Abstract

The invention relates to an electric motor coach mechanical automatic transmission gear shift mechanism which comprises more than one gear shift motor, a roller cylinder screw rod, a gear shift dialing head, a gear shift shaft, a guide block and a shifting fork, gear shift sleeve cylinders and gear shift gears, wherein the roller cylinder screw rod is rotated by the driving of the gear shifting motors; the gear shift dialing head is screwed to the roller cylinder screw rod in a threaded manner; the gear shift shaft is arranged in parallel to the roller cylinder screw rod; the guide block and the shifting fork slidingly penetrate through the gear shift shaft, the guide block and the gear shift dialing head are fixedly connected, and the shifting fork and the guide block are fixedly connected; a gear shift sleeve cylinder is movably arranged in the shifting fork through a bearing; a gear shift sleeve cylinder is connected to an output shaft through a key; the gear shift gears are movably sleeved on two sides of the gear shift sleeve cylinder on the output shaft; and the gear shift sleeve cylinder and the gear shift gears at two sides of the gear shift sleeve cylinder are sleeved and connected axially along the output shaft or in a disjointed and separated state. The gear shifting gears corresponding to the gear shift sleeve cylinder in the shifting fork are joined, thus the input motive power of the electric motor is output by the gear shift gears through gear shifting, and the electric motor coach mechanical automatic transmission gear shift mechanism is accurate in electric motor signals, reliable in gear shift performance, and stable to use.

Description

A kind of electric motor coach mechanical automatic speed-changing case gearshift mechanism
Technical field
The present invention relates to a kind of electric motor coach mechanical automatic speed-changing case gearshift mechanism.
Background technique
Original gearshift mechanism of electric motor coach mechanical automatic speed-changing case is: servovalve → cylinder (oil hydraulic cylinder) → piston rod → shift fork → select gear shift; Because the pressure of source of the gas, hydraulic power, the influence of shift pattern uncertain factor; The output signal of handling through TCU is inaccurate; Thereby cause gear shift undesirable, stability in use can be poor.
Summary of the invention
To deficiency of the prior art, the present invention provides the electric motor coach mechanical automatic speed-changing case gearshift mechanism that a kind of shift property is reliable, use is stable.
The present invention adopts following technological scheme: a kind of electric motor coach mechanical automatic speed-changing case gearshift mechanism, and its technical characterstic is to comprise: an above gear shifting motor; Ball screw by the gear shifting motor rotary driving; Screw thread is rotatably connected in the gear shift shifting block on the ball screw; The shift shaft that laterally arranges with ball screw; Slip is connected to guide block and the shift fork on the shift shaft, and guide block is fixedly connected with the gear shift shifting block, and shift fork is fixedly connected with guide block; Gear shift sleeve in bearing is movably set in shift fork; Be connected in the gear shift sleeve on the output shaft through key; The change gear of pivot bush unit gear shift sleeve both sides on output shaft; Gear shift sleeve and the change gear of its both sides be along the axial fit of output shaft be connected or disengagement side from state.
The present invention has following beneficial effect: when the gear shift demand, through TCU shift signal is sent to gear shifting motor, gear shifting motor drives the ball screw rotation; Shifting block is limited in shift shaft by guide block, and shifting block drives guide block and on shift shaft, slides being subjected to displacement on the ball screw, and guide block drives shift fork and moves; The change gear corresponding respectively at gear shift sleeve in the shift fork engages; Make motor input power through change gear gear shift output, its electromotive signal is accurate, and shift property is reliable, use is stable.
