Definitions
- the present invention relates to a parking brake assembly, and more particularly to a parking brake assembly that includes a self-adjust mechanism.
- a parking brake for a vehicle is typically actuated by a cable that is connected to a hand- or foot-operated lever mounted in the vehicle's cabin. Over time, with repeated actuations the cable can stretch, however. With some parking brake assembly designs, when a cable became stretched there would be an initial amount of lever travel that would simply take up the slack in the cable without actuating the brake. As a result, as the cable stretches over time, a progressively greater amount of lever travel would be required to actuate the brake.
- Some parking brakes have been proposed which include a self- adjust mechanism so that even after the cable stretches the system eliminates the slack in the cable. As a result, the same amount of lever travel is required regardless of whether the cable has stretched over time.
- Such self-adjust mechanisms typically involve many components, which can augment the cost of the parking brake assembly, and which can add to the size of the assembly. It would be advantageous to provide a parking brake assembly with a self-adjust mechanism that involves relatively fewer components and/or at a relatively lower cost.
- the invention is directed to a parking brake assembly with a self-adjust mechanism that uses a single spring to tension a parking brake cable and to bias first and second locking members towards locking the parking brake cable for movement with a parking brake lever during movement of the parking brake lever towards a brake actuation position.
- the parking brake assembly includes a first ratchet member that is connectable to the parking brake cable, a second ratchet member, a parking brake lever operatively connected to the second ratchet member, and a spring that is positioned to urge the first and second ratchet members in opposite directions and is positioned to bias the second ratchet member towards locking the first ratchet member for movement with the parking brake lever towards a brake actuation position.
- the parking brake assembly includes a parking brake lever, a first locking member that is connectable to the parking brake cable, a second locking member and a spring.
- the parking brake lever is operatively connected to the second locking member for movement between a locking position wherein the second locking member engages the first locking member and locks the first locking member for movement with the parking brake lever in a first direction, and an unlocking position wherein the second locking member unlocks the first locking member from the parking brake lever during movement of the parking brake lever in the first direction.
- the spring is positioned to apply a tensioning force to the parking brake cable and is positioned to bias the second locking member towards the locking position.
- the parking brake assembly includes a parking brake lever that is movable between a home position and a brake actuation position, a lock housing movable by the parking brake lever, a first locking member that is connectable to the parking brake cable, a second locking member that is movable relative to the lock housing between a locking position wherein the second locking member engages the first locking member and locks the first locking member for movement with the lock housing in a first direction, and an unlocking position wherein the second locking member unlocks the first locking member from the lock housing during movement of the lock housing in the first direction, and a spring that is positioned to apply a tensioning force to the parking brake cable and is positioned to bias the second locking member towards the locking position.
- the lock housing is movable by the parking brake lever between a home position, a parking brake cable locking position, and a brake actuation position.
- the second locking member In the home position the second locking member is in the unlocking position, the spring is positioned to exert a tensioning force on the parking brake cable and the first locking member is positioned for non-actuation of the parking brake.
- the parking brake cable locking position In the parking brake cable locking position the second locking member is in the locking position and the first locking member is positioned for non-actuation of the parking brake.

- FIG. 1 shows parking brake assembly 10 for controlling a parking brake cable (not shown) for a vehicular parking brake (not shown), in accordance with an embodiment of the present invention.
- the parking brake assembly 10 includes a parking brake lever 12, a lock housing 14, a first locking member 16, a spring 18 and a second locking member 20.
- the parking brake lever 12 is mounted for rotation about a parking brake lever axis Apbl.
- the parking brake lever 12 is shown as being a hand-operated lever, however it is alternatively possible for the parking brake lever to be a foot-operated lever.
- the parking brake lever 12 is movable between a home position shown in Figures 1 and 1a and a brake actuation position shown in Figures 3 and 3a.
- the brake actuation position may be any position over a range depending on the amount of force with which a vehicle occupant operates the parking brake lever 12.
- the parking brake lever 12 may include a ratchet mechanism to hold it at a given brake actuation position, and may be biased towards the position shown in Figures 1 and 1a.
- the lock housing 14 is rotatably mounted to the parking brake lever 12, about an axis Ash.
