Problems solved by technology
However, for tidal flat operating vehicles, they have the characteristics of high sealing requirements, many low-speed and high-torque working conditions, strong wading ability, and high environmental humidity. The current mechanical transmission and electric transmission cannot be suitable.
Especially when the beach is prone to subsidence and encounters high tide, the current mechanical transmission and electric transmission are difficult to avoid equipment flooding or electricity safety risks

Description
technical field [0001] The invention relates to a hydraulic drive system, in particular to a hydraulic drive system for tidal flat vehicles and its application. Background technique [0002] At present, vehicles are generally driven by internal combustion engines and electric motors, and the vehicles are driven by mechanical (hydraulic) transmission or direct drive by electric motors. Both technologies are relatively mature. However, for tidal flat operating vehicles, they have the characteristics of high sealing requirements, many low-speed and high-torque working conditions, strong wading ability, and high environmental humidity. The current mechanical transmission and electric transmission are not suitable. Especially when the beach is prone to subsidence and encounters high tide, the current mechanical transmission and electric transmission are difficult to avoid equipment flooding or electricity safety risks.
