Description
Technical field
The utility model relates to a kind of high-grade motor omnibus front air suspension system, relates in particular to the arrangement form of a kind of front air suspension system guiding rod member, the improvement of air bellow undersetting structure, belongs to automotive field.
Background technology
Because vehicle air suspension system is started late in the research and development and the production of China, so motor omnibus of the airsuspension system that China passenger vehicle maker installs now, substantially all be on original leaf spring passenger vehicle production platform, bigger change realizes by original vehicle bridge and vehicle frame (vehicle body) structure are done.The front air suspension system mainly forms by air bellow, height-control valve, shock absorber, guiding mechanism, Panhard rod and with their support etc. that is connected.Present guiding mechanism pattern mainly adopts steel plate guide arm guiding and two kinds of patterns of four-bar linkage guiding.Because steel plate guide arm guiding pattern is intrinsic, the wheel kingpin caster angle constantly changes with operating mode, influences vehicle handling stability, so four-bar linkage guiding pattern becomes current main flow pattern.Four connecting rods guiding pattern mainly has two kinds of layout patterns again: three vertical and one horizontal layout patterns and two longitudinal rods of deriving thereof add the layout pattern of a V-arrangement propelling rod, the defective of these two kinds of layout patterns is: 1, have a longitudinal rod or V-arrangement propelling rod to be arranged in the center of vehicle frame inboard, influence the layout of chassis annex such as air receiver etc., it is very unfavorable that this motorcoach to the band boot compartment is arranged.2, owing to the 1st described reason, must the propons middle upper part install one have the higher-strength requirement in length and breadth to compound fixed bearing of propelling rod or V-arrangement propelling rod fixed bearing, and must change processing or customize special propons again the propons central structure.3, equally by the 1st described reason, must be before central frame beam be installed a longitudinal rod bearing before bearing or two V-arrangement propelling rods of vehicle frame installed inside, therefore not only arrange and cause difficulty, also must rearrange and change or customize again special vehicle frame the body frame structure for automotive and the crossbeam (also needing sometimes) of original maturation to body framwork to brake piping.4, need to be provided with connect bearing behind the air bellow undersetting that is rigidly attached on the propons, shock absorber undersetting, the longitudinal rod, Panhard rod connects bearing etc., exist part many, the complicated problems such as productive costs height, reliability decrease of also bringing thus are installed.5, propons and vehicle frame universalization degree are low, can not effectively utilize existing social resources, make that the suspension system R﹠D cycle is long, cost is high, production efficiency is low.
Summary of the invention
In order to overcome the defective that above-mentioned suspension system exists, first purpose of the present utility model is to provide a kind of later-model front suspension system arrangement form, effectively solve the motor omnibus airsuspension system to original vehicle bridge, vehicle frame (vehicle body) structural modification more greatly and the bigger change of the production technology that causes thus, frock, thereby shorten the research and development of products cycle, raise the efficiency and reduce production costs.
Second purpose of the present utility model is to provide a kind of structural shape of combination type air spring lower support, effectively solves many, the installation complexity of part that present airsuspension system exists, and the problem of the reliability decrease of bringing thus.
The utility model is achieved through the following technical solutions: a kind of motor omnibus front air suspension system: comprise air bellow, shock absorber, Panhard rod, height-control valve and be fixed on suspension systems such as forward thrust rod bearing on the bus frame connecting support and forming, Panhard rod, its front end is connected on the suspension rod upper bracket by its suspension rod, the combination crossbeam is fixed on the bus frame, and it is characterized in that: it also comprises five connecting rod guiding mechanisms and combination type air spring lower support.
Described five connecting rod guiding mechanisms, adopt the arrangement form of four vertical and one horizontal: four longitudinal rods are installed in the vehicle frame outside, its front end is connected with the forward thrust rod bearing, the rear end is connected with the combination type air spring lower support, and four longitudinal rods form two parallelogram sturcutres of symmetry in the vehicle right and left both sides; A lateral rod, its right-hand member is connected with the combination type air spring lower support on right side, and left end is connected with the combination crossbeam, and the forward thrust rod bearing adopts bolt connection mode to be fixed on the bus frame.
Described combination type air spring lower support, its lower end is bolted on the propons by four.Its top is connected with the air bellow below and plays a supporting role, its front side is connected with the lateral stability rod rear end with two longitudinal thrust rod rear ends, but rear side fixed buffer lower end, air bellow, its upper end is connected with the air bellow upper bracket, the air bellow upper bracket adopts bolt connection mode to be fixed on the bus frame.
Described shock absorber, its upper end is connected with the air bellow upper bracket.
Described combination crossbeam, design has on lateral rod and the height-control valve and connects bearing on it, adopts bolt connection mode that crossbeam is fixed on the bus frame.
Described height-control valve, its lower end is connected with the height-control valve lower bracket.
Described height-control valve lower bracket is contained on the propons by 1 " hanging ditch shape " bolt card.
Compared with prior art, this practicality newly has following beneficial effect: 1, simplified the installation of suspension system on vehicle bridge and vehicle frame, the production efficiency of raising car load factory.2, need not do any change to propons, can make full use of existing vehicle bridge social resources, improve social benefit.3, do not change structure, production technology and the frock of former vehicle frame, only need to bore the hold-down bolt hole on request and get final product in the relevant position that four parts such as forward thrust rod bearing, suspension rod upper bracket, air bellow upper bracket, combination crossbeam are installed.4, formed two parallelogram four-bar linkages of symmetry fully in the vehicle right and left both sides by four longitudinal rods, be responsible for longitudinally guiding, laterally steering is finished by lateral rod fully.The advantage that not only keeps existing structure, and a propelling rod ball pivot bearing radial force are not born axial force, in the service life that the energy actv. improves ball pivot, have reduced automotive use and maintenance cost.5, the combination type air spring lower support has replaced a plurality of parts such as former air bellow undersetting, longitudinal rod rear support, bumper undersetting, stabilizer rod bearing, compact conformation, take up room little, simplified assembly technology, cost and reduced, actv. solved part many, complexity is installed and degradation problem under the system reliability that causes.6, can carry out the seriation design to the combination type air spring lower support,,, help improving " the three change levels " of suspension system, reduce the cost of suspension system as tourist coach, private bus, city bus etc. to be applicable to dissimilar motorcoach suspensions.
