Abstract
The utility model relates to a tripod uniform speed universal joint used on an automobile. Mainly, a spherical surface lining ring is arranged between a needle roller and a spherical ferrule of an existing tripod uniform speed universal joint, the outer spherical surface thereof is matched with the inner diameter of the spherical ferrule, and the inner diameter is the same as that of an original spherical ferrule. The utility model improves the performance of an original universal joint and makes the original universal joint more flexible and freer when working.
Description
Technical field the utility model relates to a kind of automobile constant velocity universal joint.
Its basic structure of the tripod constant-velocity universal joint that uses on the present automobile of background technique (TJ type slippage end) is: telescopic seal closure one end is fixed on to be had in the chamber on three shell aperture with parallel axes cylindricality raceway groove, and the other end is fixed on the transmission shaft.The end that this transmission shaft is positioned at shell connects by involute splines with three axiss of a cylinder, and by the fastening piece positioning and locking.Establish all vertical and their the crossing radial trident axiss of a cylinder that is hexagonal angle of axis on this three axis of a cylinder with drive shaft axis, establish one group of raceway with its parallel axes on every axis of a cylinder, be equipped with a needle roller on each raceway, outside the above-mentioned axis of a cylinder that needle roller is housed, be equipped with the outer spherical lasso.Establish the fastening piece that needle roller is spacing again at every axis of a cylinder free end.The fastening piece that above-mentioned spherical lasso, three axiss of a cylinder, needle roller and needle roller are outer is referred to as three ball pin assemblies.The deficiency of above-mentioned tripod constant-velocity universal joint is: spherical lasso only has phase opposing connection trident axis of a cylinder to rotate and two degrees of freedom of parallel axis of a cylinder slip, makes this universal joint dumb when work.
The summary of the invention the purpose of this utility model is to provide a kind of use tripod constant-velocity universal joint more flexibly, and it mainly is to increase one degree of freedom for spherical lasso again, promptly sets up a sphere lining ring between needle roller in three ball pin assemblies and the spherical lasso.This sphere lining ring is the annulus that outer circumferential face is sphere, and its cylindrical bore diameter is identical with the internal diameter of former outer spherical lasso, and former spherical lasso profile and size constancy, just the cylindrical bore internal diameter enlarges, and cooperates with the outer spherical surface of sphere lining ring.The utility model is when work, the outer spherical surface of outer spherical lasso endoporus and sphere lining ring is slidingly matched, and makes the outer spherical lasso have phase opposing connection trident axis of a cylinder rotational, slide and intersects the three degree of freedom of swinging with the axis of a cylinder axis of trident with respect to trident axis of a cylinder axis.When wheel steering, when three ball pin assemblies reciprocatingly slide along three cylindricality raceway grooves with parallel axes of shell inner cavity with transmission shaft, be that along the circumferential direction swing at the center also with enclosure axis heart line.
The utility model has following advantage compared to existing technology: the utility model has improved the performance of former universal joint, make its when work more nimbly and freely.
Description of drawings Fig. 1 is that the utility model master looks generalized section.Fig. 2 is that Fig. 1 removes the K of seal closure, transmission shaft to view.Fig. 3 is that the master of the utility model sphere lining ring looks schematic representation.Fig. 4 is the A-A view of Fig. 3.
Embodiment is in the schematic representation of tripod constant-velocity universal joint illustrated in figures 1 and 2, telescopic seal closure 1 one ends are fixed on by big band 2 to be had in the chamber on three shell 3 openings with parallel axes cylindricality raceway groove, and the other end is fixed on the transmission shaft 5 by little band 4.The end that this transmission shaft is positioned at shell connects by involute splines with three axiss of a cylinder 6, and with axle with check ring 7 positioning and lockings.Establish on this three axis of a cylinder axis all vertical with drive shaft axis and their intersect the trident axis of a cylinder be hexagonal angle, establish one group of raceway with its parallel axes on every axis of a cylinder, be equipped with a needle roller 8 on each raceway.Outside the above-mentioned axis of a cylinder that is provided with needle roller, be provided with spherical bush circle 9, establish spherical lasso 10 in this sphere lining ring outside.Establish back-up ring and Steel Cable Baffle Ring 11 outside the needle roller again at every axis of a cylinder free end.
