AI Technical Summary
Existing hydraulic systems in armored vehicles and motorboats are vulnerable to damage from impacts due to their proximity to the deck, leading to hydraulic oil leaks. This results in compromised normal operation and complex and costly maintenance.
The hydraulic device was repositioned below the hydraulic cylinder body, and the hydraulic nozzle was connected to the hydraulic cylinder body using precision welding. The oil port and connecting port structures were designed, and support springs and sealing rings were used to ensure sealing.
It effectively avoids hydraulic oil leakage, simplifies the maintenance process, improves the safety and reliability of the hydraulic system, and reduces maintenance costs.
