[0002] In the construction of infrastructure such as road repair, bridge erection and wind power generation, materials such as pre-cast bridges and wind turbine blades are often needed on site. These materials are generally severely overweight and oversized. At the same time, large cranes, shield machines and other heavy engineering machinery operating on the construction site cannot be safely transported by ordinary vehicles and must be transferred to the site by relying on professional large piece transport vehicles. On the one hand, the construction site is generally located between mountains and ravines, and the large piece transport vehicle needs to have good power performance to smoothly start and climb on unpaved roads. On the other hand, long-distance transportation must consider the fuel efficiency of the large piece transport vehicle.

[0003] In the field of large piece transport vehicles, heavy load starting, climbing and getting out of trouble have always plagued the development of the large piece transport industry. The ordinary dry clutch cannot withstand such a huge traction force. Therefore, the large piece transport vehicle is generally equipped with a hydraulic element to transmit engine torque to the transmission through hydraulic principle to achieve flexible starting. However, the efficiency of hydraulic transmission is far lower than that of mechanical transmission. In order to reduce fuel consumption, the large piece transport vehicle also needs to switch to mechanical transmission during normal driving after starting.

[0004] Currently, in order to realize the switching between hydraulic transmission and mechanical transmission, a wet locking clutch needs to be arranged inside the hydraulic element to control whether the hydraulic element participates in power transmission through the unlocking and locking of the locking clutch. However, the mechanical structure, oil circuit arrangement and locking oil pressure control of the wet locking clutch are relatively complex, and in addition, an ordinary dry clutch needs to be additionally configured between the hydraulic element and the transmission to realize the power interruption function during transmission shifting, and the overall structure is too complex and redundant.
