All-terrain vehicle and steering system thereof

Abstract

The invention discloses an all-terrain vehicle and a steering system thereof. The steering system comprises a steering wheel, a steering power assisting device, a steering cross shaft assembly, a steering column pipe and a steering gear box, wherein the steering power assisting device is provided with an upper connecting shaft and a first connecting shaft; the steering cross shaft assembly comprises a rotating shaft and a driven shaft, the upper end of the rotating shaft is connected with the steering wheel, the upper end of the driven shaft is connected with the lower end of the rotating shaft through an upper cross shaft joint, a lower cross shaft joint is arranged at the lower end of the driven shaft, and the lower cross shaft joint is connected with the upper connecting shaft; and the steering column pipe rotatably sleeves the rotating shaft and is rotatably connected to a vehicle frame, and a center point of the upper cross shaft joint is located on a rotation axis of the steering column pipe relative to the vehicle frame. According to the steering system, the assembly process is reduced, the installation precision is high, and the cost is low; in addition, a steering gap of the steering wheel is reduced; and besides, the precision of the steering system can be further improved, and the adjustment requirement of the steering wheel is met.

Description

technical field [0001] The invention relates to the field of all-terrain vehicles, in particular to a steering system of an all-terrain vehicle and an all-terrain vehicle with the same. Background technique [0002] In the technology related to the steering system of a four-wheel all-terrain vehicle, it is usually necessary to set a power steering system to help the driver to manipulate the vehicle more easily. One end of the power steering system is connected to the steering wheel, and the other end is connected to the steering gear. The steering wheel 4' is connected with the power steering system 1', usually through a pair of upper cross cardan shafts 51', sliding forks 52' and rotating shafts 53', as Figure 9 As shown, this connection method has many parts, cumbersome assembly and high cost. In addition, due to the sliding fork structure with internal and external splines, the steering wheel may be vacant, and the steering feel is poor, which will affect the driver's j...

Problems solved by technology

The steering wheel 4' is connected with the power steering system 1', usually through a pair of upper cross cardan shafts 51', sliding forks 52' and rotating shafts 53', as Figure 9 As shown, this connection method has many parts, cumbersome assembly and high cost

In addition, due to the sliding fork structure with internal and external splines, it may cause the steering wheel to be vacant, and the steering feel is poor, which will affect the driver's judgment on road conditions and vehicles during intense driving, thus posing a great safety hazard
