Abstract
A suspension system of a track flatcar comprises a push mechanism arranged under a cargo loading platform which is in rigid connection with the push mechanism. The push mechanism is arranged in a hydraulic cylinder which is arranged on one side of a supporting shaft. The supporting shaft is connected with a hub of the track flatcar. The suspension system of the track flatcar is simple and compact in structure, long in service life, and wide in utilization range. When the suspension system of the track flatcar is used, uprightly downward loads received by the track flatcar can be converted into pressure of liquid in the hydraulic cylinder to the wall of the cylinder so that a single uprightly downward load is enabled to be dispersed to other directions to reduce stress centralization, and therefore reduction of the biggest stress value of a weight-bearing part is favored, utilization of materials with relatively low strength is facilitated, dependence on the materials is reduced, and cost is lowered. Moreover, when used, the suspension system of the track flatcar can play a shock absorption function, and is favorable to improvements of smoothness and stability during transportation processes.
Description
Technical field
The utility model relates to a kind of suspension system, especially relates to a kind of rail flat car suspension system.
Background technology
Along with commercial production to improving constantly that the load-carrying of rail flat car requires, the load carrying ability of rail flat car constantly increases, the load-carrying level that can reach 300t that has.Therefore, this loading platform for rail flat car, suspension etc. are all had higher requirement.Traditional way is the ways such as thickening loading platform and the more high-intensity material of use, improves the load-carrying ability of heavily loaded rail flat car, but like this, tends to so that manufacturing cost rolls up, and is unfavorable for being widely used.Therefore, a kind of lighter, actv. vehicle body of design or suspension just become the active demand that improves heavily loaded rail flat car load-carrying level.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defects that prior art exists, and provides a kind of low cost of manufacture, rail flat car suspension system applied widely.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of rail flat car suspension system, comprise the thrust gear of being located at loading platform below, loading platform and thrust gear are rigidly connected, thrust gear places hydraulic actuating cylinder, hydraulic actuating cylinder is located at bolster one side, and bolster links to each other with the wheel hub of rail flat car.
Further, described thrust gear is more than two.
Further, described thrust gear is preferably piston.
During work, loading platform institute bearing load puts on the thrust gear, and it is descending to promote thrust gear, the hydraulic oil in the squeezed fluid cylinder pressure, so that the hydraulic actuating cylinder internal pressure rises, until when pressure equates with suffered load in the hydraulic actuating cylinder, the thrust gear stop motion.
The utility model is simple in structure, compact, long service life, and range of use is wide.Use the utility model, the suffered load straight down of rail flat car can be converted in the hydraulic actuating cylinder liquid to the pressure of casing wall, single straight down load is disperseed to other directions, having reduced stress concentrates, thereby be conducive to reduce the maximum stress value of load-supporting part, in order to use more low intensive material, reduce the dependence to material, reduce cost.Use the utility model, can also play the effect of damping, be conducive to strengthen the regularity and stability in the transportation.
Description of drawings
Fig. 1 is the utility model one embodiment front view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
With reference to Fig. 1, present embodiment comprises the thrust gear 2 of being located at loading platform 1 below, and loading platform 1 is rigidly connected with thrust gear 2, and thrust gear 2 places hydraulic actuating cylinder 3, and hydraulic actuating cylinder 3 is located at bolster 4 one sides, and bolster 4 links to each other with the wheel hub of rail flat car.
Described thrust gear 2 is piston.
Embodiment 2:
The difference of present embodiment and embodiment 1 is that described number of pistons is two, and two pistons all place hydraulic actuating cylinder 3.All the other are with embodiment 1.
Claims (3)
1. a rail flat car suspension system is characterized in that, comprises the thrust gear of being located at loading platform below, loading platform and thrust gear are rigidly connected, thrust gear places hydraulic actuating cylinder, and hydraulic actuating cylinder is located at bolster one side, and bolster links to each other with the wheel hub of rail flat car.
2. rail flat car suspension system according to claim 1 is characterized in that, described thrust gear is more than two.
3. rail flat car suspension system according to claim 1 and 2 is characterized in that, described thrust gear is piston.
