Problems solved by technology

[0003] The prior art pads all include a fixed plate and a friction block, which have low strength and insufficient service life. The main reasons are the insufficient strength of the fixed plate and the low connection strength between the fixed plate and the friction block; the former is easy to cause plate necking. Deformation or cracks will increase the parallelism error between the friction block and the brake disc (drum), resulting in a decrease in the friction area; the latter is mainly due to the different materials of the fixed plate and the friction block, which need to be chemically bonded or mechanically connected to the fixed plate and friction block, but the chemical adhesive is easy to age, the bonding strength is insufficient, and the mechanical connection processing and assembly procedures are cumbersome

Embodiment Construction

[0020] In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and the best embodiments.

[0021] A high-strength pad of the present invention includes a fixed plate and a friction block 7 that are fixedly connected. The fixed plate includes a fixed plate body 5, a plate neck 2 extending from one end of the fixed plate body, and a fixed plate protruding perpendicular to the fixed plate body. The column 4, the fixing hole 3 on the plate neck and the positioning part 6 at the other end of the fixing plate body. The fixing column is provided with a coaxial embedding hole 41 which penetrates the fixing plate body, and the column end 42 of the fixing column is provided with a convex The plane of the boss and the fixed plate body forms an annular groove 43 on the fixed column, and the fixed column is also provided with a str...

Abstract

The invention discloses a high-strength lining including a fixing board and a friction block. The fixing board includes a fixing board body, a board neck, a fixing column, a fixing hole, and a positioning part, the fixing column is provided with an insert hole, the column end of the fixing column is provided with a boss to form a circular groove on the fixing column, the fixing column is provided with a bar-shaped groove along the axis, the friction block being formed by powder hot pressing is connected with the fixing board, the friction block is inserted into the insert hole, the circular groove, and the bar-shaped groove to form connection, and the edges of the two sides of the board neck form protruding reinforcing ribs through stamping forming. The friction block of the lining is inserted into the insert hole, the circular groove, and the bar-shaped groove through powder hot pressing to automatically form the non-detachable mechanical high-strength connection with the fixing column without the need for extra assembling; and the fixing board enhances the rigidity and strength of the geometric surface through the reinforcing ribs while the weight of itself is maintained, the board neck bending deformation or cracking during the braking can be overcome, and the lining is reliable in work and long in service life.

Description

technical field [0001] The invention relates to the technical field of bicycle brake pads, in particular to a high-strength pad. Background technique [0002] The brake pad is the most critical safety part in the bicycle braking system, and it plays a decisive role in the braking effect. The working principle of the brake is mainly from friction. The friction between the pad and the brake disc (drum) and the tire and the ground is used. Convert the kinetic energy of the vehicle into frictional heat energy to stop the bicycle. [0003] The prior art pads all include a fixed plate and a friction block, which have low strength and insufficient service life. The main reasons are the insufficient strength of the fixed plate and the low connection strength between the fixed plate and the friction block; the former easily leads to the occurrence of plate necks. Deformation or cracks will increase the parallelism error between the friction block and the brake disc (drum), resulting...
