Abstract
The utility model provides a kind of automatically controlled steering system for vehicle, directly issues steering order using motor, and then realize wheel deflection by transmission mechanism, has overall structure simple, transmission chain is short, transmission efficiency and advantage with high accuracy.The automatically controlled steering system includes: steering motor, speed reducer, Coupling Shaft, diverter and cross-tie；The steering motor is connected by speed reducer with the Coupling Shaft, and the Coupling Shaft is connected with diverter, and the diverter is used to convert rotary motion to lateral linear motion, the transverse direction for the axial parallel direction of steered wheel；One end of the cross-tie is connected with the diverter output end, and the other end is connected with steered wheel.
Description
Technical field
The utility model relates to a kind of steering systems, and in particular to a kind of automatically controlled steering system belongs to Car design technology
Field.
Background technique
The development of vehicle at present is just welcoming the upsurge of a new round, including unmanned logistic car, unmanned ferry bus, nobody bar
The vehicles such as scholar, unmanned freight.Different from conventional truck, vehicle does not need the steering system operated for people
System, gas pedal and pedal processed.Therefore, the steering system, drive system and braking system of vehicle must independently carry out just
To research and development.
Utility model content
In view of this, the present invention provides a kind of automatically controlled steering systems for vehicle, are directly issued and are turned using motor
Wheel deflection is realized to instruction, and then by transmission mechanism, has overall structure simple, transmission chain is short, transmission efficiency and essence
Spend high advantage.
The automatically controlled steering system for vehicle includes: steering motor, speed reducer, Coupling Shaft, diverter and transverse direction
Pull rod；
The steering motor is connected by speed reducer with the Coupling Shaft, and the Coupling Shaft is connected with diverter, and described turn
To device for converting rotary motion to lateral linear motion, the transverse direction is and the axial parallel direction of steered wheel；
One end of the cross-tie is connected with the diverter output end, and the other end is connected with steered wheel.
Diverter tool is there are two output end, two output one cross-tie of each connection, two cross-ties
The other end is connected with two steered wheels respectively.
The diverter is gear and rack teeth mechanism, and the gear of the Coupling Shaft and gear and rack teeth mechanism is coaxially affixed, described
Cross-tie is connected with the rack gear.
The utility model has the advantages that
The system directly issues steering order using motor, real using pinion and-rack reverse drive gear and cross-tie
Existing wheel deflection, has overall structure simple, transmission chain is short, transmission efficiency and advantage with high accuracy.
Detailed description of the invention
Fig. 1 is the main view of the utility model；
Fig. 2 is the explosive view of the utility model；
Fig. 3 is the utility model side view；
Fig. 4 is the utility model side cut-away view.
Wherein: 1- steering motor, 2- speed reducer, 3- Coupling Shaft are supported on 4- diverter, are supported under 5- diverter, and 6- is horizontal
To pull rod, 7- diverter.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
Motor-driven steering system is utilized for unmanned vehicle the present embodiment provides a kind of.As shown in Figs 1-4, the steering
System includes: steering motor 1, speed reducer 2, Coupling Shaft 3, diverter 7 and two cross-ties 6.Wherein steering motor 1 is servo
The output shaft of motor, steering motor 1 is threadedly coupled by the bolt hole on itself with the input shaft of speed reducer 2, speed reducer 2
Output shaft is connect with one end of Coupling Shaft 3 by flat key, and the other end of Coupling Shaft 3 is connect with diverter 7 by spline, diverter
7 are fixed on vehicle frame by support 5 under support 4 on diverter and diverter.
Diverter 7 is gear and rack teeth mechanism, and wherein Coupling Shaft 3 and the gear of gear and rack teeth mechanism are coaxially connected by spline
It connects, the both ends of the rack gear of gear and rack teeth mechanism respectively connect a cross-tie 6, and thus Coupling Shaft 3 drives gear teeth in rotation
Item movement, pushes cross-tie 6 to move along a straight line.Wherein the axial direction of cross-tie 6 is axial parallel with steered wheel, and two
The other end of cross-tie 6 is separately connected two steered wheels, and thus steering system is diverted through motor 1 to control.
The power transmission path of the steering system are as follows: torque is input to Coupling Shaft 3 by retarder 2 by steering motor 1, with
Torque is transmitted to diverter 7 by Coupling Shaft 3 afterwards, and 7 internal gear rack gear of diverter converts cross force for input shaft input torque and passes
Track rod 6 is handed to control deflecting roller and swing steering.
In conclusion the above is only the preferred embodiments of the present utility model only, it is not intended to limit the utility model
Protection scope.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all wrap
Containing being within the protection scope of the utility model.
