Compared with prior art, the beneficial effects of the utility model are:
Hand-foot linked accelerator operating device of the present utility model has been cancelled spring box and mechanical linkage structure in the past, adopt two sections of flexible axles to connect facility and simple in structure is set, part is few, stability is high, convenient for installation and maintenance and cost is low, adopt manual accelerator and foot throttle soft axle transmission simultaneously, realized the integrated installation of system, dismounting maintenance does not affect other parts.
Accompanying drawing explanation
Figure 1 shows that the structural representation of hand-foot linked accelerator operating device of the present utility model;
Figure 2 shows that hand-foot linked structural scheme of mechanism of the present utility model;
Figure 3 shows that the A-A shown in Fig. 2 is to cross-sectional view.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, hand-foot linked accelerator operating device of the present utility model comprises manual accelerator 1, foot throttle 2, described manual accelerator comprises Manual operation mechanism 11 and manual governing turning handle 12, and described Manual operation mechanism is arranged on cab floor frame so that manual, described foot throttle 2 comprises the support 21 being fixedly installed on bottom plate of driving cab, can be rotatably set in the S. A. 23 on support, the stretcher 22 that is fixedly connected with or is integrally formed with described S. A., with described S. A. by the foot-propelled speed governing turning handle 24 that key 28 is connected or other modes are fixedly connected with, when described stretcher is depressed, described foot-propelled speed governing turning handle can occur synchronously to rotate counterclockwise thereupon, described manual governing turning handle 22 is rotatably connected with described S. A. 23, as connected by bearing or telescoping, wherein, the Manual operation mechanism of described manual governing turning handle and described manual accelerator is in transmission connection by pushing-pulling flexible shaft 10, described foot-propelled speed governing turning handle is connected with engine governed speed rocking-arm driving by the flexible axle with retracing spring and the retracing spring end of described flexible axle is connected with engine governed speed rocking arm, described foot-propelled speed governing turning handle is positioned at manual governing and rotates anti-clockwise the place ahead and when manual governing turning handle rotates counterclockwise, can drive foot-propelled speed governing turning handle synchronously to rotate.
Wherein, the retracing spring setting of foot-propelled speed governing turning handle can adopt various ways, as long as can make foot-propelled speed governing turning handle reset, the retracing spring end of the flexible axle with retracing spring described above can be connected on foot-propelled speed governing turning handle end, the extension spring that can pull foot-propelled speed governing turning handle to reset can also be set between described foot-propelled speed governing turning handle and the support on the left side, utilize extension spring to do retracing spring.
Specifically, described foot-propelled speed governing turning handle and the rotating shaft of manual governing turning handle are all S.
