Abstract
The utility model discloses an automobile part, and provides an intermediate shaft structure of automobiles which is simple in structure, fine in crash energy absorption effect, and especially capable of avoiding problem of spline seizure when an intermediate shaft is used. The technical problems that safety accidents can be caused when a spline shaft cannot smoothly slide along a spline tube because of spline seizure of an intermediate shaft when an automobile is driven. The intermediate shaft structure of automobiles comprises a spline tube and a spline shaft, wherein the spline shaft is slidably plugged to one end of the spline tube through a spline, and outer connecting ends of the spline tube and the spline shaft are connected between a steering gear and a steering column. An elastic partition sleeve is sleeved on the spline shaft and between an outer connecting end of the spline shaft and an end surface of the spline tube.
Description
Technical field
The utility model relates to a kind of auto parts and components, relates in particular to a kind of automobile tween drive shaft structure of avoiding tween drive shaft the spline stuck phenomenon in use to occur.
Background technology
Usually adopt the spline sliding block joint between castellated shaft in the existing automobile tween drive shaft structure and the splined tube, automobile castellated shaft in the process of moving slides up and down along splined tube, and when the male splines on the castellated shaft slides to the female splines bottom that cooperates with it on the splined tube, phenomenon in the stuck female splines relief groove in splined tube of castellated shaft often takes place, cause spline stuck thus, castellated shaft can't cause safety misadventure along the smooth and easy slip of splined tube when serious.
Chinese patent discloses a kind of automobile tween drive shaft mounting structure (CN2889775Y), and it has tween drive shaft, bracing frame, bearing, seal ring, back-up ring and differential spring circle; Bracing frame is that the support sleeve by the connecting panel on top and bottom connects to form, connecting panel is installed on the engine cylinder-body, tween drive shaft is through on the support sleeve of bracing frame bottom by bearing, the both sides of bearing are equipped with back-up ring and seal ring, and tween drive shaft is equipped with the differential spring circle at the joint area with right axle assembling.This device is by bracing frame is set on tween drive shaft, and tween drive shaft is fixed on the engine cylinder-body by bracing frame, be convenient to the outputting power that it transmits driving engine thus, part reduces the vibration of tween drive shaft, but in use same the existence is prone to the spline stuck phenomenon, cause castellated shaft to cause technical matterss such as safety misadventure when serious along the smooth and easy slip of splined tube.
Summary of the invention
The utility model mainly provided a kind of simple in structure, collision energy-absorbing is effective, especially can avoid tween drive shaft the automobile tween drive shaft structure of spline stuck phenomenon in use to occur, solve the automobile that exists in the prior art and be prone to tween drive shaft spline stuck phenomenon in the process of moving, cause the castellated shaft can't be, cause the technical matters of safety misadventure etc. when serious along the smooth and easy slip of splined tube.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of automobile tween drive shaft structure, comprise splined tube and pass through the castellated shaft of spline sliding plug at splined tube one end, the outer coupling end of splined tube and castellated shaft is connected between deflector and the Steering gear, be socketed with collapsible dist collar on described castellated shaft, described collapsible dist collar is located between the end face of the outer coupling end of castellated shaft and splined tube.By sheathed collapsible dist collar on the outer coupling end of castellated shaft and the castellated shaft between the splined tube end face; can glide along splined tube at castellated shaft; and the male splines on the castellated shaft is during near the female splines bottom that cooperates with it on the splined tube; the splined tube end face is connected on the collapsible dist collar end face; be clipped in the stressed compressive deformation of collapsible dist collar between the outer coupling end of splined tube end face and castellated shaft; absorb collision energy; the center shaft vibration reduces; the ride comfort height; and the phenomenon in the stuck relief groove on splined tube of castellated shaft can not take place; guarantee castellated shaft along the smooth and easy slip of splined tube, simple in structure, safety is good.
Collapsible dist collar can be plastic jacket, spring of annular arrangement etc., and as preferably, described collapsible dist collar is the nylon jacket that cross-sectional plane is semi-round ring shape, and described collapsible dist collar clip is on the outer ring surface of castellated shaft.When collapsible dist collar is installed, directly snap in castellated shaft, easy accessibility after the collapsible dist collar open end of semi-round ring shape can being aligned castellated shaft; Simple, high, the good springiness of intensity of nylon material processing.
As more preferably, on the annular surface of described collapsible dist collar, be provided with groove, described groove is rectangular distribution on the circumferencial direction of collapsible dist collar.By on the annular surface of collapsible dist collar, groove being set, can save raw MAT'L, save cost, can increase the elasticity of collapsible dist collar simultaneously, be convenient to the installation of collapsible dist collar.
As preferably, the splined surfaces on the described castellated shaft is provided with injection molded layers.By carrying out injection process in splined surfaces, produce when spline fitted is slided inside and outside can preventing and rock and abnormal sound, and reduce vibration, improve to take advantage of and drive traveling comfort.
Therefore, a kind of automobile tween drive shaft structure of the present utility model has following advantage: by cover on castellated shaft collapsible dist collar is set, can be connected on the collapsible dist collar end face at the splined tube end face that makes downslide, thereby avoids tween drive shaft the spline stuck phenomenon to occur; Absorb crash energy behind the collapsible dist collar compressive deformation, reduce vibration, improve ride comfort; The nylon collapsible dist collar of semi-round ring shape, easy for installation, intensity is high, cost is low; By carrying out injection process in splined surfaces, rock the back in can preventing between male splines and cause abnormal sound, improve to take advantage of and drive traveling comfort.
Description of drawings:
Fig. 1 is an assembling scheme drawing of the present utility model;
Fig. 2 is an exploded view of the present utility model.
The specific embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of automobile tween drive shaft structure of the present utility model, comprise splined tube 3 and pass through the castellated shaft 2 of spline sliding plug at splined tube 3 one ends, wherein the outer coupling end of splined tube 3 is connected in the deflector, the outer coupling end of castellated shaft 2 is connected on the Steering gear, as shown in Figure 2, after injection process, form injection molded layers 4 on castellated shaft 2 cooresponding male splines surfaces, suit has been fixed a collapsible dist collar 1 on corresponding to the outer coupling end of castellated shaft 2 and castellated shaft 2 outer ring surfaces between splined tube 3 end faces, collapsible dist collar 1 is the nylon jacket of semi-round ring shape for cross-sectional plane, the opening of nylon jacket inwardly is clamped on the outer ring surface of castellated shaft 2, having the distribution symmetrically on the circumferencial direction of collapsible dist collar 1 of 11, two rectangular grooves 11 of two rectangular grooves on the annular outer surface of collapsible dist collar 1 vertically.
