The specific embodiment
The utility model provides a kind of independent suspension for driving axle structure, and its main purpose is to reduce non-outstanding mounted mass, improves road-holding property and the safety of vehicle and realize that the axle axle load distributes more rational.Its main project organization comprises main gearbox assembly, vehicle frame, wheel hub holder and suspension system; It is characterized in that: this main gearbox assembly is connected with vehicle frame by fulcrum, and the wheel hub holder is connected with main gearbox assembly by the not isometric both arms of arranging up and down in suspension system.After the utility model was designed to independent suspension, the drive axle of non-integral was cancelled, and main reduction gear is fixed on vehicle frame together with its housing, and the non-outstanding mounted mass that so just will originally beat together in company with wheel greatly reduces.
See also Fig. 1,2, it is the structural representation of the utility model independent suspension for driving axle one preferred embodiment 1.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; This speed reducer assembly 10 upper ends are hinged on vehicle frame 5 by reducer stent 15, the lower end be hinged on be positioned at 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 by air-bag support 14 in this air bellow 1 upper end, the lower end is fixedly connected on takes turns on hub holder 11; A hinged main gearbox assembly 6 between this left and right Top Crossbeam 3 and left and right lower cross arm 4, this main gearbox assembly 6 upper ends are hinged on vehicle frame 5 by main reduction gear support 13; This main gearbox assembly 6 is in transmission connection with cross-axle universal shaft driving device 8, and 8 of this cross-axle universal shaft drivings 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 respectively left and right half sleeve pipe 16 on this left and right transmission shaft 2, and its outer end connects respectively single wide tire; This main gearbox assembly 6 also is fastened on transmission assembly on vehicle frame 5 by elastic coupling 7.
In addition, on wheel hub holder 11, axle tube 16 and brake clamp are housed, the wheel hub that brake disc and tire are housed is fixed on axle tube 16; Brake chamber assembly 9 is fixed on wheel hub holder 11.Wherein brake clamp and brake disc are the parts of disk brake assembly 12.
Above-described embodiment has following design feature and design effect.
1, the utility model embodiment be by on bevel housing name a person for a particular job that main reduction gear is connected with vehicle frame and left and right wheels to be not isometric pair transverse arm by the left and right be connected wheel with bevel housing, the semiaxis of left and right disconnection borrows transmission shaft to be connected with the left and right wheel hub, and the non-outstanding mounted mass that so just will originally beat together in company with wheel greatly reduces.
2, the utility model embodiment has adopted plate disc brake to replace traditional drum brake mechanism, and the weight that has not only greatly reduced car load can also be improved deceleration and stopping performance.
3, in the utility model embodiment because main deceleration assembly, transmission assembly and engine assembly all are fixed on same vehicle frame.During the automotive wheel bob, the possibility that has not vertically moved between each assembly, change-speed box can rigidity dock in theory with main reduction gear.But consider the problem of the aspects such as the elastic deformation of driving engine rubber bearing and accuracy of manufacture, with an elastic coupling, change-speed box and main reduction gear are connected together, learnt by automobile theory, spring in independent suspension is apart from being wheelspan, therefore this kind suspension pattern lateral angle rigidity is very large, can not install transverse arresting apparatus additional.
4, the utility model embodiment suspension is compared gross weight and is significantly reduced (reducing at least 100 kilograms) with traditional four gasbags dependent suspension, 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 adopting the elasticity drive coupling to replace telescopic transmission shaft, can be the comfort feature that shorter passenger vehicle (passenger vehicles that overall length is 7 meters to 9 meters) has brought cloth to be set up, wheelbase increasing, rear overhang are shortened, the axle load of antero posterior axis distributes more rational, solve easily problem out of control of automobile operation, improved its safety performance.
5, this suspension design is not isometric pair transverse arm, can accurately control the wheel alignment parameter of car load, thus improve car load control stability and safety.Reduce simultaneously wear on tyres, reduce user's use cost.
As a kind of variation, the utility model also has another embodiment, and this routine structure is substantially the same manner as Example 1, and difference is: described driving device 8 is coupler.Drive coupling is a kind of ball cage type structure, and its advantage is long service life, and reliability is high, and noise is low, is not subjected to the restriction of two cross arm structures.Thereby reduce user's use cost.Shortcoming: cost is higher, and is higher to the road conditions requirement of Vehicle Driving Cycle.
Being only preferred embodiment of the present utility model in sum, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should be technology category of the present utility model.
