Embodiment Construction

[0061] All features described in detail here can be essential to the invention.

[0062] A leaf spring element 1 is arranged as a so-called spring link in the independent suspension in order to guide the wheel in cooperation with a conventional shock absorber 2 and at the same time reduce its vibration relative to the only partially shown body 6, damping The shock absorber 2 is arranged as usual to reduce the vertical elastic retraction and extension movements of the wheel. The wheels themselves are not shown in the drawings, but only the corresponding independently suspended wheel carrier 3 on which the wheel, not shown, is usually mounted rotatably with an intermediate functional connection of the wheel bearing unit together with exist Figures 1a-3b Visible brake disc 5. exist Figure 3c-4c , the brake disc 5 is basically covered by the brake protection plate 4. In order for the wheels, which are not shown, to also be provided with a reference number, the wheels also us...

Abstract

The invention relates to a single-wheel suspension arrangement of a two-track vehicle, having a lower leaf spring element (1) which is formed from a fiber composite material and which, together with adamper (2) arranged in the manner of a damper strut, performs the wheel control of the vehicle wheel (5) and which is connected at one side to a wheel support (3) and at the other side to an axle support or directly to the vehicle structure (6). Here, the lower leaf spring element (1) is oriented at least approximately in a vehicle transverse direction and has, at the vehicle body side, a supportbase measured in the vehicle longitudinal direction, the length of which support base corresponds to at least 0.4 times the length, measured in the vehicle transverse direction, of the lower leaf spring element (1), and wherein the lower leaf spring element (1) is arranged below the wheel axis of rotation as viewed in a vehicle vertical direction.

Description

technical field [0001] The invention relates to an independent suspension for a double-track vehicle, comprising a lower leaf spring element constructed of fiber composite material and which bears against the wheel with a shock absorber arranged in the form of a spring strut. Guided, the lower leaf spring element is connected on one side to the wheel carrier and on the other side to the axle carrier or directly to the body. Prior art In addition to DE 102013207910 A1 and DE 102014208403 A1 as well as DE 102012221678 A1, reference is also made to DE 102008043330 A1 for forming the preamble of claim 1 . Background technique [0002] One of the simplest and most widely used axles in motor vehicles, especially as the front axle of passenger cars, is the so-called spring strut axle, which consists of a wheel-guided shock absorber, a helical shaft arranged coaxially with the shock absorber The spring and the lower transverse link, which are mostly configured as triangular suspens...
