Embodiment Construction
[0022] Such as Figure 1-2 The shown auxiliary power system cabin door synchronous opening and closing control device includes a front door drive assembly and a rear door drive assembly. One end of 5 is hinged with the output end of the driving mechanism. The front door drive assembly and the rear door drive assembly have the same structure. The front door drive assembly includes a first rotating shaft 7 and a second rotating shaft 8 that are rotatably installed on the base 6. The first rotating shaft 7 is connected to the second rotating shaft. The phases of the two rotating shafts 8 are vertical. The first rotating shaft 7 is fixed with the first swing arm 9 and the second swing arm 10. The second rotating shaft 8 is fixed with the third swing arm 12. The second swing arm 10 connects with the first connecting rod 11 through the first connecting rod 11. The three swing arms 12 are hinged, and the rotation of the second rotating shaft 8 is driven by the rotation of the first r...

The invention discloses a synchronous opening and closing control device for hatch doors of an auxiliary power system, which comprises a front door drive assembly and a rear door drive assembly connected via a synchronous link, one end of the synchronous link is hinged to the output end of a drive mechanism, and the drive mechanism includes a valve group , oil tank, self-locking hydraulic cylinder and hydraulic pump controlled by motor, the valve group includes first check valve, second check valve, hydraulic control check valve, safety valve and shuttle valve, the tail of self-locking hydraulic cylinder The oil port is connected to one end of the hydraulic pump and one end of the hydraulic control check valve. The first oil port of the self-locking hydraulic cylinder is connected to the other end of the hydraulic pump and one end of the first check valve, and the other end of the hydraulic control check valve is connected to the first check valve. The other end of the one-way valve is connected to the fuel tank, the overflow port of the hydraulic pump is connected to the fuel tank through the second one-way valve, and the hydraulic control end of the hydraulic control check valve is connected to the tail oil port. The invention solves the problem of opening the hatch The problem of crawling phenomenon in the vehicle and the damage of the hatch due to the change of load ensures the synchronization.
Description
technical field [0001] The invention relates to a cabin door opening and closing device, in particular to a cabin door synchronous opening and closing device. Background technique [0002] The existing auxiliary power system (APS) hatch drive technology is divided into two types: 1. cylinder combined with mechanical synchronization and 2. rotary actuator combined with electrical synchronization. [0003] 1. Cylinder combined with mechanical synchronization; [0004] The compressed air in the aircraft environmental control system is used to push the cylinder out, and the linear motion of the cylinder is converted into rotary motion through a multi-link mechanism; it has the advantages of simple and reliable structure, light weight, easy maintenance, and no oil leakage pollution. The synchronous method can ensure that the two hatches are opened and closed synchronously, and only one actuator is needed, and the cost is low; however, there are the following problems during use:...
