Description
Technical field
The present invention relates to a kind of speed changer, be specifically related to a kind of retarder that is used for heavy vehicle.
Background technique
The effect of speed reducer mainly is the output that reduces the output of motor and improve motor.And the rotating speed of motor or diesel engine generally is discrepant with our rotating speed of needs, and output speed is all very high, for rotating speed or the torque that needing to obtain, need the rotating speed of power source be reduced.
Speed reducer is as afterbody speed reducer in the power train, is used for further reducing rotating speed, increases output shaft torque.Original endless-track vehicle side speed reducer adopts the one-level side speed reducer, and the reduction speed ratio that it is realized is less, can not satisfy the requirement of several work function large torque outputs such as existing vehicle implementation soil-shifting, lifting, excavation.
Summary of the invention
Technical problem to be solved by this invention is the retarder that is used for heavy vehicle, and this retarder adopts two reduction gear, and rotating ratio is big, and the output torque is big.
Technological scheme of the present invention: a kind of retarder that is used for heavy vehicle, it comprises driving shaft, driven gear, gear ring, gear-box, gear box cover, driving gear, planetary pinion, planetary frame, planet pin, fixedly plug screw, conehead screw rod and driven axle, driving shaft is provided with driving gear; One end of driving shaft is arranged on the gear-box, and the other end is arranged on the gear box cover, and driven axle is arranged on the gear box cover; Driven gear is through fixedly plug screw, conehead screw rod are arranged on the driven axle; Planetary frame is connected with driven axle, and planetary frame is provided with planet pin, and planetary pinion is arranged on the planet pin; Driven gear meshes with driving gear, planetary pinion respectively; Gear box cover is arranged on the gear-box, and gear ring is arranged on the gear box cover, gear ring and planetary pinion engagement.
Described gear-box is provided with breathing pipe, oil filler, fuel outlet, is respectively arranged with plug screw on oil filler and the fuel outlet.
The present invention compared with prior art has following beneficial effect: 1, the present invention adopts the two reduction gear that outer gearing of one-level dead axle and the combination of one-level Gear Planet Transmission form; Reduction speed ratio is big; The output torque is big, can satisfy the requirement of several work functions such as soil-shifting, lifting, excavation.2, light weight, compact structure, anufacturability is good.3, repairing, maintenance, easy maintenance.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
A kind of retarder that is used for heavy vehicle, as shown in Figure 1, it comprises driving shaft 1, driven gear 2, gear ring 3, gear-box 4, gear box cover 5, driving gear 6, planetary pinion 7, planetary frame 8, planet pin 9, fixedly plug screw 10, conehead screw rod 11 and driven axle 12; Driving shaft 1 is provided with driving gear 6; One end of driving shaft 1 is arranged on the gear-box 4, and the other end is arranged on the gear box cover 5, and driven axle 12 is arranged on the gear box cover 5; Driven gear 2 is through fixedly plug screw 10, conehead screw rod 11 are arranged on the driven axle 12; Planetary frame 8 is connected with driven axle 12, and planetary frame 8 is provided with planet pin 9, and planetary pinion 7 is arranged on the planet pin 9; Driven gear 2 meshes with driving gear 6, planetary pinion 7 respectively; Gear box cover 5 is arranged on the gear-box 4, and gear ring 3 is arranged on the gear box cover 5, gear ring 3 and planetary pinion 7 engagements.
Described gear-box 4 is provided with breathing pipe, oil filler, fuel outlet, is respectively arranged with plug screw on oil filler and the fuel outlet.The setting of breathing pipe makes the inside and outside air ventilation of gear-box, avoids because of the rising of the pressure in case leakage of oil.
Claims (2)
1. retarder that is used for heavy vehicle; It comprises driving shaft (1), driven gear (2), gear ring (3), gear-box (4), gear box cover (5), driving gear (6), planetary pinion (7), planetary frame (8), planet pin (9), fixedly plug screw (10), conehead screw rod (11) and driven axle (12); It is characterized in that driving shaft (1) is provided with driving gear (6); One end of driving shaft (1) is arranged on the gear-box (4), and the other end is arranged on the gear box cover (5), and driven axle (12) is arranged on the gear box cover (5); Driven gear (2) is through fixedly plug screw (10), conehead screw rod (11) are arranged on the driven axle (12); Planetary frame (8) is connected with driven axle (12), and planetary frame (8) is provided with planet pin (9), and planetary pinion (7) is arranged on the planet pin (9); Driven gear (2) meshes with driving gear (6), planetary pinion (7) respectively; Gear box cover (5) is arranged on the gear-box (4), and gear ring (3) is arranged on the gear box cover (5), gear ring (3) and planetary pinion (7) engagement.
