Description
Technical field
The invention belongs to electric automobile gear device gear handoff technique field.
Background technology
The working speed of motor in electric automobile is larger, and base and the electric automobile gear device of manual gear and AMT structures are being shifted gears
When splined shaft and gear to be engaged on splined shaft rotating speed differ greatly, stopper part can be exchanged and make to put into gear by relying solely on synchronizer
The comfortableness driven is influenceed into larger impact while also, the rotating speed of input shaft is pre-adjusted when the present invention passes through gearshift, makes flower
The rotating speed of key axle and gear to be engaged on splined shaft completes gear shift operation again when reaching consistent.
The content of the invention
Base splined shaft and gear to be engaged on splined shaft in gearshift with manual gear and the electric automobile gear device of AMT structures
Rotating speed differ greatly, gearshift by force can exchange stopper part and cause larger impact, and the present invention pre-adjusts defeated when passing through gearshift
Triggering dials gear signal and completes to shift gears again when entering the rotating speed of axle, the rotating speed of splined shaft and gear to be engaged on splined shaft is reached consistent
Operation, to realize the ride comfort of gearshift.
Technical scheme is as follows, and for this programme based on common manual speed changer and AMT structures, motor power passes through output
Axle, jackshaft, splined shaft are transferred to differential mechanism.In the moment of speed changer variable block, when speed changer is hung to high gear from low gear
The rotating speed of high gear gear on splined shaft is more than the rotating speed of splined shaft, spent when speed changer needs and hung from high gear to low gear
The rotating speed of low gear gear on key axle is less than the rotating speed of splined shaft.In order to realize the smooth-going of gearshift, treated in speed changer variable block
Meshing gear needs to reach consistent rotating speed with splined shaft.This programme is waited to nibble by increasing the method for a buncher to realize
Close the synchronization of gear rotational speed and spline rotating speed.
Buncher accesses input shaft, jackshaft in parallel or series, the speed governing when speed changer is hung to high gear from low gear
Motor incision energy recovering circuit, decline the rotating speed of gear to be engaged, when speed changer needs to hang to low gear from high gear
Buncher is switched to power output circuit, the rotating speed of gear to be engaged is increased.Due to gear to be engaged and spline during gearshift
The rotating speed of axle is all dynamic variable, is only determined that Tong Walk time points could operate selector fork.Determine Tong Walk time points
Method is as follows, and two speed probes, the high gear tooth on low gear gear and splined shaft on splined shaft are installed on splined shaft
One speed probe of each installation is taken turns, each speed probe respectively connects the revolution counter of a same specification same parameter.Splined shaft is corresponding
A revolution counter revolution counter corresponding with low gear gear surface, face-to-face side by side installation, installation effect is two
Pointer rotates around same axle.The table of another revolution counter revolution counter corresponding with high gear gear corresponding to splined shaft
Face, face-to-face installation side by side, installation effect are that two pointers rotate around same axle.Leading for protrusion is filled on each pointer
Electric contact, when splined shaft is synchronized with low gear gear on splined shaft, the conductive contact of two pointers protrusions is collided on revolution counter
The switch K1 of a conducting is formed, two pointers protrude on revolution counter when the high gear gear on splined shaft and splined shaft is synchronized
Conductive contact collide to be formed another conducting switch K2.
Increase a signal source, two relays in automobile circuit.When changing to low gear by high gear, rotating speed corresponding to splined shaft
Table is always maintained at on-state, and a revolution counter corresponding to low gear gear only changes to the mistake of low gear in gearshift, by high gear
Revolution counter is just connected when neutral is pushed in journey.When changing to high gear by low gear, a revolution counter is protected always corresponding to high gear gear
On-state is held, revolution counter is just connected when revolution counter pushes neutral corresponding to splined shaft during changing to high gear by low gear.Flower
The conductive contact of two revolution speed meter pointer protrusions connects signal source corresponding to key axle, and revolution speed meter pointer corresponding to low gear gear protrudes
Conductive contact be respectively connected to the current input terminal of relay and car running computer dials the input of gear trigger signal, high gear
The conductive contact that revolution speed meter pointer corresponding to gear protrudes is respectively connected to the current input terminal and car running computer of another relay
The input of gear trigger signal is dialled, access buncher electricity of being connected again after normal-closed end parallel connection when two relay no currents input
Road.
Electric automobile gear device is changed to by low gear and first pushes neutral by low gear during high gear, now corresponding to splined shaft
Revolution counter is connected, pointer starts to rotate, and subsequent [using delay circuit] buncher incision energy recovering circuit makes high gear tooth
Revolution speed meter pointer corresponding to wheel is adjusted back, and when splined shaft and synchronized high gear gear, two conductive contacts are collided, connected, now signal
Source implements to dial to keep off operating by two conductive contacts triggering car running computer all the way pushes high gear, another way one relay of access by neutral
The current input terminal of device disconnects buncher circuit, and revolution speed meter pointer corresponding to splined shaft returns zero speed position after leaving neutral.
Electric automobile gear device is changed to by high gear and first pushes neutral by high gear during low gear, now low gear gear mesh
The revolution counter answered is connected, pointer starts to rotate while buncher is switched to power output circuit, when splined shaft and low gear tooth
Two conductive contacts are collided, connected when taking turns synchronized, and now signal source triggers car running computer by two conductive contacts all the way and implements to dial gear
Operation pushes low gear by neutral, the current input terminal of another way one relay of access disconnects buncher circuit, leaves sky
Revolution speed meter pointer corresponding to low gear gear returns zero speed position after gear.
