The brake mechanism is characterized in that in the gearbox, an intermediate gear, clutch gears and internal gear covers are assembled on an intermediate shaft; the intermediate gear with transfer function obtains power through meshed with the previous gear and is joined with the clutch gears to transmit power to a left traveling mechanism and a right traveling mechanism; when the left and the right clutch gears are jointed with the intermediate gear at the same time, the traveling mechanisms walk straightly; when the left and the right clutch gears are separated from the intermediate gear and jointed with the left and the right internal gear covers, the traveling mechanisms stop walking; when the left clutch gear is separated from the intermediate gear and jointed with the left internal gear cover, the machine turns left; and when the right clutch gear is separated from the intermediate gear and jointed with the right internal gear cover, the machine turns right.
Description
Technical field
The utility model relates to a kind of grain header gearbox skidding mechanism, is applied on the small harvester, under the grain header normal operating conditions, can realize rigidity skidding and the left and right function that turns to.
Technical background
General grain header is that the form by friction plate realizes complete machine left and right turning to and skidding finds that through overtesting because the friction plate brake weight is not enough, can cause skidding unreliable, it is dumb to turn, and radius of turn is big.
Summary of the invention
The purpose of this utility model is to provide a kind of skidding mechanism, adopts the form of rigidity braking, replaces the original form that adopts friction disc brake.The utility model is applied to after the transfer gear of grain header gearbox, respectively the left and right driving of running gear is carried out skidding separately, has improved the reliability of skidding, has reduced the radius of turn of grain header, has improved the turning flexibility of grain header.
Technical solution of the present utility model is such: comprising: casing, jackshaft, idler gear, clutch gear, internal tooth wheel cap, travelling gear, spring, it is characterized in that: entire mechanism is divided into that left lateral is walked drive part and right lateral is walked drive part, idler gear and two clutch gears and two internal tooth wheel caps are assemblied on the jackshaft jointly, idler gear mediates, two clutch gears lay respectively at the both sides of idler gear, two internal tooth wheel caps then are contained in the outer face of both sides clutch gear respectively, are equipped with spring between clutch gear and internal tooth wheel cap.
The footpath upwards the clutch gear of the right and left radial teeth respectively with the steering spindle of the right and left on travelling gear engagement clutch.
The left and right sides tooth-shape structure of axially going up idler gear respectively with the tooth-shape structure engagement clutch of clutch gear.
Axially go up the tooth-shape structure engagement clutch of the tooth-shape structure and the internal tooth wheel cap of clutch gear.
The utility model has the advantages that the form that adopts the rigidity braking, replace the original form that adopts friction disc brake.In gearbox, on jackshaft, be equipped with idler gear, clutch gear, internal tooth wheel cap, wherein, idler gear is by obtaining power with the upper level gear meshing, by with the engaging of clutch gear, realize left, right lateral walks mechanism's transferring power, has the transfer function.When left and right clutch gear engages with idler gear simultaneously, the running gear straight line moving, when left and right clutch gear separates with idler gear simultaneously and engages with left and right internal tooth wheel cap, running gear realization parking.When left side clutch gear separates with idler gear, and when engaging with left side internal tooth wheel cap, running gear realizes.When the right clutch gear separates with idler gear, and when engaging with the right internal tooth wheel cap, running gear realizes turning right.Simple in structure, easy to manufacture, easy to use, safe and reliable, realize the hommization operation.

Among Fig. 1～Figure 11, the tooth-shape structure (302) of the tooth-shape structure (201) of jackshaft (1), idler gear (2), clutch gear (3), internal tooth wheel cap (4), travelling gear (5), spring (6), casing (10), idler gear, the tooth-shape structure (301) of clutch gear, clutch gear, the tooth-shape structure (401) of internal tooth wheel cap.
Embodiment
Most preferred embodiment of the present utility model is such, with reference to accompanying drawing: as shown in Figure 1 and Figure 2, on jackshaft (1), be equipped with both sides that idler gear (2), two clutch gears (3) be assemblied in idler gear (2) respectively, both sides that two internal tooth wheel caps (4) are assemblied in gearbox respectively in the centre position, between clutch gear (3) and internal tooth wheel cap (4), be equipped with spring (6).
. as Fig. 3～shown in Figure 11, the both sides of idler gear (2) all are furnished with tooth-shape structure (201).
As Fig. 4, Fig. 5, shown in Figure 6, the both sides of clutch gear (3) all are furnished with tooth-shape structure (301), (302).During straight line moving, as shown in Figure 2, idler gear (2) by with the engagement of upper level travelling gear (5), accept power, under the effect of spring force, the clutch gear of both sides (3) abuts against the both sides of idler gear (2), and the tooth-shape structure (201) of idler gear (2) both sides and the engagement of the tooth-shape structure (301) of clutch gear (3) realize that promptly idler gear (2) is to clutch gear (3) transferring power.Clutch gear (3) then by the structure of its roller gear, to its next stage gear (5) transferring power, is realized straight line moving.During Brake stop, as shown in Figure 8, separate with idler gear (2) by stirring clutch gear (3), the power of clutch gear (3) is cut off, continue to stir clutch gear (3) and be close to internal tooth wheel cap (4), when tooth-shape structure (401) engagement of the tooth-shape structure (302) of the another side of clutch gear (3) and internal tooth wheel cap (4), clutch gear (3) stops operating, simultaneously, because of clutch gear (3) its roller gear structure in total travel keeps engagement with its next stage travelling gear (5) all the time, realized the rigidity braking brake.During turning, as Fig. 9, shown in Figure 10, by stirring the wherein clutch gear of a side (3), it is separated with idler gear (2), cut off its power source, at this moment do not break away from engagement with idler gear (2) because of opposite side clutch gear (3), power is excision not, it continues to next stage gear transmission power, and promptly this side will walk on, and realize turning.And, do not continue to be pushed the position that combines with internal tooth wheel cap (4) if be cut off the clutch gear (3) of power one side, promptly do not make this side realize the rigidity brake, car load will be realized big the turning.When the clutch gear that is cut off power one side (3) is continued to push the position that combines with internal tooth wheel cap (4), promptly this side realizes rigidity brake, and car load will be realized little turning.
