Another object of the present invention promptly has the vehicle that as above defines back axle assembly.
Description of drawings
The present invention and advantage thereof can be better understood through reading following narration, and they only are used as, and example is enumerated and the drawings attached reference, wherein:
-Fig. 1 has described first kind of enforcement formula for being the transparent view of the back axle assembly of foundation with the present invention;
-Fig. 2 has described first kind of variant implementing formula for being the transparent view of the back axle assembly of foundation with the present invention;
-Fig. 3 has described second kind of enforcement formula for being the transparent view of the back axle assembly of foundation with the present invention; With
-Fig. 4 is the transparent view after certain parts of Fig. 3 amplify in proportion.
The specific embodiment
In Fig. 3, the X of the system of axes that we adopted, Y, Z axle have defined the direction several commonly used of vehicle at Fig. 1, wherein:
-X axle is the longitudinal axis of vehicle, before pointing to from the back;
-Y axle is the lateral shaft of vehicle, points to a left side from the right side;
-Z is a vertical axes, from pointing to down.
In following narration, all directions and position are benchmark with the system of axes that this X, Y, Z axle are formed all.
What Fig. 1 described is the right part 10 of one and half deformable back axle assemblys, and a roller 12 of describing with thin dashed line is arranged on it, can be around 14 rotations of a roller support, and bearing itself is fixed on the stay bearing plate 16.
An end of this piece plate 16 and swing arm 18 links to each other, and another terminal fixed mount 19 that passes through of swing arm is in the same place with the car body hinge.
Crossbeam 20 connects together swing arm 18 and second swing arm that comes of not drawing to constitute a deformable back axle assembly of complete crossbeam.
Pendulum spring 22 1 ends that draw with long and short dash line are supported on the car body, and the other end is supported on the pedestal 24 of swing arm 18.Suspension damper 26 1 ends that draw with thin dashed line equally are supported on the car body, and the other end is supported in the swing arm 18.The system that is made up of spring 22 and bumper 26 has guaranteed suspension.
Stay bearing plate 16 links to each other through a Flexible Connector 28 with swing arm 18, allows that roller 12 has an extra degree of freedom with respect to swing arm 18, replys roller support 14 as far as possible around a rotation that is different from the rotating shaft of 12 on roller.
The rotating shaft of roller support 14 is parallel with the horizontal Y axle of vehicle substantially, and with roller 12 support ground on it be positioned at same horizontal surface or lower a bit.
Article one limit 30a, 32a and the swing arm 18 of every elastic plate link to each other, and second limit 30b, 32b link to each other with stay bearing plate 16. Elastic plate 30 and 32 can produce crooked along longitudinal direction of car X axle.
The additional degree of freedom that Flexible Connector 28 is introduced is corresponding to the longitudinal elasticity of allowing that roller 12 moves behind the longitudinal direction of car X axle.This effect can obtain embodying when certain obstacle begins to contact with roller 12.The power that is applied on the roller owing to bump can obtain buffering through moving behind the roller, to improve the comfort level of vehicle.When impact was cancelled, roller was owing to the elasticity of attaching parts 28 is returned to initial position then.
Back axle assembly 10 also comprises rigid plate 36 behind a preceding rigid plate 34 and in addition, and two boards all is fixedly connected in the swing arm 18.Article one limit 34a, 36a and the swing arm 18 of every rigid plate 34,36 link to each other, and second limit 34b, 36b are freely.Limiting stopper 40 is between two rigid plate 34 and 36 behind a front limit piece 38 (Fig. 2) that links to each other with the stay bearing plate 16 of roller support 14 and one.
Advantageously, a pad that does not draw is processed such as playing glue or rubber with elastomeric material, is inserted in the gap and the gap between front limit piece 38 and the preceding rigid plate 34 between back limiting stopper 40 and the back rigid plate 36.Roller support 14 has obtained realization through the Asymptotical Method of compression gasket with respect to the limit movement of swing arm 18 like this.
A bumper 42 that is used between swing arm 18 and the roller support 14 has reduced the kinetic energy of roller support 14 with respect to swing arm 18 motions.This bumper is suitable for reducing the kinetic energy of roller support (14) with respect to swing arm (18) motion.
According to the enforcement formula that Fig. 1 draws, bumper 42 is telescopic, comprises one and prolongs 44 and bars 46 of stretching in the tube outside of pipe.Bumper 42 back terminal 48, also promptly and to manage 44 bonded assemblys terminal, hinged with a support 50 above the stay bearing plate that is installed in roller support 14 16.Bumper 42 preceding terminal 52, also be the free end of bar 46 and be connected on before a support 54 above the rigid plate 34 hinged, this support 54 is positioned near the free edge 34b.Bumper 42 is gas type or oil type, such as the sort of type of vehicle box jack commonly used.
What Fig. 2 described is to implement a variant of formula according to of the present invention first.For chart clear for the purpose of, suspension is not drawn, parts similar with each parts among Fig. 1 keep their reference number.Gas type or oil type bumper 142 show a housing 144 and a bar 146 of stretching in the housing outside.Housing 144 is fixed on the front limit piece 38 and is integrated, and pad has not just had in this case.The preceding end of bar 146 is through on the rigid plate 34 before being hinged on such as a spherical coupling.
Fig. 3 describes is according to second enforcement formula of the present invention, for chart clear for the purpose of, suspension is not drawn, the parts similar with each parts in the prior figures keep their reference number.
Bumper 242 is rotary-type, comprises the housing 244 that is fixed on above the brace panel linking to each other with swing arm 18 56, the spiral arm 246 that rotates around housing 244 along axle 248 (Fig. 4) with longitudinal direction of car Y substantially parallel axes.Spiral arm 246 is connected on the stay bearing plate 16 of roller support 14 through its free end 250 (Fig. 4).Rotary-type bumper 242 is the hydraulic bumper, such as motor bike steering hardware the sort of type commonly used.
Now running of the present invention will be described.When a longitudinal force is applied to 12 last times of roller along the arrow F shown in Fig. 1 to 3, the latter since the elasticity of attaching parts 28 with after move.Before elastic plate 30, originally the interval is arranged with preceding rigid plate 34, will bend and rely on the latter.Simultaneously back elastic plate 32 will bend and away from back rigid plate 36.Do not draw be supported on the pad of back on the limiting stopper 40 by back rigid plate 36 progressive compressions to avoid producing noise.Meanwhile, bumper 42,142,242 end 48, the housing 144, terminal 250 separately that is connected on the stay bearing plate 16 of roller support 14 moves after following roller 12.Bumper 42,142 and 242 has reduced the kinetic energy of roller support with respect to the swing arm campaign.After the power F cancellation, elastic plate 30 and 32 is because their crooked elastic returnings that is produced arrive original position, and bumper 42,142 and 242 will reduce roller support again with respect to swing arm 18 heterodromous kinetic energy.
Because the present invention, roller support has obtained buffering with respect to a rotation that is different from the rotating shaft of roller shaft, and vertical elasticity that this has improved half deformable back axle assembly has also improved comfort level for the passenger of vehicle.In addition, the employing of bumper can not reduce the highway performance of vehicle, and its cost per unit is very low, and the economy of production still keeps.
