Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
The utility model further provides a lower fork arm of an automobile suspension shock absorber, which is described below with reference to specific embodiments, and is shown in fig. 1 and 2, and comprises a first installation part 1 for connecting the shock absorber and a second installation part 2 for connecting a control arm, wherein a connection part 3 is arranged between the second installation part 2 and the first installation part 1, the first installation part 1 comprises a cylinder 11, one side of the cylinder 11 is provided with a slot 111, the position of the slot 111 is provided with a locking part 12, one end of the connection part 3 is connected to one side of the cylinder 11 far away from the locking part 12, and the other end is connected to the second installation part 2. When the cylinder 11 is mounted to the damper by the locking portion 12, the cylinder 11 is deformed to some extent, and the connecting portion 3 is disposed on the side of the cylinder 11 away from the locking portion 12, which is advantageous in reducing deformation of the connecting portion 3 due to deformation of the cylinder 11. In this embodiment, the connecting portion 3 is disposed opposite to the locking portion 12, that is, the center point of projection of the connecting portion 3 on the cylinder 11 and the center point of projection of the locking portion 12 on the cylinder 11 are located on opposite sides of the cylinder 11. This arrangement minimizes the influence of the deformation of the cylindrical body 11 on the connection portion 3, in which case there is little displacement of the position of the second mounting portion 2.
The locking part 12 comprises extension sections 121 arranged at two sides of the slot 111, the extension sections 121 are provided with first through holes 1211 for bolts to pass through, after the cylinder 11 is sleeved on the shock absorber, the cylinder 11 and the shock absorber have a certain fit clearance in assembly, the bolts pass through the first through holes 1211 of one extension section 121 and extend out from the first through holes 1211 of the other extension section 121, then nuts are connected to the bolts and screwed down, and after the fit clearance is eliminated by the locking force exerted by the bolts, the locking effect of the cylinder 11 on the shock absorber is realized.
The second mounting portion 2 includes a main body portion 21, fork arm portions 22 are provided on both sides of the main body portion 21, the fork arm portions 22 extend in a direction away from the first mounting portion 1, and second through holes 221 through which bolts pass are provided on both the fork arm portions 22. The two fork arms are respectively placed on both sides of the control arm, the bolt is passed through the second through hole 221 of one of the fork arm parts 22 and the mounting hole on the control arm, then the end of the bolt is protruded from the second through hole 221 of the other fork arm part 22, and then the nut is connected to the bolt and tightened, i.e., the second mounting part 2 can be fixed to the shock absorber. When the cylinder 11 locks the damper, there is no input of any deformation for the lower end main body portion 21 and the yoke portion 22, so that the yoke portion 22 can maintain a gap in a designed state when assembled with the control arm, and the assembly is easy without any later adjustment.
The side wall of the cylinder 11 is also provided with a side rib 13, and the side rib 13 is provided with a third through hole 131. The third through hole 131 is used for being fixedly connected with the suspension stabilizer bar connecting rod through bolts. Because the suspension stabilizer bar connecting rod is generally in a spherical hinge structure, even if the cylinder 11 is elastically deformed to a certain extent, the suspension stabilizer bar connecting rod can be smoothly assembled through swinging the spherical hinge.
The connecting portion 3 includes a vertical section 31 and an arc transition section 32, the vertical section 31 is connected to the side wall of the cylinder 11, and the arc transition section 32 is connected to the second mounting portion 2. In this embodiment, the arc transition section 32 is connected to one side of the second mounting portion 2, and in other embodiments, the arc transition section 32 may be connected to the top of the second mounting portion 2. It should be noted that, the specific shapes of the vertical section 31 and the circular arc transition section 32 are not limited to the shapes in the drawings, and the length of the vertical section 31 and the angle of the circular arc transition section 32 can be adjusted to a certain extent on the premise of meeting the requirement of structural performance.
In this embodiment, the first mounting portion 1, the second mounting portion 2 and the connecting portion 3 are integrally formed by forging. In other embodiments, the first mounting portion 1, the second mounting portion 2 and the connecting portion 3 may be connected in an assembled manner. However, the connection in the form of an assembly is costly on the one hand and on the other hand affects the fatigue strength, which leads to an increased risk of construction.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
