Abstract
The utility model relates to the technical field of human-power transportation vehicles, in particular to a small folding bicycle comprising a frame, wherein a handlebar is arranged at the top of a stem of a front fork of the frame, and a saddle is arranged at the top of a stem of a rear fork of the frame; wheels are arranged on the front fork and the rear fork of the frame; a driving sprocket and pedals fixedly arranged on the driving sprocket are arranged at the connection part of the rear fork of the frame and the frame; the front and the rear wheels comprise a main shaft, an inner ring, an outer ring, a supporting inner ring and an outer ring spoke; a circular cavity for accommodating an expanding brake device is arranged on the inner ring, and alternatively, an expanding brake device is arranged in the circular cavity; a driven sprocket connected with the driving sprocket via a transmission mechanism is arranged on one side of the inner ring of the rear wheel; and the inner ring, the outer ring and the spoke are integrally formed with aluminum materials. The small folding bicycle has the advantages of light weight, long service life and distortion and contortion resistance; and the small folding bicycle is equipped with a wear-resistant supporting expanding brake device, thereby ensuring the safe use.
Description
Technical field
The utility model belongs to the technical field of transportation means of travelling by the manpower driving, refers in particular to a kind of small foldable bicycle.
Background technology
The wheel that is provided with by main shaft on existing bicycle front fork and the back vent is generally by the axle skin, aluminium, steel ring and spoke are formed, side at cycle wheel is provided with the coating brake gear, this class bicycle exists the some shortcomings part: 1, the outer rim of cycle wheel is subjected to the easy torsional deflection of the bigger extruding of weight, influences the normal use of bicycle; 2, period of service is of a specified duration, and aluminium, steel ring take place to be offset to reverse aluminium, steel ring are not rotated on same plane of rotation easily, cause operation unstable; 3, coat brake gear and wear and tear easily, service life is short, and is dangerous; 4 aluminium, steel ring outside after being subjected to coat brake gets rusty easily and coats the brake meeting and can stay the trace of stopping on wheel, causes wheel not attractive in appearance.
Summary of the invention
The purpose of this utility model provides that a kind of light weight, wheel are attractive in appearance, long service life, the distortion that is difficult for being distorted, be difficult for reversing, supporting installation rises by brake apparatus, the small foldable bicycle of stopping easy to wear, not safe in utilization rises.
The purpose of this utility model is achieved in that
The small foldable bicycle, include vehicle frame, vertical rod top at frame-front fork is provided with handlebar, the vertical rod top of vehicle frame back vent is provided with saddle, on frame-front fork and back vent, be provided with wheel, be provided with drive sprocket in the junction of the back vent of vehicle frame and vehicle frame and be installed in pedal on the drive sprocket, before described, rear wheel comprises main shaft, inner ring, the wheel bar of outer ring and support inner ring and outer ring, on inner ring, be provided with the circular cavity that the brake apparatus that rises can be installed, in circular cavity, be provided with the brake apparatus that rises, a side of rear wheel inner ring be provided with by transmission device and drive sprocket bonded assembly driven sprocket, described inner ring, outer ring and wheel bar are integrated with aluminium.
Junction with front fork and back vent opening on the above-mentioned main shaft is provided with bearing.
Above-mentioned transmission device is chain drive or gear drive.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model wheel is made with aluminum, light weight, and inner ring, outer ring and the wheel bar of aluminium wheel are one-body molded, and the distortion that is difficult for being distorted can not influence the normal use of bicycle.
2, the utility model is provided with the brake apparatus that rises on the cavity of aluminium wheel inner ring, is difficult for getting rusty, and is not easy to wear, long service life, safety.
3, the utility model brake apparatus that rises is arranged on the cavity of inner ring, can not make braking mark stay on the wheel wheel overall appearance after the brake.
