21、 to power systems equipped for the operation and able to drive implements and attachments such as snow ploughs and/or spreaders on winter service vehicles or mowers on road service area maintenance vehicles, equipped with front-mounting plates according to EN 15432. The purpose of this standard is t

22、o ensure interchangeability of vehicles and implements. The minimum requirements on the performance and the components of the hydraulic system as well as the kind, the size and the location of the connecting elements between the vehicle and the implement are specified in this standard. This standard

23、 does not deal with airport equipment. This standard does not cover applications, where the implements need a continuous hydraulic oil flow exceeding 45 l/min. 2 Normative references The following referenced documents are indispensable for the application of this document.

27、 pump shall be driven directly by the vehicle engine and independently from the vehicle drive train. A clutch or a coupling between the engine and the pump is permissible. A drive ratio between the engine and the pump is allowed. 3.1.2 Hydraulic Circuits The hydraulic circuits must be open type circ

If there are two circuits, they shall provide flowrate and pressure independent at any working condition. For each circuit there shall exist: - one primary excess pressure protection device and

29、 - one switching device for unpressurized circulation. Each circuit or both circuits together shall be equipped with an oil reservoir and a filter for protection of the hydraulic system. 3.1.3 Connection between the hydraulic system of the vehicle and the implements Hydraulic connectors shall be ens

33、ulic system for winter maintenance vehicles shall be at least 5 % of the minimum continuous power (see section 3.1.6). For road service area maintenance vehicles including summer operation the cooling capacity shall be at least 25 % of the minimum continuous power. If required, an oil cooler can be

34、installed. The cooling capacity shall be verified with a test, which is described in the following. While executing the hydraulic system test in the hydraulic circuit 2, the difference between the hydraulic oil temperature in the oil tank and the ambient air temperature must not exceed T = 50 K, i.e

35、. with an ambient air temperature of 30 C, the hydraulic oil temperature in the oil tank must not exceed 80 C. An adjustable restrictor for simulating the power loss shall be connected to the couplings of circuit 2. The restrictor should be adjusted to a value p, that gives a power absorption equiva

During the test, a temperature difference between the hydraulic oil temperature in the oil tank and the ambient air temperature of T = 50 K must not be exceeded. The oil temperature has to be measured at

37、the outlet of the oil tank. For testing the system, the fans of the hydraulic oil cooler if installed - need to be engaged. Test condition: ambient air temperature 25 C 10 C.
