Description
Technical field
The utility model belongs to the tractor field, relates to the reciprocal operating mechanism of a kind of used with tractor differential lock shift fork.
Background technique
Traditional used with tractor differential lock fork control mechanism, adopt the differential lock shift fork of band V-shaped part to be equipped with return spring, drive the declutch shift shaft revolution by pedal, make affixed superincumbent cotter pin promote the V-shaped part shift fork and drive differential lock grafting differential mechanism, thereby realize differential effect.And the separation of its grafting effect is complete in unclamping the returning place force realization of return spring behind the pedal.This structure assembly process, the pre-pressing force that need artificially resist return spring, while construction opening pin, and need professional assembly fixture, the loaded down with trivial details effort of operating process.Assembling tailboard steering force size depends on the rigidity property of spring own fully, can't adjust it.Because the instability of the rigidity of spring own causes pedal effort to vary.In addition, along with increasing of box of tricks access times, the spring rate variation, spring-back force descends, and differential lock clamping stagnation fault easily takes place.And fault betides in the back axle casing, and maintenance need be taken gearbox apart and carried out, and workload is big, the maintenance cost height.
The model utility content
The purpose of this utility model is to provide a kind of reliable in structure, and easy disassembly, dynamics is adjustable, the reciprocal operating mechanism of used with tractor differential lock shift fork of easy maintenance.
The utility model can be achieved through the following technical solutions above-mentioned purpose: the reciprocal operating mechanism of used with tractor differential lock shift fork comprises: housing, declutch shift shaft, differential lock, reciprocating type shift fork, bearing pin, cotter pin, resilient key, differential mechanism, driven rocking arm, returning pull-spring, connecting rod, returning place force are adjusted plate, initiatively rocking arm, pedal-rod, bearing, pedal; Declutch shift shaft passes through the housing bore freely-supported on housing, resilient key is plugged on the declutch shift shaft, differential lock is socketed on the differential casing, and be plugged in the differential mechanism pin-and-hole by pin, reciprocating type shift fork is connected on the declutch shift shaft by the shift fork borehole jack, and by prong and differential lock socket, bearing pin is plugged in the spiral chute of the pin-and-hole of declutch shift shaft and reciprocating type shift fork, and fix by cotter pin, driven rocking arm is fixed on the declutch shift shaft, return spring is articulated between driven rocking arm and the returning place force regulator plate, and pull bar is articulated between driven rocking arm and the initiatively rocking arm, and returning place force is adjusted plate and is fixed on the pull bar, initiatively rocking arm is fixed on the pedal-rod, the pedal-rod freely-supported is on bearing, and bearing is fixed on the tractor seat plate, and pedal is fixed on the pedal-rod.
The utility model can reach following good effect: after adopting the utility model, under the prerequisite that satisfies the differential lock functional requirement fully, because shift fork possesses helical groove structure, can realize the reliable locking of differential lock and separate, easily damaged parts is arranged in outside, the difficulty that reduces maintenance and change, save the maintenance cost, return spring is by the round setting type, can realize the steering force adjustment, improve and handle comfort level, prolong the Acceptable life of spring simultaneously, can carry out the improvement of local adaptation's property according to concrete arrangement requirement at different type of machines, can satisfy the requirement of each power section type differential lock versatility.
Description of drawings
Fig. 1 is the structural representation of the reciprocal operating mechanism of the utility model used with tractor differential lock shift fork.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.As shown in Figure 1, the reciprocal operating mechanism of used with tractor differential lock shift fork comprises: housing 1, declutch shift shaft 2, differential lock 3, reciprocating type shift fork 4, bearing pin 5, cotter pin 6, resilient key 7, differential mechanism 8, driven rocking arm 9, returning pull-spring 10, connecting rod 11, returning place force are adjusted plate 12, initiatively rocking arm 13, pedal-rod 14, bearing 15, pedal 16.Declutch shift shaft 2 passes through the housing bore freely-supported on housing 1, and by resilient key 7 axial limitings, differential lock 3 is socketed on differential mechanism 8 housings, and be plugged in differential mechanism 8 pin-and-holes by pin, reciprocating type shift fork 4 is connected on the declutch shift shaft 2 by the shift fork borehole jack, and by prong and differential lock 3 sockets, bearing pin 5 is plugged in declutch shift shaft 2 pin-and-holes and reciprocating type shift fork 4 spiral chutes, and it is fixing by cotter pin 6, driven rocking arm 9 is welded on the declutch shift shaft 2, returning pull-spring 10 is articulated between driven rocking arm 9 and the returning place force regulator plate 12, and pull bar 11 is articulated between driven rocking arm 9 and the initiatively rocking arm 13, and returning place force is adjusted plate 12 and is welded on the pull bar 11, initiatively rocking arm 13 is welded on the pedal-rod 14, pedal-rod 14 freely-supporteds are on bearing 15, and bearing 15 is fixed on the tractor seat plate, and pedal 16 is welded on the pedal-rod 14.
