Description

Technical Field

[0001] The utility model belongs to the technical field of automobile transfer cases, and in particular relates to a novel transfer case power take-off device. Background Art

[0002] As more and more small vehicles such as pickup trucks are modified into engineering vehicles, people require that pickup trucks and engineering vehicles be equipped with power take-offs to realize power input of their external equipment. However, due to the space layout of small vehicles such as pickup trucks, the installation of sandwich power take-offs, broken axle power take-offs or other forms of power take-offs are restricted. At the same time, due to the different application scenarios of external equipment, the driving conditions of the vehicles when taking power are also different. Some require power take-off when the vehicle is stopped, some require power take-off in two-wheel drive state, and some require power take-off in four-wheel drive state. The power take-off devices currently used on the market can often only meet the power take-off requirements of a certain operating condition of the vehicle, and cannot meet the use requirements of multiple scenarios at the same time.

[0003] Comparative document CN117605815A discloses a new type of power take-off component, including a transfer case module, an auxiliary power take-off A module, an auxiliary power take-off B module, a hydraulic variable pump module, and a hydraulic motor module. However, this document has several shortcomings: 1. It is a split-shaft power take-off method, which involves disconnecting the base vehicle's drive shaft and inserting a power take-off transfer case in the middle. Power is taken off through the rotation of the drive shaft. This solution does not require design changes to the base vehicle's transmission and transfer case, and output power, torque, rotational speed, and speed changes are all limited. 2. The modification is performed by the modification company by disconnecting the drive shaft, which affects the power performance of the base vehicle. Furthermore, due to the influence of the base vehicle's original fuel tank and exhaust pipe, it occupies more space and is more difficult to arrange. Utility Model Content