- the lock housing 14 is movable by the parking brake lever 12 in a first direction 22 and in a second direction 24. The movement of the lock housing 14 is discussed further below.
- the first locking member 16 has a first end 26 and a second end
- the first end 26 is connectable to the parking brake cable (not shown).
- the second end 28 is engaged with the spring 18.
- the first locking member 16 has thereon a first set of teeth 32 which are described further below.
- the second locking member 20 is movable along a wedging surface 34 of the lock housing 14, between a locking position ( Figure 2) and an unlocking position ( Figures 1 and 1a). In the locking position the second locking member 20 engages the first locking member 16 and locks the first locking member 16 (and therefore the parking brake cable) to the lock housing 14 (and therefore the parking brake lever for movement in the first direction 22, which is towards the brake actuation position.
- the second locking member 20 when the second locking member 20 is in the locking position, the first locking member 16 and the associated parking brake cable are locked for movement with the lock housing and the parking brake lever 12 in the first direction 22 towards the brake actuation position. In this way, movement of the lock housing 14 in the first direction 22 actuates the parking brake.
- the second locking member 20 In the unlocking position ( Figures 1 and 1a) the second locking member 20 permits movement of the first locking member 16 relative to the lock housing 14 in both the first and second directions 22 and 24. Therefore, when the second locking member 20 is in the unlocking position, the spring 18 acts on the first locking member 16 to tension the parking brake cable.
- the engagement of the second locking member 20 with the first locking member 16 when the second locking member 20 is in the locking position may be any suitable type of engagement.
- the second locking member 20 may have thereon a second set of teeth 36 for engaging the first set of teeth 34 on the first locking member 16.
- the first and second locking members 16 and 20 may be referred to as first and second ratchet members.
- the second locking member 20 has a spring engagement shoulder 42 that is positioned to engage the spring 18.
- the second locking member 20 further includes an unlocking member engagement surface 44 that is configured to engage an unlocking member 46, at a selected point along the travel of the lock housing 14.
- the unlocking member 46 is mounted on a stationary structure of the vehicle, shown at 48.
- the spring 18 has a first end 50 that is engaged with the second end 28 of the first locking member 16.
- the spring 18 has a second end 52 that is engaged with the spring engagement shoulder 42.
- the spring 18 thus is positioned to apply a tensioning force to the parking brake cable (not shown), though the first locking member 16. Additionally, the spring 18 is positioned to bias the second locking member 20 along the wedging surface 34 towards the locking position ( Figure 2).
- the spring 18 urges the first and second locking members 16 and 20 in opposite directions.
- the spring 18 may be any suitable type of spring, such as, for example, a compression spring.
- the lock housing 14 is movable by the parking brake lever 12 between a home position, shown in Figures 1 and 1a, a parking brake cable locking position shown in Figure 2 and a brake actuation position shown in Figures 3 and 3a.
- the home position Figures 1 and 1a
- the second locking member 20 In the home position ( Figures 1 and 1a), the second locking member 20 is in the unlocking position and the first locking member is positioned for non-actuation of the parking brake.
- the parking brake cable locking position Figure 2
- the second locking member 20 is in the locking position and the first locking member 16 is positioned for non-actuation of the parking brake is not actuated.
- the brake actuation position Figures 3 and 3a
- the second locking member 20 is in the locking position and the first locking member 16 is positioned for actuation of the parking brake.
- the spring 18 is under some compression, thereby maintaining a tensile force on the first locking member 16 and therefore on the parking brake cable (not shown). Also, the spring 18 urges the second locking member 20 towards its locking position ( Figures 3 and 3a), however, the second locking member 20 is prevented from moving to its locking position because of its engagement with the unlocking member 46.
- the second locking member 20 rides along the wedging surface 34 to its locking position, shown in Figure 2, under the urging of the spring 18, where it engages the first locking member 16, by meshing of the first teeth 32 and second teeth 36.
- the wedging surface 34 cooperates with an opposing surface 53 to wedge the engaged first and second locking members 16 and 20 thereby locking the first locking member 16 and the parking brake cable with the lock housing 14 for movement in the first direction 22 towards the brake actuation position.
