Description

Technical Field

[0001] The present invention relates to the technical field of transmissions, and in particular to a full-gear continuously variable transmission with stepless rotation speed regulation and a use method thereof. Background Art

[0002] The internal combustion engine transmission, also known as the automobile transmission, is one of the core components of an internal combustion engine-driven vehicle. During the driving process of the vehicle, it can produce different speed ratios between the engine and the wheels according to the requirements of the engine speed and the actual driving speed of the wheels, thereby realizing the conversion and transmission of power.

[0003] Traditional engines that use MT, AMT, DCT, AT, and CVT transmissions require a clutch or torque converter to start and change speeds. They have relatively high manufacturing costs, are easily worn out during long-term use, resulting in a short lifespan, and have relatively complex overall control, requiring precise control of the clutch, torque converter and other components to work in coordination.

[0004] Therefore, in order to solve the problem that the above-mentioned traditional transmission requires a clutch or a torque converter to start and shift speed, a full-gear continuously variable transmission with stepless speed adjustment can be designed. In the main structure of the full-gear structure, the following can be achieved: clutch state, forward continuously variable shift state, and reverse gear continuously variable shift state. Summary of the invention

[0005] In order to overcome the problem that traditional transmissions require a clutch or torque converter to start and change speed.

[0006] The technical solution of the present invention is: a full-gear continuously variable transmission with stepless speed adjustment, comprising an input shaft, a planetary carrier gear, a motor gear, a control motor, a planetary carrier body, a sun gear and a planetary wheel; a planetary carrier gear is installed on the outside of the input shaft, the side end of the planetary carrier gear is meshingly connected with the motor gear, a control motor is installed on the outside of the motor gear, a planetary carrier body is installed on the outside of the planetary carrier gear, a planetary wheel is installed on the inside of the planetary carrier body, both sides of the planetary wheel are meshingly connected with the sun gear, and the planetary carrier gear, the planetary carrier body and the planetary wheel together constitute a planetary disk.

[0007] Preferably, one side of one group of sun gears close to the planetary carrier gear is connected to the input shaft, and one side of another group of sun gears away from the planetary carrier gear is connected to the output shaft.

[0008] Preferably, a motor seat is installed at the lower end of the control motor, an output shaft is installed at the output end of the control motor, and the outer side of the output shaft is connected to one side of the planetary gear.

[0009] Preferably, bearing seats are installed on the outer sides of the input shaft and the output shaft.

[0010] A method for using a full-gear continuously variable transmission with a continuously variable rotation speed adjustment includes the full-gear continuously variable transmission with a continuously variable rotation speed adjustment as described above, and the steps are as follows;

[0011] Step 1: When power is input to the input shaft, the planetary disc will rotate driven by friction. At this time, if the speed of the planetary disc is adjusted, the speed of the output shaft at the output end will also change, and the speed of the output end changes linearly without step difference;

[0012] Step 2: The gear ratio of the planetary carrier gear to the sun gear is 1:1. If the power shaft speed is 100r / min, the planetary carrier body and the power shaft rotate in the same direction of 100r / min, then the output shaft is 0r / min; when the power shaft is 100r / min and the planetary carrier is adjusted to 99 turns in the same direction, the output shaft rotates 1 circle, and the direction is opposite to the input shaft; if the number of teeth of the planetary carrier gear and the power shaft sun gear is consistent, then the input speed = planetary disk speed + output shaft speed, for example: input speed 100r / min = planetary disk speed 55r / min + output shaft speed 45r / min; if the input shaft rotates clockwise at 100r / min and the planetary disk rotates clockwise at 105r / min, then the output shaft and the input shaft rotate clockwise at 5r / min, which is equivalent to reverse gear;

[0013] Step 3: If the input shaft rotates clockwise at 100r / min, and the planetary plate and the input shaft rotate counterclockwise at 5r / min, then the output shaft and the input rotate counterclockwise at 105r / min, which is equivalent to the acceleration gear;

[0014] Step 4: If the planetary disk is locked and does not rotate, the input and output speeds are the same but in opposite directions. When the number of teeth on the sun gear and the planetary carrier gear are inconsistent, the planetary disk speed must be adjusted. The above transmission shaft system still exists, so by controlling and adjusting the planetary disk speed, the input shaft speed can be adjusted steplessly in the system.

