The work of preparing International Standards is normally carried out through ISO technical commi

10、ttees. 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-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the I

11、nternational 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 main task of technical committees is to prepare International Standards. Draft Internationa

12、l 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. Attention is drawn to the possibility that some of the elements of this document may be the

14、rnational Standard is to ensure the interchangeability of the mechanical connections on agricultural towing vehicles.

19、 for various attachments 3 Dimensions and marking 3.1 Dimensions (see Figures 1 to 4) 3.1.1 The dimensions 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 (se

20、e Figure 4) is defined by the required movement of the trailer shank according to 3.1.4 and the dimensioning 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

21、the manufacturing quality of the ball-type coupling device such that unintentional uncoupling of the 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 specif

22、ied ball-type trailer shank fixed to the tractor attachment, the shank shall be free to turn so that 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 axi

23、s passing through the coupling point minimum value of 60 on both sides. BS ISO 24347:20052 Angle of pitch: rotation around a horizontal axis passing through the coupling point and perpendicular to the vehicles longitudinal plane of symmetry minimum value of 20, top and bottom. Allowance should be ma

24、de for the towing vehicle being up to 3 from the horizontal, due to the front or rear tyre sizes. Angle of roll: rotation around a horizontal axis passing through the coupling point and located in the vehicles plane of symmetry minimum value of 20, top and bottom. 3.1.5 The yaw requirement of 60, as

25、 shown in Figure 4, may be exceeded when smaller tyres and/or wide track settings are used on the towing vehicle. Decal(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 An

26、nex A. 3.2 Marking The ball-type coupling device shall be permanently marked “ISO 80”, with this marking located on the 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 cou

27、pling device shall be in accordance with Figure 5. 4.2 The ball-type coupling device shall be mounted in the plane of 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

28、possible without any part of the ball-type coupling or its construction, keeper-plate, etc. entering the clearance zone as specified in ISO 500-1 and ISO 500-2 for the PTO and in ISO 5673-2 for the PTO drive shaft. 4.4 Annex B presents the geometrical conditions to be considered generally.
