Abstract

The utility model relates to a single-longitudinal arm independent suspension for a vertical elastic cell. The supporting seat of a control arm is arranged on a vehicle frame and one end of the control arm is supported on the supporting seat of the control arm through the shaft of the control arm and can do rocking motion winding the supporting seat of the control arm. A position approaching to a wheel shaft on the other end of the control arm is provided with a lower bracket for the vertical elastic cell, and another upper bracket as the support of the vertical elastic cell is arranged on the vehicle frame and above the lower bracket. The vertical elastic cell is arranged between the upper bracket and the lower bracket, and the structure can decrease the bending moment received by the control arm, simplify the structure of the vehicle frame and enable the inner space of some vehicles to be utilized more reasonably.

Description

Single-longitudinal arm independent suspension for vertical elastic cell

The invention belongs to the structure of a kind of independent suspension of vehicle, specifically, it is with the vertical independent suspension frame unit of single Control arm as director element of putting.

Existing single longitudenal arm independent suspension is with its elastic element (coil spring for example, rubber spring, plastics spring etc.) be arranged on the vehicle with the bumper along continuous straight runs, its floor raised be unfavorable for carrying out rational car load to be arranged thereby this structure is used in some dillies; In addition, the suffered load of wheel will vertically be put single Control arm and is delivered to elastic element and vehicle frame again by whole, makes Control arm bear very big bend loading, thereby easily produces distortion and can produce very big local stress at some position.

The objective of the invention is the structure by changing elastic element in the single longitudenal arm independent suspension and arrange, make it in some vehicles, to obtain more reasonably using to solve above-mentioned the deficiencies in the prior art part.

The design's major measure is: at the single longitudenal arm independent suspension lower bracket that supports below as the vertical type elastic element is set near the position of axletree; Above lower bracket, from vehicle frame another upper bracket as vertical type elastic element upper support is set, the vertical type elastic element promptly place above-mentioned on, between the lower bracket.Crossing its wheel of uneven road surface when vehicle ' does with respect to vehicle frame, under when moving, the amount of compression of above-mentioned elastic element also changes thereupon, thereby play the buffering of draft hitch, cushioning effect, on the vertical type elastic element, lower bracket all can make the structure of hanger (hinge pin) formula, to adapt to better on the relative vehicle frame work of wheel, when moving down because of vertical put that single Control arm causes on, the front and back relative motion of following two stands, on above-mentioned, be provided with the guiding mechanism of above-mentioned elastic element between the lower bracket, it is contained in the inner face or the outside of vertical type elastic element deviates from from support in order to prevent above-mentioned elastic element, and above-mentioned guiding mechanism is generally two can be along the bearing fit mechanism of its longitudinal extension, for compact conformation can be combined telescopic shock absorber and above-mentioned elastic element, promptly telescopic shock absorber is installed within the vertical type elastic element and with the hanger at its two ends do above-mentioned elastic element on, lower support, the guiding mechanism of the piston rod of bumper and cylinder barrel double as vertical type elastic element.

Below in conjunction with description of drawings the design's a embodiment, the present invention is not limited to this embodiment.

Preceding (back) that accompanying drawing 1 installs on vehicle for vertical type elastic element single longitudenal arm independent suspension is to view.

The lateral plan that accompanying drawing 2 installs on vehicle for above-mentioned single longitudenal arm independent suspension, the A-A that takes from accompanying drawing one analyses and observe.

Accompanying drawing 1.2. mark sequence number is expressed as follows:

1 vehicle frame, 9 lower brackets

2 Control arm bearings, 10 hinge pins

3 Control arms, 11 crossbeams or support

4 control arm axles, 12 hinges

5 wheel shafts, 13 upper brackets

6 wheels, 14 cylinder barrels

7 bottom brackets, 15 piston rods

8 elastic elements

Accompanying drawing 1,2 illustrate, on vehicle frame ［ 1 ］, be provided with the Control arm bearing ［ 2 ］ of single longitudenal arm independent suspension, the vertical single Control arm ［ 3 ］ of putting is supported on the Control arm bearing ［ 2 ］ by control arm axle ［ 4 ］, and can do gyroscopic movement or oscillating motion around its center, the other end of Control arm ［ 3 ］ is provided with wheel shaft ［ 5 ］, and wheel ［ 6 ］ is supported on the wheel shaft ［ 5 ］ by bearing.Position at the close wheel shaft ［ 5 ］ of Control arm ［ 3 ］ is provided with bottom bracket ［ 7 ］, the lower bracket ［ 9 ］ of vertical type elastic element ［ 8 ］ cuts with scissors knot by hinge pin ［ 10 ］ mutually with bottom bracket ［ 7 ］, vehicle frame ［ 1 ］ is provided with crossbeam or support ［ 11 ］ has hinge to cut with scissors knot mutually with the upper bracket ［ 13 ］ of elastic element ［ 8 ］ in its side, above-mentioned vertical type elastic element ［ 8 ］ can make coil spring, disk spring, rubber spring, plastics spring.On elastic element ［ 8 ］, lower bracket ［ 13 ］ can be provided with the cylinder barrel ［ 14 ］ and the piston rod ［ 15 ］ of telescopic shock absorber between ［ 9 ］, and both can endwisely slip and produce certain dumping force along it, promptly make the guiding mechanism of vertical type elastic element simultaneously.Above-mentioned guiding mechanism also can make the garden cylindrical component and be wrapped in the outside of elastic element ［ 8 ］ or be placed in it.Above-mentioned when having the vehicle ' of single longitudenal arm independent suspension, along with the variation of service load on the tire or be subjected to the effect of Uneven road, wheel ［ 6 ］ will constantly be done around the center O of control arm axle ［ 4 ］, lower swing, simultaneously elastic element ［ 8 ］ thus reduction length also change the bumper and absorbing shock effect that plays draft hitch thereupon.On Control arm ［ 3 ］, during lower swing, bottom bracket ［ 7 ］ is also thereupon together around the O spot wobble, therefore, name a person for a particular job 2 relative motions that have along longitudinal direction of car of center O of upper bracket ［ 13 ］ of relative resilient element ［ 8 ］ of its center O1, when the upper bracket ［ 13 ］ of elastic element ［ 8 ］ and lower bracket ［ 9 ］ adopt hanger or hinge pin formula structure, can make it in longitudinal plane, to freely swing, now look like thereby produce buckling can avoid elastic element ［ 8 ］ work the time.

Above-mentioned single longitudenal arm independent suspension since the supporting-point of elastic element ［ 8 ］ and wheel shaft ［ 5 ］ very close to, can reduce Control arm ［ 3 ］ suffered moment of deflection and permanent deformation thereof during work; After adopting above-mentioned single longitudenal arm independent suspension on the vehicle, the vehicle frame shape is greatly simplified, its longeron, crossbeam all can make rectilinear form, make its compacting tool set and product all be easy to make, upper support crossbeam ［ 11 ］ but also the double as driving engine or (with) support of vehicle body, further simplify the structure of vehicle by one-object-many-purposes.

Above-mentioned have vertical type elastic element single longitudenal arm independent suspension and obtained using and producing a desired effect on contriver's design-calculated super-mini.
