Description
Technical field
The utility model relates to automotive field, is specifically related to a kind of automotive suspension.
Background technology
Automotive suspension is vehicle body (or vehicle frame) for connecting automobile and the connecting device between vehicle bridge (or wheel), its effect is the force and moment of transfer function between vehicle bridge and vehicle body, and buffering is passed to the impulsive force of vehicle body by uneven road surface, and the vibrations that decay and cause thus, to guarantee that automobile can smooth-going travelling.

The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can more be become apparent, below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
The utility model embodiment provides a kind of automotive suspension, with reference to Fig. 2-3, comprise shock absorption device 30 and bracing or strutting arrangement 10, bracing or strutting arrangement 10 is positioned at outside shock absorption device 30 and is connected in shock absorption device 30 one end, and automotive suspension is connected with vehicle body (not shown) by bracing or strutting arrangement 10.That is to say, in the present embodiment, bracing or strutting arrangement 10 is between shock absorption device 30 and vehicle body, and its function is to substitute existing surface bearing and damper element, for the connection between shock absorption device 30 and vehicle body.Below will the concrete structure of bracing or strutting arrangement 10 and the surface bearing playing thereof and damper element function be made to labor.
Bracing or strutting arrangement 10 comprises that the first magnet 11 that relative spacing arranges and the second magnet 12, the first magnets 11 are for being connected with vehicle body, and the second magnet 12 is connected with shock absorption device 30.
Two end magnetic poles that the first magnet 11 is relative with the second magnet 12 are identical; The second magnet 12 can move towards or away from the first magnet 11, also can rotate with respect to the first magnet 11.
The two ends that the first magnet 11 is relative with the second magnet 12 produce repulsive force because Magnetic Phase is same, and this repulsive force can be used as the bearing force of suspension to vehicle body, between shock absorption device 30 and vehicle body, plays a supporting role; The second magnet 12 can rotate with respect to the first magnet 11, and shock absorption device 30 can be rotated with respect to vehicle body.Visible bracing or strutting arrangement 10 can instead of flat spherical bearing effect.
With reference to Fig. 2-3 and in conjunction with Fig. 4, repulsive force between the first magnet 11 and the second magnet 12 is nonlinearities change along with the variation of distance between the first magnet 11 and the second magnet 12, wherein F represents the repulsive force between the first magnet 11 and the second magnet 12, X represents distance between the first magnet 11 and the second magnet 12, and the slope of curve A each point has represented the rigidity of whole bracing or strutting arrangement 10.
As can be seen from Figure 4:
When dynamic excitation hour, the distance between the first magnet 11 and the second magnet 12 is larger, and change of distance is little, the repulsive force producing is less, now the support stiffness of bracing or strutting arrangement 10 is less, the ride comfort in the time of can guaranteeing running car like this;
When dynamic excitation is larger, the distance between the first magnet 11 and the second magnet 12 is dwindled, and sharply variation of distance, and it is large that the repulsive force producing becomes rapidly, and the support stiffness of bracing or strutting arrangement 10 can become greatly fast, and then the stability of assurance vehicle body.
Visible, the support stiffness of bracing or strutting arrangement 10 can regulate automatically along with the motoring condition of automobile, and remains good durability.By the way, bracing or strutting arrangement 10 can also, as damper element, play buffer action between suspension and vehicle body.
Wherein, the size of the first magnet 11, the second magnet 12 can be selected according to the needs of support stiffness.
In the present embodiment, the first magnet 11, the second magnet 12 are column, in other embodiments, also can adopt other shapes.
Continuation is with reference to Fig. 2, and bracing or strutting arrangement 10 also comprises that shell 13, the first magnets 11 and second magnet 12 with column through hole are arranged in column through hole coaxially, along the axial array of through hole;
The first magnet 11 is fixedly arranged in through hole, and the second magnet 12 can rotate with respect to shell 13, and can endwisely slipping along column through hole in shell 13.
Between the second magnet 12 and the inwall of shell 13, be provided with ball 14.Ball 14 can reduce the friction between the second magnet 12 and shell 13 inwalls on the one hand, on the other hand due to diametrically, the second magnet 12 is arranged between ball 14, ball 14 can play the radially position-limiting action to the second magnet 12, prevent that the second magnet 12 from causing run-off the straight when stressed owing to radially producing deviation, guarantee that the second magnet 12 is parallel with the first magnet 11 all the time when rotating or moving vertically, can so that the first magnet 11 stressed parallel with the axis of column through hole, guarantee the stability of vehicle body like this.
In shell 13, the inwall of column through hole need to have certain surface accuracy, so that the second magnet 12 can rotate and slide in through hole.
One end that the second magnet 12 is relative with the first magnet 11 is connected with elastic component 15.Dynamic excitation is excessive while causing between the first magnet 11 and the second magnet 12 too small the or contact of distance, elastic component 15 can be avoided between the two because direct impact damages.
Elastic component 15 is rubber parts.In other embodiments, elastic component 15 can be also other materials, as long as can play buffering energy-absorbing function.
In the first magnet 11 and the second magnet 12, be formed with coaxial connecting bore (not mark), the axially parallel of the axial and column through hole of connecting bore.
Bracing or strutting arrangement 10 also comprises strut member 16, is positioned at the opposing one end of the first magnet 11 and the second magnet 12, and strut member 16 is connected with shell 13, and the first magnet 11 is connected with vehicle body by strut member 16.
Shock absorption device 30 comprises bumper 31 and spring 32, bumper 31 has cylinder body 31a and is inserted in the piston rod 31b of cylinder body 31a, piston rod 31b passes connecting bore, is connected with strut member 16 with respect to the other end of cylinder body 31a, wherein, piston rod 31b does not contact with the second magnet 12 with the first magnet 11, that is to say, the diameter of piston rod 31b is less than the internal diameter of connecting bore, avoids occurring interfering between bumper 31 and bracing or strutting arrangement 10.
Spring 32 be positioned at the second magnet 12 and the opposing one end of the first magnet 11, be sheathed on outside bumper 31, one end of spring 32 is connected with the second magnet 12, the other end is connected with cylinder body 31a.
In the present embodiment, spring 32 is connected by the first spring holder 51 with the second magnet 12; Spring 32 is connected by the second spring holder 52 with cylinder body 31a.
It should be noted that, strut member 16 is for connecting automotive suspension and vehicle body, and its material can be chosen according to actual conditions, and punching press shape can be adjusted according to actual arrangement situation; In the present embodiment, between strut member 16 and shell 13, be welded, and preferably can guarantee the first magnet 11 and the opposing one end of the second magnet 12 can and strut member 16 between good laminating.
In the present embodiment, automotive suspension is McPherson strut, and bumper 31 is same as the prior art with the connection mode of spring 32.
In other embodiments, automotive suspension can be also other forms, as long as meet between suspension and vehicle body, with bracing or strutting arrangement 10, is connected.
To sum up, in the present embodiment, adopt the first magnet 11, the second magnet 12, as bracing or strutting arrangement, automotive suspension is connected in to vehicle body, can play the effect of prior art midplane bearing and damper element simultaneously, whole bracing or strutting arrangement has better durability.
