Abstract
The invention provides a traveling device of a tractor, in particular to a paddy wheel which is made of metal. The paddy wheel can produce the friction in a paddy field to be consistent with that on a hard pavement, so that the tractor can obtain the traction force in the paddy field which is consistent with that on the hard pavement; and moreover the tractor dual-purpose paddy wheel is convenient to operate and small in steering resistance. The tractor dual-purpose paddy wheel is applicable to the traveling machinery which moves on the paddy field or on the hard pavement and on the pavement falling in between the paddy field and the hard pavement.
Description
Technical field:
The present invention relates to a kind of running gear of metal-made trac., a kind of metal-made wheel mainly is used as driving wheel specifically.
Background technology:
The dual-purpose wheel of assembling on the trac. now when walking in the paddy field, easily skidded, and the tractive force of trac. diminished, so that can not walk.At the fragile wheel of hard surfacing walking, turn in addition difficulty.Skidding is because the friction force between paddy field wheel and the ground has diminished, its reason be paddy field wheel surperficial jam native mud.Under normal circumstances, the walking of trac. overcomes between driving wheel and the ground friction force by the power on the trac. and walks, that is to say that the friction force between driving wheel and the ground is less, the tractive force of trac. is just less, vice versa, on the paddy field wheel behind the jam soil mud, the native mud effect of jam on paddy field wheel disperseed the on the ground pressure of plane of action of former paddy field wheel on the ground, so the friction force on paddy field wheel and ground diminishes, and jam on paddy field wheel native mud and the friction coefficient on ground less than the friction coefficient on former paddy field wheel and ground, so behind the paddy field wheel jam soil mud and the friction force between the ground just become than jam soil mud is not little, appearance is skidded, and causes the tractive force of trac. to reduce.At the fragile wheel of hard surfacing walking, because the area of contact on paddy field wheel and ground is single, there is not elasticity, no matter trac. applies great pressure to paddy field wheel, area of contact and the contact position of paddy field wheel road pavement are certain, can not change, so paddy field wheel damages and cornering resistance is large thereupon.The radially area of paddy field wheel outside is large in addition, and the native mud area of contact when turning to and in the paddy field is large, so resistance turns to greatly difficulty.
Goal of the invention:
A kind of paddy field wheel is provided, paddy field wheel can be produced and paddy field wheel the same friction force on hard surfacing in the paddy field with ground, when even trac. is walked in the paddy field, obtain with trac. at the hard surfacing the same large tractive force of walking, and easy to operate be that cornering resistance is little.
Summary of the invention:
Trac. double-duty paddy field wheel of the present invention comprises wheel hub. spoke. and wheel rim. the formations such as tooth slice and wheel outer ring.Usually wheel rim is by bonding jumper one circumference to be set to consist of, and the inside connects spoke. wheel hub.The outside splits some tooth slices equably, and the tooth slice outside arranges the wheel outer ring again.Specific requirement is: 1. the axial width of taking turns the outer ring is greater than or equals the axial width of wheel rim.The direct contact surface that can enlarge paddy field wheel and ground is long-pending, prevents that paddy field wheel is excessively sagging in the paddy field; 2. wheel rim. the wheel outer ring lay respectively at tooth slice in. the middle, outer end.Can make like this wheel outer ring bear separately paddy field wheel and from the pressure of paddy field wheel, the native mud of wheel rim in the paddy field is exerted pressure to ground, the friction force on paddy field wheel and ground is not reduced; 3. the axial width of tooth slice will be equal to or greater than the axial width of wheel outer ring more than 1 times.Can additionally strengthen paddy field wheel in the paddy field with the area of contact of earth, increase friction force; 4. wheel rim and wheel outer ring are separately more than or equal to the distance of radial width of wheel outer ring.Earth is to the resistance of its both sides when its effect can reduce paddy field wheel and turns to and in the paddy field; 5. tooth slice is a flat sheet, and inner direction is consistent with the center-point of paddy field wheel.Its effect is: can make to be attached to the earth between the adjacent wheels gear piece on the paddy field wheel, be separated in the process that paddy field wheel rotates, to reduce the additional weight of paddy field wheel, be beneficial to walking; 6. the outer end of tooth slice is high in the middle of being. and the arc that both sides are low, middle height is less than 1/10 of the axial width of tooth slice.Its effect is: the both sides of tooth slice do not contact the road surface in the time of on hard surfacing, reduce cornering resistance; 7. the outer end radian of wheel outer ring is consistent with the outer end radian of tooth slice.Its effect is: can make paddy field wheel through differing texture. during the ground of different dip plane, can automatically regulate area of contact and contact position with ground, to keep constant with the friction force on ground.
Useful effect:
Trac. double-duty paddy field wheel provided by the invention is walked in the paddy field and can be obtained and the same friction force of walking at hard surfacing.That is to say that trac. can have consistent tractive force on paddy field and hard surfacing, and cornering resistance is less than existing double-duty paddy field wheel.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is radial structure scheme drawing of the present invention.
Fig. 2 is axial arrangement scheme drawing of the present invention.
1-wheel rim among Fig. 1 .2, the 2-tooth slice, 3-takes turns the outer ring.
The specific embodiment:
Shown in accompanying drawing 1 embodiment:. wheel rim (1) and wheel outer ring (3) are separately more than or equal to the distance of radial width of wheel outer ring (3); Earth is to the resistance of its both sides when its effect can reduce paddy field wheel and turns to and in the paddy field; Tooth slice (2) is a flat sheet, inner direction is consistent with the center-point of paddy field wheel, and its effect is: can make to be attached to the earth between the adjacent wheels gear piece (3) on the paddy field wheel, be separated in the process that paddy field wheel rotates, to reduce the additional weight of paddy field wheel, be beneficial to walking.
Shown in accompanying drawing 2 embodiment: the axial width of wheel outer ring (3) is greater than or equals the axial width of wheel rim (1); The direct contact surface that can enlarge paddy field wheel and ground is long-pending, prevents that paddy field wheel is excessively sagging in the paddy field; The axial width of tooth slice (2) is greater than the axial width of wheel outer ring (3) more than 1 times; Can additionally strengthen paddy field wheel in the paddy field with the area of contact of earth, increase friction force; The outer end of tooth slice (2) is high in the middle of being. and the height in the middle of the low arc in both sides is less than 1/10 of the axial width of tooth slice (2); Its effect is: in the time of on hard surfacing, the both sides of tooth slice (2) do not contact the road surface, reduce cornering resistance; The outer end radian of wheel outer ring (3) is consistent with the outer end radian of tooth slice.Its effect is: can make paddy field wheel through differing texture. automatically regulate area of contact and contact position with ground during the ground of different dip plane, to keep constant with the friction force on ground.
