Embodiment Construction

[0021] Such as figure 1 As shown, the automatic shifting system of the specific embodiment of the present invention includes: a gearbox, a control system, a position selection mechanism connected with an operating mechanism, and a shift mechanism, and the position selection mechanism and the shift mechanism are installed on the gearbox .

[0022] The control system includes an electronic control unit and a solenoid valve, and the solenoid valve is respectively connected with a position selection mechanism and a shift mechanism. The solenoid valves include S0, S1, S2, S3 and S4 as shown in the figure, wherein S0, S1 and S2 are used to control position selection, and S3 and S4 are used to control gear shifting. The pressure oil p enters the system through the solenoid valve S0-S4.

[0023] The position selection mechanism is used to control the axial movement of the position selection piston rod to complete the position selection operation. The position selection mechanism in...

Abstract

The invention discloses an automatic transmission system which comprises a gearbox, a control system, a position choosing mechanism connected with an operation mechanism and a transmission mechanism, wherein the position choosing mechanism and the transmission mechanism are arranged on the gearbox. By adopting the automatic transmission system, the accuracy of transmission operation is improved; and owning to the integral design with the gearbox, the integral hoisting of the automatic transmission device of the gearbox becomes convenient, thus bringing convenience for installation and maintenance.

Description

technical field [0001] The invention relates to a transmission system of a vehicle, in particular to an automatic shifting device for a fixed-axle gearbox of a crawler vehicle. Background technique [0002] The structure of the fixed-axis gearbox for tracked vehicles is quite different from that of manual fixed-axis gearboxes for wheeled vehicles. Usually, it is more laborious to operate the manual fixed-axis gearbox for tracked vehicles, and the demand for automatic transmission is more urgent. [0003] The automatic shift control device of the fixed-axis gearbox of the tracked vehicle can be installed in the cab, which is relatively easy to arrange, and can use the vertical shaft and self-interlocking devices of the original vehicle. However, this installation method will seriously affect the accuracy of the shifting operation due to the deformation of the vehicle body, the deformation of the tie rod and the relative movement between the vehicle body and the gearbox during...
