Problems solved by technology

When driving on uneven roads, due to the limitation of the number of drive axles that can be driven, the wheels driven by some drive axles may slip, which will reduce the driving power of the crane, especially in the case of heavy loads. Insufficient driving force will seriously affect the traveling speed of the crane, and even make the crane unable to move

Embodiment Construction

[0029] In order to solve the problem of insufficient driving force under the condition of heavy load of the crane, the embodiment of the present invention adds an independent hydraulic drive device to the drive system of the crane chassis, so that the crane can change from the original driving mode that only relies on the mechanical drive device to provide power. The dual power mode of the mechanical driving device and the hydraulic driving device can provide driving force to the crane simultaneously with the mechanical driving device on the one hand, improving the driving force of the crane. On the other hand, when the crane is driving on uneven roads, even if part of the mechanical drive axle slips, the hydraulic drive device can be used to provide driving force for the crane, thereby improving the off-road driving ability and off-road performance of the crane chassis.

[0030] Embodiments of the present invention will be described in detail below with reference to the accomp...

Abstract

The invention relates to the field of machinery and in particular relates to a chassis driving system of a crane, a chassis and the crane, and the chassis driving system comprises at least one mechanical drive axle, mechanical driving devices used for driving all the mechanical drive axles, at least one hydraulic drive axle, and hydraulic driving devices which are connected with all the hydraulic drive axles and are used for driving all the hydraulic drive axles. The chassis driving system of the crane is additionally provided with the hydraulic driving devices based on the original mechanical driving devices, and a hydraulic system is used for driving a hydraulic motor to drive more drive axles to run, so that the travel driving force of the crane is effectively improved, the phenomenon of insufficient driving force caused by heavy load or wheel-slip can be reduced, and the load travelling capability of the crane can be improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a crane chassis drive technology. Background technique [0002] At present, the crane chassis generally uses mechanical equipment to drive the drive axle, such as figure 1 As shown, engine 1 ' transmits power to front drive axle 61 ' and rear drive axle 62 ' through clutch 2 ', gearbox 3 ', transmission shaft 4 ', transfer case 5 '. For multi-axle cranes, especially cranes with more than eight axles, according to the current technology, the front and rear drive axles can only achieve double linkage and triple linkage at most. For example, as shown in the figure, the front drive axle 61' is triple linkage, and the rear drive axle 62 'For two linkage. When driving on an uneven road, due to the limitation of the number of drive axles that can be driven, the wheels driven by some drive axles may slip, which will reduce the driving power of the crane, especially in the case of heavy loads. I...
