In order to overcome the shortcomings of that background technology, the utility model provide rear axle monoblock type chain drive constant velocity universal joint drive spindle
Assembly, the engine for mainly solving present automobile are to drive universal joint drive spindle assembly to rotate by transmission shaft mostly, structure
More complicated problem.
Technical solution used by the utility model is：
Rear axle monoblock type chain drive constant velocity universal joint drive spindle assembly, including mounting bracket, the first cage assembly and the second ball
Cage assembly, the first cage assembly include the first external ball cage and the first internal spherical cage being correspondingly arranged, and the internal spherical cage includes the
One shell, the second cage assembly include the second external ball cage and the second internal spherical cage being correspondingly arranged, the second internal spherical cage packet
Second shell is included, the first shell is connect with the second shell, further includes mounting base, the first shell and described second
Housing parts are set in the mounting base and are equipped between the mounting base inner wall bearing, and the first shell, which is equipped with, to be synchronized
The sprocket wheel of rotation.
The utility model has the beneficial effects that：The utility model provides rear axle monoblock type chain drive constant velocity universal joint drive spindle
Assembly, motor can be rotated by chain-driving sprocket wheel, and then drive universal joint drive spindle rotation, simple in structure, using effect
It is good.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model one embodiment.
Fig. 2 is the enlarged diagram at A in Fig. 1.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：As shown, rear axle monoblock type chain drive constant speed ten thousand
To section drive shaft assembly, including mounting bracket 1, the first cage assembly 2 and the second cage assembly 3, it is characterised in that：First ball
Cage assembly includes the first external ball cage 21 and the first internal spherical cage 22 being correspondingly arranged, and the internal spherical cage includes first shell 221, described
Second cage assembly includes the second external ball cage 31 and the second internal spherical cage 32 being correspondingly arranged, and second internal spherical cage includes second shell
Body 321, the first shell are connect with the second shell, further include mounting base 5, the first shell and the second shell
Part is set in the mounting base and is equipped between the mounting base inner wall bearing 6, and the first shell 221, which is equipped with, to be synchronized
The sprocket wheel 7 of rotation.Automobile engine rotation is rotated by chain-driving sprocket wheel, and then drives drive shaft assembly rotation, and first
Cage assembly includes the first external ball cage and the first internal spherical cage, and the first external ball cage and the second internal spherical cage include jackshaft, inner race
With retainer and spin, it is the prior art, is no longer described in detail, this constant velocity universal joint drive spindle assembly replaces passing using sprocket wheel transmission
The axis of system is driven, and simple in structure, using effect is good.
In the present invention, as shown, the first shell, which is equipped with, is correspondingly provided with bulge loop 223 and baffle ring 224, institute
It states sprocket wheel back and compresses cooperation with the bulge loop, the sprocket wheel front end face compresses cooperation with the baffle ring.The sprocket wheel inner wall with
The first shell outer wall key connection.It is energy-efficient using spline drived.
In the present invention, as shown, the first shell and second shell welding.It assembles more convenient.
In the present invention, as shown, the second shell is equipped with the brake disc 322 of key connection.In monoblock type
Brake mounting disc is devised on constant velocity universal joint drive spindle assembly.It, can be from nearest power output end into action edge in braking
Control, to effectively reduce braking time.
In the present invention, as shown, being equipped in first between first external ball cage, 21 and first internal spherical cage 22
Countershaft 23 further includes dirt-proof boot 8, and 8 one end of the dirt-proof boot is connect by clip with 23 outer wall of the first jackshaft, the other end
It is connect with the circumferential wall of the first shell 221 by clip.It can prevent dust from entering, increase service life.
Embodiment is not construed as limitations of the present invention, but changes made by any spirit based on the utility model
Into should all be within the protection scope of the utility model.
