Abstract
The utility model discloses a gear rack type automobile steering engine rack locating mechanism, which comprises a supporting press block part, a rack liner assembly and a rack bearing. The rack locating mechanism is characterized in that an auxiliary support, namely the rack bearing, is added on a rack of a steering engine. The rack locating mechanism has the advantages that 1 mechanical abnormal sound between gear rack transmission pairs can be effectively avoided; 2 the rack bearing can provide the rack with a support so as to control meshing gap between gear racks when deflection deformation of the rack is larger, thereby effectively avoiding abnormal rapid abrasion of the supporting press block; 3 an existing mechanism is slightly changed so that the rack locating mechanism is suitable for large-scale promotion and applies to gear rack type steering engines of all types; and 4 the rack locating mechanism is simple in structure and low in manufacture cost.
Description
Technical field
The utility model relates to automobile steering system, particularly a kind of pinion and-rack automobile steering device tooth bar detent mechanism.
Background technology
The quality of steering swivel system has determined the driving of vehicle, and in current society, automobile has been come into huge numbers of families, and the driver comfort of vehicle also more and more obtains paying attention to.
In the prior art, rack and pinion steering machine tooth bar detent mechanism comprises the rack bush assembly and supports the briquetting part.In the car load driving process when wheel is subjected to impacting, because between steering box tie-rod ball end center-point and the rack-and-gear point of engagement distance length be that the acting force arm of impulsive force is longer, the effect of power can make tooth bar produce a certain amount of winding degree distortion, this winding degree distortion causes having produced the gap between the rack-and-gear transmission, this gap has caused existing between the rack-and-gear Meshing Pair slides and impact, thereby cause the steering box abnormal sound to lose efficacy, influenced the traveling comfort of driving.And when tooth bar produces the winding degree distortion, between the tooth bar calcaneus branches support briquetting is improper contact condition, can cause the heel and toe wear that supports briquetting, and above-mentioned 2 can form a vicious circle, finally cause the gap between the rack-and-gear Meshing Pair to increase rapidly, so that abnormal sound lost efficacy.
Detent mechanism of the prior art can't be avoided between the rack-and-gear transmission also can't avoiding supporting the improper quick wearing and tearing of briquetting effectively because of sliding and impacting the mechanical abnormal sound that is produced effectively.Provide a kind of later-model detent mechanism, to avoid between the rack-and-gear transmission because of sliding and impacting mechanical abnormal sound that is produced and the improper quick wearing and tearing of supporting briquetting.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of pinion and-rack automobile steering device tooth bar detent mechanism, to avoid between the rack-and-gear transmission because of sliding and impacting mechanical abnormal sound that is produced and the improper quick wearing and tearing of supporting briquetting.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of pinion and-rack automobile steering device tooth bar detent mechanism, comprise and support briquetting part, rack bush assembly, steering box housing, it is characterized in that: increased the tooth bar bearing in the described steering box housing, support the steering rack in the rack bush assembly, be that steering rack has increased a supplemental support, thereby realized the purpose of back lash between the pinion tooth bar.
The gap width of the steering rack in described tooth bar bearing and the rack bush assembly is less than or equal to 0.6 millimeter.
Described tooth bar bearing is for being pressed into riveted and fixed behind the steering box housing.
A kind of pinion and-rack automobile steering device tooth bar detent mechanism, this mechanism has the following advantages: 1, can effectively avoid the mechanical abnormal sound between the rack-and-gear transmission; 2, when the winding degree deflection of tooth bar was big, the tooth bar bearing can be given support of tooth bar, and the back lash between the pinion tooth bar is worth, and avoids supporting the improper quick worn-down purpose of briquetting to reach; 3, less to the change of original mechanism, the rack and pinion steering machine that promptly is applicable to all models suitable for large-scale promotion; 4, simple in structure, productive costs is lower.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is the support briquetting part-structure scheme drawing of a kind of pinion and-rack automobile steering device of the utility model tooth bar detent mechanism;
Fig. 2 is the rack bush assembly scheme drawing of a kind of pinion and-rack automobile steering device of the utility model tooth bar detent mechanism;
Fig. 3 is the tooth bar bearing scheme drawing of a kind of pinion and-rack automobile steering device of the utility model tooth bar detent mechanism;
Fig. 4 is the tooth bar bearing partial schematic diagram of a kind of pinion and-rack automobile steering device of the utility model tooth bar detent mechanism;
In Fig. 1-4,1, support the briquetting part; 2, rack bush assembly; 3, tooth bar bearing; 4, steering box housing; 5, steering rack.
The specific embodiment
Shown in Fig. 1-4, the utility model comprises: support briquetting part 1, rack bush assembly 2, tooth bar bearing 3, steering box housing 4, steering rack 5, compare original design, steering rack has increased a supplemental support, thereby has realized the purpose of back lash between the pinion tooth bar.
Tooth bar bearing 3 with the fit system of steering rack 5 is: less free-running fit.The maximum clearance value is less than or equal to 0.6 millimeter.The big I of concrete gap width is according to its technological ability decision.
At first steering box is assembled into little assembly during assembling, tooth bar bearing 3 is for being pressed into steering box housing 4 back riveted and fixed.
The utility model has increased tooth bar bearing 3 because of the left end at steering box housing 4, and the fit system of this tooth bar bearing 3 and tooth bar is less free-running fit, therefore when the winding degree deflection of tooth bar greatly the time, tooth bar bearing 3 can be given support of tooth bar, thereby has realized the purpose of back lash value between the pinion tooth bar.Drawing when the back lash value between the rack-and-gear during less than 0.25 millimeter according to great number tested data, is can not produce mechanical abnormal sound.
Meanwhile, the utility model supports the improper quick wear problems of briquetting part because of having controlled the back lash value between the rack-and-gear effectively so solved original design effectively.
Test figures shows: the incidence of abnormal sound is far smaller than the steering box that has mechanism now to use steering box zero kilometer of the present utility model to reach after sale, at last after passing through fatigue test to steering box, every technical index of steering box all meets the requirements, and adopts the steering box of new mechanism of the present invention to finish the examination of client road simultaneously; And entrucking in batches, prove that this scheme meets operating needs fully.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious specific implementation of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
