Abstract
The invention discloses a dustproof cover for a joint of an automobile steering beam. The dustproof cover comprises a cylindrical dustproof cover body and is characterized in that a flange and an upper cover edge are arranged at the upper end of the dustproof cover body; a cover skirt is arranged at the lower end of the dustproof cover body; an annular groove step is formed through the cover skirt and the dustproof cover body; connection reinforcing ribs are arranged on the upper cover edge and the dustproof cover body to guarantee the twist-resistant strength of the dustproof cover when the steering beam rotates up and down; a groove is formed by the flange and the upper cover edge and can effectively prevent accumulated dust around a steering beam joint from falling into the dustproof cover body; an anti-rotation wedge block is arranged on the edge of the lower end of the cover skirt; dustproof washers are fixedly arranged on the groove step and the groove and made of an activated carbon sponge material, can be replaced independently and are used for preventing dust and absorbing dust entering the steering beam joint from the lower end of the dustproof cover.
Description
Technical field
The present invention relates to automobile mechanical parts technical field, be specially a kind of motor turning beam
The dust cover in joint.
Background technology
Motor turning beam, provides the drive mechanism of power, has the highest precision for motor turning
Degree and dust-proof requirement, to guarantee to turn to the transmission effect of driving joint parts, it is therefore desirable to is turning
Joint dust cover is installed additional, to prevent dust from entering the joint of steering beam between axle.
In prior art, the dust cover in motor turning beam joint the most all uses conventional height resistance to
Fatigability rubber is made as main body, and structure is substantially designed as fold-type, with satisfied different torsions
The dust-proof demand of the structure change under square, all there is poor durability, easily cause when turning to dust-proof
Cover excessive deformation and cause and rupture, lose the technical problem of dust reduction capability.The present invention designs one
Plant the dust cover in motor turning beam joint, solve the problem that above-mentioned prior art exists.
Summary of the invention
It is an object of the invention to provide the novel knot of the dust cover in a kind of motor turning beam joint
Structure design, to solve the prior art problem proposed in above-mentioned background technology.
For achieving the above object, the present invention provides following Analyzing on Building A Planning Scheme: a kind of motor turning
The dust cover in beam joint, including cylindrical dust boot body, it is characterised in that: described dust-proof
Cover body upper end is provided with the lower end of flange and upper cover edge, described dust boot body and is provided with overskirt, institute
Stating the groove rank of overskirt and described dust boot body formation annular, described upper cover edge is dust-proof with described
Cover body is provided with connection strengthening rib, to guarantee the anti-of dust cover when the upper and lower axle of steering beam rotates
Transverse strength, meanwhile, described flange forms groove with described upper cover edge, can effectively prevent from turning to
The laying dust of axle juxtra-articular falls into inside dust boot body.
Further, the lower edge of described overskirt is provided with anti-rotation voussoir, in order to prevent the present invention
Dust boot body causes dust cover unitary rotation because of the rotation of steering mechanism.
Further, described groove rank and described groove are all installed with dust washer, described anti-
Dirt packing ring is activated carbon spongy body material；Described dust washer can be individually replaced, in order to prevent also
Absorb dust cover lower end and enter the dust in steering nodal axisn.
Compared with prior art, the invention has the beneficial effects as follows: the lower notches of present invention design and skirt
Cover structure, can effectively ensure that the steering spindle upper and lower dust-proof demand in rotation process, and be not required to
Steering beam joint moment of torsion and form the distortion to dust cover, it is to avoid the fatigue of overall dust cover is subject to
Damage, be effectively increased the life-span of dust cover, the introducing design of the upper and lower dust washer of simultaneous,
Further increase the dust-proof effect of dust cover.
Accompanying drawing explanation
Fig. 1 is the structural representation of the dust cover in the present invention a kind of motor turning beam joint.
In figure: 1, dust boot body, 2, dust washer, 3, anti-rotation voussoir, 4, flange, 5,
Groove edge, 6, connection strengthening rib, 7, overskirt, 8, groove rank, 9, upper cover edge.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present invention
Case is clearly and completely described, it is clear that described embodiment is only the present invention one
Divide embodiment rather than whole embodiments.Based on the embodiment in the present invention, this area is general
The every other embodiment that logical technical staff is obtained under not making creative work premise,
Broadly fall into the scope of protection of the invention.
Referring to shown in Fig. 1, the present invention provides the dust cover in a kind of motor turning beam joint, bag
Including the dust boot body 1 of cylinder, the upper end of dust boot body 1 is provided with flange 4 and upper cover edge
9, the lower end of dust boot body 1 is provided with overskirt 7, overskirt 7 and described dust boot body 1
Forming the groove rank 8 of annular, described upper cover edge 9 is provided with to be connected with described dust boot body 1 and adds
Strong muscle 6, to guarantee the anti-buckling strength of the dust cover when the upper and lower axle of steering beam rotates, meanwhile,
Described flange 4 forms groove with described upper cover edge 9, and 5 can effectively prevent steering spindle juxtra-articular
Laying dust fall into inside dust boot body.
As the improvement of such scheme, the lower edge of overskirt 7 is provided with anti-rotation voussoir 3, in order to
Prevent dust boot body of the present invention from causing dust cover unitary rotation because of the rotation of steering mechanism.
Further, described groove rank 8 and described groove 5 are all installed with dust washer 2,
Described dust washer 2 is activated carbon spongy body material；Described dust washer 2 can be individually replaced,
The dust in steering nodal axisn is entered in order to prevent and to absorb dust cover lower end.
Provide the benefit that: the lower notches of present invention design and skirt cover structure, can effectively ensure that steering spindle
Upper and lower dust-proof demand in rotation process, and be not required to along with steering beam joint moment of torsion is formed anti-
The distortion of dust hood, it is to avoid the fatigue of overall dust cover is impaired, is effectively increased the longevity of dust cover
Life, the introducing design of the upper and lower dust washer of simultaneous, further increase the anti-of dust cover
Dirt effect.
Although an embodiment of the present invention has been shown and described, for the ordinary skill of this area
For personnel, it is possible to understand that without departing from the principles and spirit of the present invention can be to this
A little embodiments carry out multiple change, revise, replace and modification, and the scope of the present invention is by appended power
Profit requires and equivalent limits.
