Description

A kind of full-bearing type electrobus independent front suspension structure
Technical field
The utility model relates to one and relates to full-bearing type passenger vehicle independent front suspension structure, particularly relates to a kind of full-bearing type electrobus independent front suspension structure.
Background technology
Along with a large amount of consumption of non-renewable resources, and the mankind are to the destruction of environment, make the application of the regenerative resource cleaned more and more extensive.Electric energy, can be transformed by a large amount of renewable resources, thus be widely used.Particularly in city, be that the increasing market of the passenger vehicle of power is large with electric energy.
In the electrobus that China uses now, mostly adopt dependent suspended structure, although dependent suspension has, structure is simple, low cost, intensity high, but along with the develop rapidly of electrobus industry, the shortcomings that dependent hangs also embodies, and especially in the safety and traveling comfort of electrobus, there is deficiency.
Utility model content
In order to solve the problem, the utility model provides a kind of full-bearing type electrobus independent front suspension structure, comprising:
Guiding parts, is used for transmitting longitudinal moment, side force and the moment that produces therefrom;
Damping part, in order to the vehicle frame of electrobus of decaying rapidly and the vibration of vehicle body;
Elastomeric element, is used for bearing and transmits normal load, relaxes impact caused when electrobus travels on uneven road;
Described guiding parts, comprises two Top Crossbeams and two lower cross arms than Top Crossbeam length; The left/right both sides of skeleton front end at the bottom of the car of electrobus arrange a Top Crossbeam and a lower cross arm respectively; The Top Crossbeam of described homonymy and one end of lower cross arm are rotated around same pivot pin jointly, and this end is connected with the wheel hub of homonymy on electrobus by alloy attaching parts, and install brake structure on wheel hub;
Described damping part, comprises two bumpers and two coil springs; The left/right both sides of skeleton front end at the bottom of the car of electrobus arrange a bumper and a coil spring respectively; Described coil spring is set on described bumper, and both upper ends are all fixed on the vehicle frame of electrobus, and lower end is then fixed on the lower cross arm of homonymy;
Described elastomeric element, comprises two air bags, is arranged on the upper end of the Top Crossbeam of the left/right both sides of skeleton front end at the bottom of the car of electrobus respectively, and is connected with skeleton at the bottom of the car of electrobus.
Further, in order to extend the service life of this independent front suspension structure, described Top Crossbeam and lower cross arm all adopt high-strength alloy to make.
Further, described brake structure adopts disc type brake structure.After plate disc brake immersion, brake efficiency reduces little, and water stability is good.When exporting braking force and being identical, size and quality are also less, little at the relieved thermal expansion amount of disc thickness, brake clearance can not be affected as drum brake mechanism after being heated, perfect heat-dissipating and maintenance repair work is convenient, plate disc brake represents the development tendency of drg, raising braking force that can be larger and insensitivity.
Further, in order to ensure the safety that Top Crossbeam is connected with electrobus wheel nave with lower cross arm, and reduce its weight, the one-shot forming of described alloy attaching parts, welding gap and being made up of high-strength alloy as far as possible.
The beneficial effects of the utility model are: full-bearing type electrobus independent front suspension structure provided by the utility model, and structure is relatively simple, and quality is light, decreases the impact that vehicle body is subject to, and improves the traction of wheel; Left and right wheels is beated separately, irrelevant mutually, reduces inclination and the vibrations of vehicle body.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only a wherein width of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
Wherein, 1-wheel hub, 2-air bag, 3-Top Crossbeam, 4-bumper, 5-alloy attaching parts, 6-lower cross arm.
Detailed description of the invention
Below in conjunction with accompanying drawing, be clearly and completely described the technical scheme in the utility model, obviously, described embodiment is only preferred embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
As shown in Figure 1, a kind of full-bearing type electrobus independent front suspension structure, comprising:
Guiding parts, is used for transmitting longitudinal moment, side force and the moment that produces therefrom;
Damping part, in order to the vehicle frame of electrobus of decaying rapidly and the vibration of vehicle body;
Elastomeric element, is used for bearing and transmits normal load, relaxes impact caused when electrobus travels on uneven road;
Described guiding parts, comprises and makes two Top Crossbeams 3 and two lower cross arms 6 than Top Crossbeam 3 length by high-strength alloy; The left/right both sides of skeleton front end at the bottom of the car of electrobus arrange a Top Crossbeam 3 and a lower cross arm 6 respectively; The Top Crossbeam 3 of described homonymy and one end of lower cross arm 6 are rotated around same pivot pin jointly, and this end is connected with the wheel hub 1 of homonymy on electrobus by one-shot forming, welding gap and the alloy attaching parts 5 be made up of high-strength alloy, and on wheel hub 1, disc type brake structure is installed;
Described damping part, comprises two bumpers 4 and two coil springs; The left/right both sides of skeleton front end at the bottom of the car of electrobus arrange a bumper 4 and a coil spring respectively; Described coil spring is set on described bumper 4, and both upper ends are all fixed on the vehicle frame of electrobus, and lower end is then fixed on the lower cross arm 6 of homonymy;
Described elastomeric element, comprises two air bags 2, is arranged on the upper end of the Top Crossbeam 3 of the left/right both sides of skeleton front end at the bottom of the car of electrobus respectively, and is connected with skeleton at the bottom of the car of electrobus.
Full-bearing type electrobus independent front suspension structure provided by the utility model, adopt the two cross arm structure of Length discrepancy, when automotive wheel up-and-down movement, Top Crossbeam 3 is less than lower cross arm 6 motion radian, this by make tire top slight inside and outside move, and bottom influences is very little; This structure is conducive to reducing wear on tyres, improves riding comfort and the directional balance of electrobus; During wheel bounce, up/down transverse arm turns around pivot pin and has nothing to do with opposite side wheel; Because Top Crossbeam is short, when beating, wheel plane tilts to strengthen, but wheelspan change is little; Again because the upper end of coil spring, bumper is all fixed on the vehicle frame of electrobus, and lower end is on lower cross arm 6, and during wheel bounce, coil spring and bumper are all compressed, and plays the effect relaxing impact, damping vibrations respectively; And up/down transverse arm adopts high-strength alloy, ensure that long service life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
