Summary of the invention
The objective of the invention is the problems referred to above, provide a kind of gear selecting smoothness, electric-controlled mechanical simple in structure to rotate the gear selecting actuator of gearbox at the prior art existence.
Purpose of the present invention can realize by following technical proposal: a kind of gear selecting actuator of electrical control automatic manual transmission case, be arranged at the gear level place of automatic transmission case, it is characterized in that, this mechanism comprises some gearshift parts between adjacent two gear levels, described gearshift part is two oil cylinders and the piston rod between two oil cylinders, the two ends of piston rod lay respectively in two above-mentioned oil cylinders and have the shift fork that can stir gear level on piston rods, and above-mentioned some gearshift parts link to each other with hydraulic pipe line.
Hydraulic pipe line is controlled one of them oil cylinder and is in the punching press state, when other oil cylinder all is in the pressure release state, the shift fork of one of them gearshift part moves to pressure release oil cylinder place, and the shift fork extruding gear level after moving makes automatic transmission case realize gearshift by the gear level after moving.
That is to say that having only one of them oil cylinder in the shift process is to be in the pressurising state, other some oil cylinders all are in the pressure release state.Different oil cylinder pressurisings has realized different gear level actions, thereby reaches the purpose of speed changer gear selecting.
In the gear selecting actuator of above-mentioned electrical control automatic manual transmission case, described gearshift part also comprises a lock pin that is positioned on the gearbox, described lock pin place be provided with the locking spring and under the elastic force effect of locking spring lock pin be embedded on the shift fork.
When two oil cylinders in the same gearshift part all were in the pressure release state, this moment, lock pin was embedded on the shift fork under the elastic force effect of locking spring, and shift fork is formed the location.
In the gear selecting actuator of above-mentioned electrical control automatic manual transmission case, have positioning recess on the described shift fork, and above-mentioned lock pin can be embedded in the positioning recess place under the effect of locking spring force when shift fork breaks away from adjacent shift level.
Lock pin makes more firm the forming with shift fork of lock pin locate when embedding positioning recess.
In the gear selecting actuator of above-mentioned electrical control automatic manual transmission case, be provided with guiding element in the described oil cylinder and guiding element is enclosed within on the piston rod.
Owing to have the gap between piston rod and the oil cylinder inner wall, can make piston rod straight mobile by guiding element, avoid bias effect to use.
In the gear selecting actuator of above-mentioned electrical control automatic manual transmission case, also be provided with Returnning spring in the described oil cylinder, have the trend of disengaging shift level at the elastic force effect lower shift fork of Returnning spring.
After shift fork moved, one of them in-oil cylinder Returnning spring was squeezed.The Returnning spring auxiliary piston rod resets and is convenient to shift gears next time when switching gear.
In the gear selecting actuator of above-mentioned electrical control automatic manual transmission case, described guiding element is to the bearing that is set in the place, piston rod end along piston rod.
Some bearings lead to the mobile of piston rod by bearing along piston rod to cover thereon.
In the gear selecting actuator of above-mentioned electrical control automatic manual transmission case, described guiding element is to the annular collar that is set in the piston rod end along piston rod.
The annular collar outside and the interior side contacts of oil cylinder, annular collar is inboard to be contacted with piston rod.By such structure the mobile of piston rod led.
Compared with prior art, the gear selecting actuator of this electrical control automatic manual transmission case is some gearshift parts of being located between adjacent two gear levels, and each gearshift part is independent and all by the hydraulic pipe line centralized control.Do not have the gear selecting process during gearshift, the time of power interruption when greatly reducing the gearshift of electrical control automatic manual transmission case, make gearshift quick, stable.
Simultaneously, this mechanism is owing to only be made up of piston rod, oil cylinder and lock pin etc., so structure is also fairly simple, has higher utility.
