The front tow hook is a core safety component for emergency rescue of commercial
vehicles, and its performance directly determines rescue reliability and road collision safety. To
address the common pain points of conventional commercial vehicle front tow hooks, such as
excessive rigidity, excessive front protrusion, structural redundancy, inconvenient installation and
use, and susceptibility to bolt fracture, as well as industry issues including that most mass-produced
products only meet the forward static load requirements of the national standard Commercial vehicles
Front towing devices (GB/T 28948－2012), are prone to failure under complex rescue conditions,
and exhibit poor vehicle-to-vehicle crash compatibility, this paper proposes two optimization
schemes: an integrated fixed tow hook and a retractable integrated tow hook. Through integrated base
design, load path optimization, innovative folding limit structures, and box-type protective design,
the structural dimensions and product weight are reduced while balancing towing strength and crash protection performance. Finite element simulation verification under multiple operating conditions
shows that the preferred integrated fixed tow hook achieves safety factors greater than 1 under three
typical operating conditions, meeting mandatory national standard requirements, and achieves a
35.3% weight reduction compared with the original structure. This scheme effectively addresses the
core defects of existing structures and can serve as a reference for the optimal design of similar
commercial vehicle safety components.
