Abstract:
A lever device (100) includes: a bracket (18) fixed to a vehicle; a lever (12) pivotally held by the bracket (18) and pivoted to apply tension to a wire (19) connected to brake units (22, 23) of wheels, thereby applying a brake to the wheels; a pole lever (14) engaged with one of teeth (15) formed in the bracket (18) to keep the lever (14) at a selected pivot angle and pivotally held by the lever (12); a release rod (13) connected to the pole lever (14),- and a switch (11) that pushes the release rod (13) to disengage the pole lever (14) from the tooth (15). The interval between part of the teeth (15), with which the pole lever (14) is engaged when the lever (12) is at a first pivot angle, is wider than the interval between another part of the teeth (15), with which the pole lever (14) is engaged when the lever (12) is at a second pivot angle that is larger than the first pivot angle.
Abstract:
A parking brake assembly for a vehicle has a mounting bracket, a handle assembly and a clutching mechanism. The mounting bracket has a stop. The handle assembly is pivotally mounted on the mounting bracket for rotation about a first axis. The handle is moveable between a brake applied position and a brake release position. The handle has an actuator. A cam is pivotally mounted on the handle about a second axis offset from the first axis. The cam has a cam surface which varies radially from the second axis. The cam is biased to engage the stop. A clutch spring frictionally engages the cam and is operably connected to the actuator. Movement of the actuator in response to manual manipulation responsively moves the clutch spring to decrease the frictional engagement, thereby enabling the cam to engage with the stop. In response to releasing the actuator, the clutch spring moves to increase frictional engagement with the cam thereby retaining the cam in a position to engage the stop and prop the handle in a braking position.
Abstract:
The present invention relates to a parking brake including a lever (3) coupled to a brake wire (9) included in the brake system. Characteristic of the invention is that the lever (3) is arranged to work in two steps to achieve the desired braking power. In the first step the lever is arranged to make a translational movement for taking up wire slack in the brake system, while in the second step the lever is arranged to execute a rotation whereby the force transmission to the wire (9) takes place at a higher ratio than in the first step.
Abstract:
Die Erfindung betrifft eine Betätigungsvorrichtung (1) für eine Feststellbremse und umfasst einen an einem Lagerbock (3) schwenkbar gelagerten Handbremshebel (2), sowie eine Festsetzeinrichtung, mittels derer der Handbremshebel (2) in einer Schwenkstellung am Lagerbock (3) fixierbar ist. Die Festsetzeinrichtung weist ein mit dem Lagerbock (3) verbundenes Sperrsegment (11) und eine am Handbremshebel (2) gelagerte Sperrklinke (12) auf. Der Lagerbock (3) und das Sperrsegment (11) sind einteilig ausgebildet und von einem Druckgussteil oder Spritzgussteil gebildet.
Abstract:
Die Erfindung betrifft eine Bedienvorrichtung für ein Fahrzeug mit automatisiertem Getriebe und einem elektrisch betätigten Parkbremssystem, bestehend aus mindestens einem mechanischen Betätigungselement zur Eingabe von Bedienbefehlen des Fahrzeugnutzers und einer Steuerungseinheit zur Umsetzung der Bedienbefehle in Steuersignale an das Getriebe und das Parkbremssystem, bei dem erfindungsgemäß das Betätigungselement (1) mindestens zwei aufeinander folgende Raststellungen (B, C) sowie eine Neutralposition (A) und eine Rückstellposition (D) aufweist, wobei in der ersten Raststellung (B) ein Bedienbefehl an das Parkbremssystem (4) zur Betätigung der Parkbremsvorrichtung und in der zweiten Raststellung (C) ein Bedienbefehl an das Getriebe zur Betätigung der Parksperrvorrichtung generiert wird. Die spezielle Ausgestaltung der Betätigungselementes vereint zwei bislang unterschiedliche und in aller Regel auch innerhalb des Fahrzeuges räumlich getrennte Betätigungselemente in einer gemeinsamen Bedienvorrichtung, so dass dem Fahrzeugnutzer nunmehr problemlos und intuitiv die Wahl bleibt, ob er neben der üblichen Betätigung des elektrisch betätigten Parkbremssystems zusätzlich die dem automatisierten/oder Automatikgetriebe zugeordnete Parksperrvorrichtung einlegen möchte.
Abstract:
The present invention pertains to a device for actuating brakes on a vehicle or something similar by means of a brake lever (1) mounted pivotly on a fixed maintaining member (5) in the vehicle. Furthermore, a brake pull bar (7) is, at one end, operatively linked with the brake lever and intended to actuate the vehicle brakes using said lever (1). There is a transmission (7), including a gear drive, between the brake lever (1) and the brake pull bar (7).
Abstract:
The disclosed mechanism incorporates a self-regulating device and a self-adjusting device. The self-regulating device comprises a traction body (36) connected at one end (44) of the steel control cable (60) and a traction spring (37) which are coupled to the rotation axis (5) of the brake lever (4), and a pushing element (47) coupled to the rotation axis (8) of the lever (7) of the ratchet (6), both bodies (36, 47) having a respective toothing (41, 52) of mutual meshing so that, when the brake lever (4) is in the rest position, the spring (37) subjects to traction said extremity (44) whereby the length of the sheathed portion of the control cable is permanently adjusted. The self adjusting device comprises, in the traction body (36) and in the support (2) of the mechanism, a corresponding orifice (42, 58) which receives an anchoring pin (59). Application to the car industry.
Abstract:
An electric motor-driven parking brake of a motor vehicle can be released in an emergency by applying emergency current from a parallel emergency current source to the motors controlling the parking brake. The direction of the emergency current is selected to reverse the motors, i.e., release the parking brake.
