Embodiment 1

[0020] Such as figure 1 As shown, the snap ring type front drive axle housing assembly includes the front drive axle housing 10 and the snap ring 20, the snap ring 20 is processed with a snap ring groove 21; the front drive axle housing 10 is provided with an inner hole 12, and the front drive axle One end of the shell 10 is provided with a shaft hole 11 coaxial with the inner hole 12 , the inner diameter of the shaft hole 11 is smaller than the outer diameter of the snap ring 20 , and the outer end of the snap ring 20 is pressed into the shaft hole 11 by a press.

[0021] According to the analysis of the function of the snap ring groove 21 and the stress situation, the structure of the split type of the snap ring groove 21 and the front drive axle housing 10 is adopted, and the structure of the snap ring 20 is added, and the snap ring groove 21 is processed on the snap ring 20, and then the The snap ring 20 is press-fitted into the front drive axle housing 10 assembly, and th...

Embodiment 2

[0023] The difference between this embodiment and embodiment 1 is that, as figure 2 As shown, the inner diameter of the inner hole 12 is smaller than the inner diameter of the shaft hole 11, and a plurality of grooves 30 arranged axially along the inner hole 12 are provided on the step surface at the joint between the inner hole 12 and the shaft hole 11. There are four grooves 30 , which are evenly spaced on the same circumference; one end of the snap ring 20 close to the front drive axle case 10 is provided with four engaging parts engaging with the grooves 30 . After the snap ring 20 is pressed into the shaft hole 11 , the engaging portion will be pressed into the groove 30 , so that the connection between the snap ring 20 and the front drive axle case 10 is more firm.

[0024] The side of the groove 30 close to the center of the shaft hole 11 has a plurality of protrusions 31, and the protrusion 31 forms an angle with the side of the inner wall of the groove 30 close to th...

Embodiment 3

[0026] The difference between this embodiment and embodiment 2 is that, as image 3 As shown, the front drive axle case 10 is located on the first slope and is provided with a blind hole 40 perpendicular to the inner hole 12. An insert block 41 is slidably connected to the blind hole 40, and an elastic joint is connected between the insert block 41 and the bottom of the blind hole 40. The piece 42 is slidably connected with a blocking piece blocking the insert block 41 on the first slope, and the block 33 is provided with a card hole 44 for inserting the insert block 41 . When the engaging part extends into the groove 30, the blocking piece can be pushed, so that the rib is removed without blocking the plug 41, and when the blind hole 40 is aligned with the clip hole 44, the plug 41 will be inserted into the clip hole 44 , so as to further increase the connection strength between the snap ring 20 and the front drive axle case 10 .

Abstract

The invention belongs to the technical field of pick-up front driving axle housings, and particularly discloses a clamping-ring-type front driving axle housing assembly. The clamping-ring-type front driving axle housing assembly comprises a front driving axle housing and a clamping ring, and a clamping spring groove is machined in the clamping ring; an inner hole is formed in the front driving axle housing, an axle hole coaxial to the inner hole is formed in one end of the front driving axle housing, and one end of the outer part of the clamping ring is pressed into the axle hole through pressure. Compared with the prior art, the front driving axle housing assembly is low in machining difficulty, low in production cost and wide in applicability.

Description

technical field [0001] The invention belongs to the technical field of pickup truck drive axle housings, and specifically discloses a snap ring type front drive axle housing assembly. Background technique [0002] During the operation of the vehicle, the engine generates power, which is transmitted to the drive axle through the clutch, transmission and transmission shaft. The driving force is driven by the main reducer of the drive axle by reducing the speed and increasing the torque, changing the direction of power transmission, and realizing the differential movement of the vehicle by the differential. Performance, the output power of the main reducer is distributed to the left and right half shafts by the half shaft gears, and the half shafts drive the wheels to rotate to make the car move. Generally speaking, the final drive, differential and half shaft devices are all installed on the drive axle housing. The drive axle housing not only protects the above-mentioned trans...
