The traditional rigid body modal test of the engine is basically completed by operating on a real vehicle, and often because of the limitation of the space of an engine cabin and the constraint of the fixed installation position of an engine suspension, the test on the real vehicle is difficult to knock the test through a force hammer, and the fine adjustment of the suspension position is more difficult. In addition, the traditional simplex beam suspension tool rack can only realize suspension movement of a horizontal plane, is fixed in the vertical direction, cannot realize self-adaptation of engines with various sizes, and needs frequent clamp disassembly and assembly even if the position of the horizontal plane is finely adjusted, so that the traditional simplex beam suspension tool rack has certain limitation. The utility model discloses an at least one embodiment of the utility model provides a multiaxis flexible suspension regulation and control frock has included the mobile device, three root shape stands and the suspension mounting platform of three-dimensional regulation formula to can realize the three-dimensional fine setting of suspension.
FIG. 1 is a partial schematic view of an example gearbox side suspension adjustment assembly according to the present invention. As shown, the suspension adjustment device comprises a guide rail 6, an adjustment mechanism (not visible in the figure; an operation mechanism 5 matched with the adjustment mechanism is shown in the figure), an upright 3, a moving mechanism 4 and a suspension mounting platform 1 (comprising a plurality of steel plates 2 thereon). The adjustment mechanism may for example be mounted in the middle of the guide rail 6 and may be fixed at its bottom to a plane such as the ground by for example bolts, the bottom of which is then connected to the upright 3 to effect coupling of the upright 3 to the guide rail 6.
As shown, the axial directions of the guide rail 6, the upright 3 and the suspended mounting platform 1 are mutually orthogonal. The axial direction here means the longitudinal direction of the guide rail 6, the upright 3 and the suspension mounting platform 1, i.e. the direction of the extension of the respective long axes. In general, the axial directions of the guide rail 6, the upright 3 and the suspension mounting platform 1 may correspond to the Y-axis, the Z-axis and the X-axis of the vehicle to which the suspension belongs, respectively. Fig. 4 is an example of a coordinate axis schematic view of a vehicle according to the invention, where applicable, the axial direction of the guide rail 6, the pillar 3 and the suspension mounting platform 1 can be arranged according to the respective coordinate axes of the vehicle shown in fig. 4.
Returning to fig. 1, the upright 3 is coupled to a guide rail 6, the suspended mounting platform 1 is coupled to the upright 3 via a moving mechanism 4, and the suspended mounting platform 1 is used for mounting a suspension (not shown in the figure). Further, the suspension mounting platform 1 may control the axial movement along the guide rail 6 via the adjusting mechanism, and the suspension mounting platform 1 may control the axial movement along the upright 3 via the moving mechanism 4. When the axial movement of the upright 3 along the guide rail 6 is controlled by the adjusting mechanism, the upright 3 will bring other components to follow the movement, thus causing the suspension mounting platform 1 to move along the axial direction of the guide rail 6, thereby realizing the axial movement (e.g., corresponding to the Y-axis direction of the vehicle) of the suspension on the guide rail 6. When the axial movement along the upright 3 is controlled by the moving mechanism 4, the moving mechanism 4 will drive other components to follow the movement, so that the suspension mounting platform 1 also moves along the axial direction of the upright 3, thereby realizing the axial movement (for example, corresponding to the Z-axis direction of the vehicle) of the suspension on the upright 3. On the other hand, the suspension mounting platform 1 may also be movable in its own axial direction (e.g., corresponding to the X-axis direction of the vehicle).
With further reference to fig. 1, the column 3 includes a column body, a bottom steel plate structure and ribbed steel plates (for example, 8 pieces) connecting the column body and the bottom steel plate structure, so as to increase the rigidity of the column 3, wherein the bottom steel plate structure can be welded with the column body, for example, and the ribbed steel plates are welded to the column body and the bottom steel plate structure, respectively. Furthermore, the adjustment mechanism may be a worm drive (not visible in the figures, showing an operating mechanism 5 used in cooperation with the adjustment mechanism). The moving mechanism 4 may be a ratchet mechanism (not visible in the figures). On the other hand, the suspension mounting platform 1 comprises a plurality of stacked (specifically, 2 or 3 layers) steel plates 2, and the axial movement along itself is achieved by the position between the layers of the plurality of steel plates 2. Specifically, for example, each layer of the multi-layered steel plate 2 may include several mounting holes, and the mounting holes of each layer are matched with each other to achieve variation in the position between the layers. After the mounting holes of each layer are aligned, the mounting holes are fixed by fastening screws, for example, so that the layers of the suspension mounting platform 1 can be positioned mutually, and the axial movement along the suspension mounting platform 1 can be realized. One or more of the layers of steel plates 2 may also be arranged at an angle to the suspension mounting platform 1 if the suspension mounting position does not match the suspension mounting platform 1 completely.
