Abstract
The utility model relates to a steering mechanism for controlling the swing of a priority valve by a steering wheel of a tractor, comprising the steering wheel, a steering upright post, a cross universal joint, a bracket, a lower shaft, a torsional spring, a connecting disc, a control disc of the priority valve, a baffle, a rotating pin shaft, a priority valve assembly and the like, wherein the steering wheel is connected with the steering upright post by a spline, the steering upright post is connected with the cross universal joint by the spline, and the cross universal joint is connected with the lower shaft by the spline; the lower shaft is connected with the control disc of the priority valve by a straight key; and the B end of a swing rod on the priority valve assembly is arranged inside a groove C on the control disc of the priority valve all the time. When the steering wheel is rotated, the steering upright post, the cross universal joint and the lower shaft are driven to rotate by the steering wheel, the control disc of the priority valve is driven to rotate by the lower shaft, and the B end of the swing rod on the priority valve assembly is arranged inside the groove C onthe control disc of the priority valve all the time, so that the swing rod on the priority valve assembly is driven to rotate around the point O to swing; the corresponding mechanism is controlled bythe swing of the swing rod, so that steering can be realized; when the steering wheel is released, under the action of a torsional spring, the steering wheel automatically returns to the neutral position, and steering is stopped.
Description
(1) technical field
The utility model belongs to the trac. field, relates to a kind of trac. bearing circle control priority valve swing steering hardware.
(2) background technology
At present, the steering control mechanism of the trac. of domestic production, construction machinery and equipment mainly contains:
(1) rod-pulling type: chaufeur is by pulling pull bar control priority valve, thereby the pilot control corresponding mechanism reaches the purpose that turns to.
(2) handle type: chaufeur direct control priority valve handle, the pilot control corresponding mechanism reaches the purpose that turns to.
Though it is easy that above-mentioned maneuverability pattern is handled, wheel steering mechanism is more suitable for the manipulation custom of chaufeur.Bearing circle control priority valve swing steering hardware is the swing by chaufeur steering wheel rotation control priority valve, promptly the swing of priority valve is converted into the rotation of bearing circle, thus the mechanism that realization turns to.This steering unit can make the chaufeur handling maneuver convenient, comfortable.
(3) utility model content
The purpose of this utility model is to provide a kind of trac. bearing circle control priority valve simple in structure, that control comfort is comfortable to swing steering hardware.
The technical solution of the utility model is: trac. bearing circle control priority valve swing steering hardware mainly comprises bearing circle 1, turns to column 2, turns to column sleeve pipe 3, universal joint cross 4, support 5, lower shaft 6, torsion spring 7, terminal pad 8, bearing 9, pilot control dish 10, base shrouding 11, base 12, caging bolt 13, baffle plate 14, rotating pin 15, priority valve assembly 16.It is characterized in that: bearing circle 1 turns to the column 2 of turning to of column sleeve pipe 3 to link by spline with being equipped with, turn to column sleeve pipe 3 to link by rotating pin 15 and support 5, turn to column 2 and universal joint cross 4 to link by spline, universal joint cross 4 and lower shaft 6 link by spline, lower shaft 6 links by flat key and terminal pad 8, baffle plate 14, below lower shaft 6, link, and the swing arm B on the priority valve assembly 16 end is all the time in the groove C on priority valve control panel 10 by flat key and pilot control dish 10.
In the middle of terminal pad 8, baffle plate 14 torsion spring 7 is housed, torsion spring 7 is fixing by caging bolt 13; Between lower shaft 6 and the base 12 bearing 9 is housed; Base shrouding 11 is equipped with in base 12 belows.
The utility model patent can reach following beneficial effect: adopts such scheme can make the chaufeur steering wheel rotation control the swing of priority valve, promptly the swing of priority valve is converted into the rotation of bearing circle, thus the mechanism that realization turns to.This steering unit can make the chaufeur handling maneuver convenient, comfortable, is more suitable for handling custom.
(4) description of drawings
Fig. 1 is the utility model trac. bearing circle control priority valve swing steering hardware constructional drawing.
Fig. 2 swings steering hardware A to view (removing the base shrouding) for the utility model trac. bearing circle control priority valve.
(5) specific embodiment
As shown in Figure 1 and Figure 2, trac. bearing circle control priority valve swing steering hardware mainly comprise bearing circle 1, turn to column 2,, universal joint cross 4, support 5, lower shaft 6, torsion spring 7, terminal pad 8, bearing 9, pilot control dish 10, base shrouding 11, base 12, caging bolt 13, baffle plate 14, rotating pin 15, priority valve assembly 16.Turn to the column 2 of turning to of column sleeve pipe 3 to link with being equipped with bearing circle 1 by spline, turn to column sleeve pipe 3 to link by rotating pin 15 and support 5, turn to column 2 and universal joint cross 4 to link by spline, universal joint cross 4 and lower shaft 6 link by spline, lower shaft 6 links by flat key and terminal pad 8, baffle plate 14, below lower shaft 6, link, and the swing arm B on the priority valve assembly 16 end is all the time in the groove C on priority valve control panel 10 by flat key and pilot control dish 10.
In the middle of terminal pad 8, baffle plate 14 torsion spring 7 is housed, torsion spring 7 is fixing by caging bolt 13; Between lower shaft 6 and the base 12 bearing 9 is housed; Base shrouding 11 is equipped with in base 12 belows.
When steering wheel rotation, bearing circle drives and to turn to column 2 to rotate, and drives the rotation of lower shafts 6 by universal joint cross 4, and be dynamically connected dish 8 and baffle plate 14 of the rotating band of lower shaft 6 rotates, thereby an end that drives torsion spring 7 rotates around lower shaft 6; Simultaneously, lower shaft 6 drives pilot control dishes 10 and rotates, and the B of the swing arm on the priority valve assembly 16 end is in the groove C on priority valve control panel 10 all the time, thereby the swing arm that drives on the priority valve assembly 16 is swung around the O point; The swing control corresponding mechanism of the swing arm on the priority valve assembly 6, thus realize turning to; Decontrol bearing circle, under the effect of torsion spring 7, bearing circle is got back to center position automatically, stops turning to.
