Described load maintainer comprises sleeve, spring, front top plate, back top board and sensing device.Wherein said sleeve is fixed on described wherein at least two risers, and described spring, front top plate and back top board are arranged at the sleeve inner cavity.Described front top plate one end is connected with a threaded rod, and described threaded rod is threadedly connected on described one of them riser by sensing device; One end of spring is replaced mutually with the other end of front top plate, and the other end of spring is replaced mutually with an end face of back top board; Fixedly connected with the rotating shaft of steering assembly in push rod other end, described back.
As further improvement, have the sleeve through hole on described at least two risers, described sleeve is fixed in the sleeve through hole of described two risers at least;
As further improvement, have nut bore on described one of them riser, its internal fixation has a nut; The threaded one end of the threaded rod of described front top plate is connected on the nut of this riser.
As further improvement, the center of described sleeve through hole center and nut is on same the axis.
As further improvement, on a top board end face of described front top plate and back top board, be provided with boss structure, described spring is placed in the boss structure of described forward and backward top board and is resisted against forward and backward top board.
As further improvement, described sensing device is a pressure transducer.
Compared with prior art, and prove that this device has solved well and existed in the prior art, when the course of work, occur the technical matters of jam phenomenon easily through practical application; In addition, the utility model is simple in structure firmly, stable and reliable for performance, reduced the relative frictional resistance in the device, its loading characteristic and automobile actual steering load are more approaching, the part throttle characteristics of steering under various road conditions can be simulated, the demand of various steering mechanism test data can be satisfied with.
[description of drawings]
Fig. 1 is the embodiment that spring of the present utility model is regulated charger.
[embodiment]
Also in conjunction with the accompanying drawings the utility model is described in further detail below by concrete preferred embodiment.
See also Fig. 1, the spring of the disclosed a kind of automobile steering system testing table of the utility model is regulated charger, comprises bracket assembly and load maintainer, and load maintainer is set up in bracket assembly.
Described bracket assembly comprises first riser 1, second riser 2, the 3rd riser 3 and double threaded screw 4, and stud bolt 4 passes described each riser successively and fixedlys connected with described each riser formation screw thread.Described load maintainer comprises sleeve 5, spring 6, front top plate 7, back top board 8 and sensing device 10.All have sleeve through hole (not shown) on described first riser 1, second riser 2, sleeve 5 is fixed in the sleeve through hole of first riser 1 and second riser 2.Wherein, have the nut bore (not shown) on the 3rd riser 3, its internal fixation has a nut 12;
Described front top plate 7 one ends are fixedly connected with threaded rod 9, and described threaded rod 9 is threadedly connected on the 3rd riser 3 by described sensing device 10.Described sensing device 10 is a pressure transducer, and described sensing device 10 is electrically connected with the electronic control unit (not shown).
The center of described sleeve through hole center and nut 12 is on same the axis, can effectively reduce like this because of forward and backward top board 7,8 because of not on same axis, and produce relative frictional resistance with sleeve 5.
Forward and backward top board 7,8 and spring 6 are arranged at the internal cavities of sleeve 5, and the diameter of described forward and backward top board 7,8 is slightly less than the internal diameter of sleeve 5, and the inwall of sleeve 5 is very smooth smooth, can effectively reduce extra frictional resistance like this.In addition, be respectively equipped with boss structure 11 on the end face of forward and backward top board 7,8; One end of spring 6 is sheathed on the boss structure 11 of front top plate 7, and replaces mutually with this end face; The other end of spring 6 is sheathed on the boss structure 11 of back top board 8, and replaces mutually with this end face; Described back top board 8 other ends are fixedlyed connected with the rotating shaft 13 of steering assembly.
The spring of this automobile steering system testing table regulate charger by about the spring of two same structures regulate charger and constitute.Regulate in the course of work of charger at this spring, in order to simulate different road conditions, by the threaded rod 9 that reverses front top plate 7, front top plate 7 is moved forward and backward with respect to back top board 8 in sleeve 5, and then the initial position state of the elastic modulus of adjustable springs 6 or spring 6 (initial compression when steering wheel does not rotate or amount of tension) can be simulated the pavement test condition (it is different with the friction factor between the road surface to be equivalent to wheel) under the situation of different road surfaces.Regulating charger with left spring below is example, and its course of work is described.
The course of work: at first steering wheel is rotated to initial 0 angle, can be by manually reversing the threaded rod 9 of front top plate 7 clockwise, make front top plate 7 in sleeve 5, axially move, the certain decrement of spring 6 generations this moment, front top plate 7 location towards the direction of back top board 8; Pressure transducer 10 is gathered the pressure signal of this moment, is the required original pressure value that obtains.
When steering wheel rotates counterclockwise, spring is regulated in the charger, the back top board 8 that is connected with the rotating shaft 13 of steering assembly moves towards the direction away from front top plate 7 in the axial direction, and then make the decrement of replacing the spring 6 on forward and backward top board 7,8 change, certain recovery of elasticity takes place in spring 6 on the axial direction of sleeve 5, spring 6 produces linear transformation power, and pressure transducer 10 is gathered the pressure signal in this process of transmission in real time.
Accordingly, in the above-mentioned course of work, regulate in the charger at right spring, by identical method, the spring that right spring is regulated in the charger produces certain decrement, and pressure transducer collection pressure signal at this moment is the required original pressure value that obtains.
When steering wheel rotated counterclockwise, the spring in the right spring adjusting charger was compressed in the axial direction in sleeve and shortens, and spring produces corresponding linear transformation power, and pressure transducer is gathered the pressure signal in this process of transmission in real time.
