Abstract
The utility model discloses a dustproof cover assembly relates to auto -parts manufacturing technical field, the support section of thick bamboo of an arc guide block is equipped with including the bottom at least, support the barrel casing dress on the steering gear input shaft, support a section of thick bamboo in the top put to one side with the car before the bolster be connected of bounding wall, the bolster is EPT rubber, a support section of thick bamboo is the circumference distribution in the bottom have a plurality of jack catchs, works as it establishes through the foam -rubber cushion snare to support a section of thick bamboo when the step of steering gear input shaft lower part is epaxial, the arc guide block with the excircle clearance fit of step axle, it is a plurality of the jack catch with the lower extreme facial features joint of step axle. Compared with the prior art, rotating appears in the cooperation that present steering gear dust cover and steering gear input shaft can be solved to it easily, results in sponge packing ring and steering gear input shaft to appear interfering and result in the friction problem of abnormal sound to appear.
Description
Technical field
This utility model relates to auto parts machinery and manufactures technical field, a kind of dust cover assembly for steering gear.
Background technology
Steering gear is the automobile most important part for turning function, is also the important guarantee of ride safety of automobile, and steering gear in use, needs to use dust cover that it is carried out sound-insulating dust-proof.Existing a kind of steering gear dust cover as shown in Figure 1, this steering gear dust cover includes support tube 102 and the tilting bolster at support tube 102 top, this bolster is sponge foaming body 101, sponge foaming body 101 is by outside the sheathed support tube of sponge washer 103 102, sponge washer 103 is connected with automobile dash board, be provided with bottom support tube 102 and the arcuate guide block of steering gear Step Shaft matched in clearance, during use directly by this dust cover bottom cover on the power shaft of steering gear.This steering gear dust cover occur the problem that 1, in use because the limitation of sponge foaming body material causes soundproof effect poor；2, the decrement of sponge washer controls difficulty, makes sponge foaming body can not fit closely with front panel, the problem easily occurring sealing difference；3, support tube is only by guide pad and the steering gear step surface matched in clearance of its underpart, rotation phenomenon easily occurs, causes sponge washer and steering gear input shaft to occur that interference causes friction abnormal sound occur.
Utility model content
The purpose of this utility model is to provide a kind of dust cover assembly, and it can solve existing steering gear dust cover easily occurred rotating with coordinating of steering gear input shaft, caused sponge washer and steering gear input shaft to occur interfering the problem that causing rubs abnormal sound occurs.
In order to solve the problems referred to above, the technical solution adopted in the utility model is: this dust cover assembly includes the bottom support tube at least provided with one piece of arcuate guide block, described support tube is sleeved on steering gear input shaft, described support tube is tilting in top the bolster being connected with automobile dash board, and described bolster is ethylene propylene diene rubber；Described support tube is circumferentially distributed multiple claw in bottom, when described support tube is set on the Step Shaft of described steering gear input shaft bottom by sponge washer, the cylindrical matched in clearance of described arcuate guide block and described Step Shaft, the lower surface phase clamping of multiple described claws and described Step Shaft.
Owing to have employed technique scheme, this utility model compared with prior art has the advantages that
1, ethylene propylene diene rubber has superior acoustic anti-dust performance, and decrement can preferably control at about 2mm, with front panel laminating closely, has good sound-insulating dust-proof function；2, dust cover lower end is designed with guide pad and claw coordinates with steering gear, during assembling, only need to be directed to block and catch on steering gear step surface facing to steering gear input shaft end draw-in groove down straightening to claw, not only can ensure that dust cover assembly will not rotate but also time saving and energy saving；3, using this dust cover assembly, can improve assembling difficulty, reduce work hours 25S, and parts assembly qualified rate improves to 95%, and car load leakage rate is reduced to 156SCFM by 200, promotes car load NVH quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing steering gear dust cover.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the sectional view at Fig. 2 A-A.
Fig. 4 is scheme of installation of the present utility model.
Detailed description of the invention
The utility model is described in further detail for embodiment below in conjunction with the accompanying drawings:
Dust cover assembly as shown in Figure 2, Figure 3 and Figure 4 includes that bottom is provided with the support tube 2 of one piece of arcuate guide block 2-1, and support tube 2 is sleeved on the Step Shaft 4-1 of steering gear input shaft 4 bottom through steering gear input shaft 4 and by sponge washer 3；Support tube 2 is tilting in top is set with the bolster being connected with automobile dash board, and the bolster of the present embodiment is ethylene propylene diene rubber 1；Support tube 2 has been circularly and evenly distributed in bottom three claw 2-2, when support tube 2 is sleeved on the Step Shaft 4-1 of steering gear input shaft 4 bottom by sponge washer 3, the cylindrical matched in clearance of the arcuate guide block 2-1 and Step Shaft 4-1 of support tube 2, the lower surface phase clamping of three claw 2-2 and Step Shaft 4-1.
During assembling, only not only need to can ensure that dust cover assembly will not rotate but also time saving and energy saving by arcuate guide block 2-1 facing to the Step Shaft 4-1 cylindrical down straightening below steering gear input shaft to the lower surface phase clamping of claw 2-2 and Step Shaft 4-1.
