Embodiment 1

[0056] like figure 1 , the basic module unit of the transfer case is a transfer case including three parallel shafts distributed up and down, specifically including the input shaft assembly, the intermediate shaft assembly and the output shaft torque splitting device, and the three parallel shafts are the input shaft, The second shaft and the third shaft, the input shaft system assembly includes the input shaft, gear one, gear two and shift mechanism one, with two gears of high speed gear and low speed gear. Gear 1 is a small gear, gear 2 is a large gear, gear 1 has a radius of 11 dedendum circles smaller than gear 2’s 12 dedendum circles, and the inner rings of gear 1 and gear 2 are connected to the input shaft through bearings; shifting mechanism 1 is bidirectional shifting Mechanism, the shifting mechanism is constantly meshed with the input shaft through splines. Shifting mechanism 1 is combined with gear 1 by moving to the left to realize the fixed connection of gear 1 a...

Embodiment 2

[0074] The difference from Embodiment 1 is that in this embodiment, the through main reduction module 4 is inserted and installed at port 2 21, which is used to shorten the length of the chassis of the all-terrain crane; see Figure 4 As shown, insert the through main reducer module between the front output assembly and differential lock 1 in the basic module unit of the transfer case, cancel the transmission shaft between the front output shaft assembly of the transfer case and differential lock 1, and obtain Through the integrated structure of the axle box. The integrated structure of the through-axle box is mainly suitable for all-terrain crane models with dual engines, a short distance between the front and rear of the vehicle chassis, and four or six mechanical drive axles. The main advantage of the integrated structure of the through-axle box is that it eliminates the transmission shaft between the front output assembly and the differential lock 1, shortens the length of...

Embodiment 3

[0081] Compared with the through-bridge main reduction module, the off-bridge main reduction module has no inter-axle differential assembly, and the rest of the structure is the same. The bridge main reduction module itself has no power output at ordinary times, and the differential lock four is installed on the through shaft two 59. When the whole vehicle of the all-terrain crane is on uneven road or climbing conditions, the driving force of the whole vehicle is insufficient due to the small ground adhesion of some driving axles. The speed lock assembly is transmitted to the off-bridge main reduction module itself to increase the driving force of the vehicle;

[0082] The off-bridge main reduction module 5 includes gear ten 50, gear eleven 51, gear twelve 52, gear thirteen 53, differential lock four 54, differential lock five 55, differential five 56, output axle shaft three 57, Output half shaft four 58 and through shaft two 59,

[0083] Through shaft 2 59 is fixedly conne...

Abstract

The invention discloses a modular transfer case for all-terrain cranes. The basic module unit of the transfer case includes port one, port two, port three and port four. The subtracting module or the main reducing module of the off-bridge is inserted and installed at the second port, and the power take-off module is inserted and installed at the first port. Different functional modules are used to meet the operational needs of different working conditions, which is conducive to reducing research and development costs.

Description

technical field [0001] The invention relates to a modular transfer case for all-terrain cranes, belonging to the technical field of transfer cases. Background technique [0002] The through main reducer refers to the disconnected drive axle main reducer including the inter-axle differential and the through shaft; the off-bridge main reducer only has the through shaft, which is the disconnected drive axle main reducer without the inter-axle differential; The force device is an auxiliary power output mechanism that provides power to the crane turntable, jib and winch during hoisting operations. [0003] As a high-end product of crane machinery, all-terrain cranes have the advantages of high-speed driving and high off-road performance, and are widely used in major projects such as wind power, oil fields and petrochemicals. The transfer case is the key core component of the transmission system of the all-terrain crane chassis. It is arranged between the gearbox and the drive ax...
