SU1472333A1 - Vehicle track rolleres suspension - Google Patents

Abstract

The invention relates to tracked vehicles and makes it possible to increase its throughput and stability of movement. In the caterpillar trolley 1, a horizontally movable slider 4 is installed with figured stepped notches 5 in contact with the pushers 6 which rest on the support rollers 3 through elastic elements 7. Depending on the position of the slider 4, the pushers 6 occupy different vertical positions in the notches 5, as a result which the lower branch 13 of the caterpillar takes a concave 14 or convex 15 position. This makes it possible to increase the permeability and stability of the vehicle, depending on the quality of the soil. 2 hp f-ly, 2 ill.

Description

FIG. /

FIELD OF THE INVENTION The invention relates to vehicle construction, in particular to tracked vehicles.

The aim of the invention is to increase the patency and stability of the vehicle.

FIG. 1 schematically shows the suspension of the support rollers of a tracked vehicle; in fig. 2 — node I in FIG. one.

In the caterpillar truck

or get the freedom to move up. The lower branch 13 of the caterpillar 12 from the vertical load applied to it will be located along a convex curve 14. Such a characteristic of the suspension increases the stability of the bulldozer.

When the caterpillar vehicle moves on marshy soils with a bearing ability, the driver with the help of: help of the hydraulic cylinder 9 will put the slider 4 in

the means are set up with the vertical position of the following position (in Fig. 1, this is corresponding to 2, associated with the support rollers 3. There is a movement of the slide 4 to the right).

Then the extreme support rollers 3 will press on the caterpillar 12 with less force, since the corresponding pushers will have freedom of movement upwards, and the central support wheels towards the support rollers 3. full rollers 3 - with greater force, the tick as co. 6 in con fi dent, if they are pushers 6, they will remain at the same level or will be shifted down. Lower branch 13 of the caterpillar 12 from the vertical attached to it

the rod 8c with the control mechanism in the form of a load 20 will be located along the concave hydraulic cylinder 9. curve 15. Such a characteristic of the suspension

A horizontal slider 4 is positioned on the bed 1 and is mounted for horizontal movement. In the slider 4 are figured stepped notches 5,

tact with stepped-shaped notches 5 and elastic elements 7 between the uprights 2 and the pushers 6. The slider 4 is connected

In slider 4, inserts 10 (Fig. 2) can be installed, and rollers II between the pushers and the slider. A caterpillar 12 is mounted around the support rollers on the vehicle, the lower branch 13 of which can occupy position 14 or 15 depending on the movement of the slide 4. Vertical post 2, elastic elements 7 and pushers 6 are located in the vertical guides 16 of the tracked cart 1.

Suspension rollers works as follows.

When the tracked vehicle is moving on solid ground, the driver will use the hydraulic cylinder 9 to set the slider 4 in such a position that all the pushers 6 will be at the same level (this position of the slider 4 is shown in Fig. 1).

Claims (3)

1. Suspension of track rollers of a crawler vehicle, comprising vertical posts associated with support rollers, mounted in vertical guides and spring-loaded with respect to the crawler car by resilient elements arranged in vertical guides, in order to improve flotation and stability vehicle, it is equipped with a horizontal slider and vertical pushers, the slider is installed in a tracked truck with the possibility of a horizon The branch 13 of the caterpillar 12 from the vertical load applied to it will be located in a straight line. When using a tracked vehicle as a bulldozer or excavator. The driver will use the hydraulic cylinder 9 to set the slider 4 to another position (in Fig. 1 this corresponds to the movement of the slider 4 to the left). Then extreme The tugs 40 are mounted in vertical guides in contact with the figured stepped slits of the ram, the resilient elements are mounted between the uprights and the rams, and the slide is connected to the control mechanism. 2. Suspension according to claim. 1, characterized in that The track rollers 3 will press on the tracks - 45 that the slider is provided with inserts, and the figured ones tsu 12 with greater force, due to the shift of the corresponding pushers 6 down, and the central support rollers 3 - with less force, since the corresponding pushers 6 will remain at the same level step cuts are made on the inserts. 3. Suspension on PP. 1 and 2, characterized in that rollers are mounted between the pushers and the slider. or get the freedom to move up. The lower branch 13 of the caterpillar 12 from the vertical load applied to it will be located along a convex curve 14. Such a characteristic of the suspension increases the stability of the bulldozer. When the caterpillar vehicle moves on marshy soils with a bearing ability, the driver with the help of: help of the hydraulic cylinder 9 will put the slider 4 in The next position (in Fig. 1, this corresponds to the movement of the slide 4 to the right). 20 loads will be located along the concave curve 15. Such a characteristic of the suspension thirty 35 raises passability of a caterpillar maschina on marshy soil. x. Invention Formula 1. Suspension of track rollers of a crawler vehicle, comprising vertical posts associated with support rollers, mounted in vertical guides and spring-loaded with respect to the crawler car by resilient elements arranged in vertical guides, in order to improve flotation and stability vehicle movement, it is equipped with a horizontal slider and vertical pushers, the slider is mounted in a crawler car with the possibility of horizontal movement and is configured with shaped stepped notches facing towards the rollers, the pushers 40 mounted in vertical guides in contact with the curly stepped notches slider, the elastic elements are mounted between the uprights and the jacks, and a slider coupled to the control mechanism. 2. Suspension according to claim. 1, characterized in that 45 that the slider is provided with inserts, and curly that the slider is provided with inserts, and curly step cuts are made on the inserts. 3. Suspension on PP. 1 and 2, characterized in that rollers are mounted between the pushers and the slider. 7 ///////////////// FIG. 2
