Description
Technical field
A kind of novel steering device for steering-by-wire is the utility model is related to, belongs to the technology neck of passenger car steering gear
Domain.
Background technology
Mechanical steering gear and can be divided into pinion and-rack, circulating ball type, worm according to the difference of structure type
Stylus pin formula, circulation ball crank stylus pin formula, worm screw roller type etc..Common is pinion and-rack, circulating ball type, worm stylus pin
Formula.
Rack and pinion steering gear is a kind of simplest steering gear.Its advantages of is simple in structure, compact, and rigidity is big,
It is of low cost, turn to it is sensitive, forward and inverse rate of attacking is all high, easy to arrange, and particularly suitable for candle type suspension and McPherson suspension
Adapted, can also directly drive drag link, simplify steering gear.Therefore obtained on car and micro-, pickup truck extensively
Using.
The forward and inverse rate of attacking of recirculating ball-type steering is all very high, therefore manipulates light, long lifespan, stable and reliable in work；But due to
Counteroffensive rate is very high, causes easily to pass to road shocks power on steering wheel.
Dynamical type steering gear is exactly that mechanical steering gear is grouped together to be formed with steering augmentor in fact.By biography energy
The difference of medium, power steering stgear have two kinds of vapour-pressure type and fluid pressure type.Hydraulic power steerig device therein turns according to mechanical
To arrangement in transfer of device, power cylinder and steering control valve three and the difference of connecting relation, and can be divided into
Monoblock type（Mechanical steering gear, power cylinder and steering control valve three design are integrated）, semi-monolithic formula（Turn mechanical
Together with the design of device and steering control valve, power cylinder is independent）And separate type（Mechanical steering gear is independent, is controlled turning to
Valve and power cylinder design processed is integrated）Three kinds of structural shapes.
There was only a toothed rack inside existing rack and pinion steering gear, left and right wheels turn to linkage, can not realize left and right car
Wheel individually control.
The content of the invention
The purpose of this utility model is to provide a kind of novel steering device for steering-by-wire, it can realize that left and right wheels turn
To independent control；With two kinds of operating modes, it is convenient to free switching.
What the technical solution of the utility model was realized in：A kind of novel steering device for steering-by-wire, by motor,
Housing, left rack, motor, right rack, electromagnet, resetting spring, lock pin composition, it is characterised in that：Right rack first half
For rod-like structure, latter half is tubular structure, left rack generally rod-like structure, and the latter half of left rack is inserted into right rack
In the pipe of latter half, latch, left rack and right rack insertion housing are provided with the bar of the first half of left rack and right rack
Interior, left motor is arranged in the left side of housing, and right motor is arranged in the right side of housing, and the output shaft of left motor passes through gear
Engaged with the latch on the left rack of enclosure interior, the output shaft of right motor passes through the latch on gear and the right rack of enclosure interior
Engagement, two lock pins are respectively arranged the left and right sides in the housing by electromagnet, there is reset bullet between lock pin and electromagnet
Spring, lock pin are particularly located at the lower section of left rack and right rack in housing.
The good effect of the utility model is that it can realize that left and right wheels turn to individually control；With two kinds of operating modes,
Can easily free switching.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the lock pin local structural graph of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：As shown in Figure 1, 2, it is a kind of for the new of steering-by-wire
Type steering gear, is made of motor 1, housing 2, left rack 3, motor 4, right rack 5, electromagnet 6, resetting spring 7, lock pin 8, its
It is characterized in that：Right 5 first half of rack is rod-like structure, and latter half is tubular structure, left rack 3 generally rod-like structure,
The latter half of left rack 3 is inserted into the pipe of right 5 latter half of rack, is opened on the bar of the first half of left rack 3 and right rack 5
There is latch, left rack 3 and right rack 5 are inserted into housing 2, and left motor 1 is arranged in the left side of housing 2, and right motor 4 is arranged in
The right side of housing 2, the output shaft of left motor 1 are engaged by gear with the latch on the left rack 3 in the inside of housing 2, right motor 4
Output shaft engaged by the latch on the right rack 5 in the inside of gear and housing 2, two lock pins 8 are respectively arranged by electromagnet 6
, there is resetting spring 7 in the left and right sides, lock pin 8 is particularly located at left tooth in housing 2 in housing 2 between lock pin 8 and electromagnet 6
The lower section of bar 3 and right rack 5.
It has two kinds of operating modes, under normal running mode.Electromagnet 6 powers off, pressure of the lock pin 8 in resetting spring 7
In the pin hole of the lower insertion left side rack 3 of power effect, left and right rack locking can not relative motion.Right side at this time（Or left side）Electricity
Machine 6 drives the side-to-side movement at the same time of two toothed racks, realizes normally travel.
Under park mode, electromagnet 6 is powered, and lock pin 8 overcomes the tension force of resetting spring 7 under magneticaction, exits a left side
The pin hole of side rack 3, left and right rack release locking, can be respectively relative to steering gear housing movement.At this time, by both sides motor point
Not Dai Dong both sides rack move out, individually controlled so as to fulfill left and right wheels.
