Transmission for vehicle
A transmission for a vehicle includes a knob configured to be rotated to select one of a plurality of shift stages, a driving unit for controlling rotation of the knob, and a shift controller for applying an electrical current to generate a torque in the driving unit. Further, the driving unit includes a magnetic field generator, a magnetization unit including a plurality of magnetic bodies arranged at regular intervals along a circumference of the magnetic field generator, and a magnet unit including at least one pair of magnetic poles arranged along a circumference of the magnetization unit. In particular, the magnetization unit or the magnet unit is coupled with the knob and rotates integrally with the knob. Depending on an intensity of a magnetic field generated by the magnetic field generator, the driving unit allows or prevents the rotation of the knob.
Rattle reduction device for dial type shifting apparatus
A rattle reduction device for a dial type shifting apparatus is provided and includes a damper provided to be fixed to a main housing, and a protrusion formed on a component configured to rotate with respect to the main housing and configured to reduce a return rotation speed of a shift dial by contacting the damper when the shift dial returns from a position of a Nd stage or a D stage to a Null stage or returns from a position of a Nr stage or a R stage to the Null stage, thereby reducing rattle.
ELECTRONIC SHIFT CONTROL APPARATUS
An electronic shift control apparatus may include a shift dial that a user operates to select an R-range, an N-range (Nd-range and Nr-range), and a D-range, a P-range button which is operated to select a P-range, and a haptic motor that generates a haptic signal. When a driver shifts into a specific shifting range (R-range) of a vehicle by operating the shift dial, a haptic signal may be transmitted to the driver.
Electronic shift system for an automated manual transmission
An electronic shift system for an automated manual transmission includes a shift lever moveable between at least a neutral position and a first gear position, a clutch pedal, a biasing member connected to the shift lever that biases the shift lever to the neutral position, and a grip system configured to selectively immobilize the shift lever in the first gear position when the clutch pedal is released. An electrical circuit communicates a position of the shift lever to a control module. The control module commands the automated manual transmission to achieve the gear ratio (forward or reverse) corresponding to the first gear position when the shift lever is in the first gear position.
AUTOMATIC TRANSMISSION SHIFTER WITH SPEED SENSITIVE DAMPING
A shifter assembly includes a shift lever, a base, a coupling member having a toothed member and pivotably coupling the shift lever to the base, and a speed sensitive damping arrangement housed in the base. The damping arrangement includes a housing associated with the base and defining an internal cavity, a shaft disposed in the cavity and having an end extending from the housing, and a gear coupled to the shaft end extending from the housing and configured for rotation therewith, where the gear is meshingly engaged with the toothed member of the coupling member such that pivotable movement of the coupling member rotates the gear and the shaft. The gear is configured to rotate faster than the shift lever such that damping to movement of the shift lever provided by the damping arrangement is proportional to a square of a speed of movement of the shift lever.
ELECTRONIC TRANSMISSION RANGE SELECTION SYSTEM INCLUDING A BEZEL WITH LOCATING FEATURES
A transmission shifter assembly includes a shifter and a shifter bezel. The shifter includes a shifter body and a shifter handle movably coupled to the shifter body. The shifter bezel includes a bezel body and defines a handle opening extending through the bezel body. The handle opening is sized to partially receive the shifter handle. The shifter handle extends through the handle opening. The transmission shifter assembly further includes a plurality of locating features, such as shock absorbers, interconnecting the shifter bezel and the shifter body in order to align the shifter bezel relative to the shifter.
Shift device
In a shift device, as a result of lower sliding projections of a lever moving slidingly against lower sliding plates of soft materials, the slidability of the lever is improved. Moreover, as a result of restricting projections of the lever being abutted against stoppers of the soft materials, noise generated when a sliding motion of the lever is restricted is reduced. Additionally, because the lower sliding plates and the stoppers are formed integrally with each other, the structure can be simplified.
Dial-type shifting control apparatus for vehicles
A dial-type shifting control apparatus of vehicles may include a dial bezel and an upper cover integrated into a single body to be rotated together when a dial is rotated, obviating formation of an operation gap between the dial bezel and the upper cover to prevent foreign substances from entering through the operation gap, and a button guide disposed under an upper cover attenuates an impact occurring when a P-gear button is returned, and thus to prevent noise, caused by striking of the upper cover when the P-gear button is returned, from being transmitted to the interior of a vehicle.
Gear shift linkage mechanism and gear shift apparatus
A gear shift linkage mechanism includes a gear shift linkage assembly and a spherical bowl for connecting to a gear shift rocker arm. The gear shift linkage assembly includes a connecting member, a gear shift linkage, a first elastic element, and a second elastic element. One end of the connecting member is connected with the spherical bowl, one end of the gear shift linkage is movably configured in the cavity. One end of the first elastic element presses against the limiting portion, and another end of the first elastic element is supported on the cavity. One end of the second elastic element presses against the limiting portion, and another end of the second elastic element is supported on the first through hole. The gear shift linkage mechanism efficiently improves the buffering and damping effect of the gear shift linkage assembly, and thus prevents damage of the transmission.
Electronic shift control apparatus
An electronic shift control apparatus may include a shift dial that a user operates to select an R-range, an N-range (Nd-range and Nr-range), and a D-range, a P-range button which is operated to select a P-range, and a haptic motor that generates a haptic signal. When a driver shifts into a specific shifting range (R-range) of a vehicle by operating the shift dial, a haptic signal may be transmitted to the driver.
