1、 ANSI/ASABE AD24347:2005 JUN2014 Agricultural vehicles Mechanical connections between towed and towing vehicles Dimensions of ball-type coupling device (80 mm) American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members worldwide, who are

2、dedicated to advancement of engineering applicable to agricultural, food, and biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally

3、agricultural field equipment, farmstead equipment, structures, soil and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Pract

4、ices, and Data are informational and advisory only. Their use by anyone engaged in industry or trade is entirely voluntary. The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance with

5、applicable ordinances, laws and regulations. Prospective users are responsible for protecting themselves against liability for infringement of patents. ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“, regar

6、dless of the revision approval date. Newly developed Standards, Engineering Practices and Data approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard

7、requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected int

8、erests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at an

9、y time. Additionally, procedures of ASABE require that action be taken periodically to reaffirm, revise, or withdraw each standard.

14、ons between towed and towing vehicles Dimensions of ball-type coupling device (80 mm), is an adoption with deviations of the identically titled ISO standard ISO 24347:2005, Agricultural vehicles Mechanical connections between towed and towing vehicles Dimensions of ball-type coupling device (80 mm).

15、 Deviations noted in the following Foreword sections pertain to those provisions where harmonization could not be achieved between ASABE and the International Standard. 0.2 ANSI/ASABE AD24347 specifies the dimensions and location of a ball-type coupling device of 80 mm nominal diameter, whose male p

16、art 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. This standard is intended for higher speed towing applications when the allowa

17、ble speed exceeds 40 km/h. 0.3 Three normative references are listed in ISO 24347:2005. The responsible ASABE committee has reviewed these references and approved the following deviations: 0.3.1 Replace ISO 500-1:2004, Agricultural tractors Rear-mounted power take-off types 1, 2 and 3 Part 1: Genera

The keeper shall be contained within the maximum metal outline. 3.1.2 The minimum clearance zone for the keeper (see Figu

28、re 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 the ma

29、nufacturing 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 specified ba

30、ll-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 pitch: rotation around a horizontal axis passing through the coupling point and perpendicular to the vehicles longitudinal

32、plane of symmetry minimum value of 20, top and bottom. Allowance should be made 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 symm

33、etry minimum value of 20, top and bottom. 3.1.5 The yaw requirement of 60, as 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 int

34、erference. 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 the top or side of the trailer shank. The trailer mating connection shall be permanently and visibly marked

35、 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 the tractor longitudinal axis. 4.3 The centre of the ball shall be located at the distance shown rearward
