Throughout Tesla’s third-quarter earnings name, Elon Musk famous that the corporate continues to make headway on its future autos. Musk famous that he had already authorized the manufacturing of the Mannequin Y prototype, whereas stating that the corporate continues to make progress on the next-generation Roadster and the Tesla Semi. Musk additionally reiterated his enthusiasm in regards to the Tesla pickup truck, which he admits is the car he’s most enthusiastic about.
Among the enhancements to the Tesla Semi seem to have been teased in one of many firm’s recently-published patent functions. The patent, which was revealed on October 18, 2018, and titled “Computerized Tire Inflation System with Through-Hub Air Feed,” outlined a system enabling Tesla’s autos to inflate or deflate their tires as obligatory. Whereas a number of autos immediately have already got Computerized Tire Inflation Techniques, Tesla’s patent utility notes that typical ATIS have a lot room for enchancment.
“These prior options had various shortcomings. With some prior artwork strategies, air was fed by way of hole drive axles to a becoming positioned on the top thereof. The becoming was then coupled to the air inlets of the tires. To couple the air into the hole drive axles, a rotatingly connected becoming coupled air from an air storage to the within of the hole axles. This becoming was topic to leakage of contaminants. These contaminants interfered with the operation of the ATIS and finally brought about the ATIS to fail.”

Tesla’s ATIS patent includes a system that options valves, a rotary air seal, and bearings, to keep away from contamination. With such a system in place, Tesla notes that the wheels of its autos would doubtless last more, and tires would require even much less upkeep.
“So as to overcome the shortcomings described above amongst different shortcomings, an Computerized Tire Inflation System (ATIS) to be used with a car in response to a primary described embodiment features a controller, valves managed by the controller, the valves having an air provide inlet, and a plurality of air retailers. Additional, the ATIS consists of, for no less than one drive axle having interior bearings and outer bearings, a channel fashioned in a spindle, first hosing coupling a valve of the valves managed by the controller to the channel fashioned within the spindle, a channel fashioned in a hub, a rotary air seal residing between the interior bearings and the outer bearings and coupling the channel fashioned within the spindle to the channel fashioned within the hub, and second hosing coupling the channel fashioned within the hub to no less than one wheel.
“Thus, as in comparison with the prior ATIS methods, the ATIS of the primary embodiment, considerably reduces contamination within the ATIS air stream. Discount in contamination extends the lifetime of the ATIS, extends spindle life, extends hub life, and extends serviced wheel/tire lives and extends upkeep intervals.”
Whereas the diagrams within the patent utility recommend that Tesla’s upcoming ATIS could be used for the Semi, the functions for the automated tire inflation system for the corporate’s different, upcoming autos are notable. Having the potential to routinely inflate tires relying on the terrain, in spite of everything, would enable Tesla to start out giving its autos some type of off-road functionality. Below-inflated tires are key to off-road driving, since they’re able to flexing extra, permitting autos to “crawl” over rocks and different sharp, irregular terrain. Below-inflated tires even have a wider contact path, permitting autos to achieve extra traction in terrain like deep sand or smooth snow.
For now, Tesla’s autos are optimized for metropolis and interstate driving, and whereas there are accounts of the Mannequin X being taken off-road (EV YouTuber Bjorn Nyland’s excessive driving take a look at periods come to thoughts), the corporate’s electrical vehicles are but to have options which are particularly geared in direction of off-road driving. With an ATIS system, Tesla’s upcoming autos such because the Tesla pickup truck, and even the corporate’s SUVs just like the Mannequin Y and a future iteration of the Mannequin X, might have the power to discover areas past paved roads. Such capabilities would doubtless be invaluable, contemplating that legendary autos just like the Ford F-150 and the Chevy Blazer established their legacies by proving themselves succesful in areas the place neither asphalt nor concrete is current.
