Waterproof ABS wheel speed sensor

Abstract

This utility model discloses a waterproof ABS wheel speed sensor, belonging to the field of wheel speed sensor technology. It solves the problem that in existing devices, only the ventilation holes on the side facing the vehicle's forward direction allow air to enter and contact the heat dissipation fins, resulting in only localized heat dissipation of the sensor body and poor heat dissipation effect. The sensor body includes a locking head at the top and a probe at the bottom; a waterproof heat dissipation assembly is installed on the outer side of the sensor body. Through the waterproof heat dissipation assembly, heat generated inside the sensor body can be conducted to the heat dissipation fins using a heat-conducting cylinder. During vehicle operation, external air can circulate through the gaps between the air intake, heat-conducting cylinder, and protective cover, as well as through the air outlet, to carry away the heat inside the heat dissipation fins, achieving uniform heat dissipation of the sensor body and improving the heat dissipation effect.
