Abstract
The present invention relates to a propeller for a motor vehicle, particularly to a propeller for a cross-country vehicle. The present invention uses hydraulic force to control a rolling shape and change the size of a grounding area. The propeller for a motor vehicle is composed of a plurality of working chambers (3) and actuating rod bodies (2) arranged on a hydraulic supporting chamber body (1) along a radial direction, an annular grounding area block body (4), a valve (5), a pump (6) and a control element (7). The propeller for a motor vehicle rounds on a road surface during rotation so as to propel a vehicle to run. When the propeller for a motor vehicle rotates on the yielding soil, the actuating rod bodies (2) can drive the annular grounding area block body to become a stable rolling oblate circle through the hydraulic force. The present invention can enlarge the grounding area and enhance the cross country capability of the vehicle, and can be used for cross-country vehicles, engineering machines, agricultural machines, etc.
Description
The present invention relates to a kind of power actuated vehicle running gear, particularly overland vehicle running gear.
Existing wheeled car running gear because the ground contact area of wheel is little, ground pressure is big, it is dark to sink on soft soil, resistance is excessive, be difficult to by.The development and the application of wheeled car have been limited.Existing crawler belt running gear, ground contact area is big, and through performance is good, but complex structure, less economical.Adopt the vehicle of legged running gear,, can not be extensive use of because load is little, speed is low.Above technology has reflection in moral works " vehicle terramechanics " is continued in the village that mechanical industry is published.
The object of the present invention is to provide and a kind ofly can use the fluid power effect in motion, change the overland vehicle running gear of ground contact area size.
Running gear of the present invention supports cavity (1), the action body of rod (2), working cavity (3), annular ground plane block (4), valve (5) pump (6) and control piece (7) by fluid power and forms.It is characterized in that: on fluid power supporting cavity (1), radially be provided with several epitrochoidal chambers (3), device has the action body of rod (2) in each epitrochoidal chamber (3), the action body of rod (2) is connected with ground plane piece (8), and several ground plane pieces (8) form annular ground plane block (4).Fluid power supporting cavity (1) is provided with valve (5) pump (6) control piece (7).On fluid power supporting cavity (1), also be provided with knock hole (9) and some fastener holes (10).It can be connected on the axle drive shaft of vehicle, together rotate thereupon.One end of the action body of rod (2) is subjected to the effect of power fluid in epitrochoidal chamber (3) lining, the other end is connected with ground plane piece (8), and annular ground connection block (4) is to be formed by several ground plane pieces (8).It and ground effects produce tractive force.Each ground plane piece (8) is provided with tread pattern.Be arranged on valve (5) pump (6) and control piece (7) on the fluid power supporting cavity (1), be communicated with each epitrochoidal chamber (3), start the pressure and the volume of switching, Control work liquid.More than device is made by material known and method method.When running gear rotated on hardstand, the power fluid volume in each epitrochoidal chamber (3) equated, the extension elongation of the action body of rod (2) equates, driving annular ground plane block (4) becomes round as a ballly, promotes vehicle '.When running gear rotates on mellow soil, act on through valve (5) pump (6) control piece (7), power fluid total volume in all working chamber (3) reduces, the subaerial run body of rod (2) is constantly compressed, drive annular ground block (4) and form roll oblate, increased ground contact area.Running gear of the present invention, can use the stepless adjusting ground contact area of fluid power, can also act on through valve (5) pump (6) control piece (7), the keying in forced working chamber (3), make the action body of rod (2) drive the special shape that annular ground plane block (4) forms appointment, as the running gear of long flat, can strike as paddle wheel when in water, rotating, improve the water surface speed of land and water vehicle.Because liquid has vibration damping and shock damping action, running gear can absorption portion vibrate, and makes high vehicle speeds.Compared with prior art, it can improve the off-road capability of vehicle, is widely used in various overland vehicles, construction machinery and equipment and field machine etc.
The present invention will more clearly demonstrate from the accompanying drawing of the following example.
Accompanying drawing 1: the positive half-sectional view of power actuated vehicle running gear.
2: one devices of accompanying drawing have the vehicle of power actuated vehicle running gear.
Fig. 2 has described the vehicle that a device has the power actuated vehicle running gear, travels under cross-country status.On existing wheeled all-wheel drive vehicles, can be convenient to use this device.Promptly support knock hole (9) and firm hole (10) on the cavity (1), whole running gear is installed on the axle drive shaft of vehicle with fluid power.At the operator's compartment maneuver control device, the rolling form of running gear is adjusted.On the bottom and the top of epitrochoidal chamber (3), also be provided with inhibiting device respectively, the stroke up and down of the limit movement body of rod (2).Ground plane piece (8) can be made by elastomeric material, when vehicle in the desert, the marsh, when the land and water transition zone is travelled, the ground plane piece of interchangeable big width.Because the ground plane piece is a small members, has simplified and has deposited and mounting condition.
Claims (2)
1, a kind of power actuated vehicle running gear, overland vehicle running gear particularly, by fluid power supporting cavity (1), the action body of rod (2), working cavity (3), annular ground plane block (4), valve (5) pump (6) and control piece (7) are formed, it is characterized in that: on fluid power supporting cavity (1), radially be provided with several epitrochoidal chambers (3), device has the action body of rod (2) in each epitrochoidal chamber (3), the action body of rod (2) is connected with ground plane piece (8), several ground plane pieces (8) are formed annular ground plane block (4), fluid power supporting cavity (1) is provided with valve (5) pump (6) control piece (7), and fluid power supporting cavity (1) is provided with knock hole (9) and some fastener holes (10).
2, power actuated vehicle running gear according to claim 1 is characterized in that: at the middle part of ground plane piece, be provided with and move body of rod bonded assembly connecting device.
