Abstract
The utility model discloses a clearance adjusting and locking mechanism for a gear and rack hydraulic steering machine. The clearance adjusting and locking mechanism comprises a shell body and an adjusting pressing block used for adjusting clearance between a gear and a rack, wherein one end of the adjusting pressing block extends into the shell body, and the end surface of the other end of the adjusting pressing block is provided with a connecting groove connected with a clearance adjusting wrench; and the end part of one end, provided with the connecting groove, of the adjusting pressing block is riveted with the shell body. The clearance adjusting and locking mechanism for the gear and rack hydraulic steering machine reduces parts such as a locking nut and a torque locking wrench, reduces the cost, requires small installation space, improves the assembly matchability, avoids the failure mode caused by the loosening of a locking nut, and improves the reliability of the assembly.
Description
Technical field
The utility model relates to gear rack type steering engine, is specifically related to gear rack fluid-link steering machine gap and adjusts locking mechanism.
Background technique
At present, be applied in the gap locking mechanism in Gear Hydraulic Steering Rack Rod, mainly by briquetting plug and locking nut, formed; Briquetting plug connects adjusts handle, adjusts handle and changes rack meshing clearance by adjusting briquetting plug, and then locking nut is locked at briquetting plug on housing.Locking mechanism is adjusted in this gap, adjusts behind gear rack gap, need to use torque spanner upper locking nut beyond the Great Wall at briquetting, and operation is comparatively complicated, and cost is high; Another locking nut need take up space, and the required installing space of steering box is large, and that has reduced steering box assembly can matching; Locking nut easily gets loose simultaneously, has reduced the reliability of steering box assembly.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, takes up space little, and locking mechanism is adjusted in the gear rack fluid-link steering machine gap of good reliability.
To achieve these goals, the technical solution adopted in the utility model is:
Locking mechanism is adjusted in this gear rack fluid-link steering machine gap, comprises the adjustment briquetting in housing and adjusting described gear rack gap; Described housing is stretched in one end of described adjustment briquetting, and the other end end face of described adjustment briquetting is provided with the connecting groove that joint gap is adjusted spanner; Described adjustment briquetting is provided with end, one end and the riveted joint of described housing of connecting groove.
Described adjustment briquetting is provided with end, one end end face and the riveted joint of described housing of connecting groove.
On described adjustment briquetting and described housing, be uniformly distributed the riveting point that is useful on riveted joint.
The riveting point being located on described adjustment briquetting and described housing is three.
The utility model has the advantage of: locking mechanism is adjusted in this gear rack fluid-link steering machine gap, adjust after briquetting is adjusted gap and be directly riveted on housing; First this method has reduced the use of the parts such as locking nut and torque take-up spanner, has reduced cost of production; Secondly, required installing space is little, and that has improved assembly can matching; Finally, the mode difficult drop-off of riveted joint is loosening, has avoided the failure mode that gets loose because of locking nut, has improved the reliability of steering box assembly.
Accompanying drawing explanation
The content of below each width accompanying drawing of the utility model specification being expressed and the mark in figure are briefly described:
Fig. 1 is the structural representation that locking mechanism is adjusted in the utility model gear rack fluid-link steering machine gap;
Fig. 2 is the structural representation that locking mechanism is adjusted in prior art middle gear tooth bar fluid-link steering machine gap;
Mark in above-mentioned figure is:
1, housing, 2, adjust briquetting, 3, riveting point, 4, locking nut.
Embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1, locking mechanism is adjusted in this gear rack fluid-link steering machine gap, comprises the adjustment briquetting 2 in housing 1 and adjusting gear tooth bar gap; Adjust one end of briquetting 2 and stretch into housing 1, the other end end face of adjusting briquetting 2 is provided with the connecting groove that joint gap is adjusted spanner; Adjust end, one end and housing 1 riveted joint that briquetting 2 is provided with connecting groove.
Adjust end, one end end face and housing 1 riveted joint that briquetting 2 is provided with connecting groove, the mode of end face and housing 1 riveted joint, further guarantees that assembling takes up space little.
Adjust on briquetting 2 and housing 1 and be uniformly distributed the riveting point 3 that is useful on riveted joint.The visual concrete condition adjustment of number of riveting point 3, can be three, four, five and six etc. a plurality of.Consider cost and function, being preferably located at the riveting point 3 of adjusting on briquetting 2 and housing 1 is three.
Locking mechanism is adjusted in this gear rack fluid-link steering machine gap, first adjustment briquetting 2 and housing 1 are linked together, with gap adjustment spanner, rotate and adjust briquetting 2, adjust briquetting 2 to the interior movement of housing 1 to adjust the gap of gear and tooth bar, then by the frock that presses in housing 1 and the even riveting riveting point, end contact place 3 of adjusting briquetting 2 and housing 1.
Locking mechanism is adjusted in this gear rack fluid-link steering machine gap, has reduced the parts such as locking nut and torque take-up spanner, has reduced cost; Required installing space is little, and having improved assembly can matching; Avoid the failure mode getting loose because of locking nut simultaneously, improved the reliability of assembly.
Test data shows, uses above-mentioned new gap to adjust the steering box of locking mechanism, and the incidence rate of the return of goods is far smaller than the steering box that locking mechanism is adjusted in existing gap; Finally, after passing through the fatigue test of steering box, all technical of steering box all meets the requirements, and adopts the steering box of the new connecting mode of the present invention to complete the examination of client road simultaneously; And entrucking in batches.
The utility model specific implementation is not subject to the restrictions described above, as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out, all within protection domain of the present utility model.
