The working principle that the combined type for magnetic suspension train that the utility model provides supports pulley oil cylinder is as follows:
1, support pulley oil cylinder and stretch out work (when magnetic suspension train will be stopped)
After the oil inlet hole of oil cylinder passes into the oil pressure of 13.5MPa, promote piston advances forward, piston now overcomes the power of intermediate reset spring, power is delivered on supporting bracket, supporting bracket synchronously travels forward, and the pulley forward contact on supporting bracket front end starts to slide to track, (note, now supporting frame is under the constraint of the anti-rotating shaft in middle part, can not rotate.Pulley can only by former fixing mandrel axis of orientation to high speed rotating.) because the medium of oil cylinder is highly pressurised liquid, the effect reducing to impact and shake can be reached.When train needs to stop, be fixed under often saving train chassis, dozens of supports pulley in jogging process, pulley bottom train and rail contact and the enormous impact produced when crossing track seam, all support the liquid absorption in the oil cylinder in pulley to dozens of, thus reach the effect of damping.2, pulley oil cylinder retrude work when startup optimization (magnetic suspension train want) is supported.
Flow to when control system switches oil pressure, the filler opening of oil cylinder now, oil pressure is release, former high pressure oil discharge of entering, and the Returnning spring now in the middle of oil cylinder ejects, drive supporting frame retrude, pulley disorbit before supporting frame, (now, system has given there is reverse magnetic force bottom train, train and track produce the space specified, train can high speed operation under magnetic suspension state.
The combined type for magnetic suspension train that the utility model provides supports pulley oil cylinder, concrete improve and advantage as follows:
1, piston is integrated with being threaded with supporting bracket
1) original piston and supporting bracket are two parts, and spring compartment cannot be amplified, and spring restoring force can not meet the demands.2) according to requirements, remove movable end cover this part, by piston directly with supporting bracket one end directly with being threaded, then piston and supporting frame are with being threaded to an assembly, can increase spring total length and spring wire diameter like this, improve supporting wheel withdrawal force.
2, when profile is guaranteed constant, improved by piston and supporting bracket
1) make spring add number of total coils, improve the working life of spring; 2) increase supporting bracket internal diameter, spring wire diameter is obtained and increases thus increase reseting elasticity, substantially increase the reaction velocity of supporting wheel withdrawal force and retraction.
3, original and needed for external stability also cap is middle has added a standard piece lock washer.
Originally there is no lock washer, easily loosened.On present increase lock washer product and cap can not loosen, more safe and reliable.
The utility model applies on high-speed magnetic suspension train, and fully meet train under the situation of loss of excitation power, train can steadily slide in orbit, and plays the function of support and movement during maintenance at ordinary times.The every technical parameter proposed, all with clear and definite specific aim.Cover magnetic suspension train bottom support pulley system, the utility model is mounted on the carrier of high speed operation, and the object orbit of corresponding contact is static.Make this carrier slide with stop contact time Shaochong hit and shake.The screw thread of the utility model left part (being top during installation) and and cap and lock washer can be solid and reliable be arranged on bottom magnetic suspension train, designed pulley is by orbit parameter requirement, and each accessory size and design bearing meet train load and life requirements.The size that right part (in bottom during installation) pulley stretches out is by the unsettled parameter designing of magnetic suspension train.
The utility model can use above-mentioned corresponding occasion, and slide to play to reduce as aerial object decline contact and impact and vibrations, the object deceleration contactor that also can apply to two relative movement need reduce impact and vibrations.Concrete advantage is as follows: 1, compact structure, safe and reliable, and organically by oil cylinder and support pulley frame, pulley combination is a product together, improves safety coefficient in its design.2, good damping effect, adopts liquid damping to be best mode.3, start, sensitive.Supporting pulley can stretch out effectively fast when there being signal, playing and sliding and buffer function.When withdrawing from signal, supporting pulley can retract at once, under the effect of magnetic force, produce gap, ensures train energy high speed operation.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
