Abstract
The utility model discloses a magnesium alloy steering wheel which comprises a steering wheel framework (2) and a foaming body (1) arranged outside the steering wheel framework (2), wherein the steering wheel framework (2) is composed of a circular disc (3) and a framework (4); and a steel ring (5) is embedded and cast in the circular disc (3). The characteristic of the light weight of a magnesium alloy is used by the magnesium alloy steering wheel, and the steel ring (5) is embedded and cast in the circular disc (3), so that the rotary inertia is increased; the rotary inertia is increased, so that the performance of steering and reversing an automobile is improved, and the manipulation performance of the automobile is improved.
Description
Technical field
The present invention relates to a kind of bearing circle, particularly a kind of magnesium alloy bearing circle.
Background technology
Magnesium metal and alloy thereof are that the lightest applicable structural metallic materials is gone up in industry at present; Proportion approximately is 2/3 of aluminium; Be 1/4 of iron, it has high specific strength, stiffness-to-density ratio, permeability of heat, machinable property and returnability, advantages such as dimensionally stable; " green " material of construction that is called as 21 century is widely used in strength of material requirement height and lightweight field.
In recent years, along with the raising of energy savings and environmental protection requirement, the lightweight of automobile makes magnesium alloy obtain increasingly extensive application.Especially what deserves to be mentioned is that magnesium and magnesium alloy have good cushioning performance, make them in many application, have the ability of significant reduction vibration and noise.Bearing circle is the colyliform device of the manipulation travel direction of automobile, steamer, aircraft etc., and magnesium alloy becomes the desirable manufactured materials of vehicle steering.
The rotor inertia of bearing circle is important parameters very in the automotive steering design, and it is to the particularly return performance that turns to of vehicle, and the NVH performance all has bigger influence.Steering system is around the rotor inertia I of stub

The utility model content
The utility model is to be solved to provide a kind of rigidity that does not alleviate bearing circle, can increase rotor inertia, labour-saving bearing circle.
In order to solve above-mentioned technical matters, the technical scheme of the utility model is: a kind of magnesium alloy bearing circle, comprise the foaming body that frame of handwheel and frame of handwheel are outer, and said frame of handwheel is made up of disk and skeleton, the embedded steel loop that is cast with of said disk.
Said steel loop is divided into multistage, and its even embedding casting is in disk.The size of steel loop is confirmed according to the disk track and the design-calculated rotor inertia of bearing circle.
The utility model is provided with steel loop between disk and foaming body when having utilized the lightweight characteristics of magnesium alloy, increased rotor inertia.The increase of rotor inertia has improved wheel steering and has returned positive performance, has improved the operability of automobile.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the utility model foaming body structural representation.
Fig. 2 is the utility model frame of handwheel structural representation.
The specific embodiment
Like Fig. 1, shown in 2, the magnesium alloy bearing circle comprises the foaming body 1 outside frame of handwheel 2 and the frame of handwheel 2, and foaming body 1 is to be fixed on the frame of handwheel 2 through foam process.Frame of handwheel 2 is fixed in the foaming machine during production, and expanded material generates in foaming machine.
Said frame of handwheel 2 is made up of disk 3 and skeleton 4, disk 3 rotation that is used to shake hands, and skeleton 4 then plays the effect of support disk 3, and is connected with miscellaneous part, on the skeleton 4 air bag etc. can be set.
Though magnesium alloy light weight; But occasion in the bearing circle rotation; Rotor inertia that need be certain; Obviously, the pros and cons of the magnesium alloy of light weight just display: though the magnesium alloy bearing circle of light weight has reduced the overall weight of automobile, be unfavorable for bearing circle raising wheel steering return positive performance.
In order to satisfy the rotor inertia requirement of bearing circle in the automotive steering design, the said disk 3 embedded steel loops 5 that are cast with are with the rotor inertia of actv. increase magnesium alloy bearing circle.
Said steel loop 5 adds when frame of handwheel 2 embeddings are cast, and can guarantee the fastness that steel loop 5 is fixed like this.
Said steel loop 5 can adopt integral type, also can adopt sectional type, generally adopts sectional type, is about to said steel loop 5 and is divided into multistage, and every section even embedding casting is on disk 3.
The foregoing description limits the utility model never in any form, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in the protection domain of the utility model.
Claims (2)
1. a magnesium alloy bearing circle comprises the foaming body (1) that frame of handwheel (2) and frame of handwheel (2) are outer, and said frame of handwheel (2) is made up of disk (3) and skeleton (4), it is characterized in that: the embedded steel loop (5) that is cast with of said disk (3).
2. magnesium alloy bearing circle according to claim 1 is characterized in that: said steel loop (5) is a multistage, and its even embedding casting is in disk (3).
