Abstract
The utility model relates to relates to the valve assembly of the core part of an automobile power steering valve, particularly to a valve with an over-current edge in composite shape. The valve comprises a valve sleeve (1) and a valve core (2), wherein the over-current edge of the valve core (2) integrates the shapes of a linear section (3.1) and an eccentric arc section (3.2). By adopting the change of the shape of the over-current edge, an over-current section changes slowly. When a steering device diverts, high-pressure hydraulic current is closed slowly through the over-current edge of the valve core, and hydraulic fluctuation noise caused by rapid fluctuation of the high-pressure hydraulic current is eliminated. The valve with novel concept and reliable operation solves the problem that hydraulic fluctuation noise is caused when the steering device diverts on the basis that no other structure and no property of the steering device are changed. The valve can be widely popularized and applied for all automobile production businesses.
Description
Affiliated technical field
The utility model relates to a kind of core component valve assembly of automobile power steering valve, the valve of especially compound overcurrent limit shape.
Background technique
Valve assembly is the core component of automobile hydraulic power steering device, existing valve assembly is to adopt straightway overcurrent limit, when commutator turns to, relative variation takes place with the angle position of valve pocket in spool, relative variation has also taken place with the keyway position of valve pocket in the oil groove of spool, it is opened by the overcurrent limit on one side, another side overcurrent frontier juncture is closed, pass through in the pass closed procedure on overcurrent limit in flow of pressurized, cross section, overcurrent limit linearly changes, so flow of pressurized rapid change and cause that high pressure liquid baric flow fluctuation noise is bigger in closing closed procedure.Because passenger car is to the requirement height of hydraulic pressure noise, the overcurrent limit shape of switching valve is anxious to be solved.
According to retrieval, the domestic patent application that the valve of compound overcurrent limit shape is not arranged as yet.
Summary of the invention
At the deficiency of above-mentioned existence, the utility model provides a kind of valve assembly that straightway overcurrent limit is a compound overcurrent limit shape that changes, eliminate commutator about the hydraulic pressure fluctuation noise that occurs when turning to.
The technological scheme that its technical problem that solves the utility model adopts is: as shown in Figure 1 and Figure 2, the valve of this compound overcurrent limit shape comprises valve pocket (1), spool (2), described spool (2), straightway (3.1) and the compound shape of eccentric circle segmental arc (3.2) are adopted in its overcurrent limit; Described overcurrent limit (3) is straightway (3.1) and eccentric circle segmental arc (3.2) compound shape, and overflow section slowly dwindles, and high-pressure and hydraulic stream is slowly closed by the overcurrent limit.
The beneficial effects of the utility model are: novel, reliable operation does not change the noise problem that solves commutator hydraulic pressure fluctuation when turning on the basis of other any structures of commutator, any performance, improves the passenger car quality index.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is I of the present utility model portion enlarged view---an overcurrent limit shape enlarged view.
The utility model is described in further detail to utilize drawings and Examples.
Embodiment
The core component of automobile hydraulic steering device---valve assembly comprises valve pocket (1) and spool (2), and its spool (2) changes existing straightway overcurrent limit into straightway (3.1) and eccentric circle segmental arc (3.2) combined compound shape overcurrent limit.Rotational valve core, relative variation takes place with the angle position of valve pocket in spool, it is opened by the overcurrent limit on one side, another side overcurrent frontier juncture is closed, owing to adopt the compound overcurrent limit shape of eccentric circle segmental arc and straightway combination, overflow section changes mitigation, therefore pass through in the pass closed procedure on overcurrent limit (3) in flow of pressurized, flow of pressurized is slowly closed, and has eliminated that flow of pressurized is closed rapid change in the closed procedure and the hydraulic pressure fluctuation noise that causes improves the passenger car quality index.
Claims (2)
1. the valve of a compound overcurrent limit shape comprises valve pocket (1), spool (2), it is characterized in that: the compound shape of straightway (3.1) and eccentric circle segmental arc (3.2) is adopted on described spool (2) overcurrent limit.
2. the valve of compound overcurrent according to claim 1 limit shape is characterized in that: described overcurrent limit (3) is straightway (3.1) and eccentric circle segmental arc (3.2) compound shape, and overflow section slowly dwindles, and high-pressure and hydraulic stream is slowly closed by the overcurrent limit.
