Embodiment Construction
[0052] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.
[0053] The background art above has shown that the tire pressure monitoring system has been widely used in large civil and military aircrafts. The tire pressure monitoring system monitors the internal air pressure of the tire, provides the actual tire pressure to the crew or maintenance personnel through the data bus and display, and can give an alarm to the low pressure and blowout of the tire. In daily maintenance, TPMS eliminates the manual measurement of tire pressure on the ground, reducing the workload of tire maintenance. Clearly, tire pressure monitoring systems are ...

The embodiment of the present invention discloses a hollow integrated tire pressure rotary actuator, which includes: an end cover, a pressure sensor, a cover plate with a central through hole, a rotary coupler, a wire pressing piece, a circuit board assembly, an electrical connector, a pressure Regulator, magnetic ring filter; circuit board assembly and pressure sensor are arranged on the bottom end surface of the end cover, and the cover plate installed with the pressure sensor and magnetic ring filter is installed on the other end surface of the end cover, and the assembled end cover and Its assembly components are a central hollow structure; the rotating body of the rotary coupler is fixed on the other end face of the cover plate, the primary cable is connected to the electrical connector at the end of the rotary coupler, and the secondary cables are respectively connected to the magnetic ring filter; completed The central hole of the assembled rotary coupler and the central through hole of the cover plate and the end cap are concentric holes. The embodiment of the present invention overcomes the disadvantage that the motor output shaft cannot be installed in the tire pressure monitoring module in the prior art, and at the same time improves the reliability of the communication between the tire pressure monitoring module and the tire pressure control module.
Description
technical field [0001] This application relates to but not limited to the technical field of wheel temperature and pressure monitoring and cooling, especially a hollow integrated tire pressure rotary actuator. Background technique [0002] On modern and advanced foreign aircraft, the Aircraft Tire Pressure Monitoring System (ATPMS), or simply the Tire Pressure Monitoring System (TPMS), has been widely used in large civil and military aircraft, for example, AIRBUS Among many models of , BOEING and DASSAULT, the latest A380 aircraft is also equipped with a tire pressure monitoring system. It is a technology that keeps aircraft safe. [0003] In the aircraft tire pressure real-time monitoring system, the in-wheel monitoring module is located on the wheel and rotates with the wheel at high speed. The working environment is harsh, and it needs to withstand harsh conditions such as high and low temperature, water vapor corrosion, salt spray corrosion, sand dust, strong vibration,...
