Abstract

The invention discloses a crawler chassis testing system and a testing method. An engine is connected with a variable pump through a connecting device; an oil outlet of the variable pump is connectedwith an oil tank through an overflow valve and is connected with oil inlets of manual reversing valves A and B through diverter valves; a port A of the manual reversing valve A is connected with a port A of a left side driving motor through a parallel branch path of a manual reversing valve C and a proportional overflow valve A, and a port B of the left side driving motor is connected with a portB of the manual reversing valve A through a parallel branch path of a proportional overflow valve B and a manual reversing valve D; a port A of the manual reversing valve B is connected with a port Aof a right driving motor through a parallel branch path of a manual reversing valve E and a proportional overflow valve C, and a port B of the right driving motor is connected with a port B of the manual reversing valve B through a parallel branch path of a proportional overflow valve D and a manual reversing valve F; and the left driving motor and the right driving motor are in drive connection with a left crawler belt and a right crawler belt through a left clutch and a right clutch correspondingly. According to the system and the method, the performance of the crawler chassis can be reliably tested.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a crawler chassis testing system and testing method. Background technique [0002] With the continuous improvement of the automation level of modern agricultural machinery, there are higher and higher requirements for the chassis of agricultural machinery. At the same time, the use of hydraulic chassis in agricultural machinery and construction machinery is gradually becoming popular. Compared with traditional mechanical chassis, The hydraulic chassis has a series of advantages such as flexible and convenient layout, stepless speed regulation and wide speed regulation range, and high degree of automation. At the same time, whether the performance of the hydraulic chassis is reliable is also the basis for ensuring the stable operation of agricultural institutions. There is no system for testing the hydraulic chassis in the prior art. Therefore, it is urgent to provi...
