BS ISO 3584:2020 pdf free.Road vehicles一Clevis couplings一Interchangeability
This document specifies the characteristics necessary for the mounting and interchangeability of clevis couplings on the frame (cross member, drawbeam or mounting bracket) of towing vehicles for trailers.This document is applicable to clevis couplings intended for connection to trailers equipped with a drawbar eye on the drawbar of the trailer.Characteristics not specified are left to the discretion of the component manufacturer.

Reference may be made to this document both for clevis coupling mounting dimensions on the frame and for the separate clevis coupling.
Frames in conformance with this document shall be identified by the following information, in the order given:
a) reference to this document;
b) number of the category according to Table 1.
EXAMPLE Frames with mounting dimensions according to category 3:Crossmember (or drawbeam or mounting bracket) ISO 3584一Category 3 Dimensions on the frame required for mounting of the clevis coupling (see Figure 2), such as the minimum flat surface defined by dimensions F and G, shall be as given in Table 2. Tolerances on drilling pattern dimensions shall be as shown in Figure 1.
In order to permit safer operation of the clevis coupling, there shall be adequate free space around actuating devices. Dimensions needed to ensure operating clearance for actuating devices are also shown in Figure 3.BS ISO 3584 pdf free download.
