CENTRAL ELEMENT FOR HYDROSTATIC TRANSMISSION'S SPEED CONTROL

摘要

The central element of the speed control consists of the body (1), which is equipped with the left cover (2) and right cover (3), where the input space (11), which connects with the input opening (14), and the output space (13), which connects with the output opening (15), are created. The cone (5) is placed in the input space (5) and it is moveably mounted and equipped with the screen (6), which connects the input space (11) with the outer space (13). The spring (8) is located in the outer space (13) and it leans against the cone (5) by it one end. The goal of the solution is the fact that the second end of the spring (8) leans against the stop piece (7), which is moveably mounted in the output space (13) and the input space (11) is connected with the output space (13) by means of the by-pass channel (12). The so created central element of the speed control enables to set programme parameters of the machine micro-travel directly without the need of other additional devices. Moreover, some parts of the commonly produced pressure valve can be used for its production.<IMAGE>
