Detailed description of the invention
The pilot unit construction schematic diagram that Fig. 1 provides for the embodiment of the present invention one, Fig. 2 is used in the schematic top plan view on motor train unit for the pilot assembly shown in Fig. 1, Fig. 3 is the A-A cutaway view of Fig. 2, Fig. 4 is the close-up schematic view of Fig. 3, Fig. 5 to rise later schematic diagram for pilot on the motor train unit shown in Fig. 4, Fig. 6 rotates later schematic diagram for pilot on the motor train unit shown in Fig. 5, and Fig. 7 is the elevational schematic view of Fig. 2, and Fig. 8 is the close-up schematic view of Fig. 7.
See Fig. 1-Fig. 8, the embodiment of the present invention one provides a kind of pilot 1 assembly, wherein, comprise pilot 1 and installing component, installing component comprises fixed parts 2 and movable parts 3, described fixed parts 2 is for being fixed on head car 7 or the trailer of motor train unit, described movable parts 3 is movably arranged on described fixed parts 2, described pilot 1 is fixed on described movable parts 3, wherein, described movable parts 3 can move along the short transverse of motor train unit, and can rotate around the direction being parallel to axle of motor train unit.
Herein, the short transverse of motor train unit is vertical directions, and axletree refers to that often pair of wheel is to upper axletree, and axial direction refers to the axis direction of axletree.
The essence of technique scheme realizes hiding of pilot, that is, make the pilot on a car be in the state of stretching out, to make it possible to clear away the obstacle on track; Make the pilot on trailer be in hidden state, to reduce the resistance that trailer is subject to, thus reduce the resistance of whole motor train unit in operational process.When pilot normally works, between motor train unit base and train rail, when hiding, pilot should be almost complete between motor train unit base and the vehicle body of motor train unit.It should be noted that, the end bottom shape of head car or trailer is not level, but has certain radian herein.But the ground of pilot is then level, realize hiding of pilot, so will apply two power to pilot, one is the power along motor train unit short transverse, within rising to motor train unit boundary line to make pilot from control position; Another is turning effort, to make the bottom of pilot as far as possible parallel with the radian bottom trailer.
The version that movable parts can adopt multi-part to combine, parts realize the rotation of pilot, and another parts realize the lifting of pilot.Hereinafter will introduce the preferred implementation of movable parts in detail.
The pilot assembly that technique scheme provides, due to can pilot be hidden, therefore extra power need not be consumed, take simple structural measure can reduce stream line pattern motor train unit tailstock eddy resistance, thus reduce the overall operation resistance of motor train unit, save the energy.
Preferably, installing component adopts following implementation:
See Fig. 1 and Fig. 3, described fixed parts 2 comprises supporting seat 21, and described supporting seat 21, for being fixed on head car 7 or the trailer of described motor train unit, described supporting seat 21 is provided with chute 22, and described chute 22 is arranged along the short transverse of described motor train unit.Described movable parts 3 comprises slide block 31 and the first turning cylinder 32, described slide block 31 is slidably installed in described chute 22, described first turning cylinder 32 rotates and is arranged on the side of described slide block 31 away from described chute 22, and described pilot 1 is fixed on described first turning cylinder 32 one end away from described slide block 31.
Supporting seat is mainly played a supporting role, and the embodiment of the present invention does not limit its outer shape structure.Chute is preferably straight-line groove, to reduce the resistance in slipping.The mode that is rotationally connected between first turning cylinder and slide block has multiple way of realization, and the present invention is not limited this.The rotational power of the first turning cylinder can come from the motor of peripheral hardware, certainly, also can arrange special drive motor for pilot assembly.
Adopt the installing component of above-mentioned implementation, effectively can realize hiding and stretching out of pilot.

Journal stirrup on pilot two sides (specifically referring to two sides being positioned at axial direction) can design pore-forming, as rectangular opening, then by the feeler lever of same cross-sectional area, as rectangle feeler lever puts in hole, feeler lever and movable parts is fixed, moves and rotate pilot.Journal stirrup can also adopt welded structure to be formed, and is such as directly welded on the two sides of pilot by two pieces of metal thick plates.
After arranging journal stirrup, the movable parts of pilot assembly can more easily be fixed with pilot.
See Fig. 1, Fig. 5 or Fig. 6, further, described pilot 1 is provided with boss 5 away from the end of described head car 7 or trailer, and on described head car 7 or trailer, correspondence is provided with brace table 6, and described brace table 6 is for supporting described boss 5.
Pilot has two ends, and one is positioned at towards headstock or tailstock outermost end, and another is in the middle part of car body, and boss is arranged on that end in the middle part of car body herein.When pilot is in running order, boss is placed on brace table, to make the installation of pilot more firm.
The pilot assembly that technique scheme provides, because pilot can be hidden, in use, low when the eddy resistance of trailer exposes than pilot, reduce the running resistance of motor train unit.
The pilot unit construction schematic diagram that Fig. 9 provides for the embodiment of the present invention two.
The embodiment of the present invention two is with the difference of embodiment one technical scheme, and the specific implementation of installing component is different.
In the present embodiment, see Fig. 9, described fixed parts 2 comprises permanent seat 23; Described movable parts 3 comprises hydraulic ram 33 and the second turning cylinder 34, the telescopic direction of described hydraulic ram 33 is along the short transverse of described motor train unit, described second turning cylinder 34 rotates and is arranged on described permanent seat 23, the cylinder body of described hydraulic ram 33 is fixed on described second turning cylinder 34, and described pilot 1 is fixed on the piston rod of described hydraulic ram 33.
Adopt the installing component of above-mentioned implementation, effectively can realize hiding and stretching out of pilot.
The pilot assembly that technique scheme provides, because pilot can be hidden, in use, low when the eddy resistance of trailer exposes than pilot, reduce the running resistance of motor train unit
The embodiment of the present invention also provides a kind of motor train unit, comprises a car and trailer, wherein, described head car and trailer is provided with the pilot assembly that any embodiment of the present invention provides.
About the detailed introduction of pilot assembly, can see other embodiments.
