The utility model can by the operation of operator's compartment control it with the disengaging and the engagement of gearbox gear, make operating personal can judge clearly that being in transmission shaft of power takeoff this moment mesh or disengaged position by neutral switch.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: this has the Automatic Transmission power takeoff of neutral switch, comprise that transmission shaft 1 right part turret is located at the output flange 3 in the housing 2, be with spline housing 4 on the output flange 3 with its commentaries on classics sliding block joint, described spline housing 4 intermittently meshes with the right part of transmission shaft 2, in the slide opening 5 of housing 2, slidely connect piston 7, on piston 7, be fixed with the pushing bar 6 that makes spline housing 4 and transmission shaft 2 mesh or separate, the slide opening 5 of the right part of piston 7 and housing 2 forms airtight cavity, on housing 2, be provided with the inlet suction port 13 that is communicated with this airtight cavity, between the left side of piston 7 section and housing 2 inwalls, has retracing spring 8, be provided with neutral position switch 12 on housing 2, the intermittent insertion in the housing 2 of the inserted link of described neutral position switch 12 stops piston 7.
Offer installing blind 16 at piston 7 to the right from its left side, described retracing spring 8 right sections embed in this installing blind 16, offer through hole on retracing spring 8 left part corresponding shell 2, at this through-hole wall spring perch 9 is installed, described retracing spring 8 left parts are against on the spring perch 9.
Through-hole wall at spring perch 9 left ends is equipped with air inlet blockage body 10.
The left end of output flange 3 embeds in the blind hole of offering transmission shaft 2 right parts, has needle bearing 15 between output flange 3 and transmission shaft 2.
Spline housing 4 outer walls are provided with circumferential installation groove 14, and described pushing bar 6 bottoms embed in this installation groove 14.
Housing 2 outsides are stretched out in the right part of output flange 3.
Working process of the present utility model is as follows:
With the dumping car is example, during walking, transmission shaft 2 is in disengaged position with output flange 3, when needing the lifting compartment, feed pressurized air in the power takeoff under operating personal control, the application force that this moment, piston 7 overcame retracing spring 8 under compressed-air actuated effect is subjected to displacement, pushing bar 6 above driving is subjected to displacement simultaneously, thereby stir spline housing 4 and transmission shaft 2 engagements, drive output flange 3 and rotate output torque.
In the process that pushing bar 6 is subjected to displacement, pushing bar 6 one ends are pressed down neutral switch 12, and the loop under the normally off is disconnected, and this signal passes in the operator's compartment, and what operating personal can clearly be judged power takeoff this moment is in engagement with transmission shaft.
