Problems solved by technology

The currently used parallel-shaft automatic transmission clutch will occupy a part of the axial space, making the axial size of the transmission larger, which affects the layout of the engine and transmission, especially for cars with a transverse engine and front-wheel drive
If the number of gears is increased without increasing the number of transmission shafts, the axial dimension of the transmission will increase; if the number of gears is increased without increasing the number of transmission shafts, the radial dimension of the transmission will increase, which means Both results will increase the volume and weight of the transmission. Therefore, the number of gears in the transmission of the front-wheel-drive car with the transverse engine is not large, which makes the power and economy of the car unsatisfactory, and the smoothness of shifting is poor.

[0030] Such as Figure 4 Shown is a schematic diagram of an example of installing an internal clutch in a gear shifting mechanism of a seven-speed parallel shaft automatic transmission. In the figure, the dotted line connecting the two gears indicates the meshing connection of the two gears. This example consists of three shafts (input shaft 29, output shaft 20 and reverse gear shaft 30), four clutches (reverse gear and first gear clutch 22, second gear third gear clutch 23, fourth gear fifth gear clutch 25 and sixth gear and seventh gear Clutch 27) and four hydraulic shifting mechanisms (reverse and first gear shift pistons 21, second and third gear shift pistons 24, fourth and fifth gear shift pistons 26, and sixth and seventh gear shift pistons 28) composition.

[0031] Reverse gear and first gear clutch 22, second gear and third gear clutch 23 and fourth gear and fifth gear clutch 25 are arranged on the output shaft 20, and sixth gear and seventh gear clutch 27 are arran...

[0035] Such as Figure 5 Shown is an example of installing the built-in clutch in the gear shifting mechanism of a nine-speed parallel shaft automatic transmission. The dotted line connecting the two gears in the figure represents the meshing connection of the two gears. This example also provides the operating force of the clutch by hydraulic pressure. Consists of six shafts (input shaft 49, first intermediate shaft 46, second intermediate shaft 51, first output shaft 41, second output shaft 58, and reverse gear shaft 47), six gear clutches (first gear, third gear clutch 57, fifth gear clutch 56, seventh gear ninth gear clutch 54, reverse gear second gear clutch 42, fourth gear clutch 43 and sixth gear eighth gear clutch 45) and six shift pistons (first gear, third gear shift piston 59, five Gear shift piston 55, seven gears and nine gear shift pistons 52, reverse gear second gear shift piston 40, four gear shift pistons 44, six gear eight gear shift pistons 48) form.

Abstract

The invention discloses a built-in clutch which comprises a mounting shaft, gears and clutches. The gears are sleeved on the mounting shaft, a hollow shaft sleeve is arranged in the mounting shaft, a slot is formed in the shaft sleeve, cavities are arranged on the gears, the clutches are mounted among the cavities and the shaft sleeve, a lever capable of swinging is arranged in the slot, a hammer is arranged at an end of the lever, and the lever is adjacent to the clutches, so that the clutches can be compressed when the hammer of the lever swings towards the clutches, the gears can be jointed with the shaft sleeve, and power can be transmitted. The built-in clutch has the advantages that the built-in clutch and a gear shifting control mechanism of the built-in clutch are based on an existing parallel shaft type gear transmission, so that gears of the transmission can be closely arranged, the axial size of the transmission can be reduced, the volume of the transmission can be decreased, the transmission can be lightened, and the manufacturing cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of automobile transmissions, in particular to a novel clutch and shifting control mechanism of a parallel shaft automatic transmission. Background technique [0002] The clutch of an automobile parallel shaft automatic transmission is a device that engages or interrupts power between a gear or two gears. The currently used parallel-shaft automatic transmission clutch will occupy a part of the axial space, making the axial dimension of the transmission larger, which affects the layout of the engine and transmission, especially for cars with the engine placed transversely and front-wheel drive. If the number of gears is increased without increasing the number of transmission shafts, the axial dimension of the transmission will increase; if the number of gears is increased without increasing the number of transmission shafts, the radial dimension of the transmission will increase, which means Both results will...
