Abstract
Description
Technical Field
[0001] This utility model relates to the field of segmented electric drive axle vehicle technology, and in particular to a disassembly device for the electric drive axle housing in a new energy electric drive axle system. Background Technology
[0002] Currently, most electric drive axle housings are disassembled using forceful methods, such as hammering the housing to separate the main and auxiliary housing surfaces. This damages the housing's shape and surface anti-rust coating, resulting in overall structural damage. Furthermore, without a disassembly mechanism, pry bars are typically used to apply force at the mating surfaces of the main and auxiliary housings, easily scratching these surfaces and severely affecting the seal. These problems urgently need to be addressed. Utility Model Content
[0003] This utility model discloses a disassembly device for the electric drive axle housing in a new energy electric drive axle system, which aims to solve the technical problems existing in the prior art.
[0004] The present invention adopts the following technical solution: In a first aspect, this utility model provides a disassembly device for an electric drive axle housing in a new energy electric drive axle system. The disassembly device is used to separate the main housing and the sub-housing of the electric drive axle housing. The disassembly device includes a main housing support member, a sub-housing lifting member, a lifting point, and a pry bar. The main housing support member is disposed on the edge of the main housing and protrudes from the edge of the main housing. The sub-housing lifting member is disposed on the edge of the sub-housing and protrudes from the edge of the sub-housing, and is spaced apart from the main housing support member to form an insertion space. The lifting point is located within the insertion space and fixed to the main housing support member, with an insertion gap between it and the main housing support member. The end of the pry bar can be inserted into the insertion gap and can abut against the sub-housing lifting member and the lifting point to pry open and separate the main housing and the sub-housing.
[0005] In the disassembly device for the electric drive axle housing in a new energy electric drive axle system of this utility model, the pry point is a cylindrical structure, and the top surface adjacent to the pry top of the sub-housing housing is a concave surface; the concave surface is used to accommodate the end of the pry bar.
[0006] In the disassembly device for the electric drive axle housing in a new energy electric drive axle system of this utility model, the end of the pry bar has a tapered structure and the end face has an arc-shaped structure, so that when the pry bar pries the sub-housing lifting member and the lifting point, the arc-shaped structure abuts against the concave surface to form a prying support point.
[0007] In the disassembly device for the electric drive axle housing in a new energy electric drive axle system of this utility model, the end of the pry bar has a tapered structure, including a first plane and a second plane; the first plane and the second plane are set at an acute angle, and the first plane is used to abut against the prying point of the sub-housing; the second plane is used to abut against the prying point.
[0008] In the disassembly device for the electric drive axle housing in the new energy electric drive axle system of this utility model, the included angle between the first plane and the second plane is 20-25°.
[0009] In the disassembly device for the electric drive axle housing in the new energy electric drive axle system of this utility model, the pry bar is a bent rod-shaped structure.
[0010] In the disassembly device for the electric drive axle housing in a new energy electric drive axle system of this utility model, the main housing support is integrally formed with the main housing; the secondary housing lifting member is integrally formed with the secondary housing.
[0011] In the disassembly device for the electric drive axle housing in a new energy electric drive axle system of this utility model, the main housing support, the secondary housing lifting member, and the lifting point are arranged in a one-to-one correspondence, and there are multiple of each; the multiple main housing support members are evenly distributed along the edge of the main housing; the multiple secondary housing lifting members and the lifting points are evenly distributed along the edge of the secondary housing.
[0012] In a second aspect, the present invention also provides a new energy electric drive axle system, which includes any of the above-described disassembly devices and an electric drive axle housing.
[0013] The technical solution adopted in this utility model can achieve the following beneficial effects: This utility model mainly provides a disassembly device for the electric drive axle housing in a new energy electric drive axle system. It is based on a main housing support member at the edge of the main housing and a secondary housing lifting member at the edge of the secondary housing. A lifting point is set on the main housing support member. A pry bar is inserted between the secondary housing lifting member and the lifting point, with the end of the pry bar pressing against the lifting point. Lifting the pry bar further separates the main and secondary housings. This avoids damage to the housing surface coating caused by hammering, reducing the cost of painting and finishing the housing, and increasing its service life. It also avoids damage to the mating surfaces of the main and secondary housings, ensuring a good seal, allowing the main and secondary housings to be reused, thus reducing costs. Disassembly using a pry bar is simple, time-saving, and labor-saving, and can be completed by a single person. Attached Figure Description

[0018] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0019] To address the problems existing in the prior art, this application provides a disassembly device for the electric drive axle housing in a new energy electric drive axle system.
