Abstract

Disclosed is a rack-pinion type steering apparatus. According to the present invention, since air can flow into the interior of a gearbox from the exterior of the gearbox, unlike in the conventional structure in which an internal air flow into the gearbox is blocked at a portion of a rack-pinion type steering apparatus connected with the gearbox through a rack housing and a bellows, a problem of increasing internal pressure of the bellows in a predetermined case can be solved, and accordingly, generation of noise due to the collision between an inner peripheral surface of the bellows and an inner ball joint can be prevented.

Description

technical field [0001] The present invention relates to a rack and pinion steering device, more particularly, to a rack and pinion steering device that allows the inside of a gearbox to communicate with the outside air to solve the problem of increased internal pressure of a bellows under a predetermined condition problems, thereby preventing the generation of noise due to the collision of the inner peripheral surface of the bellows with an inner ball joint. Background technique [0002] figure 1 It is a schematic diagram of a rack and pinion steering device in the prior art. figure 2 yes figure 1 Sectional view of the main parts of the Zhongyi gearbox. [0003] As shown in the figure, the rack and pinion steering device according to the related art includes: a steering wheel 100, which is arranged on the driver's seat; a steering shaft 105, which is connected to the steering wheel 100, and a driving rod 103 , used to fix the steering shaft 105 on the vehicle body; a ge...
