5、Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards institutes (IS0 member bodies). The work of developing Inter- national Standards is carried out through IS0 technical committees. Every member body interested in a subject for which a te
6、chnical committee has been set up 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. Draft International Standards adopted by the technical committees are circulated to the member bodies
7、for approval before their acceptance as international Standards by the IS0 Council. International Standard IS0 5889 was developed by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, and was circulated to the member bodies in April 1980. It has been approved by the

11、and trailed equipment. 1 Scope and field of application This International Standard specifies the main interchange- ability dimensions for compensator and articulated hydraulic cylinders capable of activating mechanically controlled brakes fixed to the axles of agricultural trailers and trailed equi
12、pment. NOTE - The correct operation of the braking unit requires the presence of one or more recall springs 2 References IS0 1179, Pipe connections for plain end steel and other metal tubes in industrial applications.

13、3 Definitions For the purpose of this International Standard, the following definitions apply. 3.1 compensator cylinder : Cylinder which is rigidly fixed to the chassis of the vehicle by means of a plate or side fasten- ing and the shaft of which has a compensator acting on the brake levers by means
14、 of cables. 3.2 articulated cylinder : Cylinder which rotates about a fixing axis perpendicular to the shaft. 4 Specifications 4.1 Bore or effective diameter of the cylinder The effective diameters of the cylinders shall be as follows : 20 * 0,5 mm 25 k 0,5 mm 30+ 1 mm 36 + 1 mm 4.2 Stroke The strok
15、e shall be not less than 100 mm. 4.3 Coupling port The coupling port shall have a thread G l/4, conforming to IS0 1179, or M 14 x I,5 conforming to IS0 6149. 1 Copyright International Organization for Standardization Provided by IHS under license with ISONot for ResaleNo reproduction or networking p
