Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present utility model is described in more detail.Although show exemplary embodiment of the present utility model in accompanying drawing, however should be appreciated that can realize the utility model in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the utility model can be understood, and complete for scope of the present utility model can be conveyed to those skilled in the art.
Embodiment
In trap for automobile simulation test, usual employing four column testing table actuator carries out real test, but due in process of the test, dust in the dust of vehicle chassis or surrounding air can be stained with on the piston rod that actuator assembly exposes, dust on piston rod can enter in piston/cylinder along with the to-and-fro movement of piston rod in piston/cylinder, and then makes actuator assembly unnecessary wearing and tearing occur and shorten its serviceable life.In order to avoid this unnecessary wearing and tearing, as shown in Figure 1, embodiment of the present utility model provides a kind of trap for automobile simulator stand actuator assembly, comprising: testing table body 1, piston/cylinder 2, piston rod 3, test pallet 4 and dust guard 5.Wherein, with the similar of existing actuator, piston/cylinder 2 of the present utility model is fixed on testing table body 1, piston rod 3 matches with piston/cylinder 2, piston rod 3 can be reciprocating in piston/cylinder 2, and the free end of piston rod 3 is provided with the test pallet 4 for bearing automobile wheel.With the structure of existing actuator unlike, trap for automobile simulator stand actuator assembly of the present utility model is also provided with the dust guard 5 that is sheathed on piston rod 3 outside, the two ends of this dust guard 5 respectively with piston/cylinder 2 with test pallet 4 and be connected, namely piston rod 3 is realized to be isolated from the outside, efficiently avoid the wearing and tearing caused because dust enters piston cylinder inside, add the serviceable life of actuator assembly.
Alternatively, as Fig. 1, shown in Fig. 2 and Fig. 4, automobile is being carried out in the test of road analogy, need to drive test pallet 4 to rotate vertically, the road analogy realized automobile with driving automobile vehicle wheel rotation, in order to avoid causing dust guard 5 to be entangled in problem on piston rod 3 owing to testing the rotation of pallet 4, dust guard 5 is except comprising: for separator piston bar 3 and extraneous dustproof part 51, and for outside the first installation portion 52 of being connected of test pallet 4, dust guard 5 also comprises: the hunting gear 54 that can move with dustproof part 52, and for connecting the second installation portion 53 of dustproof part 51 and hunting gear 54.Wherein, hunting gear 54 is fixed on piston/cylinder 2 relative to the other end of the second installation portion 53.
Alternatively, the structure that can realize follow-up action is too numerous to mention, and the present embodiment is only illustrated with structure as shown in Figure 3, and this hunting gear comprises: the first fixed part 541, second fixed part 542 and bearing 543.Wherein, the inner ring interference fit of the first fixed part 541 and bearing 543, for being fixedly connected with piston/cylinder; The outer ring interference fit of the second fixed part 542 and bearing 543, for being connected with the second installation portion.Piston/cylinder is so just made to be connected with the second fixed part 542 of hunting gear, second fixed part 542 is connected with the second installation portion, second installation portion is connected with dustproof part, dustproof part is connected with the first installation portion, first installation portion is connected with test pallet, with this realize piston/cylinder by dust guard with test the hermetically-sealed construction that is connected of pallet.When in simulation test process, test pallet rotates vertically, drive dustproof part to rotate thereupon, utilize bearing can around the characteristic of axial rotation, hunting gear can be realized rotate along with the rotation of dustproof part, therefore avoid and to test because piston/cylinder is motionless that pallet rotates and the dust guard that causes twines problem on the piston rod.
