Background
At present, the shape-walking part of a vehicle in the field of rail transit is usually realized by using a form of a bogie, and the transmission of longitudinal force between the bogie and a vehicle body is mainly realized by using a central traction device or a mode of using a swing bolster and a traction pull rod and the like.
The conventional traction pull rod structure is that circular holes are formed in two ends of a steel torsion bar, and rubber nodes are installed in the circular holes to realize elastic connection of a vehicle body and the bogie.
In the face of vehicles of different types and different axle weights, the rubber node type traction pull rod always needs to be matched with the performance of the whole vehicle by redesigning the rigidity of the rubber node, so that when the rubber node type traction pull rod is applied to different vehicles, the traction pull rod device needs to be frequently redesigned.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing modular design pull rod type draw gear to the problem that exists, mainly be applied to suspension type monorail vehicle bogie, but not limited to use in suspension type monorail vehicle bogie, can realize obtaining big torsion angle in vertical and horizontal homoenergetic, and through the modular design, through the quantity of simple adjustment metal rubber spring, can realize the change of longitudinal stiffness, both can adjust to the longitudinal big rigidity, can adjust to the longitudinal little rigidity again, need not frequent redesign rubber rigidity both can satisfy the various gross rail load on axle's of various systems vehicle design demand, and can obtain good performance.
The utility model discloses a technical scheme be like:
modular design pull rod formula draw gear, including the pull rod, still include two tip threaded rods and a plurality of rubber spring, the pull rod both ends respectively with the connecting end threaded connection and the locking of tip threaded rod, rubber spring is in proper order from the free end of tip threaded rod to the connection end direction cluster and spacing through spacing retaining ring on the pole, then carries out spacing locking to two pairs of rubber spring with gland, gasket and hexagon nut at the free end of tip threaded rod.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. by adopting the idea of modular design, the change of longitudinal stiffness can be realized by simply adjusting the number of the metal rubber springs, the longitudinal stiffness can be adjusted to be large longitudinal stiffness, the longitudinal small stiffness can be adjusted, the rubber springs do not need to be frequently redesigned, the design requirements of various types of axle weight vehicles can be met, the whole vehicle has good performance, the design process is greatly simplified, and meanwhile, the large torsion angles in the vertical direction and the transverse direction are realized so as to adapt to more working conditions;
2. the end threaded rods connected with the two ends of the pull rod in a threaded mode are designed at the two ends of the pull rod, hexagonal nuts are used for locking, the pull rod is adjustable in length direction, the installation scheme can adapt to spaces with different sizes within a fixed range, and more working conditions are adapted.
Preferably, the two ends of the pull rod are provided with internal thread sections, the connecting section of the end threaded rod is provided with an external thread section, the external thread section of the end threaded rod is screwed into the internal thread section of the pull rod and is locked through the hexagon nut , and the pull rod type traction device can be adjusted in the length direction by loosening the hexagon nut and then rotating the end threaded rod.
Preferably, before the rubber spring is threaded on the end threaded rod, the sleeve is sleeved to isolate the rubber from the end threaded rod, so that the rubber is ensured to be free of abrasion.
The rubber spring is preferably formed into a three-layer structure by middle rubber and two metal plates bonded to two sides through a vulcanization process, wherein the metal plates can effectively prevent the rubber spring from being displaced too much laterally and even falling off due to rubber aging, the inner diameter of the rubber spring is far larger than the outer diameter of the end threaded rod, the shaft sleeve and the two metal plates are in small clearance fit to ensure the accuracy of lateral positioning between the rubber spring and the end threaded rod, and the shaft sleeve can be conveniently replaced after being worn without replacing the end threaded rod, the metal plates and the two metal plates are respectively formed into convex and concave matched structures on the plates so as to facilitate installation and positioning between adjacent rubber springs, so that the rubber springs can be more conveniently assembled, and the rubber springs can be more conveniently and accurately positioned in the axial direction and the radial direction, and when the two ends of the traction pull rod are twisted, the lateral movement cannot occur.
