Description
One technical field
The utility model relates to a kind of vehicular transmission gearshift, a kind of especially automobile-used power split automatic transmission gearshift.
Two background techniquies
Gearshift is used to realize the switching between the different gears of speed changer.Except that stepless speed variator, it is one of vitals in all kinds of speed changers.By the manual operation clutch operating, shift gears during conventional mechanical formula shift of transmission, adopt synchronizer to reduce to impact, make gearshift steady, light to manually.Gearshift in the automatic transmission is generally electricity-liquid form, by executive components such as ECU (Electrical Control Unit) control electronic valves, is driven related elements actions such as clutch, break by hydraulic oil, realizes gearshift.Though realized self shifter in the automatic transmission, the structure relative complex, the manufacture cost height, difficulty is applied to economy car and microbus.
Three summary of the invention
The purpose of this utility model is to provide a kind of satisfy automatically controlled automatic switchover gear, shift process is steady, simple and reliable for structure, price performance is high automobile-used power split automatic transmission gearshift.
The technical solution that realizes the utility model purpose is: a kind of automobile-used power split automatic transmission gearshift, it comprises synchronizer, motor, casing, bearing support is set in the casing, bearing is set in the bearing support, the transmission part that is arranged in the bearing is connected with motor, and shift fork and transmission part are connected, and the bayonet socket of shift fork is arranged in the annular groove of synchronizer, sensor stand also is set in the casing and sensor is set thereon, the hall sensing sheet is set on the transmission nut relative with sensor.
The principle of model utility is: the motion by control synchro realizes gearshift, and motor is given the gearshift transmission part by the Placement of transmission of power with transmission of power, the rotating power of motor is converted into the selector fork straight line motion realizes gearshift.Bearing support is by being bolted on the casing, pressing bearing in the bearing support, bearings gearshift transmission part, shift fork is fixed on the gearshift transmission part, the head of shift fork is stuck in the annular groove of synchronizer, the gearshift transmission part is converted into the straight line motion of shift fork with rotatablely moving of motor, promotes synchronizer and finishes gearshift.Sensor stand is fastened in the casing by bolt, and the head of sensor is the tapped hole connection of outside thread with sensor stand.The hall sensing sheet is bonded on the gearshift transmission part, and sensor and hall sensing sheet are finished gear and judged.Clutch adopts automatically controlled magnetic powder clutch.
The utility model compared with prior art, its remarkable advantage is: this gearshift is applied to realize computer-controlled self shifter in the automobile-used power split automatic transmission.Advantages such as not only convenient the driving helps the raising of vehicle dynamic quality, Economy etc., and possess high price performance, and structure is uncomplicated, and manufacture cost is lower.Obtain applying with the vitals that improves automotive performance as a kind of electromechanical integration new product for automobile-used power split automatic transmission and play an important role.
Four description of drawings
