The work

9、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-government

15、nd edition cancels and replaces the first edition (ISO 11001-1:1993), which has been technically revised.ISO 11001 consists of the following parts, under the general title Agricultural wheeled tractors Three-point hitch couplers: Part 1: U-frame coupler Part 2: A-frame coupler Part 3: Link coupler P

16、art 4: Bar coupleriv ISO 2016 All rights reservedBS ISO 11001-1:2016INTERNATIONAL STANDARD ISO 11001-1:2016(E)Agricultural wheeled tractors Three-point hitch couplers Part 1: U-frame coupler1 ScopeThis part of ISO 11001 specifies the essential dimensions for the attachment of three-point hitch imple

17、ments to agricultural wheeled and track-laying tractors equipped with a three-point free link hitch according to ISO 730 or ISO 8759-1 and a U-frame hitch coupler.NOTE In general the dimensions associated with the tractor and implement for use with hitch couplers are the same as those for the three-

18、point linkage specified in ISO 730 or ISO 8759-1, and those for the clearance zone specified in ISO 2332.The three-point hitch coupler systems constitute a special method of implement mounting. The hitch couplers are an additional component located between the three-point linkage and the implement,

19、making it possible to hitch and unhitch from the operators seat. Due to the special construction and function of hitch couplers, it can be necessary to vary the length of the upper and lower links indicated in the referenced standards.This part of ISO 11001 applies to categories 1, 2N, 2, 3N, 3, 4N,

20、 and 4 of agricultural wheeled and track-laying tractors as defined in ISO 730 or ISO 8759-1.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

22、hree-point linkage Clearance zone around implementISO 8759-1, Agricultural wheeled tractors Front-mounted equipment Part 1: Power take-off and three-point linkage3 Principle of frame coupler systemA frame coupler system is a one-phase implement coupler where the three-point linkage of the tractor (s

23、ee ISO 730 or ISO 8759-1) is 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 dimensionsCoupler dimensions shall comply with Figure 1 and Table 1.4.1 The upper hook offset (dimensi

24、on B5) shall be not more than 15,75 mm greater or 6,35 mm less than the lower socket offset (dimension B1). ISO 2016 All rights reserved 1BS ISO 11001-1:2016ISO 11001-1:2016(E)4.2 The implement shall provide a minimum clearance h3, (see Figure 2 and Table 2) when attached to the coupler to permit lo

25、wering all elements of the coupler to ensure satisfactory attachment and detachment of the 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 coupl

26、er shall be centred between the lower sockets within 3 mm.4.4 The lower implement attaching 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 or ISO 8759-1 are fulfilled.4.5 Implement

27、 components, other than the 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 l

28、3(see Figure 2 and Table 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, H7and B9.4.7 The lower link to coupler pins ma

29、y be recessed to provide design freedom to obtain structural integrity in the coupler frame, resulting in a common dimension for L3and L6, and L4and L7, respectively.4.8 Note that ISO 730 specifies that dimension L in Table 2 shall have a range of 75 mm for hitch categories 1, 2N, and 2 and a range

30、of 100 mm for hitch categories 3N, 3, 4N, and 4. Dimension B1in 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 standard equipment, the lower links should be shortened so that the distance to the low

31、er U-frame coupler jaw falls within the range for dimension L specified in ISO 730. For tractors that offer U-frame couplers as an option, the lower links should be designed to the minimum L dimension given in ISO 730 as far as possible to minimize the distance that the combined lower link and U-fra

32、me coupler length is over the upper limit of the L dimension given in ISO 730.4.9 For U-frame couplers that by design can be converted to different hitch categories, dimensions H6, H7, H5, L4, L2, L5and L3may not be achieved in all configurations.2 ISO 2016 All rights reservedBS ISO 11001-1:2016ISO
