Problems solved by technology

Although this type of suspension provides a high lift path, it cannot be applied to vehicles with low ride heights
In addition, the lateral pushrods create unfavorable drive performance and the overall weight of the suspension components is relatively high

Embodiment Construction

[0028] figure 1 Two pneumatic axle suspensions of the present invention are shown placed in the substructure of a vehicle such as a heavy goods vehicle. The driving direction of the car is indicated by the arrow F, which is collectively referred to as "the front" hereinafter, and the reverse direction toward the rear of the car is collectively referred to as the "rear". The pneumatic axle suspension 10 is installed in the substructure of the vehicle frame, which is not shown in full for the sake of clarity. The left and right parts of the axle suspension 10 are mirror-symmetrical to each other with respect to a vertical plane passing through the center of the vehicle.

[0029] The axle suspension 10 comprises two elongated guide elements 14, 16, each of which rests on an axle element 18 on one side of the vehicle. The axle element 18 is the front axle of the vehicle. The guide elements 14, 16 are mirror-symmetrical to each other.

Abstract

The invention relates to a pneumatic axle suspension for a vehicle with, disposed on the vehicle sides underneath the frame, guide elements which extend in the direction of travel and rest on an axle element of the vehicle, and whose ends are flexibly connected to the frame by means of articulated suspensions, said guide elements each having a section which faces forwards from the axle element and a section which faces backwards, of which at least one section is contrived to be elastically spring-loaded, and with air bags to support the guide elements with respect to the frame, each air bag being disposed between a guide element and an upper bearing attached rigidly to the frame. One of the two sections of a guide element is contrived as a rigid part, and the other section comprises a leaf spring, whilst the air bags are disposed at the side of the frame and the upper bearing of an air bag is formed by an upper bracket attached to the side of the frame.

Description

[0001] This application is a divisional application of the application dated September 3, 2009, the application number is 200980134607.6, and the invention title is "Pneumatic Axle Suspension for Motor Vehicles". technical field [0002] The invention relates to a pneumatic axle suspension for a motor vehicle comprising a guide element arranged on the side of the vehicle, under the vehicle frame, extending in the direction of travel and resting on an axle element of the vehicle, and, The ends of the guide elements are flexibly connected to the vehicle frame through hinged suspensions, each guide element has a portion protruding forward from the shaft element and a portion protruding rearward, at least one of which is equipped with an elastic spring; The pneumatic axle suspension also has airbags to support the guide element relative to the vehicle frame, each airbag being located between the guide element and an upper mount fixedly fixed to the vehicle frame.
