Present automatic transmission mainly contains hydraulic automatic speed variator (AT), CVT (continuously variable transmission) (CVT) and electric control mechanical type automatic speed variator (AMT).Do not cut off power shfit though AT has, starting and gear shift are steady, and external loading is had the advantage of adaptive performance, and its efficient is low, complex structure, cost height.The smooth variation of CVT speed ratio, stepless transmitting torque, acceleration is good, the fuel economy height, but its starting performance is poor, and driving belt damages easily, can not bear bigger load.AMT transforms on existing mechanical speed changer basis, original manual control mechanism is made into the micro motor control action, it has kept the advantage that transmission efficiency height, the cost of manual transmission is low, simple in structure and be easy to make, the advantage that in handiness, has possessed simultaneously some AT again, therefore, the cost performance of AMT is the highest, and it will be an important directions of automatic transmission development.Existing AMT gear-selecting and shifting executing mechanism all is to realize selecting the powerdriven of gear shift action by worm couple or gear pair basically.The worm and gear auxiliary driving has advantages such as stable working, noise is low, velocity ratio is big, but shortcomings such as its simultaneously also efficient low, easy heating.The gear pair transmission has advantages such as efficient height, transmitted power scope be big, but gear-driven noise, vibration, that impact is influenced by the Gear Processing precision is bigger.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of transmission efficiency height at above-mentioned the deficiencies in the prior art, and noise is low, is difficult for the ball wire rod-type gear-selecting and shifting executing mechanism of heating and safety and stability.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of ball wire rod-type gear-selecting and shifting executing mechanism, comprise the gear selecting motor, gear shifting motor and select shifting implementation device, describedly select shifting implementation device to comprise to select shift shaft, select reverse shift fork and gear shift drive block, the gear shift drive block is fixedly mounted on and selects on the shift shaft, select reverse shift fork to be slidingly mounted on and select on the shift shaft, the gear selecting motor selects reverse shift fork along selecting the axial moving linearly of shift shaft, gear shifting motor to be connected with the gear shift drive block by the gear shift ball wire bar pair and driving the gear shift drive block and to select reverse shift fork be axis swing to select shift shaft by the gear selecting ball wire bar pair with selecting reverse shift fork to be connected and drive.This ball wire rod-type gear-selecting and shifting executing mechanism adopts ball wire bar pair as transmission device, so this ball wire rod-type gear-selecting and shifting executing mechanism transmission efficiency height, stable working, heat generation rate are low, can also hi-Fix.
As the further improved technological scheme of the utility model, the screw rod of described gear selecting ball wire bar pair is installed on the gear selecting electric machine main shaft, and the nut of gear selecting ball wire bar pair is fixedly installed on and selects on the reverse shift fork; The screw rod of described gear shift ball wire bar pair is installed on the gear shifting motor main shaft, and the nut of gear shift ball wire bar pair is fixedly connected on the gear shift drive block.The effect of gear shift ball wire bar pair is to change into straight line motion with rotatablely moving, and has very little surface friction drag.
The utility model has made full use of the transmission efficiency height of ball wire bar pair, stable working, heat generation rate is low, advantage such as hi-Fix and reversibility, reduced the power consumption of vehicle when implementing to select the gear shift action, the transmission power scope of ball screw is big simultaneously, gear-selecting and shifting executing mechanism is applicable in multi-vehicle-type more or the different condition of road surface, also compacter on the spatial structure, and, because ball screw adjutant power and move through the free rolling ball and between screw mandrel and nut, transmit, replace sliding friction, the working life that can improve gear-selecting and shifting executing mechanism well with rolling friction.
