Abstract

The utility model relates to a combined type air hanger, which comprises a self-steering axle and two sets of road springs, wherein the road springs are connected with a vehicle frame, and are fixed on the self-steering axle through road spring seats. The utility model is characterized in that the combined type air hanger is also provided with an air bag; an upper seat of the air bag is arranged on the upper part of the air bag; a lower seat of the air bag is arranged on the lower part of the air bag; the upper seat of the air bag is connected with the vehicle frame; and the lower seat of theair bag is fixed with the corresponding road spring seats. The utility model can relieve and reduce the vibration force produced by impact caused by ground shake, has the advantages of light weight, low manufacture cost, capability of reducing tyre abrasion, safety, reliability, flexible control, convenient operation and good smoothness. The offset frequency is smaller than 1.5 Hz.

Description

Combination type air hangs
Technical field
The utility model relates to a kind of automobile and hangs with combination type air, specifically, and a kind of exactly automobile hanging shock absorption device that combines by steel spring and air bellow.Belong to automobile and spare parts manufacture technical field thereof.
Background technology
Existing automobile hanging, great majority are BF, and its shortcoming is that own wt is big, and stiffness variation is little, needs the assembling bumper, is not suitable for the operating needs of automobile lightweight development.
Application number is that 018109225 Chinese patent application discloses a kind of integrated fifth-wheel hitch and vehicle bridge suspension assembly, and this assembly comprises: the fifth-wheel hitch chassis; A pair of suspension bracket; And the device that is integrated and connected, its opposite sides on the draw gear chassis is rigidly connected fifth-wheel hitch chassis and suspension bracket.Application number is that 012614319 Chinese utility model patent discloses a kind of multiaxis extra heavy off road vehicle hydro-pneumatic spring equalizing-suspension device, it be provided with on the vehicle bridge hydro-pneumatic spring, hydro-pneumatic spring bearing, down longitudinal rod, lower thrust rod support, on longitudinal rod, lateral rod.Above-mentioned various automobile hanging can not well solve the problem of vibrating and jolting, and influences the ride comfort of car load.
Summary of the invention
At the deficiencies in the prior art, technical problem to be solved in the utility model is, provides a kind of combination type air to hang, and with the vibratory force of alleviating and decay is jolted and caused because of ground that impact was produced, solves the problem of the ride comfort of car load operation.
For solving described technical matters, technical solution adopted in the utility model is, a kind of combination type air hangs, it comprises following steering axle and two additional leaf springs that connect to ground, steel spring is fixed on the following steering axle by spring block, and it also is provided with air bag, and air bag top is provided with the air bag seat of honour, the bottom is provided with following of air bag, the air bag seat of honour connects to ground, and following of air bag and cooresponding spring block are fixed together.
Above-mentioned combination type air hangs, and following of its air bag is captiveed joint with cooresponding spring block by bolt; Its spring block is captiveed joint with following steering axle by spring bolt.
Above-mentioned combination type air hangs, and the front end of its steel spring is connected with the preceding hanger of vehicle frame, and its rear end is connected with turning to hanger, turns to hanger to be connected with the back hanger of vehicle frame.
Combination type air of the present utility model hangs, and the air bellow that is made of air bag and annex thereof and the elastic body of two kinds of different-stiffness of steel spring link into an integrated entity by rigid connector, constitute automobile suspension arrangement jointly.When the vehicle no-load run, the vertical gravity that produces, all bear by steel spring, when vehicle full-load run, air pressure injected becomes air bellow in the air bag, the vertical gravity of this kind state is to be born jointly by steel spring and air bellow, and mainly is to be born by air bellow, and steel spring mainly plays the effect of longitudinally guiding and balance lock torque.
This combination type air hangs, between vehicle frame and axletree, and the vibratory force that impact produced that can alleviate and decay and jolt and cause because of ground, in light weight, cost is low, reduces wear on tyres when unloaded, has reduced oil consumption simultaneously again, reduces atmospheric contamination; And processing and manufacturing is simple, and installing and locating is convenient, and main is safe and reliable, and control is flexible, and easy to operate, the offset frequency value is less than Hz1.5, and ride comfort is good, improves the service life of hanging.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation that the utility model combination type air hangs;
Fig. 2 is the right elevation of structure shown in Figure 1.
The specific embodiment
As shown in Figure 1, a kind of combination type air hangs, it comprises following steering axle 1 and two additional leaf springs 13 that connect to ground, steel spring 13 is fixed on the following steering axle 1 by spring block 2, the front end of steel spring 13 is connected with the preceding hanger 10 of vehicle frame, its rear end is connected with turning to hanger 16, turns to hanger 16 to be connected with the back hanger 11 of vehicle frame.Also be provided with air bag 12 between the spring block 2 of steel spring 13 and vehicle frame, air bag 12 tops are provided with the air bag seat of honour 5, the bottom is provided with following 4 in air bag, and the air bag seat of honour 5 connects to ground, and following 4 in air bag is fixed together by bolt 3 and cooresponding spring block 2; Spring block 2 is captiveed joint with following steering axle 1 by spring bolt 15.
This combination type air hangs, and between vehicle frame and axletree, the air bellow that is made of air bag and annex thereof and the elastic body of two kinds of different-stiffness of steel spring link into an integrated entity by rigid connector, constitute automobile suspension arrangement jointly.When the vehicle no-load run, the vertical gravity that produces, all bear by steel spring, when vehicle full-load run, air pressure injected becomes air bellow in the air bag, the vertical gravity of this kind state is to be born jointly by steel spring and air bellow, and mainly is to be born by air bellow, and steel spring mainly plays the effect of longitudinally guiding and balance lock torque.This combination type air hangs the vibratory force that impact produced that can alleviate and decay and jolt and cause because of ground.
