Problems solved by technology

The disadvantage of the fixed dead flywheel is that it can only rotate forward and backward, but it has no ability to slide in neutral
[0003] In addition, the distance between the two rear wheels of current various tricycles is fixed all the time, and some roads are provided with a lot of piles due to various reasons. easy to pass
Furthermore, if you drive too fast, it will be unstable because the rear wheel spacing is too narrow, which will cause rollover, etc.

Embodiment Construction

[0040] Accompanying drawing is the specific embodiment of the present invention. Such as Figures 1 to 19As shown, this kind of front-drive three-wheeled bicycle includes a front fork 23 and a vehicle frame 1. A front wheel 24 is installed at the lower end of the front fork 23. The rear end of the vehicle frame 1 is a frame 101 with an opening facing the rear. Two ends of the frame 101 are respectively A horizontal sleeve 32 is fixed, and a shaft seat 33 is fixed on each sleeve 32, and a distance-adjusting shaft 34 is set inside each sleeve 33, and the distance-adjusting shaft 34 can freely slide left and right in the sleeve 32, The sleeve 32 plays a guiding role. For the sliding stability of the distance adjustment shaft 34, the sleeve 33 and the distance adjustment shaft 34 can be connected by a spline 321, specifically: a spline 321 is installed in the sleeve 33, A spline groove 341 is opened on the distance-adjusting shaft 34; a rear wheel 31 is installed at the outer end...

Abstract

The invention, which relates to the field of fitness equipment, particularly discloses a front-drive tricycle. The distance between two rear wheels of the front-drive tricycle can be adjusted througha distance adjusting shaft, distance adjusting screw sleeves, a distance adjusting screw cylinder and the like. The driving of the front wheel is realized by a combined wheel shaft structure capable of freely shifting gears for transmission. A driving shaft, an inner cylinder and an outer hub are arranged. The driving shaft is composed of an end plate, a forward rotation wire section, a reverse rotation wire section and a smooth wire section that have outer diameters reduced gradually; clutch baffle plates are arranged on the two rotation wire sections; the inner cylinder is sleeved on the driving shaft and is internally provided with two clutch check rings, a clutch check disc on the forward rotation wire section is arranged between the two clutch check rings; the smooth wire section matches a smooth rotary disc provided with a traction fork, the traction fork is inserted into the two clutch check rings, a fixed rotation stopping disc is arranged outside the smooth rotary disc; and the outer hub sleeves the outside of the inner cylinder. The tricycle can rotate forwards or can also rotate reversely.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a front-drive tricycle. Background technique [0002] The rear track of the front-drive tricycle of the prior art is fixed and difficult to adjust. Most of the front-drive tricycle wheel axles use a dead flywheel shaft structure, or a small number of live flywheel shaft structures. The disadvantage of the ratchet type live flywheel is that it can only rotate forward and slide forward, but it has no ability to reverse and retreat. The disadvantage of the fixed dead flywheel is that it can only go forward in forward rotation and backward in reverse rotation, but it has no ability to slide in neutral. [0003] In addition, the distance between the two rear wheels of current various tricycles is fixed all the time, and some roads are provided with a lot of piles due to various reasons. Good pass. Furthermore, if you drive too fast, it will be unstable because the rear wheel spacin...
