Summary of the invention:
The purpose of this utility model is to provide a kind of road-sweeper propons drive transmission device, solve and both made road-sweeper sole rear portion have the space of placing dustbin and round brush cleaning part, satisfy low speed cleaning requirement again, and do not influence the technical problem of vehicle linear driving performance.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of road-sweeper propons drive transmission device comprises gearbox, differential mechanism and Cardan shaft, it is characterized in that: be provided with the front driving axle that two ends are connected with left and right two front-wheels respectively, it is indoor that this differential mechanism is positioned at the differential of front driving axle housing; Sole middle part is provided with gear reduction box, and the output shaft of this gear reduction box links to each other with differential mechanism on being arranged on sole middle part crossbeam with Cardan shaft, and its power shaft usefulness shaft coupling links to each other with gearbox.
Above-mentioned road-sweeper propons drive transmission device is characterized in that: this front driving axle is the steer drive front-axle with front-wheel steer machine.
Above-mentioned road-sweeper propons drive transmission device is characterized in that: the differential chamber of this front driving axle is symmetricly set on the position, center of housing, or is biased in a side at position, housing center.
Above-mentioned road-sweeper propons drive transmission device is characterized in that: this gearbox and motor are set in parallel on the crossbeam at sole middle part, are provided with the belt wheel transmission mechanism between the crankshaft output end of motor and the gearbox input shaft end.
Above-mentioned road-sweeper propons drive transmission device is characterized in that: gearbox links to each other with the crankshaft output end of the motor that is biased in the sole front portion with shaft coupling or Cardan shaft.
The utility model has the advantages that:
1. the gear by synchronous rotation drives the walking of two front-wheels, and the linearity of vehicle ' is good, has eliminated unnecessary load and the wearing and tearing of steering mechanism, has guaranteed driving stability again.
2. can utilize the steer drive front-axle of existing four-wheel drive vehicle, be convenient to make and reduce cost.
Motor can be before sole, the multi-faceted setting in middle part, can adapt to multiple model road-sweeper configured in one piece needs.
4. do not had the constraint of wheel transmission mechanism between two rear wheels, bigger space is provided, both helped the placement and the loading and unloading of rubbish bery case, helped yet the adjustment of round brush and its transmission mechanism and the operation of maintenance.
5. simplified the maintenance work of itself.
Description of drawings:
Fig. 1 is the schematic diagram of a kind of structure of the utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment:
See also illustrated in figures 1 and 2ly, the utility model comprises gearbox 8, differential mechanism and Cardan shaft 10.Gearbox 8 and motor 4 are arranged on sole 2 middle parts abreast, be provided with the belt wheel transmission mechanism of forming in driving pulley, passive belt wheel and V-belt 13 power of motor 4 is passed to gearbox 8, wherein driving pulley is fixed on motor 4 crankshaft output ends, passive belt wheel is fixed in the input shaft end of gearbox 8, and the V-belt then is embedded in the trough of belt of master, passive belt wheel.Belt wheel rotating mechanism 13 can single V-belt, also can be two V-belts, can also dispose the belt tension mechanism that is made of movable stand and contact roller.Be provided with gear reduction box 9 at sole 2 middle parts, be provided with shaft coupling 3 between the power shaft of this gear reduction box 9 and gearbox 8 output shafts, the rotating speed that gearbox 8 is transmitted further reduces, and cleans required pace through the last deceleration of differential mechanism to reach road-sweeper again.Between left and right two front-wheels 12, be provided with the front driving axle 11 that comprises housing and be supported on the left and right half in the housing, differential mechanism is arranged in the differential chamber 111 of front driving axle 11, one end of left and right half is connected with the left and right differential gear of differential mechanism respectively, their other end then is connected with left and right two front-wheels 12 respectively, then connect between the output shaft of the input shaft end of differential mechanism and gear reduction box 9 with Cardan shaft 10, synchronous with the angular velocity that guarantees the rotation of out of line differential mechanism power shaft and gear reduction box 9 output shafts.For making front-wheel 12 continue to have the function of turning to, can between the two ends of front driving axle 11 and front-wheel, be provided with and turn to driving mechanism, this just makes front driving axle 11 identical with the steer drive front-axle structure that existing four-wheel drive vehicle uses, and can be convenient to greatly make, and reduces cost.
