Description

Technical Field

[0001] This invention relates to a gear-type clutch for automobiles, and a transmission structure for applying the clutch to the transmission of a hybrid vehicle. Background Technology

[0002] Currently, the two- or three-shaft parallel-shaft manual transmissions (MT) commonly used in commercial vehicles, passenger cars, and microcars become what is commonly known as AMT (Automated Manual Transmission) when an automatic control clutch and shifting system are added. AMTs have many advantages, including simple structure, low cost, ease of manufacturing, convenient maintenance, high transmission efficiency, and are particularly suitable for China's national conditions. However, due to the inherent defect of power interruption during gear shifts, the resulting jerking leads to poor driving comfort, preventing its widespread adoption and making it rarely used in hybrid vehicles. Currently, the mainstream hybrid technology is largely monopolized by foreign companies. Domestic hybrid vehicles mainly use a dual-motor combined with a planetary gear system structure. However, the use of two drive motors results in complex structure, greater control difficulty, increased vehicle cost, and increased difficulty in overall vehicle layout. Summary of the Invention

[0003] The technical problem this invention aims to solve is to provide a single-motor dual-mode electromechanical coupling transmission with two different transmission modes for the application of hybrid technology in various vehicles, including commercial vehicles, passenger vehicles, and microcars, equipped with both AMT and MT transmissions. In addition to meeting the requirements of all driving conditions for hybrid vehicles, this invention also overcomes the power interruption that occurs during gear shifts in AMT transmissions, thereby improving driving comfort.

[0004] The technical solution of the present invention is as follows:

[0005] A dual-mode switching clutch includes a torque output shaft and a torque input shaft. An input driven engagement gear is mounted on the torque input shaft, and a driving engagement gear is loosely fitted on it. The input driven engagement gear and the input driving engagement gear are controlled to be engaged by an input engagement gear ring. An output driven engagement gear is mounted on the torque output shaft, and an output driving engagement gear is loosely fitted on it. The output driven engagement gear and the output driving engagement gear are controlled to be engaged by an output engagement gear ring. The input engagement gear ring and the output engagement gear ring are mounted on a dual-mode shift fork.

[0006] The input active engagement gear and the output active engagement gear are each connected to a transmission gear on their sides, and these two transmission gears are constantly meshed.

[0007] The clutch has three operating states: 1. When the input driven engagement gear and the input driving engagement gear are connected through the input engagement gear ring, the output driven engagement gear and the output driving engagement gear are separated; 2. When the output driven engagement gear and the output driving engagement gear are connected through the output engagement gear ring, the input driven engagement gear and the input driving engagement gear are separated; 3. The input driven engagement gear and the input driving engagement gear are separated, and the output driven engagement gear and the output driving engagement gear are separated.

[0008] The dual-mode switching clutch is mounted on the side of the three-shaft transmission. The output shaft and intermediate shaft of the three-shaft transmission serve as the torque output shaft and torque input shaft of the dual-mode switching clutch, respectively.

[0009] The input drive gear of the dual-mode switching clutch is coaxially mounted on the side of the input active engagement gear and together they are loosely fitted on the intermediate shaft. The output drive gear is mounted on the side of the output active engagement gear and together they are loosely fitted on the output shaft. The input drive gear is driven by the motor's drive gear.

[0010] The intermediate shaft is equipped with intermediate shaft high and low gear bushings, on which are installed input drive engagement gear, intermediate shaft high gear drive gear, and intermediate shaft low gear drive gear. The output shaft is equipped with output shaft high and low gear bushings, on which are installed output drive engagement gear, output shaft high gear driven gear, and one-way clutch. The output shaft low gear driven gear is mounted on the output shaft high and low gear bushings via the one-way clutch. The intermediate shaft high gear drive gear and the output shaft high gear driven gear mesh, and the intermediate shaft low gear drive gear and the output shaft low gear driven gear mesh.

[0011] The motor and output shaft are mounted coaxially. Intermediate shaft transition gears are installed on the high and low gear bushings of the intermediate shaft, and the motor drive gear meshes with the intermediate shaft transition gears.

