On December 24, Hoshikoshi L Thor Hi · X successfully completed a tank of oil challenge 1300km ultra-long endurance, ran a tank of oil 1426.1km, the lowest fuel consumption of 100 kilometers of only 3.9L, set a new record for the lowest fuel consumption of the domestic hybrid big five flagship SUV, fully demonstrated its excellent fuel saving performance. The protagonist of this contest, Hoshigoku L Thor, Ishi The X oil-electric hybrid version also officially opened online pre-sale on the 25th.
What is the secret behind setting records? Geely Automobile opened the new Thor Power DHT Smart Micron Factory to the media and users for the first time, exploring the hardening road of the world's first 3-speed hybrid electric drive - DHT Pro through cloud release.
The new Raytheon Power DHT smart micron factory has invested billions of yuan, and the first phase plans to produce 300,000 transmissions per year, with an automation level of more than 70%, which is at the first-class level in the industry. It is reported that this factory adopts micron-level engraving precision manufacturing and micro-level management system to comprehensively benchmark European luxury car standards.
The world's leading vacuum quenching process, in the case of ensuring that the surface hardness reaches 60HRC, the core hardness is controlled at 33HRC, the depth fluctuation of the hardening layer can be controlled in the range of ±0.1mm, the internal toughness and external rigidity, and the deformation of the gear shape is less than 8 microns, which is 2 times better than the industry level.
The first in Asia to realize the "intelligent heating and pressing process" for large-diameter ring gear production. EMA automatic water-cooled press hardening machine, known as "wall breaker to prevent deformation", the deformation of the planetary ring gear shape after heat treatment is controlled within ±8 microns, and the honing processing process with a small margin after heating can be applied, breaking through the current situation of non-processing after heat of the ring gear in the industry.
In terms of management system, DHT Pro is the first hybrid electric drive of the Chinese brand to integrate a 60 bar high-pressure hydraulic system, and the valve body of the hydraulic system is assembled in a "separate chamber" of the micro factory. This chamber is a veritable IC-class dust-free assembly workshop. It is worth mentioning that the DHT micron factory also adopts the "0 error" intelligent selection system, which is finely grouped to achieve micron-level control of the entire assembly process and ensure the excellent quality of the whole life cycle.
Every new car off the production line must go through the strictest "graduation examination" and establish a lifetime file. Geely spent hundreds of millions of yuan to build two major test systems, EOL test and valve body test, which can carefully check all functions and NVH performance, with more than 100 steps in the detection link and up to 685 step-by-step parameters, achieving 100% automatic detection and achieving 100% qualified offline.
Out of sight, Geely is also pursuing excellence. As an important part of the 4.0 electrification system, Raytheon Power New Energy Test Center is the first world-class virtual simulation AI laboratory with full coverage, full simulation and full development, such as the NVH laboratory with only 8 decibels of bottom noise, which can simulate the powertrain extreme climatic environment simulation cabin within -40 °C to 60 °C, 5 meters to 5000 meters, and the high-performance laboratory that can clone the New North Circuit. It adopts the strict R&D and test standards of luxury and high-end brands to support the new energy power test of the world's top high-performance brands and supercar brands.
It is precisely with the high-precision manufacturing of "micron level" and the strict research and development test standards derived from luxury brands that DHT Pro has become a "hybrid artifact" and has fully surpassed Japanese brands in key technologies such as fuel saving, power, performance, and silence.
