Problems solved by technology

If the damper is active regardless of the driving conditions, it will also prevent the clutch from re-engaging quickly when shifting between any gears, which would be uncomfortable for the driver
Furthermore, if the damper is only active when the vehicle is launched from a standstill, the clutch will exhibit inconsistent re-engagement behavior depending on driving conditions, which may confuse the driver

Embodiment Construction

[0028] figure 1 Shown is the driver-operated clutch pedal 1 pivoted about 2 and biased by return spring 3 to figure 1 The position shown on the left corresponds to the engaged state of the clutch of a manually shifted motor vehicle transmission. The clutch is separated by stepping on the pedal 1. exist figure 1 On the right side of , it shows that the clutch pedal 1 is depressed.

[0029] The clutch pedal 1 can be connected by any mechanical and / or hydraulic linkage to a push rod located near the clutch, which push rod can act on the clutch pressure plate.

[0030] exist figure 1 In , a damper 4 is provided and adapted to delay clutch engagement in quick release of the clutch pedal 1 . The damper 4 comprises a cylinder 5 , a piston 6 , a piston rod 7 and a relatively weak return spring 8 for the piston 6 and piston rod 7 .

[0031] Piston rod 7 has free end 9, and this free end 9 has when clutch pedal 1 such as figure 1 The actuating surface shown on the left abuts agai...

Abstract

The invention relates to a clutch actuator for a manual-shift motor vehicle transmission, comprising a driver-operated clutch pedal (1) or lever, a clutch linkage between a clutch of the motor vehicle and the pedal (1) or lever, and a damper (4) adapted to delay clutch engagement on a fast release of the clutch pedal or lever. According to the invention, the damper (4) is effective to delay clutch engagement only within a limited range of a whole clutch engagement movement and is substantially ineffective outside the limited range and within the whole range of a clutch disengagement movement.

Description

technical field [0001] The invention relates to a clutch actuator for a manually shifted motor vehicle transmission according to the preamble of claim 1, comprising a clutch pedal or lever operated by the driver, a clutch between the clutch of the motor vehicle and the pedal or lever A clutch linkage, and a damper adapted to delay clutch engagement upon quick release of the clutch pedal or lever. Background technique [0002] Such a clutch actuator is disclosed in US 2014 / 0110217 A1. A damper permanently attached to the pedal or lever or to a portion of the clutch linkage delays excessive engagement of the clutch by providing a force opposing the pressure from the clutch pedal or lever return spring. Dampers serve the function of preventing damage to the motor vehicle and avoiding discomfort to the occupants. The damper is more effective during the clutch engagement movement than during the clutch disengagement movement, and the damper may only be effective when the vehicl...
