Abstract

The utility model relates to a lateral turnover resisting rear-mounted tricycle, which comprises a tricycle frame, a tricycle body, a front driving wheel and rear wheels and is characterized in that a beam is fixedly installed under the tricycle frame, two sides of the beam are connected with the rear wheels through a lateral turnover resisting rear wheel support device, and the rear wheels are respectively provided with inside-toward inclined angles so that the wheels on two sides form a splayed structure. Through the design of the structure, the lateral turnover rear wheel support device of the tricycle can absorb certain force during the driving process so as to reduce the feeling of overturning and improve the stability of the whole tricycle. More importantly, the lateral turnover resisting rear-mounted tricycle can be matched with the rear wheels in splayed distribution so that the opening angle of the lower ends of the two rear wheels can change along with the changing of the degree of force when the rear wheels suffer from large force or turn, accordingly the turnover trend to the tricycle body from a centrifugal force is remitted, the stability of the tricycle can be improved, the consequence caused by turnover of the tricycle can be effectively reduced, and riding comfortableness of users is improved.

Description

The rear-mounted three-wheel vehicle of a kind of anti-rollover

Technical field

The utility model belongs to three-wheel vehicle manufacturing technology field, particularly relates to the rear-mounted three-wheel vehicle of a kind of anti-rollover.

Background technology

At present, two same axle mountings of trailing wheel of manual tricycle or electro-tricycle, and through a wheel shaft driving; Three-wheel vehicle because of car load gravity produces big centnifugal force, causes the trailing wheel that changes the outside pressure that contacts to earth to increase when turning; The inside rear wheel pressure that contacts to earth reduces, and therefore makes car body produce bevelled trend, bicyclist's health that must tilt to the inside; With the centnifugal force of opposing car body, the bicyclist feels under the weather, and the panesthesia car will turn over; People should have an intimate knowledge in daily life, and it is not obedient more to want to stand up body more.For the electro-tricycle of rapid speed, during especially heavily loaded sharply turning, tilt also is difficult to overcome the centnifugal force of car body in the human body, and vehicle body is tumbled, and causes traffic accident.In addition, three-wheel vehicle is advanced rugged when overturning the road surface, and two frequent unbalance stress of trailing wheel cause vehicle body swing, vibration, and the rider is also very uncomfortable.

Summary of the invention

The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, cost is low, easy to make, ride more steadily, operation is the rear-mounted three-wheel vehicle of anti-rollover more flexibly.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:

The rear-mounted three-wheel vehicle of a kind of anti-rollover; Comprise vehicle frame, car body and front drive wheel and rear wheel; It is characterized in that: the below of said vehicle frame is installed with crossbeam; The both sides of said crossbeam connect rear wheel through wheeled support device after the anti-rollover, and said two rear wheels are provided with the inclination angle respectively to the inside, make the both sides wheel become the splayed structure.

The utility model can also adopt following technical measures:

Wheeled support device mainly comprises a framing formula swing arm after the said anti-rollover, and an end of said each frame-type swing arm is hinged through arm shaft and crossbeam, and the other end of said frame-type swing arm connects the rear wheel pivot shaft through coupler; Between said two frame-type swing arms and the vehicle frame respectively activity line of centers bevelled spring damper to the inside is installed, the upper end of said spring damper is hinged on the vehicle frame, the lower end of spring damper is hinged on the inboard support of frame-type swing arm.

Advantage and the good effect that the utlity model has are: because the utility model adopts said structure, promptly change traditional trailing wheel coaxial drive, but adopt on the basis of f-w-d; At bottom of frame rollover trailing wheel bracing or strutting arrangement is installed; Carry out the support of rear wheel through wheeled support device after the anti-rollover,, in traveling process, can absorb certain power like this because the employing of the bracing or strutting arrangement of rear wheel is the shock reducing type structure; And then reduce to overturn sensation, improve the stability of car load; The rear wheel of even more important cooperation splayed layout; Receiving perhaps when turning like this; The opening angle of two rear wheel lower ends changes with the size variation of putting forth effort; And then more can improve its stability, actv. prevents that car from turning over the consequence of bringing, but also has improved people's comfort level.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the utility model upward view;

Fig. 3 is the utility model back view.

Among the figure: 1, vehicle frame; 2, car body; 3, front drive wheel; 4, rear wheel; 4-1, pivot shaft; 5, crossbeam; 6, wheeled support device after the anti-rollover; 6-1, the swing arm of framing formula; 6-2, arm shaft; 6-3, coupler; 6-4, spring damper; 6-5, support.

The specific embodiment

For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:

See also Fig. 1 to Fig. 3; The rear-mounted three-wheel vehicle of a kind of anti-rollover; Comprise vehicle frame 1, car body 2 and front drive wheel 3 and rear wheel 4, the below of said vehicle frame 1 is installed with crossbeam 5, and the both sides of said crossbeam 5 connect rear wheel 4 through wheeled support device after the anti-rollover 6; Said two rear wheels are provided with the inclination angle respectively to the inside, make the both sides wheel become the splayed structure.

In the said structure; Wheeled support device is preferably after the said anti-rollover: wheeled support device 6 mainly comprises a framing formula swing arm 6-1 after the anti-rollover; The end of said each frame-type swing arm 6-1 is hinged through arm shaft 6-2 and crossbeam 5, and the other end of said frame-type swing arm 6-1 connects rear wheel pivot shaft 4-1 through coupler 6-3; Between said two frame-type swing arm 6-1 and the vehicle frame 1 respectively activity line of centers bevelled spring damper 6-4 to the inside is installed; The upper end of said spring damper 6-4 is hinged on the vehicle frame 1, and the lower end of spring damper 6-4 is hinged on the inboard support 6-5 of frame-type swing arm 6-1.

Through the design of said structure, the three-wheel vehicle of the utility model structure, wheeled support device can absorb certain power after the anti-rollover in the process of riding, and then reduces to overturn sensation, improves the stability of car load; The rear wheel of the even more important cooperation splayed layout that is; Receiving perhaps when turning like this; The opening angle of two rear wheel lower ends changes with the size variation of putting forth effort, and has alleviated centnifugal force to the trend of tumbling that car body brings, and more can improve its stability; Actv. reduces because of car turns over the consequence of bringing, but also has improved the comfort level that people ride.

The above only is the preferred embodiment to the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model is to any simple modification that above embodiment did; Equivalent variations and modification all belong in the scope of the utility model technical scheme.
