Description
Technical field
The utility model relates to control technique, particularly a kind of motor vehicle gear changing prompting technology.
Background technique
Present truck crane substantially all is that the band portion boom hoisting of getting on the bus travels in the road weight scope that car load allows, but the maximum weight that the boom hoisting weight of most full-sized car hoists all surpasses car load to be allowed when travelling, but consider the convenience of use, usually allow hoist band part boom hoisting to do short-range overload and travel, the rideabilities such as the acceleration of corresponding vehicle, grade ability will variation.But the operator often still follows the operating habit steering vehicle under the normal travelling state, and this is just easily because misoperation causes the abnormal damage of vehicle sections element or the reduction that the user estimates vehicle performance.
Truck crane is when climbing is travelled at present, basically take two kinds of ways for the selection of gearbox gear-shift point: the one, manual vehicle or automatic transmission vehicle are in manual mode when travelling, only rely on user's experience need to judge whether gear shift, that is to say that the truck crane of the transfer case of coupling more than two grades is when climbing is travelled, for the selection of transfer case gear, be to rely on user's experience to determine fully; The one, the automatic transmission vehicle is in automatic shift mode when travelling, and gearbox is according to current vehicle running state parameter, determines to carry out automaitc shfit by shift point such as current vehicle acceleration, when front haulage or pushing torque, running resistance etc.
Manual vehicle or automatic transmission vehicle are in truck crane that manual mode travels when climbing is travelled, and only rely on user's experience to determine the gear shift of gearbox and not exclusively reliable.In large slope travels, often occur easily causing that because gearbox lowers category to select to lag behind the vehicle climbing is short of power, and then cause the problems such as cltuch slipping, wheel-slip, Transmitted chains damage.
The automatic transmission vehicle is in truck crane that automatic shift mode travels when climbing is travelled, definite main consideration grade ability and the gear shift travelling comfort of shift point, less consideration gearbox heating problem, particularly with the automatic transmission case of fluid torque converter, it is ultimate attainment for grade ability is performed to, under each climbing operating mode, all be to increase with fluid torque converter first to turn round, lower category again if can not satisfy the needs that travel, so the change of fluid torque converter is turned round than all larger under this type of driving cycle; And the change of fluid torque converter is turned round than larger, and transmission efficiency is lower, that is to say that a large amount of mechanical energy that this moment, motor passed over all need by changing into heat energy, and this just causes the gear box oil temperature rise; In order to reduce the speed change oil temperature, also cool off gear box oil with engine cooling system with the automatic transmission case of fluid torque converter.During especially large, long ramp driving, if gearbox drops to low grade from top grade step by step, cause easily the heat energy accumulation that mechanical energy is transformed into, cause TOT Transmission Oil Temperature higher, and then cause that engine coolant temperature is higher, may cause gearbox or motor to damage.
Therefore, the suitable gear of How to choose is driven, extremely important, especially heavier for the load truck crane of safety traffic during for the climbing of Motor Vehicle.
