[0002] Bicycle pads (that is, brake pads) play a vital role in the braking process. The shear strength between the friction material on the pads and the steel back directly affects the safety and service life of the bicycle. If the bicycle brakes The adhesive connection between the friction material of the sheet and the steel back is not firm, which may easily cause driving safety, so the first consideration is the shear strength. The so-called shear strength refers to the ability of the material to withstand shear force, and refers to the relationship between the external force and the axis of the material. Vertical, and the strength limit when shearing the material; At present, in order to overcome the above defects, symmetrical connecting columns are arranged on both sides of the brake pads. Although the connection is firm, it is known through experiments that the shearing strength is difficult control, has not met the required standard

Abstract

The invention discloses a bicycle brake pad, which is composed of a steel sheet (1) and a friction sheet (2), the steel sheet (1) has an inverted U-shaped structure, and the steel sheet (1) is provided with a reinforcing device, the reinforcing device is at least four bosses (3), and the bosses (3) are symmetrically arranged, so that the area where the bosses are inserted into the friction plate is large, and the distribution of the bosses is uniform. From a mechanical point of view, the angle Whether the setting is vertical or horizontal, the shear force of the brake pads is increased, and the shear strength of the brake pads is enhanced; the thickness of the high-temperature glue is controlled between 0.03 and 0.15mm during the gluing process, which increases the bonding strength. The friction plate (2) is composed of a friction material and a binder, and the friction material is a metal-less material, which makes the friction layer and the steel plate layer more adhesive and tough, thereby further increasing the shear strength of the brake pad, so that The glue joint can bear the maximum load of the parallel glue joint surface on the unit area.
