Embodiment 1
[0017] Example 1, such as Figure 1-3 It can be seen from the shown structure that a clutch pedal assembly of the present invention is an assembly of a clutch pedal mechanism with double power assistance, including a pedal bracket 1, a pedal arm 3 is installed on the pedal bracket 1 through the pedal arm rotation shaft 2, and the end of the pedal arm 3 is A pedal pad 4 is fixed. The booster spring mechanism arranged between the pedal arm 3 and the pedal bracket 1 includes an upper booster spring mechanism and a lower booster spring mechanism, wherein the upper booster spring mechanism is arranged above the pedal arm rotation shaft 2, and the lower booster spring mechanism is arranged on the pedal arm Below the axis of rotation 2. The upper booster spring mechanism includes an upper spring guide rod 5 connected with the pedal bracket 1, and an upper spring guide sleeve 6 connected with the pedal arm 3, and an upper booster spring is installed between the upper spring guide rod...

The invention discloses a clutch pedal assembly which comprises a pedal bracket, a pedal arm and a booster spring mechanism, wherein the pedal arm is hinged on the pedal bracket through a rotating shaft of the pedal arm, and a pedal pad is arranged at the tail end of the pedal arm; the booster spring mechanism is divided into an upper booster spring mechanism and a lower booster spring mechanism; the upper booster spring mechanism is arranged at the upper side of the pedal bracket and comprises an upper spring guide rod articulated with the bottom end of the pedal bracket, an upper spring guide sleeve articulated with the top end of the pedal arm and an upper booster spring arranged between the upper spring guide rod and the upper spring guide sleeve; and the lower booster spring mechanism is arranged at the lower side of the pedal bracket and comprises a lower spring sleeve articulated with a connecting bracket of the upper spring guide sleeve, a lower spring guide rod articulated with the pedal arm and a lower booster spring arranged between the lower spring guide sleeve and the lower spring guide rod. The clutch pedal assembly of a double booster spring mechanism remarkably reduces the clutch pedal force on the premise of ensuring appropriate pedal stroke and appropriate maximum pedal return force, improves the operation comfortableness of a clutch pedal and meets the requirement of a large-torque engine manual-transmission car on a clutch manipulation system.
Description
technical field [0001] The invention relates to a clutch pedal mechanism, in particular to a clutch pedal assembly with a double booster spring mechanism. Background technique [0002] With the rapid development of engine technology (such as supercharging technology and direct injection technology), the engine torque is also gradually increasing, the clutch pressing force will increase, and the clutch torque capacity required by the corresponding manual transmission vehicle will also gradually increase. . The manual transmission car adopts a high-torque engine. In order to ensure the comfort of the clutch operation, the pedal stroke should not be too long (120-150mm is more suitable), and the pedal force cannot be reduced by increasing the lever ratio of the clutch pedal without limit. It is necessary to increase the assist value of the clutch pedal. [0003] At present, the clutch pedal of a manual transmission car generally passes through the center point spring mechanis...
