  • Patent number: 11920657
    Abstract: A cycloidal reducer includes a reduction unit configured to reduce a torque input and an output unit configured to transfer the reduced output to the outside. A cycloidal rotor that is one constituent element of the reduction unit has a tooth-type protrusion formed in the shape of a circular arc. Thus, the level of difficulty of process is decreased more than when the tooth-type protrusion in the related art is formed in the shape of a broken line. In addition, rotor pins are accommodated in through-holes, respectively, that are equally spaced in the cycloidal rotor. A bushing is formed that fills a gap between the through-hole and the rotor pin is formed in order for the rotor pin to stably transfer rotational power. Accordingly, the advantage of effectively distributing a load and stably transferring a reduction torque to the outside is provided.

  • Publication number: 20210054924
    Abstract: A dial transmission lever device according to an exemplary embodiment of the present invention includes a dial knob, a button guide unit, a plurality of button units, a rubber unit, and a board unit. The dial knob is rotatable from a predetermined reference position and includes a first hole that penetrates the dial knob from one end to the other end of the dial knob. The button guide unit is disposed in the dial knob. The plurality of button units is disposed in the button guide unit. The rubber unit is disposed below the button guide unit and includes protruding portions disposed below the plurality of button units, respectively. The board unit is disposed below the rubber unit. In addition, the dial knob further includes a rotary member disposed in the first hole, coupled to the dial knob, and configured to rotate together with the dial knob.

  • Patent number: 10753458
    Abstract: A transmission control device may be provided that includes a magnet, a magnetic sensor, a slider, a shift lever, and a motion conversion member. The magnetic sensor is fixed to a predetermined position and measures a magnetic field which changes according to a relative position with respect to the magnet. The magnet is disposed at one end of the slider. The shift lever rotates to a position according to a shift level by user operations. When the shift lever rotates, the motion conversion member converts a rotational motion of the shift lever into a linear motion, and moves the slider in a first direction.

  • Patent number: 10605354
    Abstract: A button-type transmission control device includes: a button portion which includes a first area and a second area different from the first area; a hinge disposed under the button portion; and a substrate which is disposed under the hinge. The substrate includes a first terminal placed under the first area and a second terminal placed under the second area. When pressure is applied to the first area, the button portion is inclined such that the first area descends with respect to the hinge, so that the first area contacts the first terminal, and a gear shift position corresponding to the first terminal is selected. When pressure is applied to the second area, the button portion is inclined such that the second area descends with respect to the hinge, so that the second area contacts the second terminal, and a gear shift position corresponding to the second terminal is selected.

  • Patent number: 9851002
    Abstract: A shift control apparatus of a manual transmission is disclosed. To change the gear, the shift control apparatus of a manual transmission according to the embodiment of the present invention includes: a shift lever which is movable in a shift direction and in a select direction; a select lock unit which includes a shaft for limiting the select directional movement of the shift lever; and a controller which controls the select lock unit to limit the select directional movement of the shift lever on the basis of a speed of a vehicle. As a result, a driver can safely shift the gear by preventing unintended shifting to R gear and sense the state of a select lock. Also, the select lock unit is implemented by one solenoid, so that it is possible to reduce the cost thereof, to prevent the overheating of the solenoid, and thus, to extend the life span.
