Abstract
Disclosed is a double bellow type composite air suspension with two air springs of a driving axle, mainly comprising an elastic element and a guiding mechanism, both of which are connected between vertical beams of two frames and the driving axle. The elastic element is two double bellow type air springs. The upper end of the elastic element is connected with the lower part of the corresponding vertical beam of the frame, and the lower end of the elastic element is supported on a base of the air spring. The guiding mechanism is arranged between the base of the air spring and the driving axle under the base of the air spring. The guiding mechanism is a cambered spring placed vertically, the front end of which is fixed and hinged with a fixing support of the vertical beam of the frame, and the back end of the cambered spring is hinged with the lower end of a swinging arm. The upper end of the swing arm is fixed and hinged with a support of the swing arm of the vertical beam of the frame. The driving axle is placed on a supporting plate, which is connected with a base of the air spring by a bolt. The front end of the supporting plate is connected with the back end of a stock stabilizer, the front end of which is connected with the lower end of a hanging rod. The upper end of the hanging rod is connected with the vertical beam of the frame. With a simple structure and lower cost, the utility model can assure the passenger car to run very smoothly and to be operated steadily.
Description
(1) technical field
The utility model relates to a kind of automobile-used draft hitch, particularly a kind of back suspension device.
(2) background technology
Back suspension device places between vehicle frame and the drive axle, mainly comprises the elastic element and the guiding mechanism that are connected between chassis side rail and the drive axle.Be used for supporting frame, transmit various power and moment between road surface and vehicle frame, alleviate and absorb impact and vibrations when travelling.The guiding mechanism of tradition back suspension device is generally leaf spring, and elastic element generally adopts diaphragm type air spring, the cost height, and suspension arrangement is difficulty relatively.Wherein a kind of common back suspension device, diaphragm type air spring generally is arranged in the leaf spring rear end, and this because the transmission shaft variable angle is bigger, easily produces vibrating noise during wheel bounce concerning rear-mounted engine.Another kind of common back suspension device is four gas spring rear suspension structures, the characteristics of its structure are that the back axle both sides respectively have two membrane type gas springs to be arranged in the drive axle below, and be positioned at the vehicle frame inboard, the semiellipse steel spring waits sheet to form by two, steel spring is also born the elastic element effect of having held concurrently of part vertical load except playing the guiding mechanism effect.For arranging the gas spring, the back axle compressed air brake cylinder must be done corresponding change, needs special back axle, and in addition, because the gas spring is arranged in the vehicle frame inboard, the resisting side-tipping of automobile performance is bad.The traditional suspension structure is owing to coupling, the gas spring pattern of layout pattern, elastic element are selected aspect reasons such as improper for use, and relatively difficulty, vehicle handling stability and ride comfort can not fully satisfy the shortcoming of passenger vehicle operating needs to have complex structure, productive costs height, suspension arrangement.
(3) utility model content
The purpose of this utility model provides a kind of drive axle double curve sac type two gas spring composite air suspensions, solves traditional vehicle suspension frame structure complexity, the productive costs height, and vehicle handling stability and ride comfort can not fully satisfy the technical matters of passenger vehicle operating needs.
The technical solution of the utility model:
This drive axle double curve sac type two gas spring composite air suspensions, mainly comprise the elastic element and the guiding mechanism that are connected between two chassis side raiies and the drive axle, it is characterized in that: above-mentioned elastic element is two double-convolution bellows type air springs, the upper end of each double-convolution bellows type air spring be connected in corresponding chassis side rail below, and be positioned at above the drive axle, the lower end of double-convolution bellows type air spring is bearing on the gas spring base, be equipped with guiding mechanism between gas spring base and the drive axle below it, this guiding mechanism is vertical semiellipse steel spring of putting, the front end of this semiellipse steel spring is hinged with the fixed bearing that is fixed in chassis side rail, its rear end and swing arm lower end are hinged, the swing arm upper end is hinged with the arm swing support that is fixed in chassis side rail, above-mentioned drive axle places on the supporting plate, between this supporting plate and the above-mentioned gas spring base by bolted connection, the front end of supporting plate connects the rear end of stabilizer rod, and the front end of stabilizer rod is connected with the suspension rod lower end, and the suspension rod upper end is connected with chassis side rail.
Above-mentioned semiellipse steel spring can be stacked by two changeable section plate springs and form, and is tightened by spring buckle.
Above-mentioned semiellipse steel spring also can be stacked by three changeable section plate springs and form, and is tightened by spring buckle.
Above-mentioned chassis side rail is presented curved shape between double-convolution bellows type air spring top, fixed bearing and arm swing support.
The utility model is compared the beneficial effect that has with existing conventional art: the utility model is a kind of suspension form that combines with two double-convolution bellows type air springs and vertical semiellipse steel spring of putting.The semiellipse steel spring except playing the elastic element effect, also double playing the guiding role.The elastic element double-convolution bellows type air spring bears vertical load, make vehicle under different loads height and the rigidity of suspension remain unchanged substantially, when vibration takes place and impacts in vehicle, can the reasonable distribution load-carrying, relax and impact, damped vibration increases the traveling comfort of taking.The utility model has overcome the shortcoming of existing combined type air suspension, has simple in structurely, and the characteristics that cost is low can guarantee that automobile has good ride comfort and operation stabilization performance, fully satisfies the passenger vehicle operating needs.
