Abstract
The invention discloses a spline sealing structure with reduced axial size and belongs to the technical field of automobile space arrangement. The spline sealing structure comprises a spline located at an engine speed changer connection spline shaft which connects an engine and a speed changer. The projection of the spline and the projection of a box body of a gearbox are at least partially overlapped on the engine speed changer connection spline shaft. On the basis that the bearing capacity and the sealing capacity of the spline are not changed, the size of the connection whole of the gearbox, a clutch and an engine is effectively reduced, and therefore the size of the whole machine is reduced and automobile body space is greatly optimized.
Description
Technical field
The invention belongs to motor space and arrange field, relate to a kind of spline hermetically-sealed construction.
Background technology
In prior art, the connection diagram of typical driving engine and change-speed box case as shown in Figure 1.Wherein, wet-type dual-clutch change speed gear box 1 drives hydraulic oil to control combination and the disconnection of double-clutch by oil pump, and clutch assembly is soaked in hydraulic oil, thereby reaches the object of cooled clutch 2.Driving engine 3 by spline joint by transmission of power to double-clutch drive hub, thereby power is inputted to change speed gear box 1.
In order to guarantee the lubrication effect of change speed gear box 1, guarantee again enough transmission of powers simultaneously, need to the hydraulic oil in power-transfer clutch 2 and spline be separated completely by the oil sealing on gear oil cap, to reach the object of sealing and transmission of power simultaneously; Current vehicle is arranged tendency compact design, for the maximization of implementation space, need control the outer profile size of change speed gear box 1.For change speed gear box 1, mainly at the research and development initial stage, from aspect drive line layout, be optimized at present, thereby reach the object that reduces whole box sizes; But be confined to the structural arrangement of transmission system, cannot realize the maximization of dimension reduction.
Summary of the invention
The object of the present invention is to provide a kind of spline hermetically-sealed construction that can optimize vehicle space.
In order to achieve the above object, solution of the present invention is:
Reduce a spline hermetically-sealed construction for axial dimension, comprise that being positioned at engine speed changer connects the spline on castellated shaft, it is the castellated shaft of connecting engine and change-speed box that described engine speed changer connects castellated shaft; Wherein, the casing of described spline and described change speed gear box described engine speed changer be connected on castellated shaft to be projected to small part overlapping.
Described spline is connected the axial length on castellated shaft with the oil sealing that the length of the casing axial overlap part of described change speed gear box is less than or equal on described change speed gear box at described engine speed changer.
Described spline hermetically-sealed construction also comprises that being positioned at described engine speed changer connects the sealing member on castellated shaft; Between described sealing member, described spline and described engine speed changer connection spline, form counterbore.
Described sealing member is hollow cylindrical.
Owing to adopting such scheme, the invention has the beneficial effects as follows: the spline hermetically-sealed construction that the present invention reduces axial dimension is not changing on the basis of spline load-carrying capacity and seal ability, effectively reduced the size of change speed gear box, power-transfer clutch and driving engine connecting overall, and then reduced complete machine size, greatly optimized vehicle body space.

The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
In order to optimize vehicle space, the present invention proposes a kind of spline hermetically-sealed construction that reduces axial dimension.
Be illustrated in figure 2 engine speed changer in prior art and connect the structural representation that castellated shaft is connected with change speed gear box, wherein engine speed changer connection castellated shaft is the castellated shaft of connecting engine and change-speed box.In Fig. 2,701 is the first gear box, and 501 for connecting the first castellated shaft of change speed gear box and driving engine, and the first spline 601 is positioned on the side of the first castellated shaft 501, and length is X; The first oil sealing 401 is distributed in the both sides of the first castellated shaft symmetrically.Wherein, the end, one end (being exposed junction) that the first castellated shaft 501 stretches out change speed gear box is L to the axial distance of the first gear box 701, the first spline 601 stretches out one end of change speed gear box and the first gear box 701 between the projection of the first castellated shaft in the first castellated shaft 501, and the integral body of the first castellated shaft 601 is positioned on the exposed parts of the first castellated shaft 501.
The present invention is considering on the basis of drive line layout scheme, from design of part aspect, further optimize change speed gear box axial dimension, thereby maximize, realize body structure compact Layout, be illustrated in figure 3 the structural representation that spline hermetically-sealed construction that the present invention reduces axial dimension is connected with change speed gear box, Fig. 4 is the structural representation of the spline hermetically-sealed construction of this reduction axial dimension; Wherein, 702 is the second gear box, and 502 for connecting the second castellated shaft of change speed gear box and driving engine.
This spline hermetically-sealed construction comprises the second spline 602 and the sealing cylinder 8 being positioned on driving engine and power-transfer clutch attaching parts the second castellated shaft 502 sides.Wherein, the second spline 602 and the axis projection of the second gear box 702 on the second castellated shaft 502 partially overlap, therefore in the situation that the length of the second spline 602 is constant with respect to the length of the first spline 601, the length that the second castellated shaft 502 of the present invention is stretched exposed parts can be less than the length of the first castellated shaft 501 exposed parts, thus the space between greatly having saved from change speed gear box to driving engine.
Spline hermetically-sealed construction of the present invention, when implementing, can be about to spline and O-ring column sleeve is processed separately in part manufacture, is then coated with leakproofing material and is pressed into one; Also can adopt the method for finish forge that spline and O-ring cylinder are made to one, then O-ring cylinder is carried out to machine up.
In summary, the present invention, with respect to prior art, can make spline expose end axial integral translation distance X, thereby the former length L exposing is reduced to (L-X), and the size of complete machine also reduces thereupon; Meanwhile, the spline in the second castellated shaft 502 unexposed portions can make spline effectively in conjunction with length, not change, thereby the load-carrying capacity of spline does not change; In addition,, due to the existence of empty set at the sealing cylinder 8 of spline outside, the seal ability of castellated shaft can not change yet.Therefore, the present invention is not changing on the basis of spline load-carrying capacity and seal ability, has effectively reduced the size of change speed gear box, power-transfer clutch and driving engine connecting overall, and then has reduced complete machine size, has greatly optimized vehicle body space.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiment, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not departing from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