[0015] Preferably, there are no requirements for the gear shapes and tooth profiles of the planetary carrier gear, motor gear, sun gear and planetary gear, and there are no requirements for the meshing form of the sun gear and the planetary gear.

[0016] Preferably, the device for controlling the direction of the planetary disk rotation speed can be of various types, including speed regulating motor control, torque converter control, electromagnetic resistance control, friction wheel or friction plate control, with appropriate matching and transmission loss ≤6%.

[0017] Beneficial effects of the present invention: The present invention adopts the method of controlling and adjusting the speed difference between the planetary disk and the input shaft to achieve the effect of clutchless stepless speed change. The tooth ratio of the planetary carrier gear and the sun gear is 1:1. If the power shaft speed is 100r / min, the planetary carrier body and the power shaft rotate in the same direction of 100r / min, and the output shaft is 0r / min; when the power shaft is 100r / min and the planetary carrier is adjusted to 99 turns in the same direction, the output shaft rotates 1 circle at this time, and the direction is opposite to that of the input shaft; if the number of teeth of the planetary carrier gear and the power shaft sun gear is consistent, the input speed = planetary disk speed + output shaft speed, so by controlling and adjusting the planetary disk speed, the input shaft speed can be steplessly adjusted in the system, and the following can be achieved: clutch state, forward stepless speed change state, and reverse gear stepless speed change state.

[0022] A full-gear continuously variable transmission with stepless speed adjustment and a method of using the same include the full-gear continuously variable transmission with stepless speed adjustment as described above, and the steps are as follows;

[0023] Step 1: When power is input to the input shaft 1, the planetary disc will rotate driven by friction. At this time, if the speed of the planetary disc is adjusted, the speed of the output shaft 8 at the output end will also change, and the speed of the output end changes linearly without step difference;

[0024] Step 2: The gear ratio of the planetary carrier gear 2 and the sun gear 6 is 1:1. If the power shaft speed is 100r / min, the planetary carrier body 5 and the power shaft rotate in the same direction of 100r / min, then the output shaft 8 is 0r / min; when the power shaft is 100r / min and the planetary carrier is adjusted to 99 turns in the same direction, the output shaft 8 rotates 1 circle, and the direction is opposite to the input shaft 1; if the number of teeth of the planetary carrier gear 2 and the power shaft sun gear 6 is consistent, then the input speed = planetary disk speed + output shaft 8 speed, for example: input speed 100r / min = planetary disk speed 55r / min + output shaft 8 speed 45r / min; if the input shaft 1 rotates clockwise at 100r / min and the planetary disk rotates clockwise at 105r / min, then the output shaft 8 and the input shaft 1 rotate clockwise at 5r / min, which is equivalent to reverse gear;

[0025] Step 3: If the input shaft 1 rotates clockwise at 100 r / min, and the planetary plate and the input shaft 1 rotate counterclockwise at 5 r / min, then the output shaft 8 and the input shaft 1 rotate counterclockwise at 105 r / min, which is equivalent to the acceleration gear;

[0026] Step 4: If the planetary disk is locked and does not rotate, the input and output speeds are consistent but in opposite directions. When the number of teeth of the sun gear 6 and the planetary carrier gear 2 are inconsistent, the planetary disk speed needs to be adjusted. The above transmission shaft system still exists, so by controlling and adjusting the planetary disk speed, the speed of the input shaft 1 can be steplessly adjusted in the system. The gear shape and tooth profile of the planetary carrier gear 2, the motor gear 3, the sun gear 6 and the planetary gear 7 are not required, and the meshing form of the sun gear 6 and the planetary gear 7 is not required.
