Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly relates to an angle-adjustable and quickly detachable powertrain device. Background Art

[0002] With people's yearning for a better life, automobiles have become people's daily tools. During the use of vehicles, due to various reasons, it is necessary to repair the vehicle transmission or engine. At this time, it is necessary to remove the powertrain from the vehicle. However, due to the limited space in the vehicle engine compartment, the difficulty of removing the powertrain is greatly increased, and the removal efficiency is reduced. At present, the first step in removing the powertrain is to remove the subframe. After the removal is completed, the powertrain is supported by a flat hydraulic trolley, and then the connection mechanisms related to the powertrain are further removed. Since the bottom of the powertrain is in an uneven state, this operation method may cause the powertrain to fall on the one hand, posing a major safety risk; on the other hand, for some vehicle models, the powertrain has a certain angle with the horizontal plane in the normal state. Using conventional disassembly tooling will make it difficult to remove the powertrain.

[0003] Currently, most of the conventional removals of the powertrain use a lifting platform or a simple support tooling. The removal mainly consists of three steps. The first step is to remove the subframe; the second step is to support the powertrain to be removed with a flat hydraulic trolley or a simple tooling; the third step is to remove the connection mechanisms related to the powertrain.

[0004] Since the bottom of the powertrain is in an uneven state, through this solution, on the one hand, the powertrain may fall, posing a major safety risk; on the other hand, for some vehicle models, the powertrain has a certain angle with the horizontal plane in the normal state. Using conventional disassembly tooling will inevitably force the powertrain to be adjusted to a horizontal angle, resulting in the removal of all connection mechanisms of the powertrain, and it is also very difficult to remove the powertrain from the vehicle.
