Abstract

Изобретение относится к машиностроению и может быть использовано при производстве и эксплуатации амортизаторов. Задачей изобретения является улучшение демпфирующих свойств амортизатора, при этом амортизатор транспортного средства содержит гильзу, поршневую крышку, штоковую крышку, шток и поршень, выполненные с возможностью совместного продольного перемещения, и гильза выполнена таким образом, что в области или областях, прилегающих к крышкам амортизатора, внутренняя полость гильзы по длине области гильзы содержит по крайней мере два участка, и на каждом из участков внутренний диаметр гильзы по длине участка (в направлении от поршневой крышки к штоковой крышке) уменьшается до величины минимального внутреннего диаметра гильзы на этом участке, а затем увеличивается до величины максимального внутреннего диаметра гильзы этом участке. Технические результаты: существенное увеличение силы, противодействующей движению поршня в гильзе в областях, прилегающих к крышкам амортизатора; задействование двух боковых поверхностей уплотнения при движении поршня в этих областях.The invention relates to mechanical engineering and can be used in the manufacture and operation of shock absorbers. The objective of the invention is to improve the damping properties of the shock absorber, while the vehicle shock absorber contains a liner, a piston cover, a rod cap, a rod and a piston, which are made with the possibility of joint longitudinal movement, and the liner is designed so that in the region or areas adjacent to the shock absorber caps the inner cavity of the liner along the length of the liner region contains at least two sections, and in each of the sections the inner diameter of the liner along the length of the section (in the direction from the piston cover to the current cover) is reduced to the value of the minimum internal diameter of the sleeve in this area, and then increases to the value of the maximum internal diameter of the sleeve in this area. Technical results: a significant increase in the force opposing the movement of the piston in the sleeve in the areas adjacent to the shock absorber caps; engaging the two side surfaces of the seal when the piston moves in these areas.
