Abstract
The invention relates to a primary suspension constant contact resilient stop catch for an underground vehicle, comprising a wedge-shaped fixing seat. The top end of the fixing seat is sleeved with a first inclined wedge-shaped rubber layer, the outer side of the first rubber layer is sleeved with a jacket, and the fixing seat, the jacket and the first rubber layer are vulcanized into a whole; the top end of the jacket is provided with outside screw threads which are connected with the inside screw threads of a cover plate, and the jacket and the cover plate are connected and fixed by an elastic pin; a second rubber layer is arranged on the cover plate, a nylon plate is arranged on the second rubber layer, and the cover plate, the second rubber layer and the nylon plate are vulcanized into a whole; a clearance is formed between the cover plate and the fixing seat, and the lateral extended line of the first rubber layer forms an inclined angle with the horizontal plane of the bottom of the cover plate; the middle of the fixing seat is provided with a through hole from top to bottom for holding a hanging piece, and the side surface of the fixing seat is provided with a through ventilation hole from inside to outside. The invention has simple and reliable structure, adjustable parameters, function of rigid stop and no abrasion, fasteners or maintenance.
Description
Technical field
The present invention relates to a kind of elastic bolster guide, relating in particular to a kind of metro vehicle bogie is constant contact resilient backstop with one.
Background technology
Because the railcar load change, one is that suspension gear generally is equipped with constant contact resilient backstop, to reach the purpose of sprung partses such as protection spring.The elastic bolster guide form that generally adopts is the rubber metal pad structure at present, and the shortcoming of this structure is that its stiffness parameters only depends on the adjustment rubber hardness to realize, but the hardness setting range of rubber is limited, so design is limited to.Another shortcoming is that the rigidity linearity of rubber pad is relatively poor, and stiffness variation is bigger in whole whole of life, and owing to do not establish rigidity backstop, makes the backstop stress excessive and premature failure causes the damage of sprung partses such as spring easily.Based on the shortcoming of above-mentioned elastic bolster guide, be necessary to design a kind of simple and reliable for structure, parameter is adjustable, elastic bolster guide with rigidity backstop function.
Summary of the invention
Technical matters to be solved by this invention is at the prior art deficiency, provide a kind of simple and reliable for structure, parameter is adjustable, primary suspension constant contact resilient stop catch for underground vehicle with rigidity backstop function.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of primary suspension constant contact resilient stop catch for underground vehicle, it comprises the permanent seat of wedge type, first rubber layer of the sheathed wedge type in the top of this permanent seat, the sheathed overcoat in the outside of first rubber layer, and permanent seat, overcoat and first rubber layer are sulfided into an integral body; The top of described overcoat is provided with outside thread, the female connection of this outside thread and a cover plate, and connect described overcoat and described cover plate fixing with a resilient pin; Top laying second rubber layer of cover plate, the top tiling of second rubber layer is provided with nylon sheet, and cover plate, second rubber layer and nylon sheet are sulfided into an integral body; The end face of described first rubber layer forms the space that the cross section is a back taper, makes to form a gap between described cover plate and the permanent seat, makes between the side extended line of described first rubber layer and the described cover plate bottom water plane shape in an angle simultaneously; The hole that is used for ccontaining sprung parts and up/down perforation is offered in the centre of this permanent seat, and the inside and outside air extractor vent that connects is offered in the side of this permanent seat.
Compared with prior art, the beneficial effect that the present invention had is: form a gap between cover plate of the present invention and the permanent seat, by the stroke between this gap may command elastic bolster guide and the rigidity backstop, simultaneously between the side extended line of first rubber layer and the cover plate bottom water plane shape in an angle, this angle angle can be adjusted according to the load and the rigidity requirement of product.The inside and outside air extractor vent that connects is also offered in the side of permanent seat, the balance of inner and outer air pressure during with the work of assurance elastic bolster guide.The present invention is provided with the macromolecule nylon plate at the top, second rubber layer is set between nylon sheet and cover plate, between overcoat and permanent seat top, first rubber layer is set, these are provided with the impact in the time of can reducing elastic bolster guide work, satisfy the requirement of subway Vehicle damper noise reduction, thereby make integral structure of the present invention not have abrasion, fastener-free, can be implemented in non-maintaining use in the whole whole of life, satisfy the needs of subway vehicle suspension system variable load well.
Description of drawings
Fig. 1 is the structural representation of primary suspension constant contact resilient stop catch for underground vehicle of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes the permanent seat 1 of a wedge type, the sheathed overcoat 3 in the outside of first rubber layer, 10, the first rubber layers 10 of the sheathed wedge type in the upper end of this permanent seat 1, and permanent seat 1, overcoat 3 and first rubber layer 10 are sulfided into an integral body.The top of this overcoat 3 is provided with outside thread, the female connection of this outside thread and cover plate 5, and connect overcoat 3 and cover plate 5 fixing with a resilient pin 4.After cover plate 5 top also laid second rubber layer 9, tiling was provided with nylon sheet 7 on second rubber layer 9 again, and cover plate 5, second rubber layer 9 and nylon sheet 7 are sulfided into an integral body.The end face of first rubber layer 10 forms the space that a cross section is a back taper, forms a gap 8 between cover plate 5 and the permanent seat 1 thereby make, and this gap is used to control the stroke between elastic bolster guide and the rigidity backstop, can adjust according to different designing requirements; Also make simultaneously between the side extended line of first rubber layer 10 and the cover plate 5 bottom water planes shape in an angle 6, this angle angle can be adjusted according to the load and the rigidity requirement of product.The hole 11 that is used for ccontaining sprung parts and up/down perforation is offered in the centre of permanent seat 1, and mounting hole 12 is offered in the bottom of permanent seat.The inside and outside air extractor vent 2 that connects is also offered in the side of permanent seat 1, the balance of inner and outer air pressure during with the work of assurance elastic bolster guide.
The present invention is provided with macromolecule nylon plate 7 at the top, second rubber layer 9 is set between nylon sheet 7 and cover plate 5, between overcoat 3 and permanent seat 1 top first rubber layer 10 is set, these are provided with the impact in the time of can reducing elastic bolster guide work, satisfy the requirement of subway Vehicle damper noise reduction.
