Abstract

A hybrid electric vehicle with an automatic clutch, which includes an engine, a gearbox, a clutch and an electronic control unit thereof, and is characterized in that: a start-generating integrated motor is arranged between the engine and the manual gearbox, and the motor passes through the starter The power generation integrated motor controller is connected with the power battery; the manual gearbox is connected with the friction plate clutch, clutch cylinder, clutch oil cylinder and executive motor mechanism in turn. The clutch adopts a conventional friction plate clutch, the gearbox adopts a manual gearbox, the conventional clutch pedal is canceled, and the clutch oil cylinder is driven by an executive motor, thereby pushing the clutch sub-cylinder and the release bearing to achieve the purpose of clutch separation. The structure of this scheme is simple, and it has advantages in terms of operating economy, because its transmission is still a manual transmission, so the fuel consumption is relatively low, and the manufacturing cost is also lower than that of automatic transmission and continuously variable transmission, which reduces the cost and fuel consumption of hybrid vehicles There are obvious improvements in all aspects.

Description

A hybrid car with an automatic clutch

technical field

The utility model belongs to the technical field of hybrid electric vehicles, in particular to a hybrid electric vehicle with an automatic clutch.

Background technique

With the depletion of energy and the seriousness of environmental pollution year by year, countries around the world are paying more and more attention to energy conservation and environmental protection. In the past 100 years of its development, the automobile industry has made remarkable improvements and great progress in energy saving, pollution, emission and other aspects, but the pollutants emitted by its tail gas are still the main pollution source of the earth's atmosphere today. The automobile industry consumes a large part of the world's oil production. Under this background, countries all over the world pay more and more attention to the research of hybrid electric vehicle technology, and major automobile manufacturers have invested a lot of money in the development of hybrid electric vehicles. There are many ways to realize the structure of hybrid vehicles. At present, the scheme of using a starter-generator integrated motor to realize hybridization is relatively common in China, and it is becoming more and more mature. A manual gearbox, an automatic manual gearbox or a continuously variable gearbox can be used for the starter-generator integrated motor solution, but the hybrid electric vehicle uses an automatic manual gearbox or a continuously variable gearbox. The cost is too high, and the structure Complicated, it is not convenient to improve on the basis of the original car, and must be redeveloped, which will cause the cycle to be too long, which is not conducive to the industrialization process of hybrid vehicles.

Contents of the invention

The purpose of the utility model is to provide a hybrid vehicle with an automatic clutch realized by low-cost partial improvement on the basis of the power system of the existing hybrid vehicle.

The purpose of this utility model is achieved in this way: it includes an engine, a gearbox, a clutch and an electronic control unit thereof, and it is characterized in that: an integrated motor for starting and generating power is arranged between the engine and the manual gearbox, and the integrated starting and generating The motor is connected to the power battery through the integrated motor controller for starting and generating; the manual gearbox is connected to the friction plate clutch, clutch cylinder, clutch oil cylinder and executive motor mechanism in turn.

The output end of the above-mentioned executive motor is directly connected with the push rod on the clutch oil cylinder.

Compared with the hybrid vehicle using conventional clutch, the utility model has the following advantages:

1) The structure is simple and the cost is low. Only the clutch pedal of the original car is canceled, and the executive motor and electronic control unit are installed.

2) Small changes to the original vehicle system. Hybrid vehicles are usually developed on the basis of traditional vehicles. Small changes to the original vehicle system can save development costs and shorten the development cycle.

The fuel consumption is better than that of similar hybrid vehicles, and it makes the hybrid vehicle start smoothly, facilitates gear shifting and prevents the drive train from overloading, and at the same time enables the vehicle control unit of the hybrid vehicle to better control the start-up and power generation under various working conditions. The motor works, and the large-scale industrialization of hybrid electric vehicles can be realized faster.

Detailed ways

Example 1

As shown in Figure 1, 1 in the figure is an engine, 4 is a manual gearbox, and 9 is an electronic control unit. An integrated motor 2 for starting and generating power is arranged between the engine 1 and the manual gearbox 4. The integrated motor for starting and generating power 2. The integrated motor controller 3 is connected to the power battery 10 through starting and generating; The clutch adopts a conventional friction plate clutch, the gearbox adopts a manual gearbox, the conventional clutch pedal is canceled, and an executive motor is used to drive the clutch oil cylinder, thereby pushing the clutch sub-cylinder and the release bearing to achieve the purpose of clutch separation. The executive motor is connected with the push rod of the clutch oil cylinder to become a component, and it is assembled on the gearbox by using the double-headed stud mounted on the suspension of the gearbox as the installation point. The electronic control unit collects signals such as clutch control stroke position, shift force, gear selection position, shift position, throttle position, engine speed, vehicle speed, ignition switch, brake light switch and other signals through sensors, and calculates the clutch Optimum combination and separation speed, while the clutch electronic control unit communicates with the vehicle control unit of the hybrid vehicle. The vehicle control unit controls the start-up and power generation integrated motor boosting, power generation or idling through the control strategy according to the vehicle parameters. In this way, the hybrid vehicle achieves a better optimization effect on the basis of the most concise improvement, ensuring the stability of power output and fuel economy.
