Specific embodiment

Below in conjunction with accompanying drawing, specific embodiment of the present utility model is described in detail.It should be appreciated that herein Described specific embodiment is merely to illustrate and explains this utility model, is not limited to this utility model.

As depicted in figs. 1 and 2, this utility model provides a kind of automobile front axle I-beam, including upper flange 11, web 12 and Lower wing plate 13, wherein, on web 12, the length direction arranged for interval along I-beam has three elongated through holes.By in I-beam Three elongated through holes of arranged for interval along its length on web, on the one hand can mitigate the weight of car load, reduce front face area and Windage, improves the fuel economy of car load；On the other hand, compared with traditional I-beam, hollow type I-shaped of the present utility model Joist support loading capability is higher, and structural stability is more preferable.

It is emphasized that this utility model overcomes the technology prejudice that automobile I-shaped beam field exists, and (that is, structure is thicker Strong consolidation, bearing capacity is stronger), by I-beam is made engraved structure, make the bearing capacity of I-beam higher on the contrary, be better than Compact structure.

Specifically, as shown in figures 1 and 3, the upper flange 11 of this I-beam is formed with two leaf spring installed surfaces 111, edge The length direction of I-beam, three elongated through hole arranged for intervals between two leaf spring installed surfaces 111.Wherein, elongated through hole can Think rectangular opening or slotted hole.

In this utility model, three elongated through holes include interstitial hole 121 and two side openings 122, and interstitial hole 121 is located at work On the centrage 2 of word beam 1 and symmetrical with regard to centrage 2, two side openings 122 are arranged symmetrically with regard to centrage 2, in such manner, it is possible to protect The stress equalization of card I-beam axle, improves the ride comfort of running car.

In this utility model, the two ends in order to avoid interstitial hole 121 form stress concentration, as shown in Fig. 2 interstitial hole 121 every one end has connected upper fillet 1211 and lower fillet 1212, and the radius of upper fillet 1211 is more than lower fillet 1212 Radius, two fillets form the arc transition between the upper side wall of interstitial hole 121 and lower wall.

In addition, in order to avoid the two ends of side opening 122 form stress concentration, simultaneously in order to adapt to the thickness change of web 12, As shown in Fig. 2 the inner of two side openings 122 being arranged symmetrically with regard to centrage 2 has on connected the inner fillet 1221 and interior The lower fillet 1222 in end, on the inner, the radius of fillet 1221 is less than the radius of inner lower fillet 1222, is formed under side opening 122 the inner Arc transition between side wall and upper side wall；The outer end of two side holes 122 has fillet 1224 under fillet 1223 and outer end on outer end, Be formed with transition plane 1225 between fillet 1224 under fillet 1223 and outer end on outer end, on outer end the radius of fillet 1223 with outer The radius of the lower fillet 1224 in end is equal.Here, " inner " of side opening 122 refers to the one end near centrage 2, and " outer end " refers to far One end from centrage 2.

According to other side of the present utility model, provide a kind of steeraxle, as shown in figure 4, this steeraxle includes I-shaped Beam 1, knuckle 3 and stub 4, wherein, I-beam 1 and knuckle 3 can be carried out hinged, for improving steeraxle by stub 4 Ease of steering, the end of I-beam 1 is sleeved on the middle part of stub 4, and the upper ear 31 of knuckle 3 and lower ear 32 pass through needle roller respectively Bearing 5 is sleeved on the upper and lower ends of stub.Can realize in the way of using interference fit between knuckle 3 end and stub 4 Connect, by matching with stub 4 using needle bearing 5, steering drag can be reduced, improve ease of steering, can simultaneously Reduce the abrasion to stub, it is to avoid the stub looseness causing because of stub abrasion, substantially reduce in driving conditions because of stub looseness The steering shimmy leading to, improves the operating characteristics of car load, additionally, needle bearing is easily guaranteed that with the lubrication of stub, is not in Stopping up of oil channel phenomenon.

Wherein, in this utility model, stub 4 is set with thrust bearing 6, thrust bearing 6 is located at lower ear 32 and I-shaped Between beam 1.Adjust pad 7 is set with stub 4, adjust pad 7 is located between upper ear 31 and I-beam 1.Wherein, thrust bearing 6 are mainly used in bearing axial load, and adjust pad 7 is mainly used in adjusting the pretightning force of stub 4 bearing, it is to avoid due to stub 4 pine Spacious cause steering shimmy in vehicle traveling process.

According to another one aspect of the present utility model, provide a kind of automobile, this automobile includes this utility model offer Steeraxle, by the I-beam using engraved structure, mitigates the weight of car load, reduces windage, improve the fuel economy of car load.

Describe preferred implementation of the present utility model above in association with accompanying drawing in detail, but, this utility model does not limit Detail in above-mentioned embodiment, in range of the technology design of the present utility model, can be to skill of the present utility model Art scheme carries out multiple simple variant, and these simple variant belong to protection domain of the present utility model.

It is further to note that each particular technique feature described in above-mentioned specific embodiment, in not lance In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, this utility model is to each Plant possible compound mode no longer separately to illustrate.

Additionally, combination in any can also be carried out, as long as it is not disobeyed between various different embodiment of the present utility model Carry on the back thought of the present utility model, it equally should be considered as content disclosed in the utility model.
