The specific embodiment
as shown in Figure 1, this bodywork height control system comprises: four hydraulic height adjusting mechanisms 1, the hydraulic tubing 2 that connects each hydraulic height adjusting mechanism 1, the control cock group 3 that connects each hydraulic tubing 2, one end connects control cock group 3, the other end connects the hydraulic power unit 4 of controller 5 by control signal wire 8a, connect four controllers 5 near the height sensor 6 of hydraulic height adjusting mechanism 1 setting by sensor signal lines 7, described controller 5 is connected with 8b with hydraulic power unit 4 and is connected and is connected with the control cock group by control signal wire 8a, this system also comprises the pressure relay 6A that is connected by signal wire (SW) with controller 5 and is connected by hydraulic tubing with control cock group 3.And after increasing pressure relay 6A in system, can reduce or without height sensor.
As shown in Figure 2, described hydraulic height adjusting mechanism 1 comprises the replaceable spring tray 9 that contacts with former car (vehicle itself) coil spring, with the outer cylinder body 10 of replaceable spring tray 9 by being welded to connect, the inner cylinder body 11 that is connected by screw thread with outer cylinder body 10, the annular piston 12 that moves in the cavity that inner cylinder body 11 and outer cylinder body 10 form, and be welded on oil nozzle joint 13 on outer cylinder body 10.
its principle of work is: when bodywork height need to be regulated, hydraulic power unit 4 output high pressure oils, controller 5 output commands are to control cock group 3, controlling corresponding electromagnetic valve makes and needs the hydraulic height of lifting adjusting mechanism 1 and hydraulic power unit 4 to connect, fluid enters hydraulic height adjusting mechanism 1 through electromagnetic valve, fluid enters by inner cylinder body 11, outer cylinder body 10, the oil pocket of annular piston 12 common sealings, annular piston 12 is stretched out with respect to outer cylinder body 10, and with former car spring 17 on the replaceable spring tray 9 of end in contact fixing with outer cylinder body 10, and annular piston 12 contacts and fixes with former car spring pallet 14, on former car spring pallet 14 and former car shock absorber, terminal pad 15 is fixing, and on former car shock absorber, terminal pad 15 is fixed on vehicle frame.So in motion described above, former car spring 17 upper ends are separated and produce relative displacement by hydraulic height adjusting mechanism 1 with vehicle frame, vehicle is by lifting.When vehicle was adjusted to object height, controller 5 was given an order, and controlled corresponding closed electromagnetic valve, stopped oil-filled.After lifting, hydraulic height adjusting mechanism 1 is as Fig. 3.Height of car is rise height h by the amplitude that described system changes.When controller 5 receives the height adjustment instruction, and when by the signal of height sensor 6, judging vehicle body and need to descend.Controller 5 is given an order, and controls corresponding electromagnetic valve off-load, and fluid is through hydraulic tubing 2 hydraulic return power units 4, and the annular piston 12 in hydraulic height adjusting mechanism 1 is retracted, and bodywork height descends.
When hydraulic height adjusting mechanism 1 did not carry out the lifting action, replaceable spring tray 9 contacted with former car spring pallet 14, guaranteed that bodywork height is with remoulded car is not identical.
As shown in Figure 4: it is that spring separates on the suspension of placement form with shock absorber that the utility model can also be applied in suspension form.
Another kind of described easy height mode can also be utilized and increase pressure relay 6A carry out the interior pressure of sensing hydraulic height adjusting mechanism 1, the state of judgement hydraulic height adjusting mechanism 1 in oil circuit: short status or long status.Concrete: when pressure was zero, hydraulic height adjusting mechanism 1 was short status, and this moment, bodywork height was minimum; Greater than vehicle under current load during normal pressure, hydraulic adjuster structure 1 is in the i.e. long status of upper limit when pressure, and namely bodywork height is for the highest.Can reduce in this adjustment mode or without height sensor 6.
Described hydraulic power unit 4 provides high pressure oil as propulsion source oil charging-discharging control cock when working of system.Hydraulic power unit 4 is driven by vehicular power-bottle, by control system, is controlled.Control cock group 3 is that the electromagnetic valve of several 3-position-3-ways forms, and when electromagnetism is in when upper, hydraulic adjuster structure 1 is communicated with high-pressure oil passage, and is oil-filled in mechanism, the vehicle body lifting; When electromagnetic valve is in when the next, the hydraulic adjuster structure is communicated with oil return line, drains the oil in mechanism, and vehicle body descends; When electromagnetic valve was in meta, hydraulic adjuster structure and hydraulic circuit disconnected, and vehicle body keeps present level.Each 3-position-3-way solenoid valve can be controlled separately the height of a suspension, also can control action together through controller and regulate the car load height.Control cock group and hydraulic power unit are together, all to be controlled by the control signal that controller sends, controller is accepted signal that sensor transmits and user's input, identify current body gesture, and the action (lifting or decline or remain unchanged) that should carry out of judgement, and then control each electromagnetic valve.
Described height adjusting system is used the General Construction on existing vehicle in a large number, comprises existing spring tray, spring fitting support etc., and this system can be arranged on various types of manned vehicles easily.
Described hydraulic height adjusting mechanism has a removable spring tray, and this makes this mechanism when being applied to different vehicle, to the comformability raising of difformity spring.Design and tooling cost have been reduced.
Described height mode can also be utilized in oil circuit and to increase pressure relay and carry out the interior pressure of sensing hydraulic height adjusting mechanism, the state of judgement hydraulic height adjusting mechanism: short status or long status.Concrete: when pressure was zero, the hydraulic height adjusting mechanism was short status, and bodywork height is minimum at this moment; Greater than vehicle under current load during normal pressure, the hydraulic adjuster structure is in the i.e. long status of upper limit when pressure, and namely bodywork height is for the highest.
