Description

TECHNICAL FIELD

[0001] The utility model relates to differential hoist technical field of gearbox, especially to a differential hoist of gearbox. BACKGROUND

[0002] The differential of gearbox is a key component in the automobile transmission system. It mainly plays the role of coordinating the speed difference of left and right wheels when the automobile turns or drives on different road surfaces. When the automobile turns, the outside wheel needs to rotate a faster distance than the inside wheel, and the differential can allow the existence of this speed difference, so that the two side wheels can rotate at different speeds, thereby ensuring the stability and maneuverability of the vehicle turning. In four-wheel drive vehicles, the differential can also distribute power between different drive shafts to adapt to complex road conditions and driving needs. At the same time, the normal work of the differential has an important influence on the power transmission efficiency of the vehicle, the uniformity of tire wear, etc.

[0003] The differential of gearbox is an indispensable part of the automobile transmission system. The differential of gearbox can improve vehicle maneuverability, reduce tire wear, improve vehicle passability and improve vehicle stability, but during the installation and maintenance of the differential of gearbox, a professional hoist is usually needed to lift and move it. However, during the lifting process, the hoist and the surface of the differential of gearbox may not be precisely fitted, resulting in shaking during the lifting process, which affects the stability of the overall lifting process. SUMMARY

By opening multiple clamping grooves on the outer surface of the lifting tool disc, the layered clamping grooves can be precisely clamped with the outer wall of the gearbox differential, thereby avoiding loosening during lifting and increasing the stability of the entire lifting process. The outer wall of the lifting tool disc is provided with a through hole groove, the through hole groove is slidably connected with a guide rod, and the guide rod is fixedly connected with a lifting tool pull ring. The guide rod can precisely connect the lifting tool pull ring with the lifting tool disc, thereby avoiding misalignment during connection.

[0008] As a further improvement of the above scheme, the outer wall of the lifting tool disc is provided with two through hole grooves, and the two through hole grooves are symmetrically distributed around the lifting tool disc.

[0009] Through the technical scheme, the outer wall of the lifting tool disc is provided with two through hole grooves, and the two through hole grooves are symmetrically distributed around the lifting tool disc. The installation positions of the guide rod and the lifting tool pull ring can be determined through the through hole grooves, so that the lifting tool pull ring can be precisely fixed at the center point of the lifting tool disc, thereby making the lifting tool force more uniform, and uniform force distribution helps to prevent local force of the lifting tool from being too large and damaging, thereby ensuring the safe operation of the lifting operation.

[0010] As a further improvement of the above scheme, the top end of the guide rod is fixedly connected with a lifting tool pull ring, and the end of the guide rod is provided with a threaded hole.

[0011] Through the technical scheme, the guide rod is fixedly connected with the lifting tool pull ring, and the end of the guide rod is provided with a threaded hole. The threaded hole can be matched with a locking nut, thereby stably connecting the lifting tool pull ring with the lifting tool disc.

[0012] As a further improvement of the above scheme, the outer wall of the threaded hole is threadedly connected with a locking nut.

[0013] Through the technical scheme, the threaded hole is threadedly connected with the locking nut. The size of the threaded hole and the inner diameter of the locking nut are matched with each other, thereby locking the threaded hole through the locking nut, and thereby ensuring the stability of the connection between the lifting tool pull ring and the lifting tool disc.

[0014] As a further improvement of the above scheme, the guide rod extends through the lifting tool disc and the through hole groove to the inside of the locking nut.

[0015] Through the technical scheme, the guide rod extends through the lifting tool disc and the through hole groove to the inside of the locking nut. The guide rod can provide guidance when the locking nut and the threaded hole are connected, thereby ensuring that the locking nut can precisely lock the threaded hole.

[0016] As a further improvement of the above scheme, the number of the locking nuts is set to two, and the two locking nuts are symmetrically distributed left and right around the sling pull ring.

[0017] Through the above technical scheme, the number of the locking nuts is two, and the two locking nuts can lock the threaded openings at the two ends of the sling pull ring respectively, so that the firmness of the connection between the sling pull ring and the sling disc can be ensured, and loosening and falling off during hoisting can be avoided.
