AI Technical Summary
When installing the anti-roll linkage, relative rotation can easily occur between the linkage body, the connecting ball head, and the anti-roll nut, resulting in low installation efficiency and requiring multiple operators to fix it in place to complete the installation of one anti-roll nut.
A positioning device is adopted, including a clamping component and a tightening bolt. The clamping component is circumferentially limited to the rod body, and the tightening bolt abuts against the bogie. The rotation of the rod body and the anti-loosening washer is restricted by the limiting part and the positioning groove, and the anti-rotation component restricts the rotation of the connecting ball head, thereby improving the installation efficiency.
It reduces manual intervention, improves the efficiency of nut installation, prevents repeated tightening and adjustment of connecting ball heads, and enhances overall installation efficiency.

Abstract
Claims
1. A positioning device for an anti-roll link of a rail vehicle, the anti-roll link comprising a rod body and a connecting ball head threadedly connected to the rod body, wherein a nut is provided on the rod portion of the connecting ball head for abutting against the end of the rod body; Its features are, The positioning device includes: A clamping component is detachably disposed between the rod and the bogie of the rail vehicle for circumferential limiting engagement with the rod; Tighten the bolts, which are threadedly connected to the clamping parts, for contact with the bogie.
2. The positioning device of claim 1, wherein, The clamping element includes: The base is disposed between the rod and the bogie and is threadedly connected to the top bolt; A pair of limiting parts are provided protruding from the base toward the rod body; The rod body is provided with at least one slot, and the limiting part is attached to the bottom surface of the slot to limit the rod body in a circumferential direction.
3. The positioning device of claim 2, wherein, At least one slot is provided near the end of the rod, and the clamping member engages with the slot near the end of the rod.
4. The positioning device according to claim 3, wherein the anti-roll link further includes an anti-loosening washer disposed between the end of the nut and the rod body; characterized in that The limiting part is provided with a positioning groove for circumferentially limiting the anti-loosening gasket, and the positioning groove is used to accommodate the locking lug of the anti-loosening gasket.
5. The positioning device of claim 4, wherein, The clamping member has a clearance portion on the side near the nut, which is used to accommodate the washer body of the anti-loosening washer.
6. The positioning device of claim 5, wherein, The avoidance part includes: A first clearance groove is provided on the side of the base near the nut; There are two second clearance grooves, which are respectively disposed on the pair of limiting parts and connected to the two ends of the first clearance groove.
7. The positioning device according to any one of claims 1-6, characterized in that, The positioning device further includes: A support member is disposed between the bogie and the clamping member and abuts against the tightening bolt.
8. The positioning device of claim 7, wherein, The support member has a pair of protruding hanging ears, which are symmetrically arranged on both sides of the support member.
9. The positioning device according to claim 7, characterized in that, The bogie is provided with a mounting seat for mounting the connecting ball joint, the mounting seat comprising: The first support part is connected to the bogie by screws, and the support part abuts against the screws; The second support portion protrudes outward from the first support portion and is used to install the connecting ball head.
10. The positioning device of claim 9, wherein, The positioning device further includes: An anti-rotation component is detachably mounted on the second support portion to restrict the circumferential rotation of the connecting ball head about the axis of the rod body. The anti-rotation component has a protruding disassembly part for removing it.
