Power takeoff and power taking method

Abstract

The invention discloses a power takeoff and a power taking method. The power takeoff is arranged between a vehicle gearbox and a vehicle transmission shaft and comprises a driving wheel, an input shaft, a gear ring, an output shaft, an engagement sleeve, a shifting fork and a power source. The position of the engagement sleeve changes along with changes of the position of the shifting fork. Underthe action of a first input signal, a movable component of the power source drives the shifting fork to move to a first position, the gear ring is connected with the driving wheel through the engagement sleeve, and power of the vehicle gearbox is transmitted to vehicle field engineering power takeoff equipment through the input shaft, the gear ring, the engagement sleeve and the driving wheel in sequence. In case of no input signal or under the action of a second input signal, the shifting fork is in a second position, the gear ring is connected with the output shaft through the engagement sleeve, and the power of the vehicle gearbox is transmitted to the vehicle transmission shaft through the input shaft, the gear ring, the engagement sleeve and the output shaft in sequence. The power takeoff is ingenious in structure, fewer in part, and convenient to refit through the installation position, has no influence on the existing frame performance of a vehicle. The power taking difficulty is effectively reduced, and the power taking efficiency is greatly improved.

Description

technical field [0001] The present application relates to the technical field of vehicle accessories, in particular to a power take-off and a power take-off method. Background technique [0002] The power take-off, also known as the power take-off, is mainly used to obtain and transmit the power of the engine or gearbox to the engineering power take-off equipment outside the vehicle, such as a lift pump. [0003] At present, the power take-offs of the vehicle chassis are mostly installed at the output end of the engine or the output end of the gearbox to obtain power, which requires a major change in the structure of the vehicle engine or gearbox. The internal layout of mature vehicles of many models is compact, and most of the existing power take-offs adopt gear transmission, or use pneumatic, hydraulic, or mechanical power sources. Therefore, if you need to use the existing power take-off, you need to The difficulty and complexity of refitting are very large, and it is di...

Problems solved by technology

The internal layout of mature vehicles of many models is compact, and most of the existing power take-offs use gear transmission, or use pneumatic, hydraulic, or mechanical power sources. Therefore, if you need to use the existing power take-off, you need to The difficulty and complexity of modification are very high, and it is difficult to quickly realize vehicle modification in a short period of time, which increases the difficulty of power extraction and affects the efficiency of power extraction
