Problems solved by technology

This method is not easy to adjust the gear control speed, the gear shifting speed may be fast or slow, and it is difficult to control
In terms of accuracy, if the "rotary motor + ball screw" is not equipped with a detection feedback control device, the repeat positioning accuracy is relatively low, and it is affected by processing and installation accuracy.

Embodiment 1

[0032] This embodiment provides an automatic control gear shifting device based on a linear motor, including a linear gear shift mechanism 14; The subassembly, the moving subassembly slides in the stator assembly, driving the stopper rod 1 to move;

[0033] The stator assembly includes: a control circuit board 9, a stator base 10, a permanent magnet 11, and a movable limit sensor 16; the control circuit board 9 is placed on the stator base 10, and the stator base 10 is provided with a guide groove, so The above-described guide grooves include guide grooves I18, guide grooves II19 and guide grooves III20 arranged from top to bottom, and guide groove II19 is placed between guide grooves I18 and guide grooves III20; permanent magnets 11 are symmetrically distributed in guide grooves II19, which can be The movement limit sensor 16 is placed in the guide groove I18, the magnetic pole direction of the permanent magnet 11 is perpendicular to the direction of the guide groove II19, an...

Embodiment 2

[0039] The linear shift mechanism 14 described in embodiment 1 is installed and fixed in the hollow armrest box 15, and the shift dust cover is removed earlier before installation, and the figure 2 A plurality of fixing bolts shown fix the base of the linear shift mechanism 14 in the center control armrest box 15 inside.

[0040] The permanent magnet 11 is fixed on the stator base 10. The permanent magnet is a 20mmx20mmx20mm square magnetic pole. The direction of the magnetic pole is perpendicular to the direction of the guide groove II19. Fixed, easy to move and adjust the position of the permanent magnet. The mover slider 8 of the mover assembly and the stator assembly cooperates with the guide groove III20, and lubricating oil is applied in the guide groove III20, so that the mover slider 8 can slide freely in the guide groove III20;

[0041] The mover coil 7 can move linearly under the magnetic field after being energized, thereby driving the blocking rod 1 to move back ...

Abstract

The invention discloses an automatic control gear shifting device based on a linear motor. The automatic control gear shifting device includes a linear gear shifting mechanism. The linear shifting mechanism includes a stator assembly, an active cell assembly and a shift lever, the shift lever passes through the active cell assembly, and the active cell assembly slides in the stator assembly to drive the shift lever to move. The automatic control gear shifting device is applied to an automatic driving system, realizes high-efficiency change of gear positions, can not affect the operation and aesthetics of an original car, and can be used for automatic control gear shifting mechanisms of various types of vehicles.

Description

technical field [0001] The invention relates to an automatic control shifting device, in particular to an automatic control shifting device based on a linear motor. Background technique [0002] In the field of automatic driving vehicles, the shift control of automatic transmission vehicles has not been well broken through. How to make the parking gear P, reverse gear R, neutral gear N, and driving gear D of automatic transmission vehicles realize different situations under various conditions? Gear replacement has become a new topic. Autonomous driving was first used for vehicle road tests, and was applied to electric driving robot devices that replaced human drivers for vehicle tests, especially durability tests. The traditional car test driving robot uses the mechanical transmission form of the gear shift manipulator to switch gears. The advantage of this form is that it can be positioned accurately and can be used for a variety of models. complex. [0003] At present, ...
