Embodiment
The varying load realization of loading.In Fig. 1 and Fig. 2, bracket assembly (5) is fixed, and four spring base guide poles (7) are fixed its position by the hole on the bracket assembly by nut (3) and nut (9), and rear spring seat (13) is porose, is installed on the spring base guide pole (7) by nut (8); The structure of front spring seat (4) is identical with rear spring seat (13), limits it by bracket assembly (5) and goes up the position at spring base guide pole (7); Loading spring (6) is contained between rear spring seat (13) and the front spring seat (4), and makes front spring seat (4) against bracket assembly (5).Steering gear (2) is by the front spring seat (4) of pull pressure sensor (1) against charger.Front spring seat (4) and rear spring seat (13) right part middle and bracket assembly (5) has the hole, sensor guide pole (11) one ends connect pull pressure sensor (1), the other end passes the hole in the middle of preceding spring abutment (4) and the rear spring seat (13), and pass through nut (10), and pass the right part of bracket assembly (5) against rear spring seat (13).Steering gear (2) output terminal and pull pressure sensor (1), sensor guide pole (11) link together, and they move together.Friction force is regulated bolt (12) and is pressed on the sensor guide pole (11) by cushion (16) and friction pad (17); Can go up at sensor guide pole (11) and produce friction.
During work, when steering gear (2) output terminal when middle position moves right, then promote pull pressure sensor (1), front spring seat (4) compression-loaded spring (6) is realized loading; Sensor guide pole (11) moves right simultaneously, and friction force is regulated bolt (12) and also is added on steering gear (2) output terminal by sensor guide pole (11) by the friction force that cushion (16) and friction pad (17) apply.When steering gear (2) output terminal when middle position is moved to the left, then spur pull pressure sensor (1), sensor guide pole (11), nut (10), rear spring seat (13) compression-loaded spring (6) and realize loading; Friction force adjusting bolt (12) also is added on steering gear (2) output terminal by sensor guide pole (11) by the friction force that cushion (16) and friction pad (17) apply simultaneously.
The size of loading force can come the rigidity of regulating spring to realize by regulating spring rigidity regulating device A (14), spring rate regulating device B (15) on the one hand, because the load of steering gear (2) output terminal that is applied to loading spring (6) depends on the displacement of output terminal and the product of loading spring (6) rigidity, under the situation of certain displacement, the rigidity that changes loading spring (6) just can change and is applied to the load that steering gear (2) output terminal applies; Can realize different friction force by regulating friction force adjusting bolt (12) on the other hand, because friction force is regulated the increase of bolt (12) applied pressure along with friction force and increased.The various combination of two aspects just can be realized the loading of different qualities.
The Principles of Regulation of spring rate are as follows.For cylindroid helical-coil compression spring, its rigidity and number of active coils are inversely proportional to, and change number of active coils and just can change rigidity.Principles of Regulation are seen Fig. 2, spring rate regulating device B (15) are placed in the middle of the pitch of spring centre, make 1 coil spring inoperative, and the number of active coils of spring just reduces 1.
Fig. 3 is that the number of active coils of regulating spring is less than 1 embodiment, because loading spring of the present utility model (6) is by compression, each 1 circle of two ends is also tight and polish, so the pitch of the bracing ring at first coil and last coil and two ends gradually changes, like this spring rate regulating device A (14) being placed on the appropriate location will suitably reduce the number of active coils of spring, during such as 1/4 coil that is placed on from bracing ring, total number of active coils just reduces 1/4; When being placed on 1/2 coil from bracing ring, total number of active coils just reduces 1/2, and the like.
When the number of active coils that needs loading spring (6) reduces to be worth for greater than 1 non-integer the time, can adopt above two kinds of methods simultaneously, also can adopt the embodiment method of Fig. 4, wherein adopt two spring rate regulating device B (15).Position shown in Figure 4 can be so that loading spring (6) number of active coils reduces 1.5; By two spring rate regulating device B (15) are placed on diverse location, can make loading spring (6) number of active coils reduce numerical value is between 1 to 2.
When the number of active coils that needs loading spring (6) reduces to be worth for greater than 1 integer the time, need place the spring rate regulating device B (15) of corresponding number along the axis direction of spring.The embodiment of Fig. 5 can reduce 2 to the number of active coils of loading spring (6).
Loading spring (6) also can adopt the trochoid spiral compression spring, like this when adopting above method, and number of active coils that not only can regulating spring, and can change the mean diameter of spring, at this moment the effect of regulating spring rigidity is more obvious.
Fig. 2, Fig. 3, Fig. 4, Fig. 5 also are the embodiment that loads friction force.Friction force is regulated bolt (12) by cushion (16), friction pad (17) jam sensor guide pole (11).The pretightning force of regulating friction force adjusting bolt (12) just can obtain needed friction force.Cushion (16) is to regulate the elasticity that compresses of bolt (12) in order to increase friction force, thereby keeps friction stability.
In Fig. 6, unscrew nut (8) and nut (10) after, make it not against rear spring seat (13).Like this, when steering gear (2) output terminal when middle position moves right, then promoting pull pressure sensor (1), front spring seat (4) and rear spring seat (13) moves right together, loading spring (6) is imposed load not, the load that applies has only friction force to regulate the friction force that bolt (12) applies by cushion (16) and friction pad (17), and this friction force is added on steering gear (2) output terminal by sensor guide pole (11).When steering gear (2) output terminal when middle position is moved to the left, then promote pull pressure sensor (1) and sensor guide pole (11) is moved to the left together; Because nut (10) is not against rear spring seat (13), so loading spring (6) is not compressed, imposed load not, the load that applies has only friction force to regulate the friction force that bolt (12) applies by cushion (16) and friction pad (17), and this friction force is added on steering gear (2) output terminal equally by sensor guide pole (11).After the pretightning force of friction force being regulated bolt (12) mixed up, friction force had also been determined, so just can realize waiting load to load.
