Abstract
The utility model relates to a creeper gear structure for a tractor, which adopts a double-stage planetary mechanism for speed reduction and mainly comprises a first-stage planetary mechanism and a second-stage planetary mechanism; the first-stage planetary mechanism and the second-stage planetary mechanism are sequentially arranged; one end of the first-stage planetary mechanism is connected with a gearbox of the tractor by an input shaft, and one end of the second-stage planetary mechanism is connected with a rear axle of the tractor by an output shaft; and the axes of the input shaft and the output shaft are on the same straight line. By adopting the arrangement mode, the transmission route is clear, the structure is compact, the power of the gearbox of the tractor can be transmitted to the rear axle of the tractor, and a direct gear and a creeper gear are realized. By adopting the double-stage planetary mechanism for speed reduction, the larger transmission ratio of the creeper gear can be obtained, and the lowest creeper tractor speed can reach 0.24km/h. The gear parameters of the two stages of planetary mechanisms are the same, planetary wheels and planetary wheel shafts are universal, gear rings form a whole, the variety and the number of parts are reduced, and the production cost is lowered.
Description
Technical field
The utility model belongs to the tractor field, relates to a kind of used with tractor retaining structure of creeping.
Background technique
At present, in the large and middle tractor product that China produces, the tractor negligible amounts that configuration is creeped and kept off, and the retaining of creeping that is disposed two-stage external gear pump retarder or the single-stage planetary retarders of adopting more, velocity ratio is little, and it is big to take structure space, and the minimum speed of a motor vehicle is generally greater than 0.3km/h.Along with the continuous development in domestic and international tractor market, the user is increasing to the creep tractor demand of retaining function of configuration, requires the minimum speed of a motor vehicle to be lower than 0.3km/h, to satisfy the operation needs.Therefore the used with tractor that is necessary to develop a kind of big speed ratio, the compact structure retaining structure of creeping is to satisfy tractor user's usage requirement.
The model utility content
The purpose of this utility model is to provide the used with tractor of a kind of compact structure, the big speed ratio retaining structure of creeping, to satisfy tractor user's usage requirement.
The technical solution of the utility model is: a kind of used with tractor retaining structure of creeping, and adopt the twin-stage planetary mechanism to slow down, mainly comprise first order planetary mechanism, second level planetary mechanism; First order planetary mechanism and second level planetary mechanism are arranged in order; Wherein first order planetary mechanism one end links to each other with gear box of tractor by input shaft, and planetary mechanism one end in the second level links to each other with tractor rear axle by output shaft; The axle center of input shaft and output shaft is on same straight line.
In the first order planetary mechanism, the one-level sun gear is installed on the input shaft by spline, and one-level sun gear and uniform three one-level planet wheels that are installed on the primary planet carrier are meshing with each other simultaneously, and three one-level planet wheels and gear ring are meshing with each other simultaneously; Gear ring is fixed on the gear box casing.
In the planetary mechanism of the second level, secondary sun gear and primary planet carrier are an integral body, and secondary sun gear and uniform three secondary planet wheels that are installed on the secondary planet frame are meshing with each other simultaneously, and three secondary planet wheels are meshing with each other simultaneously with gear ring.
Sliding gear collar is installed on the output shaft by spline, and can horizontally slip vertically.
The utility model can reach following good effect: tractor creep the retaining structure adopt above-mentioned arrangement, drive path is clear, compact structure can realize directly keeping off and creeping retaining with gear box of tractor power to the tractor rear axle transmission.Adopt the twin-stage planetary mechanism to slow down, can obtain the bigger retaining velocity ratio of creeping, minimum creeper-traveler scooter 0.24km/h.The gear parameter of two-stage planetary mechanism is identical, and planet wheel, planet wheel shaft are general, and gear ring is an integral body, has reduced part kind and quantity, has reduced cost of production.
Description of drawings
Accompanying drawing is creeped for the utility model used with tractor and is kept off the structural representation of structure.
Embodiment
Below by accompanying drawing the utility model is further described, as shown in drawings, this kind used with tractor retaining structure of creeping mainly comprises first order planetary mechanism 12, second level planetary mechanism 11.First order planetary mechanism 12 and second level planetary mechanism 11 are arranged in order.Wherein first order planetary mechanism 12 1 ends link to each other with gear box of tractor 14 by input shaft 13, and planetary mechanism 11 1 ends in the second level link to each other with tractor rear axle 9 by output shaft 10.The axle center of input shaft 13 and output shaft 9 is on same straight line.
In the first order planetary mechanism 12, one-level sun gear 1 is installed on the input shaft 13 by spline, and one-level sun gear 1 is meshing with each other simultaneously with uniform three one-level planet wheels 2 that are installed on the primary planet carrier 3, and three one-level planet wheels 2 are meshing with each other simultaneously with gear ring 4.Gear ring 4 is fixed on gearbox 14 housings and can not rotates.
In the second level planetary mechanism 11, secondary sun gear 6 is an integral body with primary planet carrier 3, secondary sun gear 6 is meshing with each other simultaneously with uniform three secondary planet wheels 5 that are installed on the secondary planet frame 7, planet wheel 5 is consistent with planet wheel 2 gear parameters, secondary planet wheel 5 and one-level planet wheel 2 parts are general, and three secondary planet wheels 5 are meshing with each other simultaneously with gear ring 4.Sliding gear collar 8 is installed on the output shaft 10 by spline, and can horizontally slip vertically and be connected tooth and be meshed with input shaft 13 or with spline on the secondary planet frame 7 selecting respectively.
Tractor dynamic power is as follows through the used with tractor retaining structure bang path of creeping:
Direct retaining: sliding gear collar 8 slides left, is connected tooth with spline on the input shaft 13 and meshes.Power is by gear box of tractor 14 → input shaft 13 → sliding gear collar 8 → output shaft 10 → tractor rear axle 9.
The retaining of creeping: sliding gear collar 8 slides to the right, is connected the tooth engagement with spline on the secondary planet frame 7.Power is by gear box of tractor 14 → input shaft 13 → one-level sun gear 1 → one-level planet wheel 2 → primary planet carrier 3 → secondary sun gear 6 → secondary planet wheel 5 → secondary planet frame 7 → sliding gear collar 8 → output shaft 10 → tractor rear axle 9.
This shows that tractor is creeped and kept off and the power of gear box of tractor 14 can be transmitted to tractor rear axle 9, realizes directly keeping off or creeping retaining.
