Abstract
A bell crank is pivotally mounted on a suspension link. One end of the bell crank is connected with an essentially horizontal shock absorber while the other is connected with a pull rod. As the road wheel undergoes vertical displacement the bell crank rotates while also undergoing vertical displacement along with the link it is mounted on. The lever ratio established between the shock absorber and the link thus changes.
Claims8
A vehicle suspension comprising:
- a link, said link having an inboard end pivotally connected to a vehicle chassis and an outboard end pivotally connected to a road wheel;
- a bell crank pivotally mounted on said link;
- a shock absorber, said shock absorber having one end pivotally connected to the vehicle chassis and a second end pivotally connected to said bell crank;
- and
- a pull road, said pull rod being pivotally connected at one end to the chassis and pivotally connected at a second end to said bell crank.
2 more elements
A vehicle suspension comprising:
- a first link operatively interconnecting a road wheel and a vehicle chassis;
- a second link operatively interconnecting the road wheel and the vehicle chassis, said second link being arranged below said first link;
- bell crank means pivotally mounted on said first link;
- a shock absorber, said shock absorber being pivotally connected at an inboard end to the vehicle chassis and at an outboard end to said bell crank means, said shock absorber having a spring which applies a bias to said bell crank means in a manner which tends rotate said bell crank means in a first rotational direction;
- and
- a pull rod, said pull rod being arranged to interconnect the bell crank means and the vehicle chassis in a manner which restrains the bell crank means against rotation due to the bias of the spring.

A vehicle suspension comprising:
- a first link operatively interconnecting a road wheel and a vehicle chassis;
- a second link operatively interconnecting the road wheel and the vehicle chassis;
- bell crank means pivotally mounted on said first link by way of a first pivot;
- a shock absorber, said shock absorber being pivotally connected at an inboard end to the vehicle chassis and at an outboard end to said bell crank means by way of a second pivot, said shock absorber having a spring which applies a bias to said bell crank means in a manner which tends to rotate said bell crank means in a first rotational direction;
- and
- a pull rod, said pull rod having an outboard end connected to said bell crank means by way of a third pivot and an inboard end connected to the vehicle chassis, the first, second and third pivots being so arranged that the bias which is applied to the bell crank by the spring of said shock absorber subjects the pull rod to a constant tensile force.
3 more elements
A vehicle suspension comprising:
- a link, said link having an inboard end pivotally connected to a vehicle chassis and an outboard end pivotally connected to a road wheel;
- A bell crank pivotally mounted on said link;
- a shock absorber, said shock absorber having one end pivotally connected to the vehicle chassis and a second end pivotally connected to said bell crank;
- and
- a pull rod, said pull rod being pivotally connected at one end to the chassis and pivotally connected at second end to said bell crank, said shock absorber and said pull rod defining means which constantly subjects said pull rod to a tractive force and prevents the application of compressive forces therealong.
