Description
Technical field: the utility model relates to a kind of speed and reversing gear of bivariate pump double motor running on wheels machinery.
Background technology: at present; Existing hydraulic pressure running on wheels machinery is to control the speed of travel and switching-over with single pump and change speed gear box mostly, when walking and switching-over, needs governing speed and switching-over gear, and speed is discontinuous; Regulate loaded down with trivial details; The operating personal technical merit is required height, and misoperation is wasted fuel easily.
Summary of the invention: the purpose of the utility model is to overcome above-mentioned shortcoming; A kind of speed and reversing gear of bivariate pump double motor running on wheels machinery are provided; It has mainly solved existing hydraulic pressure running on wheels machinery is to control the speed of travel and switching-over with single pump and change speed gear box mostly; Speed is discontinuous, regulates problems such as loaded down with trivial details, waste fuel.The speed that the purpose of the utility model is achieved in that bivariate pump double motor running on wheels machinery and reversing gear are by shifter bar, guide pin bushing, swing arm pull bar, the universal pull bar of swing arm, swing arm, bearing pin, direction rotating disk, direction rotating disk carriage, convex balance staff, convex balance staff support, frame, the universal rotating shaft of pull bar, pull bar, oil pump control pull rod, shifter bar guide pin bushing, shifter bar guide shaft formation.Shifter bar is fixed on the shifter bar guide shaft, and the shifter bar guide shaft is contained in the shifter bar guide pin bushing, and the shifter bar guide pin bushing is installed on the frame; Guide pin bushing is contained on the shifter bar, and swing arm pull bar one end is installed on the guide pin bushing, and the other end is installed on the universal pull bar of swing arm; The swing arm upper end is installed on the universal pull bar of swing arm, and the convex balance staff is fixed on the lower end of swing arm, and is connected with direction rotating disk carriage with convex balance staff support respectively; Convex balance staff support is fixed on the frame, and pull bar one end is connected with the oil pump control pull rod, and the other end is connected with the universal rotating shaft of pull bar; The universal rotating shaft of pull bar is contained on the direction rotating disk, and the direction rotating disk is connected with direction rotating disk carriage through bearing pin.This product structure is simple, and is reasonable in design, when walking and switching-over, can realize stepless change, makes the soft starting of vehicle, and speed change is impacted ground conversion travel direction with nothing rapidly, operates steadily, and dependable performance is manipulated safe ready, and fault rate is low, and is easy to maintenance.
