Example be shown in the accompanying drawings, in which the same or similar labels are throughly indicated same or similar element or with identical
Or the element of similar functions.The embodiments described below with reference to the accompanying drawings are exemplary, is only used for explaining the present invention, without
It can be construed to limitation of the present invention.
It should be noted that the orientation term such as left, center, right in truth example of the present invention, upper and lower, is only relatively general each other
It reads or be to refer to the normal operating condition of product, and should not be regarded as restrictive.
A kind of rack device of wear compensation of automobile steering device, including shell 8, the interior cunning for being equipped with strip of the shell 8
Dynamic chamber is equipped with plug screw 6, C-shaped ring 4, head cover 3, flexible sheet 2 and jacking block 1 from the outer end of the sliding cavity to inner end successively, described
Plug screw 6 is fixedly connected with the first sliding cavity wall, and fluted, the groove is opened up on the inner end end face of the plug screw 6
Bottom surface be male cone (strobilus masculinus) 6-1, c-type clamp spring 5, the inner face of the C-shaped ring 4 and institute are installed on the excircle of the C-shaped ring 4
Male cone (strobilus masculinus) 6-1 is stated to be bonded and be slidably matched with the male cone (strobilus masculinus) 6-1；The head cover 3 is connected on the outer end face of the C-shaped ring 4,
The both ends of the flexible sheet 2 are abutted with the jacking block 1 and head cover 3 respectively, and the outer end of the jacking block 1, which is used to fix with rack, to be connected
It connects, specifically, being equipped with rack storage tank in the outer end end face of the jacking block 1, the rack is fixed in the rack storage tank.
Wherein, the head cover 3 is located in the groove and is slidably matched with the groove, the jacking block 1 and the sliding
Chamber is slidably matched；It is installed with baffle ring 3-1, the baffle ring 3-1 in the outer end of 3 excircle of the head cover and is used to work as the cunning of the head cover 3
Block is on the inner face of the plug screw 6 when entering the groove；It is equipped with slide bar 6-4 at the middle part of the male cone (strobilus masculinus) 6-1, described
The middle part of head cover 3 is equipped with sliding slot, and the sliding slot is slidably matched with the slide bar 6-4.
In addition, the through-hole 6-3 passed through for bolt 7 is provided on 6 bottom surface of the plug screw, through-hole 6-3 and the elastic group
The C-shaped ring 4 of part and the opening of the c-type clamp spring 5 are in line in the axial direction, can first pass through in the through-hole 6-3 bolt 7 and be stuck in
The opening of the C-shaped ring 4 and the c-type clamp spring 5 so that after the endoporus of elastic parts becomes larger, elastic parts is sleeved on plug screw 6
Axis 6-4 on, by elastic parts be mounted on plug screw 6 groove in, then pull out the bolt 7, complete the installation of elastic parts,
Elastic parts, that is, C-shaped ring 4 and c-type clamp spring 5.
The operation principle of the present invention：Since c-type clamp spring 5 has the function to contract so that c-type clamp spring 5 and the c-type
The elastic parts that ring 4 is constituted has the power to contract, and after gap becomes larger due to abrasion for gear 9 and rack 10, C-shaped ring 4 is in C
To contract under the action of type clamp spring 5, since the C-shaped ring 4 and the groove floor of the plug screw 6 cooperate for two to institute
The inclined inclined-plane in gear direction is stated, so in C-shaped ring 4 in inside contraction process, is axially generated to gear 9 and tooth in C-shaped ring 4
The movement that 10 direction of item compresses, it is thus mobile that the sliding of head cover 3 is pushed to compress flexible sheet 2 and jacking block 1.In being equipped on head cover 3
Cardiac prominence rises, and when 2 original state of flexible sheet is flat, makes flexible sheet when on the central protuberance top to flexible sheet 2 of head cover 3
2 heave, and form axial force and compress briquetting 1, briquetting 1 pushes rack 10 close to gear 9, when the axial force and C of the generation of flexible sheet 2
After type ring 4 shrinks the axial force balance of generation, the movement of C-shaped ring 4 stops, and gear 9 is with rack 10 because the gap of abrasion generation is by more
It mends.To solve the problems, such as that the noise brought due to gear 9 and the abrasion of rack 10 is big.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
