Problems solved by technology

[0003] 1. The power transmission of the parking brake assembly is composed of chains and round steel bars, and the appearance is not beautiful
[0004] 2. Due to the transmission of the parking brake combination chain and the round steel bar, there is an accumulated error in the gap between the connections, and the long-distance operation error from the operating mechanism to the brake is relatively large, which reduces the sensitivity of the operation
[0005] 3. Because the brake transmission is composed of chains and round steel bars, it is difficult to maintain and replace

Abstract

The invention discloses a track traffic brake cable assembly, and relates to track traffic equipment. The cable assembly comprises a wire cable, a protective sleeve and a mesh grid which are sequentially and tightly matched from the inside to outside; the end part of the cable assembly is provided with a connecting component; the protective sleeve comprises an inner core pipe, a straight steel wire pipe, an intertwined steel strip, a PE cladding and an outer protective layer which are tightly compounded from the inside to outside sequentially; and the connecting component is connected to the end part of the cable assembly in a mode of compression joint or clamping joint. The cable assembly can reduce accumulated error and improve brake sensitivity, has long service life and attractive appearance, and is convenient to maintain.

Description

technical field [0001] The invention relates to rail transit equipment, in particular to a cable assembly used for rail transit braking. Background technique [0002] The rail transit brake cable assembly is used to transmit force to the parking brake when the rail train stops, and is an indispensable connecting part when the train brakes. The transmission of the braking force during the braking of existing rail trains is connected with ordinary round steel bars and chains, which mainly has the following deficiencies: [0003] 1. The power transmission of the parking brake assembly is composed of chains and round steel bars, and the appearance is not beautiful. [0004] 2. Due to the transmission of the parking brake combination chain and the round steel bar, the accumulated error occurs in the gap between the connections, and the long-distance operation error from the control mechanism to the brake is relatively large, which reduces the sensitivity of the operation. [00...
