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.

Example Embodiment

[0013] The present invention will be further described in detail below in conjunction with the drawings:

[0014] Such as figure 1 As shown, the damping-increasing transmission mechanism of the present invention includes a steering wheel shaft 2 connected to the steering wheel 1, a shaft fixing sleeve 3 sleeved on the shaft of the steering wheel shaft 2 through first and second shaft bearings 4, 9, and a shaft fixing sleeve 3 connected with the steering wheel shaft 2 Stepping motor or encoder 11; bakelite damping 5 is provided between the rotating shaft fixing sleeve 3 and the steering wheel shaft 2 to increase the damping. The bakelite damping 5 is ring-shaped and is sleeved on one end of the shaft of the steering wheel shaft 2 through the bakelite fixing key 6. One end of the rotating shaft fixing sleeve 3 is provided with an inner convex surface that matches the end surface of the bakelite damping 5. A spring 7 is also sleeved on the body. One end of the spring 7 bears the ba...

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...
