19、ents 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 to ensure interchangeability of vehicles and implements. The minimum requirements on t

20、he 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 does not deal with airport equipment. This standard does not cover applications, whe

21、re 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.

A clu

25、tch 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 circuits. The hydraulic system consists in either one variable displacement pump or one or two constant pumps.

26、 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 - one switching device for unpressurized circulation. Each circuit or both circuits together shall be equ

27、ipped 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 ensured by the use of quick couplings, refer to 3.1.10. 3.1.4 Flow Rates Nominal Flow Rate circuit No. 1: min

For roa

31、d 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 installed. The cooling capacity shall be verified with a test, which is described in the following. While executing the hydrau

32、lic 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. with an ambient air temperature of 30 C, the hydraulic oil temperature in the oil tank must not exceed 80 C. An adjustable r

33、estrictor 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 equivalent to 5 alternatively 25 % of the minimum continuous power at 75 % of the rated engine speed. During the test, a temperature

34、 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 the outlet of the oil tank. For testing the system, the fans of the hydraulic oil cooler if installed - need to be engaged. Te

P = Q x p (1) where P is the power according to the minimum continuous power (see section 3.1.6); Q is the volume flow of circuit 2 at 75% of the rated engine speed (max. volume flow w

EXAMPLE for calculating the p for the test, which has to be adjusted at the flow restrictor: GVW of the truck e.g. 19 t P min= 20 kW (3.1.6) Rated engine speed e.g. 2 200 min-1 75 % of rated engine speed = 1 650 min-1 Cooling capacity 5 % (winter maintenance vehicle) 5 % of 20 kW = 1 kW Cooling

39、 capacity 25 % (road service area maintenance vehicle) 25 % of 20 kW = 5 kW Calculation of the pressure at the flow restrictor: p = P/Q E.g. Q = 45 l/min, P = 1kW p = 13,33 bar E.g. Q = 45 l/min, P = 5kW p = 66,67 bar With this value of p, the test has to be executed. 3.1.9 Line cross sections Circu
