Abstract The invention provides a road vehicle having two vehicular sections connected together by an articulation joint having on each side thereof a shock-absorbing or arrester device having a pair of arms adapted to engage each other through an abutment when the two vehicular sections pivot relative to each other in one direction and to become disengaged from each other when the two vehicular sections pivot relative to each other in the other direction. The abutment of each pair of mutually engaging arms has an interlocking profile to prevent lateral movement therebetween, and stop mechanisms are provided to retain each arm when they are disengaged from each other, in such a position that when they next become engaged owing to said vehicular sections pivoting in said one direction, said arms are positioned for interlocking engagement with each other.
A road vehicle comprising: a front vehicular section; a rear vehicular section; an articulation joint pivotally interconnecting said front and rear sections; an arrester device on each side of said articulation joint having a pair of arms, said arms connected respectively to said front and rear sections, abutment means provided on said arms, said arms being adapted to engage each other through said abutment means when said vehicular sections pivot relative to each other in one direction and to become disengaged from each other when said two vehicular sections pivot relative to each other in the other direction, said abutment means of each pair of mutually engaging arms having an interlocking profile to prevent lateral movement therebetween; and stop means provided for retaining each arm, when they are disengaged from each other, in such a position that when they next become engaged, owing to said vehicular sections pivoting in said one direction, said arms are positioned for interlocking engagement with each other.

A road vehicle comprising: a front vehicular section; a rear vehicular section; an articulation joint pivotally interconnecting said front and rear sections; an arrester device on each side of said articulation joint having a pair of arms, said arms connected respectively to said front and rear sections, abutment means provided on said arms, said arms being adapted to engage each other through said abutment means when said vehicular sections pivot relative to each other in one direction and to become disengaged from each other when said two vehicular sections pivot relative to each other in the other direction, said abutment means of each pair of mutually engaging arms having an interlocking profile to prevent lateral movement therebetween; and stop means provided for retaining each arm, when they are disengaged from each other, in such a position that when they next become engaged, owing to said vehicular sections pivoting in said one direction, said arms are positioned for interlocking engagement with each other.
Claim 3
Dependent Claim
29 words
A road vehicle as claimed in claim 1, in which the interlocking profile of the abutment means of each pair of arms is formed by interlocking elevations and depressions.
Claim 4
Dependent Claim
30 words
A road vehicle as claimed in claim 1 in which each abutment means is disposed convexly about an axis parallel to the axis of articulation and is of denticulated form.
