Abstract

A coupling structure for vehicle chassis members couples a ball joint member and an axle housing used for a vehicle to each other. The structure includes a socket that has a substantially columnar external shape, is provided in the ball joint member, and has a socket bolt groove throughout a circumference in an outer circumferential surface of the socket. The structure also includes a collar that has a substantially cylindrical shape and is disposed so as to surround an outer circumferential surface of the socket. The axle housing has a coupling hole having a substantially columnar internal shape into which the socket is inserted. The ball joint member and the axle housing are coupled to each other by disposing the socket in the coupling hole while the socket is surrounded by the collar.

Dependent claims

A coupling structure for vehicle chassis members that couples a first chassis member and a second chassis member used for a vehicle to each other, the structure comprising:

a coupling part that has a substantially columnar external shape, that is provided in the first chassis member, and that has a bolt groove throughout a circumference in an outer circumferential surface of the coupling part having the substantially columnar external shape;
and
a collar that is formed separately from the first chassis member and the second chassis member, that has a substantially cylindrical shape, and that is disposed so as to surround an outer circumferential surface of the coupling part having the substantially columnar external shape,
wherein the second chassis member has a coupling hole having a substantially columnar internal shape into which the coupling part is inserted, and
wherein the first chassis member and the second chassis member are coupled to each other by disposing the coupling part in the coupling hole having the substantially columnar internal shape while the coupling part is surrounded by the substantially cylindrical collar.
