Abstract
The utility model belongs to the technical field of machine parts, and provides a drive shaft assembly provided with a protection structure. The drive shaft assembly comprises the following components: an inner ball cage assembly, an outer ball cage assembly and a middle connecting shaft, wherein an output connecting shaft, which is connected to a wheel part, is arranged on the outer ball cage assembly; a flange used for preventing interference with other parts is arranged on the outer end face of the outer ball cage assembly, and a tightening ring is arranged on the flange. The drive shaft assembly has the advantages that tightness of the drive shaft assembly and other components is guaranteed through the flange and the tightening ring; meanwhile, the tightening ring has elasticity, so that a certain buffer function is implemented, the noise is prevented, furthermore, the whole drive shaft assembly can keep a certain working stability under the condition of large change of a transmission angle, the drive shaft assembly can adapt to the complicated road surface condition, and a constant-speed transmission effect is good.
Description
Technical field
The utility model belongs to mechanical fitting technical field, relates to a kind of drive shaft assembly with safeguard structure.
Background technique
In order to make automobile power transmission, all can use drive shaft assembly, adopting at present maximum is Rzeppa type drive shaft assembly, no matter this kind of drive shaft assembly is that circular arc alley or liner ball road have all solved constant speed transmission problem preferably, and it is large to transmit operating angle, and efficiency is high.Automobile on the way travels, and the situation of encountering is quite complicated, and it is unreasonable that present drive shaft assembly does not generally all have safeguard structure or safeguard structure to arrange, and so not only can cause with other accessory and can interfere, and coordinates and closely can not cause noise yet simultaneously.
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, coordinates the drive shaft assembly with safeguard structure closely with other accessory.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of drive shaft assembly with safeguard structure, comprises with lower member:
Internal spherical cage assembly, described internal spherical cage assembly receives from the power of engine mission output;
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: on the exterior edge face of described external ball cage assembly, for preventing and the rib of other accessory interference, tight circle is set on described rib.
The measure of taking for optimization such scheme specifically comprises:
In above-mentioned a kind of drive shaft assembly with safeguard structure, described tight circle is U font, and closely the length of circle is 6～9mm.
In above-mentioned a kind of drive shaft assembly with safeguard structure, described output coupling shaft comprises axially gradually open form spline and the fixed connecting piece that link into an integrated entity, described fixed connecting piece has four scallops, between two adjacent scallops, be formed with and the draw-in groove of wheel position phase clamping, on the neutral position of fixed connecting piece, also offer the through hole with wheel portion phase locking.
In above-mentioned a kind of drive shaft assembly with safeguard structure, on the surface of described intermediate connecting shaft, internal spherical cage assembly surface and external ball cage assembly surface all have the plastic-blasting layer for preventing from top layer from getting rusty.
In above-mentioned a kind of drive shaft assembly with safeguard structure, the compression length of whole drive shaft assembly is of a size of 677.4 ± 3mm, and venting size is long is 703mm.
Compared with prior art, the utility model has the advantage of by rib and tight circle and guaranteed the tightness coordinating with other assembly, simultaneously owing to closely enclosing and thering is elasticity, therefore also reached certain buffer function, thereby prevent noise, whole 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.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this drive shaft assembly with safeguard structure;
Fig. 2 is the structural representation of fixed connecting piece.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
