Description

Technical Field

[0001] The utility model relates to the technical field of tractor transmission system assembly, in particular to a transfer case assembly stand for supporting a transmission system. Background Art

[0002] The transfer case and drivetrain are crucial components of a tractor's powertrain, transferring engine power to the wheels to propel the tractor. The transfer case, a crucial component of four-wheel-drive vehicles, distributes engine power to the rear axle, or to both the front and rear axles, enabling switching between two-wheel-drive and four-wheel-drive modes. To enhance operator comfort, the transfer case assembly requires the drivetrain to be placed on a fixed, supported assembly platform, allowing for seated, bottom-up assembly.

[0003] However, due to the excessive number of vehicle types at this stage and the vastly different sizes of transmission systems of different vehicle types, the existing fixed-support assembly benches have a simple structure and cannot be adjusted. They cannot adapt to all vehicle types and cannot meet the transmission system support requirements of all existing vehicle types, resulting in an excessive number of assembly benches for different vehicle types on site and low space utilization. In addition, the existing assembly benches do not provide firm support for transmission systems with some support surfaces being unconventional planes, and cannot provide a safe and reliable transfer case assembly environment, posing certain safety hazards. Utility Model Content

[0004] In order to solve the above technical problems existing in the prior art, the utility model provides a transfer case assembly stand for supporting a transmission system.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] The utility model provides a transfer case assembly stand for supporting a transmission system, comprising a frame body, on which a first support assembly and a second support assembly are relatively provided, and a third support assembly is spaced apart from the first support assembly and the second support assembly; the first support assembly and the second support assembly can be close to or away from each other, and the distance between the first support assembly and the third support assembly and the distance between the second support assembly and the third support assembly can be adjusted.

[0007] By adopting the above technical solution provided by the utility model and adopting an adjustable support component structure, the distance in multiple directions can be adjusted, thereby supporting transmission system structures of different models and sizes and achieving compatibility with various vehicle models.

[0008] On the basis of the above technical solution, the present invention can also make the following technical improvements:

[0009] Furthermore, the frame includes a first bracket and a second bracket, the first support assembly and the second support assembly are arranged on the first bracket, and the third support assembly is arranged on the second bracket.

[0015] Furthermore, a first wedge-shaped piece is provided on the first support block, and a second wedge-shaped piece is provided on the second support block.

[0016] The beneficial effect of adopting the above further technical solution is that when used to support a vehicle having an unconventional planar transmission system structure, the angle design formed between the wedge-shaped member and the support block facilitates the support of the non-planar support system.

[0017] Furthermore, the first fixing member is provided with a plurality of through holes 1, and the plurality of through holes 1 are respectively used for the first pin shaft and the second pin shaft to pass through, the first pin shaft is used to fix the horizontal position of the first fixing member, and the second pin shaft is used to fix the vertical position of the first fixing member.

[0020] Furthermore, the third supporting assembly includes a third supporting mechanism and a third connecting mechanism connected to each other, and the third connecting mechanism is plugged into the bracket.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is that the third support mechanism is inserted into the second bracket to increase the support plane, and the position of the third support mechanism is adjusted by adjusting the insertion length, thereby taking into account the support of the transmission system structure of different vehicle models.

[0022] Furthermore, the frame is also provided with a trigger placement rack, a sleeve placement rack, a tool placement rack and a parts box placement rack.

[0023] The beneficial effect of adopting the above-mentioned further technical solution is that it is convenient for employees to place and take out various assembly tools and parts, thereby improving the assembly convenience of employees.

[0025] The utility model provides a transfer case assembly stand for supporting a transmission system, which adopts an adjustable support component structure and can achieve adjustable distances in multiple directions, thereby being able to support transmission system structures of different models and sizes and achieving compatibility with various vehicle models.
