Abstract
The utility model relates to an electric controlled steering device which includes a steering wheel, a steering wheel rotating shaft, a steering column, a universal joint, a fully hydraulic steering gear and an electric controller; the device is characterized in that a pair of joggled transmission gears and a sensor are added while basically maintaining the structure of an original fully hydraulic steering device, and the sensor inputs a steering signal to the electric controller. The device reduces noise and energy consumption of the hydraulic steering mechanism and improves service life of a motor and a battery.
Description
Technical field
The utility model relates to a kind of vehicle power steering device.
Background technology
At present, steering hardware on the heavy formula batter fork lift truck of domestic equilibrium generally adopts hydraulic power steering, its steering pump DC machine only uses a contactless switch to control as switch, because this mode is fairly simple, after key switch at vehicle is opened, the adhesive of steering hardware contactless switch is switched on, in order to keep system pressure that fluid power turns to, to guarantee the response to bearing circle, its steering pump motor is full speed running all the time; When reaching the left and right sides limit that turns to, the by pass valve of hydraulic efficiency pressure system is opened overflow, if this moment, by pass valve broke down, causes very easily that pump motor is overheated because of the reason of load, overcurrent damages; Therefore such fluid power steering swivel system exists that noise is big, energy consumption is high, influences the defective in motor and storage battery service life.
Summary of the invention
In order to overcome the deficiency that above-mentioned steering hardware exists, the utility model is not changing on the basis of former hydro-steering apparatus structure substantially, and a kind of electric power steering device that can guarantee can effectively reduce again the timely response of bearing circle steering swivel system noise and energy consumption is provided.
Concrete technical solution is as follows:
The electric power steering device, comprise bearing circle 5, bearing circle rotating shaft 1, Steering gear 6, universal-joint 7 and all-hydraulic steering gear 8, it is characterized in that: the bottom of bearing circle rotating shaft 1 is equipped with a driving gear 9, with driving gear 9 ingear driven gears 4 by axle mounting on deflector bearing 2, driven gear 4 tops are installed with rotation direction sensor 3, and rotation direction sensor 3 is connected with electrical control mechanism by lead.
The utility model is not changing on the basis of former hydro-steering apparatus structure substantially, has increased the control mechanism that can implement effectively to control in real time to pump motor newly.The increase of this mechanism makes the steering pump DC machine become the initial velocity operation of setting according to the pump electrical control mechanism by original full speed running all the time, and the incoming signal of accepting steering wheel sensor carries out in real time effectively control, can adjust the response slope of electrical control mechanism, so can guarantee effectively to reduce again the noise and the energy consumption of steering swivel system to the timely response of bearing circle.When reaching the left and right sides limit that turns to, the not overflow even the by pass valve of hydraulic efficiency pressure system breaks down, pump motor can not damage yet, and this device has reduced the noise and the energy consumption of hydraulic steering mechanism, the service life of having improved motor and storage battery.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is Fig. 1 steering shaft structure enlarged diagram.
The specific embodiment
As seen from Figure 1, this automatically controlled hydraulic steering mechanism comprises bearing circle 5, bearing circle rotating shaft 1, Steering gear 6, universal-joint 7, all-hydraulic steering gear 8 and electrical control mechanism.Bearing circle rotating shaft 1 bottom is equipped with a driving gear 9, with driving gear 9 ingear driven gears 4 by axle mounting on deflector bearing 2, driven gear 4 tops are installed with sensor 3, sensor 3 is connected with electrical control mechanism by lead.
Its principle of work is, Vehicle Power is connected, and bend the throttle, turns to the contactless switch adhesive and keeps turning to automatically controlled energising, and the steering pump motor is according to automatically controlled predefined rate of onset running, if this moment, bearing circle was motionless, then hydraulic oil is by the direct oil sump tank of all-hydraulic steering gear; If bearing circle rotates; by transmission gear 9; 4 transmission; sensor 3 on the driven gear 4 sends and turns to impulse singla to give electrical control mechanism; electrical control mechanism carries out speed governing according to the response slope of setting to pump motor; pressure and flow that reaching steering hydraulic system rapidly needs are finished handling maneuver; after reaching the left and right sides limit that turns to; the steering pump motor still keeps running; make the vehicle pivot stud; the steering hydraulic system by pass valve is opened overflow simultaneously; this moment, the maximum operating currenbt (discharge current of storage battery) of pump motor was limited, and motor and storage battery all can be protected.
When bearing circle stops operating, transmission gear 9,4 not transmissions, sensor 3 no turn sign pulses input electrical control mechanisms, electrical control mechanism is got back to the initial setting rotating speed with the control pump motor; After waiting for through time-delay, still completely without input, think then that the driver is in to treat worker's state or left that turn to the contactless switch automatic cutout this moment, stop steering swivel system work, wait control signal is imported the back once more and started as acceleration pedal and bearing circle.
