FRONT HEAD CONNECTING STRUCTURE FOR ROLLING STOCK
Document Type and Number:
Japanese Patent JP3398097
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simply and remarkably improve coupling strength of a car body underframe and a front head body structure by erecting a support member in a semi-circular arc shape in a front part of the car body underframe, erecting a pressing member at an inside edge of the front head body structure and fastening the front head body structure on the car body underframe with bolts in a state that the pressing member is made to be abutted on the support member.
SOLUTION: In front of a car body underframe 3, a support member 10 is welded and erected along the inside peripheral edge. A stay 11 is interposed between the support member 10 and a structural material of the vehicle underframe 3 and the support member 10 is reinforced. At a rear end edge of the front head body structure 16 of a front head (a driver's cab part), a pressing member 17 of a semi-circular arc shape which is the same as that of the support member 10 is welded and fixed, a stay 18 is interposed between the pressing member 17 and a structural material such as an end post 8 of the front head and the pressing member 17 is reinforced. In a state that the pressing member 17 is made to be abutted on the support member 10, the front head is fixed with the car body underframe 3 with connecting bolts. An abutting surface of the pressing member 17 and the support member 10 is sealed by a sealing material 19 and infiltration of rainwater into the front head is easily prevented.
