Automobile 90-degree deflection angle steering reverser

Abstract

The invention relates to an automobile 90-degree deflection angle steering reverser. The automobile 90-degree deflection angle steering reverser is characterized in that a box body (1) is included, a channel which is turned by 90 degrees is formed in the box body (1), a vertical rotating shaft assembly (2) and a transverse rotating shaft assembly (3) are arranged in the channel, the middle section of the vertical rotating shaft assembly (2) and the middle section of the transverse rotating shaft assembly (3) are respectively provided with a framework oil seal (4), a compressing ring (5), a bearing (6) and a bevel gear (7) from outside to inside, the two bevel gears (7) are meshed with each other, inverted tooth clamping grooves are formed in the middle section of the vertical rotating shaft assembly (2) and the middle section of the transverse rotating shaft assembly (3), and the compressing rings (5) are embedded into the inverted tooth clamping grooves. The automobile 90-degree deflection angle steering reverser has the advantages of being good in stability, low in noise, good in dust tightness and good in universality.

Description

technical field [0001] The invention relates to a steering commutator for a 90° automobile displacement angle, which belongs to the field of automobile manufacturing. Background technique [0002] With the rapid growth of my country's highway passenger transport, tourist passenger transport, and urban bus passenger volume and the introduction of foreign advanced passenger car technology, the model structure of my country's bus market is gradually changing, urging the technological progress of my country's passenger cars to high specific power and high reliability. , high comfort, large-scale, humanized and low-floor urban buses, and good performance-price ratio. [0003] At present, when my country's automobile factories arrange the steering transmission mechanism, the traditional arrangement is that the steering column is directly connected with the input shaft end on the steering machine through the universal joint yoke at the bottom end, and the power is transmitted throug...

AI Technical Summary

Problems solved by technology

[0004] In the traditional 90° automotive steering commutator, the modulus of the gear is 3.6 mm, a gear has 15 teeth, and the contact between the tooth surfaces is small, so there are defects of poor meshing stability and high noise; the bearing is 9mm thick, the bearing is thin, and the radial stability of the rotating shaft is poor; there are two inner lip surfaces of the skeleton oil seal, and the dustproof effect is poor; the shaft circlip is installed on the rotating shaft, and the shaft circlip has axial movement after long-term use 1. The axial stability of the rotating shaft is poor; the inner end of the rotating shaft is connected to the box through a needle bearing, and the universality of the connection is poor
