Description

The invention relates to wheeled transport equipment and can be used in the field of its operation to improve the efficiency of protection against splashing water and dirt from under the wheels.

The purpose of the invention is to improve work efficiency and expand operational capabilities.

FIG. 1 - general view of the mudguard; in fig. 2 - section A-A in Fig. 1; in fig. 3 section b-b in fig. 1; in fig. 4 - belt for adjusting the position of the lower edge of the elastic element; in fig. 5 is a view of a mudguard with fan-shaped sections of an elastic element.

The mudguard of a wheeled vehicle (Fig. 1) contains a rigid protective element 1 having horizontal plates P on both sides, an elastic protective element 2, consisting of a longitudinal section C and sections D and E located at angles relative to section C 1 and ar, respectively. Sections C, D and E of element 2 are made with horizontal parallel corrugations a. Element 1 is fixed to the wing 3 of the vehicle with the help of the upper 4 and two lower BIBs of door locks. The lower edge in the elastic protective element 2 is connected to the rigid element 1 by means of an adjusting device 7, consisting of an elastic belt 8 (Fig. 4) with holes, and a buckle 9, through which the belt 8 is pulled and fixed. The belt 8 is passed through the holes d, made in the corrugations a of the longitudinal section C of element 2.

As a variant of the mudguard, the corrugations in the section D of the element 2 are made fan-shaped with the center at point O (Fig. 5).

The mudguard works as follows. Before driving, the driver, in accordance with the static deflection of the suspension of each wheel and the upcoming road conditions (the degree of wear of the road surface, the level of precipitation, etc.), sets the distance from the edge in the elastic protective element 2 to the supporting surface using the adjusting device 7. During the movement of the vehicle, the protective rigid element 1 and sections C, D and E of element 2 form in three directions obstacles in the path of the propagation of splashes of water and dirt escaping from the contact zones of the wheels with the road, ensuring the protection of pedestrians, objects located along the road, and the surfaces of the vehicle itself, water and liquid mud settling on the mudguard flows down the corrugations of element 2 back onto the road. Sections D and E of element 2, located at the angles ay and ar, direct the main part of the air flow entering the wheel housing while driving, bypassing it, while reducing the removal of spray from the niche due to turbulent phenomena.

The proposed design of the mudguard provides a large social effect, allowing in urban conditions to increase the efficiency of pedestrian protection from splashing water and mud from under the wheels of vehicles. The economic effect is achieved by reducing the cost of cleaning and washing both the outer surfaces of the vehicle itself and items located along the road.

If access to the wheel and suspension elements is required, the driver opens the locks located on the rigid protective element and removes the entire mudguard from the wheel housing.

Claims (4)

Claim· 1. Mudguard of a wheeled vehicle, containing a rigid protective element vertically installed along the wheel, the surface of the upper and side edges of which is made with the possibility of abutting the surface of the outer edge of the wheel housing, and the surface of the lower edge is located at the level of the vehicle bottom, an elastic protective element, including vertical longitudinal and transverse flaps, the last of which are installed in front and behind the wheel, and connected to the lower surface of the rigid protective element with the possibility of movement, it relates to the lower edge of at least one of the said flaps, and the means for fastening the rigid protective element to the vehicle body, characterized by the fact that, in order to increase efficiency in work and expand operational capabilities, a horizontal flanging is made in the lower part of the rigid protective element, located outside the boundaries of the wheel housing and with its upper surface adjacent to the bottom of the body, and on the lower surface, a bearing elastic protective element, the longitudinal and transverse flaps of which are made at the same time corrugated in height on their entire surface, and the means for fastening the rigid protective element are made in the form of at least three locks, one of which is located in the upper part of the element, and two others - at the bottom, on opposite sides. 2. Mudguard for π. 1, distinguished by the fact that the adjustment of the position of the lower edge of the elastic element is carried out by means of an elastic belt, one end of which is rigidly connected with the lower edge of the elastic element, and the other end with a rigid protective element using a detachable connection with discrete fixation belt on any part along its entire length. 3. Mudguard according to claim 1, on the other hand. that the longitudinal section of the elastic protective element is made with parallel corrugations, and on the transverse sections the corrugations are fan-shaped around the centers located inside the track 5 of the vehicle, and are made with variable lengths. 4. Mudguard pop. 1, which is refined in that the outer surfaces of the front and rear transverse sections of the elastic protective element are located at acute angles to the plane of the longitudinal flap of this element.
