Disclosed are a patch-type passive surface wave sensing device and an intelligent tire, wherein the patch-type passive acoustic waving sensing device comprises a surface acoustic wave sensor (101) and at least comprises a first rubber sheet (201) and a second rubber sheet (202), the cross section of each of the first rubber sheet (201) and the second rubber sheet (202) is larger than that of the surface acoustic wave sensor (101), the bottom part of the surface acoustic wave sensor (101) is located on the upper surface of the first rubber sheet (201), a first central hole (204) allowing the surface acoustic wave sensor to penetrate therethrough is formed in the centre of the second rubber sheet (202), the surface acoustic wave sensor (101) penetrates the first central hole (204), the second rubber sheet (202) is fixedly connected to the upper surface of the first rubber sheet (201), the surface acoustic wave sensor (101) comprises pins (102) arranged at the bottom thereof, free ends of the pins (102) are connected to an antenna (103), and the antenna (103) and some of pins (102) are buried in the first rubber sheet (201). The intelligent tire comprises the patch-type passive surface acoustic wave sensing device which is fixed onto the inner wall of the tire. The patch-type passive surface acoustic wave sensing device requires no power supply , has the advantages of a small size and low weight, and has certain abilities of high temperature and high pressure resistance.
摘要:
A wireless sensor for a wheel end assembly of a heavy-duty vehicle is provided. The wheel end assembly includes a wheel hub and a hub cap mounted on the wheel hub. The sensor includes mounting means disposed in the hub cap. Sensing means are mounted on the mounting means to sense at least one condition of the vehicle. A processor is mounted on the mounting means and is electrically connected to the sensing means to process data from the sensing means. Communication means are mounted on the mounting means and are electrically connected to the processor to communicate the processed data to a user. An electrical energy storage device is mounted on the mounting means and is electrically connected to the sensing means, the processor and the communication means, enabling the sensor to be independent from the vehicle power supply. The sensor also accommodates components of a tire inflation system.
摘要:
A high temperature warning system for a vehicle steer axle air pressure supply, a normally-closed valve in fluid communication with pressure supply, a heat sensitive control capable of opening the normally-closed valve upon a predetermined temperature, the heat sensitive control mounted adjacent to the wheel end assembly in a heat exchange relationship therewith, and a warning system connected to the air pressure supply for actuation upon opening of the normally-closed valve.
