Abstract
A damper support is provided which is especially for supporting shock absorbers in motor vehicles. The damper support is built in on the vehicle body between two clamping surfaces in axial direction of a piston rod of a shock absorber and is connected through a central opening to the piston rod of the shock absorber. At least one outer axial end face has at least one rise and one low in peripheral direction and the rises and lows of the outer axial end faces generate a waveform in the peripheral direction.
Claims25
A damper support for supporting a shock absorber in a motor vehicle having a vehicle body, the shock absorber defining a longitudinal axis and including a piston rod and two holding members defining respective clamping surfaces, the damper support being mounted on said vehicle body along said longitudinal axis between said clamping surfaces and the damper support comprising:
- a body defining a central opening for accommodating said piston rod;
- means for connecting said piston rod to said body;
- said body having at least one outer axial end face for coacting with one of said clamping surfaces;
- said end face having a plurality of lows and highs formed thereon in a peripheral direction about said opening;
- and, said highs and lows alternating one with the other to define a waveform in said peripheral direction.
A shock absorber and air spring assembly for a motor vehicle having a chassis and a wheel suspension and said assembly being mountable between said chassis and said wheel suspension, the assembly comprising:
- an air spring including:
- a cover unit attached to said chassis;
- a roll-off piston;
- and, a flexible member having a lower end portion attached to said roll-off piston to form a rolling lobe and an upper end portion attached air tight to said cover;
- said flexible member enclosing a volume of air and deflecting over a spring path during operation of said assembly;
- a shock absorber interposed between said cover and said wheel suspension;
- said shock absorber including a cylinder and a piston disposed in said cylinder and having a piston rod;
- said roll-off piston being arranged on said cylinder;
- a damper support connecting said piston rod to said cover unit;
- said cover unit defining two clamping surfaces for clamping said damper support in the axial direction of said piston rod;
- a guide ring fixedly connected to said cover unit;
- an ancillary spring arranged concentrically to said piston rod and guided in said guide ring;
- said cylinder having a first end facing away from said damper support and said end being connected to said wheel suspension;
- said cylinder having a second end supported against said ancillary spring when said assembly deflects in compression during operation thereof;
- and,
- said damper support including:
- a body defining a central opening for accommodating said piston rod;
- means for connecting said piston rod to said body;
- said body having at least one outer axial end face for coacting with one of said clamping surfaces;
- said end face having a plurality of lows and highs formed thereon in a peripheral direction about said opening;
- and,
- said highs and lows alternating one with the other to define a waveform in said peripheral direction.
