Problems solved by technology

Although the fixed-axis hydraulic automatic transmission has the disadvantages of large volume and small maximum speed ratio, it has few shift actuators. For example, the four-speed fixed-axis hydraulic automatic transmission has 4 shift actuators. There is only one actuator involved, which makes it have the advantages of simple control and low failure rate, which is the main reason why this relatively bulky design has not been eliminated so far

Embodiment

[0014] The modified fixed-shaft six-speed hydraulic automatic transmission has a main shaft 1 and a counter shaft 12, and the two shafts are parallel.

[0015] The first and second gears 2, the third and fourth gears 4, the fifth and sixth gears 6 and the main shaft gear 8 are fixedly installed on the main shaft 1, and the clutches 3, 3 and 4 are respectively installed on the sides of the gears 2, 4 and 6 Clutch 5 and Clutch 7.

[0016] A single planetary row combination gear is installed on the secondary shaft 12, and the planetary carrier 10 is successively fitted with gears 15, 16 and 18 which mesh with the gears 2, 4 and 6 on the main shaft 1, and one side of the planetary carrier 10 is fixedly installed There is a planetary carrier brake 14, and a countershaft gear 9 meshing with the main shaft gear 8 is also set on the countershaft 12, and a sun gear and a countershaft gear clutch 19 are arranged on the shaft of the sun gear 11 and on the side of the countershaft gear 9....

Abstract

The present invention relates to a modified dead axle type hydraulic automatic gear shift with six axle gears, which is characterized in that a single row star arrange on an additional axle of the double-shaft dead axle type hydraulic gear shift having not reverse gear, and the simple structure only with four clutches, an arrester, a single direction clutch has excellent capacity of six advancing gears, a reverse gear. The invention has many shifting gears, high shifting ratio, which is suitable for various military use, civilian use vehicles, particularly for diesel motor vehicle having small shifting range.

Description

technical field [0001] The invention relates to motor vehicle transmissions. Background technique [0002] At present, the hydraulic automatic transmissions used are divided into two types, one is a planetary gear hydraulic automatic transmission, and the other is a fixed shaft hydraulic automatic transmission. The planetary gear hydraulic automatic transmission occupies most of the hydraulic automatic transmission market due to its compact structure, small size and large speed ratio. There are 7-10 actuators, and there are as many as 2-6 actuators involved in each gear. There are high frequency of actuators and long working hours, which makes this design have the disadvantage of high system failure rate. Although the fixed-axis hydraulic automatic transmission has the disadvantages of large volume and small maximum speed ratio, it has few shift actuators. For example, the four-speed fixed-axis hydraulic automatic transmission has 4 shift actuators. There is only one actua...
