Compared with prior art, the beneficial effects of the invention are as follows：
The hand-foot linked accelerator operating device of the present invention eliminates conventional spring box and mechanical linkage structure, using two
Section flexible axle connect setting is facilitated and simple in construction, and part is few, and stability is high, convenient for installation and maintenance and low cost, while using hand
Throttle and foot throttle soft axle transmission, realize the integrated installation of system, and dismounting maintenance does not influence other parts.
Brief description of the drawings
Fig. 1 show the structural representation of the hand-foot linked accelerator operating device of the present invention；
Fig. 2 show the hand-foot linked structural scheme of mechanism of the present invention；
Fig. 3 show the A-A profile structure diagram shown in Fig. 2.
Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
As Figure 1-3, hand-foot linked accelerator operating device of the invention includes hand throttle 1, foot throttle 2, described
Hand throttle includes Manual operation mechanism 11 and manual governing turning handle 12, and described Manual operation mechanism is arranged on cab floor frame
On in order to manual control；Described foot throttle 2 include be fixedly installed on bottom plate of driving cab support 21, can be rotatably set in branch
Rotary shaft 23 on frame, the pedal 22 for being fixedly connected or being integrally formed with described rotary shaft, pass through with described rotary shaft
The foot-propelled speed governing turning handle 24 that key 28 is connected or other modes are fixedly connected, when described pedal is depressed, described pin
Dynamic speed governing turning handle can occur therewith it is synchronous rotate counterclockwise, described manual governing turning handle 22 and described rotary shaft 23 are rotatable
Ground is connected, and such as is connected by bearing or bushing type, wherein, the manual behaviour of described manual governing turning handle and described hand throttle
Vertical mechanism is connected by pushing-pulling flexible shaft 10, and described foot-propelled speed governing turning handle passes through flexible axle and engine with back-moving spring
Speed governing rocking-arm driving is connected and the back-moving spring end of described flexible axle is connected with engine governed speed rocking arm, and described foot-propelled speed governing turns
Handle is located at manual governing and rotates anticlockwise front and can drive foot-propelled speed governing when manual governing turning handle is rotated counterclockwise
Turning handle synchronous axial system.
Wherein, the back-moving spring of foot-propelled speed governing turning handle sets and can taken various forms, as long as can make foot-propelled speed governing turning handle
Reset, the back-moving spring end of the flexible axle with back-moving spring described above can be connected on foot-propelled speed governing turning handle end, can be with
The extension spring that foot-propelled speed governing turning handle can be pulled to reset is set between described foot-propelled speed governing turning handle and the support on the left side, that is, utilizes drawing
