Abstract
Methods and systems are provided for operating a solenoid actuator to engage and/or disengage a torque transmission member of a vehicle transmission. In one example, a method may include increasing the holding force of the solenoid actuator. Additionally, the solenoid actuator may include a translatable structural element that creates a moment upon touching another structural element holding the translatable element in a locked position.
Claims20
A method, comprising:
- operating a solenoid actuator to engage and/or disengage a torque transmission member of a vehicle transmission, the solenoid actuator including a translatable structural element to effect the engagement and/or disengagement, where the translatable structural element is linearly moved until it touches a surface that creates a moment that tilts the structural element to lock the structural element in place.
A solenoid actuator, comprising:
- a housing;
- a coil positioned in the housing;
- a plunger positioned in the housing, wherein the plunger includes a contact region. The plunger configured to tilt upon the contact region contacting a portion of a structure fixed with the housing.
A method, comprising:
- increasing current to a solenoid actuator to engage a torque transmission member of a vehicle transmission, including:
- first linearly translating a translatable structural element against a spring, and
- second, after initial linear translation, tilting the translatable structural element to lock the translatable structural element in place;
- and
- reduce the current while friction maintains the translatable structural element to maintain engagement of the torque transmission member.
