Description

[Detailed Description of the Invention] This invention relates to an improvement of a suspension system for a tracked combat vehicle.

Conventionally, tracked combat vehicles that run on tracks have a torsion bar a as shown in Figure 1.
A plurality of rolling wheels b are provided which are more suspended. Toshiyonba a that suspends these wheels b
In order to increase the movement of each wheel b in the vertical direction, wheels that are approximately the full width of the vehicle are installed so as to be shifted back and forth. For this reason, the center of rotation of left and right wheels b is also shifted, so the longitudinal arrangement of left and right wheels b does not match left and right, and since left and right wheels b are independent, the roll angle of the vehicle body is large and stable when turning. There was a problem with the quality of the product.

This invention was made for the purpose of improving this problem, and it provides a suspension system for combat vehicles in which the left and right wheels are arranged in the same direction in the front and back directions, and the left and right wheels are linked by a stabilizer mechanism. The aim is to improve the stability of

This invention will be explained in detail below with reference to an embodiment shown in Figure 2 and below. In the figure, the body of a tracked combat vehicle has a starting wheel and an idler wheel (not shown) on both sides, and a plurality of wheels installed between these wheels. The vehicle has a suspension A consisting of two wheels 2, the driving wheel, the idler wheel, and an endless crawler belt 3 wrapped around each wheel 2. Each of the above-mentioned wheels 2 is rotatably supported at the tip of a wheel arm 4 installed in the same left and right arrangement, and moves in the vertical direction around a support shaft 4a of the wheel arm 4 supported on the vehicle body 1 side. It is designed to be able to swing. Further, the mutually opposing support shafts 4a of the wheel arm 4 are connected to each other by a stabilizer torsion bar 5 having a relatively small spring constant, and a serration 4b is formed on the outer peripheral surface of each support shaft 4a. The base end side of the lever 6 is engaged with these serrations 4b.

On the other hand, suspension torsion bars 7 are placed in front and behind the stabilizer torsion bars 5 in parallel with the stabilizer torsion bars 5.
are installed, and one end side of these torsion bars 7, that is, the end opposite to the rolling wheels 2 to be suspended, is fixed to the vehicle body 1 via a bracket 8, and the other end side of each suspension torsion bar 7 is fixed to the vehicle body 1 via a bracket 8. The proximal end side of the lever 9 is engaged with the serration 7a. The tip of this lever 9 and the lever 6 provided on the support shaft 4a of the wheel rolling arm 4 are connected to each other by a connecting rod 10.

As described in detail above, this invention has wheels 2 installed on both sides of the vehicle body 1 so as to be arranged in the same manner on the left and right sides.
Since the suspension is carried out by suspension torsion bars 7 provided before and after the stabilizer torsion bar 5, the same vertical movement of the rolling wheels 2 as in the past can be obtained, and the movement of the rolling wheels 2 on one side is controlled by the suspension torsion bars 5. Since it is transmitted to the opposite side through the vehicle body 1, even when the vehicle body 1 turns, the roll angle does not become large and stable turning is possible. Also rolling wheels 2
By making the left and right arrangements equal, the left and right suspension circumferences A become symmetrical, which also has the effect of increasing the compatibility of each part and making manufacturing easier.
