The invention discloses a biomimetic mechanical jellyfish that is driven by shape memory alloy wires, relates to a biomimetic mechanical jellyfish and aims at solving the problems that the existing biomimetic mechanical jellyfishes only simulate jellyfish actions, do not cover devices such as a drive device and the like, and have complex structure and the biomimetic effect that is totally different with the action principle of real jellyfishes. The biomimetic mechanical jellyfish has following structure: an action unit (10) consists of the shape memory alloy wires (12), an elastic body (13), a coating skin (15) and a substrate (16), the substrate (16) and the shape memory alloy wires (12) are fixedly arranged on the elastic body (13), the action unit (10) is coated inside an umbrella-likesoft layer (11), the coating skin (15) covers outside the shape memory alloy wires (12), the substrate (16) and a sealing cover (3) are fixedly connected with a supporting body (2), a power source (7), a control device (5), a communication device (6) and a sinking and floating control device (9) are fixedly arranged on the supporting body (2), and the power source (7) provides electricity respectively to the control device (5), the communication device (6) and the shape memory alloy wires (12). The biomimetic mechanical jellyfish has simple structure, lightness, low production cost, large action range and good biomimetic effect.

The present invention relates to a power-assisted automobile steering system (1). Said steering system (1) has a steering wheel (2) for providing the desired steering angle of the automobile wheels (3), driving dynamics elements (4) for superimposing a correction angle onto the steering angle, said correction angle being determined with a view to increasing the driving stability and / or driving comfort of the automobile, and a power assist drive device (6). The power assist drive device (6) is configured as a variable torque booster in order to keep the performance of the driving dynamics elements (4) approximately constant throughout the speed range of the vehicle, the degree of torque boost (M) depending on the automobile speed (V) and at least one value of the driving dynamics elements (4) that characterises the correction angle.

A shift lever device includes a shift lever having a pivot shaft formed at a base end of the shift lever integrally and a base having an opening formed to allow the shift lever to be inserted into the base and a pair of bearing parts formed so as to lie on opposing sides of the opening. The pivot shaft extends along a direction intersecting with a longitudinal direction of the shift lever. Each of the bearing parts has a bearing hole formed in the bearing part to adjoin the opening, a guide groove formed in the bearing part to communicate with the bearing hole, for introducing the pivot shaft into the bearing hole and a bearing bush which is to be inserted between the pivot shaft and the bearing hole. The bearing bush has a latch hook provided to engage with an interior of the bearing hole. The bearing bush is fitted to the bearing hole on condition that the pivot shaft is being inserting into the bearing hole through the guide groove, so that the shift lever is rotatably supported by the base through the bearing bush.
