Prime mover combined control device and prime mover control method

Abstract

The invention relates to the technical field of engineering vehicles, in particular to a prime mover combined control device and a prime mover control method. The prime mover combined control device comprises a control key; the control key comprises a key switch and a knob switch arranged around the outer side of the key switch; the on-off states of a prime mover can be controlled by operating thekey switch; and the knob switch is in communication connection with the prime mover, the knob switch is provided with a plurality of working gears, and an operator rotates the knob switch so that theknob switch can be switched between the different working gears, ignition starting of the prime mover in the power-on state can be controlled, and the started prime mover can execute gear shifting operation. According to the prime mover combined control device, the control key integrates the key switch used for controlling the prime mover to be powered on and off and the knob switch used for starting the prime mover and achieving gear adjustment, the size is small, the occupied installation space is smaller, and the occupied space in a cab of an engineering vehicle is saved; and meanwhile, functions are complete and operation is convenient.

Description

technical field [0001] The present application relates to the technical field of engineering vehicles, in particular to a prime mover combination control device and a prime mover control method. Background technique [0002] Construction machinery is usually started with a mechanical key, and the key gears are generally warm-up gear, stop gear, power-on gear and prime mover gear; with the advancement of technology, the one-button starting device on cars is gradually favored by young operators. The demand for equipment on construction machinery is also becoming stronger. However, there are obvious differences between crawler-type construction machinery and automobiles, such as no brake pedal; therefore, the one-button starting device and starting method on automobiles cannot be directly applied; moreover, the cab space of construction machinery is very compact, if the original If the mechanical key start mode is converted to a one-button start device, a gear adjustment knob ...

AI Technical Summary

Problems solved by technology

However, there are obvious differences between crawler-type construction machinery and automobiles, such as no brake pedal; therefore, the one-button starting device and starting method on automobiles cannot be directly applied; moreover, the cab space of construction machinery is very compact, if the original The mechanical key start mode is converted to a one-button start device, and a gear adjustment knob for the prime mover needs to be added, which takes up a lot of space and has a poor operating experience
