Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of simple in structure, and bearing capacity is strong, the drive shaft assembly of the locking that driving angle is large.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of drive shaft assembly of locking, comprises with lower member:
Internal spherical cage assembly, described internal spherical cage assembly receives from the power of engine mission output, is provided with the input coupling shaft for being connected with engine mission on internal spherical cage assembly;
External ball cage assembly, described external ball cage assembly receives the power of internal spherical cage and outputs to wheel position; On external ball cage assembly, be provided with the output coupling shaft for being connected with wheel position;
Intermediate connecting shaft, described intermediate connecting shaft connects internal spherical cage assembly and external ball cage assembly;
It is characterized in that: described input coupling shaft comprises and connects successively spline part, middle interconnecting piece and housing joint, described housing joint is provided with latch, on the longitudinal direction of latch, offer two locking apertures, between latch and housing joint, there is containing space, at containing space, bearing is installed.
The measure of taking for optimization such scheme specifically comprises:
In the drive shaft assembly of above-mentioned a kind of locking, the gap of described spline part is 0.75mm, and angle is 45 °.
In the drive shaft assembly of above-mentioned a kind of locking, on described middle interconnecting piece, be provided with flour milling fixed block.
In the drive shaft assembly of above-mentioned a kind of locking, described output coupling shaft comprises axially gradually open form spline and the fixed connecting piece linking into an integrated entity, described fixed connecting piece has four scallops, between two adjacent scallops, be formed with the draw-in groove with the phase clamping of wheel position, on the neutral position of fixed connecting piece, also offer the through hole with wheel portion phase locking.
In the drive shaft assembly of above-mentioned a kind of locking, the compression length of whole drive shaft assembly is 966 ± 3mm, and venting is of a size of 991mm.
Compared with prior art, the utility model has the advantage of the structure of input coupling shaft is improved and increased latch, by latch, just input coupling shaft and other accessory can be fixed like this, make drive shaft assembly in the situation that driving angle changes greatly, also can keep certain working stability, can adapt to complicated pavement state, and constant speed transmission is effective.
