Automobile guy cable, automobile brake and automobile

Abstract

The invention discloses an automobile guy cable, an automobile brake and an automobile. The automobile guy cable comprises a spring assembly and an outer sheath sleeving the outer wall of the spring assembly, wherein the spring assembly comprises one or more round steel wire springs and one or more flat steel wire springs; the spring rings of the round steel wire springs are clamped between adjacent spring rings of the flat steel wire springs. The springs of the automobile guy cable provided by the invention comprise the round steel wire springs and the flat steel wire springs, on one hand, when the springs of the guy cable receive bending force, the round steel wire springs do not generate a cutting action on the outer sheath of the guy cable, and on the other hand, when the flat steel wire springs receive bending force, the spring rings of the round steel wire springs can be squeezed outwards to support the outer sheath, so that the cutting action of a flat steel wire on the outer sheath is reduced; therefore, the round steel wire springs reduce the cutting action of the flat steel wire springs on the outer sheath from two aspects.

Description

technical field [0001] The invention relates to automobile technology, in particular to an automobile cable, an automobile braking device and an automobile. Background technique [0002] The gas pedal, driving brake system and parking brake system of the car are generally equipped with cables. figure 1 It is a structural schematic diagram of the parking brake system in the prior art, such as figure 1 As shown, the parking brake system includes a parking handle 1A, a front cable 2A connected to the parking handle 1A, and a left cable 3A and a right cable 4A connected to the front cable 2A. When parking, the driver operates the The parking handle 1A drives the front cable 2A to move, and the front cable 2A drives the left cable 3A and the right cable 4A to move, and the left cable 3A and the right cable 4A drive the parking brake to realize parking. [0003] figure 2 It is the sectional view of the automobile cable in the prior art, such as figure 2 As shown, the cable i...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the prior art is that there must be a curved part of the cable when it is arranged on the car. When the cable is subjected to a parking force, the outer sheath 5A of the curved part of the cable will be pressed by the edge of the flat steel wire spring 6A. The cutting action of the part, which causes the outer sheath 5A to crack easily, and the reliability is poor
