Problems solved by technology

[0003] The axial rubber pad includes iron parts and a rubber layer. In order to ensure the stiffness of the axial rubber pad, in the prior art, the stiffness of the interlayer is increased by increasing the hardness of the interlayer. However, under this setting, the hardness of the rubber layer is relatively high and the resilience Smaller, prone to permanent deformation during work, resulting in unusability and affecting its service life

Abstract

The invention relates to an axial rubber pad and a cross supporting bogie. The axial rubber pad comprises an iron part, a top plate, a rubber layer and a reinforcing part; the iron part is of a cylindrical structure; the rubber layer comprises a columnar part, the columnar part is arranged outside the iron part in a sleeving manner, a gap is reserved between the columnar part and the iron part, the lower portion of the columnar part extends outwards in the radial direction to form a boss part, and the inner wall of the lower portion of the boss part is fixed to the outer wall of the iron part;the reinforcing part is embedded in the boss part in the circumferential direction; and the top plate comprises an axial part and an extending part, the axial part is fixed to the outer wall of the columnar part, and the extending part is fixed to the top end face of the boss part. By means of the axial rubber pad, the service life of the axial rubber pad can be effectively prolonged, so that themaintenance and application cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of elastic components, in particular to an axial rubber pad and a cross support bogie. Background technique [0002] The axial rubber pad is the core component of the cross braced bogie. The application of the axial rubber pad realizes the elastic connection between the cross bar and the side frame support seat, and ensures the anti-diamond stiffness and long-term operation stability of the bogie. In order to further reduce maintenance and operation costs, and solve the mismatch between the life cycle of truck rubber products and the existing factory repair cycle, it is necessary to ensure the service life of the axial rubber pad. [0003] The axial rubber pad includes iron parts and rubber layer. In order to ensure the stiffness of the axial rubber pad, in the prior art, the stiffness of the interlayer is increased by increasing the hardness of the interlayer. However, under this setting, the hardness of th...
