Wherein, the electronic control accuracy of surging is high, stable action, and driving force is large, the most reliable, is generally applicable to various, is not subject to the limitation of transmission torque size.But its processing cost is high, control system is complicated, and existing actuator is mostly proportional valve control, controls difficulty large, higher to the demand of hardware.If application number is 201010531169.1, denomination of invention is that the disclosed prior art of the patent application of " electrical control hydraulic automatic variable-speed system " is controlled gear selecting manipulation module by gear selecting solenoid valve and gear-shifting solenoid valve respectively, by clutch proportional solenoid valve control clutch control module, exist different conventional gear box of the same type to mate difficult problem.Therefore, be necessary existing hydraulic automatic shift module of transmission to improve, simple control structure, reduces manufacture cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hydraulic automatic shift module of transmission, and control structure is simple and reliable, reduces manufacture cost.
The present invention solves the problems of the technologies described above the technological scheme adopting to be to provide a kind of hydraulic automatic shift module of transmission, comprise body, gear selecting shifting block and gear shift shifting block, wherein, described gear selecting shifting block two ends are connected with gear selecting piston respectively, and described gear shift shifting block two ends are connected with gear shift piston respectively; Reverse shift fork is fixed on body by orientation axes and reverse shift fork can be freely movable with orientation axes; On gear shift shifting block, shift shaft is installed, the axis of guide is inserted in one end of shift shaft; Described orientation axes and shift shaft are for being slidably connected; Positioning shaft is fixed on body, and described gear selecting shifting block is provided with sliding-groove, and described gear selecting shifting block and positioning shaft are slidably connected; The gear selecting shifting block that gear selecting piston is controlled moves left and right the gear selecting that realizes speed changer, and gear shift piston up-down drives reverse shift fork to complete gear shift action.
Above-mentioned hydraulic automatic shift module of transmission, wherein, the vertical setting of oil cylinder at described gear selecting piston and gear shift piston place.
Above-mentioned hydraulic automatic shift module of transmission, wherein, on described gear selecting oil cylinder end cap and gear shifting oil cylinder end cap, being furnished with respectively diameter is the oil sources interface of 4mm.
The present invention contrasts prior art following beneficial effect: hydraulic automatic shift module of transmission provided by the invention, by two cover hydraulic jacks, control respectively gear selecting and gear shift, thereby can utilize two groups of hydraulic jacks to promote respectively the realization of gear selecting reverse shift fork by the direction of control reversing solenoid valve selects gear shift to move, simple control structure, reduces manufacture cost.
