Description
Technical field
The utility model relates to automobile component, particularly a kind of automobile electric power-assisted steering machine tooth bar.
Background technology
Automobile electric power-assisted steering machine tooth bar, comprise the teeth portion of left end and the bar portion of right-hand member, operationally, tooth bar is in enclosure interior sway for automobile steering device, body of rod surface (being called functional areas in the industry) and the shell inner surface of the teeth portion back side and bar portion right-hand member 180mm scope have friction, if friction force is too large, can produce noise when turning to, operation is required great effort very much, traveling comfort is poor, displacing force is large, easily produces friction heat, causes the defects such as part life reduction.
Utility model content
The purpose of this utility model, exactly in order to solve the problem, provides a kind of automobile electric power-assisted steering machine tooth bar of new structure.
The purpose of this utility model is achieved in that a kind of automobile electric power-assisted steering machine tooth bar, comprises the teeth portion of left end and the bar portion of right-hand member, and the back side of described teeth portion adopts longitudinal polishing lines, and one section of described bar portion adopts longitudinal polishing lines.
Longitudinal polishing lines at the described teeth portion back side covers 170 degree of arc surfaces at the teeth portion back side.
Longitudinal polishing lines in described bar portion covers 360 degree of peripheries of one section of body of rod of the end length 180mm that keeps right.
Adopt automobile electric power-assisted steering machine tooth bar of the present utility model, reduce displacing force, reduce noise, improve displacing force inspection once by qualification rate, add the service life of tooth bar and housing, improve the level of comfort that user turns to.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the basic structure schematic diagram of the utility model automobile electric power-assisted steering machine tooth bar;
Fig. 3 is the radial sectional structure schematic diagram of the teeth portion in the utility model;
Fig. 4 is the radial sectional structure schematic diagram in the bar portion in the utility model.
Detailed description of the invention
See Fig. 1, coordinate see Fig. 2, Fig. 3, Fig. 4, automobile electric power-assisted steering machine tooth bar of the present utility model, comprises the teeth portion 1 of left end and the bar portion 2 of right-hand member, the back side 11 of teeth portion adopts longitudinal polishing lines, and this longitudinal polishing lines covers 170 degree of arc surfaces at the teeth portion back side.One section 21 of bar portion adopts longitudinal polishing lines, and this longitudinal polishing lines covers 360 degree of peripheries of one section of body of rod of the end length 180mm that keeps right.
Automobile electric power-assisted steering machine tooth bar of the present utility model due at it for have employed longitudinal polishing lines with the functional part of body contact, reduce displacing force, reduce noise, add the service life of tooth bar and housing, improve the level of comfort that user turns to.
