Definitions
- the invention relates to a parking lock for automatic transmissions of motor vehicles, in which the
- Output of the transmission is blocked by a pawl engages a parking lock wheel and this is thus secured against rotation.
- DE 43 17 257 describes a parking lock for automatic transmissions of motor vehicles, in which a pawl is pulled out of the parking lock wheel by filling a cylinder with pressure oil and its piston, against a spring force, moves a connecting rod over a link piece.
- a hand lever By manually moving a hand lever via an active connection, the connecting rod with the pawl in the scenery piece can be moved, locked and thus the parking lock can be unlocked.
- the piston rod has a direct connection to the connecting rod of the pawl via the linearly moving link piece and thus a linear movement is transmitted directly to the connecting rod, the operative connection, which therefore also carries out a linear movement, must be carried out since it ends in the passenger compartment of the vehicle , are sealed in the automatic transmission.
- the parking lock If the parking lock is to be released hydraulically, the pawl is pulled out of the parking lock wheel by the connecting rod executing a linear movement, which is pulled back by a bolt which is guided in an obliquely running groove in the scenery piece. As a result, considerable frictional forces occur between the bolt and the obliquely running groove. If the parking lock is released manually and the bolt engages in the scenery piece, this position can be unlatched again by applying pressure to the piston of the hydraulic unit and the bolt being able to leave the latching position. In this state, there is the possibility that the bolt hits the fork of the grooves in the scenery piece and is sheared off in the process. By using a backdrop Stuckes there is also the possibility that driving poking cause an unintended operation of the parking brake device, since a linearly mounted link stucco is a spring-mass system which responds to te linear Strengthens ⁇ .
- the present invention has for its object to provide a parking lock for automatic transmissions of motor vehicles, which is characterized by high functional reliability, simple structure, reliable sealing and low friction.
- the parking lock consists of a device which is connected to a connecting rod with a pawl and is moved by a hydraulic actuating device consisting of a piston, a cylinder and a return spring.
- the device consists of two disks, which are arranged on a common shaft, and functions of the parking lock can be actuated by rotating the disks.
- a first washer here called a detent washer, has a first, off-center connection to a connecting rod with a pawl and a second, off-center connection opposite the first connection to a hydraulic actuation device. If the hydraulic actuation device is actuated, the parking lock is locked or unlocked exclusively by rotating the device.
- a second disk here called emergency release disk
- the emergency release disk can be rotated within two stops and is automatically locked in a position in which the parking lock is unlocked by means of a detent, preferably a spring, by means of the emergency release and thus the turning of the emergency release disk and the pin by the rotation of the detent disk held in this position until this position is turned back to the initial state by rotating the first disc by automatically unlocking the catch.
- a detent preferably a spring
- 1 shows a parking lock, in which the parking lock wheel is blocked by the parking pawl
- Fig. 3 shows a parking lock, which has been hydraulically unlocked so that the parking pawl releases the parking lock wheel
- Fig. 4 is a parking lock of the type described above in the sectional view.
- a parking lock which consists of a device 1, an actuating device 7, a manual actuating device 13 and a lock 17, is located within a transmission housing 11 of an automatic transmission. If no system pressure is generated by the automatic transmission, the actuating device 7 is depressurized and the piston 6 is moved via the spring 9 until it stops in the cylinder 8 or the recess 5 stops on the pin 4.
- the piston 6 is connected via a connection 18 via a locking disk 2 via a connection 19 to the Lock 17 connected, which consists of a cone and a parking pawl 16 and a parking lock ⁇ wheel, not shown.
- the locking disk 2 is rotated about its central axis 20 via the connection 18 and moves the connection 19 with the aid of the spring force of the spring 9, so that the parking pawl is in the locking 17 16 engages in the parking lock wheel and blocks the parking lock wheel.
- the locking disk 2 has a recess 5, in which the pin 4, which is fastened on the emergency release disk 3, is located.
- the emergency release disk 3 is printed with the stop 10 on the gear housing 11 via the spring force of the spring 12. The force of the manual actuation device and the spring 12 is applied to the emergency release disk 3 via the shaft 21.
- the manual actuation device is connected to the emergency release disk 3 via a cam. Since the stop 10 of the emergency release disk 3 is in contact with the housing 11, the detent disk 2 is rotated until the recess 5 is in contact with the pin 4 or the piston 6 in the cylinder 8.
- the parking lock unlocks and the catch 14 engages in the emergency release disk 3 after the elevation 22.
- the vehicle can be towed in this position.
- Fig. 3 shows a position of the parking lock, which unlocks the parking lock by applying a hydraulic force.
- a hydraulic pressure is given in the cylinder 8 of the actuation device 7. This acts on the piston 6 and moves the piston and the connection 18.
- the locking disk 2 is rotated and the cam 15 lifts the detent 14, so that the emergency release disk 3 can slide under the detent 14 with the elevation 22 until the Stop 10 on housing 11 comes to rest.
- the emergency release disk 3 and the manual actuation device 13 are thus turned back to their original state via the spring force of the spring 12 m.
- the connection 19 is moved by rotating the locking disk 2, so that the locking 17 is unlocked against the spring force 9.
- the detent 14 of the emergency release device is automatically reset by applying a hydraulic pressure to the actuating device 7.
- the detent spring can have a roller at its free end, which enables the detent to be more easily disengaged from the cam 15.
- FIG. 4 shows a section through the device, which shows in particular the simple attachment of the manual actuating device 13 to the emergency unlocking disk 3 via the shaft 21.
- This structural design provides a simple and reliable sealing of the unlocking device 1.
- the shaft 21 and thus the locking disk 2 and the emergency release disk 3 can rotate about the central axis 20 and are mounted in the housing 11.
- the emergency release disk 3 is preferably connected to the shaft 21 via a pin connection.
- the locking disk 2 is rotatably mounted on the shaft 21.
