Description
The application is entitled：A kind of air brake bicycle, the applying date be：On 06 25th, 2016, Application No.：
201610469287.1 application for a patent for invention divisional application.
Technical field
The present invention relates to a kind of bicycle, more specifically, it is related to air brake bicycle.
Background technology
Bicycle, also known as bicycle or bicycle, are typically the small-sized ground vehicles of two wheels.After people rides car, trampled with foot
Plate is power, is the environmentally protective vehicles.The brake system of bicycle is also had nothing in common with each other, and common are parking brake, is also had
Kind is extremely winged bicycle, its rear axle is fixation so it can be stepped on to brake backward by foot.
Existing bicycle in use, needs to stop to the front wheels and rear wheels of bicycle respectively using when braking
Car, is carried out at the same time the direction that control handlebar is also needed to during brake, this than relatively hazardous occasion, is unfavorable for the peace of user at some
Entirely, while existing parking brake, since the abrasion of brake rubber block can cause wheel to produce deflection in brake, so that bicycle
Direction is difficult to control, and undesirable influence can be caused on user.
To solve the above-mentioned problems, the present invention proposes air brake bicycle.
The content of the invention
In view of the deficiencies of the prior art, the present invention intends to provide air brake bicycle, it can not have to
Hand and the function of realizing front and rear wheel brake at the same time, while have the advantages that the frictional force that brake produces wheel is uniform.
To achieve the above object, the present invention provides following technical solution：Air brake bicycle, including vehicle frame, it is described
Handle, front wheels and rear wheels are installed, the vehicle frame is additionally provided with mounting rod, and vehicle seat is connected with the mounting rod, described on vehicle frame
Front-wheel and the trailing wheel include being used for installing fixed wheel shaft, and the side of the wheel shaft of the front-wheel and the trailing wheel is connected with brake
Component, the brake assemblies include the annular fixed frame for being fixed on the front wheels and rear wheels, and the fixed frame is equipped with annular
Brake film trap；The brake assemblies further include the brake portion being fixedly connected with the wheel shaft, the brake portion and the fixation
Frame is rotated and is tightly connected, and the brake portion is equipped with the brake groove of annular, and the brake groove is fixed close to fixed frame one end to be connected
Elastic rubber is connected to, the elastic rubber is tightly connected with the brake groove, and some brakes are fixedly connected with the elastic rubber
Car piece, the run-out circular shape that brakes, is fixedly connected with slide bar, slide opening, institute is equipped with the brake groove on the brake block
State brake block and connection is slid in diametric(al) by the slide bar and the slide opening, the brake trough wall surface is equipped with connection
Pipe；Air pressurizer is equipped with the mounting rod, the Air pressurizer includes the piston cylinder being fixed in mounting rod, institute
State piston cylinder to connect with the communicating pipe, be equipped with piston in the piston cylinder, be connected with the piston convenient for users to passing through
Foot tramples the foot pedal of compressed air.
By using above-mentioned technical proposal, can be pressurizeed afterwards to the air in piston cylinder by foot-treadle,
Air after pressurization is by entering in brake groove communicating pipe, and the pressure then braked in groove increases, due in brake film trap
Pressure does not increase, therefore pressure is then produced to elastic rubber, therefore elastic rubber produces change there are a pressure difference between the two
Shape, elastic rubber, which deforms, can drive the movement of brake block, while brake block be connected by the sliding with slide opening therefore it can only be
Moved in diametric(al), when brake block is to brake groove bad student's pressure, the two rubs mutually, due to brake portion and the wheel of bicycle
Axis is fixedly connected, and the effect of brake is then generated to bicycle.Air compression plant catches up with that there is provided left card in installation at the same time
Groove, middle card slot and right card slot, are rotated by adjusting pedal in rotation slot, and pedal is slid with above-mentioned each card slot by trampling
Connection is so as to realize a variety of brake purposes, wherein producing braking effect to trailing wheel merely, with left card slot sliding connection
Card slot connection front and back wheel produces braking effect at the same time, with there is card slot sliding connection to produce braking effect to front-wheel merely.This is voluntarily
Car steps on generation compressed air by foot, and then drives the movement of brake block, braking effect is produced, since the pressure of pressure difference comes from
From all directions, it is thus uniform for the pressure of brake block, it is thus possible to produce uniform frictional force.
The present invention is further arranged to：Into negative pressure state in the brake groove.
By using above-mentioned technical proposal, the original state for the groove that brakes is arranged to negative pressure state so that when not braking,
Elastic rubber can produce certain deformation, and brake block is not contacted with brake groove at this time, is so set and is enabled to stopping
Che Shi, same brake operation can produce the pressure differential of bigger, and then produce the pressure of bigger, there is provided more preferable friction effect
And braking effect.
The present invention is further arranged to：The communicating pipe is hidden to be arranged in the vehicle frame.
By using above-mentioned technical proposal, by communicating pipe it is hidden be arranged in the vehicle frame of bicycle, can avoid riding
During influenced communicating pipe, while be conducive to the overall appearance of bicycle.
The present invention is further arranged to：The fixed frame is equipped with the sealing for being used for being connected with brake portion rotary seal
Comb tooth.
By using above-mentioned technical proposal, due to fixed frame and brake portion rotates and sealed connection, on fixed frame
Multiple sealing comb teeth are set, and repeatedly sealing can be carried out to it has good sealing effect.
The present invention is further arranged to：Hydraulic oil is filled with the piston cylinder.
By using above-mentioned technical proposal, using hydraulic oil as driving medium, the pressure of bigger can be produced to brake block
Power, has more preferable braking effect.
The present invention is further arranged to：The brake block trough wall surface is equipped with the intercommunicating pore being in communication with the outside.
By using above-mentioned technical proposal, prevent the gas of brake film trap increases pressure due to compression, so as to obtain more
Big pressure difference, obtains more preferable braking effect.
In conclusion the invention has the advantages that：The present invention is stepped on by foot and produces compressed air or compression hydraulic
Oil produces pressure and then realizes at the same time to front and rear wheel brake, at the same the invention have the advantages that frictional force it is uniform, using steady.
