Summary of the invention
It is a kind of on the basis that does not change former clutch operation and brake control mechanism that the purpose of this utility model provides, can be by the crank motion of control cylinder and automatically reseting of retracing spring, make the action of flexible axle backguy control clutch and drg, compact conformation, rational fire extinguishing tanker power-transfer clutch and brake automatic control device.
The utility model is that the technical scheme that achieves the above object is: a kind of fire extinguishing tanker power-transfer clutch and brake automatic control device, it is characterized in that: comprise the flexible axle backguy, control cylinder, support, retracing spring and one control air valve, described control cylinder is rack-mount, one control air valve is installed on the control cylinder and with the air cavity of control cylinder and communicates, have exhaust shutter and intake-air throttle valve on the one control air valve, the both sides of the outer tube of flexible axle backguy are separately fixed on connecting panel and the support, and core one end of flexible axle backguy is connected with connecting panel, the other end of core passes support and is connected with the rod end of control cylinder, and the retracing spring that is sleeved on the flexible axle backguy one side line core withstands on respectively on support and the piston rod end face.
Wherein: core one end of described flexible axle backguy is fixed with forked element, and forked element is connected with a side of connecting panel by bearing pin.
Described support inboard is fixed with the outer spring seat, and the piston rod end of control cylinder is equipped with the inner spring seat, and its two ends of retracing spring that are enclosed within on the core withstand on respectively on outer spring seat and the inner spring seat.
The utility model is on the basis that does not change former clutch operation and brake control mechanism, flexible axle backguy and control cylinder have been increased, because the core two ends of flexible axle backguy are connected with the piston rod of connecting panel and control cylinder respectively, by flexible axle backguy control connecting panel is rotated with returning wheel shaft, by connecting panel the piston rod of carrying out cylinder is controlled, thereby make the braking of throw-out-of clutch or drg, reach the purpose of automatic guidance power-transfer clutch and drg action.The utility model only increase a control cylinder and with control cylinder bonded assembly one control air valve and flexible axle backguy, can realize that the automatic guidance clutch is handled and brake is handled, compact conformation, reasonable in design, be easily installed under the fire extinguishing tanker operator's saddle in the small space, and not influencing the function of original M/C power-transfer clutch and drg, cost is low, is convenient to existing fire-fighting vehicle is carried out the automatically controlled repacking.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: the 1-axis of revolution, the 2-connecting panel, 3-carries out cylinder, the 4-bearing pin, 5-forked element, 6-stretcher, the 7-adapter plate, the backguy of 8-flexible axle, 9-one control air valve, the 9-1-exhaust shutter, 9-2-intake-air throttle valve, 10-control cylinder, 11-inner spring seat, the 12-retracing spring, 13-outer spring seat, 14-support.
