Problems solved by technology

However, it has the following disadvantages: 1. The output shaft of the three-way steering commutator and the input shaft of the steering gear must be coaxially assembled, and the accuracy of the installation and fixing position is high, and the adjustment is difficult
When the output shaft of the commutator and the input shaft of the steering gear are working, they should rotate coaxially, otherwise it is easy to get stuck, and the steering loss of control will cause a major accident; 2. The connection between the steering gear and the three-way steering commutator is by the coupling 3. After the steering gear is docked with the three-way steering commutator, the input shaft of the three-way steering commutator will exceed the floor of the cab, which is not convenient for the layout of the steering transmission device, and there are problems in the layout space. Big problem; 4. The three-way commutator is far away from the frame, and it is not easy to design a bracket to fix it; 5. There are many transitional connection parts between the steering gear and the two sets of steering transmission devices, and the cost is high

Abstract

A steering gear assembly for an instructional car comprises a steering gear shell. The steering gear shell is provided with a steering gear output shaft and a steering gear main input shaft which areperpendicular; the steering gear main input shaft is connected with a steering machine torsion rod through a spline sleeve; a steering gear auxiliary input shaft is further arranged on the steering gear shell; and the steering gear auxiliary input shaft and the steering gear main input shaft are mutually perpendicular and are connected through a conical gear. The steering gear assembly is simple in structure, safe, reliable and low in cost, and dangerous situations during driving learning can be effectively avoided.

Description

technical field [0001] The invention relates to a steering gear assembly, in particular to a steering gear assembly for a coach vehicle. Background technique [0002] The coach car is a vehicle specially used for teaching in driving schools. Mainly used for driver training. Different from ordinary special-purpose vehicles, the coach car has its own special requirements. The technical condition of the coach car should meet the requirements of GB 7258 and the technical conditions of second-class vehicles stipulated in JT / T 198, and it is equipped with auxiliary rearview mirrors, auxiliary Brake pedal, fire extinguisher and other safety protection devices. The road driving coach car also needs to be equipped with an auxiliary accelerator pedal and an auxiliary clutch pedal. [0003] Nowadays, more and more coach trucks and coach buses start to adopt double-steering wheel steering system, which is commonly known as a double-steering wheel coach. That is, a steering wheel is ...
