Hour hands rotation band type brake apparatus unclamps, and steering wheel can turn right direction.When left and right, sensor there is no signal, two sets
Band type brake apparatus is in releasing orientation.The coupling mechanism force of two covering devices can derive from motor or hydraulic system, can be with setting speed
Threshold value, this method is just actuated for when vehicle reaches certain speed.
Brief description of the drawings
System work general principle figure when Fig. 1 is straight-line travelling；
System Working Principle figure when Fig. 2 blows out for right side wheels.
Embodiment
Fig. 1 is system work general principle figure when normal straight travels, and the wherein system includes steering wheel 1 and steering wheel 1
Connected steering column 2, first sensor 3, sensor block 4, second sensor 5, shaft coupling 6, steering spindle 7, the first band-type brake 8, first
One-way clutch 9, the first fixed support 10, the second band-type brake 11, the second one-way clutch 12, laterally the second fixed support 13, drawing
Bar 14, off-front wheel 15, the near front wheel 16 and trailing wheel 17, set when speed reaches 70 kilometers/hour, be actuated for this method.
Now steering wheel 1 remains stationary as, in straight travel state.Pass through shaft coupling 6 between steering column 2 and steering spindle 7
Connection, and gap is maintained, and gap is more than the spacing between sensor block 4 and first sensor 3, sensor block 4 is fixed on steering
On post 2.Spacing between sensor block 4 and first sensor 3 and second sensor 5 is equal, and now two sensors 3 and 5 are equal
Signal is not obtained, and the first band-type brake 8 and the second band-type brake 11 are in relaxation state.First one-way clutch 9 can turn clockwise, and second
One-way clutch 12 is rotate counterclockwise, gap be present between the inner ring and steering spindle 7 of two one-way clutch 9 and 12.First
It is separately mounted to the second one-way clutch 9 and 12 on the first and second fixed supports 10 and 13, the He of the first and second band-type brake 8
11 are separately fixed on the inner ring of the first and second one-way clutch 9 and 12, can be rotated with inner ring.14 be cross-tie, 15
It is the near front wheel for off-front wheel, 16,17 be trailing wheel.
When turning to the right, sensor block 4 is rotated with steering column 2 and contacted with second sensor 5, obtains second sensor 5
Signal, the first band-type brake 8 is locked on steering spindle 7, and the second band-type brake 11 is in relaxation state, and shaft coupling 6 drives 7 turns of steering spindle
Dynamic, the inner ring of the first one-way clutch 9 rotates with the first band-type brake 8.When turning to the left, sensor block 4 is servo-actuated to be connect with first sensor 3
Touch, first sensor 3 is obtained signal, the second band-type brake 11 is locked on steering spindle 7, and the first band-type brake 8 is in relaxation state, connection
Axle device 6 drives steering spindle 7 to rotate, and the inner ring of the second one-way clutch 12 rotates with the second band-type brake 11.
When vehicle is in straight-going state, gap is remained between sensor block 4 and sensor 3 and 5, now two sensings
Device produces without signal.As shown in Fig. 2 right side wheels 15 are blown out suddenly, automatic turn to the right of wheel 15 makes vehicle produce rapidly
Raw Right deviation trend, now steering spindle 7 turn clockwise therewith so that first sensor 3 and sensor block 4 contact, make first sensor
3 obtain signal, and the second band-type brake 11 is locked on steering spindle 7, and the first band-type brake 8 is in relaxation state, is connected in the second band-type brake 11
The second one-way clutch 12 together can only rotate counterclockwise, therefore the clockwise rotation of steering spindle 7 is prevented, so as to avoid
Right side tire 15 deflects to the right, maintains the direction of traveling.When driver thinks adjustment direction to the right, steering wheel is rotated clockwise
1, drive steering column 2 and sensor block 4 to rotate clockwise, sensor block 4 contacts with second sensor 5, is believed second sensor 5
Number, the first band-type brake 8 is locked on steering spindle 7, and the second band-type brake 11 is in relaxation state, and wheel 15 and 16 obtains oneself of right-hand rotation
By going to the right automatically rapidly, now first sensor 3 contacts rapidly with sensor block 4 obtains signal, and wheel 15 and 16 can only obtain
The freedom that must be turned left.When driver is sick for left adjustment direction, because sensor 3 and sensor block 4 are in contact condition, because
This wheel 15 and 16 possesses the freedom to turn left.
Principles above can be applied equally to the situation that left side wheel is blown out.
When vehicle, which is in, turns right state, sensor block 4 and second sensor 5 are in contact condition, now right side front vehicle wheel
15 blow out suddenly, deflect to the right automatically and drive steering spindle 7 smoothly pin rotates, and sensor block 4 and second sensor 5 separate, with the
One sensor 3 is contacted, and the free degree now to turn right is controlled, and wheel 15 can not continue deflection of turning right.If before left side
Wheel 16 is blown out, and now because sensor block 4 and second sensor 5 contact, wheel is not turned left the free degree of deflection, and is turned right
During deflection, sensor block 4 and second sensor 5 separate, the 11 rapid locking of the second band-type brake, and the first band-type brake 8, which is in, loosens shape body, so as to
Wheel 16 can not continue to the right to deflect.
From above-mentioned principle, when no matter wheel left or right front tyre is blown out, wheel can only be passive under steering wheel control
Rotate, and can not thus prevent occurring the situation for robbing steering wheel during front-wheel tyre-burst from main deflection, substantially reduce and blow out what is brought
Rollover risk.
