Title: Impact absorbing mounting for lorry load - has friction collar plastically deformed by coupling shaft being pulled through it
Inventor: YAMANAKA AKIRA
IPC: B60R21/00
Filed: 1976-04-13
Abstract: The load support frame (4) of the lorry is coupled to the chassis (2) by an impact absorbing coupling in which a profiled shaft (10) is pulled through a collar (9) and deforms it to absorb the impact force. The shaft is mounted between two sets of angle pieces (6, 8) which are bolted to fixed angle pieces (5, 7) bolted to the chassis and load support. The separate bolts to the angle pieces provide a universal joint to the coupling. The joint is secured by a set of shear pins (63, 52, 82, 72) which gives it rigidity for normal use. In a collision the shear pins break to allow the best possible action for the coupling. The coupling is set between the load and the chassis and can also be used to support the cab.