[0020] like Figure 1 As shown, a disassembly device for the electric drive axle housing in a new energy electric drive axle system is disclosed. The device is used to separate the main housing A and the secondary housing B of the electric drive axle housing. The disassembly device includes a main housing support 1, a secondary housing lifting member 2, a lifting point 3, and a pry bar 4. The main housing support 1 is located at the edge of the main housing A and protrudes from the edge of the main housing A. The secondary housing lifting member 2 is located at the edge of the secondary housing B and protrudes from the edge of the secondary housing B, and is spaced apart from the main housing support 1 to form an insertion space 5. The lifting point 3 is located within the insertion space 5 and is fixed to the main housing support 1, with an insertion gap between it and the secondary housing lifting member 2. The end of the pry bar 4 can be inserted into the insertion gap and can abut between the secondary housing lifting member 2 and the lifting point 3 to pry open and separate the main housing A and the secondary housing B.
[0021] This utility model discloses a disassembly device for the electric drive axle housing in a new energy electric drive axle system. It is based on a main housing support member 1 at the edge of the main housing A, a secondary housing lifting member 2 at the edge of the secondary housing B, and a lifting point 3 on the main housing support member 1. A pry bar 4 is inserted between the secondary housing lifting member 2 and the lifting point 3, with the end of the pry bar 4 abutting against the lifting point 3. Lifting the pry bar 4 against the secondary housing lifting member 2 and continuing to lift the pry bar 3 further separates the main housing A and the secondary housing B. This avoids damage to the housing surface coating caused by hammering, reduces the cost of painting and finishing the housing, and improves its service life. Furthermore, it avoids damage to the mating surfaces of the main and secondary housings, ensuring a good seal, allowing the main and secondary housings to be reused, thus reducing costs. Disassembly using a pry bar is simple, time-saving, and labor-saving, and can be completed by a single person.
[0022] In some preferred embodiments, the pry point 3 is a cylindrical structure, and the top surface adjacent to the pry top member 2 of the sub-housing is concave; the concave surface is used to accommodate the end of the pry bar 4. Based on this, when prying with the pry bar 4, the end of the pry bar 4 can be held more stably within the concave surface of the top surface of the pry point 3, thereby improving the stability of the disassembly process.
[0023] In some preferred embodiments, the end of the crowbar 4 is tapered and the end face is arc-shaped, so that when the crowbar 4 pries the sub-housing lifting member 2 and the lifting point 3, the arc-shaped structure abuts against the concave surface to form a prying support point; based on this, when the crowbar 4 pries, the arc surface of the end of the crowbar 4 and the arc surface of the concave surface of the lifting point 3 come into contact, which can reduce frictional damage between the two, and the lifting action is more continuous when prying.
[0024] Preferably, the curvature of the concave surface of the top surface of the pry point 3 increases from bottom to top, thereby reducing the probability that the end of the pry bar 4 will detach from the concave surface of the top surface of the pry point 3 during prying, ensuring the stability of the prying operation, and thus improving the splitting efficiency.
[0025] In some preferred embodiments, the end of the pry bar 4 has a tapered structure, such as a tapered end, including a first plane 41 and a second plane 42; the first plane 41 and the second plane 42 are set at an acute angle, and the first plane 41 is used to abut against the sub-housing lifting member 2; the second plane 42 is used to abut against the lifting point 3; based on setting the end of the pry bar 4 to a tapered structure including the first plane 41 and the second plane 42, it is easier to insert it between the sub-housing lifting member 2 and the lifting point 3, and the contact area is increased by having the first plane 41 and the second plane 42 abut against the sub-housing lifting member 2 and the lifting point 3 respectively, thereby improving the stability during prying.
[0026] Preferably, the included angle C between the first plane 41 and the second plane 42 is 20-25°. More preferably, the included angle C is 23.8°.
[0027] In some preferred embodiments, the crowbar 4 is a bent rod-like structure; this makes it easier to operate.
[0028] In some preferred embodiments, the main housing support 1 is integrally formed with the main housing A; the secondary housing tilting member 2 is integrally formed with the secondary housing B.
[0029] In some preferred embodiments, the main shell support 1, the secondary shell lifting member 2, and the lifting point 3 are arranged in a one-to-one correspondence, and there are multiple of each; the multiple main shell support members 1 are evenly distributed along the edge of the main shell A; the multiple secondary shell lifting members 2 and the lifting point 3 are evenly distributed along the edge of the secondary shell B; based on this, it is easier to separate the main and secondary shells by prying at multiple points.
[0030] In some preferred embodiments, the main housing support 1 is provided with a slide groove 11; the slide groove 11 is provided in a direction away from the main housing A and close to the main housing A, and the pry point 3 is slidably disposed in the slide groove 21; thus, when prying, the pry point 3 can be set in different positions in the slide groove 21 for prying, which can increase the distance that the pry bar 4 can pry apart the main housing A and the secondary housing B.
[0031] A new energy electric drive axle system includes the aforementioned disassembly device and electric drive axle housing.
[0032] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
