Abstract
Description
Technical Field
[0001] This utility model relates to the field of gearbox housing disassembly technology, and in particular to a tooling for disassembling a new energy gearbox housing. Background Technology
[0002] The reducer (gearbox) of a new energy vehicle is a core component of the electric drive system. It converts the high-speed rotation of the motor into a low-speed, high-torque output suitable for the wheels, optimizing traction and acceleration performance. The motor is most efficient when it operates in the high-efficiency range (such as medium to high speed). By adjusting the transmission ratio, the reducer allows the motor to operate in the high-efficiency range as much as possible, improving overall energy efficiency. When turning or driving on uneven roads, the reducer (such as a differential) ensures that the left and right drive wheels rotate at different speeds, avoiding tire slippage or excessive wear and improving driving stability. By limiting torque output, the reducer can protect the motor and transmission system from overload impacts and extend their service life.
[0003] In the disassembly of the front and rear housings of a reducer, manual disassembly is generally used. A hammer and a smooth rod are used to repeatedly strike multiple surfaces of the front housing to separate it from the rear housing. However, this striking process can cause deformation and impact marks on the front housing, rendering it unusable and resulting in wear and tear. Furthermore, manual hammering is time-consuming and labor-intensive, increasing costs and posing safety risks. Therefore, this invention proposes a new energy reducer housing disassembly tooling to address the shortcomings of existing technologies. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to provide a disassembly fixture for a new energy gearbox housing. The disassembly fixture can be connected to the rear housing of the gearbox via a first and a second perforated handle bolt. The three sets of separation screws can apply force to the front housing by rotation, thereby removing the front housing from the rear housing and easily separating the front and rear housings, thus reducing operational hazards.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A disassembly fixture for a new energy vehicle gearbox housing includes a housing separation base plate, a separation screw, a handle rod, a first Phillips-shaped handle bolt, and a second Phillips-shaped handle bolt. The housing separation base plate has three sets of through holes, each with a threaded hole seat at its bottom. The separation screw passes through each through hole and is threaded to the threaded hole seat. A rubber-coated bearing is located at the bottom of the separation screw, and a handle rod is located at its upper end. The housing separation base plate has three sets of first through holes. A first top block is located at the bottom of the housing separation base plate at each of the three sets of first through holes. The first top block has a first connecting screw hole concentrically aligned with the first through hole. The first Phillips-shaped handle bolt passes through the first through hole and is threaded into the first connecting screw hole. A second top block is located at the bottom of the housing separation base plate at the second through hole. The second top block has a second connecting screw hole concentrically aligned with the second through hole. The second Phillips-shaped handle bolt passes through the second through hole and is threaded into the second connecting screw hole.
[0007] A further improvement is that the threaded hole seat is provided with a first mounting bolt, and the threaded hole seat can be detachably installed from the housing base plate through the first mounting bolt.
[0008] A further improvement is that handles are provided on both sides of the top of the housing separation base plate, and the handles are detachably installed to the housing separation base plate by means of second assembly bolts.
[0009] A further improvement is that: both the first and second top blocks are provided with a third mounting bolt that can be detachably installed from the housing base plate, and the height of the first top block is less than the height of the second top block.
[0010] A further improvement is that the three sets of separating screws are arranged in a triangular array on the housing separating base plate, and the three sets of the first plum blossom handle bolts are arranged in a triangular array on the housing separating base plate.
[0011] A further improvement is that the housing separation base plate is provided with weight reduction holes, and there are two weight reduction holes, the positions of which are adapted to the positions of the protrusions on the rear housing of the gearbox.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a disassembly fixture consisting of a housing separation base plate, a separation screw, a handle rod, a first pentagonal handle bolt, and a second pentagonal handle bolt. The entire disassembly fixture can be connected to the rear housing of the reducer via the first pentagonal handle bolt and the second pentagonal handle bolt. The three sets of separation screws can apply force to the front housing by rotation, thereby removing the front housing from the rear housing, thus easily separating the front housing from the rear housing and reducing operational hazards.
[0013] The present invention provides a rubber-coated bearing at the bottom of the separating screw to prevent the separating screw from directly contacting the front shell and causing rotational friction on the front shell, thereby effectively protecting the quality of the front shell.
