摘要:
The present invention relates to the drive assembly coupled with the pedal thereon the frame, and the transmission assemblies rotated by the drive assembly. Thereby to step on the pedal repeatedly rotates the transmission assemblies to make the wheel rotate in single direction. Therefore, the invention can first enhance the operating stability and then get the exercise effect while the user kicks the ground to propel the pedal scooter and steps on the pedal repeatedly.

A power assisted vehicle includes an auxiliary propelling device disposed to the frame body. The auxiliary propelling device has an auxiliary wheel and at least one transmission portion disposed in the auxiliary wheel. When two friction wheels of the transmission portion fasten to two sides of a friction ring of the auxiliary wheel, and the two power sources is in reverse to drive the two friction wheels for rotating, a wheel rim and a tire are further driven to produce rotations. The power assisted vehicle is therefore capable of self-propelled going forward without any external force. A processing device is further disposed in the power assisted vehicle. The auxiliary propelling device is then activated when the power assisted vehicle is at a specific speed. The energy consumption for the power sources is then reduced and the service life is extended. The transmission force distribution generated from the power sources is further adjustable. The usage of the power assisted vehicle is more efficient.

A measuring apparatus is provided for measuring the internal friction of a transversely vibrating metal specimen at various operation temperatures. The measuring apparatus includes a container body mounted on a machine table and having an open upper end, an ascending device for moving vertically a container lid into and out of engagement with the container body, and a measuring unit secured to the lower surface of the container lid. The measuring unit includes a measuring rack, a heating body, a heating source, a temperature sensing element, a water-cooled driving member and a water-cooled detecting member. The specimen can be driven by the driving member to vibrate in the measuring unit and detected by the detecting member to allow determination of its metal properties.
