Abstract

The invention provides a distribution method of tracked vehicle load wheels and their number, wherein one pair of tensioning wheels is placed in front, and the track will loosen after a long time of operation, and the tensioning wheel can be adjusted to make it suitable for tightness, and the two pairs of supporting pulleys are evenly distributed. 1 pair of tensioning wheels and 1 pair of driving wheels are distributed in the middle of the track to support, and 1 pair of driving wheels is placed behind to help the vehicle climb and overcome obstacles. 4 pairs of road wheels are evenly distributed on the lower side of the track , the pressure of the 4 pairs of road wheels on the ground is evenly distributed, too many road wheels will increase the length of the vehicle, and then increase the weight of the vehicle, which will have a significant impact on maneuverability and protection.

Description

A tracked vehicle road wheel and its number distribution method

technical field

The invention relates to a road wheel and a method for distributing its number, in particular to a tracked vehicle road wheel and a method for distributing its number, and belongs to the technical field of crawler vehicles.

Background technique

Due to the wide application of tracked vehicles, tracked vehicles have become an indispensable part of military and civilian use. However, for soft land, swampy land, and muddy roads with low bearing capacity, how to evenly distribute the gravity of the vehicle is the bearing of the ground. The area is the largest, the uniform distribution force is the smallest, and the running speed is fast. The number of road wheels affects the speed of the vehicle, and when it encounters soft land or swampy land, it will sink and cannot drive normally, but the more road wheels, the probability of failure It will be bigger, the road wheel travel will be smaller, and the ability to overcome obstacles will be worse. Especially now that tracked combat vehicles generally use torsion bars or liquid-pneumatic suspensions that are good for high-speed driving but have a large volume. If there are too many road wheels, it is bound to take up more space in the vehicle to install suspension components.

In view of the above existing problems, it is necessary to study a distribution method of tracked vehicle road wheels and their number.

Contents of the invention

The object of the present invention is to provide a distribution method of tracked vehicle road wheels and their number, which solves the problem that too few road wheels will affect the speed of the vehicle, and the possibility of trapping is high, but the probability of failure will be greater if too many road wheels are loaded. The smaller the wheel stroke, the worse the obstacle-surmounting ability.

The present invention provides a tracked vehicle road wheel and its quantity distribution method, which comprises: 1 pair of tensioning pulleys 1, 2 pairs of support pulleys 2, 1 pair of driving wheels 3, 4 pairs of road wheels 4 and crawler belts 5, Among them, one pair of tensioning pulley 1 is put on the front, and the track will be loose after long-term operation. You can adjust the tensioning pulley 1 to make it tight. The middle crawler belt 5 of 3 plays a supporting role, and a pair of driving wheels 3 is placed behind, which is helpful for the vehicle to climb slopes and overcome obstacles. If the pressure on the ground is evenly distributed, too many road wheels will increase the length of the vehicle, which in turn will increase the weight of the vehicle, which will have a significant impact on maneuverability and protection.

Description of drawings

Fig. 1 is a structural schematic diagram of a tracked vehicle road wheel and the distribution method of the number;

1. Refer to Fig. 1, a kind of distribution method of tracked vehicle load wheel and its quantity of this embodiment, its composition comprises: 1 pair of tensioning pulleys 1, 2 pairs of support pulleys 2, 1 pair of driving wheels 3, 4 pairs of load bearing wheels Wheel 4 and crawler belt 5, in which one pair of tensioning pulley 1 is put on the front, and the crawler belt will be loose after long-term operation, and the tension can be adjusted by adjusting tensioning pulley 1, and the two pairs of supporting pulleys 2 are evenly distributed in one pair of tensioning pulleys. Wheels 1 and 1 play a supporting role on the middle track 5 of the driving wheel 3, and one pair of driving wheels 3 is placed behind to help the vehicle climb slopes and overcome obstacles. Four pairs of road wheels 4 are evenly distributed on the lower side of the track 5 , the pressure of its 4 pairs of road wheels 4 on the ground is evenly distributed, too many road wheels will increase the length of the vehicle, and then increase the weight of the vehicle, which will have a significant impact on maneuverability and protection.
