Problems solved by technology
[0002] At present, the method of changing the manual transmission of the car to the automatic transmission generally uses the worm gear transmission to connect the hydraulic oil pump to control the automobile gearbox. Downward reverse thrust movement, but worm gear transmission has many disadvantages, such as: low transmission efficiency, easy to produce tooth surface adhesion, short service life, high maintenance frequency, etc.

Embodiment Construction
[0012] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0013] Such as figure 1 and 2 As shown, the guide rail 2 of the invention is fixed on the inner upper part of the frame 1 by screws, the clamper 3 is slidingly connected to the guide rail 2, the rack 4 is connected to the clamper 3 by screws, the gear 5 is connected to the main shaft 6 through a flat key, and the main shaft 6 Installed on the frame 1 through bearings, the oil pump push rod 7 is rigidly connected to the right end of the rack 4, the hydraulic oil pump 8 is fixed on the right side of the frame 1, the servo motor 9 is fixed on the front side of the frame 1, and the output shaft of the motor is connected to the main shaft 6 connected by a coupling. The present invention requires an additional pneumatic control system to control the clamper 3 .
[0014] There is a certain gap between the guide rail 2 and the upper part of the frame 1 to prevent the clamp...

The invention provides a method for changing a manual gear to an automatic gear by using gear-rack transmission, and relates to the technical field of vehicle transmission. The method comprises a servo motor, a hydraulic oil pump, a frame, a guide rail, a clamper, a gear, a rack and the like. The guide rail is fixed at the upper part in the frame through a screw; the clamper is slidingly connected with the guide rail; the rack is connected with the clamper through a screw; the gear is connected with a main shaft through a flat key; the main shaft is mounted on the frame through a bearing; a push rod of the hydraulic oil pump is rigidly connected with the right end of the rack; the hydraulic oil pump is fixed on the right side of the frame; the servo motor is fixed on the front side of the frame; and a motor output shaft is connected with the main shaft through a coupling. The hydraulic oil pump is used for controlling a vehicle transmission to realize automatic gear shifting; and the clamper on the guide rail enables the rack to achieve a braking function to prevent an oil pump push rod acted with the oil pressure from moving when the servo motor dose not work. The method is simple in structure, convenient in disassembly, and safe and durable.
Description
Technical field: [0001] The invention relates to the technical field of automobile transmission, and specifically relates to a method for changing a manual transmission of an automobile into an automatic transmission by using rack and pinion transmission. Background technique: [0002] At present, the method of changing the manual transmission of the car to the automatic transmission generally uses the worm gear transmission to connect the hydraulic oil pump to control the automobile gearbox. The bottom pushes back and moves, but the worm gear transmission has many disadvantages, such as: low transmission efficiency, easy tooth surface adhesion, short service life, high maintenance frequency, etc. Invention content: [0003] The purpose of the present invention is to provide a simple structure, easy disassembly, safe and durable, and has a braking function, using rack and pinion transmission to change the manual transmission method of the car into automatic transmission. ...
