Abstract
The utility model relates to a connecting device between vehicle components, in particular to a mounting base for a vehicle steering gear input shaft dust cover. The mounting base is connected between a steering gear casing and the dust cover and comprises a supporting plate connected with the dust cover and a connecting part fixedly connected between the supporting plate and the steering gear casing. The supporting plate is provided with an end face which is matched with the lower end of the dust cover and is in embedded connection with the lower end of the dust cover. According to the technical scheme, matched sealing performance of the dust cover and the steering gear casing can be effectively improved, the sealing effect of the dust cover is improved, and the connecting device is simple in structure.
Description
Technical field
The utility model relates to a kind of connecting device between vehicle component, relates in particular to a kind of bogie of car input shaft dust boot mount pad.
Background technology
Bogie of car input shaft dust boot is connected between deflector and body dash board conventionally, plays sealing function, with at vehicle in the process of moving, prevents the intrusion of muddy water, sandstone, meanwhile, plays the effect of isolated car external noise.Existing dust boot is general adopts single elastomeric material to manufacture, and the interference fit by with bogie of car housing and body dash board, plays sealing function.Owing to turning to input shaft housing place need to arrange oil inlet and oil return interface tube, and the parts such as mounted inside rotary valve, bearing, oil sealing, cause turn to input shaft housing and dust boot coordinate area too small, in steering procedure, be difficult for fixing, coordinate not tight, therefore,, because guard shield unbalance stress causes poor sealing phenomenon, make sealing property not good, and, due to the consideration to car load NVH, dust boot thickness is increased, poor sealing phenomenon is more obvious.In addition,, because the thrust of guard shield is provided by deflector input housing, pressure Main Function is in dust boot middle body, but dust boot is fitfull shape, and area, much larger than input shaft housing, causes dust boot and body dash board cooperation place discontinuity, causes partially sealed bad.
Utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of bogie of car input shaft dust boot mount pad that improves dust boot and steering gear housing fitted seal performance, and its actv. improves the sealing effectiveness of dust boot.
For achieving the above object, bogie of car input shaft dust boot mount pad of the present utility model, be connected between steering gear housing and dust boot, comprise the stay bearing plate being connected with dust boot and be fixed on stay bearing plate and steering gear housing between connecting portion, described stay bearing plate has and matches with dust boot lower end and embed the face area that is connected to dust boot lower end.Stay bearing plate adopts this area setting, makes deflector impose on the thrust of dust boot more even, guarantee tightr with coordinating of body dash board, thereby improve sealing effectiveness.
As to restriction of the present utility model, described connecting portion is connected with steering gear housing interference fit.
As to improvement of the present utility model, on stay bearing plate, be provided with coordinate with dust boot, restriction dust boot and stay bearing plate limiting section in relative rotation.By the limiting section of setting up, prevent relatively rotating between dust boot and stay bearing plate in steering procedure, further improved sealing effectiveness.
As the restriction to aforesaid way, described limiting section is to embed with dust boot the ellipse around boss coordinating.Structure setting to limiting section, realization prevent in steering procedure between dust boot and stay bearing plate simultaneously in relative rotation, make ellipse around boss and stay bearing plate form the structure design of boss shape, increase contacting between stay bearing plate and dust boot and coordinated area, and in conjunction with stay bearing plate, be connected the dual intrusion of having avoided the muddy water sandstone that causes in Vehicle Driving Cycle process with the embedding of dust boot.
As to improvement of the present utility model, on connecting portion, be fixed with the limiting stopper that moves axially of conflicting and coordinating with dust boot lower end.By setting up, move axially limiting stopper, limited vehicle in the process of moving because vibrations cause that dust boot, along the moving axially of connecting portion, has further improved use sealing effectiveness.
As to improvement of the present utility model, on connecting portion, be fixed with dust boot lower end and inlay the circumferential rotary spacing piece coordinating.By circumferential rotary spacing piece, further define vehicle in the process of moving because vibrations cause relatively rotating between dust boot and stay bearing plate, to improve sealing result of use.
As to restriction of the present utility model, on stay bearing plate, be provided with for steering gear input shaft, pass through and with the auxiliary section of steering gear input shaft free-running fit.By the free-running fit of auxiliary section and steering gear input shaft, when guaranteeing deflector normal operation, actv. is avoided foreign matter to fall in deflector, causing deflector clamping stagnation.
In sum, adopt as above technical scheme, can improve the sealing property that dust boot coordinates with steering gear housing by actv., improved the sealing effectiveness of dust boot, it is simple in structure.

The specific embodiment
The present embodiment relates to a kind of bogie of car input shaft dust boot mount pad, be connected between steering gear housing and dust boot, as shown in Figure 1, it comprise the stay bearing plate 2 being connected with dust boot 1 as described below and be fixed on stay bearing plate 2 and steering gear housing as described below 3 between connecting portion 4, shown in Fig. 2, stay bearing plate 2 have match with dust boot 1 lower end and embed the face area be connected to dust boot 1 lower end; The column structure that connecting portion 4 is hollow.
On stay bearing plate 2, be provided with, restriction dust boot 1 that coordinate with dust boot 1 and stay bearing plate 2 limiting section 5 in relative rotation.In the present embodiment, the ellipse around boss structure that limiting section 5 arranges for protruding the upper surface of stay bearing plate 2 is provided with the groove embedding for this ellipse around boss structure on dust boot 1, and then has realized ellipse around boss and coordinate with the embedding of dust boot 1; In addition, this boss structure and stay bearing plate 2 form one stepped, thereby limiting between dust boot 1 and stay bearing plate 2 while in relative rotation, increased the area of contact between stay bearing plate 2 and dust boot 1.
At the middle part of stay bearing plate 2, be provided with the auxiliary section 6 of a hollow, this auxiliary section 6 is for passing through for steering gear input shaft, itself and the little free-running fit setting of steering gear input shaft.
As shown in Figure 3, in use, the bogie of car input shaft dust boot mount pad that the present embodiment relates to, be connected between steering gear housing 3 and dust boot 1, wherein, steering gear housing 3 is realized and being connected by interference fit with connecting portion 4, and the edge of stay bearing plate 2 embeds in dust boot 1, with the sealing that realizes the two, is connected.In addition, be fixed with and move axially limiting stopper 7 on the outside face of connecting portion 4, this moves axially limiting stopper 7 and conflicts in the lower end of dust boot 1, realizes to dust boot the axial support along connecting portion 4, and then restriction dust boot 1 moving axially along connecting portion 4; Meanwhile, on the outside face of connecting portion 4, be fixed with circumferential rotary spacing piece 8, in the lower end of dust boot 1, be provided with the groove embedding for circumferential rotary spacing piece 8, by circumferential rotary spacing piece 8, be embedded in this groove, avoided dust boot 1 rotating relative to connecting portion 4.
