Abstract
The utility model discloses a dustproof cover of a steering gear; the dustproof cover comprises a dustproof cover main body; a clamping ring is arranged at an opening of the upper end of the dustproof cover main body; a hoop is arranged at the lower end of the dustproof cover main body; the clamping ring is clamped in a front wallboard and is in interference fit with the front wallboard; and the lower end of the dustproof cover main body is tightly connected with the steering gear by the hoop. The dustproof cover of the steering gear, disclosed by the utility model, can be closely combined with the steering gear and the front wallboard, so that a sealing effect and a waterproof effect at the matched part of the steering gear and the front wallboard are improved.
Description
Technical field
The utility model relates to the parts of automobile, relates to a kind of deflector dust boot in particular.
Background technology
The deflector dust boot is to be used for deflector band rod assembly and body front panel bonded assembly part, is to be used for carrying out body front panel to be connected transition with deflector band rod assembly.The deflector dust boot is the sealing property that is used for guaranteeing deflector and steering column junction, and the quality of its sealing property is related to the NVH performance of car load.
Existing deflector dust boot is integrated in the input end of deflector, is made up of Plastic Parts and the Rubber Parts that is connected on the Plastic Parts, and Plastic Parts directly is fixed on the housing of deflector input end, is connected with body front panel through Rubber Parts.The shortcoming of existing deflector dust boot is: Plastic Parts is connected with being connected to of deflector is hard, and sealing effectiveness is bad, and waterproof effect is also bad relatively.Sealing that this deflector dust boot and front panel junction lean on the parts assembling to guarantee on the dust boot fully and front panel is fitted has the risk that produces relative motion reduction sealing property under limiting condition; Existing dust boot is that Plastic Parts and Rubber Parts are formed simultaneously, has increased the connection seal request of part itself.
Summary of the invention
The purpose of the utility model provides a kind of deflector dust boot, and it can be combined closely with deflector and front panel, and then improves the sealing effectiveness and the waterproof effect of deflector and front panel cooperation place.
The said deflector dust boot of the utility model comprises dust boot body, and the opening part in the upper end of dust boot body is provided with snap ring, is provided with clip in the lower end of dust boot body, and said snap ring is connected in the front panel, with the front panel interference fit; The lower end of dust boot body is fastenedly connected through clip and deflector.
Further, the inside face of the lower end of said dust boot body is provided with two ring-type convex tendons, makes clip when fastening, and the lower end of dust boot body and the sealing property of deflector are strengthened, and have better waterproof effect.
Further, the opening part of the upper end of said dust boot body is provided with two circle rubber limits, makes dust boot inboard rubber limit, inefficacy back, rubber limit, the outside under limiting condition can guarantee good operation sealing, waterproof effect equally.
Further, be fixed with shell fragment on the said snap ring, when said snap ring was connected on the front panel, said shell fragment was compressed, and this shell fragment plays pressuring action to the opening of the upper end of dust boot body, has further improved the leak tightness of this dust boot.
Further, the middle part of said dust boot body is a bellows segment, and this bellows segment has retractility, has played the effect of excessive buffering, has prevented stressed the pullling in dust boot two ends and sealing effectiveness is exerted an influence.
The said deflector dust boot of the utility model, its upper end is connected in the front panel through snap ring, with the front panel interference fit; Its lower end is fastenedly connected through clip and deflector, has improved the sealing effectiveness of deflector and front panel cooperation place preferably, has improved the NVH level of car load.

Among the figure: 1, dust boot body, 2, bellows segment, 3, snap ring, 4, the rubber limit, 5, shell fragment, 6, the ring-type convex tendon, 7, clip, 8, Rubber Parts, 9, Plastic Parts.
The specific embodiment
In order further to explain the technical scheme of the utility model, come in conjunction with the drawings below the utility model is set forth in detail.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, this deflector dust boot comprises dust boot body 1; Dust boot body 1 adopts elastomeric material to process, and the opening part in the upper end of dust boot body 1 is provided with two circle rubber limits 4, and snap ring 3 is embedded in the opening part of the upper end of dust boot body 1; Riveted joint has a shell fragment 5 on the said snap ring, and the outside face in the lower end of dust boot body is provided with clip 7, and the lower end inside face of dust boot body 1 is provided with two ring-type convex tendons 6; Said snap ring 3 is connected in the front panel; With the front panel interference fit, the shell fragment 5 that is riveted on the snap ring 3 is compressed, and the opening on the dust boot body is compressed; The lower end of dust boot body is fastenedly connected through clip 7 and deflector.The middle part of said dust boot body is a bellows segment 2, and this bellows segment 2 has retractility.
Existing deflector dust boot is as shown in Figure 5; Existing deflector dust boot is integrated in the input end of deflector; Be made up of Plastic Parts 9 and the Rubber Parts 8 that is connected on the Plastic Parts, Plastic Parts 9 directly is fixed on the housing of deflector input end, is connected with body front panel through Rubber Parts 8.Plastic Parts 9 is connected with being connected to of deflector is hard, and sealing effectiveness is bad, and waterproof effect is also bad relatively.Sealing that this deflector dust boot and front panel junction lean on the parts assembling to guarantee on the dust boot fully and front panel is fitted has the risk that produces relative motion reduction sealing property under limiting condition; Existing dust boot is that Plastic Parts and Rubber Parts are formed simultaneously, has increased the connection seal request of part itself.
