Wherein, be circumferentially provided with bull gear at cylinder 5 cavity walls with driven wheel relevant position, bull gear is meshed with driven wheel.
Wherein, described driven wheel stretches out from the left end of cylinder 5, left bracket 2 with leg on be provided with gear hobbing, driven wheel is meshed with gear hobbing.
Wherein, described cylinder 5 is by be erected at the support of bearing on left support abutment 3 and right support abutment 8 and can to rotate relative to left support abutment 3 and right support abutment 8.
The technological progress that the present invention obtains is:
1, the present invention is by being installed on power set in cylinder, the pitching of communication antenna is driven and becomes a kind of horizontal drive pattern, cylinder rotates, drive communication antenna rotates, break longitudinal transmission mode that communication antenna drive unit is traditional, achieve the low dwarfing of communication antenna drive unit, to ensure that less than 2.4 meters communication antennas use on roof.
2, between cylinder and stationary magazine creel, be provided with clutch shaft bearing, make relation therebetween be not only the relation of relative motion, and stationary magazine creel also serve supporting role to cylinder, thus product structure is simplified.
3, at the left and right bearing at cylinder two ends, for ensureing the drive unit of cylinder rotation and resting barrel inside, its height only can ensure that cylinder does pitch rotation, ensures the highly low dwarfing of antenna collection with this.
3, solve the entrucking height problem of less than 2.4 meters vehicle-carrying communication antennas, high accuracy planetary reduction gear and motor are installed in cylinder, ensure that less than 2.4 meters car antennas can be installed on roof.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details:
Embodiment one,
As shown in Figure 1 and Figure 2, a kind of pitch drive for vehicle-carrying communication antenna, comprise cylinder 5, described cylinder 5 by be erected at the support of clutch shaft bearing 1 on left support abutment 3 and right support abutment 8 and can to rotate relative to left support abutment 3 and right support abutment 8, the both ends of cylinder 5 be circumferentially fixedly installed left bracket 2 for fixedly mounting antenna 11 and right axle seat 10 respectively; Be provided with stationary magazine creel 6 at the cylinder chamber internal frame of cylinder 5, the cylinder cavity wall of cylinder 5 is connected by the second bearing 9 with between stationary magazine creel 6, and one end of stationary magazine creel 6 is fixed by connector and right support abutment 8; The power set rotated for head roll 5 are arranged in the cylinder chamber of stationary magazine creel 6.
Described power set comprise motor 7 and planetary reduction gear 4, motor 7 and planetary reduction gear 4 are all fixed on the cylinder cavity wall of stationary magazine creel 6, the power output shaft of its motor connects the power input shaft of planetary reduction gear 4, the power output shaft of planetary reduction gear 4 is connected with driven wheel, circumferentially be provided with bull gear at cylinder 5 cavity walls with driven wheel relevant position, the bull gear driving gear drives cylinder 5 that is meshed with driven wheel rotates.
As second embodiment, driven wheel can be replaced with friction pulley 12, circumferentially just large bull gear can not be set like this at cylinder 5 cavity walls, the function that head roll 5 carries out rotating can be played equally.
As the 3rd embodiment, described driven wheel stretches out from the left end of cylinder 5, left bracket 2 with leg on be provided with gear hobbing, driven wheel is meshed with gear hobbing, thus head roll 5 rotates.
In actual use, need the good drum-type pitch drive of first mounting and adjusting, then install and adjust antenna 11.Concrete assembling process is as follows:
