Abstract

The utility model provides a front suspension thrust bearing having an oil seal, which is arranged in the front suspension of the car and the rubber support of the front suspension connected with the car body. The thrust bearing is composed of a bearing upper ring, a bearing lower ring, a roller ball, a dustproof cover, and fat and oil which is arranged among the components; the thrust bearing is also composed of an o-shaped sealing ring which is arranged between the bearing upper ring and the dustproof cover; a lip-shaped sealing ring skeleton which is arranged on the bearing lower ring, and the thrust bearing is also composed of a lip-shaped sealing ring which is arranged on the lip-shaped sealing ring skeleton and is tightly matched with the dustproof cover. The structure of the utility model makes the fat and oil of the entire thrust bearing lie in a sealing state (oil sealing); when the car is driven in a worse operating condition, the car can not be subjected or be less subjected to the intrusion of the sediment; the service life of the thrust bearing can be prolonged; the failure rate can be decreased, and the utility model has simple structure, and convenient enforcement.

Description

The front suspension thrust-bearing of band oil sealing

(1) technical field

The utility model relates to the thrust-bearing in the front suspension rubber bearing that a kind of car front suspension and vehicle body connect, and refers in particular to a kind of front suspension thrust-bearing with oil sealing.

(2) background technique

Thrust-bearing in the front suspension rubber bearing that car front suspension and vehicle body connect, referring to shown in Figure 1, Fig. 1 is a front suspension thrust-bearing key plan in use.By shown in Figure 1, thrust-bearing 10 is to be in the front suspension rubber bearing 13 of car front suspension and vehicle body connection, in front suspension, other critical piece adjoining with front suspension rubber bearing 13 has: front suspension nut 12, shock absorber piston rod 11 and upper spring dish 14 etc.Thrust-bearing 10 needs enough dustproof and anti-mud functions.

The structure of existing thrust-bearing as shown in Figure 2, generally by enclose 101 on the bearing, bearing circle 102, rolling ball 103, dust cover 107 and put at the grease between these parts 108 and form down.

If car travels under operating mode comparison harsh conditions, this thrust-bearing often because own blow-by (not oil sealing) can be subjected to the intrusion of silt, uses under this environment for a long time, and thrust-bearing bearing failure takes place easily and turns to the problem of abnormal sound.

(3) model utility content

The purpose of this utility model is the problem of bringing for the structural imperfection that solves thrust-bearing in the above-mentioned prior art, a kind of band oil sealing itself is provided, and does not change the front suspension thrust-bearing of a kind of novel band oil sealing of other component in the front suspension and matching relationship thereof.

The purpose of this utility model is achieved in that

A kind of front suspension thrust-bearing with oil sealing, be to be in the front suspension rubber bearing of car front suspension and vehicle body connection, described thrust-bearing is by circle on the bearing, circle, rolling ball, dust cover and put at the grease between these parts and form under the bearing, described thrust-bearing also comprises: an O RunddichtringO is arranged on the described bearing between circle and the dust cover; A lip-type seal ring framework is arranged at and encloses under the described bearing; A lip-type seal circle is arranged on the described lip-type seal ring framework, and closely cooperates with described dust cover.

Effect of the present utility model:

The front suspension thrust-bearing of band oil sealing of the present utility model owing to have oil seal structure, can prevent the invasion of silt in the vehicle driving effectively, therefore, can prolong the working life of thrust-bearing, reduces rate of fault; And the utility model is simple in structure, and it is convenient to implement.

For further specifying above-mentioned purpose of the present utility model, structural feature and effect, the utility model is described in detail below with reference to accompanying drawing.

(4) description of drawings

Fig. 1 is a front suspension thrust-bearing key plan in use;

Fig. 2 is the structural drawing of existing front suspension thrust-bearing;

Fig. 3 is the enforcement illustration of the front suspension thrust bearing of the utility model band oil sealing.

(5) embodiment

Below in conjunction with embodiment's accompanying drawing, the structure of the front suspension thrust-bearing of band oil sealing of the present utility model is elaborated.

Fig. 3 is the enforcement illustration of the thrust bearing of the utility model band oil sealing, and wherein circular enlarged view is the structural drawing of lip-type seal circle 6.

Simultaneously referring to front suspension thrust-bearing key plan in use shown in Figure 1.

As mentioned above, the front suspension thrust-bearing of band oil sealing of the present utility model, be in the front suspension rubber bearing of car front suspension and vehicle body connection, in front suspension, other critical piece adjoining with front suspension rubber bearing 13 has: shock absorber piston rod 11, front suspension nut 12 and upper spring dish 14 etc.

Thrust-bearing 10 of the present utility model by enclose 1 on the bearing, bearing circle 2, rolling ball 3, dust cover 7 and put at the grease between these parts 8 and form down.

Wherein, increase is provided with an O RunddichtringO 5 between circle 1 on the described bearing and dust cover 7.When thrust-bearing 10 was installed in the front suspension rubber bearing 13, O RunddichtringO 5 should closely contact (shown in Figure 1) with described front suspension nut 12.Like this, just can prevent that dust from passing through on dust cover 7 and the bearing slit pollution grease 8 between the circle 1 and front suspension nut 12 on the slit of circle 1 and the bearing.

Circle 2 increases a lip-type seal ring framework 4 is set under described bearing, lip-type seal ring framework 4 is and the angled α of vertical axis, and with bearing down circle 2 block fixing (present embodiment α is 3 °).

A lip-type seal circle 6 is set on described lip-type seal ring framework 4, lip-type seal circle 6 is that sulfuration is fixed on the lip-type seal ring framework 4, and closely cooperate with described dust cover 7, pollute grease 8 in the slit of circle 2 to avoid dust down through dust cover 7 and bearing.

O RunddichtringO 5 and lip-type seal circle 6 use rubber material, and lip-type seal ring framework 4 uses metallic material, uses stainless steel material in the present embodiment.

Parts such as the O RunddichtringO 5 that increases in the utility model, lip-type seal circle 6 and lip-type seal ring framework 4 are not changed the structure of the component of other in the front suspension in the prior art and the matching relationship between them.

The utility model is owing to increasing an O RunddichtringO 5 between circle 1 and the dust cover 7 on the bearing, circle 2 increases a lip-type seal ring framework 4 and increase a lip-type seal circle 6 between lip-type seal ring framework 4 and dust cover 7 under bearing, make grease 8 in the whole thrust-bearing 10 be in the state (oil sealing) of sealing, even car travels under operating mode comparison harsh conditions, this thrust-bearing also can not be subjected to or be subjected to less the intrusion of silt.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims the above embodiment's variation, modification.
