The steps when the shock absorber is assembled with the shock absorber are as follows:
as shown in fig. 1 and 4, the pre-tightening positioning piece 4 is installed, so that the first inserting part 41 and the second inserting part 45 are respectively pre-inserted into the first inserting groove 31 and the second inserting groove 35, and the positioning plate 44 is positioned in the installation hole 11;
in this embodiment, since the installation, positioning and pre-tightening of the damper are integrated into one action, the required force is large, and the assembly is generally completed, the steering knuckle is placed on the fixed tool, the damper 2 is pushed into the installation hole 11 by a device with a pushing function (such as a cylinder or a hydraulic cylinder), the damper (generally a liquid storage cylinder) gradually enters the installation hole 11 in the pushing process, and pressure is applied to the positioning plate 44, under the action of the pressure, the first inserting part 41 and the second inserting part 45 are gradually inserted into the first inserting groove 31 and the second inserting groove 35, and under the action of the second inserting part 45 with a wedge shape and under the action of the inner wall of the inserting groove, the locking lugs 3 on both sides are tensioned, when the first inserting part 41 and the second inserting part 45 are inserted into the bottom, the positioning plate 44 moves to the lower part of the installation hole 11, the damper cannot be continuously inserted, and the positioning and pre-tightening effects are achieved, and the effect of quick installation and positioning of the damper and the steering knuckle is achieved.
In the prior art, a plate for positioning the mounting position of the shock absorber is welded at the bottom of a mounting hole on the knuckle, and the welding step is omitted.
After the above steps are completed, the bolt 5 is used to pass through the locking lug 3 and/or the first insertion part 41 and the second insertion part 45
The nut 6 is installed at the other end of the bolt 5 to tighten the through hole, and the connecting part 42 deforms in the tightening process, so that the first inserting part 41 and the second inserting part 45 can be subjected to interval adjustment, and the deformed connecting part 42 can play a certain anti-loosening role.
In this embodiment, as shown in fig. 3, one slot is disposed at the middle position of one side locking lug 3 for inserting the wedge-shaped insertion part, and the other slot is disposed at the end position of the other side locking lug 3 for being disposed towards the outside opening, so that the pretension positioning member 4 can be conveniently taken out when the pretension positioning member is detached.
Alternatively, the slot may be a pass-through or a non-pass-through.
Embodiment two: on the basis of the first embodiment, the bracket 43 can extend into the expansion joint 12 on the damper mounting portion 1 when not pre-tightening, the width of the bracket 43 is larger than the width of the expansion joint 12 after pre-tightening of the damper mounting portion 1, that is, when the second inserting portion 45 is gradually inserted, the width of the expansion joint 12 gradually decreases, and when the second inserting portion 45 is inserted to the maximum depth, as shown in fig. 5, the positioning plate 44 moves below the mounting hole 11 at this time, the bracket 43 is located below the expansion joint 12, and because the damper mounting portion 1 has a tendency of loosening, the inserting portion is likely to be extruded, and because the width of the bracket 43 is larger than the width of the expansion joint 12 after pre-tightening of the damper mounting portion 1, the pre-tightening positioning member 4 has a self-locking effect, thereby ensuring the pre-tightening effect and avoiding pre-tightening failure.
