Steering system arrangement structure of coach passenger car

Abstract

The invention discloses a steering system arrangement structure of a coach passenger car. The structure comprises a main steering wheel, an auxiliary steering wheel, a main steering column, an auxiliary steering column, a steering gear, a steering rocker arm, a steering track rod, a two-axis angle actuator, and a three-axis angle actuator. The output shaft of the main steering column under the main steering wheel is connected with the input shaft of the three-axis angle actuator. The output shaft of the auxiliary steering column under the auxiliary steering wheel is connected with the input shaft of the two-axis angle actuator. The output shaft of the two-axis angle actuator is connected with the second output shaft of the three-axis angle actuator through a first intermediate transmission shaft. The first output shaft of the three-axis angle actuator is connected with the input shaft of the steering gear through a second intermediate transmission shaft, so as to control swing of the steering rocker arm, thereby realizing steering of wheels through the steering track rod and a steering knuckle arm on a front shaft. The structure is advantaged by compact structure, high reliability, constant speed drive, stable drive, low gear drive noise, and prevents disadvantages of a chain transmission device, and satisfies requirement on a coach passenger car market.

Description

technical field [0001] The invention relates to the field of passenger cars, in particular to an arrangement structure of a steering system of a coach coach. Background technique [0002] The coach car is a special vehicle for driving school training. It is mainly used for the training of driving students. Different from ordinary special-purpose cars, the coach car has special requirements. The technical condition of the coach car should meet the requirements of GB7258 and the second-class car stipulated in JT / T433. above technical conditions. The dual-steering coach coach bus equipped with auxiliary steering system will have more complete functions, better safety and more humanization. [0003] At present, the linkage between the coach owner and the auxiliary steering wheel on the market mainly relies on chain transmission: a gear with the same model and the same number of teeth is installed on the steering gear of the main and auxiliary steering wheels, and the two gears ...

AI Technical Summary

Problems solved by technology

Although this transmission device has a simple structure, there are many shortcomings and even potential safety hazards: the chain transmission gap is large, and the synchronization is too poor; the chain is easy to fall off, and the reliability is too poor; The flexibility is relatively poor; the steering return performance of the chain drive is very poor, or even does not return to the alignment, which poses a great safety hazard
