Description

DESCRIPTION
"STEERING MUDGUARD GROUP OF A FRONT WHEEL OF AN AGRICULTURAL VEHICLE , COMPRISING A LIGHTING DEVICE"
[0001] The present invention relates to a steering mudguard group of a front wheel of an agricultural vehicle , for example a tractor or a small tractor, compris ing a lighting device .
[0002] In particular, in the following description, the term "agricultural vehicle" refers to those vehicles that are typically suitable for moving and operating on agricultural land; the term "tractor" refers to both agricultural tractors , and, more generally, to large machines , such as earthmoving machines derived from agricultural tractors ; in contrast the term " small tractor" refers to the type of vehicles that are typically of compact dimensions , for example used in the viticulture sector, and therefore suitable for harvesting .
[0003] In the prior art , wheeled agricultural vehicles are known that are provided with front steering wheels whereupon respective mudguard groups are arranged . These wheels , when the agricultural vehicle steers , steer in relation to the direction of travel about a steering axis orthogonal to the direction of travel . In the present discussion, as better detailed below, the mudguard groups are steering, i . e . each mudguard group rotates with the relevant wheel thereof about the steering axis .
[0004] The lighting device makes it possible to easily render visible the agricultural vehicle whereupon it is installed and to define the overall dimens ions thereof .
[0005] In order to operate , the lighting device must be properly attached to the steering mudguard group of a front wheel of an agricultural vehicle .
[0006] In fact , detachment of such a device during vehicle motion could cause serious damage . In addition, i f such a device is not stable on the mudguard group, in addition to being a hazard, it could be annoying as it vibrates strongly and would not fully play its role as a result of being displaced from its optimal position .
[0007] There is therefore a strong need to devise a solution for agricultural vehicles wherein the aforesaid issues are resolved . In other words , there is a strong need to provide an agricultural vehicle of which the lighting device is firmly and properly installed on the steering mudguard group .
[0008] The obj ect of the present invention is to provide a steering mudguard group of a front wheel of an agricultural vehicle , comprising a lighting device that solves the aforesaid problems typical of the prior art . In particular, it is the obj ect of the present invention to provide a steering mudguard group comprising a securely and safely attached lighting device .
[0009] This obj ect is achieved by the steering mudguard group claimed in claim 1 and by the agricultural vehicle claimed in claim 10 . The claims that are dependent upon these claims describe preferred variant embodiments involving further advantageous aspects .
[0010] The features and advantages of the lighting device , the steering mudguard group and the agricultural vehicle according to the present invention will appear more clearly from the following description, made by way of non-limiting example according to the appended figures , wherein :
