High Power Gear Box or Transmission for Wheel Loaders

INTRODUCTIN FOR GEARBOX TMG075431.Over viewThe TMG 07543 type hydraulic transmission (hereinafter referred to as the transmission) consists of a YJH315 type hydraulic torque converter and a transmission with four forward gears and three backward gears.YJH315 The hydraulic torque converter is a single-stage two-phase integrated torque converter, with the characteristics of high efficiency and large torque change ratio. The gearbox is downshaft type, with the front four and rear three shift function, built-in working oil pump, external force port.2. Main technical parametersRated input power of the matching engine 75kWRated input speed of the matching engine  2400r / minInput shaft steering (facing the transmission output) counter clock wiseWorking fluidNo.6 or No.8 hydraulic transmission oilMain oil pressure and retaining oil pressure1.6MPa~1.9MPaTorque converter oil inlet pressure0.4MPa~0.8MPaTorque converter oil return pressure 0.22MPa~0.4MPaWorking oil temperature80ºC ~100ºCRated voltage of the solenoid valve  DC24VAbout TMGTMG is a professional trackless mining equipment, engineering equipment manufacturer.Our production base is located in Qingzhou, Shandong.Our products include: underground trackless mining equipment (underground loaders, underground mining trucks, utility vehicles, drill jumbos, drivetrain system transmission, torque converter, axle); engineering equipment ( wheel loaders, backhoe loaders, excavators, telescopic handlers,graders, articulated dump trucks); drive-train system (transmission, torque converter, axle).Besides,as a technology oriented enterprise, we also provide customers with solutions including drive-train system customization, vehicle transformation and project contracting etc.ImprovementThe torque converter is easy to heat up Inability to climb hillsClimbing long slopes is prone to overheating PunchEasy to burn the friction plate Loud noise  Cause Analysis Small horse-drawn cart The hydraulic flow of the charging oil is low and the pressure fluctuates greatly Comparison with Top Euro brand Customized design to solve customer pain points Short lead time, 3 monthsElectrically controlled shifting and automatic shifting mode are adopted to reduce shifting impact and protect gears from damageHydraulic torque converter has large circulation, large transmitted torque, large traction and strong climbing ability. ChangeTorque is not easy to heat up. The clutch structure is improved to reduce the friction plate burning phenomenon caused by the inaccurate control of the engagement time of the two clutches during the shifting process. The gear is thickened to improve the reliability of the gearbox. Higher reliability and longer life.Payload 6~7 ton Calculation details Diesel Engine ModelkWTorque Converter Transmission Traction kN1st  km/h 2nd  km/h 3rd  km/h 4th  km/h Deutz BF6M 1013EC165KW165YJ330(C273.1)RC33429175.534.879.6818.2825.66Deutz BF6M 1013EC165KW165YJ330(C273.1)RC33428178.744.799.5217.9724.57CUMMIS B67CS4162YJ330(C273.1)RC33429156.474.849.6317.1225.04CUMMIS B67CS4162YJ330(C273.1)RC33428166.154.569.0817.1923.59Volvo TAD850VE162YJ330(C273.1)RC33429159.715.0610.2818.8227.53Volvo TAD850VE162YJ330(C273.1)RC33428169.574.769.4417.7224.11  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
