Summary of the invention
The differential mechanism that the purpose of this utility model is design for the deficiency that solves above-mentioned technology a kind of simple and compact for structure, easy for installation, transmission is stable.
the differential mechanism that the utility model is designed, comprise the differential casing, be provided with driven gear in described differential casing, by two horizontal umbrella gear and two umbrella gear groups that vertical umbrella gear consists of, a long output shaft and a short output shaft, described long output shaft is connected with two vertical umbrella gear respectively with short output shaft, described driven gear is connected with the umbrella gear group, also be provided with into the powershift gear axle in described differential casing, describedly enter powershift gear axle two ends and be arranged in the differential casing by bearing and the end that enters the powershift gear axle is provided with connector, described driven gear with enter the powershift gear axle and be meshed.
As preferably:
Describedly enter the integral structure that the powershift gear axle is comprised of gear shaft, bulge loop, cylindrical section and linkage section, described gear shaft front end has one section undergauge section, and described bulge loop, cylindrical section and linkage section are positioned at the rear end of gear shaft successively; Described linkage section is provided with a groove;
Described connector is the plastic cement connector;
The differential mechanism that the utility model is designed, it enters the powershift gear axle and is meshed with driven gear, enter the powershift gear axle and drive driven gear as the power of input and rotate, in the mixing ratio prior art of gear shaft and gear the cooperation of bevel gear more stable, can effectively guarantee the transmission effect; The structure that enters in addition the powershift gear axle is more long and narrow than the existing power of entering bevel gear, and structure is more compact; Moreover enter the end that powershift gear axle two ends are arranged on the differential casing by bearing and enter the powershift gear axle and be provided with connector, install more convenient.Therefore this differential mechanism practicability is stronger.
Description of drawings
Fig. 1 is embodiment 1 structural representation;
Fig. 2 is the structural representation that embodiment 2 enters the powershift gear axle;
In figure: gear shaft 1, bulge loop 2, cylindrical section 3, linkage section 4, groove 5, undergauge section 6, differential casing 7, driven gear 8, laterally umbrella gear 9, vertically umbrella gear 10, long output shaft 11, short output shaft 12, umbrella gear group 13, enter powershift gear axle 14, connector 15, bearing 16.
Embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
as shown in Figure 1, the described differential mechanism of the present embodiment, comprise differential casing 7, be provided with driven gear 8 in described differential casing 7, by two horizontal umbrella gear 9 and two umbrella gear groups 13 that vertical umbrella gear 10 consists of, a long output shaft 11 and a short output shaft 12, described long output shaft 11 is connected with two vertical umbrella gear 10 respectively with short output shaft 12, described driven gear 8 is connected with umbrella gear group 13, also be provided with into powershift gear axle 14 in described differential casing 7, describedly enter powershift gear axle 14 two ends and be arranged in differential casing 7 by bearing 16 and the end that enters powershift gear axle 14 is provided with connector 15, described driven gear 8 with enter powershift gear axle 14 and be meshed.Described connector 15 is plastic cement connectors.
The described differential mechanism of the present embodiment, it enters powershift gear axle 14 and is meshed with driven gear 8, enter powershift gear axle 14 and drive driven gear 8 as the power of input and rotate, in the mixing ratio prior art of gear shaft and gear the cooperation of bevel gear more stable, can effectively guarantee the transmission effect; The structure that enters in addition powershift gear axle 14 is more long and narrow than the existing power of entering bevel gear, and structure is more compact; Moreover enter the end that powershift gear axle 14 two ends are arranged on the differential casing by bearing 16 and enter powershift gear axle 14 and be provided with connector 15, install more convenient.Therefore this differential mechanism practicability is stronger.
Embodiment 2:
