Abstract

The utility model relates to an inclined type tricycle used for the ride of two persons, comprising wheels, wheel carriers and the incline system, wherein, the incline system is composed of a bearing frame, a plurality of bearing seat s, a spacing plate and limiting springs. The utility model which is light has the advantages of reasonable structure and stable riding, and materials are saved.

Description

Inclined type tricycle

The utility model relates to a kind of double compact tilt type tricycle that drives.It is to be made of wheel, vehicle frame and pitch system.Belong to the tricycle class.International classification number is: B62K5/02.

Two wheels before and after existing bicycle is generally, therefore less stable in the process of riding, and band people loading is also inconvenient.China's utility model patent CN88200549.9 number discloses the horizontal weather proof three-wheel vehicle of a kind of apsacline.This three-wheel vehicle is by strand coupling spindle 4 even is continuous with bearing frame 7 with it with vehicle frame 1, there are two bearings 5,6 to be individually fixed in bearing frame 7 vertical two ends on the coupling spindle 4, axle bearing 17,18 is individually fixed in bearing frame 7 transverse ends after two, and is connected with spacing extension spring 11,12 between coupling spindle 4 and bearing frame 7.This kind three-wheel vehicle has the fixedly vehicle frame identical with ordinary fixed type three-wheel vehicle, and vehicle frame can be that the center tilts to the left or to the right with coupling spindle 4.It has, and the rear wheel rotation square is short, vehicle body is narrow, center of gravity is low, vehicle body is short, advantages such as front shroud and hood can be installed.But because its coupling spindle 4 is long, occupy the certain space of bearing frame 7, both wasted material; Be unfavorable in bearing frame installing other device again, as motor drive mechanism etc.; In addition, the installation site of restriction extension spring is not too reasonable, influences the compactedness of its structure.

The purpose of this utility model is just in order to solve weak point of the prior art, and proposed a kind of double compact tilt type tricycle that drives.This tricycle except possessing advantage of the prior art, also have saving in material, rational in infrastructure, drive advantages such as stable.

The purpose of this utility model is achieved in that the apsacline tricycle, its pitch system be the postmedian of a bearing frame fix two with car after axle bearing bonded assembly bearing seat; At the front end of bearing frame a tail end bearing bonded assembly bearing seat with vehicle frame is installed; Fix one in the rear end of bearing frame and connect axle bed, axle bed is connected with back vehicle frame bearing.By this device, when tilting of car body, vehicle frame can coupling spindle be that the center tilts to the left or to the right.

The utility model can also be further perfect by following steps:

Between bearing frame and back vehicle frame, elastic limit device is housed.In order to the angle of inclination of restriction car body, and help car body to shift to recovery when directly advancing from revolution.Thereby reach the stable purpose of riding.This inhibiting device can be realized with spring.

The utility model has three width of cloth accompanying drawings, wherein:

Fig. 1, be the utility model tilting of car body scheme drawing, be most preferred embodiment of the present utility model, also can explain the accompanying drawing of book extract;

Fig. 2, be front elevation of the present utility model;

Fig. 3, be the constructional drawing of the utility model medium dip system.

Below in conjunction with drawings and Examples the utility model is further described:

Most preferred embodiment of the present utility model is installed a pitch system at common vehicle frame tail end as shown in Figure 1, and its structure is welded a positioning plate 3 in back vehicle frame 2 lower horizontal, as shown in Figure 3 at connecting strap 8 of the middle part of positioning plate 3 solid welding.The bearing of two coupling spindles, being installed on bearing frame 1 vertical two ends is on the bearing seat 11 and 7 of front-end and back-end; Two rear axle bearing installations are on the bearing seat 5 and 10 at the middle part at the horizontal two ends of bearing frame 1.Two coupling spindles are connected with the connecting strap 4 of vehicle frame tail end with vehicle frame 2 bottoms, back respectively.Vehicle frame is rotated for 1 one-tenth by coupling spindle and bearing frame to be connected.Thereby realize the inclination of car body.If consider from damping performance, also can be between back vehicle frame 2 and bearing frame 1 mounting shock absorber, or below bearing frame 1, install the damping chain stay additional, with the rear axle bearing fixing on the damping chain stay, to reach the purpose of damping.Two limit spring 14 and 9 are installed between the positioning plate 3 of vehicle frame bottom and bearing frame 1.Spring 14 and 9 plays the booster action of restriction and answer in coupling spindle and bearing frame counter motion.If consider from the performance of spring, limit spring can adopt compression spring, extension spring or torsion spring.

Type of drive of the present utility model adopts foot-operated crank throw chain drive, also motor driving device can be installed, and also can adopt simultaneously in two ways.

The utility model compared with prior art, have rational in infrastructure, light, save material, driving safety, the advantage such as steady.
