Among the figure, sell 2 on back spring front frame 1, the rear shock absorber, rear shock absorber spacer 3, large washer 4, rear leaf spring assembly 5, back clevis bolt 6, rear shock absorber upper bracket 7, frame assembly 8, back spring after poppet 9, back spring cover plate 10, back clevis bolt 11, back spring lower bolster 12, back bump rubber 13, rear shock absorber assembly 14, back axle assembly 15, rear shock absorber lower bracket 16, rear leaf spring pin 17, back spring hanger assembly 18, wedge pin 19, rear shock absorber downside pin 20.
Five, the specific embodiment
Following with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.
The rear suspension frame device of trolley wireless electric public transit vehicle of present embodiment is with reference to figure 1-5, the rear leaf spring assembly is fixed on the spring carrier, the rear shock absorber assembly is located between frame assembly and the rear leaf spring assembly, and the back suspension device setting height(from bottom) is reduced to apart from ground 20-60cm.
Rear leaf spring assembly 5 front ends link to each other with back spring hanger assembly 18 by rear leaf spring pin 17, back spring hanger assembly 18 later leaf spring pin 17 and afterwards spring front frame 1 link to each other, back spring front frame 1 is by rivet link to each other with frame assembly 8 (the B-B cutaway view of seeing Fig. 3).Rear leaf spring assembly 5 rear ends link to each other with back spring after poppet 9 by rear leaf spring pin 17, and back spring after poppet is with rivet link to each other with frame assembly 8 (A that sees Fig. 2 is to view).
Rear leaf spring assembly 5 and back axle assembly 15 connection modes are as follows: the rectangular beam that spring cover plate 10 after the Plane Installation on rear leaf spring assembly 5 middle parts, back clevis bolt 6,11 pass back spring cover plate and rear leaf spring assembly and back axle assembly is by nut tighten together (the C-C cutaway view of seeing Fig. 4).
The rear leaf spring mode of motion is as follows: its front end links to each other with back spring front frame 1 by back spring hanger assembly 18 that can swing, and its rear end is fixedly linked by rear leaf spring pin 17 and back spring after poppet 9.Because rear leaf spring assembly 5 is a lonely line structure, in the time of its up-and-down movement, lonely line elongates or shortens, and the swing of spring hanger assembly 18 has then just in time remedied the motion of rear leaf spring.Because rear leaf spring assembly 5 and back axle assembly 15 are fixed together, so its up-and-down movement has also driven back axle and wheel up-and-down movement together, the rigidity by the rear leaf spring assembly has cushioned vibrations, has increased the traveling comfort of taking.In order to limit upwards beating of rear leaf spring assembly, back bump rubber 13 is installed on the lower plane of vehicle frame channel-section rail (seeing the C-C cutaway view of Fig. 4), its below faces the last plane of back axle rectangular beam, when the rear leaf spring assembly is upwards beated, back bump rubber bumps the last plane of back axle rectangular beam earlier, thereby has limited beating of rear leaf spring assembly.
Rear shock absorber connects as follows: rear shock absorber assembly 14 upper ends and the rear shock absorber upper bracket 7 that is fixed on the vehicle frame link together, lower end bumper downside pin 20 later is fixed together with rear shock absorber lower bracket 16, and rear shock absorber lower bracket 16 is by afterwards clevis bolt 6,11 and back axle assembly and rear leaf spring assembly are fixed together.Its principle of work is as follows: in the time of rear leaf spring assembly up-and-down movement, because rear shock absorber assembly lower end is fixed on the rear leaf spring assembly, so bumper is elongated or presses weak point, because bumper is a damping member, damping is big during stretching, damping is little during compression, thus effective amplitude and frequency that has reduced vibrations.
The rear suspension frame device of trolley wireless electric public transit vehicle of present embodiment has been realized marking time and getting on or off the bus moving, reduce passenger zone floor level, passenger's secondary or one-level behind the power supply assembly, has improved conveying efficiency.
