9、l 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 interested in a subject for which a technical committee has been es
10、tablished 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 Commission (IEC) on all matters of electrotechnical standardi
11、zation. 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 technical committees are circulated to the member bodies for vot
12、ing. 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. ISO shall not be held responsible for identifying any or all suc

16、(E) ISO 2005 All rights reserved 1 Agricultural vehicles Mechanical connections between towed and towing vehicles Dimensions of ball-type coupling device (80 mm) 1 Scope This International Standard specifies the dimensions and location of a ball-type coupling device of 80 mm nominal diameter, whose
17、male part fitted to an agricultural towing vehicle and female part fitted to a towed, non-balanced vehicle provides mechanical connection between the two vehicles, where the downwards vertical static load does not exceed 40 kN. 2 Normative references The following referenced documents are indispensa

21、sions of the ball-type coupling device shall be in accordance with Figures 1 and 2. The keeper shall be contained within the maximum metal outline. 3.1.2 The minimum clearance zone for the keeper (see Figure 4) is defined by the required movement of the trailer shank according to 3.1.4 and the dimen
22、sioning of the shank as shown in Figure 2. It shall be considered in all rotational degrees of freedom. 3.1.3 The manufacturer of the ball-type coupling device is responsible for both the design and the manufacturing quality of the ball-type coupling device such that unintentional uncoupling of the
23、female part from the male part when subject to the maximum design load shall be prevented. The distance between the keeper and the ball centre shall be (65 1) mm (see Figure 3). 3.1.4 With the specified ball-type trailer shank fixed to the tractor attachment, the shank shall be free to turn so that
24、the angles formed with the horizontal situated in the tractors plane of symmetry and passing through the coupling point have the following minimum values. Angle of yaw: rotation around a vertical axis passing through the coupling point minimum value of 60 on both sides. Copyright International Organ

Deca
28、l(s) and the operators manual of the tractor should inform of this possibility, which could result in interference. 3.1.6 Examples of dimensions for the trailer shank are given in Annex A. 3.2 Marking The ball-type coupling device shall be permanently marked “ISO 80”, with this marking located on th
29、e top or side of the trailer shank. The trailer mating connection shall be permanently and visibly marked with a size identification. 4 Location 4.1 The location of the ball-type coupling device shall be in accordance with Figure 5. 4.2 The ball-type coupling device shall be mounted in the plane of
30、the tractor longitudinal axis. 4.3 The centre of the ball shall be located at the distance shown rearwards from the end of the power take-off (PTO) shaft in Figure 5, and as high as possible without any part of the ball-type coupling or its construction, keeper-plate, etc. entering the clearance zon
