Detailed description of the invention
Core of the present utility model is to provide a kind of truck drive shaft and differential mechanism attachment structure,
Can be good at the Leakage solving power transmission shaft with differential mechanism junction.
Another core of the present utility model is to provide one to have above-mentioned truck drive shaft and differential
The automobile of device attachment structure.
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with
The utility model is described in further detail for the drawings and specific embodiments.
Truck drive shaft disclosed in this utility model embodiment and differential mechanism attachment structure, including
Power transmission shaft and coupled differential mechanism, power transmission shaft is provided with for the one end being connected with differential mechanism
First ring flange 11, differential mechanism is provided with the second flange matched with the first ring flange 11
Dish, the first ring flange and the second ring flange are close to connect by bolt lock, therefore compare traditional flower
Bonded form, uses the contact area of ring flange type of attachment to increase, and sealing effectiveness strengthens,
Not easily lead to coordinate untight problem to occur, thus the most just solve spline in prior art
Connect produced Leakage, enhance torque-transfer capability simultaneously.And due to ring flange
Connect and offer spline tooth without the end at power transmission shaft, therefore compare spline type of attachment, flange
Dish connection increases clearance space 19, here, it is to be understood that clearance space 19 refers to
Space between first ring flange 11 and internal spherical cage housing 14.The increase in space not only contributes to
The dismounting of power transmission shaft, and effectively prevent the local interference problem in arrangement.When
So, owing to the arrangement space needed for the car load of different automobile types is different, therefore can be by adjusting first
The position of ring flange 11 or internal spherical cage adjusts clearance space 19, to adapt to the whole of different automobile types
Local interference problem in the layout of car space.
It should be noted that for the weight alleviating car load further, this utility model embodiment
All offer on the first disclosed ring flange 11 and the second ring flange multiple be correspondingly arranged subtract
Weight groove 111, it is to be understood that lightening recesses open the most, be more conducive to alleviating car load
Weight, but in order to reduce the complexity of ring flange processing technique, ensure ring flange simultaneously
Bonding strength, lightening recesses disclosed in this utility model embodiment is preferably 3, and this was both
Be conducive to alleviating the weight of car load, the complexity of processing technique can be reduced again, the most also ensure
The bonding strength of ring flange.
Power transmission shaft is passed to owing to differential mechanism need to be delivered to the power of variator electromotor, so
Power transmission shaft need to keep consistent with the rotation direction of differential mechanism outfan and rotating speed, in order to ensure to rotate
Balance, the lightening recesses 111 on any one ring flange is the circumference along its place ring flange
It is evenly arranged.
Owing to the first ring flange 11 and the second ring flange need to carry out being assembled to form entirety, could be by difference
The power of speed device outfan is delivered to power transmission shaft, so need to be by the first ring flange 11 and the second flange
Dish is locked, and therefore should arrange pilot hole 113 on the first ring flange 11 and the second ring flange,
Pilot hole 113 is arranged in the projection 112 between adjacent two lightening recesses 111, is simultaneously
Make ring flange be more prone to when assembling, coordinate more tight, need at the first ring flange 11
Center detent 114 is set, the center of the second ring flange arrange and groove
Adaptive positioning convex, it is of course also possible to arrange location in the center of the first ring flange 11
Projection, the center of the second ring flange arranges the detent 114 adaptive with positioning convex.
It is to be understood that the first ring flange 11 and the second ring flange are for being arranged concentrically, detent
114 is concentric fit with positioning convex, is arranged such, so that the joining of whole attachment structure
Close more tight, and be more beneficial for the first ring flange 11 and assembling of the second ring flange.
It is true that the quantity of pilot hole 113 can be multiple, quantity is the most, the first ring flange
11 will be the most firm with the connection of the second ring flange, and therefore torque-transfer capability will be higher, but
It is on the one hand to increase the complexity of ring flange processing technique, on the other hand also can lose time
And production cost.As preferably, any one projection 112 is provided with two pilot holes 113,
Two pilot holes are set in each projection and are enough to ensure that the first ring flange 11 and the second ring flange dress
The steadiness joined, meanwhile, also can reduce the process complexity in the ring flange course of processing, and subtract
Few time and the waste of production cost.
Refer to accompanying drawing 1, the internal spherical cage housing 12 of power transmission shaft 1 is additionally provided with and facilitates support machine
The gathering sill 14 that structure 13 is inserted in, gathering sill 14 is arranged at internal spherical cage housing 12 away from the first method
On the end face of one end of blue dish 11.The setting of gathering sill 14, can be inserted at supporting mechanism 13
During power transmission shaft, it is to avoid supporting mechanism 13 and showing that internal spherical cage housing collides with occur owing to space is little
As, the guiding that therefore assembling being set to supporting mechanism 13 of gathering sill 14 is provided convenience is made
With.
In order to make internal spherical cage sheath 15 tightr, at internal spherical cage sheath 15 with coordinating of power transmission shaft
One end end face away from the first ring flange 11 is provided with protruding the dashing forward of centrage towards power transmission shaft
Go out part 16, the periphery of power transmission shaft be provided with and the groove 17 of ledge 16 adaptation,
Hoop 18 is set on internal spherical cage sheath 15, by internal spherical cage sheath 15 banding in transmission simultaneously
On axle, it is arranged such, so that internal spherical cage sheath 15 is more firm with the connection of power transmission shaft,
Avoid cause owing to the connection of internal spherical cage sheath and transmission is insecure in power transmission process to move
The appearance of the problems such as power interruption.
Also disclosing a kind of automobile in this utility model, this automobile includes truck drive shaft and differential
Device attachment structure, and this power transmission shaft and differential mechanism attachment structure be in above-mentioned any one embodiment
Disclosed power transmission shaft and differential mechanism attachment structure.
It is connected with differential mechanism owing to this automobile have employed power transmission shaft disclosed in above-described embodiment
