Second live axle of the present invention, it possesses: the constant velocity joint outside the side of a ship; Constant velocity joint inside the side of a ship; And one end be linked to constant velocity joint outside the side of a ship and the other end is linked to the transmission of torque axle of the constant velocity joint inside the side of a ship,
Each constant velocity joint is the sliding-type constant velocity joint of the torque transmission member possessing lateral joint parts, inner contact parts and carry out transmitting torque between lateral joint parts and inner contact parts,
Wherein,
The inner contact parts of each constant velocity joint have the inner ring constituting portion being accommodated in described lateral joint parts, the axle constituting portion forming described transmission of torque axle is arranged continuously with Construction integration and this inner ring constituting portion, and the axle constituting portion of the constant velocity joint inside the axle constituting portion of the constant velocity joint outside the side of a ship and the side of a ship engages as straight line shape through jack shaft.
But, when the aperture surface embedded axle of inner contact parts, in order to ensure the intensity of inner contact parts, need to make the wall thickness of inner contact parts thicker, thus in its outside dimension of reduction, there is gauge in the lateral joint parts of collecting inner contact parts.As the present invention, if make inner ring constituting portion and transmission of torque axle be integrated structure, then do not need at inner ring aperture surface embedded axle.Therefore, when not making track groove shoal, the outside dimension of inner ring constituting portion can being reduced, be accompanied by this, when not making track groove shoal, the outside dimension of lateral joint parts can be reduced.
In addition, the end outside the side of a ship of the transmission of torque axle of this live axle is linked to the constant velocity joint outside the side of a ship, and the end inside the side of a ship of transmission of torque axle is linked to the constant velocity joint inside the side of a ship.Therefore, if make inner ring constituting portion and transmission of torque axle be integrated structure, then inner ring constituting portion is set at the two end part of transmission of torque axle.Therefore, the technology of structure is integrated according to inner ring constituting portion and transmission of torque axle, then when each constant velocity joint assembling boots, need to make the internal diameter size of the axle assembly department (minor diameter part) of boots to be can by the such size of inner ring constituting portion.But if the internal diameter size of the axle assembly department (minor diameter part) of boots is made such size, then the internal diameter size of this axle assembly department (minor diameter part) becomes the outside dimension of the boots assembly department being greater than axle.When keeping this state constant, when the axle assembly department of boots is assemblied in the boots assembly department of axle, adhesion is poor, cannot play sealability.Therefore, the boots assembly department making axle is needed to be the large footpath corresponding with the internal diameter size of the minor diameter part of boots.So, if realize the maximization of the boots assembly department of axle, then cause axle to become heavy, and need for realizing the parts maximized, cause number of spare parts increase and assembling number in man-hour to increase.

In addition, the boots department of assembly 86,136 with boots assembling groove 85,135 is formed in axle constituting portion 73,123.Further, at minor diameter part 80b, 130b of these outer boots 80,130 in boots department of assembly 86,136, the chimeric fastening boots band 88,138 of band telescoping groove 87,137 of outer circumferential face of minor diameter part 80b, 130b of boots 80,130 is being arranged at.Thus, minor diameter part 80b, 130b of boots 80,130 are installed in the boots department of assembly 86,136 of axle constituting portion 73,123.
When the constant velocity joint 41 outside the relatively side of a ship and the constant velocity joint 42 inside the side of a ship, only the outer shape of lateral joint parts 53,103 is different, and the shape at other positions is identical.Therefore, in the present invention, only the outer shape of lateral joint parts 53,103 is different, and other positions are common design.
Now, the axle constituting portion 73 of constant velocity joint 41 outside the side of a ship engages as docking shape with the axle constituting portion 123 of the constant velocity joint 42 inside the side of a ship by the constant velocity joint 41 outside the side of a ship and the constant velocity joint 42 inside the side of a ship.That is, by the end face 73a of engages axle the constituting portion 73 and end face 123a of axle constituting portion 123, thus transmission of torque axle 43 is formed.
Engage (metal bond method) to have riveted joint, be threadedly engaged or the mechanically engaging method such as press-in, the metallurgical weld methods such as fusion weld, crimping, soldering, the joint of axle constituting portion 73 and axle constituting portion 123 can adopt these various bonding methods.At this, fusion weld uses welding consumables to be made it to heat by welding consumables to melt with the mother metal that will engage together with, thus by method that mother metal and mother metal link up.Crimping be give some heats or completely not give heat and with the method for press-in connection.Soldering only makes solder (weldering and material) fusing, and the method making it flow into the border in conjunction with metal to engage.
When carrying out fusion weld, such as preferred laser bonding.So-called laser bonding refers to laser to be thermal source, mainly irradiates to metal under the state of light harvesting, metal partial melting is solidified thus carries out the method that engages.Laser bonding has at a high speed can fuse into welding deeply, welding heat affected considerably less, and the advantage such as welding deformation is few.

In addition, also can be different from described mechanically engaging method or metallurgical weld method, be the bonding using Bond.As Bond, the various Bond being suitable for this metal can be adopted according to the metal used.
