Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1 to Fig. 4, a kind of transmission reverse gear latching mechanism of the utility model, comprise the lock spring 2 that reverses gear be arranged in the housing 5 of speed changer, reverse gear lock pin 3, and gear level 4a or selector fork axle 4b; Wherein, the setting direction of gear level 4a or selector fork axle 4b is vertical with the setting direction of the lock pin 3 that reverses gear, and the circumference of gear level 4a or selector fork axle 4b offers the pin engagement groove 7 coordinated with the lock pin 3 that reverses gear; The lock pin 3 that reverses gear is installed with tutorial light 1 concentric that reverses gear of speed changer, the lock spring 2 that reverses gear is installed on the tutorial light 1 and reverse gear between lock pin 3 of reversing gear, when speed changer is neutral position state, the other end of the lock pin 3 that reverses gear is in the pin engagement groove 7 on the gear level 4a or selector fork axle 4b circumference that coordinate with it.
Further, the reverse gear centre of lock pin 3 is provided with the shaft shoulder, reverse gear one end of lock spring 2 is sleeved on and reverses gear on lock pin 3, and end face contacts with the shaft shoulder of the lock pin 3 that reverses gear, and the other end of locking spring 2 of reversing gear is sleeved on the tutorial light ejector pin 6 that is connected with the tutorial light 1 that reverses gear.
When speed changer is neutral position state, the lock spring 2 that reverses gear is in tensioning state, reverses gear between lock pin 3 with tutorial light ejector pin 6 and does not contact; When speed changer is for hanging reverse gear state, the lock spring 2 that reverses gear is in compressive state, reverse gear lock pin 3 jack-up tutorial light ejector pin 6, Qi Liang reverses gear indicator light switch, the state of putting into gear of instruction vehicle, and the other end of the lock pin 3 that reverses gear departs from the pin engagement groove 7 on the gear level 4a or selector fork axle 4b circumference that coordinate with it.Wherein, the pin engagement groove 7 in gear level 4a circumference is annular recess, and the pin engagement groove 7 in selector fork axle 4b circumference is independent groove or annular groove.
In order to further understand the utility model, now an explanation is done to its working procedure.
See Fig. 1 and Fig. 2, when this reverse gear latching mechanism is arranged on transmission control, the lock pin 3 that reverses gear matches with gear level 4a, under neutral position state, the lock pin 3 that reverses gear is in the pin engagement groove 7 in gear level 4a circumference, and wherein, pin engagement groove 7 is annular groove.
When needs are linked into and reverse gear, gear level 4a will move axially to the left, now gear level 4a needs overcome the lock spring 2 that reverses gear to the pressure of the lock pin 3 that reverses gear, the lock spring 2 that reverses gear is compressed the such height of the degree of depth of annular groove on gear level 4a, the lock pin 3 that can make to reverse gear climbs out of from the annular groove of gear level 4a, gear level 4a also needs the compressive force overcoming gear level balance spring simultaneously, could move axially to the left to be linked into and reverse gear.Meanwhile, jack-up tutorial light ejector pin 6, Qi Liang reverses gear the state of putting into gear of indicator light switch, instruction vehicle by the lock pin 3 that reverses gear climbing out of gear level 4a annular groove.Be linked in the process of reversing gear, driver by larger power, must play the effect of pointing out.
See Fig. 3 and Fig. 4, when this arrangement of mechanism is on selector fork axle, the lock pin 3 that reverses gear matches with selector fork axle 4b, and under neutral position state, the lock pin 3 that reverses gear is in the fit of selector fork axle 4b.
When needs are linked into and reverse gear, selector fork axle 4b will move axially to the left, now selector fork axle 4b needs overcome the lock spring 2 that reverses gear to the pressure of the lock pin 3 that reverses gear, the lock spring 2 that reverses gear is compressed the such height of the degree of depth of selector fork axle 4b upper groove, the lock pin 3 that can make to reverse gear climbs out of from the groove of selector fork axle 4b, could move axially to the left to be linked into and reverse gear.Meanwhile, jack-up tutorial light ejector pin 6, Qi Liang reverses gear the state of putting into gear of indicator light switch, instruction vehicle by the lock pin 3 that reverses gear climbing out of selector fork axle 4b groove.
