Interference fit is fixed.Its working principle is that pushing shaft to drive drag-line by handlebar, gearbox rocker arm is pushed by drag-line
To drive the switching realized between each gear.Mechanical shifting mechanism needs when having the following deficiencies: 1, installation first the bottom of by
Seat installation in the car, shell is being mounted on the base from top to bottom, since the lateral dimension of pedestal is larger and automobile is corresponding
Bore size will match with pedestal, i.e. the bore size of mounting seat is big；It 2, be first by fixed shell and bottom when needing repairing
The resilient key of seat is dismantled, and since resilient key and pedestal and shell are all interference fits, disassembly is extremely difficult, and elasticity of dismantling
Then the intracorporal components of shell could be repaired by shell from upper extraction after pin, very trouble, and dismantle elasticity
Pin easily causes coupling part between resilient key and shell, pedestal to damage；3, shaft is made of metal passes through interference fit
It is fixed with shell, disassembly shaft be easy to cause the damage of junction between shaft and shell；4, drag-line link position and castellated plates
All above shaft, movement travel is limited；5, structure is complicated, maintenance trouble for mechanical shifting mechanism, and manufacturing cost
It is high.Existing some middle-to-high end cars usually all use electronic type gearshift, and electronic type gearshift is using the electricity being electrically connected
Signal transduction mode is directly more shifted gears by way of distinguishing low and high level with hardwired fashion transmission electric current to receive signal
Position.Electronic type gearshift has the following deficiencies: that 1, electronic type gearshift electronic signal vulnerable to extraneous noise jamming, leads to letter
Number transmission is unstable, cannot hang up on file；2, electronic type gearshift easily burns internal circuit through vehicle body rush of current, leads to not
Signal is transmitted, cannot hang up on file.
