Abstract
The utility model relates to a double brake agricultural booster tricycle, the rear end of a tricycle frame of the tricycle is connected with a carriage and a rear axle; the rear shaft is connected with two flower-drums; two flower-drums are respectively connected with a rear wheel. Two plate springs are connected with the bottom of the carriage; two plate springs are respectively connected with plate spring seats; the plate spring seat are connected with the rear shaft. The utility model is characterized in that the end faces of plate spring seat are connected with brake mechanisms; the brake mechanisms can be matched with both flower-drums. The brake mechanisms of the utility model are matched with two flower-drums, so two rear wheels can simultaneously carry out the brake; the overturn can not be generated caused by braking when the speed of the tricycle is high; the running of the tricycle is safe; the running speed can be enhanced; the speed can reach to 40 km/h.
Description
The utility model relates to the boosted tricycle that use in a kind of rural area.
Existing agricultural boosted tricycle mainly is made up of vehicle frame, wheel, railway carriage, actuating unit, stop mechanism, and its rear axle flexibly connects a trailing wheel, another trailing wheel of captive joint.The stop mechanism of this car is connected on the rear axle, owing to rear axle is only captiveed joint with a trailing wheel, so can only implement braking to a trailing wheel.Like this, when the speed of a motor vehicle is too fast, brake, roll-over accident will take place.So the speed of a motor vehicle of this car is slower, only be 24km/h.
The purpose of this utility model is to provide a kind of two brakings agricultural boosted tricycle, and brake roll-over accident can not take place when its speed of a motor vehicle was very fast, thereby improved the speed of a motor vehicle.
The purpose of this utility model is achieved in that this car comprises front-wheel, vehicle frame, Power train, assisted pedal stroke mechanism, railway carriage and two trailing wheels; Front-wheel connects vehicle frame, and vehicle frame connects Power train and assisted pedal stroke mechanism, and the vehicle frame rear end connects railway carriage and rear axle, and rear axle connects two Decorative drums, and two Decorative drums connect a trailing wheel respectively; The railway carriage bottom surface connects two leaf springs, and two leaf springs connect a spring block respectively, and spring block connects rear axle, and the end face of each spring block connects stop mechanism, and stop mechanism matches with each Decorative drum.
Described stop mechanism is that the brake treadle connects connecting rod, and connecting rod connects two fork arms, and two fork arms connect a double-block brake respectively.
Stop mechanism of the present utility model matches with two Decorative drums, can implement braking to two trailing wheels simultaneously, brakes when the speed of a motor vehicle is very fast and also can not overturn, and it is safer to drive a vehicle, thereby has improved road speed, car scooter 40km/h.
Elaborate below in conjunction with drawings and Examples.
Fig. 1 is the constructional drawing of an embodiment of the present utility model.
Fig. 2 is the connection diagram of trailing wheel, rear axle and stop mechanism among Fig. 1.
Fig. 3 is the double-block brake constructional drawing in the stop mechanism among Fig. 1 and Fig. 2.
Fig. 4 is the left view of Fig. 3.
1. front-wheels among the figure, 2. vehicle frame, 3. assisted pedal stroke mechanism, 4. Power train, 5. railway carriage, 6. connecting rod, 7. Decorative drum, 8. trailing wheel, 9. nut, 10. leaf spring, 11. spring blocks, 12. rear axles, 13. hinge wheels, 14. overriding clutchs, 15. double-block brakes, 16. fork arms, 17. brake shoes, 18. alignment pin, 19. reset tension springs, 20. braking pin shaft.
In Fig. 1, front-wheel (1) connects vehicle frame (2), and vehicle frame (2) connects Power train (4) and assisted pedal stroke mechanism (3), and vehicle frame (2) rear end connects railway carriage (5) and rear axle (12), and railway carriage (5) both sides, bottom surface connect a leaf spring (10) respectively.The brake treadle of stop mechanism connects connecting rod (6), and connecting rod (6) connects two fork arms (16).
In Fig. 2, each leaf spring (10) connects a spring block (11) respectively, and spring block (11) connects rear axle (12), and the end face of each spring block (11) connects a double-block brake (15) respectively.Double-block brake (15) one ends stretch into Decorative drum (7) inner chamber, and tolerance clearance is arranged between the two.Rear axle (12) connects two Decorative drums (7)), each Decorative drum (7) connects a trailing wheel (8) respectively.The Decorative drum on the left side (7) captive joint rear axle (12), the Decorative drum on the right (7) flexibly connects rear axle (12).Hinge wheel (13) connects foot-operated servomechanism (3), and overriding clutch (14) connects Power train (4).
In Fig. 3 and Fig. 4, the upper end of two brake shoes (17) of double-block brake (15) connects an alignment pin (18) respectively, the end face of alignment pin (18) connecting panel spring abutment (11).Brake shoe (17) lower end connects reset tension spring (19) and braking pin shaft (20), and braking pin shaft (20) connects fork arm (16), and fork arm (16) connects connecting rod (6).
When chaufeur tramps with one's feet down the brake treadle of stop mechanism, make the connecting rod (6) in the stop mechanism produce a F power, by fork arm (16) braking pin shaft (20) is produced clockwise and rotate.At this moment, the chamfered edge pin both sides of braking pin shaft (20) one ends produce the couple F1-F1 of a pair of opposite sign but equal magnitude, making two brake shoes (17) is centre of gyration with two alignment pin (18), enlarge to the arrow G direction and produce, make the asbestos car band on brake shoe (17) outside face prop up Decorative drum (7) inner chamber tightly, Decorative drum (7) is stopped operating, realize the purpose of trailing wheel (8) braking.
When the pin releasing of brake treadle of chaufeur, F power disappears, the F1-F1 couple also disappears simultaneously, reset tension spring (19) forces the chamfered edge pin of braking pin shaft (20) one ends to set back and puts, the cylindrical of two brake shoes (17) and Decorative drum (7) inner chamber produce the gap, Decorative drum (7) rotation that affranchises again.
