Description

Double-side simultaneous mechanical disc brake structure

The invention relates to a bilateral simultaneous-moving mechanical disc brake structure, in particular to each of the two guide members of the two handles is pulled by the steel cable connected by the connecting block to move the two guide members so that Each of the plurality of beads is slidingly displaced in a deep groove or a shallow groove of the first plate body, so that the plurality of beads reach an axial depth difference, and axially push the left and right sides of the first plate body and the pressing element, respectively. Innovative structural designer who can make the disc clamped or loose the predetermined disc set in the center in order to achieve the effect of disc brake.

Press, the conventional bicycle rear wheels do not have the design of sleeves and disc brakes for variable speed transmission on the same side. The rear wheels are generally equipped with traditional rim brake calipers. Due to the rim brake caliper arms and brakes, The blocks are arranged on the left and right sides of the rear wheel, so that the volume of the folded bicycle can not be further reduced due to the blocking of the brake calipers and the brake block, and the distance between the front and rear wheels of the vehicle body cannot be further reduced. The disc brake device, but can not set the sleeve for variable speed transmission, resulting in the rear wheel has no variable speed function.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, which is really desired by consumers, is also the goal and direction for relevant industry players to strive for breakthroughs. In view of this, the inventor of the present case has designed the components of the present invention in detail after many years of design experience, and after practical and careful evaluation, he finally has a practical invention.

That is, the main purpose of the present invention is to provide a bilateral simultaneous-moving mechanical disc brake structure. The problem to be solved is that conventional rear wheel brake clamps are generally used for conventional rear wheels. Because the brake arms and brake blocks of the rim brake calipers are located on the left and right sides of the rear wheel, the volume of the folded bicycle is blocked by the brake calipers and the brake blocks, which makes the distance between the front and rear wheels of the car body impossible. Reduced, although the conventional bicycle uses a disc brake device on the rear wheel, but it cannot be equipped with a variable-speed transmission sleeve, which improves and breaks the problem of the non-speed-changing function of the rear wheel. The technical characteristics of the problem are mainly borrowed. It consists of a frame base, two disc brake units including a guide, a plurality of beads, a first disk body, a second disk body, a pressing element and a limit cover, and a connecting block; With this innovative and unique design, the present invention can relatively guide the first disc body, the second disc body, and the pressing element through the guide members on both sides of the two disc brake unit, so that the two guides Each of the handles of the rotating member is moved by the steel cable connected by the connecting block to move the two guide members, so that each of the plurality of beads is slidingly displaced in a deep groove or a shallow groove of the first disc body, Make the multiple beads reach the axial depth difference. Push against the first disc pressing and tightening, respectively, left and right side elements of the interlocking of the sheet in order to clamp or unclamp a predetermined set to the center of the disk, to achieve the effect according to the disc brake's.
