The work

6、 of preparing International Standards is normally carried out through ISO technical committees. Each member body interested 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-governmen

7、tal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical 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 ma

8、in task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical 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. At

9、tention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

11、sions of piton-type coupling BS ISO 6489-4:2004blank 1Agricultural vehicles Mechanical connections between towed and towing 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 attachme

12、nt to agricultural towing vehicles of towed, non-balanced trailers and implements equipped with a coupling ring specified 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 verti

13、cal static load does not exceed 30 kN. 2 Normative references The following referenced documents are indispensable for 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 amendmen

ISO 500 (all parts), Agricultural tractors Rear-mounted power take-off types 1, 2 and 3 ISO 5692-1: 1), Agricultural vehicles Mechanical connections on towed vehicles Part 1: Dimensions for hitch-rings 3 Terms and definitions For the purposes of this document, the following terms and de

15、finitions apply. 3.1 piton-type coupling device coupling device consisting of a pin (see Figure 1), mounting part and keeper 3.2 mounting part part needed to mount the pin and the keeper to an agricultural vehicle or to its mounting frame 3.3 keeper part that prevents unintentional uncoupling of the

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

17、be allowed to extend beyond the hatched clearance lines (maximum metal condition illustrated) shown in Figure 2. 4.3 The 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 whe

18、n subjected to the maximum design load, the distance between the top of the pin and the keeper shall not exceed 10 mm (see 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 angl

19、e in service: when smaller tyres and/or wide track settings are used on the towing vehicle, this angle may be exceeded. 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 Dimension

20、s of pin 5 Location 5.1 The location of the piton-type coupling device shall be in accordance with Figure 3. 5.2 In order 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

21、shall be mounted in the plane of the tractor longitudinal axis; b) the pin shall be located as high as possible, without 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.