[0012] A single-motor dual-mode electromechanical coupling transmission includes the aforementioned dual-mode switching clutch. The dual-mode switching clutch is mounted on the side of a dual-shaft transmission. The output shaft and input shaft of the dual-shaft transmission serve as the torque input shaft and torque output shaft of the dual-mode switching clutch, respectively. An input drive gear is coaxially mounted on the side of the input active engagement gear and loosely fitted onto the input shaft together. An output drive gear is mounted on the side of the output active engagement gear and loosely fitted onto the output shaft together. The input drive gear and the output drive gear are constantly meshed.

[0013] The motor drive gear meshes with the input shaft transition gear, and the input shaft transition gear and the input transmission gear are coaxially mounted on the input shaft.

[0014] A single-motor dual-mode electromechanical coupling transmission employing the aforementioned dual-mode switching clutch is disclosed. The dual-mode switching clutch is mounted on the side of a dual-shaft transmission. The output shaft and input shaft of the dual-shaft transmission serve as the torque input shaft and torque output shaft of the dual-mode switching clutch, respectively. An input shaft high / low gear sleeve is mounted on the input shaft, and an input drive engagement gear, an input shaft high-gear drive gear, and an input shaft low-gear drive gear are mounted on the input shaft high / low gear sleeve. An output shaft high / low gear sleeve is mounted on the output shaft, and an output drive engagement gear, an output shaft high-gear driven gear, and a one-way clutch are mounted on the output shaft high / low gear sleeve.

The input shaft high-gear drive gear and the output shaft high-gear driven gear mesh, and the input shaft low-gear drive gear and the output shaft low-gear driven gear mesh.

[0015] The motor, input shaft, and output shaft are installed side by side. The input drive engagement gear, the high-end drive gear, and the low-end drive gear are arranged sequentially from left to right on the high and low end bushings of the input shaft. The motor drive gear is connected to the high-end drive gear of the input shaft through an intermediate transition gear.

The input shaft high and low gear sleeves are arranged from left to right as follows: input shaft high and low gear transmission gear, input shaft low gear drive gear, input shaft high gear drive gear, and input drive engagement gear. The motor drive gear is connected to the input shaft high and low gear transmission gear through an intermediate transition gear.

From left to right, the input shaft high and low gear bushings are arranged with the input drive engagement gear, the input shaft high gear drive gear, the input shaft low gear drive gear, and the input shaft transition gear. The motor drive gear and the input shaft transition gear mesh.

[0018] The beneficial effects of this invention are:

[0019] This invention achieves transmission mode switching by engaging and disengaging a mode-switching clutch. This transmission mode switching not only better meets the vehicle's power demands under different driving conditions, but also, especially during gear shifts, allows the electric motor to transfer power through the output shaft, thus avoiding power interruption and eliminating driving jerks. This provides a new avenue for the promotion and popularization of hybrid technology and has significant practical implications for enhancing the core competitiveness of domestically produced automobiles.

[0029] Example 1: This example is a dual-mode switching clutch, including a torque output shaft and a torque input shaft. An input driven engagement gear 31 is mounted on the torque input shaft, and a driving engagement gear 32 is loosely fitted. The engagement of the input driven engagement gear 31 and the input driving engagement gear 32 is controlled by an input engagement gear ring 4. An output driven engagement gear 33 is mounted on the torque output shaft, and an output driving engagement gear 34 is loosely fitted.

A transmission gear is connected to the side of each of the input driving engagement gear 32 and the output driving engagement gear 34; these two transmission gears are constantly meshed.

[0030] This clutch can be installed on two-shaft or three-shaft transmissions, such as... Figure 1 When applied to a two-shaft transmission, the dual-mode switching clutch 7 is mounted on the side of the two-shaft transmission. The output shaft 2 and input shaft 1 of the two-shaft transmission serve as the torque input shaft and torque output shaft of the dual-mode switching clutch 7, respectively. The input drive engagement gear 32 is coaxially mounted on the side of the input transmission gear 8 and loosely fitted onto the input shaft 1.

When the double shift fork 37 is in the left position, the input driven engagement gear 31 and the input driving engagement gear 32 are connected through the input engagement gear ring 4, and the output engagement gear ring 5 is only fitted on the output driven engagement gear 33, while the output driven engagement gear 33 and the output driving engagement gear 34 are separated; 2.
