In order to solve the technical problem, the utility model provides a technical solution as follows:
a ball pin structure for realizing suspension frame overturn is characterized in that:
the ball pin locking device comprises a ball pin, a ball pin seat, a locking nut, a mounting seat and two bearings;
the mounting seat is provided with a mounting hole, the hole wall of the mounting hole is matched with the side wall of the ball pin seat, two fixing shafts are fixedly connected to opposite positions on the side wall of the mounting seat, and the axes of the two fixing shafts are perpendicular to the axis of the mounting hole;
the two bearings are respectively arranged on the two fixed shafts;
the ball pin comprises a ball head and a pin end, the ball head is mounted in the mounting hole through a ball pin seat, and the locking nut is mounted at the pin end.
Further, the clamping device further comprises two clamping springs, and the two clamping springs are respectively sleeved at the end parts of the two fixing shafts.
Furthermore, the oil seal device also comprises two oil seal rings, wherein the two oil seal rings are respectively sleeved on the two fixed shafts, and the end surfaces of the two sides of each oil seal ring are respectively contacted with the mounting seat and the bearing.
Further, the bearing adopts a needle bearing.
The utility model discloses compare the beneficial effect that prior art has:
the utility model provides a ball round pin structure for realizing suspension upset can make on the suspension control arm revolute the knuckle tip through ball round pin structure and overturn, on the basis of current ball round pin structure, increases a revolute pair degree of freedom, the in-process of whole suspension upset, it uses the fixed point to be the nearly 180 degrees of shaft rotation to go up the control arm, the limited problem of current ball round pin structure swing angle has been overcome, so that realize the upset of amphibious car suspension, and then fold the wheel in the frame bottom, the operating speed has been improved.