FIG. 3 is a partial schematic view of an exemplary engine-side suspension adjustment apparatus according to the present disclosure. Since the engine is mounted in a position different from the transmission case and the suspension configuration is adjusted "as appropriate", the arrangement of the example suspension adjustment device may also differ, and fig. 3 shows the example suspension adjustment device in a substantially symmetrical arrangement to that of fig. 1. As shown in fig. 3, the axial directions of the guide rail 13, the upright 17 and the suspended mounting platform 12 are mutually orthogonal. The axial direction here means the longitudinal direction of the guide rail 13, the upright 17 and the suspension mounting platform 12, i.e. the direction of the extension of the respective long axes. The axial directions of the guide rail 13, the upright 17 and the suspension mounting platform 12 may correspond to the Y-axis, the Z-axis and the X-axis of the vehicle to which the suspension belongs, respectively.

Further, the suspension mounting platform 12 may control axial movement along the guide rail 13 via an adjustment mechanism, and the suspension mounting platform 12 may control axial movement along the upright 17 via a moving mechanism 18. When the axial movement of the upright 17 along the guide rail 13 is controlled by the adjusting mechanism, the upright 17 will bring other components to follow the movement, thus causing the suspension mounting platform 12 to also move along the axial direction of the guide rail 13, thereby realizing the axial movement (e.g., corresponding to the Y-axis direction of the vehicle) of the suspension on the guide rail 13. When the axial movement along the upright 17 is controlled by the moving mechanism 18, the moving mechanism 18 will bring other components to follow the movement, thus causing the suspension mounting platform 12 to also move along the axial direction of the upright 17, thereby realizing the axial movement (e.g., corresponding to the Z-axis direction of the vehicle) of the suspension on the upright 17. On the other hand, the suspension mounting platform 12 may also move in its own axial direction (e.g., corresponding to the X-axis direction of the vehicle).

On the other hand, the suspended mounting platform 12 comprises a stack of multiple layers of steel plates 21, and axial movement along itself is achieved by the inter-layer position of the multiple layers of steel plates 21. Specifically, for example, each layer of the multi-layered steel plate 21 may include several mounting holes, and the mounting holes of each layer are matched with each other to achieve variation in the position between the layers. The mutual positioning of the layers of the suspension mounting platform 12 can be achieved by aligning the mounting holes of the layers and then fixing the mounting holes with fastening screws, for example, so that the axial movement along the suspension mounting platform 12 itself can be achieved.
As shown in fig. 1 and 3, the guide rail 6 (13) is fixedly coupled with a surface parallel to the ground plane, for example, fig. 3 shows that the guide rail 13 is provided with bolt holes 15 for fixing to the ground; and the surface of the suspended mounting platform 1 (12) and the surface parallel to the ground plane are parallel to each other.
On the other hand, fig. 2 is a partial schematic view of an exemplary rear suspension adjustment device according to the present invention, and since the configuration of the suspension can also be adjusted "by the local conditions", the arrangement of the exemplary suspension adjustment device may also be different, for example, the guide rail may be fixedly coupled to the surface parallel to the ground plane, and the surface of the suspension mounting platform 10 may be perpendicular to the surface parallel to the ground plane. As shown, the axial directions of the guide rails, the uprights 7 and the suspended mounting platform 10 are mutually orthogonal. The axial direction here means the longitudinal direction of the guide rail, the upright 7 and the suspended mounting platform 10, i.e. the direction of the extension of the respective long axes. In general, the axial directions of the guide rail, the upright 7 and the suspension mounting platform 10 may correspond to the X-axis, the Z-axis and the Y-axis of the vehicle to which the suspension belongs, respectively. Fig. 4 is an example of a coordinate axis schematic diagram of a vehicle according to the present invention, where applicable, the axial directions of the guide rail, the pillar 7 and the suspension mounting platform 10 may be arranged in accordance with the respective coordinate axes of the vehicle shown in fig. 4, respectively.
