Detailed description of the invention
Fig. 1 is the utility model clutch control schematic diagram.
Each part numbers are as follows in figure: 1- engine flywheel, 2- clutch, 21- disengaging yoke, 3- transmission input shaft,
4- output shaft of gear-box, 5- dynamometer machine main shaft, 6- slave cylinder, 61 relay piston bars, 7- high-pressure oil pipe, 8- actuating cylinder, 81
Active piston bar, 9- cylinder, 91 pneumatic piston rods, 92- cylinder stroke switch, 10- hydraulic oil container, 11- air operated reversing valve.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, convenient for more clearly understanding that this is practical new
Type, but they do not constitute the utility model and limit.
As shown in Figure 1, a kind of hybrid power engine bench test clutch controller, including it is located at engine flywheel
Clutch 2 between 1 and transmission input shaft 3, clutch 2,2 one end of clutch is fixedly connected with transmission input shaft, another
End is abutted with engine flywheel, and transmission input shaft 3 is fixedly connected by output shaft of gear-box 4 with dynamometer machine main shaft 5, clutch
2 further include having disengaging yoke 21, its mechanism structure of above-mentioned clutch is existing mechanical friction clutch, manual on vehicle
Gearbox using when need to be stirred by pedal separation fork 21, and in engine rig test must pass through automatically control dress
It sets to control the separation and actuation of clutch 2 Yu engine flywheel 1.
Above-mentioned clutch controller further includes actuating cylinder 8 and slave cylinder 6, and slave cylinder 6 is fixed on engine examination
It tests on rack, slave cylinder 6 includes relay piston bar 61,61 one end of relay piston bar and hinged, the driven oil that separates fork 21
6 other end of cylinder is connected to by high-pressure oil pipe 7 with actuating cylinder 8, and 8 other end of actuating cylinder includes active piston bar 81, actively
Piston rod 81 is fixedly connected with the pneumatic piston rod 91 on cylinder 9, and 9 cylinder body of actuating cylinder is also connected with hydraulic oil container 10, cylinder 9
On be also connected with the air operated reversing valve 11 of controllable 91 moving direction of pneumatic piston rod.Pneumatic work can be limited by being additionally provided in cylinder 9
Fill in the cylinder stroke switch 92 of shift motion.Clutch 2 is controlled in this way, being combined by pneumatic control and hydraulic control mode
The long-range control to clutch 2 can be achieved in the combination of system, actuating cylinder 8 and slave cylinder 6, so that the control device of clutch 2
