Abstract
The utility model relates to a universal joint which comprises an outer shaft, an inner shaft, a splined connection fork and a crossed shaft, wherein each of the outer shaft and the inner shaft is a hollow square tube structure, the inner shaft is inserted into the outer shaft to form a nested joint, the top ends of the outer and the inner shafts are connected with the splined connection fork respectively, and the splined connection fork is connected with the outer and the inner shafts through the crossed shaft. The universal joint has the advantages of reasonable design, convenience in use, low material consumption and the like.
Description
Technical fieldThe utility model relates to a kind of connection set, especially a kind of Motor Vehicle connection set.
Background techniqueKnown, universal joint is the parts of realizing varied angle transferring power between rotating shaft.Wherein, rigid universal joint is divided into again nonconstant velocity universal joint, near constant velocity universal joint and constant velocity universal joint.Cross shaft rigid universal joint in nonconstant velocity universal joint is simple in structure, the larger angle of cut is arranged between reliable operation and the diaxon that allows to connect, uses the most general on automobile.But the interior axle of present cardan universal joint adopts solid construction, the waste steel.
Summary of the inventionThe purpose of this utility model is to provide and a kind ofly reduces that cost, consumptive material are few, widely used universal joint.
The utility model mainly comprises outer shaft, interior axle, spline joint fork and cross axle, and described outer shaft and interior axle are the square hollow pipe structure, and interior axle inserts the nested connection of outer shaft; Outer shaft with in the top of axle connect respectively the spline joint fork, described spline joint fork is connected with outer, interior axle by cross axle.
Compared with the prior art, the beneficial effects of the utility model are: reasonable in design, convenient and practical, saving material, can reduce manufacture cost greatly.
Description of drawings
Fig. 1 is stereochemical structure sketch of the present utility model.
Fig. 2 is cross axle structure figure of the present utility model.
Fig. 3 is spline joint fork structural drawing of the present utility model.
Drawing reference numeral: 1 be outer shaft, 2 for interior axle, 3 for spline joint fork, 4 be cross axle.
EmbodimentIn stereochemical structure sketch of the present utility model shown in Figure 1, mainly comprise outer shaft 1, interior axle 2, spline joint fork 3 and cross axle 4, described outer shaft and interior axle are the square hollow pipe structure, and interior axle inserts the nested connection of outer shaft; Outer shaft with in the top of axle connect respectively the spline joint fork, described spline joint fork is connected with outer, interior axle by cross axle.
Outer shaft---fork shaft part material all adopts the casting of DIN structural steel to form, the shaping after annealing is in order to strengthen hardness, improve torsional rigidity and improved the interchangeability convenient for maintaining, the boss of the thick 2.5mm of the nested long 15mm of hollow shaft jointing, be convenient to dismounting, in case hollow shaft part is separated during because of operation with the fork shaft part, only needs a disassembled simply just can keep in repair by arc welding.
Interior axle---material adopts the casting of DIN structural steel to form with outer shaft, and in process of production, the processing of axle bothers relatively, and according to our design original intention, the hollow parts of interior axle and outer shaft is made by the extraordinary square tube of heavy wall, so increased the durable degree of universal joint, quality is guaranteed; And the inner shaft, outer shaft hollow parts is all that the surrounding type arc welding is connected with fork shaft.
Spline joint fork---spheroidal graphite cast iron adopts sand casting process to form, and matching tractor uses, and keyway is wide is 6mm groove depth 3mm, six spline keyways, and keyway processes by slotting machine.
Cross axle---forging is processed by annealing process and is formed.Be criss-cross four screw threads that little axle one end goes out through machined into, the other end car has the ladder that rolling bearing can be installed, so just can easy disassembly, greatly improved working efficiency.
Anticreep locating stud---blank forging simultaneously an end process thick for the 2mm diameter be the boss of 12mm with locking pin, then the other end passes maximum plain line to get diameter is that the last low-temperature tempering of through hole of 2.5mm is with the raising mechanical property.During use, the cylndrical surface just in time overlaps with the concave surface of the bottleneck of splined shaft.
Bayonet lock, washer sets---Ordinary Steel can satisfy job requirement as raw material, through drawing, stamping process production.The bayonet lock washer sets is the combination that prevents that the anticreep locating stud from moving, and the slip that packing ring has produced when having avoided universal joint work and cause the direct shock of bayonet lock is caused damage to it only needs to penetrate the long-armed bending of circular hole to bayonet lock and gets final product during installation.
Described cross axle is fixing with coordinating of spline joint fork, inner shaft, outer shaft when dispatching from the factory, and described anticreep locating stud and bayonet lock washer sets are all to install when work.
