The purpose of this utility model reaches like this, a kind of aircraft deicing vehicle travel controls mechanism, this mechanism includes a chassis transmission shaft, characteristics are: described chassis transmission shaft is before the disconnection of nearly midway location place is divided into, rear propeller shaft 5,10, be connected with one and be controlled by HM Hydraulic Motor 7 and be placed in walking power takeoff 9 on the automotive frame disconnecting the position, this walking power takeoff 9 comprises one in order to before inciting somebody to action, rear propeller shaft 5, the normally closed power-transfer clutch 8 of throwing off between 10 or connecting and one is in order to the normally open clutch 11 that cuts off or 7 pairs of rear propeller shafts of closed HM Hydraulic Motor 10 are controlled, the front end of front propeller shaft 5 is connected on the main power takeoff 2 that is arranged on the automobile cab rear portion, main power takeoff 2 is connected with automobile gearbox, and, this main power takeoff 2 comprises one in order to the normally open clutch 12 with Hydraulic Pump 3 on-offs, this normally open clutch 12 by hydraulic tubing respectively with automatically controlled gas circuit change-over valve 6 and normally closed, normally open clutch 8,11 link, and the rear end of rear propeller shaft 10 is connected with automobile drive axle.
The utility model aircraft deicing vehicle travel controls mechanism, described normally closed power-transfer clutch 8 and normally closed power-transfer clutch 11 lay respectively in the walking power taking 9, normally closed power-transfer clutch 8 is connected with automatically controlled gas circuit change-over valve 6 gas circuits, and also be in transmission connection with forward and backward transmission shaft 5,10, normally open clutch 11 is connected with automatically controlled gas circuit change-over valve 6 gas circuits, and is in transmission connection with HM Hydraulic Motor 7, rear propeller shaft 10 respectively.
The utility model aircraft deicing vehicle travel controls mechanism, described normally open clutch 12 is connected with automatically controlled gas circuit change-over valve 6 gas circuits, and also is in transmission connection with Hydraulic Pump 3, front propeller shaft 5.
The utility model is owing to adopted said structure, and the advantage that possesses is: be under deicing, the defrosting mode of operation when removing ice machine, traveling gear can be realized low-speed running, makes the gait of march of automobile be in the degree less than 3Km/h; Need not to adopt two driving engines to control respectively, so mode is unicity control.
Accompanying drawing and drawing explanation
Fig. 1 is the structural representation of the utility model aircraft deicing vehicle travel controls mechanism.
Fig. 2 is the schematic diagram of the utility model aircraft deicing vehicle travel controls mechanism.
The specific embodiment
Please refer to Fig. 1 and in conjunction with Fig. 2, the utility model aircraft deicing vehicle travel controls mechanism also comprises foot control change-over valve 1, Hydraulic Pump 3, air tank 4, automatically controlled gas circuit change-over valve 6, HM Hydraulic Motor 7, foot control change-over valve 1 is installed in the aircraft deicing vehicle operator's compartment, it comprises a flip-flop 13, this flip-flop 13 realizes that with the Hydraulic Pump 3 that is arranged at except that ice machine driving compartment rear portion hydraulic tubing is connected with the HM Hydraulic Motor 7 that is installed in the automotive frame middle part respectively, more particularly, Hydraulic Pump 3 is by hydraulic tubing and foot control change-over valve 1, HM Hydraulic Motor 7 is connected, be Hydraulic Pump 3 → foot control change-over valve 1 → HM Hydraulic Motor 7, to realize the fluid control of motor.Air tank 4 is located on the chassis except that ice machine, and automatically controlled gas circuit change-over valve 6 is arranged on the high pressure gas of air tank 4 and guides into respectively on the gas channels 14 of walking power takeoff 9 and main power takeoff 2.In Fig. 2, illustrated corresponding annexation with three kinds of different lines respectively, specifically: so that-------lines signal gas circuit connects; With---...---lines signal hydraulic tubing connects; So that---signal of------lines is in transmission connection.Walking power takeoff 9 described in the utility model and main power takeoff 2 adopt the model of being produced by Baoji, Shaanxi province city Qingchun Machine Tool Group Corp., Ltd. to be respectively walking power takeoff and the main power takeoff of QJC600, QSE600Z.
