The invention discloses a vehicle wire harness assembly based on wheel speed sensing. The vehicle wire harness assembly comprises a signal wire body. The two ends of the signal line body are electrically connected with a wheel speed sensor and a matching interface respectively. The outer side of the signal line body is coated with a silica gel isolation layer, and a first cavity is formed between the silica gel isolation layer and the signal line body; the outer side of the silica gel isolating layer is coated with an outer rubber layer; isolation ridges are uniformly distributed on the outer wall of the silica gel isolation layer in the circumferential direction, and the space formed between the silica gel isolation layer and the outer rubber layer is divided into a plurality of second cavities by the isolation ridges; the second chamber is communicated with the first chamber; an electric heating wire spirally wound on the outer wall of the signal line body is further arranged in the first cavity, and the first cavity and the second cavity are both filled with heat conduction liquid; a temperature sensor is arranged on the matching interface; by arranging the temperature sensor, the electric heating wire and the heat conduction liquid, the outer rubber layer is heated, the situation that the temperature of the wire harness is too low, and consequently the wire harness is broken is prevented, and the structural reliability is higher.

    本发明公开了一种基于轮速传感的车辆线束总成,包括信号线本体;信号线本体的两端分别电性连接有轮速传感器和配合接口;信号线本体的外侧包覆有硅胶隔离层,硅胶隔离层与信号线本体之间形成有第一腔室;硅胶隔离层的外侧包覆有外橡胶层;硅胶隔离层的外壁沿周向均布有隔离楞,隔离楞将硅胶隔离层与外橡胶层之间形成的空间分隔有多个第二腔室;第二腔室与第一腔室连通;第一腔室内还设有螺旋缠绕在信号线本体外壁上的电热丝,第一腔室和第二腔室内均填充有导热液;配合接口上设有温度传感器;本发明通过设置温度传感器、电热丝和导热液,对外橡胶层进行加热,防止线束因温度过低而造成线束断裂发生,结构可靠性更高。
