Detailed Description

The present invention will be described in detail and specifically with reference to the following examples so as to facilitate the understanding of the present invention, but the following examples do not limit the scope of the present invention.

Example 1

The embodiment discloses a sand coating device for an auxiliary brake of a motor vehicle, which comprises a discharge pipe 1, a propelling device 2 and a material box 3. The material box 3 is filled with sand grains for increasing the brake resistance. The propelling device 2 ejects sand grains in the material box 3 to the front of the wheels through the discharge pipe 1, and the top of the material box 3 is provided with a feed inlet 31.

The embodiment is also provided with a bracket 4, and the bracket 4 enables the whole sand coating device to be obliquely arranged, so that the discharge pipe 1 sprays sand grains obliquely downwards to the front of the wheel. The bracket 4 is arranged at the top of the vehicle cover and is provided with anti-abrasion silica gel between the bracket and the cover to prevent the top of the cover from paint removal and peeling. The bracket 4 is detachably connected with the machine cover, so that the sand-coating device is convenient to mount or dismount; the ice-snow protective cover can be installed and used in winter or on occasional ice-snow weather, and can be detached for standby in summer.

The sand-coating device is also provided with an electric control assembly, and a trigger switch 5 is arranged in the carriage. The trigger switch 5 adopts a double-switch structure, wherein one switch is arranged on the vehicle operating platform, and the other switch is linked with the brake pedal. When the weather of rain and snow is met, a switch on the operating platform is turned on in advance; when the electric control assembly detects that the stepping force of the brake pedal is large, sand grains are automatically sprayed to the front of the wheel. When the weather and road conditions are good, the switch on the operating platform is closed, and sand cannot be sprayed even if the brake is applied, namely, the invention can achieve the effect of only using at key time or emergency time. The sand grains of the embodiment are environment-friendly and energy-saving and can be recycled, and the environment is not polluted.
