Operation principle of the present utility model:
Such as Fig. 1, shown in Fig. 3, what steering wheel 1 was locked in turning-bar 2 turns on the body of rod 23, the casing mounting seat 21 of turning-bar 2 is bolted on the top board 32 of turning-bar housing 3, the rotor 51 with angular displacement sensor 5 is turned to bottom the body of rod 23 to be connected, and the housing of angular displacement sensor 5 is fixed on the bottom of turning-bar housing 3 dividing plate 33, the body of rod 23 is turned to be threaded connection with block 42, two springs 44 are enclosed within turning-bar 2 and are separately mounted to the upper-lower position of block 42, block 42 and two springs 44 are fixed on inner support 41 together, inner support 41 is bolted with turning-bar housing 3.Steering wheel rotation 1 can drive and turn to the body of rod 23 to rotate, thus drives the rotor 51 on angular displacement sensor 5 to rotate, thus controls turning to of loader.
Described steering wheel rotation 1 can drive and turn to the body of rod 23 to rotate, the body of rod 23 is turned to be threaded connection with block 42, when turning to the body of rod 23 to rotate clockwise, block 42 is due to the restriction of both sides bolt 43, can not rotate together along with turning to the body of rod 23, upwards move along a straight line only along the thread segment 2331 turning to the body of rod 23, during moving upward, block 42 can extrude upper springs 44, increase along with amount of compression, the elastic force that upper springs 44 gives block 42 downward can be the biggest, and at this moment the operating physical force of steering wheel rotation 1 is the biggest；
Otherwise, when turning to the body of rod 23 to rotate counterclockwise, block 42 can move along a straight line downwards, during moving downward, block 42 can extrude lower springs 44, along with the increase of amount of compression, spring 44 can be the biggest to block 42 elastic force upwards, and at this moment the operating physical force of steering wheel rotation 1 is the biggest；This force variation by spring 44 realizes the force feedback function of direction of operating dish 1.
Bolt 43 is locked on block 42 through the limit guide groove 413 on inner support about 41 two boards；When block 42 upwardly or downwardly moves, bolt 43 can move together with block 42, and when the up-and-down boundary of limit guide groove 413 encountered by bolt 43, block 42 cannot move up and down again, and at this moment steering wheel 1 also cannot have rotated, thus realizes limit function.
It should be understood that the angle (A) that the distance (S) that block 42 and bolt 43 move up and down is the pitch (P) by thread segment 2331 and steering wheel rotation determines, the length (L) of limit guide groove 413 is the pitch (P) by thread segment 2331 and the rotational angle (A of steering wheel maximummax) determine, in steering wheel maximum rotation angle it has been determined that in the case of, in order to obtain suitable limit guide groove length, can obtain by changing pitch (P)；In order to obtain suitable steering wheel operation power, can be obtained by the coefficient of elasticity (K) changing pitch (P) and spring 44, its change pitch (P) by change thread segment 2331 diameter (D) and form of thread and can be modified according to GB relevant regulations, its change spring constant (K) can be modified by changing the parameter such as spring material, line footpath, by above-mentioned setting, determine the pitch (P) of thread segment 2331 and the length (L) of limit guide groove 413, thus obtain suitable steering wheel operation force feedback function and required angle of rotation scope.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
