Description
Technical field
The utility model relates to a kind of rail vehicle running gear.
Background technology
The logistics dolly that adopts in the existing logistics system is to walk at double track, and the track consumptive material is many, the cost height, and floor area is big.Simultaneously the roller of logistics dolly is when double track is walked, and the side does not have constraint, as when being subjected to side force, is easy to rollover.
Summary of the invention
The purpose of this utility model is in order to solve the defective that prior art exists, the rail vehicle running gear that a kind of cost is low, be difficult for rollover to be provided.
In order to achieve the above object, the utility model provides a kind of rail vehicle running gear, comprises guide rail and actuating device; Described guide rail is the bilateral rectangular guideway; The actuating device of telling comprises upper roller, bottom roller, rolling wheel support and gear drive; Described upper roller and bottom roller are located at respectively on the rolling wheel support, and the upper end of upper roller contacts with the upper side of guide rail, and the lower end of bottom roller contacts with the downside of guide rail; Described gear drive places in the rolling wheel support, and the output shaft of gear drive is connected with bottom roller with upper roller respectively.
Further improvement of the utility model is: the said gear transmission device comprises the driving gear that is connected on the input shaft, be connected to last driven gear and following driven gear, the transition axis on the described output shaft and be connected transition gear on the transition axis; The described driven gear of going up meshes with driving gear and following driven gear respectively; Described transition gear respectively with adjacent two on driven gear or the engagement of adjacent twice driven gears; Described pto input shaft is bearing on the rolling wheel support.
Wherein, upper roller and bottom roller are respectively three pairs, and the every pair of upper roller and bottom roller are symmetrically set in the both sides of rolling wheel support respectively, and place in the guide rail of respective side.Bottom roller be located at upper roller under; The upper end of described upper roller to the distance of the lower end of bottom roller greater than the rectangular guideway distance between the side up and down.
Above-mentioned rail vehicle running gear also comprises the chassis; Rolling wheel support top is located on described chassis, and by guide rail support on upper roller and bottom roller.
The utility model has the following advantages compared to existing technology: the utility model rail vehicle running gear adopts single bilateral rectangular guideway to replace two guide rails, reduces consumptive material, and cost-cutting has also reduced floor area simultaneously.Roller design about the utility model adopts by contacting in the crack continuously the side up and down with guide rail, makes the rail vehicle running gear be difficult for because the gap causes pitching when operation, has guaranteed the steady of operation, and has not influenced the rotation of roller.Cooperate the design of bilateral rectangular guideway simultaneously, utilize the left and right side of rectangular guideway to retrain last bottom roller two ends, make bottom roller be difficult for guaranteeing the smooth running of rail vehicle running gear because the double swerve getaway causes rollover.

The specific embodiment
Below in conjunction with accompanying drawing the utility model rail vehicle running gear is elaborated.
Referring to Fig. 1, Fig. 2, the utility model rail vehicle running gear comprises guide rail 1, chassis 4 and actuating device 2.Actuating device 2 comprises upper roller 21, bottom roller 22, rolling wheel support 23 and gear drive 3.Guide rail 1 is the bilateral rectangular guideway.Upper roller 21 and bottom roller 22 are equipped with three pairs, bottom roller 22 be located at upper roller 21 under, the every pair of upper roller and bottom roller are symmetrically set in the both sides of rolling wheel support 23 respectively.The upper end of upper roller 21 contacts with the upper side 11 of guide rail 1, and the lower end of bottom roller 22 contacts with the downside 12 of guide rail 1.The upper end of upper roller 21 is slightly larger than rectangular guideway distance between the side about in the of 1 to the distance of the lower end of bottom roller 22, make that touch mutually in no gap between upper and lower roller and the guide rail 1 upper and lower side, but do not influence the normal rotation of bottom roller, guaranteed that the rail vehicle running gear is difficult for pitching when operation; And the left and right side of guide rail 1 has retrained upper and lower roller two ends, bottom roller is difficult for because the double swerve getaway causes rollover, thereby guarantees the smooth running of rail vehicle running gear.Gear transmission machine 3 places in the rolling wheel support 23.Rolling wheel support 23 tops are located on chassis 4, and are bearing on upper roller 21 and the bottom roller 22 by guide rail 1.Rail vehicle can directly be located on the chassis 4, makes things convenient for the carrying of goods in the logistics progress.
Referring to Fig. 3 to Fig. 6, gear drive 3 comprises input shaft 31, be connected driving gear 32 on the input shaft 31, go up output shaft 33, be connected last driven gear 34, time output shaft 35 on the output shaft 33, be connected down following driven gear 36, the transition axis 37 on the output shaft 35 and be connected transition gear 38 on the transition axis 37.Last driven gear 34 respectively with driving gear 32 and 36 engagements of following driven gear, transition gear 38 respectively with adjacent two on driven gear 34 or adjacent twice driven gears 36 mesh.Input shaft 31, last output shaft 33 and following output shaft 35 are bearing on the rolling wheel support 23.Input shaft 31 stretches out guide rail 1, external motor.Last output shaft 33 two ends connect a pair of upper roller 21 respectively, and defeated 35 two ends connect a pair of bottom roller 22 respectively down.
