By adopting technique scheme, front-wheel bearing one end is located by limited step, the other end is spacing by bearing installation component installation component, installation ring is fixed on bearing seat, to the reset assembly of joining, slippage ring is given with installation ring the reset force that resets inside slippage hoop bearing mounting hole, because the reset force given is larger, when normal work, front-wheel bearing keeps installation position, when running into the situation of larger load, slippage ring can relatively the axial microdisplacement of bearing mounting hole to reach the possibility of the wearing and tearing avoiding front-wheel bearing and slippage ring, thus extend the service life of steering swivel, then avoid slippage ring too the to extrude deformation that front-wheel bearing causes front-wheel bearing of the confined planes of slippage slot, increase the service life further.
The utility model is set to further: described reset assembly comprises retracing spring, described installation ring is provided with the spring fitting block stretched in bearing mounting hole, described spring fitting block is annular element, described spring fitting block is inclined to set, the outer peripheral face of described spring fitting block reduces gradually along with the distance away from installation ring increases radius, and the outer peripheral face of described retracing spring and spring fitting block is put in supporting arranging.
By adopting technique scheme, the outer peripheral face of spring fitting block is inclined to set, and makes the installation of retracing spring more stable, and being subject to can retreating by trace in slippage slot and spring fitting block gap of large load, extends the service life of retracing spring.
The utility model is set to further: described slippage ring is provided with deformation ring towards front-wheel bearing, and described deformation ring is compressed between slippage ring and front-wheel bearing, and outer peripheral face and the slippage ring inner peripheral surface of described deformation ring are wedge-like engagement.
By adopting technique scheme, deformation ring is fitted according to front-wheel bearing true form, avoid the moment between the outer ring of front-wheel bearing and slippage ring two rigid members to rub and cause wearing and tearing, and deformation ring outer peripheral face and slippage ring inner peripheral surface to be the close-fitting of wedge-like engagement when it is subject to larger pressure on the contrary and between slippage ring better.
The utility model is set to further: described installation ring is circumferentially corresponding with between bearing seat is provided with mounting hole and hold-down bolt.
By adopting technique scheme, mounting hole and hold-down bolt form the detouchable mounting means of bearing seat and installation ring, are convenient to change and maintenance, and convenient disassembly, because both the mounting hole events circumferentially arranged all can be installed in any angle.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
