Embodiment Construction

[0010] In the vehicle bearing seat temperature monitoring device of this embodiment, the temperature sensor mainly includes a dual-probe sensor assembly (1), a cable assembly (2), a tail nut assembly (3), and an electrical connector (4), among which, One end of the dual probe sensor assembly (1) is connected to the electrical connector (4) through the cable assembly (2), and the cable assembly (2) is connected to the electrical connector (4) through the tail nut assembly (3). When the test environment temperature changes When the resistance value of the platinum resistor (13) in the dual-probe sensor assembly (1) changes, the changed electrical signal is output to the console through the cable assembly (2) and the electrical connector (4), and the system will monitor the railway vehicle axle The immediate temperature of warm.

[0011] In the vehicle bearing seat temperature monitoring device of this embodiment, the single probe sensor assembly of the dual probe sensor assembly (1...

Abstract

Provided is a vehicle bearing pedestal temperature monitoring device. A temperature sensor mainly comprises a double-probe sensor module (1), a cable assembly (2), a tail nut assembly (3) and an electric connector (4), wherein one end of the double-probe sensor module (1) is connected with the electric connector (4) through the cable assembly (2); and the cable assembly (2) is connected with the electric connector (4) through the tail nut assembly (3). According to the vehicle bearing pedestal temperature monitoring device specially provided in the invention, the temperature sensor is simple in structure; a single probe is internally equipped with a platinum resistor (13), and thus monitoring precision is high; and the monitoring device is a direct-contact-type vehicle axle temperature detection device, is convenient to install, is arranged in a gear box of a bogie and enables axle temperature change due to gear rotation to be converted into electrical signals, which are output to a console.

Description

Technical field [0001] The invention relates to the design of a sensor, and in particular provides a temperature monitoring device for a bearing seat of a vehicle. Background technique [0002] At present, the existing temperature sensor has a complex structure, low accuracy, high manufacturing cost, and small application range. Summary of the invention [0003] The present invention particularly provides a vehicle bearing seat temperature monitoring device. The temperature sensor has a simple structure, a platinum resistance is installed in a single probe, and the monitoring accuracy is high. It is a direct contact type vehicle axle temperature detection device, which is convenient to install and is placed in In the gear box of the bogie, the axle temperature change caused by the gear rotation is converted into an electric signal and output to the console to monitor the real-time temperature of the axle temperature of the railway vehicle. The production cost is low, the productio...
