Embodiment
[0014] When working, the kinetic energy of the engine is delivered to the hydraulic pump drive shaft 8 by driving the V pulley 9, and then transmitted to the hydraulic pump 4 by the spline sleeve 5. The transmitted mechanical energy is converted into hydraulic energy by the hydraulic pump 4 . The hydraulic energy is transmitted to the hydraulic motor 14 through the oil pipe. The hydraulic motor 14 converts hydraulic energy into mechanical energy and outputs it to the gearbox 12 with a clutch device, thereby driving the movement of the vehicle.
[0015] The oil in the hydraulic oil tank enters the charge pump of the hydraulic pump 4 through the oil pipe, and the oil replenishment pump supplies oil to the hydraulic system, and flows back to the hydraulic oil tank 2 through the oil drain port of the hydraulic motor 14 through the oil pipe through the hydraulic oil cooler 16 . Realize the functions of replenishing oil and heat dissipation of the hydraulic oil tank 2 of the device...
