Abstract
A caterpillar tractor electric control suspension device with a convertible suspension mode and a limiting rod limiting comprises a lower drag link bearing, a force sensor, a short limiting rod assembly, an upper drag link assembly, a lower drag link assembly, a long limiting rod assembly, a suspension bearing, a lift shaft, a level sensor, a lift arm, a hydraulic cylinder and a lifting rod. The lower drag link assembly is connected with the lower drag link bearing through the force sensor, two ends of the short limiting rod assembly are respectively connected on the suspension bearing and the lower drag link assembly, the level sensor is connected with the lift shaft, the hydraulic cylinder is connected with the middle of the lift arm, two ends of the lift arm are respectively connected with the lift shaft and the lifting rod, and the other end of the lifting rod is connected on the lower drag link assembly. According to limiting of the limiting rod, the device solves the problem that a limiting chain is prone to be cracked when the limiting chain is limited. Compared with a traditional forced press into dust lifting device control suspension device, the electric control suspension device has the advantages that many in adjusting mode of tilling depth, simple and reliable in control to lift up and drop down, saving in adjusting force, high in sensitivity and the like.
Description
Technical field
The utility model belongs to the tractor field, relates to a kind of crawler tractor electronically-controlled suspension device, relates in particular to the spacing crawler tractor electronically-controlled suspension device of a kind of convertible hang gag lever post.
Background technology
At present, the crawler tractor of domestic production adopts trifilar suspension and 2 suspensions mutually to change and check chain is spacing, suppress the suspension arrangement of the lifter control of burying mostly.Position on car load is limit because of the reasons in structure of check chain own and hanging bar, and the check chain fracture occurs when hitch promotes farm implements easily; And suppress the lifter that buries, and highly regulate (floating control) and the adjusting of simple position because only having, make its tilling depth regulative mode single, and adopt mechanical, hand-driven to regulate, sensitivity is low, regulates effort, is difficult to satisfy modern big-power tractor electronics and ploughs the needs that rise control.
For overcoming the above problems, the utility model provide a kind of relatively simple for structure, easy to use and reliable, 2 hang and trifilar suspension can be changed mutually, with the spacing crawler tractor electronically-controlled suspension device of gag lever post.The easy disconnected problem of check chain when having solved by gag lever post is spacing that check chain is spacing; And adopt the electronically-controlled suspension device to suppress the lifter control suspension arrangement that buries with respect to tradition, have the advantages such as the tilling depth regulative mode is many, control lifting decline is simple and reliable, adjusting is laborsaving, sensitivity is high.
The utility model content
The crawler tractor electronically-controlled suspension device that provides a kind of hang gag lever post relatively simple for structure, easy to use and reliable, convertible spacing is provided the purpose of this utility model.
The technical solution of the utility model is: the crawler tractor electronically-controlled suspension device that convertible hang gag lever post is spacing comprises: lower link bearing, power sensor, short gag lever post assembly, upper connecting rod assembly, lower link assembly, long gag lever post assembly, suspended bearer, lift shaft, level sensor, lift arm, hydraulic jack, lifting arm; The lower link assembly is connected with the lower link bearing by the power sensor; The two ends of short gag lever post assembly are connected on suspended bearer and the lower link assembly; Level sensor is connected with lift shaft; Hydraulic jack is connected with the middle part of lift arm; The two ends of lift arm link to each other with lifting arm with lift shaft respectively; The other end of lifting arm is connected on the lower link assembly.
The lower link assembly is connected with suspended bearer by the power sensor; The two ends of long gag lever post assembly are connected on lower link bearing and the lower link assembly; Level sensor is connected with lift shaft; Hydraulic jack is connected with the middle part of lift arm; The two ends of lift arm link to each other with lifting arm with lift shaft respectively; The other end of lifting arm is connected on the lower link assembly.
The utility model can reach following beneficial effect: the easy problem of fracture of check chain when having solved by gag lever post is spacing that check chain is spacing; And adopt the electronically-controlled suspension device to suppress the lifter control suspension arrangement that buries with respect to tradition, have the advantages such as the tilling depth regulative mode is many, control lifting decline is simple and reliable, adjusting is laborsaving, sensitivity is high.
