Problems solved by technology

In addition, since the diaphragm 30 is initially used to withstand the internal pressure, and the pressure is transmitted to the indicator 32 through the diaphragm 30, the elasticity of the diaphragm 30 itself will affect the response characteristics of the indicator 32.
[0011] Furthermore, when using a switch that conducts through the contact of the plates, d

Abstract

The invention discloses a fixed type tire intrinsic pressure informing device with simple structure and excellent reliability, responsiveness and durability and a tire rim and tire group adopting the device. The type tire intrinsic pressure informing device is composed of a main body installed on the tire rim and an indicator bearing the tire intrinsic pressure, the main body with transparency is installed inside a mounting hole different from the valve port of the tire rim, and the intrinsic pressure of the tire is informed through the changes of the contact area between the inner surface of the main body and the indicator of the elastomer.

Description

[0001] This application is a divisional application of the application dated December 19, 2002, the application number is 02158963.1, and the title of the invention is "Inner pressure reporting device for tires and rim and tire set using this device". technical field [0002] The invention relates to a device for detecting insufficient air pressure, optimum pressure or excess pressure of tires, and reporting the detection results to passengers. Background technique [0003] In the prior art, in order to avoid deterioration of the riding condition and damage to the tire due to the reduction of the internal pressure of the tire, and to ensure the safety of the occupant, a device for notifying the occupant of the decrease in the internal pressure of the tire has been adopted. [0004] The annunciating device installed on the front end of the existing valve part is a device that the passenger installs and confirms the internal pressure according to needs. When the internal pressu...
