Explosion-Proof Electric Recirculating Ball Type Electric Power Steering Gear For Mine

Product Description

The recirculating ball electric steering gear assembly produced by the company is a type of automotive electric power steering (EPS). The recirculating ball electric power steering assembly (S-EPS) is suitable for pickup trucks, light trucks, and 9-21-seater box-type vehicles (vans). The system consists of a recirculating ball electric steering gear composed of a torque sensor, a power-assisted motor, a deceleration device, and a recirculating ball mechanical steering gear, together with a controller (ECU) and a steering drive shaft. This is the most novel structure of an electric power steering gear. This kind of S-EPS can all be installed on the frame, and the steering system is safer and easier to deploy. It is easy to replace the original hydraulic device mechanism. It is easier to modify various light trucks. The product is low in cost, easy to install, and has many advantages. It can change the position of the motor and the installation structure of the steering gear according to different vehicle installation requirements, and has great flexibility.

    This kind of recirculating ball electric steering gear (S-EPS) at different vehicle speeds and different angles, according to the torque signal collected by the sensor and the vehicle speed signal provided by the dashboard, so that the controller ECU can provide the appropriate control current according to a certain rule. So that the motor provides different boost and damping, so that the car can achieve the maximum boost and damping effect during the steering process. It is easier to develop high-power motors and matching controller ECU.

The car adopts EPS technology to solve the problem of drifting when the car is running at high speed. It can also increase the angle signal of the sensor according to the needs of different models. Under the control of the controller, the vehicle's active correction function is realized, which solves the problem of the car's return to the timing. Head swing problem. The steering stability of the car is improved, and the steering portability and the steering safety performance of the car are also improved.

Advantage

The advantages of recirculating ball electric power steering S-EPS applied to pure electric commercial vehicles

Compared with traditional hydraulic power steering, recirculating ball electric power steering has the following obvious advantages:

    1. Reduce procurement costs

    Traditional hydraulic power steering is used in pure electric vehicles. Because there is no engine to drive the hydraulic pump, an electric motor and controller are required. The cost is about 1,000 yuan (=$155.00) more than electric power steering.

    2. Reduce the number of parts and realize the lightweight of the whole vehicle

    Hydraulic steering is applied to pure electric vehicles. It needs to be equipped with oil pipes, oil cans, oil pumps, electric motors, controllers and many other components to realize the power steering function; while the electric power steering realizes the integration of the whole machine, which saves time and effort in assembly, and is heavier than hydraulic steering. Reduce by about 50%.

    3. Extend the cruising range by 25%

    Hydraulic steering is applied to pure electric vehicles, and requires at least 2 kilowatts or more of motor to drive, and the motor must not stop working to achieve steering assistance; while electric steering only needs 12V (or 24V) power to work, and it only needs about 400W for supporting minibuses. The motor does not work without turning, and there is very little power loss. After testing, the cruising range can be extended by more than 25%.

Recirculating ball electric steering is suitable for various passenger cars and commercial vehicles. At present, our company's products have covered all models (including passenger cars) with a front axle load of less than 3.6 tons, are national patent products, and have won the China Automobile Industry Association Science and Technology Progress Award.
