Multi-functional coaxial multi-head output rear transfer case

Abstract

The invention discloses a multi-functional coaxial multi-head output rear transfer case. The multi-functional coaxial multi-head output rear transfer case comprises a gearbox, a clutch arranged before the gearbox and a plurality of transfer cases arranged at the rear end of the gearbox, wherein an input shaft is fixedly mounted in the gearbox, and the two ends of the input shaft respectively extend into the clutch and the transfer cases; each transfer case comprises a transfer case shell, a first gear, a second gear, a third gear, a first output shaft and a second output shaft; the first gear, the second gear and the third gear are sequentially connected in an engagement manner, the first gear is arranged on the input shaft, the third gear is arranged on a second shaft, a third shaft and the second shaft are coaxially arranged, one end of the third shaft is connected with a gear engagement gear sleeve through an external spline, a spline groove is formed in the inner side of the gear engagement gear sleeve, the external spline corresponding to the spline groove is arranged on the second shaft, and a gearshift device is further connected to the gear engagement gear sleeve; and the second shaft and the third shaft are respectively connected with a first output flange plate and a second output flange plate. The multi-functional coaxial multi-head output rear transfer case is simple in structure and convenient to maintain and can carry out multi-head output.

Description

technical field [0001] The invention relates to a multi-shaft output transmission device, in particular to a multifunctional coaxial multi-head output rear transfer case. Background technique [0002] Through the combination of the gearbox and the transfer case, the power provided by the vehicle engine can be supplied to the needs of the vehicle, such as the self-unloading of the body of the dump truck, the water spray pump of the fire truck, and the automatic mixing of the cement mixer truck. An indispensable key component, the current transfer case generally can only provide one additional power output, and has a complex structure and takes up a lot of space. [0003] The invention patent of the patent application number 201420309789.4, "Symmetrical dual output power take-off" discloses a symmetrical dual output power take off, which includes a housing and an output device. There is a cavity in the middle of the housing and two sides of the cavity. Symmetrical support hol...

[0003] The invention patent of the patent application number 201420309789.4, "Symmetrical dual output power take-off" discloses a symmetrical dual output power take off, which includes a housing and an output device. There is a cavity in the middle of the housing and two sides of the cavity. Symmetrical support holes, the support holes are provided with connecting flanges, the output device with symmetrical output ends is located in the cavity of the housing, and the symmetrical output ends of the output device pass through the through holes of the two connecting flanges respectively. It achieves the purpose of outputting two powers from one input end, but the two output ends share one output shaft, and the power must be output at the same time when in use, which will waste part of the power, and the structure is complex and takes up a lot of space
