Problems solved by technology

Due to the large load under loading conditions, the connecting bolts 3 are subjected to a large shear force during the starting or braking process of the vehicle, and the phenomenon of bolt loosening often occurs or accidents in which the bolts are sheared in severe cases, resulting in the axle housing and the body. The phenomenon that the rack is detached, causing a vehicle accident

Abstract

The invention relates to a connection structure of a vehicle body and a vehicle axle. The connection structure comprises block-shaped pedestals which are located on a vehicle axle shell body on the inner side of a vehicle wheel; connection support base plates are distributed on a vehicle body rack and are integrally welded to the lower edges of two-rib plates of which the surfaces are arranged vertically, the surfaces of the connection support base plates are arranged horizontally and attached to the upper surfaces of the block-shaped pedestals, the connection support base plates and the block-shaped pedestals are connected through connection bolts, and the connection bolts are arranged vertically; the vehicle axle shell body is provided with auxiliary rib plates extending in the front and back directions of the vehicle body rack, and the suspension ends of the auxiliary rib plates are connected with the vehicle body rack; inertia force generated by the tendency of separating of the vehicle axle shell body from the vehicle body rack caused by inertia acts on the connection bolts in a tiny shear force mode, and while, the most of the inertia force is born by the auxiliary rib plates; and thus, the reliability of connection of the vehicle axle shell body and the vehicle body rack can be ensured, the normal working condition of a vehicle is guaranteed, the maintenance cost is reduced, and the maintenance time is shortened.

Description

technical field [0001] The invention relates to a connection structure between a vehicle body and an axle. Background technique [0002] Underground scrapers are mainly used in mines, mainly for shoveling and transporting minerals. The working conditions are extremely harsh and the workload is heavy. Wheels are connected to both ends of the axle. The axle housing inside the wheel is connected to the body or body machine. The specific connection structure includes a block-shaped pedestal 1, the block-shaped pedestal 1 is located on the axle housing inside the wheel, and a connecting support 2 is arranged on the body frame. The two ribs 2B, the lower edge of the ribs 2B are connected to the connecting plate 2A, the lower surface of the connecting plate 2A is attached to the upper surface of the block pedestal 1 and there is a connecting bolt 3 between them, and the connecting bolt 3 is vertical layout. The vehicle body G at the position where the connecting support 2 is loca...
