Wear-resistant brake line

Abstract

The present invention relates to a wear-resistant brake line which comprises an outer cladding layer (1), two lining tubes (2) side by side disposed in parallel and two metal wire groups (3), a brake line body (4) comprises an inner layer carbon fiber core line group (4.1 ) and an outer layer wear-resistant coating (4.2). The lining tubes can ensure two brake lines are equal in length so as to ensure that two brake line bodies are uniformly forced in braking; the brake line body is simple in molding, light in weight, chemical-resistant, good in weather resistance and low in cost of production; the wear-resistant brake line effectively increases the frictional force and the support force between the lining tubes and the cladding layer, the lining tubes and the cladding layer are less prone to relative sliding, and the used effect of the brake system can be ensured.

Description

technical field [0001] The invention relates to a wear-resistant brake line, which is used in a bicycle brake system. It belongs to the field of bicycle accessories. Background technique [0002] The bicycle brake system includes accessories such as brake handles, brake lines, and brake calipers. The brake system of the prior art is usually provided with a front and a rear brake line and two corresponding brake handles and two brake calipers. The brake line is prone to breakage after being used for a period of time, causing brake failure and high potential safety hazards. In order to solve the above technical problems, it is necessary to use a two-line brake system with two front brake lines and two rear brake lines. The two brake lines of this brake system The length of the two front brake cables needs to be the same to ensure that the two brake cable bodies are evenly stressed during braking. However, the two independent brake cable bodies cannot guarantee the same length...

[0002] The bicycle brake system includes accessories such as brake handles, brake lines, and brake calipers. The brake system of the prior art is usually provided with a front and a rear brake line and two corresponding brake handles and two brake calipers. The brake line is prone to breakage after being used for a period of time, causing brake failure and high potential safety hazards. In order to solve the above technical problems, it is necessary to use a two-line brake system with two front brake lines and two rear brake lines. The two brake lines of this brake system The length of the two front brake cables must be the same to ensure that the two brake cable bodies are evenly stressed during braking. However, the two independent brake cable bodies cannot guarantee the same length, and there are certain difficulties in assembly.

[0003] The existing brake line body is composed of an outer rubber hollow tube and an inner steel wire, its strength is not high enough, its chemical corrosion resistance is poor, its weather resistance is not good, and its production cost is relatively high

[0004] The friction and supporting force between the inner liner and the outer cladding of the existing brake line are not enough, and the inner liner and the outer sheath tend to slide relative to each other, which will cause the brake to not be tight and affect the use effect of the braking system
