Abstract
A vehicle with the steering front and back wheels is disclosed, and features that its radius for turning round can be reduced by about 1/2. Its advantages is flexible drive.
Description
The invention belongs to the vehicle drive applications technical field.
At present in the vehicle drive applications technology only with front-wheel or the unidirectional turning of trailing wheel, its turn radius big (with the present invention relatively), very flexible, vehicle turning driving difficulty (comparing) just under the situation narrow at road, that vehicle is many, the place is less with the present invention.Be necessary further to improve the technology that turns to of vehicle.The technology that all turns to vehicle front and rear wheel of the present invention can improve the alerting ability of vehicular drive, property freely.
Characteristics of the present invention:
Be on the front and rear wheel position of vehicle, steering hardware to be housed all.The direction of passage dish can be handled turning to of front and rear wheel simultaneously, than present similar car (cart and cart, dolly and dolly, rolling cart and rolling cart etc.) turn radius can shorten nearly 1/2 distance (referring to the comparison of Fig. 1 and Fig. 2), it drives more flexible, more freely.As Fig. 1: be front and rear wheel vehicle with steerable turn radius scheme drawing of the present invention; As Fig. 2: be present vehicle one-way wheel (front-wheel or trailing wheel) turn radius scheme drawing.
Key problem in technology of the present invention:
One, 4. (gear adapter shaft) be housed onboard 5. (rack shaft) in the front and rear wheel steering hardware of the vehicle part coupled together, the control of direction of passage dish 4. the hand of rotation of (gear adapter shaft) go control 5. the sense of motion of (rack shaft) control the turning to of wheel (can referring to Fig. 3, Fig. 4, Fig. 5).As Fig. 3: front and rear wheel vehicle with steerable (gear connection shaft type) scheme drawing, 1. (front-wheel), 2. (steering shaft), 3. (front wheel spindle), 4. (gear adapter shaft), 5. (rack shaft), 6. pitman among the figure), 7. (spindle arm), 8. (trailing wheel), 9. (hind axle); As Fig. 4: when bearing circle (right-hand revolution) driven gear adapter shaft rotation of turning right makes rack shaft to left movement, make the wheel right-hand turning to scheme drawing; As Fig. 5: when bearing circle (anticlockwise direction rotation) the driven gear adapter shaft that turns left rotates rack shaft is moved right, make the wheel left-handed turning to scheme drawing.(bearing circle, transmission shaft, bevel gear etc. do not belong to the present technique scope and have just not drawn)
Two, in the front and rear wheel steering hardware of car oil cylinder or cylinder are housed, the sense of motion of direction of passage dish control fuel tap or air valve may command oil cylinder axle or cylinder axis removes to control wheel steering.As Fig. 6: 10. (oil cylinder or cylinder), 10. (oil cylinder axle or cylinder axis) scheme drawing are all arranged in the front and rear wheel steering hardware of car; As Fig. 7: when bearing circle right-hand turning (right-hand revolution) control fuel tap or air valve make oil cylinder axle or cylinder axis make the wheel right-hand turning to scheme drawing to left movement; As Fig. 8: when bearing circle left-handed turning (anticlockwise direction rotation) control fuel tap or air valve oil cylinder axle or cylinder axis are moved right make the wheel left-handed turning to scheme drawing.(parts such as bearing circle, fuel tap, air valve do not belong to the present technique scope and have just not drawn)
Three, also can make the front-wheel or any unidirectional the turning to of back crop rotation of car by the control system of oil cylinder cylinder.As Fig. 9: the car front-wheel is done divertical motion, and trailing wheel suspends and turns to; As Figure 10: back wheels of vehicle is done divertical motion, and front-wheel suspends and turns to.
The application of the most suitable compact car of above technology, yard tools car.
Claims (3)
1, the vehicle front and rear wheel all is equipped with steering hardware.
2, in the steering hardware of vehicle front and rear wheel oil cylinder or cylinder are housed all.
3, the steering hardware of vehicle front and rear wheel is connected by the gear adapter shaft.
