FIELD: transport.SUBSTANCE: group of inventions relates to options of suspension assembly design, to tracked vehicle, snowmobile and rear suspension assembly. Suspension assembly comprises two rails, the first suspension arm, the second suspension arm, and the swinging arm. Part of the second suspension arm is connected to rails, and a ball hinge connects the lower end of the second suspension arm to the upper end of the swinging arm. According to one option, the assembly can contain at least one shock absorber connected between the chassis and rails, according to another option - at least one damper and at least one spring. Vehicle and snowmobile comprise a chassis, an engine, a caterpillar and one of the options of the suspension assembly. Rear suspension assembly comprises a suspension arm, a swinging arm. Suspension arm has one first position, in which the first transverse axis is parallel to the second transverse axis, and one second position, in which the first transverse axis is inclined towards the second transverse axis.EFFECT: there is achieved smooth run due to the suspension assembly design.18 cl, 9 dwg |
