Embodiment Construction

[0027] figure 1 is a schematic view showing a powertrain 1 for a vehicle.

[0028] The transmission system has an input shaft 2 and an output shaft 3 . The input shaft 2 and the output shaft 3 are connected to each other through a gear 4 . For example, the first gear 5 of the input shaft 2 is engaged with the first gear 6 of the output shaft 3 , and the second gear 7 of the input shaft 2 is engaged with the second gear 8 of the output shaft 3 . The gears 6 , 8 of the output shaft 3 may be idler gears, ie these gears 6 , 8 are mounted on the output shaft 3 by bearings, but are rotatably locked to the output shaft by a synchronizer 9 . By movement of the synchronizer sleeve 10 in the first direction, the first gear wheel 6 of the output shaft 3 is rotationally locked to the output shaft 3 . The second gear wheel 8 of the output shaft 3 is rotationally locked to the output shaft 3 by movement of the synchronizer sleeve 10 in a second, opposite direction. Thus, one gear is rep...

Abstract

The invention relates to a parking lock device (16) for a transmission of a vehicle. The device comprising a wheel (17), a pawl (18) for locking the wheel against rotation and an actuator unit (20) arranged for movement of the pawl relative to the wheel. The pawl (18) has a locked position where the pawl and the wheel are engaged and an unlocked position where the pawl and the wheel are disengaged. The pawl (18) and the actuator unit (20) are mechanically coupled to each other by a pin and slot mechanism (21) having a guide slot (22) and a guide pin (23) received by the guide slot. The device is less complicated and enables a simplified production and assembling of the parking lock mechanism.

Description

technical field [0001] The invention relates to a parking lock device for a drive train of a vehicle, the device comprising a wheel, a pawl for locking the wheel against rotation thereof, and an actuator unit arranged for moving the pawl relative to the wheel . The invention also relates to a transmission system comprising such a parking lock device. Background technique [0002] Vehicle drivelines typically have a park lock mechanism with an actuation linkage for the engagement of a ratchet and pawl to lock the axle of the driveline. [0003] This parking lock mechanism requires several close tolerance components such as the actuation lever, cone and cone interface, and spring. Due to the tolerance chain of the critical components, high demands are placed on the production. Furthermore, the assembly process is also relatively complex, and since the installation space in drive trains is often very limited, it is desirable to reduce the number of components.
