Problems solved by technology

The main disadvantages of this transmission are: (1), less gears, low transmission efficiency, poor dynamic performance, and cannot adapt to the operation of construction machinery under complex working conditions; (2), the shift mode is manual hydraulic shift, and the operation Inconvenient; (3), with a one-way clutch, complex structure, prone to failure; (4), high precision requirements, complex processing
[0003] At present, the common fixed-axis transmissions for construction machinery in China are four-advance and three-reverse transmissions (such as Chinese patent ZL200820167314.0) and four-advance and four-reverse transmissions (such as Chinese patent ZL201020653727.7). The number of gear pairs used in gears is generally 3 to 4 pairs, the transmission efficiency is low, and the operation is inconvenient

Embodiment Construction

[0020] Please check figure 1 and figure 2 , A power shift transmission, such as a power shift transmission suitable for a wheel loader, which includes an input shaft 16, an output shaft 19, two intermediate shafts 17, 18 and an idler shaft 15. The input shaft 16, the idler shaft 15, the first intermediate shaft 17, the second intermediate shaft 18 and the output shaft 19 are arranged in parallel in sequence, and the axial end faces of the input shaft 16, the idler shaft 15 and the first intermediate shaft 17 Triangular arrangement in projection.

[0021] The input shaft 16 is provided with two movable gears 1, 7 and two clutches 21, 20, and the two clutches 21, 20 respectively control the two movable gears 1, 7 to control the movable gear and the axial direction to be in a synchronous rotational connection relationship.

[0022] The output shaft 19 is provided with a fixed gear 13 .

[0023] Described first intermediate shaft 17, it establishes three fixed gears 2,8,9, two...

Abstract

The invention discloses a dynamic power shifting transmission, which includes an input shaft 16, an output shaft 19, two intermediate shafts 17 and 18, and an idler shaft 15. The input shaft 16 is provided with two movable gears 1 and 7 and two clutches 21 and 20; the output shaft 19 is provided with a fixed gear 13; the first intermediate shaft is provided with three fixed gears 2, 8 and 9, two movable gears 3 and 10 and two clutches 22 and 23; the second intermediate 18 is provided with three fixed gears 5, 11 and 12, two movable gears 4 and 14 and two clutches 24 and 25; and the idler shaft 15 is provided with a fixed gear 6. The movable gear 1 and the fixed gear 2 are meshed, the movable gear 7 and the fixed gear 6 are meshed, the fixed gear 2 and the movable gear 4 are meshed, the fixed gear 6 and the fixed gear 8 are meshed, the movable gear 3 and the fixed gear 5 are meshed, the movable gear 10 and the fixed gear 12 are meshed, the fixed gear 9 and the movable gear 14 are meshed, and the fixed gear 11 and the fixed gear 13 are meshed. The dynamic power shifting transmission has the advantages as follows: the gears are rather plentiful, the speed ratio is reasonable and the operation is simple and convenient.

Description

technical field [0001] The invention relates to a power shift transmission, in particular to a power shift transmission suitable for engineering machinery. Background technique [0002] At present, most of the power shift transmissions suitable for construction machinery produced and used in our country are planetary hydraulic transmissions with second forward gear and first reverse gear. The main disadvantages of this transmission are: (1), less gears, low transmission efficiency, poor dynamic performance, and cannot adapt to the operation of construction machinery under complex working conditions; (2), the shift mode is manual hydraulic shift, and the operation Inconvenient; (3), with a one-way clutch, complex structure, prone to failure; (4), high precision requirements, complex processing. [0003] At present, the common fixed-axis transmissions for construction machinery in China are four-advance and three-reverse transmissions (such as Chinese patent ZL200820167314.0)...
