Description

Spring holder

Technical field

The utility model is related to automotive suspensions, and in particular to a kind of upper spring disk structure of front damper.

Background technology

The upper spring disk structure of traditional front damper offers among former spring holder ontology 10 as depicted in figs. 1 and 2 The former mounting hole 20 assembled with former piston rod 70, the lower section of former spring holder ontology 10 for installing former helical spring 40, upper surface with Primitive axis holds 50 contacts, and former 10 upper surface of spring holder ontology, the 20 top weldering of former mounting hole are stably mounted in order to which primitive axis is held 50 It is connected to limiting gasket 30, primitive axis, which is held, is provided with boss 60 compatible with limiting gasket 30 on 50, padded by boss 60 and limit The cooperation of circle 30 limits bearing 50 in the upper surface of former spring holder ontology 10.

Under normal conditions, the upper spring disk structure upper surface of front damper holds 50 supporting surface as primitive axis, and lower section is used for The installation of former helical spring 40, and then play a part of to be auxiliarily fixed to pillar assembly, therefore its structure size directly affects pillar sheet The weight and production cost of body.Therefore upper spring disk using the above structure is applied in fore-stock, due to the limit of upper spring disk Position washer 30 needs first to be machined out, and is then subsequently welded to above upper spring disk, not only so that unsprung mass becomes larger, reduces The comfort of vehicle, while production process is more, also increases the weight and production cost of pillar itself.

CN105782321A discloses a kind of front shock absorber of automobile rotation post, including top connection board, piston rod, work The vehicle body of cylinder and knuckle support, the top connection board and automobile is fixedly linked, one end of the piston rod and the top Connecting plate connects, and the knuckle support fixation is set in outside the working cylinder, and one end of the piston rod passes through revolving member It is rotatablely connected with the top connection board, the other end of the piston rod is fixedly connected with the working cylinder.Above-mentioned document is main Effect is to reduce pivoting friction, improves the steering reversal ability of automobile.But the upper spring disk knot that the figure two in document is shown Structure is similar to the upper spring disk structure of traditional front damper, and is not directed to defect existing for existing upper spring disk and proposes to improve Scheme.

Therefore those skilled in the art are dedicated to researching and developing that a kind of unsprung mass is lighter, and vehicle comfort is higher, produces simultaneously The upper spring disk of lower-cost front damper.

Invention content

In view of the drawbacks described above of the prior art, the utility model provides a kind of spring holder, can solve it is existing before subtract The unsprung mass that the upper spring disk of shake device is brought is big, and vehicle comfort is low, and the problem that production cost is high.

To achieve the above object, the utility model provides a kind of spring holder, including spring holder ontology, in spring holder ontology The heart is provided with mounting hole, and spring holder ontology upper surface and bearing touch, lower section are close to helical spring, spring holder ontology upper surface A circle protrusion is set up；The protrusion is abutted with the bearing.

Preferably, protuberance cross section is in the V-arrangement overturn vertically.

Further, the diameter of bearing is equal with the minimum diameter of the protrusion.

The utility model is simple in structure, and innovation is stamped and formed out protrusion on spring holder ontology, and by protrusion to bearing Radial direction limited, under the premise of ensureing original function, eliminate limiting gasket, so also eliminate primitive axis hold it is convex Platform simplifies the structure of front damper, alleviates unsprung mass, reduces vehicle production cost, improves the comfort of vehicle.

Specific implementation mode

With reference to the accompanying drawings and examples, the utility model is described in further detail：

As shown in Figs. 3-4, a kind of spring holder, including spring holder ontology 1, spring holder ontology 1 are provided centrally with mounting hole 2, 1 upper surface of spring holder ontology is contacted with bearing 3, and lower section is close to helical spring 4, and 1 upper surface of spring holder ontology has been set up One circle protrusion 5；Protrusion 5 is abutted with bearing 3, is limited to the radial direction of bearing by protrusion.

5 section of protrusion is in the V-arrangement overturn vertically, and protrusion 5 is divided into inner ring 6 and outer ring 7 on the basis of two sides of V-arrangement, interior Loop diameter（That is minimum diameter）It is equal with 3 diameter of bearing, be conducive to bearing assembly in protrusion.

When producing the utility model, only need to carry out a punch process on the basis of existing spring holder ontology can shape At protrusion, reduce the production process of upper spring disk, reduces the production cost of upper spring disk；When assembly, directly bearing 3 is filled It fits in protrusion, no longer needs to that boss is arranged on bearing 3；Then piston rod 8 is passed through into mounting hole 2 again, that is, completes assembly.This Utility model directly eliminates limiting gasket compared with existing upper spring disk, simplifies the structure of front damper, mitigates matter under spring Amount reduces vehicle production cost, improves the comfort of vehicle.
