FR2546109A1 - Suspension joint for a vehicle - Google Patents

Abstract

This joint combining a stabilising bar 10 with a suspension arm 14 of a front wheel comprises a flexible device comprising rubber insulators 16. The insulators are held in place on the bar by retention members 18, 20 and discs 30, 32 made from plastic are interposed between the retention members and the insulators in order to reduce wear. The discs 30, 32 are preferably free to revolve on the bar 10.

Description

The invention relates to a suspension joint

  for vehicle and, more particularly, although not ex-

  clusively, suitable for use between a stabilizer bar and a track control arm of a front wheel suspension.

  According to the invention, a suspension joint is provided.

  vehicle board between a suspension arm and a bar-

  re which passes through an opening in the arm, a joint in which a flexible insulator is provided between the

  bar and the walls of the openings and retaining discs

  nude are mounted respectively on both sides of the iso-

  lator to keep the insulator in position, discs

  made of plastic material being provided between the

outfit and insulator.

  i 5 Plastic discs are preferably

  rence free to turn around the bar and conform

  preferably around the contour of the retaining discs

  read the assembly, the discs may staple on the

  periphery of the retaining members The discs are pre-

  high density polyethylene case.

  Other features and advantages of the

  vention will appear during the description which follows

  vre, with reference to the accompanying drawing, given only as a

  example, which represents a suspension joint according to the

vention seen in partial section.

  A stabilization bar 10 crosses an opening

  ture 12 formed in an arm 14 for controlling the track.

  Flexible rubber insulators 16 are mounted on the bar and enter the opening 12 from each side. A front retaining disc 18 and a rear retaining disc 20 hold in place metal sleeves 22 to which

  the insulators 16 are assembled The assembly is held as-

  appeared on the end of the bar 10 by a lock nut 24.

  The rubber insulators 16 serve to cushion

  the transmission of vibrations from the wheels to the vehicle

  - as the wheels pass over bumps, the rubber breaks

  shape and the flanges 26, 28 can rub against the metal retaining members 18 and 20 and produce

unpleasant noises.

  The interposition of discs 30, 32 in plastic material between the insulators and the retaining members avoids

  this noise satisfactorily Since the dis-

  that can rotate around the stabilization bar 10, the wear of the flanges 26, 28 which normally occurs

  during contact between flanges and return members

  fixed hold 18, 20 is considerably reduced.

  To facilitate assembly, the discs 30, 32 have in spaced positions on their circumference lips 34 which can be snapped over the edges of the retaining members, so that each assembly consisting of a disc and a member restraint can be

  mounted as a single block on the stabilizer bar.

  Table 1 given below shows the results of a study which compared the effectiveness, durability, and the effect on the collars of rubber insulators, of various means with which attempts have been made to reduce

squeaks and wear.
