Abstract
The utility model discloses a semitrailer pulls an additional strengthening. It includes the support and installs the saddle body on the support through round pin axle, the cover has elastic material to make between the periphery of round pin axle and the support a seat cover, and fixed the being provided with boss that lies in support top on the inboard bottom surface of the saddle body, the bottom surface of boss has the arcwall face that suits with the support top, contacts between the top surface of support and the arcwall face of boss or has a clearance. After adopting foretell structure, when saddle body bearing load, a seat cover can cushion absorbs partly energy, and when a seat cover was out of shape to support top and the compelled contact of saddle body boss, a seat cover is the atress no longer, although a feasible seat cover hardness is low not fragile from this, simultaneously, saddle body vertical force has reduced a round pin shearing force of bearing on directly transmitting the support, has improved the stress of saddle body support junction, has improved the life who draws the seat.
Description
Technical field
The utility model relates to a kind of mounting structure of superimposed trailer appurtenances, and specifically a kind of traction base of semitrailer strengthens structure.
Background technology
As everyone knows, the traction seat of superimposed trailer comprises a saddle body and one for supporting the bearing of saddle body, saddle body is arranged on bearing by the bearing pin of bearing, simultaneously in order to reduce the wearing and tearing of pivot pin, the cover for seat that flexible material is made is overlapped in usual meeting between bearing pin periphery and bearing, traditional this mounting structure, because its structure design is unreasonable, on the one hand, the shearing force that bearing pin is subject to is larger, bearing pin is easily damaged, in addition on the one hand, the cover for seat force rate that is squeezed is larger, a cover for seat is made to be very easy to wearing and tearing, thus reduce the service life of traction seat.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of shearing force that can reduce bearing pin and bear, and improves the strained condition of saddle body hinge-point, improves the traction base of semitrailer reinforcement structure in traction seat service life.
In order to solve the problems of the technologies described above, traction base of semitrailer of the present utility model strengthens structure, comprise bearing and be arranged on the saddle body on bearing by bearing pin, the cover for seat that flexible material is made is overlapped between the periphery of bearing pin and bearing, the inside bottom surface of saddle body is fixedly installed the boss be positioned at above holder top, the bottom surface of boss has the arcwall face adapted with holder top, the Contact of the end face of bearing and the arcwall face of boss or have gap.
The inside bottom surface of described saddle body is fixedly installed the two pieces of baffle plates being positioned at a cover for seat both sides, two pieces of described baffle plates are provided with mounting hole, and described bearing pin is serially connected in the mounting hole of baffle plate.
The side of described bearing pin is provided with bearing pin pad.
Described bearing settlement has two, and the inside bottom surface of saddle body is fixedly installed two pieces of bosses, every block boss lays respectively at the top of a holder top.
After adopting above-mentioned structure, due to overlap a cover for seat that flexible material makes and saddle body between the periphery of bearing pin and bearing inside bottom surface on be fixedly installed the boss be positioned at above holder top, when saddle body bearing load, cover for seat can snubber part energy, when cover for seat be deformed into holder top be forced to contact with saddle body boss time, prop up cover for seat no longer stressed, although make a cover for seat hardness low but not fragile thus, simultaneously, saddle body vertical power is directly delivered on bearing, reduce the shearing force that bearing pin bears, improve the strained condition of saddle body bearing junction, improve the service life of traction seat.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view that the utility model traction base of semitrailer strengthens structure;
Fig. 2 is the A-A place cross section structure schematic diagram of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, structure is strengthened to traction base of semitrailer of the present utility model and is described in further detail.
As shown in the figure, traction base of semitrailer of the present utility model strengthens structure, comprise the bearing 1 that top has mounting hole and the saddle body 3 be arranged on bearing 1, wherein, saddle body 3 is serially connected in bearing mounting hole by a bearing pin 2 and installs, the cover for seat 4 that flexible material is made is overlapped between the periphery of bearing pin 2 and the inside face of bearing 1 mounting hole, said cover for seat is preferably rubber coating, the inside bottom surface of saddle body 3 is fixedly installed the boss 5 being positioned at bearing 1 over top, the bottom surface of boss 5 has the arcwall face 6 adapted with bearing 1 top, contact between the end face of bearing 1 and the arcwall face 6 of boss 5 or there is gap.
Further, the inside bottom surface of said saddle body 3 is fixedly installed the two pieces of baffle plates 7 being positioned at cover for seat 4 both sides, two pieces of baffle plates 7 are provided with mounting hole, installed by nut after in the mounting hole that bearing pin 2 is serially connected in baffle plate 7, bearing pin pad 8 is installed between nut and the baffle plate corresponding to it 7, makes saddle body 3 be installed by two pieces of baffle plates 7 thus.
Again further, said bearing 1 is provided with two, the inside bottom surface of saddle body 3 is fixedly installed two pieces of bosses 5, every block boss 5 lays respectively at the top at bearing 1 top, saddle body 3 is serially connected in respectively in each bearing mounting hole by two bearing pins 2 and installs, rubber sleeve is overlapped respectively between the periphery of every root bearing pin 2 and the inside face of each bearing 1 mounting hole, the bottom surface of every block boss 5 all has the arcwall face 6 adapted with each bearing 1 top, contacts respectively or have gap between the end face of each bearing 1 and the arcwall face 6 of every block boss 5.
Adopt such structure, each increase by one piece of boss above two bearings of left and right, this structure is when saddle body bearing load, in each bearing, rubber coating all can snubber part energy, when rubber coating be deformed into holder top be forced to contact with saddle body boss time, rubber coating is no longer stressed, although so rubber coating hardness is low but not fragile, saddle body vertical power is directly delivered on bearing, reduce the shearing force that pins is born, improve the strained condition of saddle body bearing junction, its result of use is better.
