Description
Invention field
The utility model relates to low bolster-type tractor electronic control air suspension technology, specially refers to a kind of low bolster-type tractor electronic control air suspension system.
Background technology
Getting rid of and hanging transport is universally acknowledged and the advanced Transportation Organization mode that is widely adopted, is the effective means that improves transport and logistic efficiency, to energy-saving and emission-reduction, build a resource-conserving and environment-friendly society significant.Along with developing rapidly and the increase suddenly of highway transportation volume of China's express highway, get rid of and hang transport fast development and become the Main Trends of The Development of freight market.What is called is got rid of extension transport and is referred to that the low bolster-type tractor of employing, as power, connects trailer at the rear portion of tractor truck, lade or freight container on trailer, and thus, realization is quick loads or unloads, thereby has improved conveying efficiency.Because trailer need to be connected with tractor truck or disconnect, i.e. so-called upper extension and de-extension.To being specifically designed to the ailer-towing vehicle that gets rid of of the trailer of carrying a load on the back, be conventionally also referred to as low bolster-type tractor, require its saddle apart from the height on ground between 1080～1110mm, to meet upper extension or de-requirement for height of hanging.Existing tractor truck art of suspension systems adopts steel spring connecting vehicle frame and vehicle bridge and the main parts size as bearing load conventionally, because the compression distance of steel spring is subject to the impact of its load weight, its saddle changes with load apart from floor level, can not keep constant height, spring type suspension is difficult to saddle design height to drop between 1080～1110mm simultaneously.Obviously, it is too high apart from floor level that existing tractor truck art of suspension systems exists saddle, and empty fully loaded saddle can not keep constant apart from floor level, can not meet the problems such as hanging the operating needs of transport trolley to saddle height of getting rid of.
Summary of the invention
In order to solve existing tractor truck art of suspension systems, to exist saddle too high apart from floor level, empty fully loaded saddle can not keep constant apart from floor level, can not meet the problems such as hanging the operating needs of transport trolley to saddle height of getting rid of, the utility model proposes a kind of low bolster-type tractor electronic control air suspension system.The low bolster-type tractor electronic control air suspension of the utility model system comprises vehicle frame, vehicle bridge, air bellow, through beam, guide arm, guide arm support, bumper crossbeam, vibration damper assembly, stabilizer rod assembly, stabilizer rod arm and lateral rod, it is characterized in that, adopt saddle clamp that vehicle bridge is fixed on to guide arm middle part, one end of guide arm is fixed on frame outside by guide arm support, and the other end connects the through beam end of horizontally set; The bottom of air bellow is fixed on top, through beam end, and top is fixed on frame outside by air bag upper cover plate and air-bag support; On the vehicle frame above vehicle bridge, be provided with bumper crossbeam, between bumper crossbeam and vehicle bridge, be provided with vibration damper assembly; Lateral rod is arranged on the vehicle bridge top between vehicle frame and vehicle bridge, and stabilizer rod assembly is arranged on the vehicle bridge bottom between vehicle frame and vehicle bridge; In addition, be also provided with air suspension electric-control system ECAS, comprise electronic control unit ECU, electromagnetic valve, height sensor, line filter and check valve; One end of described highly sensing mechanism is arranged on vehicle bridge top, and the other end is arranged on frame outside; Height sensor is arranged on the vehicle frame of back axle top; Line filter and check valve are arranged in the gas circuit of air suspension; Height sensor and electromagnetic valve are electrically connected with ECU.
The useful technique effect of the low bolster-type tractor electronic control air suspension of the utility model system is to effectively reduce the height of saddle apart from ground, meet to get rid of and hung the requirement of transport trolley to saddle height, can conveniently carry out upper extension and de-extension, thereby improve conveying efficiency.Meanwhile, adopt electronic control air suspension system ECAS perception saddle height, and can saddle height be kept and be regulated, make suspension there is lower natural frequency and good Vehicle Driving Cycle ride comfort.
Brief description of the drawings
Accompanying drawing 1 is the three-dimensional structure schematic diagram of the low bolster-type tractor electronic control air suspension of the utility model system.
Below in conjunction with accompanying drawing and concrete enforcement, the low bolster-type tractor electronic control air suspension of the utility model system is further described.
Detailed description of the invention
Accompanying drawing 1 is the three-dimensional structure schematic diagram of the low bolster-type tractor electronic control air suspension of the utility model system, and in figure, 1 is vehicle frame, 2 is vehicle bridge, and 3 is guide arm, and 4 is guide arm support, 5 is through beam, and 6 is saddle clamp, and 7 is air bellow, 8 is air-bag support, and 9 is bumper crossbeam, and 10 is vibration damper assembly, 11 is highly sensing, and 12 is lateral rod, and 13 is stabilizer rod assembly, 14 is highly sensing mechanism, and 15 is stabilizer rod arm.As seen from the figure, the low bolster-type tractor electronic control air suspension of the utility model system comprises vehicle frame 1, vehicle bridge 2, air bellow 7, through beam 5, guide arm 3, guide arm support 4, bumper crossbeam 9, vibration damper assembly 10, stabilizer rod assembly 13, stabilizer rod arm 15 and lateral rod 12, it is characterized in that, adopt saddle clamp 6 that vehicle bridge 2 is fixed on to guide arm 3 middle parts, one end of guide arm 3 is fixed on vehicle frame 1 outside by guide arm support 4, and the other end connects through beam 5 ends of horizontally set; The bottom of air bellow 7 is fixed on through beam 5 tops, end, and top is fixed on vehicle frame 1 outside by air bag upper cover plate and air-bag support 8; On the vehicle frame above vehicle bridge 2, be provided with bumper crossbeam 9, between bumper crossbeam 9 and vehicle bridge 2, be provided with vibration damper assembly 10; Lateral rod 12 is arranged on vehicle bridge 2 tops between vehicle frame 1 and vehicle bridge 2, and stabilizer rod assembly 13 is arranged on vehicle bridge 2 bottoms between vehicle frame 1 and vehicle bridge 2; In addition, be also provided with air suspension electric-control system ECAS, comprise, electronic control unit ECU, electromagnetic valve, highly sensing mechanism 14, height sensor 11, line filter and check valve; One end of described highly sensing mechanism 14 is arranged on vehicle bridge 2 tops, and the other end is arranged on vehicle frame 1 outside; Height sensor 11 is arranged on the vehicle frame 1 of vehicle bridge 2 tops; Line filter and check valve are arranged in the gas circuit of air suspension; Height sensor 11 and electromagnetic valve are electrically connected with ECU.The low bolster-type tractor electronic control air suspension of the utility model system adopts air bellow connecting vehicle frame and vehicle bridge and the main parts size as bearing load, be provided with highly sensing mechanism and height sensor, and adopt air suspension electric-control system ECAS monitoring saddle height.Therefore, the low bolster-type tractor electronic control air suspension of the utility model system can be carried out Real-Time Monitoring to saddle height, and controls as required the height of air bellow, thereby regulates the height of saddle.The low bolster-type tractor electronic control air suspension of the utility model system is provided with vibration damper assembly between bumper crossbeam and through beam, plays a part rapid damped vibration, improves traveling comfort and the Vehicle Driving Cycle ride comfort of car load.In addition, the low bolster-type tractor electronic control air suspension of the utility model system also upper and lower part between vehicle frame and vehicle bridge is provided with respectively lateral rod and stabilizer rod assembly, can effectively limit the cross travel of back axle, increase the roll rate of suspension, improve the road-holding property of car load.
