Problems solved by technology

[0003] The purpose of the present invention is to overcome and solve the problem of friction and heat generated in low-speed dual-clutch automatic transmissions of existing automobiles, and to provide a protection device for dual-clutch automatic transmissions. Part of the power transmission of the engine is transmitted to the loader to consume energy, reduce the burden of friction and heat of the clutch, reduce wear and tear, and prolong the service life of the clutch

Embodiment Construction

[0014] Such as figure 1 Shown is an embodiment of a dual-clutch automatic transmission protection device according to the present invention. The controller 1 is electrically connected to the vehicle speed sensor 3 and the brake pedal displacement sensor 4 to collect the vehicle speed brake pedal displacement information. The controller 1 is connected to the loader driver 2 to control the control amount of the loader driver to the loader 7. The controller 1 is electrically connected to the brake 6, and the brake 6 is released when driving at a low speed, the power distribution mechanism 5 is mechanically connected to the loader 7 through the brake 6, and the loader 7 is electrically connected to the loader driver 2; the loader 7 can be an eddy current The dynamometer can be an electric dynamometer, or a magnetic powder brake; the brake 6 is a normally closed brake.

Abstract

The invention discloses a protective device of a dual-clutch automatic transmission. A controller 1 is electrically connected with a loader drive 2, a gear sensor 3, a brake pedal displacement sensor 4 and a brake 6; a power distribution mechanism 5 is mechanically connected with a loader 7 through the brake 6; and the loader 7 is electrically connected with the loader drive 2. The protective device aims to solve the problem of frictional heating of dual-clutch automatic transmissions of existing automobiles at a low speed, clutches of the transmission may not perform slip control when an automobile runs at a low speed, the power of an engine is partially transmitted to the loader, and the energy is consumed away, so that the frictional heating burden of the clutches can be alleviated, the abrasion can be reduced, and service lives of the clutches can be prolonged.

Description

technical field [0001] The invention relates to an automobile protection device, in particular to a double clutch automatic transmission protection device. Background technique [0002] When the front 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, if the vehicle speed is too low and the engine speed is too low, the engine will stall. To prevent the engine from stalling, the clutch of the transmission must adopt slip control, that is, the clutch is in a half-engaged and half-disengaged state, so the clutch of the transmission acts as a friction device, and the clutch plate will heat up. When driving, the friction plate of the clutch will wear out at an accelerated rate, which will affect the service life of the clutch and eventually cause transmission failure. In particular, there is no effective solution for the ...
