Description

TECHNICAL FIELD

The invention relates to units and components of a kart microcar, in particular, to an adjustable pedal assembly of a kart microcar.

BACKGROUND OF THE ART

An adjustable pedal assembly for microcars is known, disclosed in EP 2987047 A1, publ. 02/24/2016. The pedal assembly is slidably mounted on a beam rigidly connected to the chassis, so that the distance between the pedal assembly and the accelerator pedal of the seat can be adjusted.

The disadvantage of the technical solution disclosed above is:

- one pedal fulcrum, i.e. the pedal rotates on an axis fixed only on one side, while the other side hangs in the air, which also negatively affects the reliability of the structure and accelerates wear;

- lack of bearings on which the mechanism moves, which negatively affects the reliability of the structure and accelerates wear.

In addition, an adjustable pedal assembly for microcar karts is known from the prior art, disclosed in CN 207328146 U, publ. 05/08/2018, prototype. The adjustable pedal assembly contains a movable base (1), which moves using linear bearings (10) along guides (11) installed in the frame (8). In this case, the brake (2) and gas pedals (3), as well as the position lock (4) of the movable base, are fixed to the movable base (1).

The disadvantage of the technical solution disclosed above is:

- the location of the runners between the pedals in the middle of the assembly, which leads to increased wear due to the large forces created (large lever for applying the load) when pressing the gas and brake pedals.

- the absence of dampers that prevent the frame from being “pinched” by the rigid frame of the pedal assembly, which absorb and dampen sudden loads that occur when the foot hits the pedals (this is especially true for the brake pedal when using the machine in amateur and sports competitions);

- the pedals move separately from the mechanisms that they operate (the main brake cylinder and the gas mechanism), therefore, when moving the pedals, the length of the rods/cables and other things that connect them must change, which ultimately leads to a more complex design;

- one pedal fulcrum, i.e. the pedal rotates on an axis fixed only on one side, while the other side hangs in the air, which also negatively affects the reliability of the structure and accelerates wear.

DISCLOSURE OF INVENTION

The objective of the claimed invention is to develop a pedal unit for a go-kart microcar that can be adjusted to the height of the user.

The technical result of the invention is to increase the reliability of the design while ensuring convenience and safety of driving.

The specified technical result is achieved due to the fact that the adjustable pedal assembly for microcar karts contains a steel frame with runners attached to the edges of the frame and on which a movable platform with linear motion bearings is fixed, made with the possibility of reciprocating movement inside the steel frame, while the steel frame equipped with damping elements.

The movable platform has a platform position lock inside the steel frame using a plate with adjustment holes.

The movable platform is equipped with a brake pedal and a gas pedal, fixed at at least two support points.

The brake pedal is connected to a brake cylinder mounted on a movable platform.

The gas pedal is connected to a plate for supplying the gas cable, installed on a movable platform to the right of the gas pedal.

IMPLEMENTATION OF THE INVENTION

The adjustable pedal assembly for microcar karts contains a steel frame (1) with runners (3) attached to the edges of the frame (1). A movable platform (4) with bearings (9) of linear movement is fixed on the runners (3), made with the possibility of reciprocating movement inside the steel frame (1), while the steel frame (1) is equipped with damping elements (2) - any known from the level technical elements, for example, rubber buffers.

On the movable platform (1) there is a clamp (10) installed for the position of the platform inside the steel frame (1) using a plate (11) with adjustment holes fixed to the frame (1).

The movable platform is equipped with a brake pedal (6) and a gas pedal (7), fixed at at least two support points.

The brake pedal (6) is connected to the brake cylinder (5) installed on the movable platform (4).

The gas pedal (7) is connected to a plate (8) for supplying the gas cable, installed on a movable platform (4) to the right of the gas pedal (7). The gas pedal (7) and the gas cable supply plate (8) are installed next to each other. The throttle cable jacket is attached to the plate (8), and then the throttle cable itself is attached to the pedal (7).

The claimed node works as follows. The pedal assembly assembled on the frame is installed and fixed inside the frame (12) of the kart microcar, so that the damping elements (2) are in contact with the frame (12) of the kart microcar. The pilot sits down in the go-kart microcar and adjusts the location of the pedal assembly inside the steel frame (1). To make adjustments, the pilot loosens the lock (10) and moves the movable platform (4) with the elements of the pedal assembly installed on it away from himself or towards himself (depending on the height of the pilot), after which he fixes the movable platform (4) in the selected position by tightening the lock . To loosen the latch (10), it is rotated counterclockwise, thereby the cylinder of the latch (10) comes out of the holes of the plate (11), to tighten the latch (10), it is rotated clockwise, thereby the cylinder of the latch (10) comes out of the holes of the plate (11 ). The plate (11) is equipped with many holes, which will allow the movable platform (4) to be fixed in several different positions. After turning on the engine, the pilot presses the gas pedal (7), on which the gas cable is attached, and which is located next to the plate (8) for supplying the gas cable and securing the cable jacket, thereby adjusting the speed of the micro-kart vehicle depending on the depth of pressing the gas pedal . To stop the kart microcar, the pilot presses the brake pedal (6), which is connected to the main brake cylinder using a rigid steel rod. During the process of piloting a kart microcar, damping elements (11) dampen sudden loads that occur when the foot hits the pedals, which, compared to the state of the art, ensures increased reliability of the design of the pedal assembly, therefore, extends its service life and ensures driving safety.

In the claimed invention, the placement of the gas pedal and the plate for supplying the gas cable, the brake pedal and the brake cylinder on the movable platform, as well as their connection to each other, ensures that these elements remain immovable relative to each other when the movable platform moves, thereby allowing the length of the rods/cables not to change and other components that connect them, that increasing the reliability of the design of the pedal assembly, therefore, extends its service life and ensures driving safety, due to possible wear in contact with other components of the microcar cards due to changes in length.

The location of the runners in the claimed invention increases the reliability of the design of the pedal assembly, therefore, extends its service life and ensures driving safety, because Compared to the state of the art, the arrangement of the runners along the edge of the frame makes it possible to reduce bearing wear due to a reduction in the load from the elements of the pedal assembly due to a smaller lever for applying the load when pressing the gas and brake pedals.

Fixing the gas and brake pedals at at least two points of support on a movable platform, compared to the prior art, makes it possible to eliminate sagging of one side of the pedal in the air, from which it is known that the pedal rotates on an axis fixed only on one side, while the other side hangs in the air, which also negatively affects the reliability of the structure and accelerates wear, and also reduces driving safety.

The invention has been described above with reference to a specific embodiment thereof. Other embodiments of the invention that do not change its essence as disclosed in this description may be obvious to those skilled in the art. Accordingly, the invention should be considered limited in scope only by the following claims.
