Abstract
The utility model provides a braking device for a bicycle, and is provided with a braking hub and a driving disk which are fixed to the hub, and a friction plate is arranged between the driving disk and the braking hub; besides, a braking shaft sleeve arranged on the braking device is installed on a wheel shaft, and the braking shaft sleeve is fixed by a nut arranged outside the braking shaft sleeve and screw threads on the wheel shaft. The driving disk is sheathed on the outer side of the braking shaft sleeve, trapezoidal screw threads which are mutually matched are arranged between the driving disk and the braking shaft sleeve, and at least three pieces of swelling compacting blocks are arranged on the outer margin of the driving disk. The friction plate is fixed to the outer surface of the swelling compacting blocks, the outer surface matches with the braking hub, and a conical surface can be adopted on the matching surface between the driving disk and the braking hub. The utility model has flexible and reliable braking and big force moment, with convenient application and maintenance.
Description
Technical field
This reality is newly with novel a kind of brake equipment, the particularly a kind of machine mechanical bicycle brake equipment of relating to.
Background technology
Bicycle is the most universal vehicle the most easily in our daily life, and whether the record of its brake is lived and not only be related to safety problem, also affects all many-sides such as mood, work of people.In the prior art, modal bicycle brake system is the brake mode that drive wheel adopts outsourcing to stop, this brake wants the new car initial stage comparatively flexible, but after period of service is long slightly, the fixing metal sheet of its strap of the brake deforms, can not and brake hubs between keep good concentricity, make to have brake in the cruising, increase worry.And when needs brake,, causing braking ineffective because of the contact surface between the strap of the brake and the brake hubs is little, and bad repairing allows people's headache, no anti-, seriously influences people's safety and quality of life.
Summary of the invention
The technical problems to be solved in the utility model is the pin the deficiencies in the prior art, has proposed a kind of bicycle brake system of the sincere flexibility and reliability of stopping.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of bicycle brake system, be characterized in: it is provided with and fixing braking hub, the driving disk of wheel hub, between driving disk and the braking hub friction lining is housed, it also is provided with a braking sleeve, described braking sleeve is contained on the wheel shaft, braking sleeve by being located at its outer end nut and the screw thread on the wheel shaft fix, described driving disk is sleeved on outside the braking sleeve, is provided with the Acme thread of working in coordination between driving disk and the braking sleeve.
The technical problems to be solved in the utility model can also come to realize that further the Acme thread between driving disk and the braking sleeve is the left-handed Acme thread of double end by the following technical programs.
The technical problems to be solved in the utility model can also come by the following technical programs to realize that further described driving disk outer rim is provided with at least three tightening pieces that described friction lining is fixed on the outside face that tightening piece cooperates with the braking hub.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that the fitting surface between described driving disk and the braking hub adopts cone match, and described friction lining is fixed on the conical surface of driving disk.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, it between described driving disk and the braking sleeve free-running fit, also be provided with slip cap in the back of driving disk and be contained in actuating sleeve on the braking sleeve, be provided with the bidirectional screw drive surface between actuating sleeve and the driving disk.
The utility model is provided with and fixing braking hub, the driving disk of wheel hub, between driving disk and the braking hub friction lining is housed, and driving disk is realized driving by left-handed Acme thread of double end or bidirectional screw drive surface.Compared with prior art, its sincere flexibility and reliability of stopping, braking moment is big, uses easy to maintenance.
