Abstract
The utility model relates to a dual-leaf spring rod air suspension structure of a heavy truck drive axle, comprising a suspension guide mechanism, air springs, shock absorbers and joists, wherein the suspension guide mechanism is composed of a V-shaped thrust rod and a transverse stable thrust rod; the transverse stable thrust rod is composed of a cross rod and left and right vertical plates connected to the two ends of the cross rod; one end of each vertical plate is connected to the cross rod, while the other end thereof is connected to a frame support; the two ends of the cross rod are connected to the joists at the inner sides of the vertical plates; two air springs are fixed to the ends of two joists located at the front part of the axle respectively; and two shock absorbers are fixed between the ends of the two joists, located at the rear part of the axle and the frame, respectively. The dual-leaf spring rod air suspension structure of the heavy truck drive axle is characterized in that: the thrust rod and the stable rod structure are combined; the transverse stable thrust rod is capable of bearing the actions of the transverse stable rod and the thrust rod respectively; and simultaneously, the two air springs are arranged in front of the axle so that the suspension is simple and compact in structure; as a result, the mounting adaptability of the suspension is improved and the production cost and the after-sales cost are directly reduced.
Description
Technical field
The utility model relates to a kind of heavy card drive axle air suspension structure.
Background technology
Existing heavily block drive axle air suspension structure and mainly form by parts such as guiding mechanism (V-arrangement propelling rod and longitudinal rod), air bellow, Panhard rod, stabilizer rod suspension rod, shock absorber, joists.Shown in accompanying drawing 1, propelling rod and Panhard rod and suspension rod are separately to make, and the Panhard rod structure also has parts such as suspension rod.In addition, have now and heavily block the arrangement that drive axle air suspension structure generally adopts the joist four gasbags, the load of being born on the spring is bigger, and the stationarity of vehicle is bad.From the installation and maintenance aspects of vehicle, existing block heavily that drive axle air suspension constructional delails is numerous, complex structure, take up room big, production and later maintenance cost be high.
The utility model content
The utility model provides a kind of heavy card drive axle two-man act sheet bar air suspension structure, and it is complicated to solve the existing drive axle air suspension architecture of heavily blocking, and the production maintenance cost is high, the bad technical matters of vehicle stability.
The utility model solves the technical scheme that its technical matters adopted:
This heavy card drive axle two-man act sheet bar air suspension structure; Comprise suspension guide mechanism, air bellow, bumper and joist; Said suspension guide mechanism is to be made up of V-arrangement propelling rod and lateral stability propelling rod, the lateral stability propelling rod by cross bar and be connected in the cross bar two ends about two risers constitute, riser one end is connected with cross bar; The other end is connected with frame brackets, and the cross bar two ends are connected with joist in the riser inboard;
Said air bellow and bumper respectively have two, and two air bellows are individually fixed in two joists and are positioned at the anterior end of vehicle bridge, and two bumpers are individually fixed in two joists between an end and vehicle frame at vehicle bridge rear portion.
The said riser other end is connected with frame brackets by rubber bush.
Said cross bar two ends are with circular lining in the riser inboard, the anulated connection of circular lining and joist set inside.
The beneficial effect of the utility model is following:
The utility model has merged propelling rod and stabilizer rod structure, and the lateral stability propelling rod can be born the effect of Panhard rod and propelling rod respectively.Lateral stability propelling rod and V-arrangement propelling rod can be formed parallel-crank mechanism, control vehicle bridge path of motion, thus obtain less vehicle bridge elevation angle variation and less wheelbase variation.Adopt the lateral stability propelling rod can make the suspension frame structure compact, reduce space hold, improved the installation comformability of this type of suspension; Part reduces relatively, has directly reduced productive costs and expense after sale, makes this type of suspension have more the market competitiveness.
In addition; The utility model also adopts the mode before two air bellows are arranged in vehicle bridge, in conjunction with joist and shock absorber, has utilized the moment balance in the vehicle movement process cleverly; Promptly reduced number of components and parts; Reduced the load of being born on the spring again, simple and compact for structure, improved the installation comformability; Part has reduced, and has directly reduced productive costs and expense after sale; Stability Analysis of Structures, frequency ratio leaf spring suspension is much lower, and the ride comfort of vehicle, traveling comfort are well more a lot of than leaf spring suspension, adapt in the transportation of modern heavy card the requirements at the higher level for goods.
