Parking devices for vehicles

摘要

A parking device for a motor vehicle comprises a pair of parking rollers 10, 11 rotatably mounted in respective roller mounting members 22, 23 which are connected to respective ends of an extensible power means 12 (e.g. a hydraulic ram) and which are arranged to be transported along respective rails 24, 25 on extension or retraction of the power means, each rail extending from a mounting on the sprung part of the vehicle under the floor of the vehicle downwardly and outwardly to a location adjacent to a respective one of a pair of road wheels of the vehicle, so that extension of the power means causes the assembly of parking rollers, roller mounting members and power means to move bodily from a retracted position clear of the road and adjacent to the upper ends of the rails to an operative position adjacent to the said pair of road wheels, in which operative position the parking rollers take the weight of the adjacent end of the vehicle and enable it to be moved sideways. Preferably the weight of the end of the vehicle is taken through jacking abutments 35 on the upsprung part of the vehicle co-acting with the roller mounting members through pivotally mounted jack-links 31, 32 which swing down on final extension of the power means. The rails may be of round- section rod or wire, but are preferably hollow with a longitudinal slot so as to accommodate a runner attached to the respective roller mounting member. IMAGE
