Loader traction transmission system and transmission control method

Abstract

The invention relates to the field of loader power transmission, aims to solve the problem that in a conventional loader traction transmission system, the traction transmission ratio cannot be regulated, and provides a loader traction transmission system which comprises an engine, a hydraulic torque converter, a gearbox, drive axles, a deceleration pedal, a clutch and a clutch control device, wherein the clutch is connected between the hydraulic torque converter and the gearbox; the deceleration pedal is connected with the clutch control device; when the deceleration pedal is within a front travel range, no brake action is taken by a brake system, and the engagement pressure of the clutch is controlled by the clutch control device according to the travel of the deceleration pedal; and when the deceleration pedal is within a rear travel range, the brake action is taken by the brake system according to the travel of the deceleration pedal. The loader traction transmission system provided by the invention has the advantages that the engagement pressure of the clutch is controlled through the front travel of the deceleration pedal, so that the trackslip of the clutch can be achieved, as well as the output rotational speed and the output torque can be changed and regulated; and when the deceleration is needed, the traction is regulated and reduced, so that the interruption in power transmission can be avoided and the safety of a complete loader can be improved.

Description

technical field [0001] The invention relates to a loader transmission, more specifically, to a loader traction force transmission system and a transmission control method. Background technique [0002] Loaders often carry out short-distance shoveling operations. It is often encountered that the loader has arrived at the truck, but the bucket of the loader has not been lifted. It is necessary to step on the brake and increase the accelerator of the engine at the same time. The kinetic energy of the whole machine is converted Heat energy is transferred to the bridge for braking energy. high temperature of the bridge. [0003] When the loader is working on the ramp while increasing the accelerator while walking and lifting, due to the high speed and stepping on the brake pedal, the driving power of the whole machine will be cut off immediately, and the whole machine will slide downhill. If the brake pedal does not stop If you step on the Panasonic and open it, the whole machi...
