Reponses courtes
Quelle autorité ou quel corridor local compte pour ce type ?
Commencez par la lentille locale : homologation, licences et hubs — pas une checklist mondiale.
Is this a buying guide?
No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.
Are the scores official?
No. The six scores are relative editorial 0–100 marks across the 48 types on this site.
Where do the photos come from?
Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.
Why metric units?
Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.
How is this different from a wiki article?
Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.
Sur Camion, propulsion, structure, commande et sécurité partagent la même enveloppe d'exploitation.
Les jauges résument marge structurelle, maintenabilité et facteurs humains en score relatif.
Systèmes
Structure
Camion: Heat-treated steel rails carry bending; fifth wheel or hitch plate transmits trailer kingpin loads into the frame.
Propulsion
Camion: Inline-six diesel with turbo and engine brake provides grade holding; multi-speed transmission splits torque for heavy haul.
Énergie
Camion: Tractor-trailer ABS with rollover stability control modulates trailer relay valves independently.
Commande
Camion: ELD, dashcam, and weigh-station bypass integrate through fleet gateways and satellite links.
Interface
Camion: Rear impact guards and side kits reduce car intrusion in low-speed crashes.
Sécurité
Camion: Flatbed chains, tarps, and refrigerated trailer bulkheads must meet FMCSA-style securement rules.
Indicateurs relatifs
Points chauds
Camion: Fifth wheel lock
Camion: Incomplete kingpin lock or worn jaws risks trailer separation at highway speed.
Camion: Gladhand seals
Camion: Air leaks between tractor and trailer reduce braking on the rear axles.
Camion: Turbocharger shaft play
Camion: Oil consumption and lag precede catastrophic turbo failure under boost.
Camion: Leaf spring hangers
Camion: Cracked hangers alter axle alignment and tire wear patterns.
Camion: Trailer ABS module
Camion: Fault codes on the blue circuit leave trailer wheels unmodulated during panic stops.
Matériaux
Camion: Grade 8 kingpin & plate
Camion: Hardened steel interfaces distribute trailer vertical and longitudinal loads.
Camion: Ductile iron brake drums
Camion: Massive drums on drive axles absorb heat from descending grades.
Camion: Aramid brake linings
Camion: Heavy-duty friction material resists fade on mountainous freight routes.
Camion: Synthetic engine oil 15W-40
Camion: High TBN oil extends drain intervals under sustained high load.
