Transmission mechanism capable of increasing damping

Abstract

The invention relates to a transmission mechanism capable of increasing damping. The transmission mechanism capable of increasing the damping comprises a steering wheel rotating shaft, a rotating shaft fixing sleeve and a stepping motor or an encoder, wherein the steering wheel rotating shaft is connected with a steering wheel, the rotating shaft fixing sleeve is arranged on a shaft body of the steering wheel rotating shaft in a sleeved mode through a first rotating shaft bearing and a second rotating shaft bearing, the stepping motor or the encoder is connected with the steering wheel rotating shaft, and a bakelite damping component used for increasing the damping is arranged between the rotating shaft fixing sleeve and the steering wheel rotating shaft. According to the transmission mechanism capable of increasing the damping, the bakelite damping component is arranged between the rotating shaft fixing sleeve and the steering wheel rotating shaft, the spatial size of the transmission mechanism is enabled to be smaller, the damping of steering transmission is increased, the reliability is high, and therefore the technical problem that the steering wheel rotates without external force or the turning force of the steering wheel is small can be solved, and the transmission mechanism is especially suitable for being used as a steering transmission mechanism with the requirements of using the stepping motor or the encoder as a signal output device.

Description

technical field [0001] The invention belongs to the technical field of transmission mechanisms, and relates to a transmission mechanism, in particular to a transmission mechanism with increased damping. Background technique [0002] In the prior art, the steering systems of industrial vehicles are divided into two categories: mechanical steering systems (manual steering systems) and power steering systems according to the energy used for steering. The mechanical steering system completely relies on the physical ability of the operator to control the steering, overcome the steering resistance moment, and realize the angular deflection of the steering wheel. In the power steering system, the energy consumed to overcome the steering resistance torque is provided by the prime mover, and the operator only manipulates the system with a small force to control the steering. At present, many industrial vehicles use electronic steering systems. The prime mover is a stepper motor or a...

Problems solved by technology

In the power steering system, the energy consumed to overcome the steering resistance torque is provided by the prime mover, and the operator only manipulates the system with a small force to control the steering. At present, many industrial vehicles use electronic steering systems. The prime mover is a stepper motor or an encoder. Due to the small rotation resistance of this type of equipment, the steering wheel automatically rotates when the vehicle is running when the ordinary steering transmission mechanism is used, which is not conducive to safe operation.
