Abstract

The utility model discloses a low saddle bicycle with a driving means in a front wheel and a steering means behind, which is composed of a bicycle frame, wheels, a mud guard, a front wheel frame, a rear wheel fork, a saddle, bicycle handlebars, a bevel gear, a transmission shaft, a chain disk, pedals, wheel shafts, a fly wheel, a gap bridge chain disk, a centre shaft, a chain, etc. The utility model not only has the advantages of simple structure and low center of gravity, but also has the advantages of stable steering, stable walking by bicycle, safe utilization, etc. due to the adoption of the structure of front driving and rear steering and bevel gear drive steering.

Description

Turn to low seat bicycle behind the before driving

The utility model turns to low seat bicycle after relating to a kind of before driving, belongs to the bicycle field.

At present, bicycle great majority of the prior art all are the structures that turns to before the rear drive, the shortcoming of this structure is to need orthostatism by bike by bike the time, this not only resistance greatly, by bike the effort, and center of gravity height, unstable by bike, fall easily, so the bicycle of steering structure is still not ideal enough in use before this rear drive of the prior art; But and turn to the bicycle complex structure behind the before driving of the prior art, and center of gravity is also less than reducing, so still do not accepted by people.

The purpose of this utility model is: provide a kind of simple in structure, center of gravity is low, before driving, after the bicycle that turns to.

The utility model is to constitute like this: it is by vehicle frame (1), wheel (2), mudwing (3), front wheel carrier (4), rear wheel fork (5), seat (6), bicycle handle bar (7), bevel gear (8), transmission shaft (9), big chain plate (10), pedal (11), wheel shaft (12), flywheel (13), gap bridge chain drum (14), (15), axis (16), chain (17), (18) wait other to form by parts, vehicle frame (1) is the U-shaped vehicle frame, end at U-shaped vehicle frame (1) is fixed with front wheel carrier (4), the other end at U-shaped vehicle frame (1) is equipped with rear wheel fork (5), wheel (2) is installed in respectively on front wheel carrier (4) and the rear wheel fork (5), seat (5) is fixed at the bottom of the middle part of U-shaped vehicle frame (1) on the whippletree, bicycle handle bar (7) is contained in vehicle frame (1) and upward and by bevel gear (8) is connected with rear wheel fork (5) with transmission shaft (9), big chain plate (10) and pedal (11) are fixed on the wheel shaft (12), flywheel (13) is fixed on the front vehicle wheel (2), gap bridge chain drum (14), (15) be separately fixed at the two ends of axis (16), chain (17) is enclosed within on big chain plate (10) and the gap bridge chain drum (14), and chain (18) is enclosed within on flywheel (13) and the gap bridge chain drum (15).

The utility model compared with prior art not only has simple in structure, underslung advantage, and owing to adopted the structure that turns to behind the before driving with the bevel gear transmission turning, so also have the advantage such as steady, safe and reliable that turns to surely, walks by bike.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the birds-eye view of accompanying drawing 1.

Embodiment of the present utility model: wheel (2), mudwing (3) can adopt finished product of the prior art, other other parts are special purpose parts, vehicle frame (1) is made the U-shaped vehicle frame, front wheel carrier (4) makes leg-of-mutton structure, front wheel carrier (4) is fixed on one side of U-shaped vehicle frame, load onto rear wheel fork (5) at the other end of U-shaped vehicle frame (1), wheel (2) is installed in respectively on front wheel carrier (4) and the rear wheel fork (5), seat (6) is fixed at the bottom of the middle part of U-shaped vehicle frame (1) on the whippletree, bicycle handle bar (7) is contained in vehicle frame (1) and upward and by bevel gear (8) is connected with rear wheel fork (5) with transmission shaft (9), big chain plate (10) and pedal (11) are fixed on the wheel shaft (12), flywheel (13) is fixed on the front vehicle wheel (2), axis (16) is contained in the bottom of U-shaped vehicle frame (1), gap bridge chain drum (14), (15) be separately fixed at the two ends of axis (15), chain (17) is enclosed within on big chain plate (10) and the gap bridge chain drum (14), and chain (15) is enclosed within flywheel (13) and gap bridge chain drum (15) and goes up.
