A kind of auxiliary steering device for coach car

Abstract

The invention discloses an instructional car auxiliary steering device, and belongs to the technical field of car steering transmission. The instructional car auxiliary steering device comprises a planetary gear mechanism and two brake mechanisms. A main drive steering wheel and an auxiliary drive steering wheel are respectively meshed with two planet gears of the planetary gear mechanism through bevel gears, and used as input ends of control directions. An output end of the control directions is a planet carrier, and the planet carrier is connected with an input shaft of a steering gear through another bevel gear. When a driver drives a car, the driver only needs to keep the auxiliary drive steering wheel still, uses the main drive steering wheel to fully control driving directions, a coach turns the auxiliary drive steering wheel so as to correct the driving directions in necessity, and the coach brakes the main drive steering wheel in an emergency so as to control the driving directions of the car fully through the auxiliary drive steering wheel. The instructional car auxiliary steering device enables the coach to always conveniently master the driving directions of the car, reduces accident rate, and improves drive training safety.

Description

technical field [0001] The invention relates to a steering device, in particular to an auxiliary steering device applied to a coach car, and belongs to the technical field of automobile steering transmission. Background technique [0002] The coach car is a vehicle used by driving schools to train car drivers. Since beginners are very unfamiliar with vehicles and driving, more and more driving schools are beginning to try to use double-steering wheel coach cars. This type of coach car is characterized by an additional One steering wheel is used by the trainer. The trainer can correct the steering status of the trainees at any time according to the situation. In an emergency, it can avoid serious accidents such as improper steering or collision with other vehicles caused by trainees' misuse. The steering system requires two steering wheels. And the corresponding steering gear is connected to the steering gear at the same time to control the working state of the steering gear,...
