Summary of the invention
Problem to be solved in the utility model is to provide a kind of novel electric transport vehicle shock absorption device, and it is produced, and assembling is simple, good damping effect.
Novel electric transport vehicle shock absorption device described in the utility model, comprise drive wheel, guide rail pole and damping spring, it is characterized in that: described drive wheel is provided with central support, the top cylinder of this drive wheel passes the through hole on surface bearing, bearing shim and central support successively, and stretches out central support; Described central support above and below is respectively equipped with fixed block and lower bracket; Fixed block left and right two slide openings are stretched out respectively in two guide rail pole upper ends, and its top is respectively equipped with large pad and fix screw; Two guide rail pole lower ends are passed respectively central support and lower bracket left and right two slide openings successively, and stretch out lower bracket; Two damping springs are enclosed within respectively on two guide rail poles between fixed block and central support.
During application, fixed piece and lower bracket are all fixed on vehicle body rear wall, and drive wheel is up-and-down movement together with central support, and by damping spring effect, vehicle body obtains damping effect.
Further, in fixed piece, central support and lower bracket left and right two slide openings, be equipped with anti-wear sleeve.
Useful technique effect of the present utility model is: owing to connecting the central support of drive wheel, be located between upper fixed block and lower bracket, and only adopt two guide rail pole slip cross-under at upper fixed block, central support and lower bracket the right and left slide opening, and two damping springs are enclosed within respectively on two guide rail poles between fixed block and central support.Therefore it is produced, assembling is simple, good damping effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model application structure schematic diagram.
The specific embodiment
Accompanying drawing mark explanation: upper fixed block 1, guide rail pole 2, damping spring 3, central support 4, lower bracket 5, anti-wear sleeve 6, fix screw (7,12,13), large pad 8, drive wheel 9, surface bearing 10, bearing shim 11, installation through hole 14, vehicle body 15.
As shown in Figure 1, a kind of novel electric transport vehicle shock absorption device described in the utility model, comprise drive wheel 9, guide rail pole 2 and damping spring 3, described drive wheel 9 is provided with central support 4, the top cylinder of this drive wheel passes the through hole that can rotate for drive wheel top cylinder on surface bearing 10, bearing shim 11 and central support 4 successively, and stretches out central support 4; Described central support 4 above and belows are respectively equipped with fixed block 1 and lower bracket 5; Fixed block 1 left and right two slide openings are stretched out respectively in two guide rail pole 2 upper ends, and its top is respectively equipped with large pad 8 and fix screw 7; Two guide rail pole 2 lower ends are passed respectively central support 4 and lower bracket 5 left and right two slide openings successively, and stretch out lower bracket 5; Two damping springs 3 are enclosed within respectively on two guide rail poles 2 between fixed block 1 and central support 4.In the slide opening of fixed piece 1, central support 4 and lower bracket 5 the right and lefts, be equipped with anti-wear sleeve 6.
As shown in Figure 2, when mounted, first upper fixed block 1 and lower bracket 5 are fixedly connected on the rear wall position of vehicle body 15 settings by fix screw 13 respectively, wherein vehicle body 15 rear walls are provided with the corresponding connecting bore of fix screw 13, and fixed block 1 and lower bracket 5 rear sides are provided with the corresponding connecting screw hole of fix screw 13.Then, the top cylinder of drive wheel 9 is passed to the installation through hole 14 in vehicle body 15 bottoms upward, put successively again surface bearing 10, bearing shim 11, by the central support 4 between upper fixed block 1 and lower bracket 5, by three pairs of fix screws 12, through the respective through hole on surface bearing 10, bearing shim 11 limits, be fixedly connected with drive wheel 9, together with drive wheel 9 is fixedly connected with central support 4 like this, and also can rotate around its vertical axis relative to central support 4.
