Hydraulic wheel anti-skid device capable of automatically stretching out

Abstract

The invention discloses a hydraulic wheel anti-skid device capable of automatically stretching out and relates to the field of automobile antiskid devices. The hydraulic wheel anti-skid device comprises a hub. A tire is arranged on the outer side of the hub. Arch protrusions are evenly distributed on the two side faces of the tire. Through holes are punched in the middles of the arch protrusions in the radial direction of the tire. Fixing frames evenly distributed are fixedly connected with the inner side of the hub through screws. Limiting grooves are formed in the two ends of each fixing frame. Two annular hydraulic pipes are arranged in the positions, on the two sides of the hub, of the limiting grooves on the two sides respectively. The outer sides of the two hydraulic pipes are communicated with single-rod piston hydraulic cylinders evenly distributed in a radial shape in the radial direction of the tire, an antiskid supporting rod is installed at the top end of a working rod of each single-rod piston hydraulic cylinder, the other end of the antiskid supporting rod is in a conical shape, and the supporting rods and the through holes of the arch protrusions are connected in a sliding fit mode. The hydraulic wheel anti-skid device has the advantages that the antiskid supporting rods can stretch out to achieve the antiskid purpose through a control system in a vehicle, and the hydraulic wheel anti-skid device is convenient, fast and easy to operate.

Description

technical field [0001] The invention relates to the field of automobile anti-skid devices. Background technique [0002] In the cold season in northern my country, snow often leads to icy roads and other phenomena, resulting in wet and slippery roads. Cars driving on such roads have a low safety factor and are likely to cause traffic accidents. This phenomenon is more serious and occurs frequently, potentially causing serious personal safety hazards and causing tragedies. In order to avoid slippery roads in snowy days and make it difficult for vehicles to drive safely, the traditional method is to add anti-skid chains to the wheels in snowy days, or install some formed anti-skid sleeves to increase the friction between the car tires and the ground, and this tradition The method is time-consuming and labor-intensive to install.

[0002] In the cold season in northern my country, snow often leads to icy roads and other phenomena, resulting in wet and slippery roads. Cars driving on such roads have a low safety factor and are likely to cause traffic accidents. This phenomenon is more serious and occurs frequently, potentially causing serious personal safety hazards and causing tragedies

In order to avoid slippery roads in snowy days and make it difficult for vehicles to drive safely, the traditional method is to add anti-skid chains to the wheels in snowy days, or install some formed anti-skid sleeves to increase the friction between the car tires and the ground, and this tradition The method is time-consuming and labor-intensive to install. It is necessary to add anti-skid devices to the tires when it snows. It is also extremely inconvenient for people to install anti-skid chains in the snow. The installation on the tire is troublesome and time-consuming

Because the weight of the car is all on the wheels, the installation of many anti-skid devices increases the friction, but also increases the wear of the tires and shortens the service life of the tires. The probability of accidental scrapping of tires when the car is running normally will bring unpredictable hidden dangers to the safe driving of the car, leading to serious traffic accidents, etc.

Therefore, the traditional method is time-consuming and labor-intensive, aggravates the wear of the tires, and has potential safety hazards, which is not conducive to the safe driving of the car.
