Automated manual mechanical stepless speed change device

Abstract

Disclosed is an automated manual mechanical stepless speed change device. A brake is arranged on the left while an accelerator is arranged on the right, the automated manual mechanical stepless speed change device is intrinsically safe, the brake and the accelerator cannot be stepped mistakenly and can be stepped simultaneously, and black smoke is eliminated. A lotus-shaped gear shifting handle with a lotus petal type clutch switch can be used in a purely manual mode and an automatic mode, and is connected with a gear shifting handle of an electric transmission box via hard and soft chain links, a traditional gear transmission box is upgraded into the stepless speed change device via a three-loop PID (proportion integration differentiation) adjuster, automatic gear shift and trip stop are realized according to driving intention, a computer program with the functions is developed, automobile maneuverability such as stableness and comfortableness or fast speed and high power can be optionally set by means of human-machine interaction HMI, and accordingly a driver can randomly drive an automobile with the automated manual mechanism stepless speed change device with facility. The automated manual mechanical stepless speed change device further comprises an upgraded clutch and brake system speed changing device, two semi-stroke mechanical clutch draw bars, a semi-stroke brake draw bar and a semi-stroke scribing resistance type clutch draw bar, and the upgraded clutch and brake system speed changing device shields clutch actions and leads an engine to be idle during braking after the speed of the automobile exceeds a set value.

Description

[0001] technical field [0002] The present invention relates to a motor vehicle speed change device based on a brake system, in particular to a manual-automatically integrated mechanical continuously variable speed change device and an upgraded version of a manual speed change device, as well as their computer programs and accessory structures. Background technique [0003] At present, all kinds of manual transmission motor vehicles must step on the clutch pedal when changing gears, coupled with frequent and complicated actions such as the accelerator and brake pedals, when the traffic in the urban area is busy and on complex road sections, it is easy to step on the accelerator or brake by mistake, resulting in major traffic Accidents, causing great loss of life. The brake pedal and accelerator pedal of many manual and automatic transmission cars also follow the layout scheme when the car was invented, and are all arranged on the right side of the cab to be operated by the ...

Problems solved by technology

[0004] Currently widely used manual transmission motor vehicles, gear transmission, good power, no kinetic energy loss, is unmatched by other transmission devices, but because of the stepped transmission, it brings a sense of frustration when changing gears, and the operation is complicated, so it is not suitable The limousine, that is, the transmission device with excellent power transmission performance and continuously variable transmission characteristics, has been the dream pursued by many automobile manufacturers in the world for more than 100 years. Therefore, many transmission devices have been developed: hydraulic coupling transmission , dual-clutch transmission, planetary gear transmission, belt-type continuously variable transmission, metal chain-type continuously variable transmission and so on, but there are more or less unsatisfactory defects, either the power is insufficient, or the speed change is not smooth enough , it is precisely such defects, contradictions, and people's endless pursuit that bring impetus to the development of things, and promote the continuous development of automobile transmission devices. After encountering many difficulties, people turn their heads to look at the mechanical Gear transmission devices, confused by its excellent power characteristics, competed to develop gear-type continuously variable transmission devices. Various mechanical automatic transmission devices appeared in the 1970s and 1980s in the world, including electric, hydraulic and pneumatic. According to the resource advantages of motor vehicles, the power scheme is selected, but the disadvantage is still the problem of uneven shifting. In view of this, even if the gear-type transmission is automated, it is also included in the low-gear ranks, and it has been wronged for a long time. , unrefined
