Air Suspension空气悬架G.LeiberichIntegrated DynamicsEGP = Engineering Grade Plastic 工程塑料 Advantages 优点With cross restriction to stop the vehicle becoming unstable when cornering 通过横向限流使车辆转弯时更稳定 Quick exhaust (depend to version) 快放功能（取决于变型） Height limitation (depend to version) 高度限制功能（取决于变型） 3/2 way valve for quick exhaust e.g. on ferries operation (depend to version) 用于快放的3/2阀，如轮渡操作（取决于变型） 2 nd ride height (depend to version) e.g. on lift axles, for different saddle heights, as „kneeling“ on busses 第二行使高度（取决于变型），如在提升桥上， 用于不同鞍座高度，客车的侧跪系统 Flow rate170 l/min up to 620 l/min (depend to version) 流量从170l/min到620l/min(取决于变型）G.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticThis valve is used for levelling purposes in air suspension systems. Variations in the height of the chassis resulting from load variations are equalized by inflating or deflating the air suspension bellows in proportion to the respective loads carried by the vehicle. For increasing the stability in curves there is the possibility to get this valves with a cross restriction between the both delivery ports. For vehicles with a raise/lower valve it is possible to install a levelling valve with a height limitation device. If the chassis will be raised by using the raise/lower valve the height limitation device will cut the pressure for the port No. 1 of the raise/lower valve when the maximum height of the chassis is reached, so that the chassis cannot be raised anymore. 高度阀的作用是用于空气悬架系统中高度控制．根据车辆的载重情况，通过向空气悬架气囊充气和放气，来控制 车辆底盘的高度．为了增加转弯时的稳定性，高度阀两出气口之间可有横向限流作用． 对于具有底盘提升阀的车辆来说，可安装带高度限制装置的高度阀．底盘通过提升阀提升高度时，如果底盘高度 达到最大时，高度限制装置会切断提升阀１号口的气压，底盘不能再升高.G.LeiberichIntegrated DynamicsEGP = Engineering Grade Plastic工程塑料COLAS ®底盘升降阀EGP®高度阀ILAS ®-E车桥提升阀EB+ISO 7638ISO 1185G.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticVersions 变型612 035 011 DN = 1.25 mm, Linkage losely enclosed, M12 x 1.5 (replacement 612 017 061) 包括控制杆,散装,接口尺寸M12×1.5 612 035 021 DN = 3.00 mm, Linkage losely enclosed, M12 x 1.5 (replacement 612 017 091) 612 035 031 DN = 4.00 mm, Linkage losely enclosed, M12 x 1.5 (replacement 612 017 111) 612 035 001 DN = 3.00 mm, without Linkage, 1/4“ - 18 NPTF不包括控制杆,接口尺寸1/4“ - 18 NPTF(replacement 612 023 251) (replacement 612 023 211612 035 011 DN = 1.25 mm, without Linkage, 1/4“ - 18 NPTF More versions on request 可根据需要提供更多变型G.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticTechnical data 技术参数-Operating pressure, dyn.: pe max. 13 bar工作压力-Perm.dyn. bellow pressure: pe max. 20 bar允许气囊压力-Operating temperature:工作温度- 45°C to + 85°C- Operating range (charging and exhausting):工作范围（充气和放气） 控制位置 关闭区(非调整区) 左边和右边45°-Side of control: on the left and on the right -Dead angle at pe = 7 - 8 bar: 2°G.LeiberichIntegrated DynamicsLevelling valve with height limitation and 2nd ride height具有高度控制和第二高度的高度阀G.LeiberichIntegrated DynamicsLevelling valve with height limitation带高度控制的高度阀Lift axle valve 提升桥阀 ReservoirLift bellow 提升气囊Raise/lower valve 底盘升降阀Ride height 行驶高度G.LeiberichIntegrated DynamicsLevelling valve with height limitation & 2d ride height带高度控制和第二高度的高度阀Reservoir Lift axle valveLift bellowRaise/lower valveRide heightG.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticLevelling valve with 2nd ride height on lift axles具有第二高度的高度阀用于提升桥No addition positioning cylinder and fittings necessary不需其它位置控制缸和接头1st ride height2nd ride heightLow Clearance height 离地间隙较小Enough clearance height, lifted wheel cannot touch the ground 足够离地高度，提升桥不会碰地面第二行驶 高度G.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticLevelling valve with 2nd ride height具有第二高度的高度阀Lift axle valveReservoirLift bellowRaise/lower valveChassis raised, axle down 底盘升起,车桥降下G.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticLevelling valve with 2nd ride height for matching of different saddle heights具有第二高度的高度阀用于不同的鞍座高度No addition positioning cylinder and fittings necessary不需其它位置控制缸和接头1st saddle height2nd saddle heightG.