But shifting push-and-pull silk is in practical set use procedure, the circular motion of certain angle is also there is with the catanator junction of variator, the actual motion track of wire drawing as shown in Figure 1, gear selecting shift control mechanism 1, wire drawing joint 2 and wire drawing dust cover 3.
Therefore need to design a kind of device, can simulate the situation of shifting push-and-pull silk real vehicle assembling more really, simulating this can along the reciprocating load of one section of circular arc.
Utility model content
In order to solve the problems of the technologies described above, solve the truth of shifting push-and-pull silk in simulation real vehicle assembling fatigue durability test process needed for load, the utility model provide a kind of can the load device of practical requirement.
This load device is made up of three parts: Part I is base, is provided with pin-and-hole and installs bearing pin in the middle of base; Part II is loading activity bar, and be used for realizing the transmission of load, the one end in bar portion press-fits rolling bearing a, coordinates with the pin-and-hole pinned connection of motion bar base, is beneficial to motion bar carries out certain angle rotation around pin-and-hole.Be provided with test specimen load end mounting hole in the middle of loading activity bar, be connected with the load end of shifting push-and-pull silk.The other end of loading activity bar installs rolling bearing b, is convenient to coordinate with guide piece, realizes the to-and-fro movement of load; Three parts are guide piece, guide piece be provided with 2 groups before and after plate washer, 2 groups of guide poles, wherein guide pole one end is individually fixed in the middle of front apron, the other end is arranged in the interstitial hole of backboard (guide effect of holding concurrently), be furnished with stop collar outside the hole of guide pole and backboard, to limit front and rear baffle distance, rear plate washer and ground are fixed, the spring of the sheathed 2 groups of same stiffness of described guide pole, by the push-and-pull load of compression respectively needed for simulation test of spring.
The utility model tool has the following advantages:
1. structure is simple, controls flexible and cheap.
2. can adjust the position of test specimen mounting hole according to demand, realize the to-and-fro movement that the different radius of gyration brings different radian.
3. utilize rolling bearing as the connecting device of dynamic changes process, eliminate significantly and make with other connected modes the movement interference that circular motion brings.

Below in conjunction with accompanying drawing, the utility model is described in further detail.
The actual motion trajectory diagram of Fig. 1 transmission control and wire drawing junction.
The schematic diagram when load device of Fig. 2 the utility model shifting push-and-pull silk simulation real vehicle assembling fatigue durability test does not load.
Fig. 3 the utility model shifting push-and-pull silk simulation real vehicle assembles the schematic diagram during loading of the load device of fatigue durability test.
Embodiment
As shown in Figure 2, be the structural representation of the utility model load device, described device is provided with base 17, loading activity bar 19 and guide piece; Described loading activity bar 19 one end is connected with base 17 with rolling bearing a 4 by bearing pin 18, and the other end of described loading activity bar 17 is provided with rolling bearing b 6, and described loading activity bar 19 is provided with test specimen load end mounting hole 5.
Described guide piece is provided with two, the symmetrical both sides being distributed in loading activity bar 19.
Described guide piece be provided with guide pole 15,16, front apron 7,8, backboard 9,10, stop collar 13,14 and spring 11,12, front apron 7,8 is located at the end side of guide pole 15,16 near rolling bearing b6, the end side away from rolling bearing b 6 of guide pole 15,16 is located at by backboard 9,10, and described spring 11,13 to be sheathed on guide pole 15,16 and at front apron 7, between 8 and backboard 9,10; Described stop collar 13,14 is located at the outside of backboard 9,10.
