Background technique
General commercial car gear box sub-case is mainly used in increasing output torque, because high moment of torsion, high load all exceeds the synchronous capacity of synchronizer, easily causes auxiliary box synchronizer to damage.Commercial car gearbox industry odd-side is generally taked pneumatic or Manual structure now, for the driver who drives over a long distance, be manually very disadvantageous, although pneumatic structure is more more convenient than manual shift, but pneumatic structure easily causes gas circuit to stop up, leak gas and the potential safety problems such as synchronizer early failue that cause are impacted in gearshift, because air pressure valve often needs to bear several atmospheric pressure, in long working process, reliability is often lower.
Summary of the invention
The utility model object is the deficiency existing for commercial car gear box sub-case Pneumatic shift, and a kind of electrically controlled gearbox odd-side that adopts motor speed-regulating and automatical control system mechanism to complete odd-side gearshift function is provided.
The utility model is achieved through the following technical solutions:
A kind of electrically controlled gearbox odd-side of the utility model, comprise fork shaft, shift fork, automatical control system mechanism, power input gear, power output gear, pto＝power take-off, tooth cover, jack shaft, shift fork is fixedly installed in fork shaft, it is characterized in that: automatical control system mechanism is directly installed on fork shaft, and control fork shaft axial motion, the integrated combination tooth of difference on power input gear and power output gear, power output gear empty set is on pto＝power take-off, the integrated power output shaft speed sensor of pto＝power take-off, tooth hub is directly mounted and fixed on pto＝power take-off, tooth cover is directly installed on tooth hub, the shift fork the other end embeds in tooth cover, constant mesh gear is fixedly mounted on jack shaft, and often mesh with power input gear, countershaft-gear is fixedly installed on jack shaft, and mesh with power output gear, speed-adjustable motor is installed on jack shaft, integrated jack shaft speed probe on jack shaft.
Fork shaft of the present utility model, power input gear, pto＝power take-off, jack shaft are fixed by bearing.
Fixing shift fork on the utility model fork shaft, fork shaft is connected with the control unit of automatical control system mechanism, putting into gear in advance in process, pto＝power take-off and jack shaft speed probe pass to information the control unit of automatical control system mechanism, the control unit of automatical control system mechanism by control speed-adjustable motor just/the reversion speed discrepancy that is coupled, thereby realize odd-side high/sky/low gear switches and hangs into gear function; The control unit of the utility model automatical control system mechanism detects put into gear in advance rotating speed and output shaft rotating speed when approximate, just controls fork shaft and moves vertically, until complete, hangs into gear.The utility model is owing to adopting motor speed-regulating and automatical control system mechanism to complete odd-side gearshift, rational in infrastructure, reliable performance.