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticLevelling valve with 2nd ride height for matching of different saddle heights具有第二高度的高度阀用于不同的鞍座高度G.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticLevelling valve with 2nd ride height for „kneeling“ at busses具有第二高度的高度阀用于客车侧跪系统 One side or both sided lowering一边或两边降低To match different kerb heights适用不同站台高度For convenient boarding方便上下车Wheel chair friendly方便轮椅上下Drive2nd ride heightSide kneelingPerambulator friendlyG.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticLevelling valve with quick exhaust带快放功能的高度阀Lift axle valveReservoirLift bellowRaise/lower valveLift axle upG.LeiberichIntegrated DynamicsWith ILAS®III it is possible to control a lift axle with a integrated small unit.通过ILAS III可实现以一小集成单元控制提升桥Features: push in fittings for plastic tube integrated damping volume (100 cm³) test connection. 特点：快插接头，与放气(100 cm³) 测试接头集成在一起的快插接头，适合尼龙管 Functions: hand operated or load depending (adjustable) lifting of the axle load depending lowering of the axle (adjustable)功能：手操纵或根据载荷提升或降低桥的高度（可调）1 23 22 21 11G.LeiberichIntegrated DynamicsConventional System 常见的系统1 = 3/2-Way-valve3/2-way 阀2 = Restrictor节流阀1 4 2 3 1 53 = Damping reservoir减震储气筒4 = Pilot valve伺服阀5 = Operating valve操纵阀G.LeiberichIntegrated DynamicsSystemOnly 1 component只需一个零件ILASG.LeiberichIntegrated DynamicsTechnical data 技术数据- Operating pressure: 工作气压 Operating temperature: 工作温度 - 352 049 ... - 352 047/051 ... pe = 8.5 bar - 40° up to + 80° C M 12x1.5 push-in fittings for plastic tube 8x1 快接插头用于尼龙管8x1G.LeiberichIntegrated DynamicsVersions 变型- 352 047 ...

Additional possible features: Dead man function: To raise or lower the chassis it is necessary that the operator holds the handle in the position raise or lower. If he puts his hand away COLAS® switches to "stop" position. This prevents before accidents. Reset to ride height: If the operator ® forgets after loading or unloading to bring the handle of COLAS to the "ride height" position and the vehicle is moving faster then 15 kph the Haldex-ABS with reset to ride ® height possibility (e.g. MODULAR) signals a solenoid valve connected to COLAS and the vehicle automatically comes to the correct driving height.®G.LeiberichIntegrated Dynamics通过 COLAS 可以很方便地升高或降低底盘到相应的高度,接合或甩掉挂车. 其它特点：自动停止功能： 当升高或降低底盘时，需要操作员握住手柄将其推到上升 ® 或下降位置．如果操作员将手移开，COLAS 就切换到“停止”位置，以避免事故的发生. ® 恢复到行驶高度：装货或者卸货后操作员忘记将COLAS 把手放到行车高度位置，当车 ® 辆速度超过15公里/小时后,带恢复行驶高度功能的Haldex-ABS将发送信号到COLAS 上的电 磁阀，车辆高度将自动调整到行驶高度．®G.LeiberichIntegrated DynamicsEGP = Engineering Grade PlasticCOLAS ®EGP® ILAS ®-EEB+ISO 7638ISO 1185G.LeiberichIntegrated DynamicsFunction: 功能Drive 行驶11 1 212212Haldex ABSG.LeiberichIntegrated Dynamics111222112Haldex ABSFunction:功能Raise/ Lower升／降Integrated DynamicsIntegrated DynamicsTODDGNB -Signal COLAS 338 051/054 ...Blind ECU -Haldex Modal ABSWiring 线束Integrated DynamicsTechnical data 技术参数-Operating pressure:p e = 8.5 bar工作气压-Operating temperature:-40°C to + 80°C工作温度范围-Solenoid valve (only 338 051/054...)Permissible duty:10seconds电磁阀允许工作时间-Voltage:UB = 24 VDC + 2.5 -3.5电压-Current / power:lo = 250 mA / Po = 6W电流/功率-Type of protection:DIN40050-IP 65 A保护类型Integrated Dynamics Versions (变型):-338 051 001/002 With dead man function; with RtR (electric); 8 mm push in带自动停止功能;带滚装(滚上/下)(电控); 8 mm 插头-338 051 011/012 With dead man function; with RtR (electric); 8 mm push in -338 052 001/002 With dead man function; without RtR; 8 mm push in -338 053 001/002 Without dead man function; without RtR; 8 mm push in -338 054 001/002 With dead man function; with RtR (electric); 10 mm push in -338 055 001/002 With dead man function;with RtR (pneumatic); 8 mm push in -338 056 001/002 With dead man function; without RtR; 10 mm push inAll versions can replace 338 007/020/021/022/035/036/048 ...。
