Tyre pressure reporter and felly tyre set with the reporter

Abstract

The invention discloses a fixed tire internal pressure reporting device with simple structure and excellent reliability, responsiveness and durability, and a wheel rim and tire set using the device. The tire internal pressure notification device is composed of a main body mounted on the rim and an indicator that bears the tire internal pressure. The indicator is used to report the internal pressure of the tire, and a bearing is provided to separate the inner tube around the indicator from the rim. The pressure member notifies the internal pressure of the tire by deformation or movement of the above-mentioned indicator. While the above-mentioned rim and tire group has the internal pressure reporting device of the above-mentioned tire, a main body is also installed on the above-mentioned rim, and a valve main body for sealing air is installed on the above-mentioned main body.

Description

technical field [0001] 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 [0002] 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. [0003] 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 pressure is insufficient, the annunciating device can be removed to replenish air. In addition, in the case of a tubeless tire, a fixed reporting device can also be used by adding a diaphragm in the middle. [0004] For example, in the tire internal pressure...

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.

[0010] Furthermore, when using a switch that conducts through the contact of the plates, due to dirt and corrosion of the contacts, the conduction may not be ensured even if the contact is made, and in particular, the problem of aging over time cannot be avoided.

Therefore, there is a problem that even if the internal pressure of the tire is actually insufficient, the notification device cannot function, and eventually the tire etc. will be damaged.
