Title:
SYSTEM FOR PREVENTING FROM ROLLING BACK DOWN SLOPE, FOR INDUSTRIAL VEHICLE AND CONSTRUCTION EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2020/013553
Kind Code:
A1
Abstract:
The present invention relates to a system for preventing from rolling back down a slope, for an industrial vehicle and construction equipment, whereby, when the speed of a vehicle measured by a speed detection sensor is detected to be below 0 km, a transmission control part controls so that an advance-side solenoid valve and a reverse-side solenoid valve are configured to be turned off so that a supply of a working fluid and the hydraulic pressure of the working fluid supplied to an advance clutch part and a reverse clutch part is cut off, thereby enabling the advance clutch part and the reverse clutch part to be connected to an axle part of the vehicle, and when an accelerator pedal switch is turned on, the transmission control part controls so that the advance-side solenoid valve is configured to be turned off, and the reverse-side solenoid valve is configured to be turned on so that the supply of the working fluid and the hydraulic pressure of the working fluid is applied only to the reverse clutch part, thereby enabling the connection between the reverse clutch part and the axle part of the vehicle to be released.
