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 present embodiment front suspension apparatus comprises front spring spring assembly, spring carrier, vibration damper assembly, front stabilizer bar assembly with reference to figure 1-6, reduces to 20-60cm apart from the floor mounted height.
Front spring spring assembly 2 front ends link to each other with preceding spring front frame 1 by front spring spring pin 15, and preceding spring front frame is with rivet link to each other with frame assembly 13 (seeing that C-C analyses and observe among Fig. 4).Front spring spring assembly 2 rear ends link to each other with preceding spring hanger assembly 17 by front spring spring pin 15, before spring hanger assembly 17 link to each other with preceding spring after poppet 14 by front spring spring pin 15, preceding spring after poppet 14 is by rivet link to each other with frame assembly 13 (seeing that B-B analyses and observe among Fig. 3).Front spring spring assembly 2 and front axle assy 23 connection modes are as follows: spring cover plate 9 before the Plane Installation on front spring spring assembly 2 middle parts, the H-girder of spring cover plate and front spring spring assembly and front axle assy was by nut tighten together (seeing that D-D analyses and observe among Fig. 5) before preceding clevis bolt 10 passed.Front spring spring mode of motion is as follows: its front end is fixedly linked by front spring spring pin and preceding spring front frame, and the rear end links to each other with preceding spring after poppet by preceding spring hanger assembly that can swing.Because the front spring spring assembly is a lonely line structure, in the time of its up-and-down movement, lonely line elongates or shortens, and the swing of preceding spring hanger assembly has just in time remedied the front spring movement of springs.Because front spring spring assembly and front axle assy are fixed together, so its up-and-down movement has also driven propons and wheel up-and-down movement together, the rigidity by the front spring spring assembly has cushioned vibrations, has increased the traveling comfort of taking.In order to limit upwards beating of front spring spring assembly, preceding bump rubber 20 is stuck in the preceding spring cover plate 9 (seeing that D-D analyses and observe among Fig. 5), bump rubber hits frame 11 and captives joint with frame assembly 13 by rivet before directly over it, when current steel plate spring assembly is upwards beated, bump rubber hit frame before preceding bump rubber bumped earlier, thereby had limited beating of front spring spring assembly.
Front shock absorber connects as follows: front shock absorber assembly 16 upper ends and the front shock absorber support 12 that is fixed on the vehicle frame link together, and the lower end can cross front shock absorber downside pin 18 and the last a slice of front spring spring assembly is fixed together.Its principle of work is as follows: in the time of current steel plate spring assembly up-and-down movement, because front shock absorber assembly lower end is fixed on the front spring 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.
It is as follows that front stabilizer bar connects: front stabilizer bar assembly 8 rear ends are by front stabilizer bar downside pin 21, stabilizer rod cushion block 21 and the last a slice of front spring spring assembly be fixed together (seeing that E is to view among Fig. 6); Front end is connected on the vehicle frame with packing ring 4 with cushion 3, electrical motor by stabilizer bar bushing 5, stabilizer rod suspension bracket 7, stabilizer rod pivot shaft 6, electrical motor.Its principle of work is as follows: when vehicle right and left turned to, because of vehicle body and vehicle frame are fixedly connected, vehicle body can deflect, and stabilizer rod is equivalent to a torsion bar spring, thereby alleviates the vehicle body amplitude of fluctuation.
The front suspension rack device of trackless wireless electric bus 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.
