초록 ▼

An electromechanical parking brake system is provided including an electric driving gear motor connected with a parking brake cable track member by a releasable connection, preferably in the form of a pawl and ratchet arrangement. In accordance with one feature of the invention, a manually-operable override device is provided for disengaging the pawl from the ratchet, thereby to disconnect the electric drive motor. According to another feature, the pawl is automatically disengaged from the ratchet when the cable track member is in the brake-released condition, so that a cable-tensioning device is actuated to remove slack from the parking brake cable.

대표청구항 ▼

Parking brake apparatus for operating the parking brake cable of a vehicle between non-tensioned brake-released and tensioned brake-engaged condition, respectively, comprising: (a) a housing (2) provided with a stationary main pivot shaft (4); (b) an annular cable track member (10) journalled on said pivot shaft, said cable track member being adapted for connection with one end of the parking brake cable; (c) drive means for alternately rotating said cable track member in opposite directions on said pivot shaft toward brake-engaged and brake-released positions relative to said housing, respectively, said drive means including: (1) a gear sector member (6) rotatably mounted on said pivot shaft; (2) reversible electric gear motor means (18) connected with said housing and including an output shaft having a driving pinion (20) in enmeshing engagement with said gear sector member; (3) pawl ratchet means normally connecting said gear sector member with said cable track member, said pawl and ratchet means including: (a) a ratchet (8) connected with one of said cable track and sector members; (b) a pawl (28) pivotally connected with the other of said members; and (c) spring means (30) normally biasing said pawl toward engagement with said ratchet; and (4) means (58) for alternately operating said motor means in opposite directions, respectively; and (d) means (34,62) for releasing said pawl from said ratchet, thereby to disconnect said cable track member from said drive means.
