Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 走行する場所の傾斜角度による走行抵抗にも かかわらずブレードに加わる掘削押土の負荷量を常に一 定に保たせることができるブルドーザのブレード制御装 置を目的とする。 【構成】 車体の前後方向の傾斜角度を検出する傾斜角 検出手段、車体の実牽引力を検知する実牽引力検知手段 および、この実牽引力検知手段により検知される実牽引 力を前記傾斜角検出手段により検出される傾斜角度にも とづき補正し、この補正された実牽引力が目標実牽引力 に一致するようにブレードを上昇若しくは下降させて制 御する制御手段を具える構成とする。 (57) [Abstract] [Purpose] An object of the present invention is to provide a blade control device for a bulldozer capable of keeping the load of excavated soil applied to the blade constant regardless of the traveling resistance due to the inclination angle of the traveling place. [Structure] An inclination angle detecting means for detecting an inclination angle of a vehicle body in the front-rear direction, an actual traction force detecting means for detecting an actual traction force of the vehicle body, and an actual traction force detected by the actual traction force detecting means are detected by the inclination angle detecting means. It is configured to include a control unit that performs correction based on the tilt angle, and raises or lowers the blade so that the corrected actual traction force matches the target actual traction force.
