Hydraulic damping device for direct-drive bicycle riding platform

Abstract

The invention discloses a hydraulic damping device for a direct-drive bicycle riding platform, and relates to the technical field of physical training instruments. The damping device for the direct drive type bicycle riding platform is composed of a liquid resistor used for generating damping, a mechanical transmission mechanism used for driving the liquid resistor and a cooling device used for heat dissipation of the liquid resistor, wherein a casing, an O-shaped sealing ring, a resistance wheel shaft, an impeller, a bearing seat, a built-in flywheel, a resin plate and a fastening ring form the liquid resistor used for generating damping, damping oil is injected into the casing, the O-shaped sealing ring is placed in a casing sealing groove, and the fastening ring is connected with the casing through a bolt. According to the invention, a hydraulic damping technology is adopted; the connection of power supply is not needed, the device is wide in application range and free of electromagnetic noise, a transmission component capable of generating damping is sealed in a sealed oil cavity, the casing has the smooth characteristics of noise isolation, more silence and hydraulic damping,and due to the inertia effect of an internally-arranged external flywheel and the built-in flywheel, the riding feeling is smoother.

Description

technical field [0001] The invention relates to the technical field of sports training equipment, in particular to a liquid damping device for a direct-drive bicycle riding platform. Background technique [0002] The damping technology of existing direct-drive bicycle riding platforms is mostly electromagnetic damping devices. The hydraulic damping technology has been used in the field of friction-type riding platforms, but it has just started to be shipped to foreign countries for direct-drive bicycle riding platforms. It is basically blank in China. The working principle of the electromagnetic damping device is: change the electromagnetic intensity by changing the current of the electromagnetic coil, thereby controlling the damping size. This type of damping device has the following defects: it needs to be connected to the mains, and it is only suitable for power supply. The place requires additional energy consumption, the site is limited, and it is not low-carbon and env...
