    摘要: Disclosed is a support unit for the cab of a utilitarian vehicle having a separate cab and chassis. The support unit includes a hydraulic piston and cylinder, including a compression spring, connected between the cab and the chassis. Fixed to the hydraulic support cylinder unit is a directional control valve which selectively directs and drains pressurized hydraulic fluid to or from the hydraulic support cylinder unit. The directional control valve is journalled to a lever pivoted to the cab. Also journalled to the lever are an elastically centered rod and an absorber element having an inelastically adjustable length. Dynamic fluctuations of the distance between the chassis and cab are opposed by the hydraulic support cylinder unit as actuated by the directional control valve. Static fluctuations in the distance between the chassis and the cab are accommodated by the hydraulic support cylinder unit together with the absorber element.
