The present invention, by the complementary regulatory function of secondary side bearing clearance, ensures there are enough gaps between crossbeam 2 and side bearing apparatus, avoids side bearing apparatus and kill, meet the needs that each operation is shunt.
As shown in Figure 1, the end face at described crossbeam 2 two ends is respectively provided with one group of slide mechanism respectively, described slide mechanism includes: be fixed on slideway on described crossbeam 2 21 and can along the slip blade 11 of described slideway 21 movement, the first described bracing or strutting arrangement 3 and the second bracing or strutting arrangement 20 are fixedly installed on corresponding slip blade 11 respectively.The both sides of described slip blade 11 are respectively arranged with the locating dowel pin 12 for positioning with described slideway 21 after described slip blade 11 moves to the position of setting along described slideway 21.
As Fig. 1, shown in Fig. 4, the first described bracing or strutting arrangement 3 is identical with the second bracing or strutting arrangement 20 structure, include: be fixed on the pillar stiffener 10 on the slip blade 11 of crossbeam 2, be positioned at the prop head 9 for supporting locomotive railway carriage above described pillar stiffener 10, be arranged on the friction plate up and down 13 between described pillar stiffener 10 and prop head 9, described prop head 9, upper and lower friction plate 13 and pillar stiffener 10 are by running through prop head 9 successively, the joint pin 22 of upper and lower friction plate 13 and pillar stiffener 10 is interconnected, wherein, the upper end of described joint pin 22 is fixedly connected with described prop head 9, cell type rectangular rubber spring is provided with in described pillar stiffener 10, the lower end of described joint pin 22 is inserted in described cell type rectangular rubber spring.
As shown in Figure 5, described side bearing apparatus 8 includes side bearing body 14, the both sides of described side bearing body 14 are horizontal is respectively formed with screw penetration hole 23, described side bearing body 14 is fixedly connected with the first described longeron 1 or the second longeron 19 by the screw 17 inserted in described screw penetration hole 23, on the middle part of described side bearing body 14, lower through be formed with adjustment hole 24, the stud 15 be provided with for regulating described crossbeam 2 height run through in described adjustment hole 24, the bottom of described stud 15 is formed with the setting nut 16 for regulating described stud 15 to stretch out described side bearing body 14 upper surface length regulating screw thread 25 and combine with described adjustment screw thread 25.
The motor vehicle power process bogie of adjustable width of the present invention, adopt two vertical and one horizontal three Beam formula structures, by a crossbeam 3 and two longitudinal beams be, first longeron and the second longeron composition, structure is simple, bearing capacity is large, has install matching preferably with driving power (battery pack), actuating device equipment.Frame forms primarily of standard section and Plate Welding, and frame welding standard and intensity meet GB.
Removable II type bracing or strutting arrangement 3,20 and battery pack 4 is installed on crossbeam top; Bottom, chassis install actuating device 6 and driving wheel to 5, flower wheel to 7, crossbeam bottom is provided with the side bearing 8 that two utilize threaded adjusting gap.Process bogie, by self-contained maintenance valve-regulated lead-acid battery group 4, actuating device 6, makes car body possess traction function.
Bracing or strutting arrangement of the present invention (Fig. 1, Fig. 2, Fig. 3, Fig. 4), changes by conventional center tray type structure as both sides cliding friction tray type structure into, makes agent structure become simple and practical.Slip blade is in bracing or strutting arrangement bottom, by the ramps contact in plane on the slip blade of ground finish and crossbeam, and the locating dowel pin manually operated is located on crossbeam, different vehicles realizes by changing bracing or strutting arrangement with relative position that is horizontal, longeron, have 4 control positioies in the direction of the width selective, meet the vehicle-width requirement of CRH1, CRH2, CRH 3, CRH 5 type car respectively, position determine after by locating dowel pin lock in place.
Bracing or strutting arrangement, except completing car body support function, also holds a concurrent post that car body is made a detour, the function of turnout passing and bend.In design, support and connection adopt resilient mounting, install cell type rubber spring in the pillar stiffener of prop head bottom.Static weight and a certain amount of live load of vehicle body upper portion pass to framework through car body prop head, side bearing apparatus, and horizontal, longeron gives each wheel shaft by axle box uniform distribution again.Also friction plate is installed below prop head, the lower friction plate of installation above of bracing or strutting arrangement.Upper friction plate and lower friction plate form sliding friction pair, make the longitudinal direction of prop head relative support device and laterally all have certain slippage, in order to meet the turnout passing of process bogie load condition, to cross the requirement of curve section.
Prop head, when straight path section, is returned to the center of bracing or strutting arrangement by cell type rubber spring, the reset response power that the effect of rubber spring has two: one to be to provide prop head; Two are to provide sliding resistance, reduce serpentine locomotion during car body turnout passing.Meanwhile prop head can deflect certain angle around self axis of revolution, to provide the displacement of the relative angular displacement between bogie truck and car body.
Two adjustable side bearing apparatus are arranged on the bottom of crossbeam, the axial clearance carried between the crossbeam of vehicle and side bearing apparatus can be regulated by the screw-driven of longitudinal stud 15 and nut 16, thus ensure there are enough gaps between each side bearing of vehicle and frame, avoid side bearing to kill, meet the needs that each operation is shunt.
