Abstract
The utility model discloses a kind of trailing wheel differential attachment based on unilateral bearing, form primarily of gear, main shaft, trailing wheel, wheel hub, bearing, screw and unilateral bearing, described gear is arranged on main shaft central authorities, described main shaft is through unilateral bearing and bearing inner race interference fit, described unilateral bearing outer ring interference fit is arranged on inside wheel hub, described bearing outer ring interference fit is arranged on outside wheel hub, and described wheel hub relies on screw to connect trailing wheel.Described gear provides power for main shaft, drives rear wheel, and vehicle front-wheel steer causes trailing wheel friction different, under unilateral bearing effect, the side rear wheel rotation speed that resistance is large is slow, and the side rotating speed that resistance is little is fast, realize the differential motion of trailing wheel, complete turn inside diameter.The beneficial effects of the utility model are as follows: adopt unilateral bearing to realize trailing wheel differential motion, structure is simple, and two-wheeled can be arranged on the same axis, and can be used for, on the dilly compared with side crops industry or precise motion, has higher promotional value.
Description
Technical field
The utility model relates to a kind of trailing wheel differential attachment, particularly a kind of trailing wheel differential attachment based on unilateral bearing.
Background technique
Vehicle generally adopts the mode of front-wheel steer trailing wheel differential motion to realize turning.Large vehicle due to load comparatively large, the normal trailing wheel differential attachment adopted based on differential mechanism, apparatus expensive, has higher requirement to the coaxality of two-wheeled.The utility model adopts unilateral bearing to realize trailing wheel differential motion, and structure is simple, and two-wheeled can be arranged on the same axis, and can be used for, on the dilly compared with side crops industry or precise motion, has higher promotional value.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed for prior art, provide a kind of trailing wheel differential attachment based on unilateral bearing, structure is simple, and two-wheeled can be arranged on the same axis, can be used for, on the dilly compared with side crops industry or precise motion, having higher promotional value.
Its technological scheme is: a kind of trailing wheel differential attachment based on unilateral bearing, form primarily of gear, main shaft, trailing wheel, wheel hub, bearing, screw and unilateral bearing, described gear is arranged on main shaft central authorities, described main shaft is through unilateral bearing, described main shaft and bearing inner race interference fit, described unilateral bearing outer ring interference fit is arranged on inside wheel hub, and described bearing outer ring interference fit is arranged on outside wheel hub, bearing face and spindle end are in the face of neat, and described wheel hub relies on screw to connect trailing wheel.
Described gear provides power for main shaft, drives rear wheel, and vehicle front-wheel steer causes trailing wheel friction different, under unilateral bearing effect, the side rear wheel rotation speed that resistance is large is slow, and the side rotating speed that resistance is little is fast, realize the differential motion of trailing wheel, complete turn inside diameter.
Accompanying drawing explanation
Accompanying drawing 1 is overall structure schematic diagram of the present utility model.
Accompanying drawing 2 is partial structurtes schematic diagram of the present utility model.
In upper figure: gear 1, main shaft 2, trailing wheel 3, wheel hub 4, bearing 5, screw 6, unilateral bearing 7.
Embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model forms primarily of gear 1, main shaft 2, trailing wheel 3, wheel hub 4, bearing 5, screw 6 and unilateral bearing 7, described gear 1 is arranged on main shaft 2 central authorities, described main shaft 2 is through unilateral bearing 7, described main shaft 2 and bearing 5 inner ring interference fit, described unilateral bearing 7 outer ring interference fit is arranged on inside wheel hub 4, described bearing 5 outer ring interference fit is arranged on outside wheel hub 4, and bearing 5 end face aligns with main shaft 2 end face, and described wheel hub 4 relies on screw 6 to connect trailing wheel 3.
Described gear 1 provides power for main shaft 2, drives trailing wheel 3 to rotate, and vehicle front-wheel steer causes trailing wheel 3 friction different, under unilateral bearing 7 acts on, the side rear wheel rotation speed that resistance is large is slow, and the side rotating speed that resistance is little is fast, realize the differential motion of trailing wheel 3, complete turn inside diameter.
The beneficial effects of the utility model are: adopt unilateral bearing to realize trailing wheel differential motion, structure is simple, and two-wheeled can be arranged on the same axis, and can be used for, on the dilly compared with side crops industry or precise motion, has higher promotional value.
