Problems solved by technology
But because its rear axle is the dead axle that is used for assembling, as adopting rear-wheel drive and installing braking device must add complicated transmission part and positioning part, and front-wheel drive is impossible again in fact, so this invention is difficult to implement, more Impossible to solve the rollover problem
The Chinese patent documents No. 98227086.0 and 88201411.0 each disclose a rollover-preventing tricycle. Although this invention can solve the rollover problem to a certain extent, it does not solve the problem of the complicated structure of the ordinary tricycle frame, the large "body shape", The body is bulky, difficult to pack and transport, etc.

Embodiment Construction
[0041] Preferred embodiment: the present embodiment is a light tricycle with shock absorber on the rear axle. As shown in Fig. 9, Fig. 10, and Fig. 14, the light-duty tricycle frame includes a main frame 1 composed of an upper tube 2, a lower tube 3, a front tube 4, and a rear stand The rear axle connecting device 6 at the rear end. Rear axle connecting device 6 adopts groove guide plate+shock absorber type structure, and this device comprises the guide plate 613 of band groove shape section, a pair of left and right side by side shock absorber 63B, 63B ' and link assembly 62. The trough-shaped guide plate 613 is made of 2mm thin steel plate, and the two sides of the rear end are respectively provided with 3 round holes, wherein the middle round hole is matched with the rear axle 9, and the hole diameter is larger than the rear axle 9, so that the rear axle 9 is in it. can run freely, and the remaining two round holes are used to install the following two transverse connectin...

Abstract
The invention relates to a light tricycle, the frame of this tricycle includes the main frame comprised of top tube, low tube, head tube, back riser and rear axle connecting device fixed on back end of the main frame, the rear axle connecting device includes leading truck, connection piece assembly and upright fork or bumper shock absorber. Light tricycle frame structure of the invention is simple, which is small, the weight is light, processing is easy , which is convenient for packing and transportation; Light tricycle assembled by this frame is small and exquisite light, which is difficult to turn over the side, travels stable safely, riding is comfortable, the brake is reliable. Use of this invention is extensive, which can use people's power to drive as the general traffic instrument of riding instead of walk, also can be developed into bassinets, recreational vehicles, exercycles, recreational vehicles, tourist coaches, delivery cars etc., when battery, motor or internal-combustion engine is installed, it can further be assembled to light tricycle electric motor car, light tricycle help-move-vehicle, light tricycle motor vehicle and disabled person's car etc.
Description
[0001] This application is a divisional application of ZL200410027852.6. The application date of the original application is July 1, 2004, the application number is 200410027852.6, and the title of the invention is "a portable tricycle and its frame". 【Technical field】 [0002] The invention relates to a tricycle, in particular to a small and light tricycle. 【technical background】 [0003] When a tricycle travels slowly on a straight road, its stability and safety are better than bicycles, so tricycles are widely used in baby carriages, and are still a common means of transport in some small and medium-sized cities and rural areas. However, the existing tricycle frame structure is complex, the "body shape" is too large, the body is heavy, and the body is easy to roll over when driving on uneven roads and turning quickly. Today, when road resources are scarce, traffic is increasingly crowded, and people's safety awareness is increasing. Tricycles are of course "blocked" in so...
