Abstract
The utility model discloses a three-wheel motorcar with a rear-mounted engine, comprising a vehicle bottom, an engine, a reverse gear and a differential speed device, wherein the vehicle bottom consists of a chassis and two half shafts; one ends of the half shafts are connected with two rear wheels respectively in a rotating way; the engine, the reverse gear and the differential speed device are assembled together to form an engine assembly with an integrated structure; and two output shafts of the differential speed device of the engine assembly are connected with the other ends of the two half shafts respectively in a driving way. The three-wheel motorcar has the obvious advantages of realizing the rear-mounted engine of the three-wheel motorcar, shortening the power transmission distance, simplifying the structure of the three-wheel motorcar, having good heat-dissipation effect, prolonging the service life of the engine, leading the engine to be away from the driver and the passengers, protecting the driver and passengers from being influenced and hurt by the heat, noise and vibration generated by the engine, well protecting the driver and the passengers when the engine fails to work, adopting the power output shaft of the engine to directly drive the rear wheels by the reverse gear and the differential speed device, and leading the assembling space not to be limited by the vehicle type and vehicle frame.
Description
Technical field
The utility model relates to motor-tricycle, especially relates to a kind of engine at extreme rear formula motor-tricycle.
Background technology
Existing motor-tricycle, driving engine all is mounted in the driver's seat below, the motor-tricycle weak point of this kind structure is mainly reflected in: 1, also needing could be with transmission of power to rear wheel through devices such as driving chain (or transmission shaft), diff, back axles, the power transmission approach is long, and watt loss is big, complex structure; 2, heat radiation is bad; 3, the independently back axle of reverse gear, band diff need be installed; 4, because engine behind front wheel is installed, make driver and crew be subjected to engine vibration, heating, influence of noise big, so can produce injury for a long time driver and crew.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, perfect heat-dissipating, chaufeur is not caused the engine at extreme rear formula motor-tricycle of Health cost.
For achieving the above object, the utility model can be taked following technical proposals:
Engine at extreme rear formula motor-tricycle described in the utility model, comprise at the bottom of the car that the semiaxis that is rotationally connected respectively by chassis, two ends and two rear wheels constitutes, driving engine, reverse gear and diff, it is overall that described driving engine, reverse gear and differential cluster are fitted together the driving engine that constitutes integrative-structure, and two output shafts of the described diff that this driving engine is overall drive with the other end of described two semiaxis respectively and are connected.
Described driving engine totally in, comprise that described power take-off shaft is meshed with the reverse gear power input gear by gear by the bent axle of air cylinder driven, by the magneto generator of crank-driven and the engine body that power take-off shaft constituted that is driven through change-gear set by bent axle; Described reverse gear power output gear is meshed with the diff reducing gear.
Rotor shaft end at described magneto generator is fixed with fan blade; On housing, offer vent window corresponding to the engine body of described fan blade.
The utility model advantage just is in existing horizontal 110 (1P52FMH series, on the basis of discharge capacity 100～150ml) driving engines, the become one driving engine of structure of described driving engine, reverse gear, diff and forced cooling fan blade is overall, drive by its diff and two semiaxis at the bottom of the car and to be connected, the rear portion of firm installation motor-tricycle, thereby the utility model possesses following obvious improvement:
1, the postposition that has realized driving engine is installed, and has both shortened the power transmission distance, has also played the effect of protection driving engine, makes the structure of motor tricycles motor bike, production technology simplify simultaneously, has well brought into play the performance of driving engine;
2, rear-mounted engine is compared with engine installation prior art below driver's seat, ventilate, and rapid heat dissipation, force-air cooling can make driving engine better be cooled off in addition, has prolonged the service life of driving engine;
3, engine at extreme rear is installed, and makes driving engine away from driver and crew, the influence and the injury of the heat of avoiding chaufeur to be subjected to driving engine producing, noise, vibrations, and when safety misadventure appears in driving engine, also can fine protection driver and crew;
4, the rearmounted driving engine of installing is overall, and direct drive trailing wheel, installing space are not limited by vehicle style and vehicle frame.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan structure scheme drawing of Fig. 1 driving engine overall installation position.
Fig. 3 is the overall structure for amplifying scheme drawing of Fig. 2 driving engine.
The specific embodiment
As shown in Figure 1 to Figure 3, engine at extreme rear formula motor-tricycle described in the utility model, comprise at the bottom of the car that the semiaxis 15 that is rotationally connected respectively by chassis 17, two ends and two rear wheels 14 constitutes, driving engine, reverse gear 6 and diff 9, it is overall 16 that described driving engine, reverse gear 6 and diff 9 fit together the driving engine that constitutes integrative-structure, and two output shafts of the described diff 9 of this driving engine overall 16 drive with the other end of described two semiaxis 15 respectively and are connected; Add the support on chassis 17, so the just firm rear portion that is installed in motor-tricycle of driving engine overall 16.In described driving engine overall 16, the engine body that magneto generator 3 that comprises the bent axle 2 that driven by cylinder 1, driven by bent axle 2 and the power take-off shaft 4 that is driven through change-gear set 5 by bent axle 2 are constituted, described power take-off shaft 4 is meshed with reverse gear 6 power input gears 7 by gear; Described reverse gear 6 power output gears 8 are meshed with diff 9 reducing gear 10.For realizing force-air cooling, be fixed with fan blade 12 in rotor shaft 11 ends of described magneto generator 3; On housing, offer vent window 13 corresponding to the engine body of described fan blade 12.
