Disclosed is an integrated manual automatic stepless gearbox mechanism based on a clutch-brake system with left foot operating brake pedal and right foot controlling accelerator pedal which is of an intrinsic safety model, free from pedaling by misplay or pedaling both simultaneously and puffs of black soot. A lotus gearlever assembled with lotus petal-type clutch switches is capable of being used in a fully manual mode and an automatic mode, in which the gearlever is coupled to a motor-drove gearbox by means of a flexible to rigid mechanical joint, and the traditional gearbox is upgraded to a stepless transmission device in virtue of 3-loop PID control strategy in the C program loaded in the Single Chip microcomputer named SCM to control. according to the driver's intention the device can shift gear, shift over gear or shift far gear automatically, Via a HMI the C program can set the various performances of the car such as smooth and comfortable mode or a sporty and powerful mode, thus making driving easy and as personal as ones wish. This invention further comprises two half-stroke mechanical clutch pulling bars, one half-stroke brake pulling bar, and one half-stroke sliding wire-wound rheostat type clutch pulling pole. |

1. an integrated automatic manual stepless gearbox device, its characters lies in, a brake pedal is arranged on the left while an accelerator pedal is arranged on the right and without clutch pedal in the driver's cab, integrated automatic and manual function, the automatically drove traditional gearbox obtained the function of stepless speed change via being regulated by the 3 loops PID control program which loaded in the microcomputer, according to the driving intention the device can shift gear automatically, has the functions of starting-up with higher gear, starting-up smoothly, driving at low speeds smoothly, isolating the clutch action at low speeds or when braking, the gearlever can be put in neutral location automatically after stopping, setting the various performances of the car via the human machine interface named HMI;
A lotus gearlever (6,61) is assembled with 3 or 4 lotus petal-type clutch switches which form a semiclosed shell coating on the top of gearlever, in the C program the logic value of OR of signal of said manual clutch switches are used for shifting gear or alternating the modes between the automatic and the manual, the states of the signal can be keep till the clutch discs arrive its end location of detaching or meshing and can be locked each other, in the conditions of manual mode and no instruction of detaching the clutch at low speed by force the clutch will detach when the clutch switches switched on and will mesh when the clutch switches switched off, associates with the lotus gearlever to accomplish the action of shifting gear, the clutch cannot mesh in the travel of shifting gear, in the automatic mode can shift gear but can not operate the clutch; The lotus gearlever (61) links with the mechanical gearlever (64) through the mechanical joint, the two levers said above integrate into a gearlever, in the automatic mode the gearlever is flexible and in the manual mode the lever is rigid; Based on the concept of the brake-clutch system vehicle brake device, the brake pedal said above can replace with a clutch pedal and a brake pedal which controlled by the left foot, or replace with a pedal operated by left foot which integrate the normal brake pedal and the normal clutch pedal named clutch-brake pedal, in such cases, in the conditions of low speeds or starting the clutch-brake pedal or the clutch pedal control vehicle to run or detach the clutch to stop by the mean of un-fully meshing of the clutch, in the condition of braking when the vehicle speed exceeding the set value the device can shields the clutch actions and leads the engine to be idle. |
