[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0027] like Figure 1-Figure 3 As shown, in one embodiment, a powertrain disassembly and assembly tool is used for carrying components when disassembling and assembling a vehicle powertrain. When in use, the tool is placed under the powertrain for use.

[0028] Its specific structure includes:

[0029] The base 1 is a square plate structure. In order to improve its load-bearing strength, in some preferred embodiments, a plurality of reinforced metal square tubes can be fixed below the base 1.

[0030] The base 1 is provided with mounting holes 5 in an array, and the mounting holes 5 can be threaded holes. The hydraulic push rods 2 are placed at the corresponding mounting holes 5 as required, and the hydraulic push rods 2 can be fixed by bolts 8. Similarly, multiple groups of hydraulic push rods 2 can be provided as required. When supporting the power assembly, the independent hydraulic push rods 2 can be adjusted to different heights, so as to adapt to the shape of the bottom of the power assembly, maintain the stability of the power assembly during disassembly and assembly, effectively improve the disassembly and assembly efficiency, and reduce the risk of safety accidents.

[0031] The lifting and lowering of the hydraulic push rod 2 is achieved by connecting the master pump 3 to the hydraulic push rod 2 through a hydraulic pipeline 4, and supplying or stopping oil supply to the hydraulic push rod 2 through the master pump 3. As for the connection method of the hydraulic pipeline 4 between the hydraulic push rods 2, as a relatively mature existing technology, no further description is given here.

[0032] Furthermore, a plurality of legs 11 are fixed below the base 1, and rollers are provided below the legs 11, which makes it easier to push the tool to where it is needed. A locking brake can be provided on the outside of the roller, and when it is necessary to stop, a stable stop can be achieved by stepping on the locking brake.

[0033] In some preferred embodiments, a soft buffer head 6 is provided at the top of the hydraulic jack 2, and the soft buffer head 6 can be made of rubber. The hydraulic jack 2 is generally made of metal, and the hard friction damage of the hydraulic jack 2 to the powertrain can be reduced by providing the soft buffer head 6. Furthermore, at the center of the soft buffer is a cavity structure 7, in which a bolt 8 is fixed, and the bolt 8 passes through the soft buffer head 6 and is fixed to the head end of the hydraulic jack 2. When the soft buffer head 6 is worn out after being used for a period of time and cannot be used normally, the bolt 8 can be removed and replaced with a new soft buffer head 6, and the replacement is more convenient and quick.

[0034] In some preferred embodiments, protective plates 9 are provided around the base 1, and the height of the protective plates 9 is not lower than the initial height of the hydraulic jack 2 in the retracted state, so as to protect the internal hydraulic jack 2. In other feasible embodiments, the protective plates 9 may also be eliminated to facilitate the disassembly and assembly of the power assembly.

[0035] In other feasible implementations, the protective plate 9 may also be eliminated to avoid interference with the protective plate due to the irregularity of the powertrain, that is, the existence of protruding parts. The specific selection can be made according to actual needs. When the protective plate 9 is not needed, the bolts fixing the protective plate 9 can be removed.

[0036] In some preferred embodiments, an integral buffer pad 10 is connected to the upper end of the plurality of hydraulic jacks 2, and the buffer pad 10 can be used to isolate the hydraulic jacks 2 from the power assembly to be disassembled and assembled, and reduce the oil stains from falling onto the base 1 below. Furthermore, the buffer pad 10 can be made of rubber material, which has a certain elasticity, and can further reduce the problem of damage to the power assembly caused by the head end of the hydraulic jack 2.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