- Further movement of the lock housing 40 to a brake actuation position ( Figures 3 and 3a) by the parking brake lever 12 moves the first locking member 30 and the parking brake cable (not shown) to actuate the parking brake (not shown).
- the vehicle occupant may push an optional release button shown at 54 ( Figure 3) on the parking brake lever 12, which disengages the optional ratchet mechanism therein (not shown).
- the parking brake lever 12 may then be moved from its brake actuation position ( Figures 3 and 3a) towards its home position shown in Figures 1 and 1a.
- This movement of the parking brake lever 12 moves the lock housing 14 in the second direction 24 from its brake actuation position ( Figures 3 and 3a) towards its home position ( Figures 1 and 1a).
- the parking brake (not shown) become unactuated.
- the parking brake cable (not shown) may stretch.
- the spring 18 may be in a more relaxed state than before the parking brake cable became stretched.
- the spring 18 will remain somewhat flexed, (ie. compressed somewhat in the embodiment shown in the figures), and will thus maintain tension in the stretched parking brake cable, and maintain a biasing force on the second locking member 20 urging the second locking member 20 towards the locking position shown in Figure 2.
- a shipping pin 56 may be inserted through a shipping pin receiving aperture 58 in the lock housing 14.
- the shipping pin receiving aperture 58 may pass- through the entire lock housing so that the shipping pin 56 extends out of the lock housing 14 on both sides.
- the shipping pin receiving aperture 58 is positioned so that when the shipping pin 56 passes therethrough, it holds the spring 18 ( Figure 5) in a compressed state wherein the second locking member 20 may be in the locking position, which holds it with the rest of the parking brake assembly 10, thereby preventing the second locking member 20 from becoming separated from the rest of the parking brake assembly 10 during shipping.
- the compression of the spring 18 by the shipping pin 56 causes the first locking member 16 to extend outwards from the lock housing 14. This facilitates the attachment of the parking brake cable (not shown) to the parking brake assembly 10 during installation into a vehicle.
- FIG. 6 shows a parking brake assembly 70 in accordance with another embodiment of the present invention.
- the parking brake assembly 70 includes a parking brake lever 72, a first locking member 74, a second locking member 76 and a spring 78.
- the parking brake lever 72 may be similar to the parking brake lever 12 ( Figure 1) but instead of connecting to the spring housing 14 ( Figure 1), the parking brake lever 72 connects to an optional pivoting link 80, which in turn pivotably connects to the second locking member 76 for rotation about a pivot axis AsIm.
- the first locking member 74 may be similar to the first locking member 16 and includes a first set of teeth 82.
- the second locking member 76 includes a pass-through aperture 84 which permits the pass-through of the first locking member 74.
- a first surface 86 which includes a second set of teeth 88 thereon, which are engageable with the first set of teeth 82 on the first locking member 74.
- the first surface 86 further includes a slide surface 90, which is configured to permit sliding movement of the first locking member 74 thereon.
- the second locking member 76 further includes an unlocking member engagement surface 92 that is engageable with an unlocking member 94 mounted to a stationary part of the vehicle.
- the spring 78 is positioned between the first locking member 74 and the second locking member 76 and urges them in opposite directions so that the first locking member 74 is in tension. Additionally, the spring 78 urges the second locking member 76 towards a locking position shown in Figure 7b, in which the second set of teeth 88 engage the first set of teeth 82 thereby locking the first locking member 74 for movement with the second locking member in the first direction shown at 96 ( Figure 6). Thus, the engagement of the first and second sets of teeth 82 and 88 locks the first locking member 74 for movement with the parking brake lever 72 towards the brake actuation position.
- the unlocking member engagement surface 92 engages the unlocking member 94, which causes the second locking member 76 to pivot (counterclockwise in the view shown in Figures 7a and 7b) to an unlocking position shown in Figure 7a.
- the second set of teeth 88 on the second locking member 76 are disengaged from a first set of teeth 82 on the first locking member 74.
- the slide surface 90 engages the first set of teeth 82 which permits the first locking member 74 to slide relative to the second locking member 76, which permits the first locking member 74 to be in tension under the urging of the spring 78.
- first direction 96 ( Figure 6) need not be in any particular direction, except that it is a direction that cause the brake cable (not shown) to be pulled and thereby actuated.
