Abstract
The utility model relates to air suspensions for automobiles, in particular to an independent suspension for a driving axle of a single wide tire, which comprises a main reducer assembly, a frame, a hub support and a suspension system. The independent suspension is characterized in that the main reducer assembly is connected with the frame by the aid of four fulcrums, and the hub support is connected with the main reducer assembly by the aid of parallelly arranged double arms of vertically equal lengths in the suspension system. The independent suspension with the structure has the main advantage that original non-suspension laden mass along with jouncing of wheels is greatly decreased.
Description
Technical field
The utility model relates to the air suspension that automobile is used, and the wide tire drive axle of particularly a kind of list is used independent suspension.
Background technology
The rear suspension of full-sized car is whole bridge-type twins dependent suspension at present.The development a lot of passenger vehicles technological along with passenger vehicle all adopt rear-mounted engine.Change common twins leaf spring type dependent suspension into twins air spring type dependent suspension.Because suspension is a kind of its non-outstanding charge material amount of elastic element system that damping vibration attenuation arranged (being the quality below the elastic element) vibration characteristic is had very important influence, therefore, the non-outstanding charge material amount big vibration characteristic that heals is poorer.
In addition, traditional dependent suspension, driving engine is to be fixed on the vehicle frame together with transmission assembly with the wheel bob owing to whole vehicle bridge (containing main gearbox assembly).So just a telescopic transmission shaft must be installed between change-speed box and main reduction gear.Consider driving efficiency and prevent wheel significantly during bob joint yoke stuck, this transmission shaft can not be lacked very much (between general two universal-joints distance can be less than 350 millimeters).Thereby the arrangement form of this transmission just makes the passenger vehicle of 7 meters to 9 meters of head factories be difficult to do wheelbase greatly causes the antero posterior axis load distribution unreasonable.Axle load also can only account for about 28% of gross weight before general, even littler.Because preceding axle load is too small, causes motor turning out of control easily, consequence was more serious when particularly empty wagons was climbed.

The specific embodiment
The utility model provides the wide tire drive axle of a kind of list to use independent suspension, and its main purpose is to reduce non-outstanding charge material amount.Comprise main gearbox assembly, vehicle frame, wheel hub holder and suspension system in its main project organization; It is characterized in that: this main gearbox assembly links to each other with vehicle frame by four fulcrums, the wheel hub holder by in the suspension system up and down the isometric both arms that are arranged in parallel link to each other with main gearbox assembly.The utility model is designed to after the independent suspension, the drive axle cancellation of non-integral, and main reduction gear is fixed on the vehicle frame together with its housing, and the non-outstanding charge material amount that so just will originally beat together in company with wheel significantly reduces.
See also Fig. 1,2, it is the structural representation of the wide tire drive axle of the utility model list with independent suspension one preferred embodiment.As shown in the figure: it comprises the suspension system that is arranged on vehicle frame 5 belows; This suspension system includes left and right Top Crossbeam 3, left and right lower cross arm 4, air bellow 1 and vibration damper assembly 10; These speed reducer assembly 10 upper ends are hinged on the vehicle frame 5 through reducer stent 15, the lower end then be hinged on be positioned at the suspension system both sides with Top Crossbeam 3 and the wheel hub holder 11 captiveed joint in lower cross arm 4 outer ends on; Captive joint with vehicle frame 5 through air-bag support 14 in this air bellow 1 upper end, the lower end then is fixedly connected on the wheel hub holder 11; A hinged main gearbox assembly 6 between this left and right Top Crossbeam 3 and the left and right lower cross arm 4, these main gearbox assembly 6 upper ends are hinged on the vehicle frame 5 through main reduction gear support 13; This main gearbox assembly 6 is in transmission connection with non-telescoping cross-axle universal shaft driving device 8, and this 8 of non-telescoping cross-axle universal shaft driving device and left and right transmission shaft 2 the inners between left and right Top Crossbeam 3 and left and right lower cross arm 4 are in transmission connection; Be arranged with left and right half sleeve pipe 16 respectively on this left and right transmission shaft 2, and its outer end connects single wide tire respectively; This main gearbox assembly 6 also is fastened on the transmission assembly on the vehicle frame 5 through elastic coupling 7.On the wheel hub holder 11 axle tube 16 and brake clamp are housed, the wheel hub that brake disc and single wide tire are housed is fixed on the axle tube 16.Brake chamber assembly 9 is fixed on the wheel hub holder 11.Wherein brake clamp and brake disc are the parts of disk brake assembly 12.
The foregoing description has following design feature and design effect.
1, the utility model embodiment be by four on the bevel housing name a person for a particular job that main reduction gear links to each other with vehicle frame and left and right wheels be by about two transverse arms wheel is linked to each other with bevel housing; Left and right open circuited semiaxis borrows non-telescoping transmission to link to each other with left and right sides wheel hub, and the non-outstanding charge material amount that so just will originally beat together in company with wheel significantly reduces.
2, the utility model embodiment adopts single wide tire, is for the length of place, the extension shaft limit transmission shaft lateral slip between tire and ground when reducing wheel bounce on the one hand, also can reduce non-outstanding charge material amount on the other hand.On the basis of above-mentioned loss of weight, adopted plate disc brake to replace traditional drum brake mechanism again, the weight that has not only significantly reduced car load can also be improved deceleration and stopping performance.
3, among the utility model embodiment since main deceleration assembly, transmission assembly and engine assembly all be fixed on the same vehicle frame.During the automotive wheel bob, the possibility that has not vertically moved between each assembly in theory, change-speed box can rigidity dock with main reduction gear in theory.But consider the problem of the aspect such as elastic deformation and accuracy of manufacture of driving engine rubber bearing, change-speed box and main reduction gear are connected together with an elastic coupling.Learn that by automobile theory the spring in the independent suspension so this kind suspension pattern lateral angle rigidity is very big, can not install transverse arresting apparatus apart from being wheelspan additional.
4, the utility model embodiment suspension is compared gross weight with traditional four gasbags dependent suspension and is fallen 100 kilograms at least, and this has not only improved the ride comfort of automobile, can also reduce the consumption of fuel of car load.In addition owing to adopt the elasticity drive coupling to replace telescopic transmission shaft; Can be short passenger vehicle (passenger vehicles that length overall is 7 meters to 9 meters) and brought the comfort feature of arranging; Wheelbase increasing, rear overhang are shortened, and the distribution of axle load of antero posterior axis more becomes rationally, has solved automobile operation problem out of control.
Being merely the preferred embodiment of the utility model in sum, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be the technological category of the utility model.
