1、 ANSI/ASABE AD11001-1:2016 NOV2016 Agricultural wheeled tractors Three-point hitch couplers Part 1: U-frame coupler American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members worldwide, who are dedicated to advancement of engineering appl
2、icable 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 agricultural field equipment, farmstead equi
3、pment, 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 Practices, and Data are informational and advisor
4、y 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 applicable ordinances, laws and regulations.
5、 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“, regardless of the revision approval date. Newly d
6、eveloped 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 requires verification by ANSI that the requi
7、rements 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 interests. Substantial agreement means much mor
8、e 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 CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Additionally, procedures of ASABE re
9、quire that action be taken periodically to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

Deviations noted in the following Foreword sections pertain to those provisions where harmonization could not be achieved between ASABE and the International Standard. Deviations from
17、 the subsequently printed international standard are noted with underscore (addition) or strikethrough (deletions) text. Deviations from the international standard figures and equations are clearly marked. 0.2 This part of ISO 11001 specifies the essential dimensions for the attachment of three-poin

NOTE In general the dimensions associated with the tractor and implement for use
19、with hitch couplers are the same as those for the three-point linkage specified in ANSI/ASABE AD730:2009 W/Amd. 1:2014 or ANSI/ASABE AD8759-1:1998, and those for the clearance zone specified in ISO 2332. The three-point hitch coupler systems constitute a special method of implement mounting. The hit

Due to the special construction and function of hitch couplers, it can be necessary to vary the length of the upper and lower links indi

30、ors equipped with a three-point free link hitch according to ISO 730 ANSI/ASABE AD730:2009 W/Amd. 1:2014 or ISO 8759-1 ANSI/ASABE AD8759-1:1998 and a U-frame hitch coupler.

37、s Front-mounted equipment Part 1: Power take-off and three-point linkage 3 Principle of frame coupler system A frame coupler system is a one-phase implement coupler where the three-point linkage of the tractor (see ISO 730 ANSI/ASABE AD730:2009 W/Amd. 1:2014 or ISO 8759-1 ANSI/ASABE AD8759-1:1998) i
38、s fitted with a U- frame and the implement has the provisions to be mounted to the frame. Hitching and unhitching can be operated from the tractor operators seat. 4 Coupler dimensions Coupler dimensions shall comply with Figure 1 and Table 1. 4.1 The upper hook offset (dimension B5) shall be not mor
39、e than 15,75 mm greater or 6,35 mm less than the lower socket offset (dimension B1). 4.2 The implement shall provide a minimum clearance h3, (see Figure 2 and Table 2) when attached to the coupler to permit lowering all elements of the coupler to ensure satisfactory attachment and detachment of the
40、implement from the coupler. NOTE Older legacy implements may only have clearances of 120,9 mm for categories 1, 2N, 2, 3N, and 3, and 146 mm minimum for categories 4N and 4. 4.3 The upper hook of the quick coupler shall be centred between the lower sockets within 3 mm. 4.4 The lower implement attach
41、ing point on the quick-attaching coupler shall be located in the vertical position such that the lift range, power range and levelling adjustment, as specified in ISO 730 ANSI/ASABE AD730:2009 W/Amd. 1:2014 or ISO 8759-1 ANSI/ASABE AD8759-1:1998 are fulfilled. 4.5 Implement components, other than th
42、e hitch pins, that are in alignment with the lower socket width (dimension A1) shall not extend forward of the centreline of the lower socket for a distance of h5 (see Figure 2 and Table 2) above the lower socket. Components above this height, extending laterally more than l3 (see Figure 2 and Table
43、 2) from the coupler centreline, shall not extend more than 25 mm forward of the vertical centreline through the upper hook opening. 4.6 The lower socket width (A1) shall be maintained within the area defined by dimensions B2, H6, H7 and B9.

44、ty of Agricultural and Biological Engineers 4 4.7 The lower link to coupler pins may be recessed to provide design freedom to obtain structural integrity in the coupler frame, resulting in a common dimension for L3 and L6, and L4 and L7, respectively. 4.8 Note that ISO 730 specifies that dimension L
45、 in Table 2 shall have a range of 75 mm for hitch categories 1, 2N, and 2 and a range of 100 mm for hitch categories 3N, 3, 4N, and 4. Dimension B1 in this part of ISO 11001 allows the lower socket offset to be larger than the range allowed in ISO 730. For tractors designed with U-frame couplers as
46、standard equipment, the lower links should be shortened so that the distance to the lower U-frame coupler jaw falls within the range for dimension L specified in ISO 730 ANSI/ASABE AD730:2009 W/Amd. 1:2014. For tractors that offer U-frame couplers as an option, the lower links should be designed to
47、the minimum L dimension given in ISO 730 ANSI/ASABE AD730:2009 W/Amd. 1:2014 as far as possible to minimize the distance that the combined lower link and U-frame coupler length is over the upper limit of the L dimension given in ISO 730 ANSI/ASABE AD730:2009 W/Amd. 1:2014. NOTE For hitch Category 1,
48、 dimension B1 in this part of ISO 11001 means the lower socket offset may be larger than the range allowed in ANSI/ASABE AD730:2009 W/Amd. 1:2014. 4.9 For U-frame couplers that by design can be converted to different hitch categories, dimensions H6, H7, H5, L4, L2, L5 and L3 may not be achieved in a
49、ll configurations.
