Problems solved by technology

However, under some working conditions, the auxiliary steering pump does not need to run all the time. At this time, the auxiliary steering pump is in a no-load idling state, which causes vibration and abnormal noise, and the auxiliary steering pump runs at high speed for a long time, which will also affect its reliability.

Embodiment 1

[0034] see Figure 1 to Figure 4 As shown, a steering system provided by the present application includes an auxiliary steering pump 101 and a transfer case 102 ; the transfer case 102 includes a first intermediate shaft 103 , and the input end of the auxiliary steering pump 101 is connected to the first intermediate shaft 103 .

[0035] Specifically, for the chassis of a multi-axle single-engine crane, the main steering pump 114 is installed on the engine 112, and the input shaft of the transfer case 102 is connected to the transmission 113 through the main drive shaft, and the transfer case 102 with an intermediate shaft is generally used. Drive distribution. The input shaft of the transfer case 102 can transmit driving force to the output shaft through the intermediate shaft, and the output shaft is connected to the front axle 115 and the rear axle 116 of the vehicle body through the main drive shaft. When the crane is performing in situ hoisting operations, at this time, ...

Embodiment 2

[0045] The steering system in the second embodiment is an improvement on the basis of the above embodiment. The technical content disclosed in the above embodiment will not be described repeatedly, and the content disclosed in the above embodiment also belongs to the content disclosed in the second embodiment.

[0046] see Figure 3 to Figure 4 As shown, in an optional solution of this embodiment, the steering system further includes an emergency steering pump 107; the transfer case 102 further includes a second intermediate shaft 108, and the input end of the emergency steering pump 107 is connected to the second intermediate shaft 108.

[0047] When the main steering oil pump of the equipment fails, it is necessary to activate the emergency steering function, that is, to turn on the emergency steering pump 107 . In the prior art, the emergency steering pump 107 is generally installed on the transmission 113, and the transmission 113 needs to be equipped with a power take-off...

Abstract

The invention relates to the technical field of vehicle steering devices, in particular to a steering system and a crane. The steering system comprises an auxiliary steering pump and a transfer case.The transfer case comprises a first intermediate shaft. The input end of the auxiliary steering pump is connected with the first intermediate shaft. According to the provided steering system, the input end of the auxiliary steering pump is connected with the first intermediate shaft of the transfer case, no-load idling of the auxiliary steering pump is avoided, equipment vibration and abnormal sounds are reduced, and the service life of the auxiliary steering pump is prolonged.

Description

technical field [0001] The present application relates to the technical field of vehicle steering devices, in particular to a steering system and a crane. Background technique [0002] For cranes and other models with five axles and above, in addition to the configuration of mechanical steering, auxiliary steering needs to be added to reduce the steering force on the steering wheel and the turning diameter of the equipment. [0003] The existing auxiliary steering pump is generally connected to the rear power take-off of the engine. After the engine is running, the power take-off of the engine is in a constant rotation state, thereby driving the auxiliary steering pump to run. However, under some working conditions, the auxiliary steering pump does not need to run all the time. At this time, the auxiliary steering pump is in a no-load idling state, which causes vibration and abnormal noise, and the auxiliary steering pump runs at high speed for a long time, which will also a...
