J is arrogant. He turns into the center and the elastic member 18 reaches the spring. The distance s is increased by Q to increase (P + Q). The front-to-back distance between the flat member 19 and the member 18 ^ μ is as shown in FIG. 2 ′. The distance p from the self-loading wheel center C1 to the elastic structure 与 and the self-loading are increased. , 19, both, the durability of the two elastic members 18,19 will be more, that is, by adding the negative branch ^% input to the beam 1 through the tracking arms 4a, 4b (point of elastic member 18): The movement of the lower elastic member 19 acts on the elastic member 19: the direction negative Wr becomes larger, and the load Wf acting on the elastic member direction becomes smaller. Therefore, when the distance from the upper and lower member 18 to the p disk is self-storage // minus: the loss center C1 to the elasticity ^ ^ ί Γ ;: νΛ ". ^ ^ # # 19 ^ Shangxiagu a & ) / 2}, the negative direction Wr acting on the elastic member I meets the load M acting on the elastic member 19 in the up and down direction: the two loads will be evenly distributed, and the durability of the two elastic members 18, 19 is sitting; In order to reduce the input offset for beam 1, it can be avoided when setting the load input center value to satisfy the formula. Page 15 7042-6297-PF (N2); Ahddub.ptd 200426049 V. Description of the invention ( 12) The extreme up-down load in the front-back direction is avoided, and practically, the durability of the two elastic members 18, 19 can be fully improved. Formula 1: {(P + Q) / 2} X 〇 · 7 $ Ρ $ {(P + Q) / 2} X 1.3 Especially as shown in the embodiment, it becomes a hub that supports the rear wheel 丨 〇 When the three parts of the member π, the support part of the coil spring 14 and the follower arms 4a and 4b are arranged on a straight line (the points ff / s, 3 and ^ are on the α line), the elasticity is elastic. Components 丨 8, j 9 Easy to generate eccentric load (arranged in a straight section, which will form a load transmission path in the up and down direction), the elastic member is set at a position approximately the same as the coil spring 14 position in the front-back direction , Can effectively make the input on the elastic members 18, 19 uniform. The door does not make the spring constants of the respective elastic members 18, 19 the same (when the spring constants of the two are the same, the elastic center C2 is located at an equal distance from the F and R points), as shown in Figure 2, by Adjust the number of each of the elastic members 18, 19 to two, so that the elastic center C2 of each of the elastic members 18, 19 is close to the negative of the beam ^; when the center ci is input, it can reduce the two centers that are the reasons for the rise of the beam ^ . As a result, the amount of upswing of the beam 1 relative to the load input will be reduced, and the vehicle stability will be improved. μ ΠΓ Ϊ ie i Ϊ sets the number of straight wheels of two elastic members 1 8 arranged in the transverse direction of the vehicle to ί, and the number of suspensions is set to a. It is represented by Za = Wf / a, and the amount of displacement in the elastic direction is represented by Zb = w " b. In addition, when the distance between ~ C2 and the elastic member 18 is set to ϋ, ϋ = page 16 7042-6297-PF (N2); Ahddub.ptd 200426049 V.

At this time, as shown in FIG. 5, when the deviation is far from the center of the bullet C1 in the center C 1, Q AM t is the difference between the negative and the current status, ηΛΛ, and the displacement of the elastic member 19 The difference fi of zb will be relatively large. In addition, when the appropriate number of seconds b, the deviation value is relatively small Γ, now =: two numbers: and spring constant ^ λΪ-4- ^ L / zL 1 Π Behe The displacement amount Za of the elastic member 18 and the displacement amount Zb of the elastic member 18 in the input center C l

A relatively small value can reduce the amount of disruption. S, and when the deviation is set to 0, the current load input center 0, the piece movement amount Za and the elastic member 19 displacement amount bracket will be equal, where 'the amount can be changed to 0, and the vehicle can be manipulated ~', When the deviation τ satisfies the formula 2, it is practically used horizontally: "This will reduce the charge, and improve the vehicle's handling and stability. Formula 2 IO.IUSTSO" {(P + Q) _U}-Heart again: Λ When the elastic member 19 is set, the elastic member u is disposed on the inner side of the vehicle than the chasing St. Therefore, the chasing up and down can be avoided: the arm L4b interferes with the elastic member 19, and the input invention can be improved: ΐ r ϊ ϊ: ί: 偈 is limited to one embodiment, as long as it does not deviate from this: various changes belong to the scope of the present invention. Also in the second κ configuration, although the configuration in which the first elastic member is disposed on the front side i 'is exemplified, the first elastic member may be disposed at the same position as the beam, and the first elastic member may be disposed on the horizontal end. Another example is-in the embodiment, "Although the use of an E-shaped bracket is used to make the vehicle bounce at the rear of the vehicle, page 17 7042-6297-PF (N2); Ahddub.ptd 200426049 V. Description of the invention (14) The component is arranged in a spiral with Therefore, other components may be used. In addition, for example, after using a differential device, it is used in a mode without differential application. Although it is exemplified, it is not limited to the full follow-up arm of the receding angle. Although the elastic point is set in the front-rear direction of the vehicle The outer peripheral surface and the coil spring 14 are approximately similar to the suspension device of the present embodiment. The device can be suspended after being used after the device is suspended. The bullet of the component 19 is approximately the same, the outer peripheral surface is located at the same position and the elastic yellow is approximately the same position, but it is not limited in structure and is set at approximately the same position as the coil spring in one embodiment. Although the present invention is used, it does not Limited to this, the device may be suspended. For example, the suspension of the follower arm at half of a real receding angle enables the present invention to be used without. In the above embodiment, the exemplary center R and the helical spring 14 4s are the same. However, when at least the elastic member 19 is the same Position can also be obtained with the effect. [Effects of the invention] Wheels: When items 1, 6 and 7 of the hoisting range, the i-th elastic member from the front side is placed in the vehicle, and can be prevented from damaging the durability of the two elastic members. = Medium durability.
