Problems solved by technology

[0005] However, although the above two steering systems can satisfy the safety and ease of operation, due to the complex structure of the steering system using the double planetary gear set, the processing is difficult, the technical precision is high, the cost is also high, and the noise during operation is large. , reducing the overall comfort of the vehicle; and the steering system using the harmonic gear structure has high requirements on materials and processing technology, and also has the problem of high cost. Therefore, these two steering systems have not been popularized, which is obviously incompatible with The current popularity of vehicles does not match

Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0032] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and examples.

[0033] First, in order to solve the above-mentioned technical problems existing in the prior art, the present invention provides a method for changing the steering gear ratio, which can change the steering gear ratio accordingly according to the driving conditions of the vehicle, so as to provide more labor-saving and safer steering .

[0034] Specifically, the steering transmission ratio control method of the present invention includes engaging the outer peripheral surface of the variable ratio drive wheel with the disc surface of the variable ratio turntable for outputting steering power, so that the variable ratio drive wheel drives the variable ratio turntable when rotating R...

Abstract

The invention belongs to the technical field of vehicle steering and provides a steering transmission ratio control method and control device, a steering system and a vehicle. The vehicle steering transmission ratio control method comprises the steps that the peripheral surface of a ratio-varying driving wheel is connected with the table face of a ratio-varying turntable used for outputting steering power, so that the ratio-varying driving wheel drives the ratio-varying turntable to rotate when rotating; and the distance between the central axes of the ratio-varying driving wheel and the ratio-varying turntable is adjusted in the radial direction of the ratio-varying turntable to change the transmission ratio, accordingly, the transmission ratio is changed correspondingly according to different driving conditions, and convenient, rapid and safe steering is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle steering, in particular to a steering transmission ratio control method capable of changing vehicle steering force, a steering transmission ratio control device, a steering system and a vehicle. Background technique [0002] At present, with the popularization of vehicles, consumers' requirements for vehicle safety and handling comfort continue to increase. Steering system is one of the most core systems in vehicle handling performance, and it is also one of the important factors of vehicle safety. Consumers' requirements for steering control of vehicles have also increased, that is, it must be convenient and safe. [0003] For this reason, various vehicle manufacturers have carried out a large amount of systematic research and development on the steering system. For example, there is an existing steering system that uses two sets of planetary rows to achieve steering angle superposition, and ano...
