6、e piton BS ISO 6489-4:2004ii iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body inter

7、ested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical

8、 Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the te

9、chnical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IS

10、O shall not be held responsible for identifying any or all such patent rights. ISO 6489-4 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 4, Tractors. ISO 6489 consists of the following parts, under the general title Agricultural ve

12、wing vehicles Part 4: Dimensions of piton-type coupling 1 Scope This part of ISO 6489 specifies the dimensional requirements for the piton-type coupling devices used in the attachment to agricultural towing vehicles of towed, non-balanced trailers and implements equipped with a coupling ring specifi

13、ed in ISO 5692-1. Its purpose is to ensure the interchangeability of the mechanical connections on agricultural towing vehicles. It is applicable only in those cases where the vertical static load does not exceed 30 kN. 2 Normative references The following referenced documents are indispensable for

14、the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

(Revision of ISO 5692:1979) BS ISO 6489-4:20042 4 Dimensions 4.1 The keeper location and

17、 piton-type coupling device dimensions shall be in accordance with Figures 1 and 2. The keeper shall be contained within the maximum metal outline. 4.2 No part of the keeper shall be allowed to extend beyond the hatched clearance lines (maximum metal condition illustrated) shown in Figure 2. 4.3 The

18、 manufacturer is responsible for both the design and the manufacturing quality of the piton-type coupling device. In order to prevent unintentional uncoupling of the hitch-ring when subjected to the maximum design load, the distance between the top of the pin and the keeper shall not exceed 10 mm (s

19、ee Figure 2). 4.4 The yaw requirement of 60 according to ISO 5692-1 is applicable for the device. Large tyres and narrow track settings on the towing vehicle can restrict this angle in service: when smaller tyres and/or wide track settings are used on the towing vehicle, this angle may be exceeded.

20、As this could result in interference, it should be indicated on a decal or decals on or near the assembly, and in the operators manual. Dimensions in millimetres Figure 1 Dimensions of pin 5 Location 5.1 The location of the piton-type coupling device shall be in accordance with Figure 3. 5.2 In orde

21、r to allow for the travel angles defined in ISO 5692-1, the location of the piton-type coupling device shall be in accordance with the following: a) the piton-type coupling device shall be mounted in the plane of the tractor longitudinal axis; b) the pin shall be located as high as possible, without

22、 any part of the pin-type coupling or its construction, keeper-plate, etc. entering the clearance zone specified for the PTO (power take-off) according to ISO 500.
