技术

ROSTA的每一款产品的核心是1944年使用一个外壳开发的原始技术概念,其中包含一个由4根橡皮绳环绕的内正方形。  

The function of a ROSTA rubber suspension?

Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia curae; Aenean porta egestas posuere. Vestibulum nisl nulla, faucibus vel nulla sollicitudin, tincidunt volutpat dolor. Praesent iaculis tortor justo, eget malesuada erat aliquet vel. Nunc congue quam nec urna ultricies, sed finibus urna laoreet. Praesent in quam erat. Mauris sodales rutrum molestie. Aliquam mattis hendrerit quam, quis dictum diam laoreet a. Donec molestie malesuada nulla, sit amet tempor leo consectetur id.

Ambient temperatures the ROSTA element can be used?

Integer lorem ex, molestie in metus eu, faucibus eleifend diam. Praesent elementum elit ac augue vestibulum sagittis. Curabitur quis ullamcorper mauris, eu commodo lacus. Nullam eu fermentum justo, sit amet porttitor magna. Sed faucibus efficitur mi ac molestie. Nam pharetra auctor vulputate. Vivamus in sagittis ligula. Nulla volutpat, erat vel consectetur maximus, dolor nulla cursus sapien, rutrum rutrum ligula eros vitae tortor. Nullam efficitur velit sit amet blandit suscipit. Duis venenatis euismod finibus. Proin id rutrum tortor.

Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. In nec velit ac nisl congue dictum. Curabitur odio nibh, laoreet eget sagittis ac, rutrum ac augue. Etiam a mauris lobortis, lobortis lorem facilisis, volutpat felis. Maecenas ultricies massa et congue rhoncus. Phasellus vitae risus scelerisque, lobortis erat non, dapibus justo. Sed pretium semper egestas. Nullam gravida non dui vitae vulputate. Etiam at nulla neque. Suspendisse scelerisque eros non sagittis tristique. Nulla dui lacus, consectetur ut risus vitae, consequat venenatis ante.

The average lifetime of a ROSTA element?

Aenean non molestie lectus. Suspendisse facilisis, urna in tincidunt semper, felis nulla dictum urna, eget fermentum dui leo et arcu. Vestibulum ex lectus, pretium lacinia tincidunt quis, interdum gravida eros. Quisque dapibus diam dolor, vitae luctus tortor varius vitae. Sed lobortis sagittis enim, eu hendrerit lacus. Interdum et malesuada fames ac ante ipsum primis in faucibus. Morbi nec scelerisque mauris. Aliquam cursus urna nec magna cursus aliquam. Nulla felis elit, luctus a malesuada id, imperdiet eu libero. Fusce aliquam eros sed lacinia convallis. Pellentesque ac tellus sollicitudin, rhoncus diam sit amet, semper ex.

Does it require maintenance?

Etiam nec aliquam ex. Curabitur mattis convallis vestibulum. Maecenas ac mattis nisl, eget rutrum nibh. Integer et massa justo. Integer aliquam nunc dui, non tincidunt velit dapibus a. Sed eu mi dui. Proin sed tempus nisi. Nullam ut viverra ipsum, sed blandit sapien. Suspendisse eget tortor viverra, finibus sem sed, vestibulum massa. Fusce eros ligula, porttitor a tempus finibus, porta et dolor.

它的作用

ROSTA元件采用紧凑设计,具有多种功能。

三合一功能:

一个扭簧
一个枢轴轴承
一个防振支座

操作角度为+/-30度,拥有各种扭矩和尺寸,可用于无数领域。

工作原理

ROSTA橡胶悬架元件主要设计用于扭簧装置,操作角度为±30℃。根据特定功能,转动弹簧装置不仅会产生扭矩。根据具体应用,通常必须考虑附加的径向Fr、轴向Fa和/或径向Mk力。
the particular function, not only torsional moments are generated by pivoting
the spring device. According to the specific application additional radial Fr, axial Fa and / or cardanic Mk forces have usually to be taken in consideration.

质量控制和公差

自1992年12月以来,ROSTA AG已成为一家通过ISO 9001标准认证的开发、制造和分销公司。所有产品都经过定期的功能和质量测试。橡胶嵌件在内部实验室的检测机器上进行了连续的试验和控制,包括肖氏A硬度、压缩变形率、耐磨性、回弹性、抗拉强度、断裂伸长率和老化性能。 

橡胶嵌件的尺寸公差根据DIN 7715标准定义,肖氏A硬度根据DIN 53505标准定义。橡胶悬挂元件的内芯轮廓和外壳应符合相关生产工艺和相应供应商的公差指南(如铸造、挤压、卷边)和单个材料的一致性(如铝铸件、钢管、球墨铸铁件等)。ROSTA橡胶悬架元件产生的扭矩和弹簧挠度在最多±15%的公差范围内,但通常位于更窄的范围内!
inner-core profiles and housings of the rubber suspension elements are subject to the tolerance guidelines of the relevant production process and respective supplier (e. g. cast, extruded, edge rolled) and the individual material consistence (e. g. aluminium casting, steel tube, nodular cast iron part, etc.). The resulting torsional moments and spring deflections of the ROSTA rubber suspension elements are within a tolerance range of ± 15 % at the most, but usually lie in a much narrower range!
