[0002] Pedal device

[0003] The invention relates to a pedal device with a pedal having a pedal body and a pedal cap arranged at one end of the pedal body and provided with a tread area forming a free end of the pedal, a pedal holder on which the pedal body is mounted so as to be movable in an axial direction, and at least one pedal spring which is connected between the pedal holder and the pedal body and against whose spring force the pedal body is movable in the axial direction relative to the pedal holder, preferably towards the pedal holder.

[0004] DE 198 36 691 A1 discloses a pedal device for electrically actuated motor vehicle brakes, comprising a pedal body that is translationally movable in the actuation direction and is subject to the force of a spring acting as a return means that counteracts the actuation direction and preferably has a linear characteristic. The pedal body has a contact means that converts at least one linearly increasing actuation travel increment into progressively increasing spring travel increments and imprints them on the adjacent spring. A cam with a defined, non-linear cam contour is provided as the contact means. At the foot-side end, the pedal body comprises a thickened cap, to which a shaft is connected, the end of which is acted upon by a return spring.

[0005] A disadvantage of known linear pedal devices with electronic pedal actuation detection is that the return spring's travel is short and its spring stiffness is high. This serves to keep the pedal device compact overall, while the sensors used for electronic pedal actuation detection generally have a short detection travel. However, the resulting short pedal travel can be confusing for the driver, who is accustomed to relatively long pedal travels with conventional, pivoting pedals.

[0006] Based on this, the invention is based in particular on the object of increasing the pedal travel in a linear pedal device, but still being able to keep it compact.

[0007] This object is achieved according to the invention by a pedal device according to claim 1. Preferred developments of the invention are given in the subclaims and in the following description.

[0008] A pedal device with a pedal having a pedal body and a pedal cap which is arranged at one end of the pedal body and is provided with a tread area which forms a free end of the pedal, a pedal holder on which the pedal body is mounted so as to be movable in an axial direction, and at least one pedal spring which is connected between the pedal holder and the pedal body and against whose spring force the pedal body can be moved in the axial direction relative to the pedal holder, preferably towards the pedal holder, is further developed according to the invention in particular in that a spring means is provided between the tread area and the pedal body, against whose spring force the tread area can be moved in the axial direction relative to the pedal body, preferably towards the pedal body.

[0009] The spring means is connected, in particular, in series with the at least one pedal spring. This results, for example, in a lower spring stiffness and / or an increased pedal travel between the tread area and the pedal holder. Furthermore, by providing the spring means between the tread area and the pedal body, an enlargement of the pedal holder, which is usually designed as a housing, can be avoided. Integration of the spring means into the pedal cap is also possible. The compactness of the pedal device can thus be maintained.

[0010] The pedal body and / or the at least one pedal spring is preferably assigned a longitudinal axis extending in the axial direction, which preferably runs centrally through the pedal body and / or through the at least one pedal spring. One or any direction extending transversely to the longitudinal axis and / or transversely to the axial direction is referred to in particular as a radial direction. A direction extending around the longitudinal axis is preferably referred to as the circumferential direction. The expression "at least one" advantageously also encompasses the meaning of "one" or "exactly one."

[0011] The pedal body preferably extends in the axial direction. The pedal body is preferably elongated in the axial direction. Advantageously, the pedal body is a tube or a rod. The pedal body can also be referred to as a shaft, for example. The end of the pedal body at which the pedal cap is arranged is also referred to in particular as the pedal cap-side end of the pedal body. Preferably, the pedal cap-side end of the pedal body is an axial end of the pedal body. Advantageously, the pedal cap-side end of the pedal body is an end of the pedal body facing away from the pedal holder. Preferably, the pedal cap is firmly connected to the pedal body and / or to the pedal cap-side end of the pedal body. The pedal body is in particular a dimensionally stable body. For example, the pedal body is a rigid body. Preferably, the pedal body is made of plastic and / or metal.For example, the pedal body is guided on the pedal holder so as to be displaceable in the axial direction. A preferably axial position of the pedal body which occurs when the pedal device is not actuated is referred to in particular as the pedal body's rest position. The pedal holder is preferably a housing which can also be referred to, for example, as a pedal housing. In particular, the pedal holder comprises an interior space. Preferably, the at least one pedal spring is arranged in the pedal holder and / or in its interior space. Advantageously, the pedal body extends into the pedal holder and / or into its interior space. Preferably, the pedal cap and / or the pedal cap-side end of the pedal body is provided outside the pedal holder and / or its interior space.

Preferably, the pedal body is guided so that it can move in the axial direction by the at least one pedal spring, in particular on or in the pedal holder. For example, the mobility of the pedal body, in particular by the at least one pedal spring, is limited to only one dimension, preferably relative to the pedal holder. This dimension is determined in particular by the axial direction.

[0013] The at least one pedal spring does not, for example, comprise a helical spring.