Below, the assembling method of this live axle is described.First, the constant velocity joint 41 outside the side of a ship and the constant velocity joint 42 inside the side of a ship is assembled respectively.That is, assemble the constant velocity joint 41 outside the side of a ship at lateral joint parts 53, the constant velocity joint 41 wherein outside the side of a ship contains and is connected with Construction integration the inner ring constituting portion 72 arranged with axle constituting portion 73.In addition, assemble the constant velocity joint 42 inside the side of a ship at lateral joint parts 103, the constant velocity joint 42 wherein inside the side of a ship contains and is connected with Construction integration the inner ring constituting portion 122 arranged with axle constituting portion 123.
Then, boots 80,130 are assembled at each constant velocity joint 41,42.Now, boots 80,130 are inserted with the end of inner ring constituting portion opposite side from each axle constituting portion 73,123, the boots department of assembly 82,132 of the mouth 60,110 of lateral joint parts 53,103 will be embedded in outside large-diameter portion 80a, 130a of each boots 80,130, and the boots department of assembly 86,136 of axle constituting portion 73,123 will be embedded in outside minor diameter part 80b, 130b of each boots 80,130.Afterwards, relative to large-diameter portion 80a, 130a and the fastening boots band 84,134,88,138 of minor diameter part 80b, 130b of each boots 80,130.Thus, the constant velocity joint 41,42 being equipped with boots 80,130 can be formed.
Then, form the state of end face 73a, 123a docking of the axle constituting portion 73,123 of this constant velocity joint 41,42, engage this end face 73a, 123a with aforesaid various joint method.Thus, live axle is assembled.
But the constant velocity joint 41 outside the side of a ship of the live axle of so assembling and the constant velocity joint 42 inside the side of a ship are double offset type constant velocity joints.Therefore, the amount of sliding axially as live axle can be shared using the constant velocity joint 41 outside the side of a ship and the constant velocity joint 42 inside the side of a ship.That is, when setting necessary slippage as L as live axle, by sharing slippage by the constant velocity joint 41 outside the side of a ship and the constant velocity joint 42 inside the side of a ship, thus can be set to and can respectively slide with 2/L.
In the present invention, because inner ring constituting portion 72,122 and transmission of torque axle 73,123 are integrated structure, so need not at inner ring aperture surface embedded axle.Therefore, just can reducing the outside dimension of inner ring constituting portion 72,122 when not making track groove shoal, being accompanied by this, when not making track groove shoal, the outside dimension of lateral joint parts 53,103 can be reduced.That is, when guaranteeing that the durability same with existing this live axle or torque load capacity etc. are constant, the outside dimension of lateral joint parts 53,103 can be reduced.Thus, lightweight and compactness can be reached.
And in this live axle, when each constant velocity joint assembling boots, minor diameter part 80b, 130b of boots 80,130 need not pass through inner ring constituting portion.Namely, the internal diameter size of minor diameter part 80b, 130b of boots 80,130 need not be made to be can by the such major diameter of inner ring constituting portion, therefore, in axle constituting portion, the large-diameter portion that the internal diameter size of minor diameter part 80b, the 130b becoming large footpath with this is corresponding need not be set.Therefore, the large footpath of boots assembly department of axle constituting portion 73,123 need not be made, the re-quantization of axle can not be caused, there is no need for the parts realizing maximizing, the increase of number of spare parts or assembling number in man-hour can not be caused.
Constant velocity joint 41 outside the side of a ship and the constant velocity joint 42 inside the side of a ship due to the different common design product of the outer shape that is only lateral joint parts 53,103, so the more than half common of the constituent part used can be realized.Therefore, it is possible to realize equipment common for the manufacture of these parts, cost degradation can be realized.And, the raising of assembling performance can also be realized.
The amount of sliding axially as live axle can be shared by the constant velocity joint 41 outside the side of a ship and the constant velocity joint 42 inside the side of a ship.Therefore, the depth shallower in outer shroud (cup) portion of the lateral joint parts 53,103 of each constant velocity joint 41,42 can be made.Thus, the lightweight of lateral joint parts can be realized.In addition, in said embodiment, to outer diameter face and the process of track groove surface enforcement hermo-hardening of inner ring constituting portion 72,122.If so implement hermo-hardening process, reduce the wearing and tearing that each part produces because of slip each other, the function as constant velocity joint can be played for a long time.
More be abutted against in a structure of opening side configuration than the sphere centre Ob of aperture surface 58b, 108b of retainer 58,108 at the outer diameter face 58a of retainer 58,108, the sphere centre Oa of 108a, lateral joint parts 53 can be made such as to reduce about 3mm ~ 8mm relative to the degree of depth (the outer shroud degree of depth) of the slippage of inner body S (part be made up of inner ring constituting portion 72,122 and ball 57,107 and retainer 58,108 etc.).Therefore, the lightweight of joint can be realized.
According to double offset type constant velocity joint, the constant velocity joint 41 outside the side of a ship and the constant velocity joint 42 inside the side of a ship can be made to be most suitable for not needing rear drive shaft or the transmission shaft at big-movement angle.
