Automated manual mechanical stepless speed change device

Abstract

Disclosed is an integrated automatic manual, mechanical-type stepless transmission device based on a clutch-brake system with a left pedal brake and a right pedal accelerator, which is of an intrinsic safety model, free from erroneous treading on pedals, the fear of treading on both pedals at the same time, and puffs of black soot. A lotus gearshift lever provided with a lotus petal-type clutch switch is capable of being used in a fully manual mode and an automatic mode, in which the gearshift lever is coupled to a motor-driven gearbox by means of a flexible to rigid link, and the traditional geared transmission is upgraded to a stepless transmission device by means of a three-loop PID controller, so that according to the driver's intention, the gear shifting and trip shifting are automatically performed, and a computer program for achieving the above mentioned functions is developed, with a human machine interface (HMI) being capable of setting at will the vehicle manoeuvrability, such as a smooth and comfortable type or a sporty and powerful type, thus making driving easy and as personal as one wishes. The invention further comprises an upgraded transmission device for a clutch-brake system, which system isolates the clutch action when the vehicle is braking after its speed has exceeded a set value, so as to set the engine at an idling speed, together with two half-stroke mechanical clutch pulling bars, one half-stroke brake pulling bar, and one half-stroke adjustable wire-wound resistor-type clutch pulling bar.

Description

technical field [0001] 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 [0002] 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 right foo...

Problems solved by technology

[0003] 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
