Abstract
The utility model belongs to the technical field of car drive accessories and provides a fixed input structure of an inner joint. The structure comprises an input main shaft, wherein the input main shaft comprises a spline part, a middle part and a connecting part, the spline part is connected to a gear of a gear box through a spline, a locking frame is arranged on the connecting part, and a pressing ring is sleeved on the middle part and provided with a protective ring. The structure has the advantages that the input main shaft is locked through the locking frame, the stability of the input main shaft is good during rotation, the bearing capacity is improved, the structure is suitable to cars of high-torque and high strength requirements, the input main shaft and other parts are separated through the protective ring, and the stability of the operation of the input main shaft can be guaranteed.
Description
Technical field
The utility model belongs to Automobile drive accessory technical field, relates to a kind of fixedly input structure of internal spherical cage.
Background technique
The ransaxle assembly is one of vitals of car transmissions, and forerunner's Automobile drive axle assembly of prior art generally is connected transmitting torque by input shaft with the automobile gearbox translation interface, and input shaft and ransaxle assembly internal spherical cage are connected as a single entity.This kind structure is relatively less than normal because of the input shaft size, bearing load is less, and poor stability, making precision and technique all has higher requirements, high to input shaft and the grease proofing technological requirement of gear box casing interface position antiseepage, manufacture cost is higher, and the vehicle that requires for high moment of torsion high strength, and there is certain hidden danger in this kind structure.
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, guarantees the fixedly input structure of the internal spherical cage of ransaxle assembly operation stability.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of fixedly input structure of internal spherical cage, comprise entering spindle, it is characterized in that, described entering spindle comprises spline part, intermediate portion and joint, the gear of described spline part and gearbox passes through spline joint, be provided with lock bracket on described joint, be set with pressure ring on intermediate portion, on described pressure ring, guard ring is installed.
Specifically comprise for optimizing the such scheme Adopts measure:
At the fixedly input structure of above-mentioned a kind of internal spherical cage, rubber o-ring is installed also on described intermediate portion.
At the fixedly input structure of above-mentioned a kind of internal spherical cage, have the bearing support that is connected as a single entity with it on described lock bracket, between described bearing support and joint, bearing is installed, be provided with dust ring on the right side of bearing.
Compared with prior art, the utility model has the advantage of entering spindle is locked by lock bracket, make entering spindle good stability when rotating, improved bearing capacity, be adapted at the vehicle use that high moment of torsion high strength requires, guard ring is isolated entering spindle and other part simultaneously, guarantees the stability of entering spindle operation.
Description of drawings
Fig. 1 is the schematic diagram of the fixedly input structure of this internal spherical cage.
Embodiment
