Abstract

The invention relates to a vehicle brake cable. The vehicle brake cable is characterized by comprising a steel stranded wire (1) in the center, wherein the middle of the steel stranded wire (1) is a middle core layer (1.1); four to eight steel strands (1.2) are arranged on the periphery of the middle core layer (1.1); the steel strands (1.2) are stranded on the surface of the middle core layer (1.1); a first protecting layer (2) sleeves the outside of the steel stranded wire (1); a plurality of strengthening straps (3) are wound on the outside of the first protecting layer (2) in the radial direction of the first protecting layer (2) and are high polymer fibers; a second protecting layer (4) further sleeves the outsides of the strengthening straps (3); and the first protecting layer (2) and the second protecting layer (4) are made of rubber. The center of the vehicle brake cable is the steel stranded wire, after the steel stranded wire is stranded by the steel strands, the strength of the steel stranded wire is higher than that of the original single-strand steel wire, the first protecting layer, the strengthening straps and the second protecting layer are successively arranged outside the steel stranded wire, metal wires can be prevented from being broken, and therefore, safety of a vehicle is improved.

Description

Vehicle brake line

Technical field

The present invention relates to a kind of vehicle brake line, for bicycle, electromobile, motorcycle, tricycle, belong to mechanical equipment technical field.

Background technology

The brake system of vehicle includes the accessories such as brake lever, brake cable, brake binder.Conventional vehicle brake line is single metal wire, and such tinsel strength is the highest, and brake cable easily ruptures in the case of by strength external force, thus have impact on the safety of vehicle.

Summary of the invention

In order to overcome above-mentioned deficiency, the invention provides one not easy fracture, the vehicle brake line that safety is high.

The object of the present invention is achieved like this:

A kind of vehicle brake line; it includes the steel strand wires in bosom; the centre of steel strand wires is intermediate core layer; this intermediate core layer is PP core, hemp core, yarn core or PU core; the periphery of described intermediate core layer is provided with four to eight steel strands; multiple steel strands are stranded in intermediate core layer surface; the outside of described steel strand wires is cased with the first protective layer; the outside of the first protective layer is radially wound with a plurality of reinforcing tape; described reinforcing tape is macromolecular fibre silk; the outside of described reinforcing tape is also cased with the second protective layer, the first protective layer and the second protective layer and is rubber and makes.

Vehicle brake line of the present invention has the advantages that

The center of this vehicle brake line is steel strand wires; steel strand wires by steel strand stranded after; higher compared with the intensity of original single steel wire; not easy fracture; the outside of steel strand wires is sequentially provided with the first protective layer, reinforcing tape and the second protective layer; it is possible to prevent wire breakage, thus improves the safety of vehicle.

Accompanying drawing explanation

Fig. 1 is the sectional view of the central steel twisted wire of vehicle brake line of the present invention.

Fig. 2 is the structural representation of vehicle brake line of the present invention.

Wherein: steel strand wires 1, intermediate core layer 1.1, steel strand the 1.2, first protective layer 2, reinforcing tape the 3, second protective layer 4.

Detailed description of the invention

Such as Fig. 1 and Fig. 2, the present invention relates to a kind of vehicle brake line, steel strand wires 1 including bosom, the centre of steel strand wires 1 is intermediate core layer 1.1, this intermediate core layer 1 is PP core, hemp core, yarn core, the synthetic materials such as PU core, or above-mentioned material is composited, the periphery of described intermediate core layer 1.1 is provided with four to eight steel strands 1.2, multiple steel strands 1.2 are stranded in intermediate core layer 1.1 surface, the outside of described steel strand wires 1 is cased with the first protective layer 2, the outside of the first protective layer 2 is radially wound with a plurality of reinforcing tape 3, described reinforcing tape 3 is macromolecular fibre silk, the outside of described reinforcing tape 3 is also cased with the second protective layer 4, first protective layer 2 and the second protective layer 4 are rubber and make.
