A motorcycle position air intake temperature pressure sensor

Abstract

The invention discloses a motorcycle position air inlet temperature and pressure sensor which comprises a bottom cylinder.The left side and the right side of the top end of the bottom cylinder are provided with a pressure sensing cylinder and a temperature sensing cylinder respectively.A pressure chip is arranged at the top end of a top protruding block.An ejector block is connected with the top protruding block through a first top pressing spring.An elastic protrusion is arranged in the center of the bottom end of a buckle plate.A top disc is arranged inside the temperature sensing cylinder and connected with the temperature sensing cylinder through a second top pressing spring.According to the motorcycle position air inlet temperature and pressure sensor, due to the cooperation of the ejector block, the elastic protrusion and the second top pressing spring, pressing-fit stabilizing is performed on the pressure chip through a sealing pressing ring; when the sealing pressing ring is abraded, the first top pressing spring ejects the ejector block to eject the sealing pressing ring, the joint of the sealing pressing ring and the pressure sensing chip is prevented from loosening, the pressure sensing precision is improved, a temperature sensing piece is fixed through the buckle plate, the top disc is ejected by the second top pressing spring so that a hot sheet resistor is attached to the elastic protrusion, and the sensing precision of a thermistor is improved.

Description

technical field [0001] The invention relates to the technical field of motorcycles, in particular to a motorcycle position air intake temperature and pressure sensor. Background technique [0002] The motorcycle air intake temperature and pressure sensor mainly detects the pressure and temperature of the air in the throttle valve assembly, and converts it into a voltage signal and transmits it to the ECU. This signal is the main basis for controlling the fuel injection volume. The traditional sensor is pressure-sensitive The chip is fixed by a gasket with a sealing ring. When the sealing ring wears out with use, the pressure-sensing chip will become loose, thereby reducing the pressure-sensing accuracy. The temperature is sensed through a thermistor, but in the traditional technology, a heat transfer tube is installed. Conduct the hot air to the thermistor, but in reality, when the air circulation is unstable, it will affect the sensing accuracy of the thermistor. Contents...
