Travel speed controlling device of cargo handling vehicle
专利汇可以提供Travel speed controlling device of cargo handling vehicle专利检索，专利查询，专利分析的服务。并且PURPOSE:To attain smooth travelling by increasing the rotational speed of an engine based on the operation of a cargo handling lever, etc., and letting the change in travel speed due to the increase asymptotic to the travel speed commensurating to the amount of operation of an acceleration pedal. CONSTITUTION:When a cargo handling lever 19 is operated while travelling at a low speed which is detected by a car speed sensor 14, a CPU 22 drives an actuator 7 through a drive circuit 25 to increase throttle opening for cargo handling operation, and temporarily returns a clutch 2 toward the side of disengagement through a drive circuit 26 and an actuator 8 to temporarily weaken the transmission torque to a change gear 3 and increase the rotational speed of an engine 1. The semiengaged state of the clutch 2 is so controlled that the change in car speed due to the increase in the rotational speed of the engine as detected by the sensor 14 approaches a car speed commensurating to the amount of stepping down an acceleration pedal 16. Smooth travel is maintained this way to perform good cargo handling operation.，下面是Travel speed controlling device of cargo handling vehicle专利的具体信息内容。
