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.
The specific embodiment
See shown in Figure 1, fire extinguishing tanker power-transfer clutch of the present utility model and brake automatic control device, comprise flexible axle backguy 8, control cylinder 10, support 14, retracing spring 12 and one control air valve 9, the utility model control cylinder 10 is installed in support 14 1 sides, one control air valve 9 is installed on the control cylinder 10 and with the air cavity of control cylinder 10 and communicates, have exhaust shutter 9-1 and intake-air throttle valve 9-2 on the one control air valve 9, can be by intake-air throttle valve 9-2 to regulate the speed that power-transfer clutch or drg are thrown off, and exhaust shutter 9-1 regulates the speed that power-transfer clutch or drg reset, the both sides of flexible axle backguy 8 outer tubes are separately fixed on the opposite side of adapter plate 7 and support 14, and adapter plate 7 is installed on the frame by fastener, can be screwed on connecting panel 2 and the support 14 by the retaining thread on the outer tube of flexible axle backguy 8, core one end of flexible axle backguy 8 is connected with connecting panel 2, these connecting panel 2 one sides are captiveed joint with axis of revolution 1, and stretcher 6 is also captiveed joint with axis of revolution 1, this stretcher 6 is clutch foot plate or brake pedal plate, and connecting panel 2 is connected with the piston rod of carrying out cylinder 3, carry out the piston rod action of cylinder 3 by the action band control of stretcher 6 or connecting panel 2, core one end of this flexible axle backguy 8 is fixed with forked element 5, forked element 5 is connected with a side of connecting panel 2 by bearing pin 4, the other end of core passes support 14 and is connected with the rod end of control cylinder 10, the piston rod indentation of control control cylinder 10, pulling flexible axle backguy 8, the retracing spring 12 that is sleeved on the flexible axle backguy 8 one side line cores withstands on respectively on support 14 and the piston rod end face, support 14 inboards are fixed with outer spring seat 13, the piston rod end of control cylinder 10 is equipped with inner spring seat 11, retracing spring 12 its two ends that are enclosed within on the core withstand on respectively on outer spring seat 13 and the inner spring seat 11, by retracing spring 12 core of flexible axle backguy 8 is withdrawn, do not influence manual handling.
