Abstract
The utility model provides a junction box for a hydraulic drive shaft of a tractor, which is aimed for solving the problem that a hydraulic gear pump still rotates following a diesel engine when not in working, thereby increasing abrasion. The utility model comprises a hydraulic shaft which is connected with the hydraulic gear pump, a dynamic shaft of the diesel engine, and a junction box which is used for connecting two shafts, wherein the junction box consists of a shifting sleeve which is flexibly connected with the hydraulic shaft and a fixing sleeve which is connected with the dynamic shaft. According to different requirements, the shifting sleeve can axially move back and forth, the engagement and separation with the fixing sleeve can be realized, and the hydraulic gear pump can operate according to requirements, thereby effectively avoiding non-working abrasion of the hydraulic gear pump, the distributing valve and other component parts, prolonging service life, eliminating accident potential danger, enhancing driving safety, and reducing operation cost.
Description
The utility model relates to a kind of shaft joint, especially a kind of shaft joint that is used on the tractor with small four wheels hydraulic transmission axle.
Microtractor not only can transport goods, but also can constitute comparatively practical farm machinery with other mechanical engagement, therefore, is widely used in the rural area, various places.Using wider at mountainous rural area is tractor with small four wheels.Present existing tractor with small four wheels, because its hydraulic transmission axle links to each other with the diesel powered axle by shaft joint, so as long as diesel engine one work, will drive the mekydro pump work, cause this hydraulic gear pump to be in useless working state for a long time, both influenced the working life of tractor, accelerate the wearing and tearing of parts such as hydraulic gear pump, distributing valve again, make tractor with small four wheels exist accident potential such as leakage of oil, have a strong impact on traffic safety.Therefore, be necessary the hydraulic transmission axle shaft joint of existing tractor with small four wheels is improved,, guarantee the traffic safety of tractor to satisfy the needs of agricultural production.
The utility model is intended to overcome the deficiency of prior art, can close the hydraulic transmission axle shaft joint that can divide when not working when a kind of work is provided.
The utility model is realized by following technical proposal: it comprises the hydraulic axis that links to each other with hydraulic gear pump, the diesel powered axle, and the shaft joint that connects diaxon, it is characterized in that shaft joint is by constituting with the sliding set of hydraulic axis flexible connection and the fixed cover that links to each other with line shaft.Described fixed cover one end is provided with groove and double wedge, and the other end is provided with groove, so that link to each other with line shaft by key, fixed cover is rotated with line shaft.Described sliding set one end be provided with fixed cover on groove and the double wedge groove and the double wedge that match, so that under diesel engine drives, make the mekydro pump work with fixed cover engagement back, the other end of sliding set is provided with keyway, be used for matching with hydraulic axis, on sliding set, be provided with and stir groove, be used for shift fork or driving lever are placed groove, so that as required, sliding set is separated with fixed cover or mesh, thereby realize the work of hydraulic gear pump or stop.
The utility model compared with prior art has following advantage and effect: be made of fixed cover and sliding set respectively owing to be connected the shaft joint of hydraulic axis and line shaft, therefore, can be according to different needs, sliding set is moved back and forth vertically, the engagement of realization and fixed cover with separate, finally make hydraulic gear pump carry out work as required, effectively avoid hydraulic gear pump, the inoperative abrasion of parts such as distributing valve, prolong its working life, eliminate accident potential, improving traffic safety, reduce operating cost, is the shaft joint that a kind of comparatively desirable tractor with small four wheels mekydro pump shaft is used therefore.
Fig. 1 is the structural representation of the utility model.
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, 1 is hydraulic gear pump, 2 is the hydraulic axis that links to each other with hydraulic gear pump 1, this axle is made as splined shaft, 3 is line shaft, the one end links to each other with diesel engine, the other end is provided with key 31,4 is fixed cover, the one end matches with key 31 on the line shaft 3 by keyway 41, so that fixed cover 4 is fixed on the line shaft 3, and alternate groove 42 and the double wedge 43 of being provided with of the other end of fixed cover, 5 is sliding set, the splined shaft 2 of one end and hydraulic gear pump flexibly connects, the other end is alternate be provided with fixed cover on groove 42 and the double wedge 51 that matches of double wedge 43 and groove 52,53 for being located at the allocating slot that matches with shift fork or driving lever 6 on the sliding set 5, make sliding set 5 realize moving axially by shift fork or driving lever, thus the branch of control line shaft 3 and hydraulic gear pump 1 with close.
Claims (3)
1, a kind of tractor hydraulic transmission shaft shaft joint, it comprises the hydraulic axis that links to each other with hydraulic gear pump, the diesel powered axle, and the shaft joint that connects diaxon, it is characterized in that shaft joint is by constituting with the sliding set of hydraulic axis flexible connection and the fixed cover that links to each other with line shaft.
2, shaft joint according to claim 1 is characterized in that described fixed cover one end is provided with groove and double wedge, and the other end is provided with the groove that links to each other with line shaft.
3, shaft joint according to claim 1, it is characterized in that described sliding set one end be provided with fixed cover on groove and the double wedge groove and the double wedge that match, the other end is provided with the groove that links to each other with the axle of hydraulic gear pump, sliding set is provided with stirs groove.
