Automatic clutch for car driving mechanism based on helicoid spring compensation

Abstract

The invention relates to an automobile automatic clutch driving mechanism based on a volute compensation spring. Produced automatic clutch control systems are not formed in our country at the moment. The automatic clutch driving mechanism is an important component part of the automatic clutch control system. The automobile automatic clutch driving mechanism comprises a direct current driving motor arranged on a bracket and a self-locking worm and gear retarding mechanism connected with the clutch driving mechanism. A center driving shaft (13) arranged in a cylindrical steel barrel is connected with a worm wheel of the self-locking worm and gear retarding mechanism. The center driving shaft is respectively connected with a driving disc (1) and the inner end of a volute compensating spring (5). The driving disc is connected with a clutch inhaul cable (2). The outer end of the volute compensating spring is connected with a cylinder (11). The volute compensating spring is pre-tightened in advance before being arranged. The cylinder is internally provided with a mechanical position-limit mechanism (4), the volute compensating spring and a side angular position sensor (6). The automobile automatic clutch driving mechanism is applied to the automobile automatic control field.

Description

Technical field: [0001] The invention relates to an automobile automatic clutch drive mechanism based on scroll spring compensation. Background technique: [0002] Automatic clutch is the core and difficult technology of automatic transmission of automobile machinery. At present, there is no commercialized automatic clutch control system in our country. The automatic clutch driving mechanism is an important part of the automatic clutch control system, and there is no formed product in this aspect in China at present. [0003] An existing automatic clutch control device is composed of a motor, a worm gear reduction mechanism, a spring accumulator, a drive cylinder and a controller. The accumulator adopts a telescopic spring, which plays a positive torque compensation role when the clutch is disengaged, and a reverse compensation role when the clutch is engaged. After disengagement and in the process of engagement, the compensation force and torque generated by the compensat...

AI Technical Summary

Problems solved by technology

The design process of the telescopic spring compensation mechanism is complicated, and the versatility is not strong, especially after the clutch wears out, the compensation function will become poor or even unavailable

In addition, the output end of the device adopting the form of worm gear and worm transmission adopts the form of push rod, which brings inconvenience to the connection and layout of the driving mechanism

Another point is that no mechanical limit mechanism is designed. If a failure occurs, the clutch will be seriously damaged. The reliability of its work needs to be further verified.
