Description
Technical field
The utility model relates to automobile steering device field, particularly relates to a kind of rack and pinion steering gear.
Background technology
Along with the fast development of economy, automobile has become the indispensable vehicle in people's life.Automobile steering device is the important component part of automobile, its radical function be change automobile travel direction and automotive is kept steady fixed straight-line travelling.Deflector is the power element of steering system hydraulic power-assisted, and the rotation of steering handwheel is mainly become the straight-line motion of rack shaft or the swing of pitman arm by it, reduces kinematic velocity, increases steering torque and changes the rotation direction of steering torque.
Chinese patent CN202213617U discloses a kind of existing automobile steering device, as Fig. 1, comprise input shaft, be connected to the dust seal on input shaft and adjust plug screw, be positioned at the bearing bottom adjustment plug screw and be positioned at the steering gear housing of deflector, the position of its dust seal is positioned at the top of adjustment plug screw, on dust seal, be provided with dust boot, steering housing external surface is provided with longitudinal drainage groove.Its mainly by the position of dust seal from adjustment plug screw bottom adjust to its top, improve the height of dust seal, make moisture not energy product input shaft and adjustment plug screw gap in, dust seal adds dust boot.But the dust boot in this technology just merely protect steering gear housing moisture and the entering of dust, and do not arrange O RunddichtringO, sealing property is lower.
Utility model content
For the problems referred to above, the purpose of this utility model overcomes above-mentioned poor sealing performance, the problem of easy oil spill and anti-dust performance difference, provides one and can effectively prevent dust and other impurity from entering in housing, the automobile steering device that housing inner fluid overflows.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of rack and pinion steering gear, it is characterized in that: this deflector comprises diverter body, steering gear housing, miniature gears, tooth bar, miniature gears lining, tooth bar supporting, a part for described tooth bar possesses the rack tooth of inclination, can be configured in steering gear housing according to the mode of direction of principal axis displacement; Described miniature gears possesses miniature gears intermeshing with described rack tooth, and when axle drives miniature gears to rotate, tooth bar does straight-line motion; Described miniature gears lining can be configured in steering gear housing in rotary manner, and miniature gears outside is provided with dust boot, and described dust boot and steering gear housing are fastenedly connected; Described tooth bar supporting is tubular, and can support described tooth bar slidably from the direction of width in inner side, described diverter body is provided with the combination sealing of oil sealing and O RunddichtringO.
Further, described tooth bar is supported by tooth bar and adjusts plug screw and fixes, and between tooth bar supporting and adjustment plug screw, spring is housed, adjustment plug screw here not only can play fixed pedestal effect, can also use as the center shaft of spring simultaneously.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
1, the dust and water protection performance of deflector is improved by arranging dust boot.
2, combine make sealing property better by arranging oil sealing and O RunddichtringO.
3, this rack and pinion steering gear structure is simple, and safety performance is strong, long service life.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is a kind of automobile steering device structural representation of prior art.
Fig. 2 is a kind of rack and pinion steering gear structural representation of the utility model.
In figure, each label represents successively: 1-tooth bar, 2-dust boot, 3-oil sealing, 4-O RunddichtringO, 5-steering gear housing assembly, 6-miniature gears lining, and 7-tooth bar supports, 8-spring, 9-adjustment plug screw.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 2, a kind of rack and pinion steering gear of the present utility model comprises: diverter body, steering gear housing 5, miniature gears (not shown), tooth bar 1, miniature gears lining 6, tooth bar supporting 7, described steering gear housing 5 is coated on outside diverter body, a part for described tooth bar 1 possesses the rack tooth of inclination, can be configured in steering gear housing according to the mode of direction of principal axis displacement; Described miniature gears (not shown) possesses pinion gear teeth intermeshing with described rack tooth; Described miniature gears lining 6 can be configured in steering gear housing in rotary manner; Described tooth bar supporting 7 is tubular, can support described tooth bar slidably in inner side from the direction of width.When in diverter body, axle drives miniature gears (not shown) to rotate, tooth bar 1 does straight-line motion, thus drives deflector normally to run.Described tooth bar 1 is fixed by tooth bar supporting 7 and adjustment plug screw 9, between tooth bar supporting 7 and adjustment plug screw 9, spring 8 is housed, adjustment plug screw 9 here not only can play fixed pedestal effect, can also use as the center shaft of spring 8 simultaneously, by adjusting the effect of plug screw 9 and spring 8, position-limiting action can be played to tooth bar 1, it is made to make cross travel, and rocking of deflection both sides can not be produced, so also reach the object of raising equipment working stability, and also more flexible during operation.Described miniature gears (not shown) outside is provided with dust boot 2, and this dust boot 2 is close to miniature gears (not shown), and another side and steering gear housing 5 are fastenedly connected, and avoids dust, moisture and earth etc. to enter whipstock system.Described diverter body is provided with the combination sealing of oil sealing 3 and O RunddichtringO 4, and effectively prevent housing inner fluid from overflowing, sealingly secure, prevents oil leakage phenomenon.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
