A tire inflation apparatuses is provided for maintaining a predetermined inflation pressure of a pair of tires mounted on a dual wheel unit of a vehicle. The apparatus includes a first and a second pump unit that are connected to a housing that includes a mounting structure for engaging a complementary mounting structure of the dual wheel unit. The first and second pump include first and second pump rods configured to translate in response to rotation of the dual wheel unit. A gearset and an eccentric drive mechanism are arranged to reciprocate the first and second pump rods.

Described herein is an inflation/deflation device of the type comprising a portion provided with an intake orifice for taking in a gaseous fluid under pressure, and a portion provided firstly with an inflation/deflation orifice designed to communicate with the confinement capacity, and secondly with a discharge orifice opening out between the two portions; and a valve member control system for inflation/deflation operations per se. In accordance with the invention, one of the portions is provided with arrangements for receiving a washer, which arrangements are suitable for allowing said washer to deform elastically, under the effect of a pressure of a gaseous fluid discharging through the discharge orifice, so as to release face-on bearing by an annular protuberance provided on the other portion, and so as to generate a fluid discharge passage between said annular protuberance and said washer.

A system and method of controlling pressure of a tire. The method may include executing a low supply pressure operating mode when an available supply pressure of pressurized gas is less than a target tire pressure. The tire may be inflated with pressurized gas provided at the available supply pressure when an estimated tire pressure is not within a threshold amount of the available supply pressure.

A system is disclosed included but not limited to a wheel having a wheel pressure chamber; a tire having a tire pressure chamber, wherein the tire is mounted on the wheel; a tire pressure sensor inside of the tire pressure chamber for measuring a tire air pressure inside of the tire pressure chamber; a wheel outlet valve between the wheel pressure chamber and the tire pressure chamber; a processor that reads a measure of the pressure inside of the tire pressure chamber from the tire pressure sensor and controls the wheel outlet valve to allow gas from the wheel pressure chamber to flow into the tire pressure chamber to increase the pressure in the tire pressure chamber when the tire pressure is less than a reference tire pressure. A method is provided for using the system.

An air maintenance tire pump simulator that simulates the environment of an air maintenance tire system is provided. The simulator includes at least one pneumatic cylinder, a structure that forms a closed cavity, and a pneumatic conduit extending between and fluidly connecting the pneumatic cylinder and the closed cavity. A cam is operably connected to a motor, and is also operably connected to the pneumatic cylinder. Engagement of the motor actuates rotation of the cam, which in turn actuates operation of the pneumatic cylinder to increase a pressure in the closed cavity. A method of simulating an air maintenance tire system is also provided.

A tire inflation system having a spindle that has a spindle fastener hole and spindle passage through which a pressurized gas flows for inflating a tire. An adapter or a fastener tube may inhibit pressurized gas from flowing from the spindle passage into the spindle fastener hole.

An instant wireless detecting apparatus installed in a trailer which includes a detecting mechanism and a monitor. The detecting mechanism is provided for detecting a tire condition of each the plurality of tires on a bottom of a loading board. The detecting mechanism will generate an identification code corresponds to an identification code respectively and output a wireless signal to the monitor. The monitor is automatically matched with the detecting mechanism according to the identification code and the tire condition is to be determined according to the detecting signal of the detecting mechanism corresponding to the identification code. A prompted message is sent by the prompt component, such that the installation of tire pressure detecting component can be simplified and the time for the installation of the tire pressure detecting component cal also be reduced.

A vehicle lifting and parking aid system having sidewinder wheel units mounted on the axles between the brakes and the spindle of each wheel of a vehicle controlled from a control module located within the vehicle is disclosed. In the deployed position, each sidewinder unit is against the ground surface and lifts the vehicle approximately 0.5″ off the ground. Using joysticks on a control module located within the vehicle, the user is able to operate, i.e. direct, the sidewinders to the left or right at different variations in speed whereby the vehicle is moved to the left or right by way of a rotating gear train.
