Description

The electric steering drive for hybrid cars Technical field The invention relates to the technical field of automobile steering structure, in particular to an electric steering drive device for a hybrid electric car. s Technical background At present, the center of gravity of the front wheel of the electric tricycle is too high, the steering resistance 1s large, the rigidity of the axle load is small, which affects the running stability, and there are safety hidden dangers to a large extent. In addition, most of the driving motors used in electric tricycles and electric cars are driven by single motors. Motor is the greatest power preparation according to the electric power, and in the process of electric vehicle real driving, electric vehicle is the need of special power and general power, single motor configuration is very difficult to reach these two requirements at the same time, there is a difference of electric vehicle dynamic performance and the problem of low efficiency, especially in the electric start, acceleration and climbing process problem is obvious, and poor battery life.

In hybrid car power steering technology, tend to adopt more driving steering structure, the first structure to use is not very effective, especially in the field of electric vehicles, this structure is often caused by weight is bigger, cannot meet the requirement of the weight of the electric car as light as possible, so a quality light, stable operation of electric steering structure has great market prospect.

Content of invention The purpose of the invention is to provide an electric steering drive device for a hybrid electric car to solve the problems mentioned in the background technology.

To achieve the above purposes, the mvention provides the following technical solutions: Vehicle chassis and wheels installed column, rotating bearing, steering gear, worm drive, transmission gear, shaft, gear, motor, steering wheel shaft and controller, described in the bodywork chassis for the automobile chassis front end, described rotary bearing installed on both sides of the vehicle chassis, described the wheels installed column end fixed on the bearing, described in the steering gear as the semicircle helical gear, steering gear fixed on the wheel installed column, referred to drive the worm through the bearing seat is installed on the car body, described the power shaft through the gear respectively connected with two drive worm, described the power gear fixed on the power shaft, The power motor output shaft 1s connected to the power gear through a gear, the controller 1s an information converter, the controller is connected to the power motor through a signal line, and the steering wheel shaft is connected to the controller.

Furthermore, the controller is composed of an information converter and a control circuit.

Further, the information converter is a conversion device for converting mechanical signals into electronic signals.

Further, the control circuit 1s a control device for the direction and magnitude of the current.

Further, the steering wheel shaft is made of aluminum alloy material.

Compared with the existing technology, the imvention has the following beneficial effects:

1. Simple organization and low cost;

2. Lightweight in quality to meet the use demand of electric vehicles; s 3. Stable operation and strong safety performance. The invention has the advantages of simple structure, light weight and stable operation. The appended drawings show FIG. 1 is the overall structure diagram of the invention; Figure 1- Chassis; 2- Wheel mounting column; 3- Rotary bearing; 4- Steering gear; 5- Driving worm; 6- Transmission gear; 7- Power shaft; 8- Power gear; 9- Power motor; 10- Steering wheel shaft; 11- Controller.

Specific implementation method The following is a clear and complete description of the technical scheme in the embodiments of the invention in combination with the appended drawings in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, but not all of them. Based on the embodiments in the vention, all other embodiments obtained by ordinary technicians in the field without making creative work fall within the scope of protection of the invention.
