发明名称 Mechanism for vehicle transmission default to park
摘要 A default-to-park mechanism for a transmission includes an output member, a rotatable plate, a latching mechanism, and a biasing member. The output member is rotatable to park, reverse, neutral, and drive positions. The rotatable plate is coaxial with the output member. The plate and the output member interfere with one another such that the plate is moved in a first direction of rotation by the output member and the output member is moved in a second direction of rotation by the plate. The plate is releasably held by the latching mechanism to prevent rotation in the second direction of rotation when the output member is in the reverse, neutral, and drive positions. The biasing member biases the plate to rotate in the second direction of rotation to return the output member to the park position when the plate is released by the latching mechanism.

主权项 1. A mechanism for a transmission having a park mode and multiple additional modes, the mechanism comprising: an output member operatively connectable to the transmission and rotatable to predetermined positions including a park position correlated with the park mode and multiple additional positions correlated with the multiple additional modes, respectively; a rotatable plate coaxial with the output member; wherein the plate and the output member are configured to interfere with one another such that the plate is moved in a first direction of rotation by the output member when the output member is rotated in the first direction of rotation, and the output member is moved in a second direction of rotation by the plate when the plate moves in the second direction of rotation; wherein the second direction of rotation is opposite from the first direction of rotation; a latching mechanism; wherein the plate is configured to be releasably held by the latching mechanism to prevent rotation in the second direction of rotation when the output member is in any one of the multiple additional positions; and a first biasing member biasing the plate to rotate in the second direction of rotation to return the output member to the park position when the plate is released by the latching mechanism.
