Example 1
A transport vehicle for transporting wheel pairs of a railway rolling stock comprises a vehicle body 100, wherein the vehicle body 100 is provided with a motor driving system 1, and the motor driving system 1 is used for driving the vehicle body 100. The driving mechanism of the vehicle body 100 may be a wheel type driving mechanism or a crawler type driving mechanism, and the embodiment adopts the crawler type driving mechanism, so that the friction force is large, and the maintenance is convenient. The vehicle further comprises a hydraulic auxiliary system 2, wherein the hydraulic auxiliary system 2 is in transmission connection with the motor driving system 1 through a coupling mechanism 4, and the hydraulic auxiliary system 2 is used for assisting in driving the vehicle body 100 and recovering the kinetic energy of the vehicle body 100, namely the hydraulic motor 3 is used as a motor and a hydraulic pump in the embodiment. The vehicle body 100 is provided with a pushing device 20, and the pushing device 20 is used for pushing the wheel pair.
In particular, in connection with fig. 9, the hydraulic auxiliary system 2 includes a hydraulic motor 3, an output end of the electric motor driving system 1 is connected with an output end of the hydraulic motor 3 through a coupling mechanism 4, and the coupling mechanism 4 may be a rotational speed coupling mechanism or a torque coupling mechanism, and the embodiment is preferably a planetary gear coupling mechanism, so as to connect the electric motor driving system 1 and the hydraulic auxiliary system 2 with a wheel or a driving shaft of a transport vehicle for transporting a wheel pair of a railway locomotive vehicle in a transmission manner.
The hydraulic motor 3 is respectively connected with the high-pressure energy accumulator 6 and the low-pressure energy accumulator 7 through the three-position four-way electromagnetic valve 5, and it can be understood that two interfaces of the hydraulic motor 3 are respectively connected with one of two interfaces on the same side of the electromagnetic valve 5, and the interfaces of the high-pressure energy accumulator 6 and the low-pressure energy accumulator 7 are respectively connected with one of two interfaces on the other side of the electromagnetic valve 5. By reversing the solenoid valve 5, three connection states of the hydraulic motor 3 can be realized: firstly, hydraulic oil in the high-pressure energy accumulator 6 flows to the hydraulic motor 3 and then flows to the low-pressure energy accumulator 7; secondly, all interfaces are closed; thirdly, hydraulic oil of the low-pressure energy accumulator 7 flows to the hydraulic motor 3 and then flows to the high-pressure energy accumulator 6; namely, the electromagnetic valve 5 is used for controlling the flow direction of the hydraulic oil and the flow of the hydraulic oil, and the low-pressure accumulator 7 is used for supplying the hydraulic oil to the hydraulic auxiliary system 2 and stabilizing the pressure of the system.
