Embodiment
The utility model is made up of piston assembly 1, the first support ring 2, the first one-way valve 3, spacer assemblies 4, the second support ring 5, the second one-way valve 6, cylinder barrel 7, three-support ring 8, black box 9, bar cylinder 10, pressing plate 11, main oil pocket 12, drying nitrogen 13, the first damping hole 14, the first damping oil pocket 15, the second damping oil pocket 16, the second damping hole 17, as shown in Figure 1.Wherein, piston assembly 1, the first support ring 2, the first one-way valve 3, cylinder barrel 7, three-support ring 8, black box 9, bar cylinder 10, pressing plate 11, the first damping hole 14, the first damping oil pocket 15, main oil pocket 12 and piston 21, support ring 22, one-way valve 23, bar cylinder 24 in Fig. 2, support 25, black box 26, bar cylinder 27, pressing plate 28, drying nitrogen 29, damping hole 30, damping oil pocket 31, main oil pocket 32 be corresponding identical, main oil pocket 12 inside are filled with hydraulic oil and drying nitrogen 13.Different one is to set up the second damping oil pocket 16 between described the first damping oil pocket 15 and bar cylinder 10, and this second damping oil pocket 16 is provided with the second damping hole 17 and the second one-way valve 6, forms many damping cavity structure, promotes the effectiveness in vibration suppression hanging.Different two is to be provided with the second support ring 5 and spacer assemblies 4 on the cylinder barrel 7 that connection part is corresponding between the first damping oil pocket 15 and the second damping oil pocket 16.Bar cylinder 10 bottoms are fixedly connected with the front wheel spindle of quarry tipper by the conical surface and pressing plate 11, cylinder barrel 7 is fixedly connected with carriage of mining self-unloading vehicle by bolt and flat key, vehicle runs into uneven road surface and produces while jolting, wheel is beated with respect to vehicle frame, cause that relative movement occurs for suspension arrangement cylinder barrel 7 and bar cylinder 10, thereby make the front-end equipment interior nitrogen expansion of main oil pocket 12 or compression, the first damping oil pocket 15, the second damping oil pocket 16 volumes change, hydraulic oil in chamber first one-way valve 3 of flowing through, the second one-way valve 6 and the first damping hole 14, the second damping hole 17, produce damping, decay Vehicular vibration.
Detailed process is as described below:
1. while running into bump, wheel is upwards beated, driven rod cylinder 10 and piston assembly 1 move upward, nitrogen volume compression in cylinder, in-cylinder pressure rises, cause that the first damping oil pocket 15 volumes increase, the hydraulic oil in main oil pocket 12 is by the first damping hole 14 and the first one-way valve 3(open mode) enter the first damping oil pocket 15; Simultaneously the second damping oil pocket 16 volumes reduce, and the hydraulic pressure in the second damping oil pocket 16 is by the second one-way valve 6(open mode) and the second damping hole 17 enter main oil pocket 12.
2. while running into pothole, bar cylinder 10 and piston assembly 1 move downward under the promotion of cylinder inner high voltage nitrogen, band motor car wheel moves downward and guarantees the normal ground connection of tire, cause that the first damping oil pocket 15 volumes reduce, now the first one-way valve 3 is closed, and the hydraulic oil in the first damping oil pocket 15 flows to main oil pocket 12 by the first damping hole 14; The second damping oil pocket 16 volumes increase simultaneously, and now the second one-way valve 6 is closed, and the hydraulic oil in main oil pocket 12 enters the second damping oil pocket 16 by the second damping hole 17.
In order to produce good damping, prevent the too high pressure of the interior generation of the second damping oil pocket 16 simultaneously, black box 9 is caused to adverse effect, the first damping oil pocket 15 is designed relatively littlely with first damping hole 14 communicating of main oil pocket 12, now can obtain good damping, due to this oil pocket and not UNICOM of black box 9, in oil pocket, producing high pressure also can not have a negative impact to black box 9, can only determine damping hole and one-way valve according to the needs of damping property, make front-end equipment obtain good damping property.
In order to prevent the interior generation partial high pressure of the second damping oil pocket 16, black box 9 is had a negative impact, the second damping hole 17 is designed littlely, it is very large that the second one-way valve 6 designs, in the time running into bump, the second one-way valve 6 is in open mode, and now the second damping oil pocket 16 is more or less the same with main oil pocket 12 internal pressures; In the time running into pothole, the second one-way valve 6 is closed, and only has the second damping hole 17 and main oil pocket 12 UNICOMs, and damping cavity internal pressure can be far below main oil pocket.
Front-end equipment is in the time of compression, and the first one-way valve 3, the second one-way valve 6 are opened back, and damping is relatively little, be conducive to absorb the impact on road surface, in the time of resilience, the first one-way valve 3, the second one-way valve 6 are closed, and produce good damping, attenuation vibration amplitude, reaches good effectiveness in vibration suppression fast.
