Abstract
The utility model relates to an electric power-assisted device for steering of a motor vehicle, in particular to a steering power-assisted device for mini-sized and light coaches and trucks. The electric power-assisted steering device of a motor vehicle comprises a steering wheel, a steering engine and a steering sleeve, and is characterized in that a steering column is arranged on the lower portion of the steering sleeve, a steering motor and an ECU (electronic control unit) control system are mounted on the steering column, a sensor of the ECU control system is mounted on the upper portion of the steering column, the steering column is fixedly connected with a lower steering shaft assembly by a universal joint, and the ECU control system is connected into an ignition switch. The electric power-assisted steering device of a motor vehicle has the advantages that the electric power-assisted steering device is simple in structure and fine in control effect and effectively solves the problems of heavy steering and easiness for drivers to feel fatigue after driving for a long time since the mini-sized and light coaches and trucks cannot employ hydraulic power-assisted steering due to constraint factors such as space and the like, and can only adopt purely mechanical steering.
Description
Technical field
The utility model relates to a kind of motor vehicle steering device, particularly a kind of electric power-assisted steering apparatus that is suitable for the power actuated vehicle of miniature, light-duty passenger-cargo automobile.
Background technology
Miniature at present, light-duty passenger-cargo automobile can't use hydraulic power-assisted steering because of being subjected to factor restrictions such as space, can only use Purely mechanical to turn to, and the mechanical steering mode is heavier, for the master worker of long-duration driving, it is fatigable to occur driving easily, thereby causes the generation of traffic accident.
Summary of the invention
In order to remedy the deficiencies in the prior art, the utility model provides the electric power-assisted steering apparatus of a kind of convenient installation and labour-saving power actuated vehicle.
The utility model is achieved by the following technical solution:
A kind of electric power-assisted steering apparatus of power actuated vehicle, comprise bearing circle, steering box and turn to sleeve pipe, its special character is: the described sleeve pipe bottom that turns to is provided with steering column, steer motor and ECU control system are installed on the steering column, the sensor of ECU control system is installed in and rotates tubing string top, steering column is captiveed joint by universal-joint with following steering shaft assembly, and the ECU control system inserts ignition lock.
The electric power-assisted steering apparatus of this power actuated vehicle, be by increasing the power steering motor, this power steering motor drives steering column in the ECU control system and rotates, the sensor of ECU control system is installed in and rotates tubing string top, when steering wheel rotation, bearing circle drives and turns to sleeve pipe to rotate, thereby driving torque is passed on the sensor on steering column top, sensor is passed to the ECU control system with signal, thereby realize rotating assist motor and drive the steering column rotation, should captive joint by universal-joint with following steering shaft by the rotation tubing string in the bottom, guarantee no any relative motion between steering column and the following steering shaft with this, guarantee the stability of sensor signal output and the continuation that assist motor turns to, the ECU control system inserts ignition lock, so that just can work with regard to sensor when realizing automobile starting.
Turn to difficulty in order to solve automobile low speed, the high speed steering problem of unstable, described ECU control system is inserted on vehicle speed signal and the engine revolution signal wire (SW), this system is by gathering vehicle speed signal and engine rotational speed signal, process ECU control system synthesis processing controls electrical motor and deceleration increase turns round mechanism, provides corresponding power-assisted to motor turning.
The beneficial effect of the electric power-assisted steering apparatus of the utility model power actuated vehicle: simple in structure, control effective, well solved miniature, light-duty passenger-cargo automobile and can't use hydraulic power-assisted steering because of being subjected to factor restrictions such as space, can only use Purely mechanical to turn to, and the hard steering that causes, the fatigable problem of long-duration driving.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1, bearing circle, 2, turn to sleeve pipe, 3, the power steering motor, 4, the ECU control system, 5, steering column, 6, steering box, 7 ignition locks, 8, vehicle speed signal, 9 engine revolution signals, 10, universal-joint.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises bearing circle 1, steering box 6 and turns to sleeve pipe 2, it is characterized in that: described sleeve pipe 2 bottoms that turn to are provided with steering column 5, power steering motor 3 and ECU control system 4 are installed on the steering column 5, the sensor of ECU control system 4 is installed in and rotates tubing string 5 tops, steering column 5 is captiveed joint by universal-joint 10 with following steering shaft assembly, ECU control system 4 inserts ignition lock 7, and described ECU control system 4 inserts on vehicle speed signal 8 and engine revolution signal 9 lines.
The utility model adopts on its steering box structure basis of invariable of power actuated vehicle, only increase a power steering motor, this power steering motor drives steering column and rotates under 4 controls of ECU control system, the direction that the compound power steering form of this kind has overcome pure mechanical steering mode is heavy, the long-duration driving fatiguability, overcome again because of miniature simultaneously, light-duty passenger-cargo automobile is subjected to the difficult problems that hydraulic power-assisted steering is installed of factor restriction such as space, when steering wheel rotation turns to, ECU control system 4 receives impulse singla by sensor, promptly control motor steering motor 3, power steering motor 3 produces the driving torque of forward, rotate the tubing string rotation thereby drive, thereby realize turning to of automobile, than light many of simple dependence steering box 6.
