Loader static pressure transmission control system

Abstract

The invention discloses a loader static pressure transmission control system which comprises a controller. The controller is respectively connected with a transmission shaft rotation speed sensor, a brake pedal displacement sensor, a direction switch, a display, an operating panel, a diagnosing opening, an accelerator pedal displacement sensor, an engine rotation speed sensor, a travelling pump, a first motor, a second motor and a gearbox. The traveling pump is connected with an engine. One end of the gearbox is connected with a bridge. The other end of the gearbox is connected with the first motor and the second motor. The loader static pressure transmission control system has the advantages that the loader static pressure transmission control system is convenient to operate and control, safe and reliable, stable and soft in vehicle speed change and convenient to mount and maintain, transmission system efficiency can be increased greatly, full-automatic stepless speed change is achieved, reasonable engine power output distribution and utilization by vehicles are achieved, fuel consumption is lowered, energy is saved, multiple vehicle operation parameters can be checked on instruments, multiple misoperation simulating and safety prompting functions are provided by the system, and operation safety is increased.

Description

technical field [0001] The invention relates to a static pressure transmission control system of a loader, which belongs to the technical field of loaders. Background technique [0002] At present, the mainstream loaders on the market generally use hydraulic transmission, and the power of the engine is transmitted to the gearbox through the torque converter, and the gearbox drives the front and rear axles. The engine drives the pump wheel of the torque converter, and the power is transmitted to the turbine wheel of the torque converter through the working oil in the torque converter housing. Due to the joint action of the pump wheel, the turbine wheel and the guide wheel in between, the torque converter can operate within a certain range. The output speed and torque are automatically adjusted according to the size of the load. This type of equipment generally does not need an electronic control system, and the switching of driving gears depends on the self-adjustment of the ...
