Wearable crawler-type snow mobile device and damping control method thereof

Abstract

A wearable crawler-type snow mobile device and a damping control method thereof belong to the technical field of vehicle engineering. The wearable crawler-type snow mobile device comprises a suspension support mechanism, a crawler transmission mechanism, a crawler guiding mechanism, a crawler steering mechanism and a tensioning mechanism; a damper at the front end is connected with a crawler bottom plate and a front guide plate to damp crawler wheels and meanwhile elastically tension crawlers simultaneously, so that a traditional hydraulic tensioning mechanism can be saved; three dampers at the rear are mainly applied to damping the crawler wheels; damping rods on both sides of the rear are used for restricting the motion trail of an upper suspension support during damping, the damping rods are provided with chain transmission tensioning devices to ensure damping and meanwhile guarantee reliability of the crawler transmission mechanism. The wearable crawler-type snow mobile device is simple in structure, easy to maintain and convenient to dismount and mount, saves dismounting of tyres as well as hoisting equipment and can be mounted independently by single person thereby being simple, time-saving and reliable in mounting; the wearable crawler-type snow mobile device can be driven on roads severely and deeply covered by snow to achieve high cross-country capability and low damage to roads and meanwhile be solid and durable.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to a four-wheel drive wearable crawler-type snow driving device and method. Background technique [0002] In extremely cold regions, the inconvenience of transportation has brought great resistance to economic and social development. In countries and regions in severe cold regions, the harsh ice and snow road environment brings a lot of inconvenience to traffic. Due to the special structure and properties of tires, driving on icy and snowy roads may also cause traffic accidents. [0003] In order to better solve this problem, the appearance of snowy off-road tracks brings great convenience to people in severe cold regions. Most of the current snow crawler mechanisms on the market are divided into two types. One is the crawler mechanism similar to the tank crawler. This crawler mechanism has strong mobility in complex landforms, and can form a 360-degree in-...

AI Technical Summary

Problems solved by technology

Most of the current snow crawler mechanisms on the market are divided into two types. One is the crawler mechanism similar to the tank crawler. This crawler mechanism has strong mobility in complex landforms, and can form a 360-degree in-situ rotation and climb over obstacles. It has strong ability and can cross trenches, but it is heavy, consumes a lot of fuel, and it is relatively difficult to guarantee. Once damaged, the off-road ability will be seriously reduced, and it is extremely inconvenient to maintain

The other is the traditional triangular crawler mechanism. The crawler itself has a large weight, many transmission parts and a complex structure, and the original tires of the vehicle need to be completely removed during installation, and the help of lifting equipment is required to install them.

Moreover, the triangular track is also limited by its own structure, the overall load-bearing capacity needs to be improved, the high-speed stability is poor, the overall strength of the track is not high, and it is easy to be damaged when driving at high speed

It is quite difficult for one person to operate, very troublesome and time-consuming
