Abstract
The utility model discloses a kind of supporting construction of automobile steering gear rack, comprise stepped cylinder and the longitudinal slot on it, longitudinal slot uniform in described stepped cylinder is four, the bottom surface of these four uniform longitudinal slots is in the lower end of cylinder, longitudinal slot uniform on cylinder is four, four mutual stagger arrangement of groove in its position and described stepped cylinder, the bottom surface of four longitudinal slots uniform on this cylinder flushes with the ring surface of described stepped cylinder the inner, the outer peripheral face of described cylinder is provided with the groove matched with O RunddichtringO, the inner hole surface of described cylinder is evenly equipped with storage grease pit.The utility model has abnormal sound advantage little and easy to assembly.
Description
Technical field
The utility model relates to a kind of automobile steering device, particularly a kind of supporting construction of automobile steering gear rack.
Background technology
Existing automobile steering gear rack supporting mechanism, one end of tooth bar is by wheel and rack elongate support, the other end is supported by supporting mechanism, by sliding motion between this supporting mechanism and tooth bar, desirable support should have less force of sliding friction and high rigidity, existing supporting construction is the step cover that plastics are made, this step is set in housing bore, one end of tooth bar is loaded in the hole of this step cover, the minor diameter cylinder of step cover is evenly equipped with three axial grooves, the bottom surface of groove is step body bottom, i.e. three non-through step bodies of groove.The abnormal sound that this supporting construction in use produces is larger.
Summary of the invention
The utility model object is to provide the supporting construction of a kind of abnormal sound a kind of automobile steering gear rack little and easy to assembly.
The technical scheme realizing the utility model object is a kind of supporting construction of automobile steering gear rack, comprise stepped cylinder and the longitudinal slot on it, it is characterized in that: longitudinal slot uniform in described stepped cylinder is four, the bottom surface of these four uniform longitudinal slots is in the lower end of cylinder, longitudinal slot uniform on cylinder is four, four mutual stagger arrangement of groove in its position and described stepped cylinder, the bottom surface of four longitudinal slots uniform on this cylinder flushes with the ring surface of described stepped cylinder the inner, the outer peripheral face of described cylinder is provided with the groove matched with O RunddichtringO, the inner hole surface of described cylinder is evenly equipped with storage grease pit.What described cylinder outer peripheral face was arranged is two with the O RunddichtringO groove that matches.
The utility model has abnormal sound advantage little and easy to assembly compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is front view of the present utility model; Fig. 2 is the upward view of Fig. 1; Fig. 3 is the birds-eye view of Fig. 1; Fig. 4 is the B-B cut-away view of Fig. 2.
Detailed description of the invention:
In conjunction with following embodiment, the utility model is elaborated, for the defect that existing supporter exists, following improvement is done to the structure of existing stepped cylinder, conveniently assemble, four uniform longitudinal slots 5 are changed into the longitudinal slot of three on cylinder 1, three longitudinal slots in stepped cylinder 3 change four uniform longitudinal slots 4 into, the mutual stagger arrangement in position of four grooves in described stepped cylinder and four grooves on cylinder, and four circular grooves 2 matched with O RunddichtringO are set on the outer peripheral face of cylinder, described cylinder inner hole surface is evenly equipped with the pit 6 of storage grease, the bottom land of four longitudinal slots uniform in above-mentioned stepped cylinder is located at the bottom of cylinder, the bottom land of four longitudinal slots uniform on described cylinder is equal with stepped cylinder internal spherical surface.
The utility model due to the quantity of the longitudinal slot arranged on cylinder and step post many, thus assemble time more convenient; Owing to setting up elastic seal ring, realize reducing tooth bar kinetic friction force and support stiffness by adjusting the parameters such as the hardness of seal ring, thus the life-span of supporting construction is improved.
