Description
Technical Field
[0001] The utility model relates to the technical field of vehicle engineering, in particular to an axle assembly with a thermal control system. Background Art
[0002] Insufficient heat dissipation in traditional axles Traditional axles lack an effective thermal control system. Under long-term or high-load use, axle components (such as gearboxes and bearings) are prone to overheating, affecting service life and performance. Excessive temperature will reduce the performance of the lubricant, increase friction and wear, and reduce transmission efficiency. Traditional axles without temperature monitoring function cannot understand their temperature status in real time. Lack of temperature monitoring makes it difficult to detect temperature abnormalities in time, which may lead to sudden failures. The inability to monitor temperature in real time makes it difficult to perform preventive maintenance, and can only rely on regular inspection and replacement of parts, increasing maintenance costs. Lack of displacement sensor Without displacement sensor, the displacement and vibration of various parts of the axle cannot be monitored in real time during vehicle driving, making it difficult to adjust and optimize vehicle performance in time. Without a displacement sensor, accurate data cannot be provided to support vehicle performance analysis and improvement. An existing split axle (publication number: CN216423978U) has the following disadvantages when in use:

[0005] 3.

[0006] The main purpose of the utility model is to provide an axle assembly with a thermal control system, which can effectively solve the problems in the background technology.
[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0008] A vehicle axle assembly with a thermal control system includes an axle shaft, a gear box is installed in the middle of the axle shaft, shaft end flanges are installed at both ends of the axle shaft, a motor is connected to the gear box, a brushless liquid cooling valve is connected to the motor, a liquid cooling pipe is installed on the brushless liquid cooling valve, the liquid cooling pipe surrounds the motor, a temperature monitoring sensor is installed on the motor, and a displacement sensor is installed on the shaft end flange. The gear box is fixedly connected to the middle of the axle shaft. The shaft end flanges are fixedly installed at both ends of the axle shaft. The motor is fixed to the gear box through a connecting component. The temperature monitoring sensor is electrically connected to the brushless liquid cooling valve. Two displacement sensors are provided.
[0009] Preferably, the gear box is fixedly connected to the middle position of the axle shaft.
[0010] Preferably, the shaft end flanges are fixedly mounted on both ends of the axle shaft.
[0011] Preferably, the motor is fixed to the gear box via a connecting component.
[0012] Preferably, the temperature monitoring sensor is electrically connected to the brushless liquid cooling valve.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. Brushless liquid cooling valve and liquid cooling pipe. The brushless liquid cooling valve controls the flow of coolant in the liquid cooling system through the motor. Brushless motors are more efficient and have a longer life than traditional motors. The liquid cooling pipe is installed around the motor, and the heat generated by the motor and gearbox is removed through the circulation of coolant in the pipe. After absorbing heat in the liquid cooling pipe, the coolant flows to the radiator, is cooled in the radiator, and then circulates back to the liquid cooling pipe. The liquid cooling system can more efficiently remove the heat generated by the motor and gearbox to prevent overheating. The liquid cooling pipe evenly surrounds the motor to ensure that the temperature of the entire motor surface is evenly distributed to avoid local overheating. The circulation of the coolant ensures a continuous cooling effect and can effectively dissipate heat even under high load or high temperature conditions.
[0015] 2. Temperature sensors installed on the surface of the motor and gearbox monitor the temperature of these key components in real time. The temperature sensor transmits real-time temperature data to the central control system (such as PLC). The control system analyzes it according to the set temperature threshold. When the temperature sensor detects that the temperature exceeds the set threshold, the control system can automatically increase the coolant flow or start the cooling fan to cool down.
[0016] 3. Displacement sensor The displacement sensor installed on the shaft end flange monitors the displacement and vibration of the axle shaft in real time. The displacement sensor transmits the monitored displacement and vibration data to the central control system for analysis. By analyzing the displacement data, the system can understand the dynamic performance of the axle under different working conditions and make corresponding adjustments. The displacement sensor provides real-time displacement and vibration data of the axle shaft to help identify dynamic performance problems. Through the analysis of displacement data, the vehicle's suspension and drive system can be optimized to improve driving stability and handling. When abnormal displacement and vibration are detected, timely response can be made to prevent potential mechanical failures and safety issues. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example
[0026] See also Figure 1-4 , the utility model provides a technical solution:
[0027] An axle assembly with a thermal control system includes an axle shaft 1, a gearbox 2 is installed in the middle of the axle shaft 1, shaft end flanges 3 are installed at both ends of the axle shaft 1, a motor 4 is connected to the gearbox 2, a brushless liquid cooling valve 5 is connected to the motor 4, a liquid cooling pipe 6 is installed on the brushless liquid cooling valve 5, the liquid cooling pipe 6 surrounds the motor 4, a temperature monitoring sensor 8 is installed on the motor 4, and a displacement sensor 7 is installed on the shaft end flange 3.

