Abstract
The invention belongs to the field of accessories of communication media and discloses a mechanical-type automatic bicycle safety speed limiting device which is composed of a box, a chain wheel, a transmission shaft, a steel ball, a thrust disc, a transmission disc, a pull rod, a pin shaft, a small spring, a big spring, a spring seat, a brake shoe and a bearing. The mechanical-type automatic bicycle safety speed limiting device has the advantages that when bicycle speed is overhigh, under joint action of chain transmission, centrifugal force and the springs, the brake shoe is enabled to move in a direction being close to the outer surface of a bicycle rim and to finally lean against the outer surface of the bicycle rim to form big friction force so as to decrease rotating speed of the bicycle rim, so that the objective of automatic speed reducing is achieved, and riding safety is realized.
Description
Technical field
The present invention relates to a kind of new bicycle accessory, specifically a kind of mechanical bicycle safety automation speed-limit device, belongs to bicycle accessory equipment field.
Background technology
As everyone knows, bicycle is the most basic vehicle of current China.But bicycle partial function shortcoming, can not give play to speed limit effect at present, is easy to cause danger in the situation that the speed of a motor vehicle is too fast, brings massive losses.Therefore, in the urgent need to a kind of bicycle speed-limit device, but there is no in the market such device.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of mechanical bicycle safety automation speed-limit device.
The present invention is achieved by the following technical solutions: a kind of mechanical bicycle safety automation speed-limit device, by casing, sprocket wheel, transmission shaft, steel ball, thrust disc, drive plate, pull bar, bearing pin, little spring, big spring, spring perch, brake rubber block, bearing composition, casing is fixed on vehicle frame, brake rubber block is arranged near rim outside face, be fixed on pull bar one end, sprocket wheel is fixed on transmission shaft, transmission shaft is arranged on casing by bearing, drive plate is fixed on transmission shaft, pivot shaft is fixed on casing, thrust disc empty set is on pivot shaft, and contact with little spring, little spring is fixed on spring perch, steel ball is put between drive plate and thrust disc, bearing pin is fixed on casing, pull bar is arranged on bearing pin, pull bar contacts with big spring, big spring is fixed on casing.
The usefulness of this invention is: in the time that bicycle is worked, along with the increase of speed, the speed of sprocket wheel constantly increases, by transmission shaft band nutating disk and steel ball rotation, because steel ball rotation produces centnifugal force, make thrust disc against the force of the spring to the direction motion near spring perch.When speed reaches a timing, thrust disc contacts with pull bar and pull bar is clockwise rotated around bearing pin, thereby brake rubber block is to the direction motion near rim outside face, and finally lean against on rim outside face, form larger friction force, reduce rim velocity of rotation, thereby reach the object of automatic retarding, play the effect of traffic safety.

Accompanying drawing 1 is structural representation of the present invention.
In figure, 1, casing, 2, sprocket wheel, 3, transmission shaft, 4, bearing, 5, drive plate, 6, steel ball, 7, thrust disc, 8, little spring, 9, spring perch, 10, big spring, 11, pull bar, 12, bearing pin, 13, brake rubber block.
Detailed description of the invention
As shown in the figure, a kind of mechanical bicycle safety automation speed-limit device, by casing 1, sprocket wheel 2, transmission shaft 3, steel ball 6, thrust disc 7, drive plate 5, pull bar 11, bearing pin 12, little spring 8, big spring 10, spring perch 9, brake rubber block 13, bearing 4 forms, casing 1 is fixed on vehicle frame, brake rubber block 13 is arranged near rim outside face, be fixed on pull bar 11 one end, sprocket wheel 2 is fixed on transmission shaft, transmission shaft 3 is arranged on casing 1 by bearing 4, drive plate 5 is fixed on transmission shaft 3, pivot shaft is fixed on casing 1, thrust disc 7 empty sets are on pivot shaft, and contact with little spring 8, little spring 8 is fixed on spring perch 9, steel ball 6 is put between drive plate 5 and thrust disc 7, bearing pin 12 is fixed on casing 1, pull bar 11 is arranged on bearing pin 12, pull bar 11 contacts with big spring 10, big spring 10 is fixed on casing 1.
When this device busy, casing 1 is fixed on vehicle frame, brake rubber block 13 be arranged near rim outside face and can do away from crank motion near rim surface, sprocket wheel 2 is connected with wheel disc by chain, when the speed of a motor vehicle is too fast, brake rubber block 13 compresses rim, makes its deceleration.
For the ordinary skill in the art, according to instruction of the present invention, in the situation that not departing from principle of the present invention and spirit, within change, amendment, replacement and the modification that embodiment is carried out still falls into protection scope of the present invention.
