Description

Stabilizer for vehicle suspension

Technical field

The present invention relates to a kind of stabilizers for vehicle suspension, can be applied to the Parts mapping of motor vehicle industry Field.

Background technique

The suspension system of motor vehicles includes the stabilizer being arranged between vehicle chassis and the suspension of each wheel.These Stabilizer is usually made of columned element, is included shell in its end, is used for erection joint, usually ball-and-socket joint or scratches Property connector.

Stabilizer is the component of stable connection bar and wheel suspension.Stabilizer belongs to usually by stabiliser bar, stabilizer, suspension The kinematic chain constituted with vehicle chassis.The effect of stabilizer is the element by the stress transfer of stabiliser bar generation to wheel suspension, Vice versa, and the torque opposite with vehicle roll torque is generated in vehicle chassis, so that it is bigger lateral rigid to obtain vehicle Degree.

When vehicle started curved, the inclined centrifugal force in outside that will lead to vehicle body to the bend is generated, to generate Moment resulting from sidesway.The stabiliser bar that the suspension of wheel is attached to by way of stabilizer is then subjected to reverse, thus generation and vehicle The opposite torque of moment resulting from sidesway.

As described above, the effect of stabilizer is the stress transfer that will be generated by stabiliser bar to wheel suspension, vice versa.This A element includes two connectors by longitudinal ontology attachment.The connector can be ball-and-socket joint or flexible coupling.One of them Connector is next attached to stabilizer or torque rod, and another connector is attached to the damper of vehicle, and can also be anchored to is not In other any elements of the suspension of damper, such as cantilever.

Stabilizer is usually made of metal or polymer body, and in end, there are two the centres of motion for tool, they are to be located at institute State the rotation center of the connector of end.These connectors can be ball-and-socket joint or flexible coupling.

If these connectors are ball-and-socket joints, intermediate member is arranged between the ball-and-socket joint and the main body of referred to as seat, Its function, which is to ensure that, is located in ball-and-socket joint in the centre of motion, allows stress being transmitted to main body from ball-and-socket joint, and Ball-and-socket joint is allowed to rotate relative to main body.These are attached in main body structure-integratedly, therefore in ball-and-socket joint with more than There is relative motion between the other component of description.

The ball-and-socket joint, which has, to be generated three rotary freedoms and is attached to anti-roll bar assembly on stabiliser bar or motor-driven Function on the damper of vehicle.Other than the two functions, there are also third functions, that is, ensures not leak in connector. This functionality is also present in the main body of stabilizer, because dust seal or bellows are anchored at the two by ring In component.

In the case where considering has the flexible coupling of 6 freedom degrees, connector is integrally attached to stabilization in one end In the main body of device, and it is connected on stabiliser bar or on the damper of motor vehicles in the other end.

Different types of stabilizer has different configurations according to each specific application in the market.Lead between these elements Often with there are a series of common requirements, especially there is specific rigidity, weight as small as possible allows quick group as far as possible It is filled with and cost as small as possible.

The characteristics of steel stabilizer is that weight is big, poor corrosion resistance, it is necessary to apply coating to main body.This stabilizer it is excellent Point is that its rigidity is very high.

In addition, the characteristics of aluminum stabilizer is that weight ratio stabilizer above-mentioned is light, but rigidity is also smaller.

Finally, plastics stabilizer, its main feature is that weight is lighter, it is more economical.However, plastics stabilizer needs bigger volume There could be the rigidity being equal with stabilizer mentioned above.

Currently, having used various methods to obtain these stabilizers.These methods are by the type of stabilizer, material and design It is required that determine.In the sense that, forming being attached to each other for the main component of the main body of stabilizer is that decision is obtained steady Determine the production cost of device and an importance of intensity, this be one can be in current steady device and for obtaining these stabilizations The aspect optimized during device.

Summary of the invention

The present invention relates to stabilizers as defined in claim 1.

Stabilizer of the invention is stave, and in its end, there are two ball-and-socket joints for tool.The element has two in end A motor point, the two motor points are the centers of connector.The line for connecting two centres of motion is referred to as " longitudinal axis ".It should be understood that The longitudinal axis is overlapped with the principal axis of inertia of the middle section of main body, so that traction compressive load is uniformly distributed in entire section.

As described above in greater detail, it once having been described that the present invention, is formed surely this invention address that improving and optimizing Determine the attachment of the component of the main body of device, this allows to reduce production cost, and maintains the mechanical performance of stabilizer simultaneously.

Stabilizer proposed by the present invention includes the longitudinal polymer main body with metal framework, and there are two metal framework tools End and a central section have hole in each end, accommodate ball-and-socket joint in the hole.Frame is had by two The metal parts of cutout portion is constituted, the two metal parts are positioned relative to each other in their open side.

According to the present invention, each component includes that part is pulled out at least one deep-draw, which, which pulls out, is partially toward the open side, So that opposite component is supported on the deep-draw and pulls out part above and be attached at wherein by welding.

For example, the other modes of the attachment about the component for forming central body, such as attached about being carried out by rivet It connects, the present invention has the advantages that reduce the quantity of component and can prevent the risk that rivet is lost and bring stabilizer ruptures. Further, since part is less, the weight of entire stabilizer reduces therewith, while having the mechanical performance for keeping even increasing attachment Ability.

Of the invention other accidental are defined in the dependent claims.

It is expected that the central section of each component includes being oppositely disposed at every side and towards the two of the open side The possibility of a lug.In this case, the end includes edge, so that two opposite components are in addition to being supported on State deep-draw pull out part it is upper other than, be also supported on the lug and the edge.

It is also contemplated that welded part is embedded in the main body of cladding molding, the main body of cladding molding exists Outside coats above-mentioned welded component, and fills the inner space limited by described two opposite metal parts.

According to this embodiment, it should be pointed out that principal advantages of the invention, that is, when using rivet, welding will not be from component Profile it is prominent, this, which to coat moulding process, becomes easier to, and due to not no being not intended to for generating due to rivet outstanding Abrasion, which increase the durabilities of stabilizer.

The second aspect of the present invention is related to a kind of method for obtaining the stabiliser bar as described above for vehicle suspension.

According to the present invention, this method includes with next stage or step:

Two metal parts are obtained by mechanical compression molding, each component tool is there are two end and including at least one The central section of part is pulled out in deep-draw, and each end has a hole,

~-component is positioned relative to each other,

Two components are welded on opposite deep-draw to pull out in part, and

Component is embedded into the main body of cladding molding, the main body of the cladding molding carries out the component in outside Coating, and fill the inner space limited by two opposite metal parts.