Two displacement sensors 7 are provided.
[0028]
[0029] It can be seen from the comparison data in the above table that the brushless liquid cooling valve and liquid cooling pipe of the utility model are compared with the traditional axle. The brushless liquid cooling valve controls the flow of coolant in the liquid cooling system through the motor. Brushless motors are more efficient and have a longer life than traditional motors. The liquid cooling pipe is installed around the motor, and the heat generated by the motor and gearbox is taken away by the circulation of coolant in the pipe. After absorbing heat in the liquid cooling pipe, the coolant flows to the radiator, is cooled in the radiator, and then circulates back to the liquid cooling pipe. The liquid cooling system can more efficiently take away the heat generated by the motor and gearbox, prevent overheating, and improve the heat dissipation efficiency by 30%. The liquid cooling pipe evenly surrounds the motor to ensure that the temperature of the entire motor surface is evenly distributed to avoid local overheating. The circulation of the coolant ensures a continuous cooling effect and can effectively dissipate heat even in high load or high temperature environments. The temperature sensors installed on the surface of the motor and gearbox monitor the temperature of these key components in real time. The temperature sensor transmits real-time temperature data to the central control system (such as PLC). The control system analyzes according to the set temperature threshold. When the temperature sensor detects that the temperature exceeds the set threshold, the control system can automatically increase the coolant flow or start the cooling fan to cool down, reducing overheating failures by 40%. Displacement sensor The displacement sensor installed on the shaft end flange monitors the displacement and vibration of the axle shaft in real time. The displacement sensor transmits the monitored displacement and vibration data to the central control system for analysis. By analyzing the displacement data, the system can understand the dynamic performance of the axle under different working conditions and make corresponding adjustments. The displacement sensor provides real-time displacement and vibration data of the axle shaft to help identify dynamic performance problems. Through the analysis of displacement data, the suspension and drive system of the vehicle can be optimized to improve driving stability and handling. When abnormal displacement and vibration are detected, timely response can be made to prevent potential mechanical failures and safety issues. The temperature monitoring accuracy reaches 60%, and the displacement monitoring accuracy reaches 60%.
[0030] The displacement sensor described in the utility model uses the LVDT displacement sensor 4000 series produced by Honeywell. The LVDT displacement sensor has extremely high measurement accuracy and can provide accurate displacement and vibration data, which helps to monitor the dynamic performance of the axle shaft in real time. This series of sensors adopts a sturdy structural design, suitable for working in harsh environments, and can withstand high temperatures, vibrations and shocks. It is very suitable for application scenarios with complex mechanical environments such as axles. Honeywell LVDT sensors have excellent stability and repeatability, and will not drift significantly after long-term use, ensuring data consistency and reliability. The sensor is compact in size and easy to install in the limited space of the axle, and has a standardized interface, which can be easily integrated with existing control systems (such as PLC), simplifying the installation and maintenance process. The rapid response capability of Honeywell LVDT sensors can capture the displacement and vibration changes of the axle shaft in a timely manner, which helps to adjust and optimize the suspension and drive systems of the vehicle in real time, and improve driving stability and controllability.
