Protecting and energy recovery device of dual-clutch automatic transmission

Abstract

A protecting and energy recovery device of a dual-clutch automatic transmission comprises a controller 1, a brake pedal displacement sensor 2, a vehicle speed sensor 3, a dynamometer drive 4, an energy consumption device 5, a power distribution mechanism 6, clutches 7, a speed increaser 8 and an electric dynamometer 9. According to the device, the clutches of the transmission do not perform slip control when an automobile runs at a low speed, in addition, the energy can be recovered into a storage battery, and excess energy is consumed away through the energy consumption device, so that frictional heating of the clutches can be alleviated, the abrasion can be reduced, and service lives of the clutches can be further prolonged.

Description

technical field [0001] The invention relates to an automobile protection device, in particular to a dual-clutch automatic transmission protection and energy recovery device. Background technique [0002] When the current dual-clutch automatic transmission is moving forward at low speed, especially when the vehicle speed needs to be reduced without stepping on the accelerator, it is necessary to step on the brakes. At this time, in order to prevent the engine from stalling, the clutch of the transmission must adopt slip control, that is, It is half-engaged and half-disengaged, so the clutch of the transmission acts as a friction device, and the clutch plate will heat up. When the car needs to drive at a low speed for a long time in traffic jams, the friction plate of the clutch will accelerate wear and affect the service life of the clutch. , eventually causing transmission failure. In particular, there is no effective solution for the dry dual-clutch automatic transmission....

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome and solve the problem of clutch friction and heat generated at low speeds in existing dual-clutch automatic transmissions of automobiles, and to provide a protection and energy recovery device for dual-clutch automatic transmissions, so that the transmission clutch does not slip when the automobile is running at low speed control, and energy recovery can be carried out into the battery, and the excess energy is consumed by the energy consumer, which reduces the burden of friction and heat generation of the clutch, reduces wear and tear, and thus prolongs the service life of the clutch
