Problems solved by technology

Although the dynamics of the vehicle in response to the driver's inputs can be simulated or measured, this understanding does not address the issue of 'good handling' unless it is based on an understanding of how the human as a control system and the driver's brain work in vehicle control understanding to supplement

Embodiment Construction

[0044] figure 1 The dynamics of a motor vehicle with six degrees of freedom named as follows are disclosed:

[0045] movement up and down = ups and downs;

[0046] movement left and right = swing;

[0047] Before and after exercise = surge;

[0048] Angular change about horizontal lateral axis Y = pitch;

[0049] Angular change about vertical axis Z = yaw; and

[0050] Angular change about the horizontal longitudinal axis X = roll.

[0051] figure 2 A motor vehicle is disclosed comprising a body 1 and an engine-transmission system 2 comprising an engine 3 and a transmission comprising a number of different drive shafts 4 . In the disclosed embodiment, the engine 3 is provided at the front of the motor vehicle. The motor vehicle has two wheel suspension systems, a front wheel suspension system for the front wheels 5a, 5b and a rear wheel suspension system for the rear wheels 6a, 6b. The propeller shaft 4 connects the transmission 3 to the wheels 5a, 5b, 6a, 6b using d...

Abstract

A rear wheel suspension for a motor vehicle comprises first and second suspension devices (8a, 8b) carrying a right and left, respectively, rear wheel rotating in a wheel plane forming a toe angle (delta) with respect to a longitudinal axis (X) and a camber angle (gamma) with respect to a vertical axis (Z). A transversal beam (10) connects the first suspension device (8a) and the second suspension device (8b). Each suspension device comprises a wheel spindle housing (11a, 11b), defining a wheel centre, and a leading link (14a, 14b) and a trailing link (15a, 15b) connected to the vehicle body. The transversal beam permits bending for vertical loads to provide the suspension devices a deflection to adjust the toe and camber angles such that the changes of the camber angles when the wheel planes converge towards an upper point above the wheel centre connect to a controlled adjustment of the toe angles such that the wheel planes converge directionally towards a rear point located rearwards of the wheel centre.

Description

technical field [0001] The present invention relates generally to suspension systems for the rear wheels of motor vehicles, especially passenger cars, sport utility vehicles (SUVs) and light trucks. More particularly, the invention relates to a rear wheel suspension system as defined in the pre-characterizing part of claim 1 . The invention also relates to a motor vehicle comprising such a rear wheel suspension system. Background technique [0002] The rear wheel suspension system of a motor vehicle connects the framework of the sprung vehicle mass to the framework of the unsprung and rotating rear wheels and associated tires (rear tire-wheel assembly). In addition, the rear wheel suspension system responds to external impacts from the road and to propulsion, braking and steering forces such as initiated by the driver through the engine-transmission system, braking system, steering system and rear and front wheel suspension systems. Internal shocks, which control the sport...
