end is connected to back support rod middle part or top by hinge, another termination adapter plate, adapter plate links to each other with the chassis by hinge, and the cincture axle is fixed on the adapter plate.

Main car of the present utility model and cincture adopt hinge to be connected, and have overcome the original limit tricycle stiff shortcoming of riding, and have improved the stability of car, and master's car can freely tilt when particularly turning, and can not overturn.Cincture adopts hinge to be connected by adapter plate and pipe link and main car, can corresponding thereupon inclination when main car deflection, reduced the friction drag between cincture and ground.The side seat chassis is connected in the lower end of back and front supporting bar, and center of gravity is low, has strengthened safety manned, loading.

Fig. 1 is the connection diagram of back and front supporting bar.Wherein front support rod 1 upper end is fixed on the bicycle crossbeam, and before the middle part is fixed in U-shaped card 2 on the cant beam, back support rod 3 is fixed in behind the bicycle on the cant beam and cross sill by U-shaped card 4,5.

Fig. 2 is the utility model birds-eye view.

Fig. 3 is side seat, cincture scheme drawing.

Fig. 4 is pipe link, adapter plate, chassis connection diagram.

Connecting rod on the chassis 6 is connected with the lower end of back and front supporting bar by hinge 7,8, and pipe link 9 one ends are connected in the back support rod middle part by hinge 10, and the other end is by adapter plate 11 connection side wheel shafts 13.Pipe link 9 is formed by two sections, wherein one section parallel with cincture, this two intersegmental available hinge connects, and makes cincture more flexible.Seat 12 is fixed on the chassis 6.The chassis is connected with the length-adjustable inside and outside bar structure of the connecting rod employing between the back and front supporting bar, can guarantee that cincture is parallel with main car.

Among Fig. 4, adapter plate 11 adopts hinge to be connected with chassis 6, and the fixed orifice 14 of connection side wheel shaft is arranged on the adapter plate.The cincture of corresponding different-diameter can be established highly different a plurality of fixed orifices and install with convenient on the adapter plate.

Claims (4)

1, a kind of limit tricycle, comprise common two wheel bicycles, side seat and cincture, it is characterized in that being fixed with on the bicycle tripod front support rod 1, be fixed with back support rod 3 on the bicycle rear bracing frame, side seat chassis 6 is connected in the lower end of back and front supporting bar by hinge 7,8, and pipe link 9 one ends are connected in back support rod middle part or top, another termination adapter plate 11 by hinge 10, adapter plate links to each other with the chassis by hinge, and cincture axle 13 is fixed on the adapter plate.

2, by the described bicycle of claim 1, it is characterized in that adapter plate is provided with highly different a plurality of fixed orifices 14.

3, by claim 1 or 2 described bicycles, it is characterized in that pipe link 9 forms by two sections, wherein one section parallel with cincture, these two sections are connected by hinge.

4, by the described bicycle of claim 1, it is characterized in that adopting between chassis 6 and the back and front supporting bar length-adjustable inside and outside the bar structure be connected.
