Abstract
A steering system includes: a steering gear body, where the steering gear body includes a steering gear input shaft and a gear shaft; a decoupling mechanism, where the decoupling mechanism is configured to decouple the steering gear input shaft from the gear shaft or couple the steering gear input shaft to the gear shaft; and a limiting mechanism, where the limiting mechanism is configured to limit a range of a steering angle of the steering gear input shaft, in response to that the steering gear input shaft is decoupled from the gear shaft or that the steering gear input shaft is coupled to the gear shaft.
Claims20
A steering system, comprising:
- a steering gear body, wherein the steering gear body comprises a steering gear input shaft and a gear shaft;
- a decoupling mechanism, wherein;
- the decoupling mechanism is configured to decouple the steering gear input shaft from the gear shaft or couple the steering gear input shaft to the gear shaft;
- the decoupling mechanism comprises a decoupling slide sleeve, a decoupling shaft, and a drive transmission mechanism;
- the drive transmission mechanism is configured to drive the decoupling slide sleeve to translate in an axial direction of the steering gear input shaft and an axial direction of the gear shaft to be engaged with or disengaged from the decoupling shaft;
- and the drive transmission mechanism comprises a first power element configured to provide a driving force, and a transmission reversing component configured to convert a rotary driving force outputted by the first power element into axial translation of the decoupling slide sleeve;
- and
- a limiting mechanism, wherein the limiting mechanism is configured to limit a range of a steering angle of the steering gear input shaft in response to that the steering gear input shaft is decoupled from the gear shaft or that the steering gear input shaft is coupled to the gear shaft.
A vehicle, comprising a steering system comprising:
- a steering gear body, wherein the steering gear body comprises a steering gear input shaft and a gear shaft;
- a decoupling mechanism, wherein;
- the decoupling mechanism is configured to decouple the steering gear input shaft from the gear shaft or couple the steering gear input shaft to the gear shaft;
- the decoupling mechanism comprises a decoupling slide sleeve, a decoupling shaft, and a drive transmission mechanism;
- the drive transmission mechanism is configured to drive the decoupling slide sleeve to translate in an axial direction of the steering gear input shaft and an axial direction of the gear shaft to be engaged with or disengaged from the decoupling shaft;
- and the drive transmission mechanism comprises a first power element configured to provide a driving force, and a transmission reversing component configured to convert a rotary driving force outputted by the first power element into axial translation of the decoupling slide sleeve;
- and
- a limiting mechanism, wherein the limiting mechanism is configured to limit a range of a steering angle of the steering gear input shaft, in response to that the steering gear input shaft is decoupled from the gear shaft or that the steering gear input shaft is coupled to the gear shaft.
