The clutch pedal control structure has the beneficial effects of simple structure, flexible operation, accurate control and capability of saving installation space.
Description
Technical field
The utility model relates to the trac. technical field, relates in particular to a kind of tractor clutch's pedal control structure.
Background technology
On trac. or heavy-duty vehicle, adopt power-transfer clutch to carry out transmission of power more.Traditional mechanical linkage power-transfer clutch, owing to by stretcher, driving clutch friction plate action by connecting rod mechanism, not only step on effort, and power-transfer clutch from, close moment, can cause driving engine and chassis to vibrate.At present, on some large tractores, adopted the electric control clutch system, namely by stretcher, send automatically controlled signal to central process unit, central process unit changes according to the position angle that stretcher provides, by optimization process, send actuating signal and carry out the control clutch action, realize the combination of power-transfer clutch fast speed or separate.And the pedal structure of original technology is heavier, the member reaction sensitivity is low, the operation underaction.
The utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of tractor clutch's pedal control structure.It is stepped on flexibly, precise control.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of tractor clutch's pedal control structure, comprise angular transducer, first connecting rod, second connecting rod and pedal assembly, described angular transducer comprises rotor shaft, it is characterized in that, described pedal assembly comprises pedal shaft, pedal arm and pedal, the top of described pedal arm is provided with the axis hole suitable with described pedal shaft, the bottom of described pedal arm is upwards upset of circular arc, described pedal is connected to the lower end of described pedal arm, the outside of described axis hole is provided with pull bar, the two ends of described first connecting rod are articulated and connected with the lower end of described pull bar and an end of described second connecting rod respectively, the other end of described second connecting rod is fixedly connected with the rotor shaft of described angular transducer.
The beneficial effects of the utility model are: simple in structure, flexible operation, save installing space.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described angular transducer is Hall element.
Adopt the beneficial effect of above-mentioned further scheme to be, Hall element work is sensitive, reliable.
The accompanying drawing explanation
Fig. 1 is the practical figure of structure of the present utility model;
Fig. 2 is pedal of the present utility model in free state and steps on the state comparison diagram.
In Fig. 1 and Fig. 2,1, pedal shaft; 2, axis hole; 3, pull bar; 4, first connecting rod; 5, second connecting rod; 6, rotor shaft; 7, angular transducer; 8, pedal arm; 9, pedal.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only be used to explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of tractor clutch's pedal control structure, comprise angular transducer 7, first connecting rod 4, second connecting rod 5 and pedal assembly, described angular transducer 7 comprises rotor shaft 6, it is characterized in that, described pedal assembly comprises pedal shaft 1, pedal arm 8 and pedal 9, the top of described pedal arm 8 is provided with the axis hole 2 suitable with described pedal shaft 1, the bottom of described pedal arm 8 is upwards upset of circular arc, described pedal 9 is connected to the lower end of described pedal arm 8, the outside of described axis hole 2 is provided with pull bar 3, the two ends of described first connecting rod 4 are articulated and connected with the lower end of described pull bar 3 and an end of described second connecting rod 5 respectively, the other end of described second connecting rod 5 is fixedly connected with the rotor shaft 6 of described angular transducer 7.
Described angular transducer 7 is Hall element.
As shown in Figure 2, for pedal of the present utility model in free state with step on the state comparison diagram.When depressing pedal 9, pedal arm 8 is around the pedal shaft clickwise, described pull bar 3 drives first connecting rod 4 upward movements, described first connecting rod 4 drives second connecting rod 5 and rotates around described rotor shaft, angular transducer 7 can be according to the corner size of rotor shaft, to central process unit, send electric signal, central process unit and then send control signal and make clutch smooth and steady action, realize the power-transfer clutch fast speed in conjunction with or separate.
The state when dotted line in Fig. 2 means that pedal 9 is stepped on.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
