Be coupled the mechanical type torsion dissipating hanging frame entirely and shown in Figure 15 a kind ofly as the mechanical type torsion dissipating hanging frame that is coupled entirely that the suspension elastic element constitutes implementation of the present invention be described as what the suspension elastic element constituted with leaf spring below in conjunction with a kind of shown in the accompanying drawing 1 to 4 with leaf spring.
Shown in Fig. 1-4, leaf spring of the present invention is coupled the mechanical type torsion dissipating hanging frame entirely and comprises that middle part (i.e. " lower end ") is fixed in the leaf spring on each axletree, the two ends (i.e. " upper end ") that it is characterized in that each leaf spring by pivotally attached in the same way communtation arm 4,4 ', 7,7 ' be coupled mutually with the pull bar 5,8 of this two ends communtation arm that is hinged, communtation arm 4,4 on the forward and backward leaf spring 1,2 of homonymy ', 7,7 ' each other is reverse; The communtation arm 4 of forward and backward leaf spring 1, the 2 green phase neighboring terminals of homonymy ', 7 pivotally attached pull bars 6 are oppositely and are coupled; Left and right sides leaf spring is oppositely it by a bindiny mechanism and is coupled.
As shown in figure 15, coil spring complete-couple type torsion dissipating hanging frame of the present invention, the coil spring 61 that comprises each wheel of supporting, two coil spring 61 upper ends that it is characterized in that homonymy are bearing in a middle part and are articulated on the two arm ends of three end equilibrium arms 62 on the vehicle frame, and the middle-end of three end equilibrium arms 62 of the left and right sides is hinged mutually by equilibrium arm 10 two ends that propelling rod 63 and middle part are articulated on the vehicle frame respectively.
Its principle of work:
1. the vertical input analysis in the road surface of automobile
With the diaxon vehicle is example, and the four-wheel suspension produces four vertical constraints to vehicle body, and vehicle body is played the role of positioning.To the corresponding road roughness input of its four-wheel q
i(i=1,2,3,4,1-off front wheel, 2-the near front wheel, 3-left rear wheel, 4-off hind wheel) always can be decomposed into four components: the average vertical input q in road surface, and the average inclination input in road surface , the average pitching input in road surface θ, the road surface is to turning round input τ.From the vehicle body plane positioning is required, guaranteeing the automobile plane motion freely under the prerequisite, three vertical location are enough, and the 4th was just caused the location.If wheel of cancellation was certainly eliminated the location, but damaged the stability of automobile.How do not damage automobile vertically with the prerequisite of lateral stability under, elimination is exactly the purpose that this patent will reach to the torsional restraint of vehicle body.Conversion is carried out in four-wheel input, can be got elevation q, inclination, , trim θ and reverse four kinds of mode of τ:
Wherein, B
1, B
2Be the front and rear wheel distance, L is a wheelbase; If can find the coupled modes between the four-wheel suspension to make it to keep q under the condition of four-point supporting, , three constraints of θ, (design is coupled mechanism makes the additional displacement of the upper end of suspension elastic element satisfy (Δ q to reversing the constraint of importing τ and cancel unnecessary vehicle body
1-Δ q
2)/B
1+ (Δ q
3-Δ q
4)/B
2=0 condition can make and reverse input τ=0), and make each wheel load uniformization, this will play the elimination tersional stress to the automobile that travels on uneven road surface, improve riding comfort and crossing ability is highly beneficial.
2. system work process and principle.
Being coupled formula torsion dissipating hanging frame vehicle (Fig. 3) entirely with the diaxon leaf spring below is example, and the principle of work of this novel suspension fork mechanism is described:
A) when wheel is subjected to the input of ground-surface vertical deviation, pull bar 5,6,8,9 stressed left-right symmetric, equilibrium arm 10 is in the moment balance state, and communtation arm 4,7 all is in motionless state with equilibrium arm 10.This moment, novel suspension system was equivalent to conventional suspension system.
B) when wheel was subjected to the input of road surface side inclination angle, for example left side wheel made progress, and right side wheels moves downward.Suitably the transmitting ratio of design communtation arm 4,7 balances each other pull bar 6 two ends power.The pulling force of two lateral bracing struts 9 remains unchanged, and equilibrium arm 10 systems still are in the moment balance state, does not have and rotates.That is, under road surface inclination input, novel suspension system is equivalent to conventional suspension.
C) when wheel was subjected to road surface pitch angle input, front-wheel moved downward, the trailing wheel upward movement.Pull bar 5,6,8,9 stressed left-right symmetric, equilibrium arm 10 is in the moment balance state, and communtation arm 4,7 all is in motionless state with equilibrium arm 10.This moment, novel suspension system was equivalent to conventional suspension system.
D) but be subjected to the road surface to turning round when input when wheel, for example, right front, left back wheel upward movement, left front, right rear wheel moves downward, right side pull bar 5,6,8,9 move left side pull bar 5,6 backward, 8,9 move backward, because the equilibrium activity of equilibrium arm 10, the power of left and right sides bar 9 equates.Relatively moving of left and right sides pull bar 5,6,8,9 promotes equilibrium arm and produces clockwise rotation, makes the additional vertical force unloading of each suspension then, eliminates the wheel load variations and to the torque load of vehicle body.
In sum, novel suspension system is by the moment balance of four suspension application forces to equilibrium arm or commutation trammel beam, can offset in the road excitation to turning round the influence of component, make four-wheel load uniformization, thereby when having guaranteed that vehicle travels on uneven road surface, have good ground connection property, alleviate inhomogeneous caused vehicle body torque load, improve the travel crossing ability and the ride comfort of vehicle because (diagonal angle) wheel is loaded.
