| 摘要 | PURPOSE:To enable an adoption of steering gear ratio to a preferable portion in a wide range, and remarkably improve a straight drive stability and steering effort, by providing a variable rack tooth directly in the rack bar. CONSTITUTION:The rack.pinion steering gear is provided with a rack bar 1, and this rack bar 1 is supported within the housing rotatably and shiftably in the direction of axial line, and to the housing is rotatably supported a pinion 3 meshed to a rack tooth 2 on the bar 1. The rack tooth 2 is provided by directly gear cutting the bar 1, and for this tooth 2 on the X-axis corresponding to the axial line of the bar 1, O shows the meshing part when in a straight drive, and those in its right and left show the standard rack pitch points 1-14. A variable pitch line a is for changing an axially shifting amount of the bar 1 for rotation o the pinion 3. In this way, a steering gear ratio can be adopted to a preferable portion in a wide range. | ||||||
