Description

An automatic shift mechanism for a manual transmission

technical field

The invention belongs to a gearbox, in particular to an automatic shift mechanism of a manual transmission.

Background technique

At present, automobile transmissions generally adopt two modes: manual transmission and automatic transmission: automatic transmission adapts to changes in external road conditions through automatic shifting of transmission gears, thereby significantly reducing labor intensity and manipulation difficulty. Although cars with automatic transmissions have this advantage. However, since the automatic transmission transmits torque through the hydraulic torque converter and requires a very complicated control system and mechanism to complete the gear change and power transmission, the automatic transmission has a large energy loss, low transmission torque, high manufacturing cost, and cannot drive heavy-duty vehicles. The gear shifting requirements of construction machinery and large trucks make it difficult to apply to heavy vehicles. Existing automobile manual transmission as shown in Figure 1, comprises body 2, is provided with two selection and shift cross shafts 3,5 directly above body 2, selects and shifts cross shafts 3,5 and is respectively provided with shift dial Rods 4, 5, the driver manipulates the shift paddles 4, 5 through the shift lever. Manual transmissions are complicated to operate and require drivers to have a higher level of operation.

Contents of the invention

The purpose of the present invention is to propose an automatic gear shifting mechanism of a manual transmission to improve the comfort and convenience of operation while maintaining the advantages of the existing manual transmission such as simple structure, fuel saving and low cost.

The technical scheme that realizes the object of the present invention adopts is as follows:

The automatic shifting mechanism of manual transmission comprises a transmission body, two selector shift horizontal shafts arranged on the body, a motor drive unit and a vehicle-mounted central processing unit (ECU); The horizontal shaft is connected; the vehicle-mounted central processing unit (ECU) is connected with the motor drive device through a signal output line, and is connected with a sensor arranged at a corresponding part of the vehicle through a signal input line.

Beneficial effects of the present invention:

The automatic shift mechanism provided by the present invention can perform automatic shift operation on the manual transmission through the motor drive device according to the instruction of the vehicle-mounted central processing unit (ECU), and inherits the characteristics of high torque output, fuel saving and low cost of the manual transmission Basically, it has the advantages of comfort and convenience in operation of an automatic transmission, and can be applied to large trucks and public transport vehicles.

The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

Detailed ways

As shown in Figure 2, the automatic shifting mechanism of the manual transmission includes a transmission body 2, two horizontal shafts 3, 5 for shifting gears arranged on the body 2, servo motors 6, 4 of the motor drive device, and an on-board central processing unit (ECU) 8; the servo motors 6 and 4 are respectively connected with the two horizontal shafts 3 and 5 for gear selection; the vehicle-mounted central processing unit (ECU) 8 is connected with the servo motors 6 and 4 through the signal output circuit 7, and the signal input circuit 9 is connected with the sensor 10, and the sensor 10 includes several sensors S1-Sn arranged on corresponding parts of the automobile.

The motor drive device among the present invention can also adopt stepper motor.

A series of signals during the running of the car, such as speed signal, throttle position, throttle opening, etc., are transmitted to the vehicle central processing unit (ECU) 8 by the sensors S1-Sn located at the corresponding parts through the signal input line 9, and the vehicle central processing unit (ECU) 8. After processing, the processing unit (ECU) 8 transmits the control commands to the servo motors 6 and 4 through the signal output line 7, controls the servo motors 6 and 4 to work, and drives the horizontal shafts 3 and 5 to rotate, thereby realizing the gear shifting of the transmission operate.

When the automobile is in parking or other needs to place the transmission gear in neutral, the servo motors 4 and 6 do not work. When it is necessary to shift the gear to the first gear, the servo motor 4 rotates clockwise for a certain angle, and the servo motor 6 rotates clockwise for a certain angle; when it is necessary to shift the gear to the second gear, the servo motor 4 rotates clockwise for a certain angle, and the servo The motor 6 rotates counterclockwise at a certain angle; when the gear needs to be shifted to the third gear, the servo motor 4 does not rotate (that is, does not work), and the servo motor 6 rotates clockwise at a certain angle; when the gear needs to be shifted to the fourth gear, Servo motor 4 does not rotate (that is, does not work), and servo motor 6 rotates counterclockwise for a certain angle; when the gear needs to be shifted to 5th gear, servo motor 4 rotates counterclockwise for a certain angle, and servo motor 6 rotates clockwise for a certain angle; When the gear position needs to be shifted to reverse, the servo motor 4 rotates counterclockwise by a certain angle, and the motor 6 rotates counterclockwise by a certain angle.
